UK Tax Resources & Official Guidance

Find calculators, tax explanations and official guidance for the 2026/27 tax year. Use the linked HMRC and government pages for eligibility rules, forms and filing obligations.

Where should I verify my tax position?

Start with GOV.UK for UK Income Tax, National Insurance, dividends and CGT. For property purchases use the authority for the property location: HMRC for England/NI, Revenue Scotland for LBTT and the Welsh Revenue Authority for LTT. General guides do not replace advice about your own circumstances.
