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.

Here's what we typically need to calculate and file your CGT return:

• Your completion statement from your solicitor (this shows the sale price and any deductions at completion)
• Your original purchase completion statement showing what you paid and any associated costs at the time
• Receipts or records of any capital improvements made to the property during your ownership (extensions, loft conversions, new kitchens — general maintenance doesn't count)
• Details of how the property was used over your ownership period (main home, rented out, vacant, shared use)
• If it was let at any point, approximate dates and rental income figures

You don't need to have everything perfectly organised before getting in touch. Fill in our CGT form with what you have and we'll tell you exactly what else we need.

They're separate obligations, and both may be required.

The 60-day CGT return is a standalone filing that must be done within 60 days of completion — it's not part of your annual Self Assessment return.

If you already file Self Assessment, you'll also need to declare the gain on your annual return for the tax year the sale took place in, even though you've already reported it via the 60-day return. The tax itself is paid via the 60-day return; the Self Assessment entry reconciles it for the full year.

It sounds like double admin, but we handle both as part of our service. If you need a CGT return plus a Self Assessment return for the same year, message us on live chat and we'll work out the best way to handle everything together.

Yes, you can still file — and you should do so as soon as possible.

HMRC will charge a late filing penalty automatically once the 60-day window has passed, and interest accrues on any unpaid tax. But the longer you wait, the more these charges build up.

Filing late is always better than not filing at all. HMRC may also consider the circumstances of the delay when deciding whether to pursue further action.

Message us on live chat right away and we'll file as quickly as possible to stop anything else building up.

The 60-day clock starts from the completion date, not the exchange of contracts.

Completion is the day the sale legally finalises — when the money changes hands and the keys are handed over. Exchange can happen weeks before this, but it doesn't start the clock.

It's 60 calendar days from completion, including weekends and bank holidays. For example, if your property completed on 1 July, your deadline would be 29 August.

Don't leave it close to the deadline — we need time to gather the information and file on your behalf. Message us on live chat as soon as completion happens.
