UK Income Tax Calculator 2019-20
Introduction & Importance of 2019-20 Income Tax Calculation
The 2019-20 tax year (6 April 2019 to 5 April 2020) represents a critical period for UK taxpayers, with significant implications for personal finances. Understanding how to calculate your income tax for this year is essential for accurate financial planning, tax efficiency, and compliance with HMRC regulations.
This period saw several important tax changes, including adjustments to personal allowances, tax bands, and National Insurance thresholds. The standard Personal Allowance increased to £12,500, while the higher rate threshold rose to £50,000. These changes directly impact how much tax individuals pay on their income.
Accurate tax calculation helps you:
- Plan your budget effectively by knowing your net income
- Avoid underpayment penalties from HMRC
- Identify potential tax savings through allowances and reliefs
- Prepare accurate Self Assessment returns if required
- Make informed decisions about pension contributions and charitable giving
For the 2019-20 tax year, HMRC processed over 31 million Self Assessment returns, with more than £200 billion collected in income tax. Understanding your position within this system can help you optimize your financial situation.

Formula & Methodology Behind the 2019-20 Tax Calculation
Our calculator uses the exact tax rules and rates that applied during the 2019-20 UK tax year. Here’s the detailed methodology:
1. Personal Allowance Calculation
The standard Personal Allowance for 2019-20 was £12,500. However, this tapers away by £1 for every £2 earned above £100,000, reaching zero at £125,000.
Formula: Adjusted Allowance = MAX(0, 12500 - (0.5 × (Income - 100000)))
2. Income Tax Bands and Rates
| Tax Band | Taxable Income Range | Tax Rate | Tax Calculation |
|---|---|---|---|
| Personal Allowance | Up to £12,500 | 0% | £0 tax on this portion |
| Basic Rate | £12,501 to £50,000 | 20% | 20% on income in this band |
| Higher Rate | £50,001 to £150,000 | 40% | 40% on income in this band |
| Additional Rate | Over £150,000 | 45% | 45% on income above £150,000 |
3. National Insurance Contributions
NI calculations differ for employed (Class 1) and self-employed (Class 2 & 4) individuals:
| Type | Weekly Earnings Threshold | Rate | 2019-20 Annual Equivalent |
|---|---|---|---|
| Class 1 (Employed) | £166-£962/week | 12% | £8,632-£50,024 |
| Class 1 (Employed) | Over £962/week | 2% | Over £50,024 |
| Class 4 (Self-Employed) | £8,632-£50,000 | 9% | On profits in this range |
| Class 4 (Self-Employed) | Over £50,000 | 2% | On profits above £50,000 |
4. Pension Contributions and Tax Relief
Pension contributions receive tax relief at your marginal rate. For basic rate taxpayers, this is automatically applied at 20%. Higher rate taxpayers can claim additional relief through Self Assessment.
Formula: Tax Relief = Contribution × Marginal Tax Rate
5. Gift Aid and Charitable Donations
Gift Aid donations extend your basic rate tax band by 10% of the donation amount. For example, a £1,000 donation increases your basic rate band by £100.
Formula: Adjusted Basic Rate Band = Standard Band + (0.1 × Donation)
6. Student Loan Repayments
Repayments are calculated as 9% (Plan 1/2) or 6% (Postgraduate) of income above the threshold:
- Plan 1: 9% of income over £18,935
- Plan 2: 9% of income over £25,725
- Postgraduate: 6% of income over £21,000
7. Scottish Taxpayers
Note that Scottish taxpayers had different rates:
| Band | Taxable Income | Rate |
|---|---|---|
| Starter Rate | £12,501-£14,549 | 19% |
| Basic Rate | £14,550-£24,944 | 20% |
| Intermediate Rate | £24,945-£43,430 | 21% |
| Higher Rate | £43,431-£150,000 | 41% |
| Top Rate | Over £150,000 | 46% |
Our calculator uses the England/Wales/Northern Ireland rates. Scottish taxpayers should adjust their calculations accordingly or use HMRC’s Scottish rate tools.

Expert Tips for Optimizing Your 2019-20 Tax Position
While the tax year has passed, understanding these strategies can help with amendments and future planning:

Interactive FAQ: 2019-20 Income Tax Questions
What was the emergency tax code for 2019-20 and how did it affect calculations?
The emergency tax code for 2019-20 was 1250L, which was actually the standard code for most people. However, emergency codes might appear as 1250L W1, 1250L M1, or 1250L X, indicating:
- W1/M1: Week 1/Month 1 basis (no cumulative calculation)
- X: Used when HMRC doesn’t have details of other income
These codes would tax all income above the weekly/monthly personal allowance (£240/week or £1,042/month) at basic rate, potentially leading to overpayment that would be refunded after HMRC received your correct details.
If you were on an emergency code, you should have contacted HMRC with your P45 or employment details to get the correct code. Any overpaid tax would be refunded through your tax return or adjusted in your tax code.
How did the marriage allowance work in 2019-20 and who was eligible?
The marriage allowance for 2019-20 allowed a spouse or civil partner to transfer 10% of their personal allowance (£1,250) to their partner, provided:
- The transferor’s income was £12,500 or less
- The recipient was a basic rate taxpayer (earning between £12,501 and £50,000)
- Both partners were born after 5 April 1935
This could save the couple up to £250 in tax for the year. The transfer had to be claimed through HMRC’s online service or by phone. Importantly:
- It couldn’t be backdated beyond the current tax year
- If circumstances changed (e.g., income increased), the allowance could be withdrawn
- The transferor’s personal allowance would be reduced by £1,250
For 2019-20, over 2.1 million couples benefited from the marriage allowance, with an average saving of £230.
What were the key differences between Scottish and rest-of-UK income tax in 2019-20?
Scottish taxpayers faced a different income tax structure in 2019-20, with five rates instead of three:
| Band | Scotland | Rest of UK |
|---|---|---|
| Personal Allowance | £12,500 @ 0% | £12,500 @ 0% |
| Starter Rate | £12,501-£14,549 @ 19% | N/A |
| Basic Rate | £14,550-£24,944 @ 20% | £12,501-£50,000 @ 20% |
| Intermediate Rate | £24,945-£43,430 @ 21% | N/A |
| Higher Rate | £43,431-£150,000 @ 41% | £50,001-£150,000 @ 40% |
| Top Rate | Over £150,000 @ 46% | Over £150,000 @ 45% |
Key implications:
- Scottish taxpayers paid more tax on incomes between £24,945 and £43,430 (21% vs 20%)
- Higher earners in Scotland paid 1% more on income between £43,431 and £150,000
- The top rate threshold was the same (£150,000) but Scottish taxpayers paid 1% more
- National Insurance rates remained aligned across the UK
Scottish taxpayers should use HMRC’s Scottish income tax calculator for precise calculations.
How were dividend taxes calculated in 2019-20 and what was the tax-free allowance?
For 2019-20, dividend taxation worked as follows:
- Dividend Allowance: £2,000 tax-free (reduced from £5,000 in 2017-18)
- Tax Rates:
- Basic rate: 7.5% (on dividends above allowance within basic rate band)
- Higher rate: 32.5% (on dividends within higher rate band)
- Additional rate: 38.1% (on dividends above £150,000)
- Calculation Method:
- Add dividends to other income to determine tax band
- Apply the dividend allowance to the first £2,000 of dividends
- Tax remaining dividends at the appropriate rate based on total income
Example: Someone with £45,000 salary and £5,000 dividends:
- First £2,000 dividends = tax-free
- Remaining £3,000 taxed at 7.5% = £225 tax
- Total tax on dividends = £225
Dividends were paid with a 10% tax credit in 2019-20, meaning no tax was due if dividends fell within the personal allowance or dividend allowance.
What were the deadlines for amending 2019-20 tax returns and paying any additional tax?
The key deadlines for 2019-20 tax returns were:
- Online Filing Deadline: 31 January 2021
- Paper Filing Deadline: 31 October 2020
- Payment Deadline: 31 January 2021 (for balancing payment and first payment on account)
- Second Payment on Account: 31 July 2021
For amendments:
- You had until 31 January 2022 to amend your 2019-20 tax return
- Amendments could be made online through your HMRC account or by submitting a corrected paper return
- If you discovered an error after this date, you would need to write to HMRC with full details
Late filing penalties:
- 1 day late: £100 penalty
- 3 months late: Additional £10 per day (up to £900)
- 6 months late: Further penalty of 5% of tax due or £300 (whichever is greater)
- 12 months late: Another 5% penalty
Interest was charged on late payments at 2.6% (from 31 January 2021) plus potential late payment penalties of 5% of tax unpaid at 30 days, 6 months, and 12 months.
How did the high income child benefit charge work in 2019-20?
The High Income Child Benefit Charge (HICBC) applied if:
- You or your partner received Child Benefit
- Your individual income exceeded £50,000
For 2019-20:
- The charge was 1% of Child Benefit for every £100 of income over £50,000
- At £60,000, the charge equaled the full Child Benefit received
- The charge was collected through Self Assessment
Example: Someone earning £55,000 with one child (Child Benefit = £1,076):
- Income over £50,000 = £5,000
- Charge = (£5,000/£100) × 1% × £1,076 = £538
- Effective Child Benefit received = £1,076 – £538 = £538
Options to manage the charge:
- Opt out of receiving Child Benefit (but still register to get National Insurance credits)
- Reduce income below £50,000 through pension contributions or charitable donations
- Share income with a lower-earning partner if possible
Over 500,000 families were affected by HICBC in 2019-20, with an average charge of £1,300.
What records should I have kept for my 2019-20 tax return?

For Employed Individuals:
- P60 from your employer (showing total pay and tax deducted)
