URSSAF Declaration for Auto-Entrepreneurs: 2026 Calendar and Steps

A declaration you can't afford to skip, even at zero

Léa started her graphic design business as an auto-entrepreneur back in March. Three months in, an email from URSSAF reminded her of a deadline she'd completely forgotten about. She hadn't even invoiced anything that month. This happens to thousands of French freelancers every year, usually because one simple rule gets overlooked.

The URSSAF declaration for auto-entrepreneurs means reporting your turnover every month or every quarter on autoentrepreneur.urssaf.fr, even when it's zero. It's the basis for calculating social contributions and it determines your access to social protection as a self-employed worker in France.

Who has to declare, and how often?

Every registered auto-entrepreneur must declare turnover actually received, whether or not any work happened during the period. The frequency (monthly or quarterly) is chosen when you register and can be changed once a year, before October 31, to take effect the following year.

Monthly reporting suits steady activity: it smooths out cash flow and avoids surprises. Quarterly reporting appeals more to seasonal work or a slow start, where revenue swings a lot from one month to the next. Neither option is objectively better. It depends on your billing rhythm and how comfortable you are with admin.

One question comes up constantly: do you still need to declare with no sales at all? Yes. A zero declaration is still mandatory. Skipping it triggers the exact same penalties as skipping a declaration with positive revenue.

And if your turnover is creeping toward the micro-entreprise limits, it's worth checking our piece on the 2026 micro-entreprise threshold too.

The 2026 URSSAF declaration calendar

In 2026, the monthly declaration is due by the last day of each month for the previous month's revenue. The quarterly declaration follows four fixed deadlines: April 30, July 31, October 31, and January 31, 2027, for the last quarter of 2026.

Option chosen	Period covered	Deadline
Monthly	Each month M	Last day of month M+1
Quarterly	January to March 2026	April 30, 2026
Quarterly	April to June 2026	July 31, 2026
Quarterly	July to September 2026	October 31, 2026
Quarterly	October to December 2026	January 31, 2027

Here's a tip experienced freelancers swear by: set a recurring reminder the day you register. URSSAF does send email notifications, but they get lost in spam folders or buried in a busy week more often than you'd expect.

How to declare your turnover, step by step

The whole process rarely takes more than five minutes once you know the route. Here's exactly what to do.

1. Log in to autoentrepreneur.urssaf.fr with your social security number.
2. Select the period you're declaring from the dashboard (the month or quarter just ended).
3. Enter the turnover you actually received during that period, not what you invoiced.
4. Check the contribution amount the system calculates automatically based on your activity type (sales, services, or a liberal profession).
5. Confirm the declaration, then pay online by direct debit or card.
6. Save the confirmation receipt. You'll want it if there's ever a review or a dispute.

A common mistake: mixing up turnover received with turnover invoiced. URSSAF calculates your contributions on what actually landed in your bank account, not what you billed. An invoice sent in December but paid in January gets declared in January, not December.

Missing or late: what it actually costs

A missing declaration costs a flat penalty of 60.10 euros in 2026. If it's still unresolved by December 31 of the following year, a surcharge of 5% to 15% of estimated turnover gets added on top. A late declaration filed after a formal notice triggers a separate penalty equal to 3% of the contributions owed.

These numbers often catch people off guard, because they apply even to a zero declaration. The administration doesn't distinguish between an honest slip and repeated neglect: the penalty clock starts the day after the deadline passes. If you do miss one, the right move is to fix it immediately rather than wait for a reminder letter, which only makes the bill bigger. The exact contribution rate you owe also depends on current rates, updated under the 2026 social contribution reform for France's self-employed.

According to a URSSAF study published in January 2026, only 49.8% of administratively active micro-entrepreneurs report turnover that's actually positive over the period observed. In other words, close to half of all registered auto-entrepreneurs show no measurable economic activity at all, which makes the zero declaration far more common, and far more often forgotten, than people assume.

Not sure what your upcoming contributions will look like? The official autoentrepreneur.urssaf.fr platform has a built-in simulator. For broader questions about your rights as a self-employed worker, service-public.fr is a reliable, up-to-date reference.

Wage portage: the alternative that removes this declaration entirely

Not every independent professional wants to manage this reporting cycle themselves, especially once activity grows past the micro-entreprise ceilings. Wage portage lets you work independently without ever touching autoentrepreneur.urssaf.fr.

In practice, the whole logic shifts:

• You find your own clients and negotiate your assignments, just like any independent worker.
• The umbrella company invoices your work on your behalf.
• It collects and pays your social contributions directly to URSSAF, exactly as any employer would.
• You receive a net salary every month, complete with a payslip and employee status.

What really changes is where the risk sits. No more 60.10 euro penalties for a declaration forgotten on a Sunday night: the umbrella company carries that administrative responsibility, in exchange for a commission on invoiced revenue. To see what that would actually look like for your own numbers, Weepo's wage portage salary simulator calculates your net pay in a few clicks, based on your day rate or projected turnover.

At Weepo, this question comes up constantly in first conversations with freelancers who are tired of the paperwork. There's no single right answer. It depends on how much work you're taking on, how much you need predictable income, and how much patience you have for online admin in the first place.

Frequently asked questions

When do I need to declare URSSAF as an auto-entrepreneur?

Depending on the option chosen when you registered, you declare either every month before the last day of the following month, or every quarter on one of four fixed dates (April 30, July 31, October 31, or January 31 of the following year).

What are the URSSAF declaration deadlines in 2026?

For the quarterly regime in 2026, the dates are April 30, July 31, October 31, then January 31, 2027, for the final quarter of the year. The monthly regime rolls on a fixed schedule, the last day of each month.

What happens if I declare zero turnover?

Nothing unusual: a zero declaration is valid and mandatory whenever no sales were received during the period. It triggers no contributions, but skipping it entirely exposes you to the same penalties as any other missed declaration.

How do I correct a mistake after submitting my declaration?

A correction can usually be made directly from your autoentrepreneur.urssaf.fr account, in the declaration history. Past a certain point, you'll need to contact your regional URSSAF office to sort it out.

Does wage portage really remove all URSSAF declarations?

Yes, on the social contributions side. The umbrella company becomes your legal employer and handles the declarations and payments to URSSAF itself, in place of the ported consultant.
