Sound familiar?
Not entirely sure what you owe — or when.
Capital gains tax is one of the areas where people most commonly either overpay or file late without realising the deadlines apply to them. The rules differ depending on what you sold, when you sold it, and whether you qualify for any reliefs. Getting the calculation wrong can mean a penalty, an unexpected bill, or leaving money on the table by missing allowances you were entitled to.
- Unsure whether the disposal needs reporting now or via self assessment
- No idea whether Business Asset Disposal Relief or other exemptions apply to you
- Calculated a rough gain but not confident the figure is right or defensible
What a correctly handled CGT return looks like
The right approach is methodical: establish the disposal proceeds, deduct allowable costs, check eligibility for every relevant relief, and file within the correct window. That is what we do, and we walk you through the numbers in plain English before anything is submitted.
- We confirm exactly how and when your disposal needs to be reported to HMRC
- Every available relief — Business Asset Disposal, Private Residence, Annual Exempt Amount — reviewed and applied where eligible
- Your gain calculated correctly, with a clear breakdown you can follow and keep on record
- Tailored quote upfront — you know the cost before we begin, with no fixed-fee guesswork on complex CGT work

What the CGT service covers
A complete capital gains tax return — from establishing your gain to filing with HMRC — handled by a qualified accountant who explains every step in plain terms.
Accurate CGT Calculation
We work through your disposal proceeds, acquisition costs, improvement expenditure, and any incidental costs to arrive at the correct chargeable gain. Every deduction you are entitled to is identified — none are missed because we did not ask the right questions.
Included as standardReliefs and Exemptions Review
Business Asset Disposal Relief, Private Residence Relief, lettings relief, the Annual Exempt Amount — each is assessed against your specific circumstances. If a relief applies, we apply it. If it does not, we tell you why, so there are no false expectations.
Checked for every clientFiling Within the Right Window
UK residential property disposals must be reported and any tax paid within 60 days of completion — separate from your self assessment. Other disposals are reported via self assessment. We handle whichever applies, on time, with confirmation once filed.

What sets us apart on CGT work
CGT is one of those areas where the difference between a careful accountant and a careless one shows up directly in what you pay HMRC. Here is what you get with us.
No gain left miscalculated
CGT calculations involve more moving parts than most people expect — base cost, improvement costs, indexation on older assets, part-disposal rules. We go through your disposal in full rather than working from a rough figure you supply. The number we submit is one we can defend if HMRC asks.
The 60-day deadline managed for you
If you sold a UK residential property, the 60-day reporting and payment window starts from completion — not from when you got around to thinking about it. We flag the deadline as soon as you come to us and work to it, not around it. Late filing penalties start at £100 and increase; there is no reason to risk them.
Plain-English numbers, not jargon
Before we file anything, we show you the gain, the reliefs applied, the tax due, and when it is payable — in plain terms. You will not be left wondering what was submitted on your behalf or why your bill is what it is. Understanding your own tax position is part of what you are paying for.
Your CGT return sorted in four steps
Most clients are up and running within a few days of getting in touch. The process is straightforward and we handle the majority of it.
Tell us about the disposal
Use the quote form to give us the basics — what was sold, when, and for how much. No need to have everything to hand at this stage; we will ask what we need. You will receive a tailored quote, usually the same day.
We gather the details
Once instructed, we collect the information needed to calculate your gain accurately: acquisition costs, improvement expenditure, sale proceeds, and any relevant relief history. We ask targeted questions rather than sending a generic checklist.
We calculate and explain
We produce a clear CGT computation — gain, reliefs, annual exempt amount, tax due — and walk you through it before filing. You approve the figures and we answer any questions in plain English. Nothing is submitted until you are comfortable with what it says.
Filed, confirmed, done
We submit to HMRC and send you confirmation. You know exactly what was reported, what you owe, and when to pay it. The return is on record, the deadline is met, and there is considerably less to think about.
“Prads and the team made filing our accounts so easy. They were patient, knowledgeable, responsive and good to work with. We would highly recommend them. Thanks Prads!”
Common questions about CGT returns
Do I need to report a capital gain separately from my self assessment return?
It depends on what you sold. If you disposed of a UK residential property, you must report the gain and pay any tax due within 60 days of completion using HMRC’s online service — regardless of whether you file a self assessment return. Gains on other assets such as shares, commercial property, or business assets are reported through your annual self assessment. We confirm which route applies to your disposal and handle the filing accordingly.
How much does a capital gains tax return service cost?
CGT work is quoted individually because the complexity varies significantly — a straightforward residential property disposal differs considerably from a part-disposal with improvement costs and a Business Asset Disposal Relief claim. We provide a tailored quote before any work begins, so you know the cost upfront. Use the form on this page and we will come back to you, usually the same day.
I have already missed the 60-day deadline — can you still help?
Yes. A late report does not prevent us from filing — it means a penalty has likely already accrued, but we can submit the return, calculate the tax due, and ensure nothing further is outstanding. Addressing it promptly limits the interest and penalty exposure. We will be straightforward with you about what has accrued and what the next steps are.
Is there a contract or minimum commitment?
CGT return work is a one-off engagement — there is no ongoing contract, no retainer, and no lock-in. You instruct us for the disposal in question, we complete the work, and that is the end of it unless you choose to come back for something else. Many clients do, but there is no obligation.
Can you help with Business Asset Disposal Relief on the sale of a company or business?
Yes. Business Asset Disposal Relief (formerly Entrepreneurs’ Relief) reduces the CGT rate to 10% on qualifying gains up to the lifetime limit, subject to conditions around shareholding, officer status, and the holding period. We check whether your disposal qualifies, apply the relief in the computation where it does, and explain the outcome clearly. If the conditions are borderline we will tell you that too, rather than applying it and hoping for the best.
Can I offset losses from previous years against this gain?
Yes, provided those losses were reported to HMRC in the relevant tax year — either through a previous self assessment return or a standalone CGT report. Unregistered losses cannot generally be claimed retrospectively beyond a four-year window. We check your position, identify any losses available for offset, and apply them in the computation to reduce the chargeable gain where possible.
