When Should You Register with HMRC?

You must register by 5th October in your business's second tax year. Even if you're earning below the tax threshold, registration is still required. HMRC's online service makes the process quick and straightforward.


Once registered, you'll receive your Unique Taxpayer Reference (UTR) number. Missing the deadline can result in penalty charges, so don't delay. Keep your confirmation documents somewhere safe as you'll need them later.

Which Expenses Can You Claim as a Personal Trainer?

Don't forget about marketing materials and website maintenance fees. Professional development courses help you grow while lowering your tax bill through tax-deductible training expenses. Working from home means you can claim a portion of household bills.
