Since this year, holders of digital assets who have recorded capital gains in 2023 can choose between the single flat-rate deduction and the tax scale. condition of checking a new box present in the 2023 income tax declaration.
As you know, completing your tax return can be an obstacle course. And the task is even more difficult for holders of digital assets, such as bitcoin and other cryptoassets. Declaration of accounts, calculations of capital gains or losses… The road is long.
And at the end of the road, very often, you will have to pay. Until now, a holder of cryptoassets who would have realized a capital gain greater than 305 euros was obliged to pay the 30% tax on the single flat-rate levy (PFU), or flat tax. Or 12.8% income tax and 17.2% social security contributions.
The 3CN box, a new friend of your tax declaration
But good news: since January 1, 2023, the gains made are no longer necessarily subject to the PFU. Two choices are now available: the flat tax as was the case until now, or the progressive scale of income tax. An interesting change for taxpayers with little or no tax. Let’s take the example of a taxpayer who is not taxable in normal times: in the event of a capital gain during a sale of cryptoassets, the latter can today only pay the 17.2% social security contributions.
As a reminder, in the event of transfer of a digital asset for euros, you must complete a specific document, form 2086. And this, whether you have realized a capital gain or a capital loss during this transfer. Once the amount has been calculated, it is entered on your main income tax return (the usual 2042 form). Box 3AN must be completed in the event of a capital gain, box 3BN in the event of a capital loss.
And that’s where the new 3CN box comes in. So, if you do not wish to be taxed at the 30% flat-tax but at the income tax rate, you will need to tick this box. On the contrary, if you wish to be subject to flat tax, the 3CN box must not be checked. More precisely, the image of the 2OP box dedicated to bank investments, if you are not taxable, it is better to check the 3CN box. Beyond that, maintaining the single flat-rate deduction proves more judicious.
