Tax Calculator UK 2026

About

Estimate UK Income Tax, National Insurance, Stamp Duty, dividend tax, self-employed NI, student loan repayments, and Marriage Allowance for the 2026/27 tax year — all in one fast, on-device calculator. Built for PAYE employees, contractors, landlords, and anyone planning a salary change, a property purchase, or a side hustle. SIX CALCULATORS, ONE APP - Income Tax and take-home pay: gross-to-net for England, Scotland and Wales, with Scottish PAYE bands handled separately. - Stamp Duty: SDLT for England and Northern Ireland, LBTT for Scotland, LTT for Wales — including first-time buyer relief and the additional-property surcharge. - Dividend Tax: combine salary and dividends to see your true marginal rate after the dividend allowance. - Self-Employed National Insurance: Class 4 estimates for sole traders and side-hustle income, with Class 2 shown as zero under the current app assumptions. - Student Loan Repayments: Plan 1, Plan 2, Plan 4 (Scotland), Plan 5, and Postgraduate loans — modelled against your projected salary. - Marriage Allowance: check eligibility and the annual transfer benefit for couples where one partner earns under the personal allowance. WHEN TO USE IT - Negotiating a pay rise: see exactly what an extra £5k means after tax, NI and student loan. - Comparing two job offers: side-by-side scenarios show take-home, pension impact, and student-loan drag. - Buying a home: model SDLT/LBTT/LTT for first homes, second properties and buy-to-let in seconds. - Going self-employed: estimate self-employed NI on top of Income Tax before you set your day rate. - Filing planning: sanity-check your numbers before Self Assessment in January. PREMIUM AND ANNUAL PACK Two optional in-app purchases, both one-time (no auto-renewal): - Premium (Lifetime): a one-off unlock that adds side-by-side scenario comparison for salary and property, removes ads, includes future tax-year table updates, and keeps unlimited saved scenarios — forever. - Annual Update Pack (Tax Year Pack): a one-time purchase for the current 2026/27 tax-year tables plus unlimited saved scenarios for that year. It expires after one year and does NOT auto-renew. The free version keeps the core calculators and up to three saved scenarios, supported by Google banner ads.
