How to Download KuCoin CSV & Export API?
If you are a casual crypto investor or a seasoned trader and have used KuCoin, you will need to report your crypto activity to HMRC. To do that, you must first collect your transaction history, and KuCoin provides two main ways to do this: via CSV files or API export.
Let the Crypto Accountants walk you through both methods in a simple, beginner-friendly way, while also covering what kind of data HMRC needs, which tools work best, and how to make your tax reporting process smoother.
Why Exporting Your KuCoin Data Matters?
In the UK, crypto is subject to tax just like any other investment. HMRC expects you to report capital gains, losses, income from staking, airdrops, or crypto payments.
But here’s the challenge: KuCoin doesn’t send tax reports to HMRC on your behalf. It’s up to you to get your own records, which means downloading your trade history, funding activity, and earnings. Without complete and accurate data, your tax report may be incorrect, leading to fines or audits.
This is where CSV and API exports come in. With them, you can feed your transaction history into tax tools like Koinly, CoinTracker, or your accountant’s software. Let’s go through both methods, one by one.
Method 1: CSV Export from KuCoin
A CSV file is a downloadable spreadsheet containing your transaction data. It’s a great option if you prefer a one-time export or don’t want to share API keys.
Step-by-Step Instructions
- Log In to KuCoin: Visit www.kucoin.com and log into your account with your email and password.
- Go to Trade History: Once logged in, hover over Orders in the top menu, and click on Spot Order History. You can also check Funding History for peer-to-peer or wallet transfers.
- Choose Your Date Range: Set a custom date range that includes the full tax year. For UK taxpayers, this is usually 6 April to 5 April of the following year. If you are preparing for the 2024–25 tax year, choose 6 April 2024 to 5 April 2025.
- Export to CSV: Click on the ‘Export to CSV’ button. Wait a few seconds — KuCoin will generate a downloadable file. Save this file on your computer.
- Repeat for Other Data Types: Don’t forget to also export your withdrawals, deposits, and funding transactions. HMRC looks at all types of activity, not just trades.
Pros of CSV Export
- No tech skills required
- Quick and simple
- Ideal for occasional traders
Method 2: API Export from KuCoin
An API (Application Programming Interface) allows tax software to connect directly to your KuCoin account. This method is more automated and updates your transaction data regularly.
- Sign In to KuCoin: Head to the official site and log into your account.
- Access API Management: Click your profile icon in the top-right corner, then select API Management from the dropdown menu.
- Create API Key
- Click Create API
- Give it a name like “Koinly” or “Tax Software”
- Set a passphrase (a password you’ll need later)
- Make sure to enable Read-only access, never allow withdrawal access for safety reasons.
- Copy Your Credentials: KuCoin will give you three things:
- API Key
- API Secret
- Passphrase
- Save these securely. You’ll need them to connect to your tax software.
- Link with Tax Tool: Head over to your tax platform (e.g., Koinly) and enter the API details. It will start pulling in your data automatically.
KuCoin exports often miss cost basis on older trades, which quietly inflates your gain. Specialist crypto tax accountants reconcile the gaps before the figures reach HMRC.
Pros of API Export
- Real-time updates
- Less manual work
- Useful for high-volume traders or ongoing activity
KuCoin exports are among the messiest we deal with, particularly once futures and staking are involved. If yours will not reconcile, our London-based crypto tax team can rebuild it for you.
What HMRC Wants From You?
In the UK, HMRC treats crypto as property, not currency. That means:
- You pay Capital Gains Tax (CGT) when you sell, swap, or use crypto for payments.
- You might owe Income Tax for staking rewards, mining, airdrops, or token payments.
- You must keep records for every transaction, price, date, fees, asset, and quantity.
If your KuCoin data is incomplete or inaccurate, your tax report could trigger questions from HMRC. That’s why using export tools properly is key.
Which Tax Tools Work with KuCoin?
Popular platforms that support KuCoin via both CSV and API include:
- Koinly (UK-friendly, auto-detects income types)
- CoinTracker
- Accointing
- TokenTax
- Crypto Tax Calculator
All of these let you upload CSV files or connect via API. Just make sure you double-check categorisation for staking, DeFi, and P2P transfers, as these may need manual input.
Suppose you bought ETH on KuCoin in July 2023 and sold it in March 2024, making a £3,000 profit. You also earned £500 in staking rewards.
You would need:
- Trade CSV showing purchase and sale
- Funding/export showing deposit and withdrawal (if relevant)
- Staking CSV or API export
This data lets your tax tool calculate:
- £3,000 capital gains (subject to CGT)
- £500 income (subject to Income Tax)
If you hold for more than 12 months, you may be eligible for certain reliefs or exemptions depending on future HMRC guidance.
Common Mistakes to Avoid
- Only exporting trades (forgetting deposits, staking, etc.)
- Using wrong date ranges (e.g., calendar year instead of tax year)
- Ignoring small transactions (even NFTs and swaps count)
- Uploading incomplete CSVs or expired API keys
Stay organised and check regularly, KuCoin only allows export of recent data for certain activity types.
Final Thoughts
Exporting your KuCoin transaction history is essential for accurate UK tax reporting. Whether you go with a CSV file or set up an API key, make sure your data is complete and well-organised. This helps you stay compliant with HMRC rules — and saves you a headache later.

People Also Ask
Do I need both CSV and API from KuCoin?
Not necessarily. Choose one method based on your comfort. CSV is manual but simple. API is automated but needs setup.
Is KuCoin regulated in the UK?
No, KuCoin is not FCA registered. This doesn’t affect your tax obligations — HMRC still expects you to report all activity.
Can I use KuCoin data in Koinly for free?
Yes, you can connect KuCoin for free in Koinly. But you’ll need a paid plan to generate HMRC-ready tax reports.
What if I made no profits?
Even if you made a loss, you should report it. You can carry crypto losses forward to offset future gains.
How often should I export my data?
Best practice is to do it quarterly or at least once per tax year. Don’t wait until April.
