Income Tax - Retirement Savings Contributions (deduction)

Verified 01 January 2024 - Legal and Administrative Information Directorate (Prime Minister)

Do you have a retirement savings product? In some cases, you can deduct the contributions paid from your overall net income. To qualify, you must indicate the amount of contributions paid on your income tax return. We tell you the rules to know.

Retirement savings products are savings products long-term.

During the investment phase, you can, in some cases, deduct the contributions you make.

You will have to wait for your retirement (except exceptional release case) to touch a life annuity or a capital.

That money will then be taxable.

You may be eligible for the deduction of contributions you have made for the following retirement savings products, subject to conditions:


certain contributions paid as a result of self-employment are only deductible from business income concerned (industrial and commercial benefits - BIC or non-commercial profits - BNC for example).

The deductible contributions are the ones you pay voluntarily on an individual basis.


contributions paid to buy back retiring quarters are deductible under special conditions.

Amounts paid in a year shall be deductible from the taxable income of the year in question, up to a maximum fixed for each member of the tax shelter.

For example, amounts paid in 2023 are deductible from your 2023 taxable income (2024 reporting).

The amounts paid in 2024 will be deductible from your 2024 taxable income (2025 reporting).


the ceiling available for contributions paid in 2024 is indicated on your tax notice 2023.
