Trading Allowance Checker UK 2026/27

Trading Allowance Checker UK 2026/27 is a spreadsheet for people with a side hustle.

Type in each side hustle's income and costs by month, and the Check sheet tells you in one sentence where you stand against the £1,000 trading allowance.

• Under £1,000: nothing to tell HMRC for this income.
• Over £1,000: you need to register for Self Assessment. The sheet shows your taxable profit with the allowance and with actual expenses, and which is lower.

It also has:

• Three exclusion questions from gov.uk (a company you control, a partnership, your employer) that switch the allowance off.
• A note on selling your own things, using gov.uk's wording.
• A platform count, for Vinted, eBay, Etsy and others, against the reporting limits of 30 sales or about 2,000 euros (about £1,700) a calendar year.
• Key dates: register by 5 October after the tax year, return and payment by 31 January.

Up to 10 side hustles. An example copy (invented figures) and a blank copy. Works in Excel 2016 or later and in Google Sheets. No macros. Everything except the yellow cells is locked, with no password.

Limits and dates come from gov.uk, with the page each came from, checked on 2026-11-06. It does not send anything to HMRC. It is not tax advice.
