Tax: none while you own it, none at the sale — T3 in Dammarie-lès-Lys — main home · ID 06Main homeNo rent → no income tax; gain exempt (CGI art. 150 U, II-1°)

Years 1 to 20: €0 of tax while you own it (no rent) and €0 at the sale (the gain is exempt).

Where each number comes from

This figure is calculated from the inputs only.

Part 1. While you own it: no tax

You live in the home: it earns no rent, so no income tax and no social contributions. The unspent down payment earns no interest here, so no flat tax either. The taxe foncière is not a tax on income: it is counted in what you pay each year (money lost).

Tax paid during ownership, years 1–20€0
Part 2. At the sale: the gain is exempt

The gain made when you sell your main home is exempt from income tax and social contributions (CGI art. 150 U, II-1°). The exemption is general: whatever the price, the size of the gain or the reason for the sale, and with no minimum holding period.

The conditions

  • It is your habitual and effective home: you live there most of the year (BOFiP BOI-RFPI-PVI-10-40-10 § 20–40).
  • It is not let, even to a tenant whose main home it is (§ 120).
  • It is still your main home on the day of the sale (§ 180).
  • If you move out to put it on sale, the exemption holds if the sale happens within a “normal period” (délai normal), in principle one year at most, and the home was neither let nor lent meanwhile (§ 190). That case is not calculated here.
