Help & Support
How can we help?
Common questions answered below. If you cannot find what you need, email us at hello@polyconomic.com.
Getting started
How do I import my transactions?
You can connect your exchange via API for automatic sync, or export a CSV from your exchange and upload it. We support 400+ exchanges. Go to the Imports section in your dashboard and choose your exchange from the list.
Which exchanges do you support?
We support 400+ exchanges and wallets including Binance, Coinbase, Kraken, Bybit, OKX, eToro, Revolut, and many others. See the full list on our integrations page.
My exchange is not on the list. What do I do?
Most exchanges allow you to export a CSV of your transaction history. Upload that and we will detect the format automatically. If you cannot get it to work, email us and we will help.
Do I need to enter every transaction manually?
No. If your exchange is supported, you connect it and we import everything. Manual entry is available as a fallback for transactions that cannot be imported any other way.
Calculations
How does Polyconomic calculate my gain?
We apply HMRC's required matching rules in the correct order: same-day first, then the 30-day rule, then the section 104 share pool. This is the legally required method for UK crypto tax calculations.
What if I have made a loss?
Losses are calculated the same way as gains and are shown separately. You can use losses to offset gains in the same tax year, or carry them forward to future years by claiming them on your return.
Does Polyconomic handle staking and DeFi?
Yes. Staking rewards are treated as income at the GBP value on the date received. DeFi transactions including swaps, liquidity provision, and yield farming are imported and categorised as correctly as possible given HMRC's published guidance.
What if my data is incomplete?
Incomplete data means an incomplete calculation. We flag any gaps in your transaction history and tell you what is missing. It is worth the effort to fill in the gaps — HMRC expects complete records.
Reports
What does the PDF report contain?
The report contains your total proceeds, total allowable costs, total gains, total losses, and a trade-by-trade breakdown of every disposal. It follows the HMRC SA108 layout.
Can I give the report to my accountant?
Yes. Download it and send it. On the Pro plan you can also give your accountant direct access to your account so they can view your data and download reports themselves.
Is the report actually accepted by HMRC?
HMRC does not accept attachments — you manually enter the figures from the report into your Self Assessment return (SA108). The report gives you every number you need to do that.
Can I get reports for previous tax years?
Yes. Both Standard (£49/year) and Pro (£99/year) cover every tax year in your account, including previous years.
Pricing and billing
Is it really free to see my gain?
Yes. Import your transactions, and you can see your taxable gain for every tax year — for free. No card required. You only need a paid plan to download the PDF report.
What is the Standard plan?
Standard is £49 per year. It includes full SA108-compatible PDF reports for all tax years, auto-recalculation when you add transactions, and supports up to 10,000 transactions.
What is the Pro plan?
Pro is £99 per year. It includes everything in Standard plus unlimited transactions, accountant sharing (so your accountant can access your data directly), CSV export of all your transactions, and priority support.
Can I get a refund?
If you have not yet downloaded any reports and would like to cancel within 14 days of subscribing, contact us and we will sort it out. We want every subscription to be useful.
