Most Irish business owners know the frustration of chasing an overdue invoice. What far fewer know is that they are legally entitled to charge interest on late payments in Ireland — automatically, without going to court, and without needing a specific clause in their contract.
This is one of the most underused rights available to Irish SMEs, and it can make a real difference both to your cash flow and to how seriously your payment terms are taken.

The Law Behind being able to Charge Interest on Late Payments in Ireland?1
Under EU law — specifically the EU Directive on Combating Late Payments, implemented in Ireland through the European Communities (Late Payment in Commercial Transactions) Regulations — businesses are entitled to claim statutory interest on any overdue commercial invoice. This applies to transactions between businesses, and to payments owed by public authorities.
It does not apply to transactions with consumers — this is a business-to-business and business-to-government entitlement only for Debt Collection Services.

What Rate of Interest Can You Charge?
If your contract does not specify an interest rate, the statutory rate applies automatically. For Ireland, the current statutory interest rate for late payment is 10.15% per annum (applicable from 1 January 2026 to 30 June 2026).
This rate is set twice yearly by the European Central Bank and adjusted accordingly. You do not need to do anything special to be entitled to it — it applies by law once a payment becomes overdue.
If your contract does specify a rate, you can charge that rate instead, provided it is not grossly unfair to the debtor.

When Does Interest Start Running?
Interest becomes due from the day after the payment deadline passes. Here is how that works in practice:
– If you have agreed payment terms (for example, 30 days net): interest runs from day 31.
– If you have not specified a payment period: interest becomes payable automatically 30 calendar days after your customer receives your invoice or payment request.
– If you are unsure when the invoice was received: you can claim interest 30 days after you delivered your goods or completed your services.
One important point — if you issue an invoice before completing the work or delivering the goods, the 30-day clock does not start until delivery is complete.

The €40 Compensation Fee
In addition to interest, you are entitled to claim a flat rate compensation fee of €40 per invoice that is paid late. This is automatic — it does not need to be in your contract and you do not need to go to court to claim it.
If your actual costs in recovering the debt — such as administrative time, debt collection agency fees, or legal costs — exceed €40, you can claim reasonable additional compensation on top of that.
Interest is charged on the gross amount of the invoice including VAT, though you do not pay VAT on the interest itself.

A Practical Example
Say a customer owes you €5,000 and is 90 days late paying. Here is roughly what you are entitled to claim on top of the original debt:
– Interest: €5,000 × 10.15% ÷ 365 × 90 days = approximately €125.34
– Flat rate compensation: €40.00
– Recovery costs (if referred to a debt collection agency): recoverable on top of the above if included in your terms and conditions.
The total additional claim would be approximately €165+ before recovery costs — not insignificant, and a meaningful incentive for customers to pay on time.

Why Most Businesses Don’t Claim It
In our experience at Taylor Ryan Recoveries, the vast majority of Irish businesses are simply unaware that this entitlement exists. Others know about it in theory but worry that raising interest will damage the customer relationship.
This is understandable, but worth examining. A customer who is consistently paying late is already straining the relationship — and the cost of that unpaid cash sitting in your debtors ledger is very real. Applying statutory interest is not aggressive; it is the lawful exercise of a right that exists precisely to discourage late payment culture and protect the cash flow of smaller businesses.
The practical approach we recommend is to include a clause in your Terms and Conditions stating that statutory interest will be applied to overdue invoices. This does two things: it puts the customer on notice from the outset, and it strengthens your position if recovery is ever needed.

How to Recover Your Debt
If a payment remains outstanding, your options in Ireland include:
1. Reissue the invoice with interest and the €40 compensation fee added
2. Refer the matter to a debt collection agency — fees are recoverable as part of your claim
3. Issue proceedings through the District or Circuit Court depending on the amount
4. Use the European Order for Payment procedure for cross-border debts within the EU
At Taylor Ryan Recoveries, we work on a no-win, no-fee basis, meaning there is no upfront cost to you for referring a debt for collection. Recovery costs are added to the debtor’s balance in accordance with the legislation.

The Bottom Line
Irish businesses are leaving money on the table by not exercising their statutory right to interest and compensation on late payments. The rules are clear, the entitlement is automatic, and the rate — currently 10.15% — is not trivial on any meaningful invoice value.
If your business regularly carries overdue invoices, it is worth reviewing how you communicate payment terms, whether your T&Cs reference statutory interest, and whether referring persistent late payers for recovery might be more cost-effective than you think.
