A retiree has been receiving a stable annual pension for three years. In 2026, a slight increase of a few hundred euros pushes their net global income above a tax threshold. As a result, they lose a special allowance that represented several thousand euros in deductions. This scenario, far from being rare, illustrates a concrete trap that can be anticipated by understanding the mechanics of the thresholds that condition the retirement tax allowance.
Threshold effect on the special allowance: when a small pension increase costs a lot
Article 157 bis of the General Tax Code provides for a special allowance for taxpayers over 65 or disabled, provided that their net global income does not exceed certain limits. There are two brackets: a full allowance for the lowest incomes, and a reduced allowance of half for those in an intermediate bracket.
The problem arises when one exceeds the upper limit, even by a few dozen euros. The special allowance disappears entirely, without any gradual reduction. It is not a proportional reduction: it is a cut-off.
Let’s take a concrete situation. A single retiree whose net global income is just below the intermediate threshold benefits from a reduced allowance. If an increase in their supplementary pension or a partial buyback of life insurance raises this income above the threshold, they lose the entire benefit. The final tax then increases much more than the additional income received.
What makes the situation tricky is that the 10% allowance on pensions continues to apply regardless of the net global income. Therefore, one can lose the special allowance while retaining the automatic deduction of 10%. To better understand the criteria for the retirement tax allowance, it is important to distinguish between these two provisions, which are governed by different rules.
10% allowance on retirement pensions: operation and limit
The 10% allowance is a distinct mechanism from the special allowance. It automatically applies to all declared retirement pensions, without age or income level conditions. The tax administration calculates it itself when processing the declaration.
This provision works like the 10% allowance that employees benefit from on their salaries. It is framed by an annual floor and ceiling:
- A guaranteed minimum amount, even for small pensions, set at a few hundred euros per household
- A ceiling that limits the deduction for retirees receiving high pensions
- An application per tax household, meaning that the ceiling applies to all pensions of the couple in the case of joint taxation
The retiree does not need to take any steps to benefit from it. However, there is an often-overlooked option: declaring actual expenses instead of the flat 10% allowance. This alternative can prove more advantageous in certain cases, especially for retirees who incur significant management fees on retirement savings products.
Retirement tax allowance for couples: doubling and joint taxation
For a married or civil partnership couple subject to joint taxation, the special allowance under article 157 bis can be doubled if both members of the couple meet the age or disability condition. This leads to a deduction that can represent a significant reduction in the taxable base.
Again, the income condition is assessed based on the net global income of the tax household, not on that of each spouse separately. A couple where both spouses are over 65 but whose global income exceeds the ceiling receives nothing, even if one of them has very low income.
- If only one spouse is over 65 and the household income remains below the threshold, only one allowance applies
- If both spouses meet the condition, the allowance is doubled subject to the same global income ceiling
- Disabled persons as defined by the provisions of article 195 of the CGI benefit from the same allowance, regardless of their age
The doubling of the allowance does not change the required income ceiling. Both members of the couple must meet the personal condition, but it is the global income of the household that determines eligibility.
Case of retirees in nursing homes
The accommodation costs in nursing homes do not reduce the net global income considered for the special allowance. There is often confusion between the tax reduction for dependency (which decreases the final tax) and a deduction from taxable income. These are two separate mechanisms. A retiree in a nursing home whose pension exceeds the ceiling of article 157 bis loses the special allowance, even if their actual expenses are high.
Income to monitor to retain the tax allowance for those over 65
The net global income includes all categories of income of the household: pensions, rental income, capital gains subject to the scale, investment income. A buyback on a life insurance contract can push the income above the threshold for a given year, even if this buyback is occasional.
Some situations deserve particular vigilance. The annual revaluation of Agirc-Arrco supplementary pensions, even modest, can be enough to exceed a ceiling. Similarly, renting out a property or receiving interest not subject to the flat tax can inflate the net global income.
Returns vary on this point, but many taxpayers discover the loss of the special allowance when they receive their tax notice, without having anticipated crossing the threshold. The only lever is to simulate the tax impact before carrying out an operation that increases income: buyback of life insurance, sale of shares, rental.
The 10% allowance on pensions, however, remains granted regardless of the income level. It constitutes a tax base that applies to all retirees without exception, as long as the declared incomes fall into the category of pensions and retirement. Keeping this distinction between the two allowances in mind helps avoid unpleasant surprises during the annual declaration.
