Due to indexation, in 2019 you can choose between two
maximum tax-deductible amounts: 980 euros or 1,260 euros. The maximum
amount is 980 euros by default, with
30% tax relief. That gives you a
tax credit of up to 294 euros on
what you deposit in 2019.
If you want to save more than that, you can opt specifically* for 1,260 euros as your cap for tax purposes. You'll qualify for 25% tax relief with a tax credit of up to 315 euros on what you deposit in 2019.
* Each year, you must decide on which arrangement to use. If you
opted for 1 230 euros in 2018, the lower maximum figure of
980 euros will apply as standard in
2019 (unless you explicitly opt for the higher figure of 1,260 euros).
