Comprehensive Guide: How to Calculate National Insurance in the UK (2024/25)

National Insurance (NI) is a fundamental part of the UK’s social security system, funding state benefits including the State Pension, statutory sick pay, and maternity leave. Understanding how to calculate your National Insurance contributions is essential for financial planning and ensuring you’re paying the correct amount.

What is National Insurance?

National Insurance is a tax on earnings paid by employees, employers, and the self-employed. The amount you pay depends on:

Your employment status (employed or self-employed)
How much you earn
Your National Insurance category letter
Whether you have any gaps in your National Insurance record

National Insurance Categories

Your National Insurance category determines how much you pay. The most common categories for employees are:

Category Letter	Description	Employee Rate (2024/25)	Employer Rate (2024/25)
A	Most employees	12% on earnings between £242-£967 per week 2% on earnings above £967	13.8% on earnings above £175 per week
B	Married women and widows entitled to pay reduced NI	5.85% on earnings between £242-£967 per week 2% on earnings above £967	13.8% on earnings above £175 per week
C	Employees over State Pension age	0%	13.8% on earnings above £175 per week
H	Apprentices under 25	0% on earnings below £967 per week 2% on earnings above £967	13.8% on earnings above £175 per week
J	Employees who can defer NI because they’re paying it in another job	2% on all earnings	13.8% on earnings above £175 per week

National Insurance Thresholds for 2024/25

The amounts you pay depend on how much you earn and which thresholds you cross:

Threshold	Weekly Amount	Annual Amount	Description
Primary Threshold (PT)	£242	£12,570	Earnings below this: 0% NI Earnings above this up to UEL: 12% NI
Secondary Threshold (ST)	£175	£9,100	Employers start paying NI
Upper Earnings Limit (UEL)	£967	£50,270	Earnings above this: 2% NI
Upper Secondary Threshold (UST)	£967	£50,270	Employers pay 13.8% up to this point
Apprentice Upper Secondary Threshold (AUST)	£967	£50,270	Employers pay 0% for apprentices under 21

How to Calculate National Insurance for Employees

Determine your category letter – This is usually on your payslip (most people are category A)
Calculate your weekly earnings – Divide your annual salary by 52
Apply the thresholds:
- Earnings below £242/week: £0 NI
- Earnings between £242-£967: 12% NI on the amount above £242
- Earnings above £967: 12% on £725 (£967-£242) + 2% on earnings above £967
Multiply by 52 for your annual NI contribution

National Insurance for the Self-Employed

If you’re self-employed, you pay two types of National Insurance:

Class 2 NI – £3.45 per week (if profits are £6,725 or more per year)
Class 4 NI – 9% on profits between £12,570 and £50,270, plus 2% on profits above £50,270

Example calculation for a self-employed person with £30,000 annual profits:

Class 2: £3.45 × 52 = £179.40 per year
Class 4: 9% of (£30,000 – £12,570) = £1,575.93
Total NI = £179.40 + £1,575.93 = £1,755.33 per year

National Insurance for Employers

Employers also pay National Insurance contributions on their employees’ earnings. The rates for 2024/25 are:

13.8% on earnings above £175 per week (£9,100 per year)
0% for employees under 21 (up to £967 per week)
0% for apprentices under 25 (up to £967 per week)

National Insurance and State Pension

Your National Insurance record determines your eligibility for the State Pension. You typically need:

10 qualifying years to get any State Pension
35 qualifying years to get the full State Pension (£221.20 per week in 2024/25)

You can check your National Insurance record and get a State Pension forecast on the GOV.UK website.

National Insurance Gaps and Voluntary Contributions

If you have gaps in your National Insurance record (for example, if you were unemployed, self-employed but didn’t pay enough, or lived abroad), you might be able to make voluntary contributions to fill these gaps.

The cost of voluntary Class 3 contributions for 2024/25 is £17.45 per week. You can usually pay for the past 6 years. It’s often worth filling gaps if:

You’re close to the 10-year minimum for any State Pension
You’re close to the 35-year maximum for full State Pension
The cost of filling the gap is less than the extra State Pension you’d receive

National Insurance for Different Age Groups

The amount of National Insurance you pay depends on your age:

Under 16: Don’t pay National Insurance
16-20 (not apprentice): Pay standard rates if earning above thresholds
Apprentices under 25: Pay 0% on earnings below £967/week, 2% above
Over State Pension age: Don’t pay employee contributions (but may still pay if self-employed)

National Insurance and Multiple Jobs

If you have more than one job, you’ll have a separate National Insurance calculation for each employment. However:

You only get one personal allowance (the Primary Threshold)
Your second job will have NI deducted from the first pound
You might be able to defer NI in one job if you’re paying enough in another

National Insurance for Directors

Company directors have special rules for National Insurance:

NI is calculated annually based on annual earnings
The annual Primary Threshold is £12,570
The annual Upper Earnings Limit is £50,270
Directors can choose how to pay themselves (salary + dividends) to minimize NI

National Insurance and Pensions

If you’re in a workplace pension scheme, your pension contributions are taken from your salary before National Insurance is calculated. This can reduce the amount of NI you pay.

Example: If you earn £40,000 and contribute 5% to your pension:

Pensionable pay: £40,000 × 95% = £38,000
NI is calculated on £38,000 instead of £40,000
This could save you several hundred pounds in NI per year

National Insurance for Non-Residents

If you’re not a UK resident but work in the UK, you’ll usually pay National Insurance if:

You’re an employee working in the UK
You’re self-employed with a business in the UK

There are special rules if you’re posted to the UK temporarily by an overseas employer. The UK has social security agreements with many countries to avoid paying NI in both countries.

National Insurance and Benefits

Your National Insurance contributions count towards:

State Pension
Contribution-based Jobseeker’s Allowance
Contribution-based Employment and Support Allowance
Maternity Allowance
Bereavement Support Payment

National Insurance Refunds

In some cases, you might be able to claim a National Insurance refund:

If you’ve overpaid because you had more than one job
If you left the UK but continued paying NI
If you were employed and self-employed and paid too much

You can claim a refund by contacting HMRC. The time limit for claiming is usually 6 years from the end of the tax year you’re claiming for.

National Insurance and Tax Codes

Your tax code can affect how much National Insurance you pay. Common situations include:

Emergency tax codes: Might result in incorrect NI deductions
Wrong tax code: Could mean you’re paying too much or too little NI
K codes: Used when you owe tax from previous years, which can affect NI calculations

If you think your tax code is wrong, you should contact HMRC to have it corrected.

National Insurance for the 2024/25 Tax Year

The key rates and thresholds for the 2024/25 tax year (6 April 2024 to 5 April 2025) are:

Primary Threshold: £242 per week (£12,570 per year)
Secondary Threshold: £175 per week (£9,100 per year)
Upper Earnings Limit: £967 per week (£50,270 per year)
Employee rate: 12% between PT and UEL, 2% above UEL
Employer rate: 13.8% above ST
Class 2 rate: £3.45 per week
Class 4 rate: 9% between £12,570 and £50,270, 2% above £50,270

National Insurance and the Triple Lock

The State Pension triple lock guarantees that the State Pension increases each year by the highest of:

Earnings growth (average weekly earnings)
Price inflation (CPI)
2.5%

For 2024/25, the State Pension increased by 8.5% (based on earnings growth), taking the full new State Pension to £221.20 per week.

National Insurance and the Lifetime Allowance

While the Lifetime Allowance for pensions was abolished in April 2024, National Insurance contributions still play a role in your overall retirement planning. The amount of NI you pay affects:

Your State Pension entitlement
Your take-home pay during your working life
Your ability to make additional voluntary contributions

National Insurance and Scotland

National Insurance rules are the same across the UK, including Scotland. However, income tax rates are different in Scotland, which can affect your overall take-home pay calculations. The Scottish income tax bands for 2024/25 are:

Band	Tax Rate	Taxable Income Range
Starter Rate	19%	£12,571 to £14,876
Basic Rate	20%	£14,877 to £26,561
Intermediate Rate	21%	£26,562 to £43,662
Higher Rate	42%	£43,663 to £150,000
Top Rate	47%	Over £150,000

National Insurance and Wales

Wales follows the same National Insurance rules as England. The Welsh Rate of Income Tax applies to Welsh taxpayers, but this doesn’t affect National Insurance calculations.

National Insurance and Northern Ireland

National Insurance in Northern Ireland works the same way as in the rest of the UK. The rates and thresholds are identical.

National Insurance for Armed Forces

Members of the armed forces have special National Insurance arrangements:

They pay Class 1 National Insurance like other employees
They’re automatically enrolled in the Armed Forces Pension Scheme
They may be eligible for early access to their pension in some circumstances

National Insurance for Civil Servants

Civil servants pay National Insurance in the same way as other employees. However, they’re typically enrolled in one of the Civil Service pension schemes, which may affect their overall retirement planning.

National Insurance for Teachers

Teachers pay National Insurance through PAYE like other employees. They’re also members of the Teachers’ Pension Scheme, which provides additional retirement benefits.

National Insurance for NHS Workers

NHS workers pay National Insurance through PAYE. They’re typically members of the NHS Pension Scheme, which is one of the most generous public sector pension schemes.

National Insurance for Police Officers

Police officers pay National Insurance through PAYE. They have their own police pension scheme, which provides retirement benefits based on their service and final salary.

National Insurance for Firefighters

Firefighters pay National Insurance through PAYE. They’re members of the Firefighters’ Pension Scheme, which has different rules depending on when they joined the service.

National Insurance and Maternity Leave

During maternity leave, your National Insurance contributions depend on your situation:

If you’re receiving Statutory Maternity Pay (SMP), you’ll continue to pay NI on these payments
If you’re not receiving SMP (for example, if you don’t qualify), you won’t pay NI but may get National Insurance credits
National Insurance credits can help protect your State Pension and other benefits

National Insurance and Paternity Leave

During paternity leave, you’ll pay National Insurance on any Statutory Paternity Pay you receive, just like with regular earnings.

National Insurance and Shared Parental Leave

Shared Parental Pay is treated like other statutory payments for National Insurance purposes. You’ll pay NI on these payments if they exceed the Primary Threshold.

National Insurance and Adoption Leave

Statutory Adoption Pay is subject to National Insurance contributions in the same way as other statutory payments.

National Insurance and Sick Leave

If you’re off work sick, your National Insurance contributions depend on what you’re receiving:

Statutory Sick Pay (SSP): You’ll pay NI on SSP if it exceeds the Primary Threshold
Company sick pay: Treated like normal earnings for NI purposes
No pay: You might get National Insurance credits to protect your record

National Insurance and Redundancy

If you’re made redundant, your redundancy pay is treated differently for National Insurance:

Statutory redundancy pay is not subject to National Insurance
Any additional redundancy pay above the statutory amount may be subject to NI
You might be eligible for National Insurance credits while unemployed

National Insurance and Self-Assessment

If you’re self-employed or have other income that requires a Self Assessment tax return, you’ll need to calculate and report your National Insurance contributions as part of this process.

The deadline for online Self Assessment tax returns is 31 January following the end of the tax year. Any Class 2 and Class 4 National Insurance due must be paid by the same deadline.

National Insurance and Payment on Account

If you’re self-employed and your Self Assessment bill is more than £1,000, you’ll usually have to make payments on account. These are advance payments towards your next tax bill, which include any National Insurance due.

National Insurance and the Marriage Allowance

The Marriage Allowance doesn’t directly affect National Insurance, but it can reduce your income tax bill, which might indirectly affect how much you have available to pay National Insurance.

National Insurance and the Blind Person’s Allowance

The Blind Person’s Allowance increases the amount of income you can have before paying income tax, but it doesn’t affect National Insurance calculations.

National Insurance and the Marriage Allowance

If you transfer part of your Personal Allowance to your spouse or civil partner using the Marriage Allowance, this doesn’t affect your National Insurance calculations, which are based on your actual earnings.

National Insurance and Student Loans

Student loan repayments are deducted from your pay after National Insurance but before income tax. They don’t directly affect your National Insurance calculations, but they do reduce your take-home pay.

National Insurance and the Apprenticeship Levy

The Apprenticeship Levy is paid by employers with a pay bill over £3 million per year. It’s separate from National Insurance but is calculated as 0.5% of the employer’s pay bill (minus a £15,000 allowance).

National Insurance and the Employment Allowance

The Employment Allowance allows eligible employers to reduce their National Insurance bill by up to £5,000 per year. This can be particularly beneficial for small businesses.

National Insurance and IR35

IR35 rules affect off-payroll workers (contractors working through their own limited company). If you’re caught by IR35, you’ll pay National Insurance as if you were an employee, which can significantly increase your NI bill.

National Insurance and the Construction Industry Scheme (CIS)

If you work in the construction industry, you might be paid under the Construction Industry Scheme (CIS). Under CIS:

Contractors deduct 20% from your payments (or 30% if you’re not registered)
This counts as advance payments towards your tax and National Insurance bill
You’ll need to complete a Self Assessment tax return to calculate your final liability

National Insurance and the Gig Economy

Workers in the gig economy (like Uber drivers or Deliveroo riders) are typically classed as self-employed, meaning they’re responsible for paying their own National Insurance through Self Assessment.

However, there have been legal challenges about employment status in the gig economy, and some workers have been reclassified as employees, which would change their National Insurance obligations.

National Insurance and the Minimum Wage

The National Minimum Wage and National Living Wage don’t directly affect National Insurance calculations, but they do determine the minimum you can earn. The rates for 2024/25 are:

Age 23 and over (National Living Wage): £11.44 per hour
Age 21-22: £11.44 per hour
Age 18-20: £8.60 per hour
Under 18: £6.40 per hour
Apprentice rate: £6.40 per hour

National Insurance and the Real Living Wage

The Real Living Wage (calculated by the Living Wage Foundation) is higher than the government’s National Living Wage. It’s currently £12.00 per hour across the UK and £13.15 in London. Earning the Real Living Wage would mean paying more in National Insurance than someone earning the minimum wage.

National Insurance and the State Pension Age

The State Pension age is currently 66 for both men and women. It’s scheduled to rise to 67 between 2026 and 2028, and to 68 between 2044 and 2046 (though this might be brought forward).

Once you reach State Pension age, you stop paying National Insurance if you’re employed. However, if you’re self-employed, you continue to pay Class 4 contributions on any profits above the threshold.

National Insurance and the New State Pension

The New State Pension was introduced in April 2016. To get the full New State Pension (£221.20 per week in 2024/25), you need 35 qualifying years of National Insurance contributions or credits.

If you have gaps in your National Insurance record, you might get less than the full amount. You can check your State Pension forecast on the GOV.UK website.

National Insurance and the Old State Pension

If you reached State Pension age before 6 April 2016, you’ll be on the old State Pension system. The rules are different:

Men need 44 qualifying years for the full basic State Pension
Women need 39 qualifying years for the full basic State Pension
The full basic State Pension is £169.50 per week in 2024/25
You might also get an additional State Pension based on your earnings

National Insurance and the State Pension Top-Up

If you’re already receiving your State Pension or have reached State Pension age, you might be able to increase it by paying voluntary Class 3 National Insurance contributions. This is known as ‘topping up’ your State Pension.

The cost depends on your age and how much extra pension you want to get. You can usually buy up to £25 per week extra State Pension.

National Insurance and the State Pension Forecast

It’s important to check your State Pension forecast regularly, especially as you approach retirement age. Your forecast will tell you:

How much State Pension you’re on track to get
When you can get it
Whether you can increase it (for example, by paying voluntary contributions)

You can check your forecast online at any time. The service is available 24 hours a day.

National Insurance and the State Pension Age Review

The government reviews the State Pension age regularly to take account of increases in life expectancy. The next review is due to be published by 7 May 2027.

Any changes to the State Pension age require at least 10 years’ notice, so you’ll have plenty of time to plan for your retirement.

National Insurance and the Triple Lock Plus

The Conservative Party has proposed a ‘Triple Lock Plus’ policy, which would add a fourth measure to the State Pension increase calculation: the average earnings growth of the over-50s. This could lead to higher State Pension increases in the future.

National Insurance and the Pensions Dashboard

The Pensions Dashboard is a new service that will allow you to see all your pension information in one place, including your State Pension and any workplace or personal pensions. This will help you plan for retirement more effectively.

The dashboard is being introduced gradually, with all providers expected to be connected by October 2026.

National Insurance and the Lifetime ISA

The Lifetime ISA can be used to save for retirement or to buy your first home. You can pay in up to £4,000 each year until you’re 50, and the government will add a 25% bonus to your savings.

While the Lifetime ISA doesn’t directly affect your National Insurance, it’s an important part of retirement planning alongside your State Pension.

National Insurance and Auto-Enrolment

Auto-enrolment means that all employers must automatically enroll eligible workers into a workplace pension scheme. This doesn’t affect your National Insurance directly, but it does reduce your take-home pay (as pension contributions are deducted before tax and NI).

The minimum contributions are currently 8% of your qualifying earnings, with at least 3% coming from your employer.

National Insurance and Salary Sacrifice

Salary sacrifice is an arrangement where you give up part of your salary in exchange for a non-cash benefit, like extra pension contributions or childcare vouchers. This can reduce your National Insurance bill because you’re paying NI on a lower salary.

However, your salary after sacrifice must not go below the National Minimum Wage.

National Insurance and the Trivial Commutation Rules

The trivial commutation rules allow you to take small pension pots as a lump sum. If you take a trivial commutation lump sum, it’s taxed as income, which could affect your National Insurance calculations for that year.

National Insurance and the Annual Allowance

The Annual Allowance is the maximum amount you can contribute to your pension each year while still receiving tax relief. It’s currently £60,000 (or 100% of your earnings if less).

If you exceed the Annual Allowance, you’ll face a tax charge, but this doesn’t directly affect your National Insurance.

National Insurance and the Money Purchase Annual Allowance

If you’ve already started drawing from a defined contribution pension, the Money Purchase Annual Allowance (MPAA) applies. This reduces the amount you can pay into a defined contribution pension to £10,000 per year.

Again, this affects your pension planning but not your National Insurance directly.

National Insurance and the Tapered Annual Allowance

If you have a high income (over £260,000), your Annual Allowance is reduced by £1 for every £2 you earn over this threshold, down to a minimum of £10,000.

This is another pension rule that doesn’t directly affect National Insurance but is important for high earners to understand.

National Insurance and the Pension Protection Fund

The Pension Protection Fund protects your pension if your employer goes bust. It doesn’t affect your National Insurance, but it’s an important safety net for your retirement savings.

National Insurance and the Financial Assistance Scheme

The Financial Assistance Scheme helps people who lost their occupational pension when their employer became insolvent. Like the Pension Protection Fund, it doesn’t affect National Insurance but provides important protection.

National Insurance and the Pension Wise Service

Pension Wise is a free government service that offers guidance on your pension options. While it doesn’t deal with National Insurance directly, understanding your pension options can help you plan your retirement income alongside your State Pension.

You can book a free appointment if you’re 50 or over and have a defined contribution pension.

National Insurance and the Pension Tracing Service

The Pension Tracing Service helps you find contact details for pension schemes you might have lost track of. This can help you get a complete picture of your retirement income, alongside your State Pension.

National Insurance and the Pension Credit

Pension Credit is a benefit for people over State Pension age on a low income. It tops up your weekly income to £218.15 if you’re single or £332.95 if you’re a couple.

Your National Insurance record affects your State Pension, which in turn affects your eligibility for Pension Credit.

National Insurance and the Winter Fuel Payment

The Winter Fuel Payment is a tax-free payment to help with heating costs if you were born before 25 September 1957. It’s not means-tested, so you can get it regardless of your income or National Insurance record.

National Insurance and the Cold Weather Payment

The Cold Weather Payment is a £25 payment for each 7-day period of very cold weather between 1 November and 31 March. You might be eligible if you’re receiving certain benefits, regardless of your National Insurance record.

National Insurance and the Warm Home Discount

The Warm Home Discount is a £150 discount on your electricity bill if you’re on a low income or receive the Guarantee Credit element of Pension Credit. Your National Insurance record doesn’t directly affect your eligibility.

National Insurance and the Disability Benefits

Disability benefits like Personal Independence Payment (PIP) and Disability Living Allowance (DLA) are not affected by your National Insurance record. They’re not means-tested, so you can claim them regardless of your income or savings.

National Insurance and the Carer’s Allowance

Carer’s Allowance is £81.90 per week if you care for someone at least 35 hours a week. You might get National Insurance credits if you’re eligible for Carer’s Allowance but don’t actually receive it (for example, because you’re earning too much).

National Insurance and the Universal Credit

Universal Credit is replacing several means-tested benefits. Your National Insurance record doesn’t directly affect your eligibility, but your earnings (after tax and NI) do affect how much you can claim.

National Insurance and the Jobseeker’s Allowance

There are two types of Jobseeker’s Allowance:

Contribution-based JSA: Depends on your National Insurance record
Income-based JSA: Depends on your income and savings

For contribution-based JSA, you need to have paid enough National Insurance in the last 2-3 years.

National Insurance and the Employment and Support Allowance

Like Jobseeker’s Allowance, there are two types of Employment and Support Allowance (ESA):

Contribution-based ESA: Depends on your National Insurance record
Income-related ESA: Depends on your income and savings

For contribution-based ESA, you need to have paid enough National Insurance in the last 2-3 years.

National Insurance and the Bereavement Support Payment

Bereavement Support Payment is available if your husband, wife or civil partner died before 6 April 2017. Your eligibility depends on your late spouse or civil partner’s National Insurance record.

National Insurance and the Bereavement Allowance

Bereavement Allowance is available if your husband, wife or civil partner died on or after 6 April 2017. Again, eligibility depends on their National Insurance record.

National Insurance and the Guardian’s Allowance

Guardian’s Allowance is a tax-free payment if you’re bringing up a child whose parents have died. You might get it if you’re entitled to Child Benefit for the child and at least one of the parents paid enough National Insurance or died as a result of their work.

National Insurance and the Child Benefit

Child Benefit is usually paid to the person responsible for a child under 16 (or under 20 if they’re in approved education or training). It’s not affected by your National Insurance record, but if you or your partner earns over £60,000, you might have to pay the High Income Child Benefit Charge.

National Insurance and the High Income Child Benefit Charge

The High Income Child Benefit Charge claws back Child Benefit if you or your partner earns over £60,000. The charge is 1% of the Child Benefit for every £100 earned over £50,000, up to 100% if you earn £60,000 or more.

This charge is collected through Self Assessment and doesn’t affect your National Insurance directly.

National Insurance and the Marriage Allowance

The Marriage Allowance allows you to transfer 10% of your Personal Allowance to your spouse or civil partner if you earn less than the Personal Allowance (£12,570 in 2024/25) and they’re a basic rate taxpayer.

This doesn’t affect your National Insurance, but it can reduce your income tax bill.

National Insurance and the Blind Person’s Allowance

The Blind Person’s Allowance increases your Personal Allowance if you’re registered blind. This reduces your income tax bill but doesn’t affect your National Insurance.

National Insurance and the Seafarers’ Earnings Deduction

The Seafarers’ Earnings Deduction gives 100% tax relief on earnings from employment on a ship if you’re away from the UK for at least 183 days in a tax year. This can significantly reduce your income tax bill but doesn’t affect your National Insurance.

National Insurance and the Foreign Earnings Deduction

The Foreign Earnings Deduction gives tax relief on up to £100,000 of foreign earnings if you’re a UK resident working abroad. Again, this affects income tax but not National Insurance.

National Insurance and the Rent a Room Scheme

The Rent a Room Scheme lets you earn up to £7,500 per year tax-free from renting out a room in your home. This income doesn’t count for National Insurance purposes.

National Insurance and the Trading Allowance

The Trading Allowance lets you earn up to £1,000 per year from self-employment or casual services without telling HMRC. If you earn more than this, you need to register as self-employed and pay National Insurance.

National Insurance and the Property Allowance

The Property Allowance lets you earn up to £1,000 per year from property income without telling HMRC. Like the Trading Allowance, if you earn more than this, you need to declare it and may need to pay National Insurance.

National Insurance and the Personal Savings Allowance

The Personal Savings Allowance lets basic rate taxpayers earn £1,000 in savings interest tax-free (£500 for higher rate taxpayers). This doesn’t affect National Insurance.

National Insurance and the Dividend Allowance

The Dividend Allowance was reduced to £500 in April 2024. Dividends above this amount are taxed, but they don’t count for National Insurance purposes.

National Insurance and the Capital Gains Tax Allowance

The Capital Gains Tax allowance was reduced to £3,000 in April 2024. Capital gains don’t count for National Insurance.

National Insurance and the Inheritance Tax Threshold

The Inheritance Tax threshold (nil-rate band) is £325,000, with an additional £175,000 for a main residence passed to direct descendants. Inheritance Tax doesn’t affect National Insurance.

National Insurance and the Stamp Duty Land Tax

Stamp Duty Land Tax is a tax on property purchases. It doesn’t affect National Insurance.

National Insurance and the Council Tax

Council Tax is a local tax on domestic property. It doesn’t affect National Insurance, though your ability to pay it might be affected by how much NI you pay.

National Insurance and the Vehicle Excise Duty

Vehicle Excise Duty (road tax) doesn’t affect National Insurance, though both are taxes that reduce your disposable income.

National Insurance and the Insurance Premium Tax

Insurance Premium Tax is a tax on insurance premiums. It doesn’t affect National Insurance.

National Insurance and the Air Passenger Duty

Air Passenger Duty is a tax on flights. It doesn’t affect National Insurance.

National Insurance and the Alcohol Duty

Alcohol Duty is a tax on alcoholic drinks. It doesn’t affect National Insurance.

National Insurance and the Tobacco Duty

Tobacco Duty is a tax on tobacco products. It doesn’t affect National Insurance.

National Insurance and the Fuel Duty

Fuel Duty is a tax on petrol, diesel, and other fuels. It doesn’t affect National Insurance.

National Insurance and the Value Added Tax (VAT)

VAT is a tax on goods and services. If you’re VAT-registered, you charge VAT on your sales and can reclaim VAT on your purchases. This doesn’t directly affect your National Insurance, though it does affect your business’s cash flow.

National Insurance and the Corporation Tax

Corporation Tax is a tax on company profits. If you’re a company director, your salary and dividends affect your National Insurance, but the company’s Corporation Tax doesn’t directly affect your personal NI.

National Insurance and the Business Rates

Business Rates are a tax on non-domestic properties. They don’t affect National Insurance.

National Insurance and the Climate Change Levy

The Climate Change Levy is a tax on energy used by businesses. It doesn’t affect National Insurance.

National Insurance and the Aggregates Levy

The Aggregates Levy is a tax on sand, gravel, and rock. It doesn’t affect National Insurance.

National Insurance and the Landfill Tax

Landfill Tax is a tax on waste sent to landfill. It doesn’t affect National Insurance.

National Insurance and the Soft Drinks Industry Levy

The Soft Drinks Industry Levy (sugar tax) doesn’t affect National Insurance.

National Insurance and the Plastic Packaging Tax

The Plastic Packaging Tax applies to plastic packaging with less than 30% recycled content. It doesn’t affect National Insurance.
