Do you need a code for Koinly?

Not to try it. The free plan imports up to 10,000 transactions and shows your gains, but Koinly says it can't generate any reports. To download a tax report you buy a plan for that year, and that purchase is where a referral matters.

How big is the Koinly referral reward?

Koinly does not say in public. Its help article says that a new user who buys their first plan through a friend's link gets a credit to redeem on future purchases; the details sit inside the app. Other links can carry a discount instead, and Koinly says not all referral links offer one.

Does a link from a Koinly affiliate work the same way as a friend's?

Not necessarily. A friend's refer-a-friend link gives you a credit on future purchases. A link from Koinly's Affiliate Program may carry a discount instead, and Koinly says not all referral links offer one, so ask the person who shared it what it gives.

A Koinly referral pays a credit you spend later, and Koinly does not publish how big it is.

Worth it ifyou need a Koinly tax report, which means a paid plan: the free plan lets you import and look, but it cannot generate reports. A friend's link is worth the ten seconds, but expect a credit on a later purchase rather than money off this one, and do not plan around its size, because Koinly states it nowhere in public.

Unpublishedis the honest answer on size. What Koinly does publish is the shape: buy your first subscription through a friend's link and you get a credit, and “You can redeem credits on future purchases.”

Before you hunt for a link, know what free gets you. Koinly's free plan imports up to 10,000 transactions and shows your gains and a tax summary, but in Koinly's words it “Can't generate any reports”. To download a report for a tax year you buy a plan for that year, sized to your transaction count. That choice is what sets your price.

Two corrections. We used to say that if your transactions fit the free plan you were finished, and that a friend's link showed up as money off at checkout. Koinly's Tax plans and refer-a-friend articles say otherwise: no reports on free, and a credit for later.

Two programs share one name, and Koinly says so itself. “The Koinly Affiliate Program is best suited for people with large followings or networks.” A link from a friend is usually Refer-a-friend, which gives you a credit for later. A link from an affiliate may carry a discount, or nothing. If you are about to click a link, find out which kind it is.

What you get

You, on the free plan	Import and look; no reports
You, buying a first plan through a friend's refer-a-friend link	A credit for later, size unpublished
A link from an affiliate	Perhaps a discount; not all links carry one
A customer of Kraken, Nexo or Revolut logging in through them	A partner discount, sometimes a free plan

The blanks are Koinly's, not ours: it publishes no size for any of these. Partner customers “can enjoy hefty discounts on Koinly, sometimes even a completely free plan”, and you cannot stack them: “Discounts cannot be combined with other offers or promotions.”

Do this, in this order

Know what free gets you. The free plan is for importing and checking your numbers. If you need a report to file with, you are buying a plan for that tax year.
Pick the plan tier before you pick a link. Koinly sells yearly plans by transaction count: Newbie up to 100, Hodler up to 1,000, Trader up to 3,000, Pro up to 10,000. Getting the count right is what sets your price.
Check for a partner discount first. If you use Kraken, Nexo or Revolut, Koinly says the partner discount applies only if you log in to Koinly through the partner's site, and it cannot be combined with another discount or promotion.
Click your friend's link before you create the account. Koinly: “You should sign up to Koinly after clicking the link for the referral code to work”. With an existing account, “clicking this link will not do anything”. “Referral links require cookies enabled in your browser”, and there is no promo-code box to fall back on.
Ask what the link gives. “Not all referral links offer a discount when used. Confirm with the person who shared the link what the benefits are”. A refer-a-friend link pays a credit on future purchases, so an unchanged first total does not mean it failed.

Is it worth your time?

If you only want to see your gains, the free plan does that and no link improves on free. If you need a report, you are paying, and a friend's link costs ten seconds and has no downside; just expect the reward as credit on a later purchase. Do not go looking for the number, because it does not exist in public, and any site quoting a specific Koinly discount is quoting something it cannot have read. The decisions that cost or save you money are the plan tier, a partner discount if you have one, and whether Koinly reads your exchange history properly.

If you refer people yourself later, Koinly’s two affiliate documents disagree on the cap. Its Affiliate Program help article, dated June 5, 2026, says commission is “capped at the total amount paid by the customer or $150 USD (whichever is lower)”. Its Affiliate Program Terms, revised on Jan 1, 2026, give the same rule with $200. Plan on the lower figure. Credits you earn on Refer-a-friend are lost if you switch to it.
