Introduction
Crypto tax in New Caledonia often surprises those who expect to apply mainland rules. The territory has broad fiscal autonomy: it has its own income tax and does not use the 30% flat tax (the PFU) known in mainland France. A crypto capital gain is therefore handled by a local progressive scale, not by a flat rate. This module walks you through how it works, with an indicative order of magnitude to estimate your tax, and reminds you where to declare. Important: this content is educational, not personal tax advice — for your own situation, consult an accountant or tax adviser, and check with the New Caledonia tax authority (Direction des Services Fiscaux).
The principle: fiscal autonomy, no flat tax
New Caledonia is not subject to mainland taxation. The territory has broad fiscal autonomy: it sets its own income tax and does not adopt the 30% flat tax (the PFU) that applies in mainland France.
In practice, it is not a flat "crypto" rate that applies, but the local progressive personal income tax (the local IRPP). This scale is progressive: it rises in brackets, from roughly 0% for the lowest incomes up to roughly 40% for the highest brackets.
This progressive logic changes everything compared with the mainland: the higher your taxable income, the higher the top bracket that applies to your gain. There is no automatic withholding at a single rate.
- New Caledonia has broad fiscal autonomy: it does not adopt the mainland flat tax.
- It is the local progressive income tax (local IRPP) that applies.
- The scale is progressive, from roughly 0% to roughly 40% depending on the bracket.
It's France, so the 30% flat tax (the PFU) also applies in New Caledonia.
Actually : No. New Caledonia has fiscal autonomy and applies its own local progressive income tax, not the flat tax. The scale runs from roughly 0% to 40%, not a flat 30% rate.
How a gain is treated under the progressive scale
A crypto capital gain realised by a New Caledonia resident is, in principle, caught by this local progressive income tax. The gain is folded into the scale, and the bracket reached determines the real tax burden.
To help you get a sense of it, you can use a purely educational order of magnitude of about 25% on the gain. This figure is not a fixed official rate: it serves only as a benchmark to estimate, because the real result depends on your bracket in the local scale.
- A crypto capital gain is, in principle, subject to the local progressive income tax.
- The gain is added to your other income and the bracket reached sets the tax burden.
- Educational benchmark: about 25% on the gain — an indicative figure, not a fixed official rate.
- The real result depends on the local scale (roughly 0% to 40%) and on your situation.
The local currency (XPF) and a figure that is only indicative
In New Caledonia, the local currency is the CFP franc (code XPF). Income and the local tax calculation are expressed in this currency, which adds a step compared with reasoning in euros.
Above all, keep in mind that the figures in this module are educational benchmarks. The ~25% mentioned on the gain is only an order of magnitude to help you estimate; it does not replace the official scale.
An indicative figure, to verify locally
The ~25% used here on the capital gain is purely indicative: the local scale is progressive (roughly 0% to 40%) and the currency is the CFP franc (XPF). Always verify your situation and the exact scale with the New Caledonia tax authority, the Direction des Services Fiscaux (dsf.gouv.nc).
Declaring to the DSF, and the role of a French account
In New Caledonia, it is up to you, the resident, to correctly declare your gains to the Direction des Services Fiscaux de Nouvelle-Calédonie (the DSF). It is this authority, not the mainland tax administration, that manages the local income tax to which your capital gain is attached.
Deblock is regulated in France, not in New Caledonia. That changes nothing about your obligation: the account does not declare on your behalf and removes no local tax obligation. As a New Caledonia resident, it is up to you to declare your own gains according to the local scale.
Because the calculation depends on the progressive scale and is done in CFP francs, the right reflex is to keep the history of your operations (dates, amounts) and, at the slightest doubt, to consult an accountant or tax adviser. Official source: Direction des Services Fiscaux de Nouvelle-Calédonie (dsf.gouv.nc).
- You declare your own gains to the Direction des Services Fiscaux de Nouvelle-Calédonie (DSF).
- Deblock, regulated in France, never declares on your behalf and removes no local obligation.
- Keep the history of your operations (dates, amounts) to justify your calculation.
- At the slightest doubt, consult an accountant or tax adviser.
What you should remember
- 01New Caledonia has broad fiscal autonomy: it does not apply the mainland flat tax.

- 03Educational benchmark: about 25% on the gain, an indicative figure in CFP francs (XPF), to verify locally.
- 04New Caledonia resident = you declare yourself to the DSF; Deblock does not. Educational content, not tax advice — consult an accountant or tax adviser.

Crypto tax by country
How your crypto gets taxed at home
Every country where Deblock is available has its own tax reading. This section gives an educational reference point before any simulation. Your real case depends on tax residence, annual transactions and your status.
France: 30% flat tax with €305 disposal exemption
For a French tax resident, selling crypto for euros, paying with crypto or converting into a good/service triggers taxation. Crypto-to-crypto swaps are generally neutral.
Simplified calculation
- If annual disposals ≤ €305: no tax.
- Gain = disposal price − weighted total acquisition price across the portfolio.
- 30% flat tax by default: 12.8% income tax + 17.2% social contributions.
- Optional progressive income tax scale if more favourable.

30% total, no allowance. Simple to compute, this is the simulator's default.
Progressive option
Available since 2019. Only useful if your marginal income tax rate is very low or if you have losses to offset.

The administration looks at total disposal price, total acquisition cost and total portfolio value at disposal — not line-by-line by coin.
