When daily MCA debits are draining your account, the instinct is to make them stop. You can — but because those debits hit a business account, the rules are very different from what most articles tell you. Here is the complete picture, including the consequences you should understand first.
The short answer: You can instruct your bank to stop honoring an MCA's daily ACH debits, but because those debits hit a business account, you do not get the consumer stop-payment protections most people assume exist. Revoking the authorization stops the withdrawal mechanism — it does not cancel the debt, and on most MCA agreements it triggers a default that can accelerate the full balance and unleash the funder's collection tools. Revocation is a legal maneuver with real consequences, not a self-help button. Understand the fallout, and get professional guidance, before you touch it.
Search around and you will find plenty of pages telling you that you have "the legal right to revoke ACH authorization." That is true as far as it goes — but it leaves out the part that actually matters for a business owner. Here is what those pages skip.
When you signed your merchant cash advance agreement, you authorized the funder to pull a fixed amount from your business bank account on a recurring schedule through the ACH network — the same rails that move payroll and vendor payments. That standing authorization is what lets the funder debit you every business day without asking again.
Two things are true at once: that authorization can be revoked, and the money you owe under the contract does not disappear when you revoke it. Keeping those two ideas separate is the whole game.
This is where the widely repeated advice falls apart for business owners. Under Regulation E (12 CFR § 1005.10), a consumer can stop a preauthorized electronic debit by telling their bank at least three business days before the scheduled transfer, and the bank must honor it. Almost every "how to stop ACH debits" article quotes this rule. The problem: Regulation E covers consumer accounts. An MCA debits your business account, which generally falls outside Reg E entirely. Some courts have extended limited protections to sole proprietors and single-member LLCs, but that is an unsettled gray area, not a right you can count on.
For business-to-business ACH, the governing framework is the NACHA Operating Rules and UCC Article 4A, plus your bank's deposit and ACH agreements. Under NACHA's rules, an ACH authorization is revocable, and once the originator (your funder) is notified that you have revoked it, they are required to stop initiating debits. If they keep pulling after a valid revocation, your bank can return those entries as unauthorized.
But the return codes and timelines for business entries are far less forgiving than the consumer versions. Corporate debits carry a return window measured in a couple of banking days — not the 60 days a consumer gets. Miss it and the money is gone until you recover it another way. In short: you have a mechanism, but it is narrower, faster, and more fragile than the consumer version everyone quotes.
If revocation is the right move for your situation — and that is a real if — the steps generally look like this:
Written revocation to the funder. Put the funder on notice, in writing, that you are revoking the ACH authorization, stating the date it takes effect, and keep proof of delivery.
Written stop instruction to your bank. Give your bank a written stop-payment instruction identifying the originator, and ask what their business-account ACH agreement requires. Banks vary, and a business stop order often needs specific identifying details to catch the right debit.
Watch the return window. Because business return timelines are short, any unauthorized debit that slips through has to be flagged quickly to be returned at all.
Consider account architecture carefully. Some owners redirect revenue to a new account so a revoked funder cannot reach it. That has its own contractual and practical consequences and should not be done casually.
None of this is exotic — but the paperwork and timing have to be right, and the sequence matters.
Here is the sentence to sit with: revoking the debit does not touch the underlying obligation. You still owe the balance. What you have done is breach the payment mechanism your contract relies on — and most MCA agreements are written to treat exactly that as an event of default.
Depending on your specific agreement and state, pulling the authorization can trigger some combination of the following. Acceleration can make the entire remaining balance due at once, not just the daily amount. Where your agreement contains one and it remains enforceable in the relevant jurisdiction, a funder may move on a confession of judgment to enter judgment quickly — though several states have sharply restricted these against out-of-state businesses, so it varies. Funders typically file UCC-1 liens on your receivables and assets and can act on them. Under UCC § 9-406, a funder may send notices to the businesses that owe you money and redirect those payments, which can be more damaging than the debits themselves. If you signed a personal guarantee, the funder can pursue you personally. And account freezes and litigation are on the table throughout.
That is why experienced advisors compare an unplanned revocation to pulling a pin: it can stop the immediate bleeding while starting a much larger fire. The owners who come out ahead are the ones who revoke as one coordinated step inside a broader strategy — with the defenses to the fallout lined up first — not as a panicked solo move.
Revocation tends to make sense only when it is paired with a plan for everything that follows: a realistic view of the balance, a strategy for the funder's likely response, protection for any personal guarantee, and, where appropriate, a path toward negotiating the debt down through restructuring or settlement on specific positions. Done in isolation, it usually accelerates the exact crisis you were trying to escape.
If your daily debits are exceeding the agreed percentage of your actual receipts, there may also be a gentler lever before revocation: your agreement's reconciliation clause, which can require the funder to true up debits to real revenue. Our framework on evaluating an MCA stack walks through the questions worth answering before you take any action against a funder.
You can revoke ACH authorization on an MCA. Whether you should, and how to do it without detonating your business, depends entirely on your agreement, your state, your guarantees, and your funder. This is a decision to make with eyes open and with the right professionals in your corner.

Can I legally stop MCA daily withdrawals?
You can revoke the ACH authorization and instruct your bank to stop honoring the debits, but because an MCA hits a business account, you generally do not get the consumer stop-payment protections under Regulation E. Stopping the debit also does not cancel the debt and can trigger a default under your agreement.
Does revoking ACH authorization cancel my MCA balance?
No. Revocation stops the withdrawal mechanism only. You still owe the full balance, and revoking often accelerates it, making the entire amount due at once.
Will my funder sue me if I revoke?
It is a real risk. Many MCA agreements treat a revoked authorization as an event of default, which can lead to acceleration, UCC lien enforcement, notices to your customers, and litigation. This is why revocation is best handled as part of a coordinated strategy.
Should I just open a new bank account?
Some owners redirect revenue, but this carries its own contractual and legal consequences and should not be done without understanding how your funder is likely to respond. Get guidance first.
