Company formation in Harrow Road — from £49, fixed.

Online Self Assessment returns are due by 31 January, along with any balancing payment — and HMRC's £100 penalty applies the moment the deadline passes, even if you owe nothing. Most Harrow Road clients who come to us in January still file on time; the records just need to arrive before the last week.

From April 2026, self-employed people and landlords with qualifying income over £50,000 move onto Making Tax Digital for Income Tax: digital records and quarterly updates to HMRC, not one annual return. The year before is the right time to get bookkeeping into shape.

A good accountant should be able to tell you, in plain English, what they'll do, when, and for exactly how much. Vagueness on any of the three is the tell. Everything else — size of firm, fancy office, distance from Harrow Road — is decoration.

Timing disposals across tax years, using losses properly, and the spousal transfer rules can all legitimately reduce capital gains bills — but only before the sale. CGT planning after completion is just arithmetic.

Company deadlines run off your accounting year end, not the tax year: corporation tax is payable nine months and one day after year end, and the CT600 return is due twelve months after. Confusingly, the payment is due before the return — a sequencing quirk that catches new directors.

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.

The businesses that struggle with tax bills rarely have a tax problem; they have a timing problem. Knowing the bill in September instead of January — which filing early gives you for free — is the difference between planning and scrambling.

Scam "HMRC" messages outnumber real ones — HMRC doesn't demand payment by gift card or threaten arrest by text. Real letters have reference numbers that we can verify directly with HMRC before anyone responds.
