Late Payment Interest Laws by Country: What Freelancers Can Legally Charge on Overdue Invoices

India's MSMED Act rate is the highest here at 17.25%, and it compounds monthly. The US figure of 4.75% only covers federal agencies paying vendors, so it says nothing about what a private US client owes you.

Every EU country on the list sits at 10.00% or above for July to December 2026, with Romania top at 14.50%. Even the lowest rate on the list is 10.00% a year on a late business invoice.

The federal rate fell as low as 0.875% in early 2021 and has stayed between 4.125% and 4.875% since January 2023. It moves every six months, so check the current figure before quoting it.

The fixed charge is per invoice, not per client. On small invoices it can be worth more than the interest itself.

Thirty days is the common default when no date is agreed. India is stricter: without a written agreement, a payment to a micro or small enterprise is late 15 days after acceptance.

How much interest can I charge on a late invoice?

That depends on where your client is based and what your contract says. If neither the contract nor a statute gives you a rate, interest usually comes down to what a court will award, and that's slow.

In the UK, the Late Payment of Commercial Debts (Interest) Act gives you 8% plus the Bank of England base rate on business-to-business debts. With Bank Rate at 3.75%, that's 11.75% a year. You also get a fixed sum of £40, £70 or £100 per invoice depending on its size, plus reasonable extra recovery costs.

Across the EU, the Late Payment Directive works the same way through national law. Rates for July to December 2026 run from 10.00% in Denmark and Sweden to 14.50% in Romania. Germany sits at 10.52% and France at 12.40%. You can also claim EUR 40 for each invoice paid late, and some countries set a higher amount for bigger invoices.

India is the outlier. Under the MSMED Act, a buyer who pays a registered micro or small enterprise late owes 3x the RBI Bank Rate, compounded monthly. With the Bank Rate at 5.75%, that's 17.25% a year before compounding.

Is there a late payment interest law for US freelancers?

Not at the federal level for private clients. The Prompt Payment Act sets a rate, 4.75% for July to December 2026, but it only applies when a federal agency pays a vendor late. If your client is a startup in Austin or an agency in Chicago, that rate doesn't reach them.

New York is the main exception. The state's Freelance Isn't Free Act doesn't set an interest rate. Instead, a client who breaks the payment rule can owe you double damages, meaning double the unpaid amount. The rule covers contracts of $800 or more, counted alone or combined with the same client over 120 days. If your contract has no payment date, the client must pay within 30 days of the work being completed. New York City has its own version with the same double-damages remedy.

Everywhere else in the US, your contract does the heavy lifting. A clear late fee or interest clause is what turns an overdue invoice into a claim with a number attached. Some states limit how much interest or late fees a contract can charge, so keep your rate reasonable and check your state's rules before you pick one.

A good US clause names the rate, says when it starts (for example, the day after the due date), and adds that the client pays your collection costs. Put the same terms on your invoices. A rate the client signed is far easier to enforce than one you add to an invoice after the fact.

What happens if my contract sets a different rate?

In the UK, a rate written into the contract replaces statutory interest. That cuts both ways. A client's template that says late invoices carry no interest, or a token rate, can quietly take away a right you'd otherwise have. The law does let courts set aside a term that isn't a substantial remedy, but you don't want to argue that over one invoice.

In the EU, the contract usually sets the payment term, and the 30-day default only kicks in when it's silent. Watch for long terms pushed by bigger clients. A long term doesn't break any rule on its face, but it pushes back the date interest starts. The directive also limits how far terms can stretch, and grossly unfair ones can be challenged, but that's a fight you'd rather avoid by negotiating the term up front.

In India, the contract can't stretch things past 45 days after acceptance for a micro or small enterprise. A clause promising payment months later doesn't override the Act. Interest still runs from the legal deadline.

Which country's law applies when your client is abroad?

Generally, the governing law clause decides. If you're a UK freelancer and your contract says it's governed by the law of England and Wales, you can rely on the UK Act even with a client overseas. If the client's template picks their own state or country, their rules apply, and those may give you nothing.

A few other limits matter. These laws cover business-to-business invoices. The EU's EUR 40 compensation, for example, can't be claimed against consumers. And India's protection only helps if you're a registered micro or small enterprise, which makes Udyam registration worth doing before you invoice a large buyer. If you can't get your own governing law, at least make sure the contract has its own interest clause, so you're covered whichever law ends up applying.

Is it worth charging interest on a late invoice?

Often the interest itself is small. The GOV.UK worked example shows a £1,000 debt earning about 23p a day, or £11.50 after 50 days, at an older and much lower base rate. The fixed charge of £40 or EUR 40 usually matters more than the interest on a small invoice.

The real value is the pressure it adds at the right moment. A polite reminder that names the statute and the amount tends to move your invoice to the top of the pile. Indian micro and small enterprises have filed 2,56,892 delayed-payment applications on MSME Samadhaan, which tells you plenty of people do use these rules when a buyer stops answering.

• Put the interest rate, the fixed charge and the due date on every invoice, not just in the contract.
• Send a reminder the day after the due date, and quote the exact amount owed with interest.
• Keep records of acceptance or delivery dates, since that's when the clock starts in India and under the UK default.
• Decide in advance when you'll waive interest for a good client, so it's a choice and not a habit.
• If a client is weeks late with no reply, send a formal demand that cites the law before going further.
