How buying works
Calculate first, pay once, download straight away
1
Calculate for free
Choose your tax years, add your exchange files and review the results. Nothing leaves your browser except coin symbols and dates when a price is missing.
2
Pay once with Stripe
Card payment in pounds through Stripe Checkout. Launch discount codes can be entered at checkout. We never see your card number.
3
Download your PDF
Your browser sends only the computed figures to our server, which renders the PDF, streams it back and deletes the figures immediately. Re-download for 7 days.
Before you pay
Two confirmations the law requires
A report is digital content supplied straight away. Under the Consumer Contracts Regulations 2013 you would normally have 14 days to cancel, so before payment we ask you to confirm that you want the report supplied immediately and that you understand the cancellation right is lost once it has been generated. Losing that right does not remove your rights to a report of satisfactory quality: if a report fails to generate or is materially defective and we cannot fix it, you get a full refund. See the refund policy in our terms.
Questions
Pricing questions
Do I have to pay to see my results?
No. Import, review and per-year totals — disposals, proceeds, gains and losses, estimated tax, crypto income and whether you need to report — are free with no account. You only pay if you want the PDF report with the full working.
What is the difference between the two reports?
The Tax Year Report (£29) covers one tax year: summary, SA108 boxes, every disposal with its same-day / 30-day / pool breakdown, pool statements, income, transfers, flagged items, valuation sources and import log. The HMRC Letter Pack (£59) contains the same sections for up to six tax years in one PDF, plus a disclosure worksheet for each unreported year, a letter-response checklist and CSV exports for an accountant.
Can I buy the report after I have seen my free results?
Yes — that is the normal order. Calculate first, check the results, then choose the report. The figures in the PDF are exactly the figures you saw, because your browser sends the computed report data (not your files) to our server to be rendered.
Which tax years can I buy?
Any tax year from 2019/20 to 2026/27. A Tax Year Report covers one year; the HMRC Letter Pack covers up to six years, which is enough for the years a typical HMRC letter asks about, including the 2024/25 mid-year rate change.
Is this a subscription?
No. Each purchase is a one-off payment through Stripe Checkout. There is no account, no renewal and nothing to cancel. If you need another year later, you buy another report then.
What if my report fails to generate?
You get a full refund. Reports that fail to generate, that are corrupted or incomplete, or that do not reflect the figures shown to you before purchase are refunded in full if we cannot fix them. Email us with your report ID within 14 days; refunds go back to the original card through Stripe.
Do you keep my report or my transaction files?
Your files never leave your browser. When you buy a report your browser sends the computed figures to our server, which renders the PDF, streams it back to you and deletes the figures straight away. If you tick “email me a copy”, an encrypted copy of the figures is kept for 7 days so the link works, then deleted. Stripe keeps the payment record.
Do you offer discount codes?
Launch and early-bird codes can be entered on the Stripe payment page when we run them. We never publish codes we do not actually honour.
Is the report tax advice? Will HMRC accept it?
It is a calculation, not advice, and it is not approved or endorsed by HMRC — no software is. It applies HMRC’s published rules (same-day, 30-day and section 104 pooling) to your data, shows every step and cites the source of every rate, so you or your accountant can check it and attach it to your return as your computation. You remain responsible for what you file.
