How it works

Four steps, a fixed price agreed before any work starts, and a pack that shows every calculation.

Most packs take 5 to 10 working days from complete data. For 31 January returns, we need everything by 8 January.

What's in your pack

  • SA108 capital gains figures, ready to enter or hand to your accountant
  • Every disposal listed, with same-day, 30-day and section 104 matching shown
  • Staking and airdrop income and futures results set out separately
  • A plain list of every estimate and assumption made
  • Losses you can claim, with the deadline for each
  1. Free checkA 2-minute form or a short call. We look at what you hold and where, and agree one fixed price for the tax year before any work starts. Paying in full starts the work.
  2. Send your filesWe send a checklist of exactly which exports and wallet addresses we need. You upload them through an encrypted link, never plain email. Prefer to keep them on your own computer? Book a Private Session, by screen-share or in person.
  3. ReconciliationWe match transfers, trace gaps on-chain and apply UK rules, then send you a draft with any questions and assumptions flagged.
  4. Your reportOnce you're happy, you get the final pack. File it yourself, use your own accountant, or let a partner accountant review and file it for you. Our working files are then deleted.

Private by design

We only ever need exchange exports and public wallet addresses.

We will never ask for passwords, API keys or seed phrases.

  • Files arrive by encrypted transfer and are handled on an encrypted machine
  • Your files are never kept in cloud storage or shared with third parties; the transfer service only holds them, encrypted, until we download them
  • Working files are deleted on completion; we keep only your final report and the records the law requires

Private Session: your files never leave your computer

For sensitive portfolios, we work on your own computer over an end-to-end encrypted screen-share that is never recorded. Your files never leave your computer. Sessions are booked in two-hour blocks after a short setup call.

Prefer to meet in person? Available on request, quoted per case.

Questions

Do you file my return or give tax advice?

No. GainPal prepares the figures but does not give tax advice or file returns. You can file it yourself or use your own accountant, or one of our partner accountants can review your pack, advise and file it for you.

Can the price be adjusted for my situation?

Yes. If your case doesn't fit a tier neatly, tell us on the free check and we'll agree a fixed price before any work starts.

I already use Koinly or similar. Do I need you?

Maybe not. A £99 Report Review tells you whether your report has problems worth fixing, and the fee is deducted if you then want the full pack.

How and when do I pay?

Pay in full through a secure payment link when you accept your fixed price. If anything in your pack is wrong because of our work, we'll correct it free, and if we can't complete it, you're refunded for the work not done.

What do you need from me?

Exports from your exchanges and the public addresses of your wallets. We send a checklist.

I haven't reported earlier years. Can you help?

Yes. We prepare packs for earlier years; any disclosure to HMRC is made by you, your accountant or one of our partner accountants.

What if HMRC questions the figures?

Your pack shows every calculation, match and assumption, so the figures can be followed line by line.
