What is a personal income tax forecast?

Anticipate your taxes and know what your activity earns you

Written by Maud WAUTHOZ

The BILLY tax forecast estimates what your self-employed activity should leave you with net, after your expenses, social contributions and taxes.

To calculate this estimate, we start from your expected income and expenses for the year. We also take into account the main elements of your situation that can significantly influence your tax: salaried income, property income, alimony, copyright income,...

An estimate, not an early tax return

The goal is not to reproduce your entire future PIT return today. A forecast remains an estimate: your income, expenses and personal situation may still change.

A deliberately cautious approach

We take into account elements likely to significantly increase your tax. On the other hand, certain private tax benefits (service vouchers, pension savings, housing-related reductions, childcare costs,…) are not included.

The principle is simple: it's better to plan for a little too much tax and get a pleasant surprise at the final settlement than the other way around.

The final amount of your tax may therefore differ from the forecast. It is above all a tool to plan ahead, know how much to set aside and make good decisions for your activity.
