URSSAF Monthly or Quarterly Declaration: How to Choose in 2025
When creating your micro-enterprise, you are asked to choose your URSSAF declaration frequency: monthly or quarterly. This choice, often made hastily, affects your cash flow and admin workload throughout the year. Here is how to make it wisely.
The principle: declaring revenue to URSSAF
As a micro-entrepreneur, you declare your gross revenue collected to URSSAF at the chosen frequency. URSSAF automatically calculates your social contributions (fixed rate × declared revenue) and sends you a payment notice.
Mandatory rule: even if your revenue is zero, a declaration is required. Omitting any declaration — even a zero one — incurs penalties.
Monthly vs quarterly: practical differences
| Criterion | Monthly | Quarterly |
|---|---|---|
| Declaration frequency | 12 times/year | 4 times/year |
| Amount per payment | Small, regular | Large, quarterly |
| Declaration deadline | End of following month | 30 Apr / 31 Jul / 31 Oct / 31 Jan |
| Irregular income | Easier to manage | Less predictable |
| Admin burden | One declaration/month | One declaration/quarter |
Monthly example — €5,000 revenue in January, BNC 23.1%:
- Declaration due by 28/29 February
- Contributions due: 5,000 × 23.1% = €1,155 in February
Quarterly example — Q1 revenue of €15,000 (Jan–Mar), BNC 23.1%:
- Declaration due by 30 April
- Contributions due: 15,000 × 23.1% = €3,465 end of April
Quarterly declaration deadlines 2025
| Quarter | Period covered | Deadline |
|---|---|---|
| Q1 | January – March | 30 April |
| Q2 | April – June | 31 July |
| Q3 | July – September | 31 October |
| Q4 | October – December | 31 January (following year) |
Monthly declarations cover month M and must be filed before the end of month M+1. Example: January → before 28/29 February.
Why URSSAF recommends monthly declarations
Monthly frequency is recommended for three main reasons:
1. Cash flow smoothing
Contributions are spread across 12 payments rather than 4. You never face a payment 3–4 times your usual monthly amount. For irregular income — common when starting out — monthly frequency absorbs fluctuations better.
2. Early error detection
Declaring monthly lets you regularly verify that URSSAF applies the correct rate (especially with ACRE or an activity type change).
3. Healthy financial habits
A monthly-declaring auto-entrepreneur develops useful financial discipline: real-time revenue tracking and no unpleasant contribution surprises.
How to change your declaration frequency
At creation: you choose your frequency when registering. To opt for quarterly, you must exercise this option within the month following your business creation.
During activity: to change frequency, you must apply before 31 October for a change effective 1 January of the following year. The request is made in your account at autoentrepreneur.urssaf.fr under "Gérer mon contrat".
Frequency cannot be changed mid-year.
Penalties for late declarations
URSSAF applies automatic penalties for late or missed declarations:
- Late surcharge: 1.5% of contributions due per month of delay
- Fixed penalty: 5.5% of estimated contributions in the absence of a declaration (URSSAF reconstructs the revenue)
The penalty is significant for high revenues. If you have missed a declaration, regularise immediately at autoentrepreneur.urssaf.fr — the platform allows filing for past periods.
Does ACRE affect declaration frequency?
No. Your declaration frequency is independent of ACRE. If you benefit from ACRE, the reduced rates are applied automatically by URSSAF upon validation of your application, regardless of your chosen frequency. Check your first contribution notice to confirm the ACRE rate is correctly applied.
