A declared home employee via the CESU, a home check received from the works council, and a checkbox on the income tax declaration: these three elements form a tax circuit that many private employers only partially exploit. The tax credit related to personal services reaches half of the expenses incurred (net salaries and social contributions), but one must know which expenses are included in the calculation and which limits apply.
Coordinating declarative CESU and pre-financed CESU without losing money requires mastering a few precise rules.

Pre-financed CESU and home check: what changes in the calculation of the tax credit
People often confuse declarative CESU and pre-financed CESU, while their tax impact differs on a specific point. The declarative CESU is used to declare a home employee to URSSAF. The pre-financed CESU (of which the home check is a well-known brand) is a payment title co-financed by the employer, the CSE, or a public organization.
When receiving pre-financed CESUs, only the remaining charge qualifies for the tax credit. The portion financed by the company or the CSE must be deducted from the declared amount. An individual who pays their housekeeper with home checks, half of which is covered by their employer, can only declare the remaining half. Ignoring this rule exposes one to a reassessment during a tax audit.

To learn everything about CESU benefits and check the deductible portion according to your situation, you need to cross-reference the CESU tax certificate with the co-financing documents provided by your employer or your CSE.
CESU tax certificate: the document that conditions everything else
The tax certificate is the pivot of optimization. Without it, there is no tax credit. Since March 2026, URSSAF makes it available at the beginning of the declaration campaign, in the “My tax advantage” section of the CESU dashboard.
This document summarizes the net salaries paid and the social contributions deducted over the year. It also includes salary supplements (bonuses, mileage allowances, transportation costs). However, severance pay does not qualify for the tax credit and should not be added to the certified amount.
Check the amounts before declaring
There is a tendency to report the figure from the certificate as is. This is a mistake when combining declarative CESU and pre-financed CESU. The amount of the URSSAF certificate covers all sums paid, but the portion co-financed by a third party must be subtracted. Keeping the CESU payslips and home check statements side by side allows for recalculating the actual amount to declare.
Limits by type of personal service: thresholds that no one monitors
The tax credit is capped overall, but some services have their own limits, often lower than the general cap. Forgetting these means declaring amounts that will be rejected by the tax administration anyway.
- Minor DIY (interventions of a maximum of two hours) is capped at 500 euros per tax household per year.
- Home IT and internet assistance cannot exceed 3,000 euros of eligible expenses per year.
- Minor gardening work is limited to 5,000 euros per tax household per year.
Beyond these thresholds, expenses do not generate any additional tax benefit. If one employs a gardener and a handyman simultaneously, each cap applies independently. Grouping these services under a single line “personal services” in one’s mind risks overestimating the expected tax credit.
Adjusting spending strategy
When approaching a specific cap, it is better to plan interventions over two fiscal years rather than concentrating everything. A gardening project spread between December and January allows for distributing expenses over two periods and maximizing the tax credit for each.
Immediate advance of the CESU tax credit: reducing cash flow lag
The classic tax credit involves advancing the total amounts and then waiting for reimbursement during the income tax declaration, sometimes more than a year after the expense. The immediate advance CESU system changes this logic.
With the immediate advance, the tax credit is deducted in real-time from the amount collected. One only pays half of the actual cost each month, with URSSAF directly paying the portion corresponding to the tax credit to the employee. Activation is done from the CESU dashboard, in the “My aids” section.
This mechanism does not change the total amount of the tax advantage. It eliminates the cash flow lag, which changes the game for households hesitant to employ someone at home due to lack of immediate budget. Feedback varies on the fluidity of the system depending on the departments, but the principle remains the same everywhere.
Cumulative immediate advance and pre-financed CESU
The two systems do not exclude each other, but their coordination requires rigor. Home checks cover part of the salary, while the immediate advance reduces the remaining charge of the uncovered portion. The risk: double counting an advantage. The rule to remember is that the total of the aids can never exceed the actual cost of the service.
- First, calculate the portion covered by the pre-financed CESUs received from the employer or the CSE.
- Apply the immediate advance only to the remaining balance at your charge.
- Keep the URSSAF statements and the home check slips used each month.
A household that combines both without precise tracking discovers the problem at the time of declaration when the tax certificate shows an amount inconsistent with the actual deductions. Archiving the supporting documents month by month, rather than at the end of the year, avoids this situation.
