Scottish Income Tax Calculator
Estimate self-employed Income Tax in Scotland - 2026/27
Working out your tax bill for self-employment in Scotland
If you’re self-employed and live in Scotland, you’ll pay Scottish Income Tax rates rather than those that apply elsewhere in the UK – but your National Insurance contributions are worked out in the same way.
To estimate how much tax you owe as a Scottish taxpayer, enter your total self-employed earnings, any allowable business expenses, and any other income you received in the same tax year.
Our free calculator will apply the current Scottish Income Tax bands and rates to work out what you owe and estimate your Class 4 National Insurance contributions, helping you prepare for your tax bill.

How much tax you pay in Scotland
The amount of tax you pay depends on how much taxable income you get during the tax year. Scotland has its own tax bands and rates, so your bill is likely to be different to someone earning the same amount elsewhere in the UK.
The Scottish tax rates will apply to earnings, pensions and most other taxable income, but dividends, savings interest and National Insurance are charged using the UK-wide rates.
Scottish taxpayers are still entitled to the tax-free personal allowance, but like everyone in the UK you’ll only get the £12,570 if your income is below £100,000. Above that the allowance is gradually withdrawn, and it disappears completely once you earn £125,140 upwards.
Is National Insurance the same in Scotland?
Although Scotland uses different Income Tax rates and thresholds, self-employed people still pay Class 4 National Insurance using the same rates as the rest of the UK.
The amount of National Insurance you pay comes down to your profits; the more you make, the more you’ll pay. Class 4 NI kicks in once your profits go over the £12,570 Lower Profits Limit, charged at 6% of everything above that threshold up to the £50,270 Upper Profits Limit. Any earnings above that are subject to NI at a rate of 2%.
You’ll normally need to register as self-employed if you earn more than the £1,000 Trading Allowance from self-employment in a tax year, regardless of where in the UK you live. If you need to register, make sure everything is set up by 5th October in your second tax year. For example, if you start trading in 2025/26 (6th April 2025 - 5th April 2026), you’ll need to register no later than 5th October 2026.
Income Tax is partly devolved to the Scottish Government, which sets its own rates and bands for earnings and pensions. This means Scotland has more bands than the rest of the UK, and higher earners in particular can pay a noticeably different amount of Income Tax. National Insurance, however, is set by the UK Government and is the same wherever you live in the UK.
Scottish taxpayers are subject to the UK-wide tax reporting deadlines, so the last date to submit depends on how you file. Paper returns for the 2025/26 tax year are due by 31st October 2026, while online returns have a little longer and are due by 31st January 2027. The payment deadline is 31st January 2027 for everyone.
You may be able to ask HMRC for a Time to Pay arrangement which spreads your bill over monthly instalments, even if the deadline has already passed. Contact HMRC as soon as possible if you think you’ll need this.
Claiming all the business expenses and allowances you’re entitled to will help reduce your taxable profit. Because Scottish bands and rates differ from the rest of the UK, it’s also worth checking whether your business structure is still the most tax-efficient option for you.
