France's National Assembly has backed a proposal to end tax deferral on certain cryptocurrency swaps, according to a report by TokenPost. The move targets a carve-out that currently lets French crypto holders exchange one digital asset for another without immediately triggering a taxable event.

What does the proposal change?

Under existing French rules, swapping one cryptocurrency for another can qualify for tax deferral, meaning the holder postpones recognizing a capital gain until the asset is converted into fiat currency. The Assembly-backed proposal would end that deferral for some swap categories, forcing gains to be recognized at the point of exchange rather than at cash-out.

The practical consequence is operational, not cosmetic. Traders who rotate between tokens — for example, moving between bitcoin and ether — would face an earlier tax liability on each conversion that loses deferral protection. French tax residents currently face a flat tax on crypto capital gains, and pulling the recognition date forward increases both the frequency of taxable events and the compliance burden on individual investors and trading platforms.

Who is affected?

The measure applies to French tax residents executing the affected swap types, provided the proposal survives the remaining legislative process. Institutional desks and retail traders operating through French-registered platforms would both need to adjust reporting workflows if the change becomes law.

A useful comparison: the deferral mechanism functions much like a like-kind exchange allowance, and its partial removal would move France closer to a transaction-by-transaction recognition model for the covered swaps.

What happens next?

The proposal still requires further legislative steps before it can take effect, including passage through the remaining stages of the French parliamentary process and, if enacted, implementation by the tax administration. Market participants in France will be watching the coming legislative calendar for confirmation of which swap categories lose deferral and when the first affected tax year begins.
