For Tax Comparison Tool UK 2026/27, the calculation period is 6 April 2026 to 5 April 2027. The model concentrates on regional employment-tax comparison, with the key mechanics being the same salary under two tax systems. Treat the output as a transparent estimate rather than a replacement for HMRC or payroll records.

How to Use the Tax Comparison Tool UK 2026/27

Holding salary constant isolates the regional Income Tax difference rather than mixing it with a different pension or student-loan assumption. A fair regional comparison changes one tax system at a time. Keeping salary and NI assumptions fixed makes the Scottish-versus-rest-of-UK difference understandable.

National Insurance is calculated on the same annual salary in both scenarios. Savings and dividends are not part of this employment-income comparison.

2026/27 Personal Allowance

The £12,570 Personal Allowance is not guaranteed at every income level. For 2026/27 it starts reducing after £100,000 of adjusted net income at a one-for-two rate. By £125,140 the standard amount is nil, which is particularly important when modelling regional employment-tax comparison. In the context of Tax Comparison Tool UK 2026/27, the number only matters when it changes regional tax comparison. This page therefore ties the rule back to holding salary constant while changing the employment-income system, which is the decision path most useful for workers comparing Scotland with the rest of the UK.

Income Tax Rates Used in the Model

The rest-of-UK side of Tax Comparison Tool UK 2026/27 follows the published 2026/27 PAYE bands: 20% basic, 40% higher and 45% additional. Because the bands apply to taxable income after allowances, the difference is driven by devolved scottish bands on non-savings employment income; ni assumptions are kept consistent so they do not obscure that comparison. can shift the amount falling into each rate.

Where a regional comparison is useful for Tax Comparison Tool UK 2026/27, Scotland is treated as a distinct employment-income system rather than a minor adjustment. The difference is driven by devolved Scottish bands on non-savings employment income; NI assumptions are kept consistent so they do not obscure that comparison. Savings and dividend taxation are separate questions, so they are not folded into this salary comparison.

National Insurance and Other Deductions

National Insurance is handled separately from regional employment-tax comparison. On salary pages that need it, the standard category-A planning model charges 8% above the annualised Primary Threshold to the Upper Earnings Limit and 2% above that. Pages that isolate dividends, CGT, allowance or pension relief do not invent an NI deduction. For this calculator, the next step is not to apply every tax rule on the site. It is to connect the figure with regional tax comparison, using holding salary constant while changing the employment-income system. That narrower scope is intentional for workers comparing Scotland with the rest of the UK.

Student loans can change cash take-home without changing the Income Tax liability. The 2026/27 model uses Plan 1 £26,900, Plan 2 £29,385, Plan 4 £33,795 and Plan 5 £25,000 at 9% above threshold, plus postgraduate £21,000 at 6%. The reason it appears on Tax Comparison Tool UK 2026/27 is page-specific: regional tax comparison can be misunderstood if holding salary constant while changing the employment-income system is left implicit. The wording here is aimed at workers comparing Scotland with the rest of the UK and the result should be read on that basis.

Who Should Use the Tax Comparison Tool UK 2026/27

A worker considering a move or comparing offers in Scotland and elsewhere can use this page to isolate the tax-system effect without changing gross pay.

The calculation centres on the same salary under two tax systems. The difference is driven by devolved Scottish bands on non-savings employment income; NI assumptions are kept consistent so they do not obscure that comparison. Keeping those drivers explicit makes it possible to rerun the same scenario after a pay rise, code change or new tax year without guessing which assumption moved.

Use the result to understand regional employment-tax comparison, then move to a specialist page if another income source or deduction becomes material. A page that tries to solve salary, dividends, capital gains, benefits, pensions and multiple jobs in one default calculation would hide more assumptions than it explains. BritTaxCalc treats this differently on Tax Comparison Tool UK 2026/27 because the core output is regional tax comparison. By focusing on holding salary constant while changing the employment-income system, the page avoids suggesting that the same rule has identical importance on every calculator.
