Terms of Service

ChainTax is a tax calculation tool that sorts on-chain DeFi transactions and generates estimated UK tax reports.

ChainTax does not provide financial, legal, or tax advice. The figures generated are estimates based on on-chain data and published HMRC guidance. You are responsible for verifying all figures with a qualified tax adviser before filing any tax return.

You must be at least 18 years old and a UK tax resident to use ChainTax. By creating an account, you confirm that you meet these requirements.

• •You are responsible for maintaining the confidentiality of your account credentials.
• •You must provide accurate information when creating your account.
• •You may not share your account or create multiple accounts.
• •Each ChainTax account is intended for one person’s personal tax position. Each plan includes a generous wallet allowance scaled to its tier; if you have a legitimate reason to add more wallets (multiple personal addresses, lost-key recovery, cold storage rotation), email hello@chaintax.co.uk and we’ll bump your limit.
• •Preparing crypto tax reports for clients or third parties requires our accountant plan. A personal account may not be used to run reports for multiple individuals or for any commercial tax-preparation service.
• •We may suspend or terminate accounts that violate these terms.

• •Free tier — Classify up to 200 transactions. Report download requires a paid plan.
• •Light (£49) — Up to 2,500 transactions per tax year.
• •Active (£99) — Up to 10,000 transactions per tax year.
• •Concierge — Above 10,000 transactions — email hello@chaintax.co.uk for a fixed-price quote. We run the sync and deliver the report.

Plans are one-time payments per tax year, not subscriptions. Prices may change — any change applies to new purchases only. Existing purchases are honoured at the price paid. You may upgrade within a tax year; upgrades are charged at the price difference.

Concierge sync: For wallets above the 10,000-transaction self-serve cap, ChainTax offers a manual Concierge sync — quoted on a per-portfolio basis via hello@chaintax.co.uk. When you request a Concierge sync and pay the agreed quote, you authorise ChainTax to access on-chain transaction history for the public wallet addresses you supply, generate the report on your behalf, and provide 14 days of email support. We never request private keys, seed phrases, or exchange API credentials. Concierge data is stored on an internal service account and can be deleted on request once the report is delivered and the support window closes. See the Concierge service page and Privacy Policy for full detail.

Payments are processed by Stripe. ChainTax does not see or store your card details. All prices are in GBP and inclusive of VAT where applicable.

Refund policy: Under the UK Consumer Contracts (Information, Cancellation and Additional Charges) Regulations 2013, you have a 14-day right to cancel a digital content purchase. However, once you download a tax report, you acknowledge that digital content has been delivered and your right to cancel is waived.

• •Report not yet downloaded: full refund available within 14 days of purchase.
• •Report downloaded: cancellation right is waived. No refund available.

If you experience a technical issue preventing service delivery, contact hello@chaintax.co.uk within 14 days of purchase.
