What did you sell?

Pick your asset and see what applies

Whether you have sold a second home, shares, a business or a buy-to-let property, the rules that apply to your Capital Gains Tax Return can differ significantly. Select the asset you have disposed of and our South Wales team will walk you through the reliefs, allowances and reporting requirements that matter to you. It is a clear, practical way to understand your position before you file.

Selling a second home or buy-to-let

Gains on residential property that is not your main home are taxed at 18% or 24%. If the sale completed, you usually have 60 days to report it and pay the tax, so speed matters.

Key facts

Selling shares, funds or investments

Shares and funds held outside an ISA or pension can trigger a gain when sold. We apply the same-day, 30-day and Section 104 pooling rules so your cost base is right.

Key facts

Selling, swapping or spending crypto

Every disposal of crypto, including swaps between coins and spending, can create a gain. We rebuild your transaction history across exchanges and wallets into a record HMRC accepts.

Key facts

Selling a business or company shares

Selling your business or your shares in a company can be your biggest tax event. We check whether Business Asset Disposal Relief applies and plan the figures before you file.

Key facts
How it works

From sale to filed, without the stress

We take the paperwork off your hands, from gathering disposal details and calculating your gain to preparing and submitting your Capital Gains Tax Return on time. Our South Wales accountants keep you updated at every stage so there are no surprises and no last-minute panic. You get a clear, organised process that turns a daunting task into a straightforward one.
1

Tell us what you sold

Complete the short quote form or book a call. Share the asset, the sale date and roughly what you paid.

2

We calculate your gain

An accountant works out the gain, applies costs, allowances and reliefs, and tells you exactly what you owe.

3

We file and confirm

We submit your return or 60-day report to HMRC, send you the confirmation and explain how to pay.

What you'll need to hand

Missing something? Don’t worry. We’ll help you track it down.

Worked example

See how a gain becomes a tax bill

A capital gain is not the same as the tax you owe, and understanding the journey between the two makes your bill far less intimidating. We explain how proceeds, allowable costs, reliefs and your annual allowance interact, then show you the resulting figure in plain English. Our South Wales accountants make sure you know exactly how your Capital Gains Tax Return has been worked out.

Reliefs & allowances

Legitimate ways to reduce your bill

There are plenty of lawful reliefs and allowances that can bring your capital gains liability down, but they are easy to miss if you are filing alone. Our South Wales accountants review your circumstances and apply every relevant relief, from private residence relief to business asset disposal relief, so you never pay more than you need to. Everything we do stays firmly within HMRC rules.
01

Annual exempt amount

The first slice of your gains each tax year is tax-free. We make sure it is used.

02

Private Residence Relief

If the property was ever your main home, part or all of the gain may be exempt.

03

Business Asset Disposal Relief

Selling all or part of a qualifying business can attract a lower rate of tax.

04

Spouse transfers

Assets passed between spouses or civil partners usually create no gain or loss, which opens planning options.

05

Loss relief

Losses on other disposals can be set against gains now or carried forward for later years.

06

Allowable costs

Legal fees, stamp duty, agent fees and improvement costs all reduce your taxable gain.

I worked with Accotx on a HMRC reclaim and overall, they did ultimately deliver on their promise, which I appreciate. The process did take longer than any of us expected, partly due to external delays with the tax authorities, and partly because there were some hiccups in communication and follow-up. However, despite those challenges, they stayed professional and stuck to the original agreed terms. If you’re considering using them, be prepared to stay in regular contact to keep things moving along. They are absolutely capable, have the expertise and willing to work with you, and overall improving their services over time. I would certainly return for any future needs.

I highly recommend Imran to anyone looking for a reliable and knowledgeable accountant. He helped me sort out a very complicated backlog of accounts and prepared my overdue tax returns with professionalism and attention to detail. Throughout the process, he was incredibly patient, took the time to answer all of my questions, and explained everything clearly. He guided me through each step and helped rectify issues that had built up over time, making what felt like an overwhelming situation much more manageable. I'm very pleased with the service I've received and truly appreciate his support. If you need help with your accounts or taxes, I would highly recommend Imran.

We worked with a few different accountants before finally settling with Accotax, and we’re really glad we did. Their team is great. Abdul is responsive and easy to reach whenever I have a question, which makes a big difference. They take the time to understand how our business works and what our needs are. They are very knowledgeable, and when they don’t have the answer straight away, they take the time to look into it and get back to us quickly. Anum, who looks after our account on a day-to-day basis, including reconciling invoices and preparing the annual accounts, is amazing. She is professional, efficient, and follows the processes we have put in place together. She's also very quickin getting back to us whenever needed. We’re very happy to work with her and hope to continue doing so for as long as possible. Overall, Accotax has made our accounting experience much smoother and easier. We see them as a long-term partner as our business continues to grow. I would 100% recommend them.
Why choose us

Doing it yourself versus letting us handle it

Filing a Capital Gains Tax Return yourself is possible, but the calculations, deadlines and reliefs can quickly become overwhelming, especially when a mistake means penalties or overpaying. Handing it to our South Wales accountants gives you accuracy, peace of mind and more of your time back. We handle the detail so you can focus on what matters to you.

On your own

With Cheap Tax Returns

Common mistakes

What catches people out most often

Missed reporting deadlines, forgotten allowable costs and misunderstood reliefs are among the most common pitfalls we see on Capital Gains Tax Returns. Property disposals also carry their own 60-day reporting requirement that many people simply do not know about. Our South Wales accountants spot these issues early and make sure your return is complete, accurate and filed on time.

Missing the 60-day deadline

The clock starts at completion, not when you receive the money. Late reports can lead to penalties and interest.

Ignoring crypto-to-crypto swaps

Swapping one coin for another counts as a disposal, even if you never moved money into a bank account.

Forgetting allowable costs

Fees, stamp duty and improvement costs are often left out, which inflates your gain and your tax bill.

Not reporting losses

Losses must be reported to HMRC to be used later. Unreported losses can’t be carried forward.
