How to start a business in New Caledonia: the 2026 steps

Registration, business tax, social security and consumption tax: the steps to start a business in New Caledonia, in the right order, with the deadlines that matter.

By Benjamin Forte · 19 October 2026 · 7-minute read

If you want to start a business in New Caledonia, the paperwork itself is quick. What needs planning is the series of registrations that follows, each with its own deadline: RIDET (the business register), the patente (local business tax), CAFAT (New Caledonia’s social security fund) and TGC (the local consumption tax). Missing one rarely hurts in the first month; the trouble comes later, when contributions and tax bills arrive unbudgeted.

The context calls for care. On 1 January 2025, ISEE, the territory’s statistics institute, counted 61,367 active businesses, 2.2% fewer than a year earlier, with a business creation rate of 1.9% in 2025. Starting up remains possible, provided you put figures on the project before you register.

This guide follows the actual order of the steps, using official pages from CCI, ISEE, the DSF tax department and CAFAT consulted in October 2026. Amounts change every year, so check them with each body before you commit.

Before the paperwork: test the idea and cost the project

Registration is the easy part. Two questions come first and shape everything after: will customers pay, and how much do you need to keep going until the first payments come in?

Test your offer with ten or so potential customers: price, lead time, and what would make them switch supplier.
List your start-up costs: equipment, premises, vehicle, software, stock, insurance, website.
Build a 12-month cash-flow plan that includes the patente, CAFAT contributions and the CCS solidarity levy described below.
Identify your funding: personal contribution, bank, interest-free honour loan, microcredit, provincial grants.

One timing point matters straight away. The South Province grants code only counts spending incurred after the province issues its receipt for a complete application (article 1121-2), so signing a quote too early can cost you a grant. Our Launching your business page explains how we prepare this stage.

Sole trader or company: choosing your legal form

As a sole trader (entreprise individuelle, often called a “patenté” locally), you trade in your own name. With a company (an EURL, an SARL or another form), you create a separate legal entity, with articles of association and an entry on the trade and companies register (RCS).

The choice has direct consequences for your social cover. According to CAFAT’s 2026 guide, the self-employed scheme covers:

sole traders in any field: retail, crafts, services, liberal professions;
SARL managers who together form a majority management, holding more than 50% of the shares;
a majority shareholder who does not manage an SARL or EURL subject to corporation tax, if paid by the company.

A minority or equal-share manager, by contrast, falls under the general scheme, like an employee. Note also that self-employed people are not required to pay into a pension; CAFAT offers voluntary cover, subject to conditions.

Tax, liability and accounting costs also differ from one form to another. Have your choice checked by a chartered accountant before you file.

The right office: CCI, CMA or Chamber of Agriculture

Registration goes through a business formalities centre (CFE), chosen according to your activity:

CCI (Chamber of Commerce and Industry): commercial, industrial and transport activities, and now also liberal professions and certain services provided in your own name;
CMA (Chamber of Trades and Crafts): craft businesses with fewer than 10 employees;
CAP-NC (Chamber of Agriculture and Fisheries): farmers and professional fishers.

Part of the process can be done online. Launched in 2019 for sole traders, the public platform guichet-entreprises.nc has also allowed SARLs and EURLs to be set up online since September 2024, and it includes a patente simulator. RCS formalities are handled on infogreffe.nc.

Official sources do not agree on which cases can be handled online: ISEE limits online creation to companies, while CCI and CAFAT mention it for sole traders. Call your CFE to find out which route applies to you.

RIDET, RCS, patente: what each registration triggers

RIDET, the business identification register kept by ISEE, gives your business its identity. Registration is compulsory for companies and sole traders alike. CCI advises registering before you start trading, so that you hold your RIDET notice and, if you are on the RCS, your K-bis extract.

The patente is the annual tax on carrying out a business activity. According to the DSF, a new activity must be declared within fifteen days of starting, and the tax is only due from the first day of the month in which you begin.

The amount depends on factors such as your trade, the municipality, the floor area of your premises and your commercial vehicles. The fixed portion is reduced by 25%, and additional local levies are added. The simulator on guichet-entreprises.nc gives you a figure to put in your budget.

RUAMM: social cover for the self-employed

If you fall under the self-employed scheme, you must register with RUAMM, the health insurance scheme run by CAFAT, within 30 days of starting your activity.

First year: the provisional contribution is a flat amount based on the SMAG, the minimum agricultural wage (142,462 XPF at 31 December 2025 in the guide’s example).
Order of magnitude: for the first half of 2026 and 2025 income below 1,709,544 XPF, the guide shows 17,095 XPF per quarter for partial cover or 23,506 XPF for full cover, plus 12,822 XPF of CCS.
Cover: partial cover pays only for certain major treatments; full cover pays for all care at RUAMM rates. Access to full cover depends partly on how many quarters you have contributed in the past.
CCS (the Caledonian solidarity contribution): 3% from the first franc, with no ceiling. For an activity started in 2026, it is only claimed from the third quarter of 2027.
Payment: quarterly, before each quarter begins (31 December, 31 March, 30 June, 30 September).

Contributions are later adjusted to your actual income. Set aside part of your takings every month so that the adjustment does not catch you out.

TGC: basic exemption or standard scheme

TGC, the general consumption tax, is New Caledonia’s equivalent of VAT. According to the DSF page, last updated in 2019, a business qualifies for the basic exemption (franchise en base) if its turnover stays below 25 million XPF for sales of goods and building work, or 7.5 million XPF for services.

Under the exemption, you charge no TGC, but you cannot recover the TGC you pay on purchases either. You can opt for the standard scheme from the moment you register; the DSF states that this choice is irrevocable.

Opting in can make sense if you invest heavily at the start and your customers are businesses that recover TGC. In January 2025 the Congress dropped a plan to lower the exemption thresholds, and since July 2025 the exemption no longer applies to property sales. Confirm the current thresholds with the DSF before you decide.

Start a business in New Caledonia: your 90-day checklist

Before registering: offer tested, start-up budget, 12-month cash-flow plan, legal form checked with an accountant.
Before any grant-eligible spending: grant applications filed, since the South Province does not count spending made before the application is complete.
Day 0: file submitted to the CFE or online, TGC option decided, RIDET notice (and K-bis for a company) filed away.
Within 15 days of starting: patente declaration.
Within 30 days: RUAMM registration, choice of cover and of the optional cash-benefits cover.
First month: dedicated bank account, quote and invoice templates, insurance suited to your activity.
Every month: provision for CAFAT, CCS and the patente, and a comparison of actual cash with the forecast.

An outside view before you sign helps you correct course before money is committed. That is the purpose of our Éclairer diagnostic.

Key point

Cost the project and file grant applications before spending anything, then meet two deadlines: 15 days to declare the patente and 30 days to register with CAFAT.

Frequently asked questions

Can I start a business online in New Caledonia?

Partly. The guichet-entreprises.nc platform has handled sole-trader formalities since 2019 and the creation of SARLs and EURLs since September 2024; RCS formalities can also be done on infogreffe.nc. Official sources differ on which cases are covered, so check with your CFE.

Do I have to charge TGC when I start?

Not if your turnover stays below the basic exemption thresholds, which the DSF gives as 25 million XPF for goods and 7.5 million XPF for services. You can, however, opt for the standard scheme when you register, and that choice is irrevocable.

How long do I have to register with CAFAT as a self-employed worker?

Thirty days from the start of your activity, according to CAFAT’s 2026 guide. The patente must be declared within fifteen days.
