Frequently Asked Questions

Who needs to file a CGT return when they sell a UK home?
Anyone who sells UK residential property at a gain and does not get 100 % Private Residence Relief must file a CGT return, even if the tax due is £0. Exemptions normally apply only when the property has been your sole/main home for the entire ownership period.
How much does swiftcgt cost?
One flat fee: £299. That covers expert review, CGT calculation and HMRC electronic submission—no hidden extras.
How fast will my return be filed?
Upload your details and documents online; a UK-chartered accountant reviews them and files within 3 working days once we have received your approval.
What information or documents do I need to provide?
Sale and purchase contracts (or completion statements), dates, purchase and selling prices, allowable improvement costs, letting periods, and any valuations. Swiftcgt’s onboarding form flags the exact items and lets you drag-and-drop PDFs or photos.
Can I use your service if the property was owned jointly?
Yes. Each owner needs their own CGT return, but we prepare linked filings and apply reliefs correctly. A joint-owner add-on costs £199 per extra owner.
Do I still need to complete Self Assessment?
Only if you have other gains or income that put you in Self Assessment. A standalone CGT return via swiftcgt satisfies the property requirement.
Do I pay CGT on my main residence?
Usually not. Private Residence Relief eliminates CGT if the property has been your only or main home for the whole ownership period and certain conditions are met. Partial relief may still reduce the gain if you lived there only part-time.
No stress. No surprises.
Just £299.
We’ll handle your CGT return from start to finish — and if you’re not satisfied, you get your money back.
