Do Sub-Account Fees Earn a Rebate? 2026 Sub-Account Referral Rules by Exchange

Whether a sub-account's trading fees earn a rebate depends on whether the exchange spells it out. Binance and BingX state it clearly: commission on fees paid by a sub-account goes to the main account's referrer. Bybit only says, in its regular referral program explainer, that trades from sub-accounts, copy trading accounts and bot accounts count; its affiliate program explainer doesn't say. OKX only says that trades in managed sub-accounts earn no rebate, with nothing written for regular sub-accounts. Gate, Bitget, MEXC and KuCoin say nothing in their referral and affiliate explainers about who sub-account fees count toward. Bybit and MEXC also state that only the main account can add a referral code later, not a sub-account (verified October 2026).

A common misunderstanding is that every sub-account needs its own referral code and its own UID binding. On the exchanges that say anything, the referrer follows the main account: Binance and BingX credit sub-account commission to the main account's referrer, and Bybit and MEXC only let the main account add a code later. So when you bind for a rebate, submit the main account's UID. What goes wrong more often is the order of steps: the main account skipped the referral code, then sub-accounts were opened, connected to an API and started running strategies, and by the time you think of binding, the add-later deadline has passed. A sub-account can't add a code itself, so the only fix is through the main account, and the fees already paid won't earn a rebate.

"Not stated" means that none of the referral, affiliate and sub-account pages we checked mention the point, not that the exchange doesn't count it. On those exchanges, whether sub-account fees reach your rebate is shown in Fee Otter's daily settlement records.

Is binding the main account's UID enough?

When you bind for a rebate, submit the main account's UID. Sub-accounts sit under the main account, and Binance and BingX state that sub-account commission goes to the main account's referrer, so you don't need to submit each sub-account's UID.

A few cases need separate handling:

• Separately registered accounts: an account registered with a new email or phone number is another main account with its own referrer. Enter the referral code when you register it, then bind its UID on Fee Otter.
• OKX managed sub-accounts: OKX states they earn no rebate, so binding the main account doesn't change that.
• Exchanges that don't say: if you trade mainly in a sub-account, place one small order there first, then check the settlement records on the rebate site the next day to see whether that fee shows up. If it doesn't, contact support to check where it was credited.

What goes wrong if sub-accounts come before the referral code

The common mistake in order goes like this: the main account registered without a referral code, a few sub-accounts were opened, APIs were connected and bots started running, and only later did the rebate come to mind. At that point three things happen.

• A sub-account can't fix it on its own. Bybit states only the main account can add a code later, and MEXC's self-service referrer binding is limited to main accounts. Binance sub-accounts can't even invite new users. Any fix has to come from the main account.
• Adding a code later has a deadline. If the main account is still within the window and has no referrer yet, it can add one: Binance 30 days (no deposit and no trade yet), MEXC 30 days, Bybit 14 days. OKX, Gate and Bitget have no public way to add one later. After the deadline, the main account can only be rebound; see the add-later and rebinding rules table for each exchange's method.
• Rebinding means a new main account. Most rebinding methods mean registering a new account with the referral code. Sub-accounts under the old main account don't move with you; you have to reopen them under the new main account, recreate the API keys and set the strategies up again.

One more point: no exchange says whether sub-accounts created before the main account added a code will count for the new referrer. After adding the code, place a small order in a sub-account and check the rebate site the next day.

The right order is: register the main account with the referral code, bind the main account's UID on Fee Otter, then open sub-accounts and start trading. Also, Fee Otter's extra rebate only counts fees generated after the UID is bound, and nothing is paid back for earlier fees; the exchange's automatic rebate starts from sign-up with the referral code.

Worked example: three accounts trading together

Say you trade on Binance with one main account and two sub-accounts, and the main account was registered with the referral code and its UID is bound. One month's trading fees:

Calculation: rebate = total fees of the three accounts × rebate rate. Binding Binance through Fee Otter gives 40%, in two layers:

• Binance automatic rebate, 20%: 220 × 20% = 44 USDT, refunded by Binance straight to your account.
• Fee Otter extra rebate, 20%: 220 × 20% = 44 USDT, which builds up on Fee Otter and is withdrawn over BEP20. The 0.015 USDT network fee is paid by you, so you receive 44 − 0.015 = 43.985 USDT.

That is 88 USDT in total, or 87.985 USDT after one withdrawal network fee.

Now suppose sub-account A's bot ran for 10 days before the main account's UID was bound and paid 50 USDT in fees. Because the main account was registered with the code, Binance's automatic 20% still comes back, but those 50 USDT get no Fee Otter extra rebate, so you miss 50 × 20% = 10 USDT. If the main account had no referral code at all, you would get neither layer.

How to choose

• Not registered yet: register the main account with the referral code, bind the main account's UID, then open sub-accounts.
• Main account exists without a code, still within the add-later window: add the code from the main account, not from a sub-account. Then bind the main account's UID.
• Past the window, or the main account already has another referrer: follow the exchange's rebinding method to open a new main account with the referral code, then reopen sub-accounts under it.
• Strategies spread across several accounts: use sub-accounts where you can, so you only bind one UID. Each separately registered account needs its own referral code and its own binding.
• Mainly OKX managed sub-accounts: that part earns no rebate; rebates only come from accounts you trade yourself.

Risks and things to watch

• Rules may change: sub-account rules are spread across referral, affiliate and sub-account pages, each updated at different times. BingX's sub-account FAQ was published in 2023 and Gate's sub-account guide in 2022.
• Referral and affiliate programs are two sets of rules: the Bybit text that mentions sub-accounts is the regular referral program explainer. Fee Otter is a Bybit affiliate partner, and the affiliate program explainer doesn't mention sub-accounts, so go by the settlement records.
• No fee paid, no rebate: for zero-fee pairs and fees covered by vouchers or trial funds, most exchanges pay no commission. The same applies to sub-account trades.
• Limits on multiple accounts per person: OKX and Bitget allow only one verified main account per identity, and recommend sub-accounts if you need several trading accounts. Check each exchange's identity rules before registering another account.

FAQ

Do I need to bind each sub-account's UID?

No. Bind the main account's UID. Only separately registered accounts need their own binding. On exchanges that don't say where sub-account fees go, place one small order and check the settlement records the next day.

Can a sub-account enter a referral code itself?

No. Bybit states only the main account can add one later, MEXC's self-service binding is for main accounts only, and Binance sub-accounts can't invite new users. Other exchanges don't say.

Do OKX sub-account trades earn a rebate?

Trades in managed sub-accounts don't; OKX states this. For regular sub-accounts, OKX's affiliate rules say nothing specific, so go by the settlement records.

If a sub-account runs an API or trading bot, do its fees count?

Binance's referral terms pay commission on fees actually paid, without distinguishing how orders are placed. Bybit's referral program explainer states copy trading accounts and bot accounts count. Other exchanges don't say.

Does sub-account volume help the main account reach a higher VIP level?

Gate states sub-account volume counts toward the main account and sub-accounts use the main account's VIP level. OKX sub-accounts use the main account's fee tier. For Binance, Bybit and Bitget, see the exchange VIP tiers comparison.

My main account already has someone else's code. Can a new sub-account switch to Fee Otter?

No. On Binance, sub-account commission goes to the main account's existing referrer, and on Bybit and MEXC sub-accounts can't bind their own referrer. The only way to switch is to open a new main account using each exchange's rebinding method.
