What if my income as an entrepreneur varies?

Then you adjust your contribution. In quiet months you deposit less or pause temporarily; after a strong quarter you top up. Pausing is free and you can resume at any time.

Many entrepreneurs deliberately wait until year-end, once profit is known, and then deposit their full jaarruimte in one go. In the app you see in real time how much room is left, so you don't exceed the fiscal limit. Calculate with the jaarruimte calculator.
