Key insights
- The official gov.uk calculator is the most reliable source for PAYE employees, but it lacks guidance for self-employed individuals.
- Many users are confused about whether National Insurance applies to dividend income; it does not – only Income Tax on dividends above the allowance.
- The personal allowance for 2025/26 remains frozen at £12,570, pushing more people into higher tax brackets as wages rise.
- Self-employed users need separate estimates for Class 2 and Class 4 NI, which are calculated differently from employee Class 1.
- Pension contributions directly reduce taxable income, affecting both Income Tax and NI, but NI relief is only automatic for workplace pensions.

|---|---|
| Personal Allowance | £12,570 |
| Basic Rate (20%) band | £12,571 – £50,270 |
| Higher Rate (40%) band | £50,271 – £125,140 |
| Additional Rate (45%) | Over £125,140 |
| Employee NI (Class 1) main rate | 8% on earnings between £12,570 and £50,270, then 2% above |
| Self-employed NI (Class 2) | £3.45 per week (if profits >£12,570) |

The GOV.UK estimate service is the official starting point for most employees. It covers PAYE workers, calculates Income Tax and NI, and includes pension contributions and student loan repayments. For the 2026/27 tax year, Which? confirms its calculator can show Income Tax and NI for both 2025/26 and 2026/27, allowing side-by-side comparison.
What Is My Take-Home Pay After Tax and National Insurance?
Your take-home pay depends on your gross salary, tax code, NI category, and any additional deductions. For 2026/27, a typical monthly net pay after income tax and NI for a £30,000 salary is approximately £2,093. At £50,000, that figure rises to around £3,293 per month, according to salary table estimates.
How do pension contributions affect my take-home pay?
Pension contributions reduce your taxable income, lowering both Income Tax and NI. The GOV.UK estimate service and the MoneySavingExpert calculator both include pension inputs, with the latter also factoring in student loan repayments.
What is the net pay after student loan repayments?
Student loan repayments are deducted from your salary after tax and NI. The GOV.UK service and several calculators, including those from The Salary Calculator and MoneySavingExpert, include this deduction. For accurate figures, enter your loan plan type and repayment threshold.
How to Calculate Tax and National Insurance if You Are Self-Employed
Self-employed individuals pay Class 2 and Class 4 National Insurance, which are calculated differently from employee Class 1. Class 2 is a flat weekly amount of £3.45 for profits above £12,570. Class 4 is 9% on profits between £12,570 and £50,270, and 2% on profits above that.
The StepChange self-employed income calculator is a dedicated tool for estimating your total tax bill, including both NI classes. It also accounts for allowable expenses, which can significantly reduce your taxable profit.
How do I estimate my self assessment tax bill?
Use the StepChange Self-Employed Income Calculator to estimate your total liability. Remember that you must file a self-assessment return each year, with the online deadline on 31 January following the end of the tax year.
Are there any allowances for self-employed expenses?
Yes. Allowable expenses such as office costs, travel, and equipment can reduce your taxable profit. The calculators do not automatically include these – you must enter your net profit after deducting allowable expenses.
What Are the Latest Income Tax Bands, Personal Allowances, and NI Rates?
For 2026/27, the standard income tax bands for England, Wales, and Northern Ireland are: 20% basic rate on taxable income from £12,571 to £50,270; 40% higher rate from £50,271 to £125,140; and 45% additional rate above £125,140. The personal allowance remains at £12,570 for most people.
How much National Insurance do I pay?
For employees, Class 1 NI is 0% below £242/week or £12,570/year, 8% between £242 and £967/week (or £12,570 and £50,270/year), and 2% above that. These rates apply for 2026/27.
How does the Scottish income tax differ?
Scotland uses a six-band system for 2026/27. The Scottish basic rate is 20% on taxable income from £16,538 to £29,526; an intermediate rate of 21% applies from £29,527 to £43,662; a higher rate of 42% from £43,663 to £75,000; and a top rate of 48% applies above £125,140.
The Scottish rates apply only to non-savings, non-dividend income. Dividends and savings income are taxed at UK-wide rates regardless of where you live.
How to Calculate Tax on Shares and Other Investment Income
Dividends are subject to Income Tax but not National Insurance. From 2025/26, the dividend allowance is £500. Any dividends above this amount are taxed at 8.75% (basic rate), 33.75% (higher rate), or 39.35% (additional rate). Capital Gains Tax on shares is calculated separately and does not attract NI.
Do I pay National Insurance on dividends?
No. National Insurance is not charged on dividend income, regardless of the amount. Only Income Tax applies above the allowance.
What is the dividend allowance?
For 2025/26, the dividend allowance is £500. This means the first £500 of dividend income is tax-free. Above that, dividends are taxed at your marginal rate.
Many people assume that dividends from shares held in a general investment account are tax-free. They are not – only dividends within an ISA wrapper are tax-free. Always check your total dividend income against the allowance.

What Is Certain and What Remains Unclear About Your Tax Calculation?
| Established Information | Information That Remains Unclear |
|---|---|
| Income tax bands and personal allowance for 2025/26 are confirmed (Finance Act 2024). | Future changes after 2025/26 (e.g., possible NI unification or allowance increases) depend on Government budgets. |
| National Insurance main rates for employees and self-employed are legislated. | Your actual tax code may vary due to benefits, under/overpayments, or multiple incomes – always check your P45/P60. |
| The official gov.uk calculator provides a correct estimate based on your inputs. | Self-employed profits can be complex – the calculator provides an estimate; final liability may differ after allowable expenses. |
Why Accurate Tax Calculation Matters and How to Choose the Right Tool
Knowing your net pay helps with budgeting, pension planning, and avoiding underpayment penalties. The 2025/26 year sees frozen allowances and reduced NI rates since January 2024, affecting take-home pay.
For most employees, the GOV.UK estimate service or MoneyHelper Salary Calculator are sufficient. Self-employed users should use the StepChange tool or a dedicated self-employment calculator. No single calculator covers all scenarios (e.g., multiple incomes plus investments). Common pitfalls include forgetting student loan deductions, misclassifying income type, overlooking the marriage allowance, or assuming NI applies to all income sources.
