Hayot Expertise Paris 8: news, services and 2026 updates

Updated April 2026 — A firm such as Hayot Expertise should not be reduced to bookkeeping alone. Located at 58 rue de Monceau in the 8th arrondissement of Paris, the firm supports SME directors, startups, freelance professionals and property investors with a proactive advisory approach that goes well beyond producing accounts. Its news and publications offer a window into how it reads the tax, payroll, legal and management topics that genuinely matter to business owners.

The chartered accountancy (expert-comptable) profession in France is governed by Ordinance No. 45-2138 of 19 September 1945, which established the Ordre des experts-comptables and regulates the title and the profession. As of 2026, France has 21,611 chartered accountants registered with the Order and nearly 19,500 accounting firms, according to data from the National Council of the Order (CNOEC). The sector employs over 186,000 people, making it the largest employer among the liberal professions in France, with total revenue estimated at between €16 and €17 billion.

This context is marked by a profound transformation. 77% of companies now use a chartered accountant, up from 71% in 2019. But expectations have shifted: 88% of companies believe that firms should communicate more about their skills beyond traditional accounting. This is precisely the space where the added value of a firm like Hayot Expertise lies.

Traditional missions — bookkeeping, preparation of annual accounts and tax returns (liasse fiscale) — still account for two-thirds of firm revenue. But the share of management consulting, tax advisory and strategic support is growing steadily, reaching up to 35% of revenue for some firms.

A modern accounting firm should:

• secure legal, tax and social obligations in an increasingly complex regulatory environment;
• inform business decisions through proactive and personalised financial analysis;
• help steer the business with relevant performance indicators and rigorous cash flow monitoring;
• translate regulatory changes into concrete actions, whether those concern e-invoicing, the progressive abolition of the CVAE, or the measures of the 2026 Finance Act.

Hayot Expertise insight: the right accounting firm is not only the one that produces compliant accounts. It is the one that helps the business owner read the environment more clearly and anticipate changes before they become constraints.

The year 2026 is a pivotal year for French businesses. Several major reforms are being rolled out and deserve particular attention.

E-invoicing: the 2026 rollout#

The e-invoicing reform is entering a decisive phase. All VAT-registered businesses will be required to issue and receive electronic invoices through approved dematerialisation platforms (PDPs) or the public invoicing portal (PPF). The timetable, consolidated by the 2026 Finance Act, mandates a progressive rollout starting with large companies and extending to micro-enterprises and SMEs. Accounting firms play a central role in supporting this transition, both on the technical side and in terms of ensuring the compliance of invoice flows.

Abolition of the CVAE#

The Cotisation sur la Valeur Ajoutée des Entreprises (CVAE) — a production tax levied on business value added — is being progressively abolished under the Finance Act. This measure represents a meaningful tax relief for businesses, but it comes with compensation mechanisms and a recalibration of other production taxes that need to be analysed on a case-by-case basis.

New accounting obligations#

The French Accounting Standards Authority (Autorité des Normes Comptables, ANC) had new regulations approved in 2025, entering into force in 2026, which modify certain rules on accounting presentation and measurement. These changes notably concern the treatment of certain financial instruments and the presentation of financial statements for small entities.

Hayot Expertise, led by Samuel HAYOT, a qualified chartered accountant and commissaire aux comptes (statutory auditor), follows this logic of comprehensive support. The firm's expertise covers every dimension of business life:

• Accounting and statutory audit: bookkeeping, preparation of annual accounts, statutory audit for companies subject to mandatory audit control;
• Tax: tax planning, tax return preparation, support during tax audits, structuring advice;
• Payroll and employment law: payroll management, social security filings, employment law advice, support for recruitment and restructuring;
• Legal: company formation, articles of association amendments, annual legal secretariat, governance advice;
• Management and advisory: management dashboards, financial forecasts, performance analysis, support for business creation and transfer.

This integrated, multi-disciplinary approach allows the firm to address business owners' challenges in their entirety, without fragmenting them across multiple contacts. It is a deliberate structural choice that responds directly to a telling reality: 53% of companies keep the same accounting firm for over ten years. That loyalty is built on the ability to understand the business in all its dimensions.

An accounting firm's publications are not a cosmetic exercise. They reflect several elements that are essential for any business owner looking to choose or evaluate an accounting partner.

Active regulatory monitoring. A firm that publishes regularly on tax, payroll and accounting developments demonstrates that it maintains up-to-date expertise. In an environment where the Finance Act reshapes the tax landscape every year, this monitoring is not optional — it is a core part of the advisory mission.

The ability to simplify. The quality of advice is also measured by the capacity to make complex technical information accessible. A business owner does not need to know the articles of the Code général des impôts; they need to understand the concrete consequences for their company.

Anticipation. The best news arrives before the deadline. Publishing on e-invoicing from early 2026, for example, allows businesses to prepare well before the effective entry into force. This logic of anticipation is what distinguishes a genuine partner firm from a reactive service provider.

The statistic is telling: more than half of French companies remain loyal to their accounting firm for over ten years. This loyalty stems from the very nature of the relationship. The chartered accountant knows the company's history, its seasonal patterns, its strategic challenges, its strengths and its vulnerabilities. They are able to place every piece of advice within a long-term perspective.

It is this in-depth knowledge that allows Hayot Expertise to offer tailored support, adapted to the reality of each business owner — whether that is an entrepreneur who needs to structure their accounting from day one, an SME director in growth mode who needs to professionalise their management, or a property investor seeking to manage the taxation of their assets effectively.

Hayot Expertise insight: do not choose your firm on price alone. The quality of the relationship, responsiveness, technical competence and the ability to anticipate are far more important criteria over the long term. A good firm saves you considerably more than it costs.
