Hayot Expertise Paris 8: news and services 2026

Updated April 2026 — A firm such as Hayot Expertise should not be reduced to bookkeeping alone. Located at 58 rue de Monceau in Paris's 8th arrondissement, the firm supports SME owners, 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 profession in France is governed by Ordinance No. 45-2138 of 19 September 1945, which established the Order of Chartered Accountants and regulates the title and 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 liberal professions in France, with total revenue estimated between €16 and €17 billion.

This context is marked by 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 where the added value of a firm like Hayot Expertise lies.

Traditional missions — bookkeeping, preparation of annual accounts and tax returns — 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 it concerns 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 technically and in terms of flow compliance.

Abolition of the CVAE

The Value Added Contribution on Businesses (CVAE) is being progressively abolished under the Finance Act. This measure represents a significant tax relief for businesses, but it comes with compensation mechanisms and recalibration of other production taxes that need to be analysed on a case-by-case basis.

New accounting obligations

The French Accounting Standards Authority (ANC) has had new regulations homologated in 2025, entering into force in 2026, which modify certain rules of 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 statutory auditor, follows this logic of comprehensive support. The firm's expertise covers all dimensions of business life:

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

This multi-sector approach enables the firm to address business owners' issues holistically, without fragmenting them across multiple contacts. It is a structural choice that responds directly to the finding that 53% of companies keep the same accounting firm for over ten years: trust is built on the ability to understand the business in all its dimensions.

An accounting firm's publications and news are not a cosmetic exercise. They demonstrate several elements essential for a business owner looking to choose or evaluate their accounting partner.

Active regulatory monitoring. A firm that publishes regularly on tax, social and accounting developments demonstrates that it maintains up-to-date expertise. In an environment where the Finance Act modifies the tax landscape every year, this monitoring is essential.

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

Anticipation. The best news arrives before the deadline. Publishing on e-invoicing from early 2026, for example, enables businesses to prepare before the effective entry into force. It is this logic of anticipation that distinguishes a partner firm from a service-provider firm.

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

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

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

In 2026, the news published by an accounting firm creates real value when it turns technical information into useful decisions for the company. Hayot Expertise is committed to this approach: every publication, every piece of advice, every exchange with a business owner aims to make the complex accessible and the uncertain manageable.
