Koinly Affiliate Program Review

Koinly is a crypto tax calculator and portfolio tracker: users connect exchanges and wallets, and Koinly produces tax reports for their country. Creating an account is free; the commission comes from paid tax plans. That makes it an easy recommendation for any crypto audience, especially in the weeks before a filing deadline.

The Koinly affiliate program pays a cut of those paid plans. The deal is simple, but there are three wrinkles worth understanding before you apply: a per-order cap, a 30-day lock with refund clawbacks, and a fuzzy line between the affiliate program and Koinly’s Refer-a-friend scheme.

How the Koinly affiliate commission works

Koinly’s affiliate page advertises 20% commission. You earn only when a referred customer pays for an eligible tax plan — free sign-ups do not count. The per-order commission is capped at the lower of the amount the customer paid or $150.

Here is what the cap means in practice:

The table is arithmetic on Koinly’s published rule, not a quote of plan prices. The takeaway: the cap only bites on orders above $750. If your audience is mostly hobby investors buying entry-level plans, you will rarely hit it. If you serve high-volume traders or funds, expect the cap to flatten your best sales.

Refunds are deducted from your balance, and commissions are locked for 30 days after they are earned. That lock is long enough to cover most refund requests, so what you see after 30 days is close to final.

What about the “up to 40%” figure?

You will see “up to 40%” in older Koinly materials and in third-party directories. Some directories also report “20% on the first purchase, 10% on repeat purchases”. Neither is confirmed on Koinly’s current official pages. We treat 40% as historical or a negotiated top-performer rate, and repeat-purchase terms as not published. If you build a large audience, ask Koinly about a higher rate — but do not plan revenue around it.

Koinly affiliate program vs Refer-a-friend

Koinly runs two schemes, and choosing the wrong one costs you money.

Koinly’s terms describe the affiliate program as intended for people with large followings or networks and point smaller users to Refer-a-friend. No numeric threshold is published, so “large” is Koinly’s call.

One rule catches people out: if you switch from Refer-a-friend to the affiliate program, any unspent Refer-a-friend credits are forfeited and cannot be transferred. Spend them first.

How to join the Koinly affiliate program

1. Create a free Koinly account. You need one to access the affiliate dashboard.
2. Spend any Refer-a-friend credit. It disappears once you move to the affiliate program.
3. Apply on the affiliate page. Use the "Become an affiliate" form at koinly.io/affiliate and describe your audience: channel size, countries, and how you plan to promote Koinly.
4. Set up payouts. After approval, add your PayPal details, or ask about USDC if you prefer a stablecoin.
5. Request payouts. Once commissions clear the 30-day lock, request payment from the dashboard.

The dashboard shows your affiliate linkAffiliate link Your personal URL that tells the program a visitor came from you. Clicks and sign-ups through it are credited to your account. More, code and balance. Sub-IDs, postbackPostback A server-to-server message the program sends to your tracker when a conversion happens, so you see sign-ups and deposits as they occur. More and an API are not documented, and Koinly does not publish details on promo materials or a dedicated manager.

Getting paid

Payouts are in USD, generally via PayPal, and Koinly’s affiliate page mentions USDC as an alternative. That makes Koinly one of the few tax tools you could list among affiliate programs that pay in crypto, though PayPal is the default.

Timing is less clear than it should be. Koinly’s FAQ and terms both describe payout requests on a 30–60 day cycle, but the wording differs between pages. Combined with the 30-day lock, assume one to two months between a customer’s purchase and cash in your account.

Traffic rules and the seasonality problem

Koinly’s terms let it deactivate affiliate codes for breaches, and there is a whole help article on deactivated codes. Specific rules on paid searchPPC Paid ads where you pay each time someone clicks, like Google or Bing search ads. Crypto ads face strict platform rules. More, brand biddingBrand bidding Buying search ads on a brand's own name, such as 'Bitget login'. Most crypto programs ban it and can void your commissions. More and coupon sites are not published. Until Koinly confirms otherwise in writing, avoid bidding on “Koinly” and avoid presenting your link as a discount code.

The bigger business risk is timing. Tax software sells in waves before national deadlines — the US in April, the UK in January, Australia in October. Most of your annual Koinly income will arrive in a few weeks.

There is also competition from Koinly itself. Its own blog publishes guides on crypto taxes and even a “best crypto affiliate programs” list, so you are competing with the merchant for the same SEOSEO Search engine optimization: earning free, organic visitors from Google by publishing pages that rank for what people search. More keywords. Win on angles Koinly will not cover: comparisons with other tools, walkthroughs for specific exchanges or DeFi protocols, and local tax situations in smaller markets. Our crypto affiliate website guide covers how to structure that kind of content.

Conversion tips specific to Koinly

Tax software is bought by people with a problem, not by people browsing. Your content converts when it solves the problem first and recommends the tool second.

Start from the pain point. “How to report crypto staking income”, “what to do if an exchange shut down and you have no CSV”, “how DeFi swaps are taxed” — each of these leads naturally to a tool that imports transactions automatically. Show Koinly handling the specific case, with screenshots of the import and the resulting report.

Name the country. Koinly produces reports for many countries, but your reader cares about one. A page that says which local form or report Koinly generates beats a generic review.

Be upfront about the cost. Readers who expect a free report and then hit a paywall feel tricked and bounce. Explain that a free account is not the same as a free tax report, because the report comes with a paid plan. You will lose fewer people at checkout and cut refund requests that would claw back your commission.

Use video for imports. Connecting exchanges and wallets is the step where people get stuck. A short screen recording of the import process often converts better than a long written guide, which is why crypto creatorsKOL Key opinion leader: an influencer with an engaged audience, such as a YouTuber, an X account or a Telegram channel owner. More on YouTube tend to do well with tax tools.

Is it worth it for small sites?

Possibly not yet. Koinly says the affiliate program is for people with large followings and points smaller users to Refer-a-friend, which pays only in Koinly credit. If your site is new, CoinLedger’s self-serve program with no audience threshold is an easier first step, and you can apply to Koinly once your traffic grows. Our crypto traffic sources guide covers how to build that audience.

Who the Koinly affiliate program suits

• Crypto YouTubers and newsletter writers with an engaged audience in countries with clear tax reporting rules.
• Accountants and tax professionals who recommend software to clients.
• Communities that can run a seasonal push before filing deadlines.
• Sites with country-specific tax content that ranks in search.

It fits less well if you are small and just starting out (Koinly may route you to Refer-a-friend), or if you want income every month of the year.

Koinly vs other crypto tax affiliate programs

• CoinLedger pays 25% on every tax report a referral buys, each year they file, from a $30 minimum. Its 15-day cookie and PayPal-only payouts are the trade-offs.
• CoinTracker publishes a user referral scheme — 20% of a friend’s first-year subscription, up to $500 — while publisher terms run through third-party networks.

Verdict

The Koinly affiliate program is easy to explain to an audience and easy to forecast: 20% of each paid plan, capped at $150 per order, paid in USD via PayPal or USDC after a 30-day lock. For creators with a tax-season audience it is a natural fit.

Its weaknesses are transparency and upside. The cookie length, minimum payout and repeat-purchase terms are not published officially, the cap trims your largest orders, and CoinLedger’s recurring 25% beats it on paper for audiences who file every year. Apply if you have the audience, spend your referral credits first, and confirm the minimum payout in your dashboard.
