UK 2026/27 tax year · Updated 2026-06-10
Whether you run your own practice or work in industry, accountants need quick, dependable figures across the full UK tax landscape. These calculators cover the day-to-day work of preparing accounts and advising clients: corporation tax on company profits, VAT under the £90,000 registration threshold, the perennial dividend-versus-salary question for owner-managed companies, and self-assessment for sole traders and partnerships. With Making Tax Digital for Income Tax (MTD ITSA) arriving from April 2026 for those earning over £50,000, more clients will need clear projections of their quarterly position. Every result reflects the current 2025/26 rates and allowances — the 19% and 25% corporation tax bands with marginal relief, the £500 dividend allowance, Class 2 and Class 4 National Insurance, and the personal allowance taper above £100,000. Use them for fast client estimates, sense-checking software output, or illustrating the impact of a remuneration strategy before you commit it to a tax return.
