Self Assessment accountant

Your Unique Taxpayer Reference — the 10-digit number HMRC issues when you register for Self Assessment. Lifelong, and needed for every return.

Advance payments toward next year's tax, due 31 January and 31 July, triggered once your bill passes £1,000. The first year they apply effectively bills 150% at once.

The main Self Assessment return form. Supplementary pages bolt on for employment, self-employment, property, capital gains and foreign income.

The difference between what your payments on account covered and what the year's tax actually was — settled each 31 January.

UK residential property gains must be reported and the tax paid within 60 days of completion — separate from and earlier than Self Assessment.

The relief (formerly Entrepreneurs' Relief) taxing qualifying business disposals at 10% up to a lifetime limit — conditions apply for at least two years before sale.

The slice of gains each person can realise tax-free per year — now small, which makes timing disposals across tax years worth planning.

For a straightforward return with one income source, yes — preparation, supplementary pages, filing and deadline management included. Rental income makes it £169, capital gains £199, late-return rescue £179. Whichever applies is confirmed in writing before we start, and that's the number on the invoice.

Three common reasons: your time is worth more than the fee, your situation stopped being simple (property, dividends, CGT, foreign income), or you've been stung before — a missed relief, a wrong payment on account, a penalty. We also spot the things software doesn't ask about.

Straightforward returns usually go to you for approval within 2–3 working days, faster in a deadline emergency. The bottleneck is almost always missing records — which is why chasing them is part of the service, not your job.

Preparation and online filing of your full SA100 return, including the supplementary pages your situation needs. If your return is more complex — rental income, capital gains — the packages above show the fixed price, and we confirm it in writing before starting.

Yes. Late returns are common and fixable: we prepare and file the outstanding return quickly, and where there's a reasonable excuse we help you appeal penalties. The sooner it's filed, the sooner the penalties stop growing.

There's no Companies House filing for sole traders, but you must keep records supporting your Self Assessment — and proper accounts almost always save more tax than they cost, because expenses stop slipping through the cracks.

Anything wholly and exclusively for the business: materials, tools, mileage or vehicle costs, phone, insurance, home-office use, software, professional fees and more. Our job is claiming everything legitimate — clients are usually surprised by what they'd been missing.

Under Section 24 you can't deduct mortgage interest from rental profits — instead you get a 20% tax credit. Higher-rate landlords pay noticeably more than under the old rules, which is why the sums (and the company question) deserve proper attention.

Sometimes. Companies deduct interest in full and pay corporation tax rates, but you face costs extracting profits and potentially CGT/SDLT moving existing properties in. We'll run your actual numbers — the honest answer is 'it depends', and we'll show you on what.

If you sell a UK residential property at a gain, you must file a CGT return and pay the tax within 60 days of completion — separate from, and much earlier than, Self Assessment. Penalties apply immediately after day 60. It's the most-missed deadline in UK tax.

For most assets 18% or 24% depending on your income band. Business asset disposal relief can cut qualifying business sales to 14%. Your other income determines the split — which is exactly what we calculate.
