EDF Due Date Calculator: Never Miss a Filing

An EDF due date calculator takes an invoice date and tells you two things: the last day to file the Export Declaration Form for it, and the date by which the invoice must be paid. The filing rule is 30 days from the end of the month in which the invoice was raised, so every invoice in a month shares one EDF deadline, while each invoice gets its own realisation deadline 9 months from its date. Our free calculator does both instantly, but it helps to understand the arithmetic behind it.

Key takeaways

• EDF deadline = end of the invoice month + 30 days (Regulation 3(2) of the 2026 export regulations).
• Most months produce a deadline on the 30th of the following month; January invoices are the exception, landing in early March.
• Realisation deadline = 9 months from each invoice date for foreign-currency invoices, 12 months for rupee invoices.
• Services other than software also have an alternative: the EDF may be filed on or before the date payment is received.
• A calculator removes guesswork at month end, when most errors happen.

How the calculator works

You enter an invoice date (or just the month). The calculator:

1. finds the last day of that month;
2. adds 30 days to give the EDF due date;
3. adds 9 months to the invoice date for the realisation deadline (or 12 months if you mark the invoice as in Indian rupees).

That is all. The value is in doing it reliably for every invoice, every month, without someone counting days on a wall calendar. Try it on our EDF due date calculator.

The rule in practice: worked dates

Here are the due dates for the first year of the new regime, taken from the rule as applied to each month.

Notice the pattern: in most months the deadline falls on the 30th of the next month. January breaks it because February is short. Thirty days from 31 January 2027 runs through all 28 days of February and lands on 2 March 2027. In a leap year, when February has 29 days, the same count lands a day earlier. The calculator handles this so you do not have to remember it. The full table is on our EDF due dates page.

Realisation dates: one per invoice

The EDF deadline groups invoices by month. The realisation deadline does not; it follows each invoice.

Example. Tidewater Data Labs Pvt Ltd, a Thiruvananthapuram company, raised four invoices in January 2027:

All four share one EDF due on 2 March 2027. Their payment deadlines differ, and the rupee invoice gets 12 months instead of 9. Tidewater's accountant copies these dates into the company's EDF register as soon as the invoices are raised.

The "on or before payment" alternative

For services other than software, the Regulations also allow the EDF to be submitted on or before the date payment is received. If a client pays a January invoice on 10 February, an EDF filed by 10 February also satisfies the rule.

Most exporters ignore this and use the monthly deadline, because one predictable date beats tracking payment dates. The calculator shows the standard monthly deadline; if you rely on the payment-date alternative, track it separately. If your bank holds an incoming payment until it has an EDF, filing promptly is the quickest fix whichever deadline applies.

Where people go wrong without a calculator

• Using the work period instead of the invoice date. A 2 November invoice for October work belongs to November, due 30 December, not 30 November.
• Assuming "30th of next month" always. January is the exception, and leap years shift it.
• Treating the EDF date as the payment deadline. Filing on time does not stop the realisation clock, which runs from each invoice date.
• Forgetting late-dated invoices. An invoice dated 31 October is still an October invoice, due 30 November.
• Missing the extension window. If a payment will be late, ask your AD bank for an extension before the 9 months end.

A bank may accept a delayed EDF for reasonable cause, but that is a fallback, not a plan. This is general information, not legal or tax advice.

Building it into your month

1. On the 1st of each month, list last month's export invoices.
2. Run the dates through the calculator and note the EDF deadline and each realisation date.
3. Set a reminder a week before the EDF deadline.
4. Prepare the EDF with our EDF form generator, submit it and log the date.
5. Each month, check your register for invoices approaching their realisation deadline.

Frequently asked questions

How is the EDF due date calculated?

Take the last day of the month in which the invoice was raised and add 30 days. For most months that gives the 30th of the following month; January invoices fall due in early March because February is short.

Why is the January 2027 EDF due on 2 March and not 28 February?

Thirty days counted from 31 January 2027 run through the 28 days of February 2027 and end on 2 March 2027. The rule counts days, not calendar months.

Does the calculator also give the payment deadline?

Yes. It adds 9 months to each invoice date for foreign-currency invoices, or 12 months for invoices in Indian rupees, to show when full realisation is due.

If I file the EDF early, does that change my realisation deadline?

No. The realisation deadline runs from the invoice date regardless of when you file the EDF. Filing early is good practice but does not extend or shorten the payment window.

Bottom line

The EDF deadline is simple arithmetic with one awkward month, and the realisation deadline is per invoice. Let a tool do both every month. Enter your invoice dates into our free EDF due date calculator and put the results straight into your register.
