Help to create your business from A to Z

Updated April 2026 - You are looking for help to create your business from A to Z and you come across hundreds of articles, simulators and contradictory advice. We'll get straight to the point.

The creation of a business in 2026 is based on six pillars: the choice of legal status, the financial aid available, the business plan, administrative formalities, financing and management of the first months. This guide details each step with up-to-date figures and procedures.

In summary: to create your business in 2026, you must choose a legal status adapted to your project, benefit from the ACRE to reduce your social charges the first year, put together a realistic business plan, carry out your formalities on the INPI one-stop shop, identify your sources of financing and set up cash flow monitoring from the first day.

Legal status determines your social treatment, your taxation, your responsibility and your ability to raise funds. This is the first structuring arbitration.

Micro-enterprise (self-entrepreneur)#

The micro-enterprise remains the simplest régime for starting an independent activity. Its advantages are real:

• creation in a few minutes on the one-stop shop;
• social security contributions calculated on actual turnover;
• simplified déclaration and payment via URSSAF;
• franchise based on VAT possible below the thresholds.

The ceilings for 2026 are 188,700 euros for activities selling goods and 77,700 euros for the provision of services and liberal professions. Beyond that, the régime automatically switches to the real régime.

The main trap: contributions are calculated on turnover, not on profit. If your expenses are high, micro-business can become punishing.

The individual enterprise (EI)#

Since the 2022 reform, the individual company benefits from an automatic séparation between professional assets and personal assets. This legal protection is real progress.

The EI allows you to:

• deduct your actual expenses from your turnover;
• opt for the liberal payment of income tax;
• benefit from ACRE under eligibility conditions.

This régime is suitable for artisans, traders and liberal professions whose activity generates significant expenses or exceeds the micro-enterprise thresholds.

The SASU#

SASU is a simplified joint stock company with a single shareholder. It has several interests:

• the president is considered an employee and is covered by the general Social Security régime;
• the president's rémunération is déductible from the corporate income;
• the structure is scalable and facilitates the entry of partners or investors.

On the other hand, the social cost is high: around 75 to 80% of net salary in contributions. If you do not pay yourself any rémunération, the contributions are zero, but you do not validate any social rights.

The SARL (or EURL if single partner)#

The SARL is the most common corporate form in France. The majority manager is covered by the self-employed worker régime (TNS), with a social cost of around 45% of net salary.

The SARL is recommended when:

• you create with several partners;
• you want to optimize the rémunération/contributions ratio;
• your project does not plan to raise funds from external investors.

Quick comparison table#

Hayot Expertise advice: never choose a status solely to benefit from one-off help. The status must correspond to your trajectory over 3 to 5 years, not just to your starting situation.

Aid for business creation can represent several thousand euros in savings or additional cash flow. Here are the two main devices.

L ACRE: reduction in social charges#

ACRE (Aid for Business Creation or Resumption) offers partial exemption from social security contributions for the first twelve months.

In 2026, the system works as follows:

• 50% reduction in social security contributions in the first year;
• applicable to micro-enterprise creators, EI, SASU, EURL and certain companies;
• the exemption ceiling is based on a fraction of the PASS 2026 (Annual Social Security Ceiling);
• allocation is automatic for job seekers compensated by France Travail, otherwise it is subject to an admissibility examination.

Potential beneficiaries include job seekers, young people under 26, RSA beneficiaries, résidents of QPV and ZRR, as well as creators in rural revitalization zones. To find out more: Service-Public.fr - ACRE.

L ARCE: capitalization of your unemployment rights#

ARCE (Aid for Resumption or Business Creation) allows you to receive part of your remaining unemployment insurance rights in the form of capital.

The 2026 rules:

• 60% of the remaining rights are paid in two installments (half upon creation, half six months later);
• payment is subject to obtaining ACRE;
• you waive the monthly maintenance of the allowance during the period concerned.

The trade-off between ARCE and maintaining benefits depends on your immediate cash flow needs. If your project requires a significant initial investment, ARCE may be relevant. If you need regular income during the launch phase, monthly maintenance is often preferable.

Other aid available#

• NACRE: support and honorary loan for people far from employment;
• regional aid: each region has specific mechanisms (subsidies, honorary loans, guarantees);
• Pole Emploi / France Travail: maintenance of benefits, childcare assistance;
• Bpifrance: seed loans and guarantees for innovative projects.

**Consult Bpifrance** Creation to identify the assistance adapted to your profile.

The business plan is much more than a document intended for the bank. This is your financial roadmap.

The essential components#

A solid business plan includes:

• market study: market size, competition, positioning, selling price;
• the commercial plan: acquisition channels, pricing strategy, turnover forecast;
• the initial financing plan: personal contributions, loans, subsidies, equipment needs;
• the forecast income statement: over 3 years, with detailed assumptions;
• the cash flow plan: month by month for the first year;
• the profitability threshold: minimum turnover to cover all costs.

Mistakes to avoid#

• overestimate turnover for the first months;
• forget the working capital requirement (WCR);
• do not provide a safety margin in cash flow;
• ignore customer and supplier payment deadlines.

Hayot Expertise Advice: a business plan is not an academic exercise. It is a living tool that you must update every quarter. Initial assumptions are rarely accurate, and that is normal.

Since 2023, all business creation formalities go through the INPI one-stop shop (National Institute of Industrial Property). This platform centralizes procedures that were previously distributed between several organizations.

The key steps#

1. Prepare the documents: identity document, proof of address, certificate of non-conviction, déclaration of effective beneficiary (for companies);
2. Submit the request on the one-stop shop;
3. Receive the Kbis (for companies) or the SIRENE situation notice;
4. Open a professional bank account (compulsory for companies, recommended for IEs);
5. Take out professional insurance (professional civil liability at a minimum).

Deadlines and costs#

• Registration deadline: 1 to 4 weeks depending on the legal form and completeness of the file;
• Registry fees: around 200 to 400 euros for a company;
• Legal advertising costs: between 150 and 250 euros depending on the newspaper chosen.

Pieces not to forget#

• the statutes for companies (SAS, SARL);
• the déclaration of exemption from seizure for the IS if necessary;
• authorization to exercise for regulated activities;
• the commercial lease or the domiciliation certificate.

Financing is often the main sticking point. Here are the main avenues.

Personal contribution#

This is the first source of financing expected by banks. A personal contribution generally represents 20 to 30% of the initial financing plan. It demonstrates your commitment and reassures lenders.

The professional bank loan#

Banks examine:

• the coherence of the business plan;
• the quality of the personal contribution;
• your experience in the sector;
• the guarantees offered.

In 2026, professional loan rates will be in the range of 4 to 7% depending on the profile and duration.

Honorary loans#

Offered by the Initiative France, Reseau Entreprendre or Bpifrance networks, these loans without personal guarantee strengthen your contribution. They are often accompanied by support.

Aid and subsidies#

• investment aid for local authorities;
• tax credits (CII for innovation, CIR for research);
• European subsidies depending on the nature of the project.

Creation is only the beginning. The first six months are decisive for the sustainability of the company.

Essential indicators#

• available cash flow: to be monitored every week, not every month;
• average customer payment deadline: an extension is a warning signal;
• gross margin: to check the economic viability of your offer;
• transformation rate: to measure commercial efficiency;
• profitability threshold reached or not: the most important indicator.

Best practices from the start#

• strictly separate professional accounts and personal accounts;
• invoice for delivery of the service or product;
• follow up on unpaid debts quickly and systematically;
• keep all supporting documents in a dedicated tool;
• take a weekly cash flow update for the first six months.

Accounting obligations#

Even in a micro-enterprise, you must:

• keep a recipe book;
• keep receipts for expenses;
• establish a quarterly or monthly turnover déclaration.

For companies, the obligations are heavier: complete accounting, tax returns, filing of annual accounts with the registry.

Our experience allows us to identify the most fréquent errors:

1. Choose an inappropriate status due to ignorance of the social and fiscal consequences;
2. Neglecting cash flow by focusing solely on turnover;
3. Forgetting to request ACRE within the allotted time frame;
4. Underestimate the WCR and find yourself in difficulty from the second month;
5. Mix personal and professional finances on the same account;
6. Do not anticipate taxation and discover the tax to be paid at the time of the déclaration;
7. Creating alone without advice when support would have helped to avoid structural errors.

Creating your business from A to Z in 2026 cannot be improvised. Between the choice of legal status, the mobilization of aid such as ACRE and ARCE, the construction of a realistic business plan, the formalities on the INPI one-stop shop and the management of the first months, every decision counts.

The most valuable help is not always financial. It is often the one that allows you to make the right decisions at the right time, with a clear vision of the social, fiscal and legal consequences.
