Examined Jul 27, 2026 Read from Koinly's live terms Crypto tax software Free plan needs no code Koinly does not publish the size of its discount, so no honest page can quote you one.
Before you hunt for a code at all, look at the free plan. Koinly's free tier needs no code, no link and no discount. If your transaction count fits inside it, the right move is to use it and stop shopping, because no referral link improves on free. A code only matters once you have to buy a paid tax plan, and even then the tier you choose moves far more money than any discount applied to it.
What pays what
| You, if your transaction count fits the free plan | Nothing to claim, and nothing to pay |
|---|---|
| You, new user on a paid plan, via someone's link | A discount, size unpublished |
| An affiliate, on a single order | Up to $200, or the order total if that is lower |
| Affiliate commission on Newbie, Hodler, Trader and Pro plans | Yes, those are the plans it runs on |
| Anything knocked off the order total by a promo code | Not eligible for commission |
| An affiliate's balance below 3 unique customers or below $100 | Cannot be requested yet |
| Credits you built up on Refer-a-friend, if you switch | Lost, and not transferable |
| Unpaid commission, if Koinly terminates the agreement | Forfeited |
The $200, the three-customer and $100 payout thresholds and the promo-code exclusion all come from the Affiliate Program Terms revised on January 1, 2026, read live on July 26. The blank in the second row is not our blank. It is Koinly's.
Do this, in this order
- Check the free plan first. Koinly's free tier needs no code and no link. Count your transactions for the tax year before anything else; if they fit the free plan you are finished.
- If you do need to pay, pick the plan tier before you pick a link. Koinly sells its tax plans by size, from Newbie up through Hodler and Trader to Pro. Getting your transaction count right is worth more than any discount applied on top of it.
- Click your friend's link before you create the account. Koinly's help pages said to sign up after clicking the link, that clicking one with an existing account does nothing, and that referral links need cookies enabled with no promo-code box to fall back on. We read that on July 24 through the tool we no longer trust, so treat it as the safe order of operations, not a verified rule. Clicking first costs you nothing either way.
- Watch the total at checkout, because that is where the number lives. Koinly sets the discount per affiliate and shows it inside the affiliate panel. If the total did not move, the link did not work.
- Do not switch programmes on a whim. The affiliate terms say: "Any credits you may have earned on other referral programs like the 'Refer-a-friend' program will be lost when you do this. It is not possible to transfer credits or referrals over." If you have a balance sitting in refer-a-friend, spend it before you go anywhere near the affiliate sign-up.
If you are the one sharing links
The cap is $200, not $150. In Koinly's words: "The maximum commission that can be earned on a single order is capped at the total amount paid by the customer or $200 USD (whichever is lower)." On a cheap plan, the ceiling is the price of the plan.
Commission runs on the tax plans only. Newbie, Hodler, Trader and Pro. "Any amount discounted from the order total due to the use of promo codes will also not be eligible for commissions." A buyer who stacks a seasonal sale shrinks your commission along with their bill.
Two thresholds, then two waits. A payout needs commissions from three unique customers and a balance of at least $100 USD. Commissions are locked for 30 days before they can be requested, and "Payment processing can take up to 60 days from the request date".
The clause that should decide whether you bother. "If Koinly chooses to terminate the agreement any unpaid commissions will be forfeited." Next to the 30-day lock and the 60-day processing window, that means your balance sits on Koinly's side of the table for up to three months, and it can be ended from that side.
Is it worth your time?
If your transaction count fits Koinly's free plan, there is no code to find and nothing here to claim, so go and count your transactions instead. If you do have to pay and someone you know has a link, click it first. It takes ten seconds and there is no downside. But do not go looking for the number, because it does not exist in public, and any site quoting you a specific Koinly discount is quoting something it cannot have read. The decision that actually costs or saves you money is the plan tier, and whether Koinly reads your exchange history properly. Spend your attention there.
