Accountants in Lydiard Green

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.

If you contract through your own limited company, IR35 asks whether you'd be an employee without it. For medium and large clients, the status decision is theirs; for small clients, it's still yours — and getting it wrong in either direction costs money.

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.

HMRC receives data directly from online platforms about sellers' income. If a side hustle has grown past the £1,000 trading allowance, coming forward first is always cheaper than being written to — penalties scale with how the disclosure starts.

Receipts win arguments. HMRC doesn't demand a shoebox of paper any more — photos in an app are fine — but every deduction needs evidence behind it. A ten-minute weekly habit beats a January archaeology dig, every time.

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.

Payments on account catch people out because the first year effectively bills you one-and-a-half years of tax at once. Knowing that in advance changes how you save through the year — and if profits fall, we can apply to reduce the July payment rather than lending HMRC money interest-free.

Directors paying themselves a salary still need a PAYE scheme and RTI submissions, even in a one-person company. It's a five-minute monthly task with software — and a recurring penalty generator without it.
