Frequently Asked Questions

At CTC, we design our product with security in mind. We follow industry standard best practices to keep your data safe.

What is the best crypto tax software for UK investors?

Crypto Tax Calculator is the top choice for UK investors because it: Complies with HMRC rules, including Bed and Breakfast and Same Day. Handles complex transactions like staking, DeFi, and NFTs. Generates HMRC-ready reports, including SA100 and SA108 forms. Integrates with popular accounting tools like QuickBooks. With automated features and a user-friendly interface, Crypto Tax Calculator simplifies tax reporting, saving you time and reducing errors. Sign up today to experience the difference!

What happens if I miss the crypto tax deadline in the UK?

In the UK, the deadline for filing Self Assessment tax returns is 31 January following the end of the tax year (e.g., 31 January 2026 for the 2024-2025 tax year). Missing this deadline can result in automatic penalties, even if you owe no tax. For instance: Late filing penalties: £100 for up to 3 months late, with additional daily penalties if delays persist. Late payment penalties: Interest accrues from the payment due date, typically 31 January. HMRC may issue higher penalties for deliberate non-compliance or underreporting. To avoid these penalties, ensure you keep accurate records and file your taxes on time. Crypto Tax Calculator can streamline this process by generating HMRC-ready reports, minimising your risk of missing deadlines.

Can I claim tax relief for crypto losses in the UK?

Yes, the HMRC allows you to offset capital losses from cryptocurrency against your capital gains, reducing your overall tax liability. For example: If you sell Bitcoin at a £5,000 loss and Ethereum at a £10,000 gain in the same tax year, you’ll only pay tax on the net gain of £5,000. Unused losses can be carried forward to offset future gains, provided they are reported to HMRC. To claim relief, include your losses in your Self Assessment tax return and maintain accurate records of transactions. Crypto Tax Calculator automates this process, ensuring all eligible losses are applied to reduce your tax burden.

How are staking rewards taxed in the UK?

Staking rewards are treated as income by HMRC and are subject to Income Tax and potentially National Insurance contributions depending if you are operating as a business or not. The taxable value is the market value of the reward in GBP at the time it is received. For example: If you earn 0.1 ETH through staking when ETH is valued at £1,500, the taxable income is £150. When you later sell or dispose of staking rewards, any profit beyond the initial value is subject to Capital Gains Tax. Crypto Tax Calculator simplifies this process by automatically separating income and capital gains calculations, ensuring accurate reporting under HMRC rules.

How do I calculate crypto taxes for airdrops and forks?

Airdrops and forks can be taxed differently depending on the circumstances: Airdrops: If received without any actions, they are subject to Capital Gains Tax at disposal. If earned through tasks, they are treated as income at the time of receipt, with CGT applying at disposal. Hard forks: Assets received through a fork are subject to Capital Gains Tax when disposed of. The cost basis is calculated based on the market value of the forked tokens at the time of receipt. Crypto Tax Calculator tracks these complex events, applying the correct HMRC rules for each scenario, and helps ensure compliance with UK tax regulations.

How can I reduce my crypto taxes?

To legally minimise your crypto taxes in the UK, consider these strategies: Utilise the annual CGT allowance: For the 2024-2025 tax year, the first £3,000 of gains are tax-free. Offset losses: Report capital losses to reduce your overall tax liability. Losses can also be carried forward. Tax-efficient planning: Consider tax-loss harvesting, where you sell underperforming assets to offset gains. But beware of the bed and breakfast rule which is designed to prevent wash sales. Use crypto tax software: Tools like Crypto Tax Calculator help identify opportunities to reduce taxes while staying compliant. Crypto Tax Calculator simplifies tax-saving strategies, including loss tracking and allowance optimisation, ensuring you pay only what's necessary.

Do I need crypto tax software for the UK?

Crypto tax software is advisable for UK investors due to the complexity of HMRC tax rules. For example: The Same Day Rule requires all crypto transactions on the same day to be grouped for calculating the average cost basis. The Bed and Breakfast Rule adjusts gains when crypto is sold and repurchased within 30 days. Manually applying these rules can be error-prone and time-consuming. Crypto Tax Calculator automates the process, calculating taxes accurately while ensuring compliance with HMRC regulations. It also provides HMRC-ready reports, making tax filing faster and more efficient. Alternatively, use our guide on How To Calculate Your Crypto Tax in The UK if you want to calculate your taxes manually.

Does Crypto Tax Calculator support HMRC rules like Bed and Breakfast and Same Day?

Yes, Crypto Tax Calculator is designed to comply with HMRC-specific rules such as the Bed and Breakfast Rule and the Same Day Rule: Same Day Rule: Automatically groups transactions made within the same day and calculates the adjusted cost basis. Bed and Breakfast Rule: Identifies disposals and repurchases within 30 days, adjusting gains or losses accordingly. By automating these calculations, the software reduces errors and ensures your tax reports meet HMRC standards. Generate detailed tax summaries with just a few clicks and save time during tax season.

Does Crypto Tax Calculator software track both income and capital gains taxes?

Yes, Crypto Tax Calculator tracks both Income Tax and Capital Gains Tax (CGT). It categorises transactions based on their tax type: Income Tax: Staking rewards, mining income, or payments received in crypto are calculated based on the market value at receipt. CGT: Disposals like selling or swapping crypto are calculated using HMRC’s average cost basis method. Crypto Tax Calculator simplifies tracking by separating income and capital gains events, ensuring compliance with HMRC rules. It also generates comprehensive reports that include both types of tax liabilities, ready for inclusion in your tax return.

Can Crypto Tax Calculator generate HMRC-ready tax reports?

Yes, Crypto Tax Calculator generates tax reports that are fully compliant with HMRC requirements, including: SA100 (Self Assessment Tax Return): Summarizes income, including crypto earnings, for reporting to HMRC. SA108 (Capital Gains Summary): Breaks down disposals, showing gains or losses for each transaction. These reports are formatted for easy submission to HMRC, saving time and reducing the risk of errors. With detailed transaction records and summaries, you'll have all the information needed for a stress-free tax filing experience.

What types of transactions can Crypto Tax Calculator handle?

Crypto Tax Calculator supports a wide range of transactions, including: Trading: Buying and selling crypto on exchanges. Staking: Rewards earned from staking activities. Mining: Income from mining cryptocurrencies. Airdrops: Tokens received through promotional events. NFTs: Buying, selling, and holding non-fungible tokens. DeFi activities: Including lending, borrowing, and liquidity pools. The software identifies taxable events, applies HMRC rules, and calculates both income and capital gains for accurate tax reporting.

Can I use Crypto Tax Calculator for previous tax years?

Yes, Crypto Tax Calculator supports retroactive calculations for prior tax years with a single subscription, helping you: Correct missed or inaccurate filings. Report gains and losses from earlier transactions. Carry forward unused capital losses to offset future gains. The software ensures compliance with historical HMRC rules and generates reports tailored to the tax regulations of the relevant year. Whether you're catching up or filing amended returns, Crypto Tax Calculator simplifies the process.

What crypto tax software integrates with accounting tools like QuickBooks?

Crypto Tax Calculator's business product integrates with popular accounting tools like QuickBooks and Xero allowing you to: Import transaction data directly into your accounting software. Track crypto-related income and expenses alongside traditional finances. Generate consolidated reports for tax filings and business accounting. These integrations streamline bookkeeping for both individual investors and businesses, reducing administrative workload while maintaining compliance with UK tax laws.

How does HMRC track cryptocurrency transactions?

HMRC uses advanced tools and methods to monitor crypto activity, including: Exchange data: HMRC requires exchanges operating in the UK to share user data. Blockchain analytics: Sophisticated tools trace transactions across public blockchains. International cooperation: Data-sharing agreements with foreign tax authorities enhance visibility into offshore holdings. Using Crypto Tax Calculator helps ensure all transactions are accurately reported, minimising the risk of discrepancies or penalties.

Do I need to report crypto held on foreign exchanges?

Yes, UK residents must report all global crypto holdings, including those on foreign exchanges. HMRC requires: Detailed records: Include the market value in GBP of all crypto assets held. Tax on disposals: Gains from selling or swapping crypto on foreign platforms are subject to UK tax rules. Crypto Tax Calculator simplifies compliance by converting foreign transactions into GBP and applying HMRC's tax guidelines, ensuring nothing is overlooked in your report.
