Capital Gains Tax Accountant

If you need a CGT accountant, Vexo Accounting provides capital gains tax advice and handles capital gains tax returns for clients right across the UK. We work out how much capital gains tax you owe, report the disposal to HMRC, and make sure you pay capital gains tax on time and not a penny more than necessary.

Getting this wrong is easy to do and expensive to fix. That is why so many people bring their tax return straight to us rather than trying to work out their capital gains tax alone, or paying tax they did not actually owe because a relief was missed.

We work with individuals, landlords, company directors, trustees and non-residents, and every capital gains tax case gets checked properly before anything is sent to HMRC.

Selling An Asset Can Trigger A Capital Gains Tax Bill You Did Not Plan For

Capital gains tax applies when you sell or dispose of an asset for more than you paid for it. That covers residential property, a buy-to-let, shares, a business, cryptocurrency, and in some cases personal possessions too.

HMRC figures show 378,000 people paid capital gains tax in the 2023/24 tax year, with total liabilities of £12.1 billion built on £65.9 billion of gains. Once you divide that out, the average capital gains tax bill worked out at around £32,000 per taxpayer, and that figure keeps climbing as the tax-free allowance keeps shrinking.

The annual exempt amount, sometimes called the CGT annual exemption or the annual exempt allowance, used to be £12,300 back in 2022/23. It dropped to £6,000, then dropped again, and now sits at just £3,000 for the 2026/27 tax year. Married couples and civil partners each get their own annual exempt amount, which gives £6,000 combined if both of you hold the asset.

That shrinking annual exempt amount means far more people now owe capital gains tax on gains that would have been tax-free only a few years back. HMRC's own figures show that around 40 percent of all CGT comes from taxpayers making gains of £5 million or more, even though this group makes up less than 1 percent of everyone who pays the tax. Roughly 48 percent of gains come from people with taxable income above £150,000, so higher earners feel this tax the hardest.

Missing a report, missing a deadline, missing a tax payment, or missing a relief you were entitled to can mean paying capital gains tax you did not need to pay, or facing a penalty from HMRC. That is where we come in with proper tax planning advice and capital gains tax reporting handled from start to finish.

Here Is Everything Our CGT Accountant Service Covers

We handle capital gains tax calculations, reporting and payment for individuals, landlords, business owners, UK residents, non uk residents and trustees. Below are the main areas clients bring to us for capital gains tax advice.

Selling A Residential Property Means A Strict 60 Day Deadline

If you sell UK residential property that is not your main residence, you generally need to report the gain and pay the tax within 60 days of the completion date. In 2024/25, 163,000 taxpayers reported a UK residential property disposal through HMRC's UK property account, covering 183,000 property disposals and £10.3 billion in gains.

We calculate your gain, apply any reliefs you are entitled to, and file the return through the UK property account before your deadline passes. If the property was your main residence for part of the time you owned it, we also check whether Private Residence Relief reduces or removes the bill, and we factor in any periods it was rented out.

We can also add qualifying improvement costs, such as an extension or a new kitchen, to your allowable costs where the paperwork supports it. This can lower your taxable gain on residential property by a decent amount on an older home, and it directly affects how much capital gains tax you pay on the sale.

Inherited A Property? We Establish The Right Value Before We Calculate Anything

When you inherit a property or other asset, your starting point for capital gains tax is usually its market value at the date of death, not what the original owner paid for it. Getting that probate value right matters, because it sets the base your future gain gets measured against, and it affects the proceeds figure we use when the property is eventually sold.

We work with the figures from probate, or help establish a market value where none was formally recorded, then calculate the gain correctly when you come to sell.

Selling A Business Or Company Shares Brings Business Asset Disposal Relief Into Play

If you are selling a business, a share in a personal company, or a partnership interest, Business Asset Disposal Relief can cut your capital gains tax rate to 18 percent on qualifying gains, up from 14 percent before April 2026. We check whether you meet the qualifying conditions, work out the relief available up to your lifetime limit, and build this into your exit planning well before the sale completes.

We also advise on gift holdover relief for certain gifts of business assets, and on the capital gains tax position when a company is restructured, incorporated, or reorganised. If you hold employee shares or shares through a company scheme, we work out how those disposals are taxed alongside everything else you own, including any income tax implications that run alongside the capital gains tax position.

Shares, Crypto And Investment Portfolios Need Careful Record Keeping

Share matching rules, pooled holdings and a patchy record of purchase dates make investment portfolios one of the trickiest areas of capital gains tax. We work through your full history, apply the correct matching rules, and make sure every disposal is reported the right way to HMRC.

Cryptocurrency is treated in a similar way to shares for capital gains tax purposes. We handle crypto to crypto exchanges, staking rewards, airdrops, and assets that have become lost or worthless, and we keep the records HMRC expects to see if they ever ask questions about a disposal.

If you hold EIS or VCT investments, we also look at how those reliefs interact with any gains or capital losses elsewhere in your portfolio, since the rules here can pull in different directions and can change the tax rates that end up applying.

Capital Losses And Tax Planning Advice Can Reduce What You Owe

Capital losses on one asset can be offset against gains on another in the same tax year, and unused losses can often be carried forward to future years. We track your capital losses properly and use them to bring your capital gains tax bill down wherever the rules allow it.

We also look at the timing of a disposal before it happens as part of our wider tax planning advice. Spreading sales across more than one tax year, or timing a sale around your other income, can change which tax rates apply and how much of the annual exempt amount you actually use.

Spouse And Civil Partner Transfers Can Change Your Tax Position

Assets transferring between spouses or civil partners are generally treated as though no gain or loss arose, which opens up planning opportunities before a sale. Transferring assets, or a share of one, to a lower-earning civil partner ahead of a disposal can sometimes reduce the tax due, depending on both of your circumstances and your basic rate band.

We look at whether this applies to your situation and handle the transfer and later disposal correctly, including any bank transfer records HMRC may want to see as proof of ownership changing hands.

Non-UK Residents Selling UK Land Have Their Own Reporting Rules

Non-residents disposing of UK land or property must report the sale using the non-resident capital gains tax process, usually within 60 days of completion, whether or not tax is actually due. Non-UK residents can face a penalty for failing to report correctly, even where no gain was made at all, and this is one of the most common places we see UK resident disposal rules confused with the separate rules for non-residents.

We handle this reporting for clients based overseas, work out any capital losses that need reporting too, and deal with the wider UK tax position that often runs alongside a property sale from abroad. If you are unsure whether the UK resident or non-resident rules apply to you, contact HMRC or speak to us first, since the reporting route depends on your residence status on the completion date.

Divorce Or Separation Often Brings Capital Gains Tax Questions Too

Transfers of property or investments as part of a divorce or separation settlement can trigger capital gains tax, and the rules around this changed in recent years to give separating couples more time. We work through what is being transferred, when, and to whom, then calculate any tax due as part of the wider settlement.

Trustees And Personal Representatives Get Support With Estate Disposals Too

Selling assets out of a trust or an estate brings its own capital gains tax rules, including a lower annual exempt amount than an individual gets. We calculate gains for trustees and personal representatives, work out what the trust or estate owes, and file the correct report and pay submission on time.

In limited circumstances, such as gifts of land or certain unquoted shares, HMRC allows the tax to be paid in annual instalments rather than as one lump sum, and special rules decide how those annual instalments are worked out. We check whether this applies to your situation and set the payments up correctly if it does.

We handle tax liabilities that span more than one of your property disposals just as carefully for non-residents as we do for UK residents based here. Once the figures are agreed, we report the disposal to HMRC and confirm the CGT position with you in writing, and if a further sale follows later in the year, we report the disposal again rather than assuming the first filing covers it. Every client receives a copy of their report for their own records.

Missing Records Do Not Stop Us Working Out Your Gain

Some clients come to us with only part of the paperwork for an asset they bought years ago, especially where it has passed through family members or changed hands more than once. We piece together acquisition costs from bank statements, old contracts, solicitor letters and HMRC's own records where possible, so your gain is not overstated simply because a receipt went missing.

Where an asset has become worthless or practically impossible to sell, such as shares in a company that has folded, we also look at whether a negligible value claim applies. This can let you bank the loss now rather than waiting until you formally dispose of the asset, and it can reduce a future capital gains tax bill on other gains too.

Complex Or Staged Disposals Still Get Calculated Properly

Not every disposal is a single clean sale. Assets acquired in stages, part disposals, transfers into a company, or an asset that changed hands within the family before the final sale all need their own calculation, and other disposals in the same tax year can affect the total tax due. We break each stage down and work out the gain correctly rather than treating it as one simple transaction.

Planning To Sell? We Can Look At The Tax Position Before You Commit

A lot of the benefit in getting tax planning advice from a CGT accountant comes before a sale, not after it. If you are thinking about selling a property, a business, or a large shareholding, we can review the likely tax position first, so you know roughly how much capital gains tax you will owe and whether any planning steps could reduce it.

This might include using this year's annual exempt amount and next year's annual exempt amount across two disposals, checking whether Business Asset Disposal Relief conditions are met before you agree a sale, or reviewing whether transferring assets to a spouse makes sense given your combined income. We can also factor capital gains tax into wider estate planning alongside inheritance tax, particularly where gifting assets during your lifetime is being considered.

Gifting Assets Or Personal Possessions Can Still Bring Capital Gains Tax Into Play

Giving an asset away to family members is usually treated as a disposal at market value for capital gains tax purposes, even though no money changes hands and no proceeds are actually received. We work out whether a gift triggers a gain, and whether any relief, such as gift holdover relief on business assets, softens the bill.

Personal possessions sold for £6,000 or less are often exempt from capital gains tax, which covers a lot of everyday sales, but higher value personal possessions like art, jewellery or a classic car can still bring a gain into charge. We check whether an item you have sold or gifted falls inside or outside that exemption before assuming either way, since the exemptions here have their own special rules.

How We Work Out Your Gain Proceeds, Market Value And Allowable Costs

How We Work Out Your Gain: Proceeds, Market Value And Allowable Costs

Capital gains tax is charged on the profit you make, not on the full proceeds of a sale. We start with the sale price, or the market value where an asset was gifted rather than sold, then deduct what you originally paid, plus certain costs of buying, improving and selling the asset.

Ownership records matter here. If you bought an asset jointly, inherited a share of it, or added to your holding over several years, we work out the correct cost figure for the specific share you have sold. Getting the ownership history right is often what separates an accurate capital gains tax figure from one that overstates your profit and costs you money unnecessarily.

Your income also plays a part in the calculation, because your capital gains tax rate depends on how much of your basic rate band is left once your income tax position is taken into account. We ask about your income for the tax year in question so the correct tax rates get applied to your gain, rather than assuming the higher rate applies by default. Interest earned on savings does not usually affect this, but other income sources can, so we always check the full picture before finalising a capital gains tax return.

Get Your Capital Gains Tax Right Before You Sell

Let Vexo Accounting calculate your gain, check the reliefs and allowable costs available to you, and report the disposal to HMRC correctly and on time.

How Capital Gains Tax Reporting And Payment Works With Us

Getting started is simple and does not take long.

  • Send us the details of what you have sold or plan to sell, including purchase and sale dates, costs, proceeds, and any paperwork you already have.
  • We calculate your gain, apply the reliefs and exemptions that apply to you, and confirm the capital gains tax due before anything is filed.
  • We report the disposal to HMRC, whether through the UK property account, your self assessment tax return, or the non-resident reporting service, and confirm your tax payment has gone through.

Most residential property sales are reported and paid through the UK property service within 60 days of completion, using HMRC's online services rather than a paper form. Other capital gains, such as shares or a business sale, are usually reported through your annual self assessment tax return instead, with the tax payment due by the following 31 January.

We can also set you up with a government gateway login and personal tax account if you do not already have one, since both the UK property account and self assessment run through these HMRC online services directly. Where a paper form is genuinely the right route rather than HMRC's online services, we handle that too, though most clients find the personal tax account faster once it is set up.

We keep in touch with HMRC on your behalf throughout the process. If a query lands after your capital gains tax return has gone in, or if we need to contact HMRC directly to resolve something, we deal with it rather than passing it back to you.

Every capital gains tax case ends with some form of report to HMRC, and we prepare that report whether it covers one UK residential property disposal or several in the same tax year. A residential property sale gets its own report through the UK property account, a share sale usually sits inside your annual self assessment report, and a sale by a non uk resident needs its own separate report regardless of whether tax is due. We check each report before it goes anywhere near HMRC, then keep a copy of every report on file in case you need it again, and we make sure every UK resident and non-UK resident client understands what has been reported on their behalf.

Most clients pay their capital gains tax in a single payment once the report has been filed, though annual instalments remain an option in the limited circumstances we mentioned earlier. We confirm each payment has reached HMRC and match it against the CGT reference so nothing gets lost between systems. If you have already sold an asset this year, or sold more than one, get in touch, and we will start working through the numbers straight away, whatever has been sold and whenever it was sold.

We report on time, we help clients pay capital gains tax on time, and we track every payment until HMRC confirms it. If you need CGT advice before you decide how or when to pay, or you simply want us to pay capital gains tax on your behalf once the figures are agreed, we are ready to help. Some clients would rather pay tax as soon as the figures are confirmed, while others prefer to pay closer to the deadline once they have set money aside, and either way we make sure the report and the payment both land on time.

How Much Does A Capital Gains Tax Accountant Cost in the UK

How Much Does A Capital Gains Tax Accountant Cost in the UK?

Fees for capital gains tax work across the UK typically start around £300 to £500 for a single residential property or share disposal, and rise toward £1,000 to £2,000 or more where several assets, a business sale, or non-resident reporting are involved. A standalone capital gains tax return, separate from a full self assessment, often falls somewhere between £400 and £600 depending on how much work is involved.

Based on recent projects we have completed for clients, most straightforward property or share disposals land within that same range once we have reviewed the full picture and confirmed the proceeds and allowable costs. More involved cases, such as a business sale with Business Asset Disposal Relief or a portfolio with dozens of disposals, understandably cost more because of the extra time needed to get every figure right before you pay.

A few things push the price up or down. The number of separate disposals in one tax year matters, as does whether records are complete or need to be pieced together from old paperwork. Whether the return needs filing under the tight 60-day property deadline, rather than the more relaxed self assessment timeline, can also affect the fee, since urgent tax return work takes priority in our schedule.

This is a rough guide only, and the actual cost varies depending on how many disposals you have, how complete your records are, and how close you are to a reporting deadline. Contact us for a free quote, and we will give you a fixed price before any work begins, so there are no surprises later.

Why Property Sellers And Business Owners Across The UK Choose Vexo Accounting

We deal with capital gains tax cases every week, from a single buy-to-let sale through to a full business exit with Business Asset Disposal Relief involved. That means we know the reliefs, deadlines and reporting routes properly, and we apply them correctly the first time, whether the report and pay route is HMRC's UK property service or a full self assessment tax return.

As an experienced accountancy firm, we manage the filing directly with HMRC on your behalf, including any correspondence if a question comes back later. You get a fixed quote before we start, a clear list of what we need from you, and a straight answer on your capital gains tax position rather than vague guesswork.

A few things clients say matter most:

  • A fixed price agreed before we start, with no surprise bills afterward.
  • Deadlines tracked for you, so the 60-day property rule or your self assessment date never gets missed.
  • Direct contact with the person handling your capital gains tax case, not a call centre.

Whether you are a UK resident selling a family home that was rented out for part of the time you owned it, a landlord selling a portfolio of residential property, or a non-resident dealing with a UK land or property sale from abroad, we have handled cases like yours before, including the specific pages of HMRC guidance that apply to less common situations.

We stay up to date with changes to capital gains tax rates, allowances and reliefs each year, including the move to 18 percent and 24 percent CGT rates and the phased rise in Business Asset Disposal Relief, so your return always reflects the rules that actually apply on your disposal date rather than out-of-date figures. That matters more than ever now that the annual exempt amount is so low and more ordinary disposals fall within the tax.

The government has also tightened reporting expectations in recent years, so we make sure every capital gains tax return we file meets current HMRC standards, with the right supporting evidence kept on file in case of a future check.

FAQS

Frequently Asked Questions

Clear answers to the most common questions about our accounting services.

What does a capital gains tax accountant do?

A capital gains tax accountant calculates your gain, checks the available reliefs and exemptions, reports the disposal to HMRC and helps make sure the tax is paid by the correct deadline. They can also advise on tax planning before you sell a property, business, shares or another asset.

How much does a capital gains tax accountant cost in the UK?

A capital gains tax accountant typically charges around £300 to £500 for a straightforward residential property or share disposal, with more complex cases often costing £1,000 to £2,000 or more. A standalone capital gains tax return is often around £400 to £600, depending on the work involved.

How long do I have to report capital gains tax on a property sale?

You generally have 60 days from completion to report and pay capital gains tax on a UK residential property that is not your main residence. A capital gains tax accountant can calculate the gain, check applicable reliefs and file the report through HMRC's UK property account before the deadline.

How is capital gains tax calculated on the sale of a property?

Capital gains tax on a property sale is calculated from the gain rather than the full sale proceeds, starting with the sale price and deducting the original purchase cost and qualifying costs of buying, improving and selling the property. Reliefs such as Private Residence Relief may also reduce the taxable gain where the property was your main residence for part of the ownership period.

Can capital losses reduce my capital gains tax bill?

Capital losses can reduce your capital gains tax bill because losses on one asset can generally be offset against gains on another in the same tax year, with unused losses often carried forward. A capital gains tax accountant can track the losses and apply them where the rules allow.

Can a capital gains tax accountant help before I sell an asset?

A capital gains tax accountant can review the likely tax position before you sell a property, business or large shareholding and identify planning opportunities that may reduce the eventual bill. This can include checking reliefs, using annual exempt amounts across tax years, reviewing spouse transfers and considering the timing of the disposal.
