2026 tax refund: dates and calculation

Update March 2026 - In 2026, the personal tax refund still follows a two-step logic for many households: 60% advance in January on certain recurring tax benefits, then regularization in the summer of 2026 after processing the 2025 income declaration. Added to this is the possible reimbursement of an overpayment linked to withholding tax. The subject is therefore at the same time calendar, declaration and banking.

Short answer: if you are entitled to a refund, the administration will in principle automatically pay it into the account known to the tax authorities. In 2026, it is especially necessary to distinguish between the January advance, the balance paid in the summer and the possible overpayment linked to withholding tax. The RIB and the declaration remain the two points to check as a priority.

January 2026

For certain taxpayers, an advance of 60% could be paid in January 2026 based on the tax reductions and credits previously declared.

This advance is not a final reimbursement. It is an estimate calculated from the recurring tax advantages that the administration already knows. It aims to avoid waiting until summer to receive the majority of the tax gain. In practice, this is useful, but it also creates frequent confusion: many households think that the amount received in January corresponds to the total amount that will be owed to them.

Summer 2026

Regularization then occurs after the 2025 income declaration and the final calculation of the 2026 tax. This is when an additional refund can be paid if you are entitled to more than the advance received or if you have paid too much via withholding tax.

The tax site points out that reimbursements are in practice paid automatically, generally by transfer, if the administration knows your bank details. The exact date appears on the tax notice.

Clearly, the good reflex is not to wait for a transfer without further verification. You must read the tax notice, look at the amount returned, identify the origin of the payment and compare with the amounts already received in January. It is only at this moment that we know whether the reimbursement is a real supplement or a simple technical regularization.

In practice, three milestones really matter:

• January 2026 for the 60% advance on certain credits and tax reductions;
• summer 2026 for reimbursement or the balance after processing the declaration;
• September 2026 for a possible recovery if the advance was too high. These guidelines are useful, but they never replace reading the tax notice. This is the reference document to know if the payment is a reimbursement, a regularization or a recovery of advance.

The amount depends in particular:

• the final amount of your tax
• samples already taken
• tax credits and reductions taken into account
• the advance possibly paid in January

The calculation is therefore a progressive subtraction. We start from the theoretical tax, we withdraw the withholding tax already collected during the year, then we add or remove the tax credits and reductions. If an advance was paid in January, it still modifies the final result.

The three most common cases

• you paid too much during the year: the administration reimburses you for an overpayment;
• you are entitled to recurring tax credits or reductions: a deposit was paid in January then regularized in the summer;
• you have incorrectly calibrated your eligible expenses: an advance that is too high can be taken back in September.

The good reflex consists of distinguishing:

• the overpayment linked to withholding tax
• regularization of tax advantages
• net reimbursement after taking into account the advance

In our practice, it is often this distinction that avoids misunderstandings. The same transfer can correct an excess withholding, settle a tax credit or take back an overly generous advance. So not everything is read in the same way.

For a more general view, also consult tax refund: how does it work?, income tax optimization and our article tax or social question if your file combines several subjects.

• is your RIB in the tax area up to date?
• did you modify or cancel the advance on time when necessary?
• have you benefited for the first time from a tax credit for 2025?

Add to this a simple but essential check: is your postal address correct in your particular space? If the transfer is impossible or if the file requires a check letter, an obsolete address may delay the payment.

A useful reflex before summer

Before summer regularization, reread your last declaration with a "cash flow" perspective. Note the expected tax benefits, amounts already received, and credits you may have reduced. This mini-review avoids the surprises of September.

• believe that the January advance corresponds to the final reimbursement
• forget that an advance can be taken back
• wait for a refund on an old account
• do not check the tax notice

We also often see a more subtle error: confusing "regularization" and "gain". In reality, a refund can simply correct an advance that is too high or a withdrawal that is too large. The real subject is therefore the consistency between the past year and the final reading of the tax.

Hayot Expertise Advice: in 2026, never think about the January transfer alone. The real amount can be read after the summer regularization and the tax notice.

Let's take a household which received an advance in January 2026 for home employment and donations. If its 2025 expenses are ultimately a little lower than the previous year, the advance may have been too high. Conversely, if expenses have increased or if a new credit has appeared, summer regularization may be more favorable.

The key point is simple: the amount received is not always the amount earned. It can be a deposit, a supplement, or the correction of an excess payment.

If the date indicated on the notice has passed and the transfer does not appear, you must first check the RIB and the declaration situation. Then, if everything is correct, it becomes relevant to contact your manager service via the secure messaging of the particular space.

In more complex files, particularly when several households, several bank accounts or several tax years are at stake, an accountant's view often allows the origin of the blockage to be quickly identified.
