Tithing in the UK — gross, net, and Gift Aid
A tithe is 10% of your income given to your church. In the UK the practical questions are which base to use — gross salary or take-home pay after Income Tax and National Insurance — and how Gift Aid fits in.
A worked example
On a £30,000 gross salary:
- Tithe on gross: £3,000/year — £250/month or about £57.69/week
- With Gift Aid: your church reclaims 25p per £1 from HMRC, so that £250/month is worth £312.50/month to the church — at no extra cost to you
To use Gift Aid, complete a one-time declaration with your church and make sure you pay enough UK tax to cover the reclaim. Many UK churches make this automatic when you set up recurring online giving. If your church needs software that tracks Gift Aid declarations and generates HMRC claims, see our Gift Aid claim software guide and MosesTab for UK churches.
Frequently asked questions
How do I calculate my tithe in the UK?
Take 10% of your income — most UK Christians use either gross salary (before Income Tax and National Insurance) or net take-home pay. On a £30,000 gross salary, a 10% tithe is £3,000 per year, or £250 per month. Enter your salary in the calculator above to see weekly, monthly, and annual breakdowns in pounds.
Should I tithe on gross or net salary in the UK?
Scripture doesn't specify a payroll rule, and UK churches teach both approaches. Tithing on gross (before Income Tax, National Insurance, and pension contributions) treats the full amount you earned as the base; tithing on net treats what actually reaches your account as the base. Choose the approach you can give consistently and cheerfully — the calculator supports both.
How does Gift Aid work with tithing?
If you're a UK taxpayer, Gift Aid lets your church reclaim 25p from HMRC for every £1 you give — so a £250 monthly tithe becomes £312.50 for your church at no extra cost to you. You simply complete a Gift Aid declaration with your church once. Higher-rate taxpayers can additionally claim relief on the difference through Self Assessment. Confirm specifics with HMRC or a tax adviser.
Is tithing tax deductible in the UK?
The UK doesn't use the US-style charitable deduction. Instead, Gift Aid handles the tax benefit: the church reclaims basic-rate tax on your donation, and higher/additional-rate taxpayers can claim the remaining relief via Self Assessment or their tax code. Donations must go to a registered charity (most UK churches are) and you must pay enough UK tax to cover the reclaim.
What is a tithe on typical UK salaries?
A 10% tithe is £2,400/year (£200/month) on a £24,000 salary, £3,000/year (£250/month) on £30,000, £4,500/year (£375/month) on £45,000, and £6,000/year (£500/month) on £60,000 — all calculated on gross. Use the calculator to adjust for net pay or a different percentage.
