ZenLedger vs. Koinly

ZenLedger or Koinly? We’re comparing two of the leading crypto tax calculators, so you can better understand their differences.

We’ll look at integrations, automations, tax accuracy, and international support to help you pick the best crypto tax software for your needs.

Integrations

Manual imports are time-consuming, so it’s important to find tax software with more native support for your exchanges, wallets, or blockchains.

With over 1,000 supported platforms and more than 500 automatic API connections, Koinly leads in integrations. Many users can sync their accounts without having to handle any CSV files.

ZenLedger has around 130 auto-sync integrations, which means it relies heavily on manual imports. Although it does support standard formats from major exchanges, this can easily add up to a lot of extra manual work if you’re an active trader.

Portfolio tracking

Koinly and ZenLedger both feature portfolio trackers to better understand your investments and their performance. This includes highlighting unrealized gains and losses, real-time market data, and providing tax loss harvesting solutions.

ZenLedger offers these features only through their paid plan. If you’re looking to reconcile and maximise your data for a better tax outcome, before you commit to a platform, Koinly gives you access to all these insights for free. They also offer a free NFT dashboard to view your NFTs in the app and see your total asset value and unrealized gains/losses.

DeFi, NFTs, margin trading, and derivatives

Both platforms offers full range of transaction types, including: DeFi, margin trading, derivatives, lending, mining and staking income, and airdrops. However, Koinly stands out with superior DeFi support for investors.

If you’re a degen looking for a platform that can handle the chaos of DeFi and calculate your taxes correctly, Koinly supports over 3000 DeFi protocols across Ethereum, Solana, Binance Smart Chain, Polygon, and other EVM-compatible chains. ZenLedger also provides DeFi support across these popular chains, but only for 100+ DeFi protocols.

Free plan

Both Koinly and ZenLedger operate on a freemium model, but Koinly’s is far more generous. All of Koinly’s features, excluding the ability to download your tax report, are available on its free plan. Nothing is locked behind paywalls, so you can be happy with how Koinly works before purchasing a plan.

Although ZenLedger offers a free plan, many features, including tax loss harvesting and a full tax summary, require a paid plan to access.

Paid plans

For the cheapest paid plan, Koinly and ZenLedger work out the same at $49 per year. However, when it comes to the higher tiers, Koinly works out cheaper. 

Koinly’s Trader tier for up to 10,000 transactions is $199 per year, whereas ZenLedger’s Platinum plan for up to 15,000 transactions is $399 per year.

Usability and features

Both products feature automatic error detection, transaction filters, and tags, but Koinly offers a lot more support.

With Koinly, you have access to a wider range of filters, making it easier to navigate your transactions and find the data you need. It also handles automatic tagging much better, especially when it comes to spam tokens. 

Koinly is better at identifying and filtering out spam automatically, keeping your data clean. On ZenLedger, the onus is on you to manually tag spam tokens, which can add up to a lot of work.

Koinly also stands out when it comes to visibility and control. It flags errors at a wallet level and provides in-app guidance to help you resolve them quickly. You can also preview your full tax summary and adjust tax settings freely, depending on your approach.

Customer support

ZenLedger has an average 2.8-star rating on Trustpilot, with just over 90 reviews, with a number of them referring to customer support being minimal and/or unhelpful.

In contrast, Koinly is more established with an average 4.6-star rating from 2,200+ reviews, with many mentioning Koinly’s customer support staff as helpful and offering fast replies.

Both platforms offer email and live chat support, a help center, and an option for expert review. Koinly’s expert reviews are priced between $499 to $1,999, depending on the season. ZenLedger’s plan works a little differently, offering a 60-minute consultation for $275, or a premium prepared plan starting at $2,800.

Reputation and security

Both platforms benefit from strong partnerships across the industry. Notable names from ZenLedger partnerships include eToro, MetaMask, and BitPay. Likewise, Koinly is paired with some leading crypto businesses, including MetaMask, Binance, and Nexo.

When it comes to security, Koinly is SOC 2 and ISO 27001 certified and has not suffered any direct data breaches to date. In 2025, they were impacted by a third-party Mixpanel data breach, but not directly compromised, and have since discontinued use of the service. 

ZenLedger is SOC 2 certified, but unfortunately suffered a data breach in 2023 due to a third-party vendor. The data leaked included names, addresses, email addresses, and phone numbers, and ZenLedger had to warn users of potential phishing attempts.

Supported Countries 

Both Koinly and ZenLedger offer excellent support for US users, including dedicated IRS forms such as Form 8949, Schedule D, and Schedule 1, and reports you can upload directly into your preferred tax filing solution like TurboTax or TaxAct. They also both provide CRA Schedule 3 forms for Canadian users.

When it comes to international reporting, Koinly offers much more support, with dedicated reports for the UK, Australia, and across Europe. Should a country-specific report not be available, Koinly provides a Complete Tax Report with the information you need to file locally.

ZenLedger has limited support for users outside of the US and Canada, as it only offers generic gains, income, and end-of-year valuation reports for international users.

Conclusion: Which is better?

While ZenLedger offers fair support for large crypto exchanges and a similar price point for low-volume investors, Koinly is the better choice with a feature-packed freemium model, better pricing, superior customer support, and more integrations and international support. While we might be biased, we think Koinly is better suited to the majority of investors, and we'll keep working hard to keep our product that way.
