Cheapest accounting options in Luxembourg

Sole trader

The sole trader structure (Indépendant or Sole Proprietorship) is considered the most cost-effective option for a start-up. The main advantage is that there is no need to raise share capital or pay notary fees during registration. From an accounting perspective, this status offers the most flexible framework.

For sole traders whose annual turnover does not exceed €100,000 (excluding VAT), the law provides for the option of using so-called simplified accounting (Comptabilité simplifiée). This method is based on the cash basis, whereby only actual cash receipts and payments are recorded. Such entrepreneurs are exempt from the obligation to file annual financial statements with the Trade and Companies Register (RCS), which eliminates the need for costly services to prepare balance sheets and profit and loss accounts for public access.

Limited Liability Company

The introduction in 2016 of a simplified form of limited liability company (SARL-S) has radically transformed the landscape for budding entrepreneurs. It allows a fully-fledged legal entity to be established with capital ranging from €1 to €12,000 without the need for the articles of association to be notarised, saving the founder between €1,000 and €2,500 at the start-up stage.

However, it is important to note that, unlike a sole trader, an SARL-S is required to keep accounts using the double-entry method (Comptabilité en partie double) regardless of its turnover. This means that it must comply with the Standard Chart of Accounts (PCN), prepare an annual balance sheet and submit it to the RCS via the eCDF platform. As a result, the ongoing costs of running an SARL-S may be higher than those of a freelancer, due to stricter requirements regarding documentation.

Luxembourg’s traditional fiduciary services market

Fiduciaries in Luxembourg are certified providers of accounting and tax services. Historically, their fees have been geared towards medium-sized and large businesses; however, there has recently been a rise in services tailored to small businesses.

Price categories and modular rates

The cost of a fiduciary company’s services in Luxembourg is rarely fixed and usually depends on the volume of transactions, the complexity of the tax structure and the need to prepare special reports. For small businesses (VSE/SME), standard rates are as follows:

• Basic bookkeeping: entering source documents into the system can cost from €120 per month for micro-enterprises.
• Comprehensive support packages: for start-ups with a turnover of up to €50,000, packages range from €450 to €750 per month. These packages typically include monthly bookkeeping, reconciliation of bank statements and basic VAT reporting.
• Annual accounts: the preparation and submission of annual accounts is charged as a separate service, with prices starting at €500 and rising to €1,200 or more, depending on the quality of the bookkeeping throughout the year.

Many companies, such as Financial Services Accountant Luxembourg, offer an 8% discount for annual prepayment and guarantee a price freeze for 24 months, enabling businesses to plan their budgets more accurately.

Freelance Accountants

An alternative to fiduciary firms are independent chartered accountants. The average hourly rate for such a specialist in Luxembourg is approximately €24.12. By comparison, engaging a large fiduciary firm can cost between €200 and €450 per hour for high-level consultancy services.

Hiring a freelancer is beneficial for business owners who are prepared to handle the initial collection and sorting of documents themselves, leaving the specialist to simply check and submit the official returns. This allows annual accounting costs to be reduced to between €500 and €900 per year, provided that only the annual income tax return and ICC are involved.

Automation as a way to save money

The most cost-effective accounting solutions today are digital in nature. The emergence of cloud-based platforms integrated with Luxembourg’s government systems has reduced the need for human intervention in routine tasks, leading to lower costs.

EasyBiz

EasyBiz offers a unique model that combines cloud-based software with support from certified accountants. This solution is designed for those who want the protection afforded by a full-service accounting firm, but at the prices of a digital service.

• Price: the basic package starts at €99 per month (excluding VAT).
• Services included: bookkeeping, filing VAT returns, preparing annual accounts for the Companies Register, and the annual tax return.
• Features: the platform provides access to optical character recognition (OCR) tools and direct integration with bank accounts via Open Banking.

For entrepreneurs operating through an SARL-S, this solution is often the most balanced option, as it covers all legal obligations at a cost comparable to the minimum fee charged by a standard accountant.

Tax compliance and reporting thresholds

Understanding Luxembourg’s turnover threshold system enables businesses to legally avoid unnecessary administrative costs.

VAT regime

VAT obligations in Luxembourg depend on annual turnover. Choosing the right scheme is key to saving money.

Each additional tax return filed through a traditional accountant can cost between €50 and €150. Therefore, managing your business’s annual accounts significantly reduces the administrative burden.

Digital infrastructure: eCDF and LuxTrust

A significant proportion of the cost of services provided by Luxembourg accountants stems from the need to use specific government portals. However, business owners can carry out some of these tasks themselves.

The eCDF (Electronic Compulsory Data Filing) platform serves as the central hub for the collection of financial data. Since January 2016, its use has been mandatory for all companies and sole traders submitting VAT returns or annual balance sheets.

Self-submission via eCDF

You do not need to be a qualified accountant to use the system. Sole traders can register for a personal account using a LuxTrust certificate (Private or Pro). The main steps are:

• Obtaining a LuxTrust certificate (costing from €130 for a business solution).
• Creating an administrator account on the ecdf.lu portal.
• Filling in standardised PDF forms or uploading XML files generated by accounting software (such as Odysya or Accountable).

Using software capable of exporting data in eCDF-compatible XML format is the most effective way to save on fiduciary services. This eliminates the need for manual data entry by a specialist, for which an hourly fee is usually charged.

Banking services as a hidden component of accounting costs

The cost of bookkeeping is closely linked to how easily bank transactions can be integrated into the accounting system. Traditional banks in Luxembourg (BCEE, BGL) often have complex interfaces and charge high fees for data downloads or the management of business accounts.

Modern neobanks and EMIs (Electronic Money Institutions) offer cheaper alternatives that directly reduce the workload of accountants (and therefore their costs):

Using banks that grant accountants read-only access enables them to reconcile accounts more quickly, without requiring the business owner to constantly send over statements.

2024–2025 Reform: Changes to Business Categorisation Thresholds

In 2024, legislative changes came into force in Luxembourg, revising the criteria for classifying companies by size. This has a direct impact on accounting costs, as a company’s category determines whether a statutory audit is required.

Small companies are not required to undergo an audit if they do not exceed two of the following three criteria for two consecutive years:

• Total balance: up to €7.5 million.
• Net turnover: up to €15 million.
• Average number of employees: up to 50.

Raising these thresholds (previously, the balance sheet limit was 4.4 million and the turnover limit 8.8 million) has enabled a greater number of companies to remain in the ‘small’ category, thereby exempting them from the requirement to appoint an external auditor (Réviseur d'entreprises agréé), whose services are significantly more expensive than those of a standard accountant.

The general trend in the Luxembourg market suggests that savings on accounting costs are now achieved not by seeking out the cheapest specialist, but by minimising the time they spend on the job. Outsourcing the collection of documents and the initial classification of transactions to artificial intelligence algorithms and cloud platforms allows small businesses to reduce their administrative costs by 40–60 per cent compared to traditional support methods. Thus, the most cost-effective option is a combination of modern fintech infrastructure and a well-informed choice of legal structure for conducting business.
