Accountants in Great Common

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.

Since Section 24, individual landlords can't deduct mortgage interest as an expense — it's a 20% tax credit instead, which pushes some higher-rate landlords into surprising bills. Whether to hold property personally or through a company is now a genuine question with genuine trade-offs.

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.

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.

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.

Register with HMRC by the 5 October after your first tax year of trading, open a separate business account, and put a fixed slice of every payment aside for tax. Do those three things and your first January will be boring — the good kind.

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.
