A client owes you Rs. 2,00,000. The invoice was due 45 days ago. They are not responding to your emails. Can you charge interest? The answer is yes — and this guide covers the legal basis, enforceable rates, exactly how to word your invoice clause, and the GST implications of late payment interest in India.
Can You Legally Charge Interest?
Yes. Indian law supports charging interest on late payments, provided certain conditions are met:
- There must be a prior agreement. The most enforceable interest is one that was agreed to before the work began — either in your service agreement/contract or in your invoice payment terms. Without prior agreement, you can still claim interest under general contract law, but enforcement becomes harder.
- The rate must be reasonable. Courts in India generally uphold interest rates up to 18-24% per annum for commercial transactions. Rates above 36% per annum may be deemed usurious and struck down.
- The payment must be overdue. Interest accrues only after the agreed payment date has passed. If your invoice says "Payment due within 15 days" and the client pays on day 16, interest starts from day 16.
Legal Basis in India
Several laws provide the foundation for charging late payment interest:
| Law | Provision | Application |
|---|---|---|
| Indian Contract Act, 1872 | Sections 73 and 74 — liquidated damages and penalties | Most freelancer-client relationships fall under this. You can claim reasonable damages (including interest) for breach of contract (late payment). |
| MSMED Act, 2006 | Section 16 — interest on delayed payments | If you are registered as a Micro or Small Enterprise under Udyam, the buyer must pay compound interest (monthly rests) at three times the RBI Bank Rate on delayed payments — 17.25% a year at the 5.75% Bank Rate in force from 7 October 2026. Payment is due on the agreed date, and the Act does not allow that date to be more than 45 days out. |
| Interest Act, 1978 | Court-awarded interest on debts | If you take the matter to court, the court can award interest at a rate it deems reasonable (typically 6-18% per annum). |
Interest Rate Limits
There is no single statutory interest rate for commercial late payments. Here are the practical ranges:
| Scenario | Rate Range | Notes |
|---|---|---|
| Contractual (agreed in invoice/contract) | 12-24% per annum | Most enforceable. 18% is the most common rate in Indian commercial contracts. |
| MSMED Act (registered micro/small enterprise) | 3x Bank Rate (17.25% at today's 5.75%) | Compounded monthly. The rate moves with the RBI Bank Rate (5.75% from 7 October 2026, so 3x = 17.25%) — recheck the current Bank Rate when you calculate. |
| Court-awarded | 6-18% per annum | Depends on the court's discretion and the facts of the case. |
| No prior agreement | 6-12% per annum | Harder to enforce. Courts may apply a "reasonable" rate. |
Practical recommendation: Set your standard interest rate at 1.5% per month (18% per annum). This is the most commonly used rate in Indian commercial invoicing. It is enforceable, reasonable, and understood by corporate finance teams.
The best late payment clause is one you never have to enforce. Its real value is deterrence — clients who see a clear interest clause on every invoice tend to pay on time because they know the cost of not paying.
How to Word Your Invoice Clause
Here are two ready-to-use invoice payment terms clauses. Pick the one that fits your tone:
The formal clause is stronger legally but may feel aggressive for smaller clients. The friendly clause is more relational but provides weaker legal recourse. For corporate clients, use the formal clause. For individual clients or long-term relationships, the friendly approach often works better.
Practical Tips
- Include the clause on every invoice, not just overdue ones. The interest term should be a standard part of your invoice template. Adding it only after a payment is late looks retaliatory and is harder to enforce.
- Send a reminder before applying interest. On the due date, send a polite reminder. After 7 days overdue, send a second reminder mentioning the interest clause. After 15 days, send a formal notice with the interest amount calculated. This paper trail strengthens enforcement.
- Calculate interest clearly on the reminder. "Your invoice of Rs. 2,00,000 dated 01-Mar-2026 was due on 16-Mar-2026. As of 01-Apr-2026 (16 days overdue), late payment interest of Rs. 1,578 (18% per annum, pro-rated daily) has accrued. Total outstanding: Rs. 2,01,578."
- Be willing to waive for good clients. Interest clauses are leverage, not punishment. If a long-term client pays 5 days late once, waiving the interest maintains the relationship. If a client is chronically late, enforce it or require upfront payment.
- Consider a deposit for new clients. For first-time clients or large projects, request a 25-50% advance. This reduces your exposure to non-payment and signals professionalism.
GST on Late Payment Interest
This is a frequently misunderstood area, but the rule itself is clear:
- If you are GST-registered, late payment interest you receive is part of the value of your original supply (CGST Act s.15(2)(d)). It attracts GST at the same rate as that supply — 18% for most professional services — whether or not the interest was agreed in advance. CBIC Circular 178/10/2022-GST (para 9) says this directly. When the interest is received, raise a tax invoice or debit note for it with GST.
- If you are not GST-registered, there is no GST to add.
FAQ
Can I charge interest without a written contract?
Yes, but enforcement is weaker. Under the Indian Contract Act, you can claim damages for breach (late payment), but the court will determine a "reasonable" rate rather than your preferred rate. Having a written interest clause in your invoice terms or contract makes enforcement significantly easier. Even an email acknowledgment of payment terms helps.
What is a reasonable interest rate for freelancer invoices?
The most common rate in Indian commercial invoicing is 1.5% per month (18% per annum). This rate is widely accepted by courts and corporate clients. Rates above 24% per annum may be questioned. The MSMED Act rate of 3x the RBI Bank Rate works out to 17.25% at the 5.75% Bank Rate in force from 7 October 2026.
Should I register under Udyam as a freelancer?
If you have corporate clients who frequently pay late, Udyam registration gives you stronger legal protection under the MSMED Act (an agreed payment period of no more than 45 days, compound interest at 3x the RBI Bank Rate). Registration is free at udyamregistration.gov.in and requires only your Aadhaar and PAN. In that situation it is usually worth doing.
Can I stop work if a client has not paid a previous invoice?
Yes, if your contract allows it (most standard freelancer agreements include a clause for stopping work on payment default). Even without a specific clause, you have the right under Indian contract law to suspend performance if the other party has breached a material term (payment). Communicate this in writing before stopping work.
Is there a legal limit on how much interest I can charge?
There is no statutory cap for commercial transactions (unlike consumer lending, which is regulated). However, Indian courts may reduce interest rates they deem "unconscionable" — typically anything above 36% per annum. Stick to 18-24% per annum to be safe. Under the MSMED Act, the rate is fixed at 3x the RBI Bank Rate (17.25% at the 5.75% Bank Rate in force from 7 October 2026).
