Capital gains tax accountant
Capital gains tax has a trap most sellers meet too late: UK residential property gains must be reported and paid within 60 days of completion — not in January, sixty days. Miss it and penalties run automatically. Selling shares, crypto or a business has friendlier deadlines but harder maths: allowable costs, matching rules, and reliefs that halve bills when claimed correctly.
How we handle it
We calculate the gain properly (including the improvement costs and purchase fees people forget to deduct), claim what applies — private residence relief, letting periods, business asset disposal relief at 10% — and file whichever return the asset demands, from £149 fixed.

Terms you'll meet along the way
60-day rule
UK residential property gains must be reported and the tax paid within 60 days of completion — separate from and earlier than Self Assessment.
Business Asset Disposal Relief
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.
Annual exempt amount
The slice of gains each person can realise tax-free per year — now small, which makes timing disposals across tax years worth planning.
UTR
Your Unique Taxpayer Reference — the 10-digit number HMRC issues when you register for Self Assessment. Lifelong, and needed for every return.
Payments on account
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.
SA100
The main Self Assessment return form. Supplementary pages bolt on for employment, self-employment, property, capital gains and foreign income.
Balancing payment
The difference between what your payments on account covered and what the year's tax actually was — settled each 31 January.
Capital gains tax accountant: your questions answered
I've just sold a rental property — what's the deadline?
Sixty days from completion to file the property CGT return and pay the tax — separate from and earlier than Self Assessment. If completion already happened, tell us the date today: late filing penalties start at £100 and grow, but the sooner it's in, the smaller the damage.
How is the gain actually calculated?
Sale proceeds minus purchase price minus buying and selling costs (legal fees, stamp duty, agent fees) minus capital improvements — extensions and renovations count, redecorating doesn't. Then the annual exempt amount, then the rate your income band sets. Documentation of old improvement costs is usually where we add the most value.
Does CGT apply to crypto?
Fully — every disposal including swapping one coin for another, not just cashing out to pounds. The share-matching rules apply, exchanges rarely give usable UK tax reports, and HMRC receives data from platforms. Our crypto tax service reconstructs the position from your transaction history.
What is the 60-day rule?
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.
What rate of CGT will I pay?
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.
Do I owe tax if I only swapped one crypto for another?
Usually yes — swapping token A for token B is a disposal for capital gains purposes, as is spending crypto. Only buying with pounds and holding is tax-free. This is the rule that surprises people most.
The CGT allowance is tiny now — does that affect me?
Almost certainly. The annual exempt amount is £3,000, so even modest gains are reportable and taxable. Losses matter more than ever too — registering them lets you offset future gains.
How does mortgage interest relief work now?
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.
Should I hold my properties in a limited company?
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.
What does the £129 fee include?
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.
I've missed the deadline — can you still help?
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.
