About Koinly
The job Koinly does is unglamorous and genuinely useful: it turns a year of scattered crypto activity into a tax report your accountant, or HMRC, will accept. You connect your exchanges and wallets through read-only API keys or CSV uploads, it pulls in your full transaction history across 900-plus platforms and chains, and it calculates your capital gains, losses and income using the cost-basis rules for your country. For the UK that means Share Pooling, the same-day rule and the thirty-day bed-and-breakfasting rule applied automatically, with a finished HMRC report at the end.
What makes it easy to recommend is the free preview. You can connect everything, watch your gains and losses populate, and see your estimated position before paying anything, since the fee only kicks in when you download the actual report. The coverage is the widest in the category, which matters if your holdings are spread across several exchanges and a few chains, and the interface stays approachable while doing genuinely complex work underneath.
The honest qualifier is that Koinly is only as accurate as what you feed it. Connect every wallet and it's excellent; leave one out, or let a batch of DeFi transactions import mislabelled, and the numbers can be badly wrong until you fix them. It's also priced per tax year by transaction count, so it's a cost you meet again each January, and heavier traders pay more. Buy through Rewardio and you earn 10% cashback on every plan, including each year you renew, paid as real money, which quietly offsets a recurring bill.

What we like
- The widest coverage in the category, handling diversified, multi-chain and DeFi portfolios that trip up rivals, across 900-plus integrations and thousands of tokens.
- It turns a dreaded task into a roughly twenty-minute one, with a clean interface and a full gains-and-losses preview available free before you ever pay.
- Compliant, credible reporting across 100-plus jurisdictions, trusted enough that crypto accountants recommend it, backed by SOC 2, ISO 27001 and read-only account access.
Where it falls short
- It's only as good as its inputs, so complex DeFi, wrapped and bridged transactions need manual review, and a single unconnected wallet can distort the result badly.
- The per-tax-year repurchase model and transaction-based tiers mean the cost recurs and grows, with surprise overage charges a recurring complaint.
- Reviewers flag the lack of two-factor authentication on a tool wired to exchange accounts, and support can lag during peak tax season.
Our Verdict
Koinly has earned its place as the default crypto tax tool for UK and multi-country investors, and the 4.6 Trustpilot score across thousands of reviews reflects how much of the pain it takes away. The honest caveats are that it calculates rather than advises, complex DeFi still needs a human review pass, and the per-year, per-transaction pricing keeps costing you. For most investors who connect every wallet and sanity-check the figure before filing, it's the reliable choice. Bought through Rewardio, the 10% cashback comes back as real money on every plan, renewals included, softening a bill you'll meet every tax season.

Frequently Asked Questions
Answering the questions we actually get about Koinly.
How does Koinly cashback work, and is it better than a Koinly discount code?
It's the more reliable of the two. Start from Rewardio, buy any paid Koinly plan, and you get 10% of what you paid back as real money, on your first purchase and on every tax year you renew through us. We'll be straight with you: Koinly discount codes genuinely exist, and a working one can occasionally beat 10% off a single year's report. The catch is that most of those codes are expired or invalid by the time you try them, they only apply once, and a code can't be combined with cashback. So the choice is a one-off gamble on a code that may not work, or a guaranteed real-money return every year. For anyone holding crypto long term, the cashback adds up.
Is there a Koinly discount code, coupon or promo code?
Often, yes, but with a heavy asterisk. Koinly runs frequent promotions, particularly around December and the tax-season rush, and dozens of codes float around the coupon sites claiming 20 to 30% off. In practice a lot of them are dead, region-locked or never worked, so you can lose real time testing them at checkout. Cashback sidesteps all that: 10% back on every plan, guaranteed, activated just by starting from Rewardio, with nothing to paste and nothing to expire. If you do find a legitimate Koinly code that beats it on a one-off purchase, use that instead, since the two can't be stacked.
How much does Koinly cost in 2026?
It's priced per tax year by how many transactions you have. There's a free tier for tracking and previewing your gains, then paid plans to download the report: roughly Newbie at $49 for 100 transactions, Hodler at $99 for 1,000, Trader at around $179 to $199 for 3,000, and Pro near $279 for 10,000, with custom pricing above that. Go over your tier and you pay a small overage per additional 1,000 transactions. UK prices show in GBP and shift with promotions. Because it's per tax year, you buy again each season, and for most people the Hodler plan is the sweet spot.
Is Koinly safe and legit?
It's a well-established, widely trusted platform: over a million users, SOC 2 and ISO 27001 certified, GDPR compliant, and it connects to your exchanges through read-only API keys that cannot move or trade your funds. The one fair criticism reviewers raise is the absence of two-factor authentication on your Koinly login, which is a genuine gap for a tool tied to your financial accounts, so use a strong, unique password. Beyond that, its reputation among both everyday investors and professional crypto accountants is strong.
Does Koinly file my crypto taxes with HMRC, or just calculate them?
It calculates and reports, but it does not file. Koinly produces the HMRC-compliant figures and a downloadable report, applying the UK's Share Pooling, same-day and 30-day rules, and you (or your accountant) then use those numbers on your Self Assessment. It's software, not a tax adviser, so for anything genuinely complex, treat its output as an accurate starting point and get a professional to confirm it before you file.
Is Koinly accurate, especially for DeFi?
Its capital-gains engine is accurate when its data is complete, which is the important condition. Standard exchange trades and common transactions import cleanly. Complex DeFi activity, wrapped tokens, liquidity-pool migrations and cross-chain bridges often need manual review and reclassification, and a wallet you forget to connect can throw the whole picture out. Koinly flags ambiguous items rather than guessing, but it relies on you to resolve them, so build in a review pass before you trust the final number.
Koinly vs CoinTracker, CoinLedger and CryptoTaxCalculator, which is best?
Koinly's strengths are the broadest integration coverage and a genuinely generous free tier, which is why it suits diversified, multi-chain portfolios. CoinLedger tends to win on tax-software integrations and is often praised for support. CoinTracker leans tightly into exchange partnerships, and CryptoTaxCalculator is favoured by some for intricate DeFi handling. For most UK and multi-country investors wanting wide coverage and easy reporting, Koinly is the safe default; if your portfolio is DeFi-heavy, it's worth trialling a specialist alongside it.
What are the real downsides of Koinly?
Three worth weighing. The pricing recurs and climbs, since you repurchase each tax year and pay more as your transaction count rises, with overage charges catching some people out. Complex transactions need hands-on review, because DeFi and bridged activity don't always classify themselves correctly. And there's no two-factor authentication, plus support can slow noticeably during the peak filing weeks. None of these undermines the core product, but they're real.
Who is Koinly best for?
UK and international crypto investors who want an accurate, compliant report without building a spreadsheet from scratch, especially anyone spread across several exchanges and chains. Active multi-chain traders get a lot from it, provided they add a review pass before filing, and it's a firm favourite with crypto-focused accountants managing client portfolios. It's a weaker fit if you want a done-for-you filing service, or if your activity is so DeFi-heavy that you'd need a specialist to reconcile it anyway.
When does my Koinly cashback pay, and does it apply every year?
It appears in your Rewardio account within about 24 hours of your purchase, then becomes withdrawable once Koinly confirms the payment and the standard hold clears, usually 30 to 60 days, which covers the refund window. It's paid out as real money. And yes, it applies to every plan you buy through Rewardio, so each tax year you come back and renew, you earn another 10%.
