OpenWhat is in here, and how current it is
These are the reference tools we use ourselves. The rates and allowances tables carry the current and prior tax year side by side, because most questions in practice are about which year a figure belongs to. The calculators give an estimate you can plan against, not a filing position. The tax calendar lists the statutory deadlines for individuals, businesses and employers, and the factsheet library covers the topics that come up often enough to be worth writing down properly.
Everything here follows HMRC. Where a figure is set by legislation we take it from the relevant GOV.UK page and link to it, so you can check the source rather than take our word for it. Rates are reviewed at each Budget and Spring Statement, and the tables are updated when the new figures are confirmed — not when they are announced, since announced measures change before they take effect more often than people expect.
None of it is advice. A rate table cannot know that your allowance is tapering, that two reliefs interact, or that taking income in a different order would change the total. That is the part we do. Get in touch if you want the answer rather than the figure.
Frequently asked
Are these figures up to date?
The rate tables are updated for the current tax year, and each page states the year it is showing. The explanatory content is written to be principle-based rather than dated, so it does not quietly go stale between Budgets. If you find something that has moved, tell us and we will fix it.
Can I use the calculators for a real decision?
Use them to get the shape of an answer, not to make the decision. They apply the published rates to the figures you enter and know nothing else about you — no tapering allowance, no interaction with another relief, no reason the timing might change the total. For anything that matters, bring us the number and we will tell you what it means for your position.
Do I have to be a client to use this?
No. All of it is free and none of it asks for an email address. We publish it because the questions come up constantly, and because a practice that will not explain the basics is not one worth hiring.
Which of these should I look at first?
If you are trying to work out what something will cost, start with the calculators. If you want to check a rate or a threshold, the tax rates section. If you are trying not to miss something, the tax calendar. If you want to understand a subject properly, the factsheets.
Beyond the tools
Numbers are easy. Deciding what to do with them is not.
The calculators and tables here will get you an estimate. If you want the decision behind it, that is what we are for.
