FAQ

Common questions

Do I need to register as self-employed?

Yes — if you're earning self-employed income, you need to register with HMRC and get a UTR (Unique Taxpayer Reference). We can talk you through it.

What's the Self Assessment deadline?

Online returns are due by 31 January, with a second "payment on account" often due 31 July. We track both for you.

What expenses can I claim?

It depends on your work — things like equipment, mileage, and a portion of home costs are commonly allowable. We'll go through what applies to you.

I also run a limited company — can you help?

Yes — company work is routed directly to our IFA-accredited accountant, who handles it personally. Just let us know when you get in touch.
