Calculate Income Tax 2019 20

Module A: Introduction & Importance

The 2019-20 tax year (6 April 2019 to 5 April 2020) introduced several important changes to UK income tax calculations that continue to affect millions of taxpayers. Understanding your 2019-20 tax liability remains crucial for several reasons:

• Tax refunds: You may be entitled to claim back overpaid tax from this period (up to 4 years back)
• Financial planning: Historical tax data helps predict future liabilities
• Self-assessment: Required for completing late tax returns or amendments
• Employment verification: Often needed for mortgage applications or visa processes

The 2019-20 tax year saw the personal allowance increase to £12,500 (from £11,850 in 2018-19), while the higher rate threshold rose to £50,000. Scottish taxpayers faced different rates, with the starter rate increasing to 19% and new intermediate bands introduced.

According to HMRC’s 2019-20 statistics, over 31 million individuals paid income tax this year, with the average taxpayer contributing £4,200 in income tax and £2,800 in National Insurance.

Pension Adjustments

Pension contributions reduce your taxable income through:

1. Relief at source: Basic rate tax relief (20%) added to your pension pot
2. Net pay arrangement: Contributions taken before tax (common in workplace pensions)
3. Salary sacrifice: Reduces your gross pay before tax calculation

Our calculator automatically applies the correct pension tax relief based on your selected tax code and income level, following HMRC’s pension tax relief rules.

Module D: Real-World Examples

Case Study 1: Basic Rate Taxpayer

Scenario: Emma earns £30,000 annually with tax code 1250L, no pension contributions, and no student loan.

Calculation:

• Taxable income: £30,000 – £12,500 (allowance) = £17,500
• Income tax: £17,500 × 20% = £3,500
• NI: (£30,000 – £8,632) × 12% + (£0) × 2% = £2,564.16
• Take home: £30,000 – £3,500 – £2,564.16 = £23,935.84

Case Study 2: Higher Rate with Pension

Scenario: James earns £60,000 with £5,000 pension contributions (net pay), tax code 1250L, and Plan 2 student loan.

Calculation:

• Taxable income: £60,000 – £5,000 (pension) – £12,500 = £42,500
• Income tax: £37,500 × 20% + £5,000 × 40% = £9,500
• NI: (£60,000 – £5,000 – £8,632) × 12% + (£5,000) × 2% = £5,144.16
• Student loan: (£60,000 – £5,000 – £25,725) × 9% = £2,574.75
• Take home: £60,000 – £5,000 – £9,500 – £5,144.16 – £2,574.75 = £37,781.09

Case Study 3: Scottish Additional Rate

Scenario: Fiona earns £160,000 in Scotland with tax code 1250L and no student loan.

Calculation:

• Taxable income: £160,000 – £12,500 = £147,500
• Income tax:
  • £2,049 × 19% = £389.31
  • £10,395 × 20% = £2,079
  • £18,486 × 21% = £3,881.06
  • £18,486 × 41% = £7,580.26
  • £98,184 × 46% = £45,164.64
  • Total: £59,094.27
• NI: (£160,000 – £8,632) × 12% + (£0) × 2% = £18,164.16
• Take home: £160,000 – £59,094.27 – £18,164.16 = £82,741.57

Module F: Expert Tips

Maximising Your Take-Home Pay

1. Salary sacrifice schemes: Can reduce both tax and NI liabilities by up to 42% (depending on your tax band)
2. Pension contributions: Every £100 contributed costs you just £58 (if higher rate taxpayer) due to tax relief
3. Marriage allowance: Transfer £1,250 of personal allowance to your spouse if you earn under £12,500
4. Claim work expenses: Uniforms, tools, or professional subscriptions can be claimed back
5. Charitable donations: Gift Aid increases the value of your donation by 25% and can reduce your tax bill

Common Mistakes to Avoid

• Ignoring your tax code: Wrong codes (like 1185L when you should have 1250L) can cost hundreds
• Forgetting benefits: Company cars, health insurance, and gym memberships are taxable benefits
• Missing deadlines: Late self-assessment returns incur £100 penalties even if you owe no tax
• Not claiming reliefs: Many taxpayers miss out on blind person’s allowance or working from home relief
• Incorrect student loan plan: Choosing Plan 1 when you’re on Plan 2 (or vice versa) affects repayments

When to Seek Professional Help

Consider consulting an accountant if you:

• Have income from multiple sources (employment, self-employment, property)
• Received a P800 calculation from HMRC that seems incorrect
• Are claiming complex expenses or capital allowances
• Have foreign income or assets
• Are subject to the high-income child benefit charge

Module G: Interactive FAQ

Why do I need to calculate 2019-20 taxes now in [current year]?

You can claim tax refunds for up to 4 previous tax years. The 2019-20 tax year becomes unavailable for new claims after 5 April 2024. Common reasons for overpayment include:

• Wrong tax code applied by your employer
• Leaving a job and not working for a period
• Work expenses you didn’t claim
• Emergency tax applied when starting a new job

Use our calculator to check if you’re due a refund, then claim through HMRC’s refund service.

How does the Scottish income tax system differ from the rest of the UK?

Scotland has had devolved income tax powers since 2017. For 2019-20, the key differences were:

Income Range	Scotland Rate	UK Rate
£12,501-£14,549	19%	20%
£14,550-£24,944	20%	20%
£24,945-£43,430	21%	20%
£43,431-£150,000	41%	40%
Over £150,000	46%	45%

Our calculator automatically adjusts for Scottish rates when you select the Scottish taxpayer option.

What’s the difference between tax avoidance and tax evasion?

Tax avoidance is legal and involves arranging your affairs to minimise tax within the law. Examples include:

• Contributing to a pension scheme
• Using ISA allowances
• Claiming legitimate work expenses
• Transferring assets to a spouse

Tax evasion is illegal and involves deliberately misleading HMRC or not declaring income. Examples include:

• Not declaring cash-in-hand payments
• Falsifying expense claims
• Hiding offshore income
• Using fake invoices

HMRC’s guidance on offshore income provides clear examples of what constitutes evasion.

How does student loan repayment work with multiple jobs?

If you have multiple jobs, student loan repayments are calculated separately for each employment. The key points:

1. Each employer deducts 9% from earnings above the threshold (£18,935 for Plan 1 or £25,725 for Plan 2)
2. You might repay more than you owe if your total income fluctuates
3. HMRC will refund any overpayments when your loan is fully repaid
4. Self-employed individuals make repayments through Self Assessment

Example: With two jobs paying £20,000 each (total £40,000) on Plan 2:

• Job 1: (£20,000 – £25,725) × 0% = £0 (no repayment)
• Job 2: (£20,000 – £25,725) × 0% = £0 (no repayment)
• Total repayment: £0 (but you actually owe 9% of £14,275 = £1,284.75)

In this case, you’d need to make a voluntary repayment or wait for HMRC to adjust after your Self Assessment.

Can I still amend my 2019-20 tax return?

Yes, you can amend your 2019-20 Self Assessment tax return until 31 January 2022 (12 months after the original filing deadline). After this date:

• You can write to HMRC with the corrections
• For overpayments, you have until 5 April 2024 to claim a refund
• For underpayments, HMRC can collect through your tax code (if under £3,000)

To amend online:

1. Log in to your HMRC account
2. Select “Self Assessment”
3. Choose “More Self Assessment details”
4. Select “At a glance” then “Tax return options”
5. Choose “Amend Self Assessment return”

You’ll need your Unique Taxpayer Reference (UTR) and the activation code HMRC sent when you registered.
