Your facility letter, not the bank's goodwill, decides what happens when a payment would take your business account past its overdraft limit. What the bank can do at that moment, whether it counts as a breach, how lenders read it later, and what to do in the first week.
Quick Answer
Going over an arranged business overdraft limit means the bank can decline the payment or allow it at its discretion, usually with extra interest or fees on the excess, and repeated excesses can trigger a review of the facility. Your facility letter decides what the bank can do, and the gap between your credit limit and your drawn balance is what every payment is tested against. If the excess keeps happening, the limit itself is usually the problem, and a business line of credit or a resized overdraft is the structural fix.
Also called: exceeding your overdraft limit, overdraft excess, over-limit. All describe a drawn balance past the approved limit.
What is the difference between your overdraft limit, drawn balance and available funds?
Your approved limit is the most the bank has agreed your account can go below zero, your drawn balance is how far below zero it sits right now, and your available funds are the gap between the two. Approved limit, drawn balance and available funds are the three numbers that decide whether a payment goes through, and most owners only watch one of them.
Interest is typically charged on the drawn balance only, not on the unused part of the limit, although some facilities also carry a line fee on the full limit, which varies by lender. The credit limit on an overdraft is set at approval and reviewed over time. How a bank arrives at that number in the first place, and what moves it, is covered in our guide to a bank overdraft limit that is too small.
The example below follows one business account across a working week. The figures are round numbers chosen for illustration, example only, and do not reflect any lender's terms.
| Day | Event (approved limit $50,000, example only) | Drawn balance | Available funds | Over the limit? |
|---|---|---|---|---|
| Day 1 | Account drawn to cover last week's wages | $30,000 | $20,000 | No |
| Day 2 | Supplier payment of $15,000 clears | $45,000 | $5,000 | No |
| Day 3 | A $9,000 payment is presented, which would take the balance $4,000 past the limit | $45,000 (payment held) | $5,000 | Would be, if honoured |
| Day 4 | The bank honours the payment at its discretion after the owner calls | $54,000 | $0 | Yes, by $4,000; over-limit charges may apply |
| Day 5 | A customer deposit of $12,000 lands and clears the excess | $42,000 | $8,000 | No |
Notice that available funds hit zero before the excess appears. The useful daily check is not the balance, it is how much room is left against the payments due before the next deposit lands.
Can you go over your business overdraft limit?
You can go over your business overdraft limit only when the bank chooses to let a payment through, because an excess is never a right that comes with the facility. Your facility letter sets the approved limit and usually says the bank may, but does not have to, honour a payment that would exceed it.
Banks handle this differently. Some decline anything past the limit automatically, while others review larger or scheduled payments case by case, and the answer can change from one month to the next. A business sitting over an arranged limit is in a different position from a business that has gone negative on an account with no overdraft at all, which carries its own rules and is treated as a separate case.
If you need regular headroom above your limit, the fix is a facility sized to your real cashflow, not reliance on the bank's goodwill each time a big payment lands.
What happens when a payment would take you over the limit?
When a payment would take you over the limit, the bank either declines it or lets it through, and a payment honoured at the bank's discretion usually costs you extra on the excess. Which way it goes depends on the bank, the size of the excess and how the account has been run.
A declined payment is returned to whoever presented it. A supplier direct debit, a payroll file or a loan repayment can bounce, and the bank may charge a fee for returning it. A payment that is allowed through puts the account over an arranged limit, and the excess typically attracts over-limit interest and fees, which vary by bank, until it is cleared.
If your account has no arranged overdraft at all, the rules are different; see what happens when a business account goes negative without an overdraft.
Which payments are most likely to tip the account over?
Scheduled payments that land on the same day as the balance peaks are the usual trigger. Direct debits for loan repayments, insurance and payroll are often presented before incoming deposits clear, so an account that looks fine at the end of the day can briefly sit past its limit in the morning. Knowing which debits are scheduled, and when, is the cheapest protection there is.
Is going over your limit a breach of your facility?
Whether going over your limit is a breach depends on your facility letter, but a one-off excess the bank chose to honour is rarely treated the same way as an excess left sitting there unresolved. The wording of your own terms decides it, not general practice.
Most business facility terms list events the bank can treat as a default. Exceeding the limit, and not clearing the excess when asked, is commonly one of them. A default event can give the bank rights to review, reduce or call in the facility, which is the path covered in our guide to a recalled overdraft facility.
Read the default and review clauses before you speak to the bank, so you know what it can and cannot do under your terms. If you think fees were charged or your limit was changed outside your facility terms, ask your solicitor to read the facility letter before you respond to the bank.
Can the bank cut or review your limit after you go over it?
The bank can review your limit after you go over it, and depending on your terms it may reduce it, but for small business customers of subscribing banks the industry code sets commitments about how that is done. A review is not automatic after one excess, but repeated excesses make one more likely.
The 2025 Banking Code of Practice applies to banks that subscribe to it and includes commitments to small business customers about notice and how changes to lending facilities are handled. The detail, including notice periods and the exceptions that apply, is covered in our guide to business loan protections. If a review ends in a cut, the options are set out in the guide to a reduced overdraft limit.
Most non-bank lenders are not bound by the Banking Code, although some follow other industry codes, so with a non-bank facility the contract terms usually carry more of the weight. Either way, a conversation before the review starts usually goes better than one after the decision is made.
How do lenders read time near or over your limit when you apply for new finance?
Lenders read time near or over your limit as a sign of how tight your cashflow runs, so a pattern of excesses on your statements weighs more than any single one. From the underwriter's seat, the question is whether the facility is sized for the business or the business is living at the edge of it.
An account that sits at or just under the limit for most of the month, with occasional excesses, reads very differently from one that dips toward the limit around payroll and recovers within days. Assessors work from your bank statements, usually the most recent several months, and many also factor the overdraft into serviceability when they test a new loan. How a lender reads overdrawn days and seasonal swings in detail is covered in how lenders read business overdraft bank statements.
What helps a lender read an excess fairly?
A short written explanation helps. A brief note naming the cause of a one-off excess, such as a customer that paid late or a contract that ended, tends to carry more weight than leaving the assessor to guess. Evidence that the excess cleared quickly, and that the cause has been fixed, matters just as much.
What should you do in the first week after going over your limit?
In the first week after going over your limit, call the bank before it calls you, clear or shrink the excess, and work out whether the limit itself is the problem. The order matters, because each step keeps more options open than the one after it.
- Call the bank first. Explain what caused the excess and when you expect it to clear. An early conversation usually keeps more options open than silence.
- Ask about a temporary excess. Some banks can approve a temporary excess, if the bank agrees, to cover a known gap such as a large customer payment due shortly. Terms and fees vary by bank.
- Clear or reduce the excess. Chase overdue invoices, move a non-urgent payment, or put in funds from elsewhere so the account is back inside its limit.
- Stop it happening again. List the scheduled payments due before your next deposit and reschedule what you can, so the account does not tip over on the same debit next month.
- Fix the structure. If the excess came from a limit that is too small for the business, look at a permanent increase through the overdraft limit guide, or a separate business line of credit or working capital loan to carry the swing.
The facility's annual review is a natural point to raise the limit; the annual review plan for an overdraft facility sets out how to prepare. If your bank will not move, a broker can look at options outside it, and you can check eligibility first. More guides for business owners sit in the Business Owners Hub.
Going over an arranged overdraft limit is a bank decision, not a right: the bank can decline the payment or honour it at its discretion, and an honoured excess usually costs extra interest or fees, which vary by bank.
Whether it is a breach depends on your facility letter, and repeated or unresolved excesses can lead to a review or a cut. Lenders read the pattern on your statements more than any single excess, so a quick call to the bank, a fast clearance and a properly sized facility protect both this facility and your next application.
Key takeaway: Watch available funds, not just the balance, and if excesses repeat, fix the limit rather than relying on the bank's discretion.Frequently Asked Questions
When you exceed your overdraft on a business account, the bank either declines the payment or lets it through at its discretion, usually charging extra interest or fees on the excess. The type and size of those charges varies by bank and is set out in your facility terms. Repeated or unresolved excesses can lead the bank to review the facility, and your credit limit can change as a result.
You can spend over your business overdraft limit only when the bank chooses to honour the payment, because spending past the limit is not a right that comes with the facility. Many banks decline payments past the limit automatically, and those that allow them usually charge for it. If you regularly need more room, size the limit to your real cashflow rather than relying on the bank's discretion each month.
For a business account, there is no set period your bank will let you stay over your overdraft limit, because it is at the bank's discretion and your facility letter decides. Most banks expect an excess to be cleared quickly and can treat one left unresolved as a default event. If you need extra room for a known period, ask the bank about a temporary excess before the payment goes out.
You are typically charged interest only on the drawn balance of a business overdraft, not on the unused part of the limit. Some facilities also carry a line or facility fee calculated on the full limit, which varies by lender and is set out in your facility terms. Our insight on whether a bank overdraft is an asset explains why the unused limit is not money the business has.
Going over your overdraft limit can affect future finance, because lenders see excesses and over-limit fees on your bank statements when they assess a new application. A one-off excess that cleared quickly usually matters less than a repeated pattern. How a facility reports to credit reporting bodies varies, so ask your lender how yours is reported.
