In the UK (but probably nowhere else in the civilized world) tax years run from 6 April and end the following 5 April. So the current tax year 2021/22 started on 6 April 2021 and will end on 5 April 2022.

This table does not include the special tax rates that apply to savings income and dividends.

The NI and VAT rates apply throughout the UK. However the income tax rates apply on in England, Wales and Northern Ireland. Scotland has a more complex system of 5 income tax bands instead of 3.

Tax jargon buster

Allowable expenses

Business expenses that you’re allowed to take away from your income before your income tax is worked out.

Customs & Excise

The arm of HMRC which deals with VAT as well as custom duties

HM Revenue & Customs

Aka the taxman. Formed in 2005 from the amalgamation of HM Customs & Excise with the Inland Revenue.

Income tax

The main tax on income. The more you earn the more you pay.

Inland Revenue

The arm of HMRC which deals with Income Tax, NIC and Tax Returns.


An Inland Revenue Press Release about stopping people who are really employed from setting up limited companies so as to get the tax advantages of self- employment. The computer industry is obsessed with IR35. But it is of no relevance whatsoever to independent escorts.

National Insurance (NIC)

Really a form of income tax though the government likes to pretend it’s an insurance you pay in return for getting various state benefits including the state retirement pension

Overlap relief

If you do your business accounts each year to a date other than 31 March (strictly 5 April) then some of your income will get taxed twice in the first 2 years of your business. But when the business ends the overlap period will be taken off your final year’s profits.

Tax avoidance

This is legal – arranging your affairs so you pay less tax

Tax evasion

And this is not legal – usually involves lying or cheating


The total money you receive from your clients. Basically income before subtracting any of your expenses.


Value Added Tax – a nasty European inspired tax

VAT Input tax

The VAT you pay on the goods and services you buy into your business. If you buy £120.00 of massage oils then £20.00 of it is VAT input tax which you could get back if you were VAT registered and the oils were all for business use.

VAT Output tax

If you’re VAT registered this is the VAT you charge on services you supply out to your clients. The client pays you the tax which you effectively collect on behalf of the government. NB Nothing to do with incall and outcall!
