Frequently Asked Questions

Yes, and we'd encourage it. You can file any time after 5 April when the tax year ends.

Filing early doesn't mean paying early — any tax you owe is still due on 31 January regardless of when you file. But filing early means you know your bill months in advance, can budget for it, avoid the January rush, and skip the risk of missing the deadline.

If you're due a refund, filing early also means you get it sooner.

We're available to file your return from April onwards — no need to wait until autumn.

For the 2025/26 tax year (6 April 2025 to 5 April 2026):

• Register for Self Assessment (if first time): 5 October 2026
• File a paper return: 31 October 2026
• File online and pay any tax owed: 31 January 2027
• Second payment on account for 2024/25: 31 July 2026

Missing any of these deadlines can result in penalties and interest, so it's worth getting your return filed well in advance.

We can file as soon as the tax year ends on 5 April, so there's no need to leave it to January.

One amendment is included at no extra cost within 12 months of the original filing date.

If something changes after we've filed — a P60 arrives with different figures, you realise you forgot to include some income, or HMRC queries something — just let us know via live chat and we'll sort it out.

HMRC allows amendments to be made up to 12 months after the filing deadline for that tax year.

Yes. Before we file, we check for any reliefs and allowances you're entitled to — including the personal allowance, trading allowance, property allowance, pension contributions, Gift Aid, Marriage Allowance, and any allowable business expenses.

We won't file until we're confident your return is accurate and as tax-efficient as possible.

If we spot something that could reduce your bill, we'll flag it.

Several costs can be deducted from your gain, reducing the amount of CGT you pay. They fall into three categories.

Selling costs: estate agent fees, solicitor fees, and any costs directly related to the sale.

Buying costs: the original purchase price, solicitor and surveyor fees, and Stamp Duty Land Tax paid at purchase.

Improvement costs: the cost of capital improvements made to the property during your ownership — things like extensions, loft conversions, new kitchens or bathrooms that added value.

What you can't deduct: general maintenance and repairs (fixing a boiler, repainting, replacing like-for-like fittings), mortgage interest, or insurance costs.

The formula is: sale proceeds, minus allowable selling costs, minus original purchase price and buying costs, minus capital improvements.

Each of these deductions is applied as part of our CGT filing service — you don't need to calculate anything yourself. Just share the relevant receipts and documents and we'll handle the rest.

Yes. Estate agent fees are one of the allowable costs you can deduct when calculating your capital gain, which directly reduces the amount of tax you owe.

Here's what you can deduct from the sale price:

• Estate agent or auctioneer fees
• Solicitor or conveyancer fees on the sale
• Any advertising costs related to the sale

You can also deduct costs from the original purchase:

• The price you paid for the property
• Solicitor and surveyor fees at the time of purchase
• Stamp Duty Land Tax paid when you bought it
• The cost of any capital improvements made during your ownership, such as an extension or loft conversion

General maintenance and repairs don't count as improvements and can't be deducted.

Getting these deductions right can make a significant difference to your bill. If you're unsure what qualifies, message us on live chat.

Yes. Non-UK residents are required to report the sale of UK residential property to HMRC within 60 days of completion, regardless of whether any tax is owed.

This applies even if you made a loss or the gain is fully covered by Private Residence Relief. The reporting obligation still stands.

Non-residents may also be subject to Non-Resident Capital Gains Tax (NRCGT), which has applied to UK residential property sales since April 2015. The tax calculation for non-residents can be more complex, particularly around the rebasing rules that apply to property owned before April 2015.

We handle non-resident CGT returns regularly. Message us on live chat and we'll confirm what applies to your situation, or book a call with us if you'd prefer to talk it through.

Our CGT filing options are priced based on the number of owners on the property title.

Solo (£299): for a single owner. Covers the full gain calculation, all applicable reliefs, and filing with HMRC within the 60-day window.

Joint (£449): for two owners selling together — typically a couple, but also applies to friends or investors who co-own a property. We calculate and file for both owners in one service.

Trio (£598): for three owners on the same title — common with inherited properties where siblings jointly own the estate. Covers all three owners in one filing.

All options include the full gain calculation, relief checks (including Private Residence Relief and Lettings Relief where applicable), and submission to HMRC.

Not sure which applies to you? Check the property title or message us on live chat.
