Accountants in Hayes End

Selling online, freelancing on the side, renting out equipment — each can be a "trade" in HMRC's eyes once it's done with a profit motive. The good news: registering is straightforward, expenses become claimable, and done early it's a non-event.

The expenses rule is "wholly and exclusively" for the trade — which covers more than most people claim (proportionate home-working costs, business mileage, software subscriptions) and less than some hope (client entertaining, everyday clothing). Knowing the line is where the savings live.

Auto-enrolment applies from the first eligible employee: assess, enrol, contribute, declare. The Pensions Regulator does check, and the fines for ignoring it are out of proportion to how simple compliance actually is.

Limited companies in CIS reclaim differently to sole traders — through payroll or the company tax return rather than Self Assessment. Plenty of construction companies sit on refundable deductions without realising; a quick review of the CIS position often pays for itself immediately.

Compliance checks are usually specific: one return, one figure, one question. Answered promptly and with evidence, most close quickly. The expensive enquiries are the ones that started as unanswered letters.

Inside-IR35 and outside-IR35 engagements need different setups — sometimes umbrella, sometimes the company, sometimes both across a year. Contractors who plan this per-engagement keep more and worry less.

If your last Self Assessment bill was over £1,000, HMRC usually asks for next year's tax in advance — half on 31 January, half on 31 July. It's the number-one cause of "why is my bill double?" calls, and it's manageable: if your income has dropped, the payments can be reduced with a claim.

UK residential property sales have their own regime: report and pay within 60 days of completion, separately from Self Assessment. Other gains report annually. Mixing up the two timetables is a common and expensive mistake.
