Read guideFrequently Asked Questions
Common questions about tax & compliance.
For England, Wales, and Northern Ireland: 20% basic rate on income from £12,571 to £50,270; 40% higher rate from £50,271 to £125,140; 45% additional rate above £125,140. The personal allowance is £12,570 and begins to taper for incomes over £100,000. Scotland has different rates with 6 bands ranging from 19% (starter) to 48% (top rate).
Companies with profits between £50,000 and £250,000 pay a blended rate between 19% (small profits rate) and 25% (main rate), calculated using the marginal relief formula. The effective marginal rate in the relief band is 26.5%. The thresholds are divided by the number of associated companies, which can significantly affect the calculation.
The VAT registration threshold for 2026/27 is £90,000. If your taxable turnover in any rolling 12-month period exceeds this, you must register for VAT within 30 days. You can also register voluntarily below this threshold, which may be beneficial if you have significant VAT-able purchases.
Under the Construction Industry Scheme: registered subcontractors have 20% deducted from labour payments; unregistered subcontractors have 30% deducted; subcontractors with gross payment status have 0% deducted. These deductions are offset against the subcontractor's tax and NI liability when they file their self assessment.
For residential property, CGT must be reported and paid within 60 days of completion via HMRC's online service. For other assets (shares, business assets), CGT is reported via self assessment and paid by 31 January following the tax year end. The annual exempt amount is £3,000 for 2026/27. Rates are 18%/24% for all chargeable assets depending on whether you're a basic or higher rate taxpayer.
All calculations use official HMRC rates for 2026/27, updated April 2026. Results are estimates for guidance only - not financial advice. Our methodology · Disclaimer
