Whether you are the manager of an SME, a self-employed professional, or an accounting officer, knowing how to calculate VAT on your invoices saves you costly mistakes and ensures a smooth declaration. Through this guide, discover how to go from excluding tax (ET) to all taxes included (ATI), vice versa, know the applicable rates, and comply with associated tax obligations, relying on clear and easily applicable methods.
This know-how goes far beyond a simple mathematical operation: it is a true lever in the company’s accounting organization and financial strategy. Today, mastering VAT means taking control of your tax management with rigor, without getting lost in administrative complexities. Deepen your understanding with concrete cases and practical tips so that calculating VAT becomes a confident reflex, within reach for your daily invoices and tax declarations.
In brief:
- 📌 VAT applies according to several distinct rates (20%, 10%, 5.5%, 2.1%) related to the nature of goods and services.
- 📌 VAT calculation is based on simple but essential formulas: multiply the ET by the rate to get the VAT, add the VAT to the ET to get the ATI, and conversely extract the ET from the ATI.
- 📌 Rigorous management and good organization facilitate VAT declaration and prevent errors as well as tax adjustments.
- 📌 Tracking collected and deductible VAT represents a crucial balance to reduce the amount to be paid to the State.
- 📌 Digital tools, spreadsheets, and online calculators significantly simplify this complex process.
Mastering VAT rates: understanding the different applicable percentages in 2026
The first step to calculating VAT is knowing the specific rates in effect, because applying an incorrect rate will distort all your calculations and cause complications in tax declarations. In 2026, France continues to apply several distinct rates, established according to the nature of the good or service concerned.
The standard 20% rate, an essential benchmark
This rate primarily applies, covering service provisions, manufactured products, and most consumable goods. For example, a consultant invoicing an intellectual service or a company selling computer equipment will apply the 20% rate. This rate thus constitutes the basis for many VAT calculations.
Reduced rates, for strategic sectors
The intermediate 10% rate concerns specific fields such as catering excluding alcoholic beverages, some public transport, or housing renovation. It is a support measure that limits the tax burden on sectors with a strong social impact.
The reduced 5.5% rate targets essential products such as basic foodstuffs, books, or domestic energy. This reduced rate aims to facilitate access to vital resources at a lower cost for end consumers.
Finally, the super-reduced 2.1% rate is reserved for a very specific list of products such as certain reimbursed medicines or press publications. These rates represent an often little-known but crucial exception for certain professionals.
| 💡 Type of VAT | 🔢 Rate in % | 📋 Examples of application |
|---|---|---|
| Standard rate | 20% | Service provisions, electronic equipment, clothing |
| Intermediate rate | 10% | Catering, public transport, renovation works |
| Reduced rate | 5.5% | Basic food products, books, domestic energy |
| Super reduced rate | 2.1% | Reimbursable medicines, press |
Precise knowledge of these VAT rates helps avoid errors during invoicing and ensures that the taxable base is correctly assessed. This rigor is the key to ensuring a compliant declaration and controlling the amount of taxes.
Calculating VAT from the excluding tax amount (ET): step-by-step method
In most cases, the starting amount of your invoice corresponds to the excluding tax amount (ET). Knowing how to go from ET to ATI is fundamental to establishing a clear and compliant quote or invoice. The calculation is based on the following formula:
VAT amount = ET Price × VAT Rate
ATI Price = ET Price + VAT amount
Let’s examine a concrete case: a company invoices a service at €1,000 ET, with a VAT rate of 20%. The VAT calculation is as follows:
- 1,000 € × 20% = 200 € VAT
- 1,000 € + 200 € = 1,200 € ATI
This direct calculation allows you to immediately know the amount to indicate on an invoice and facilitates entry into computer tools or management software. It is essential to accurately determine the taxable base, i.e., the ET amount, because any mistake at this stage will affect all fiscal operations.
Implications for your company’s management
A clear billing with ET, VAT, and ATI details avoids many surprises. It ensures not only transparency with the client but also prevents a common pitfall: an incomplete or non-compliant invoice that could lead to reprimands during a tax audit. It is also advisable to use appropriate tools, such as those presented on this invoice management site, which allow automating these calculations and securing the accounting chain.
Finally, it is imperative always to note the applied VAT rate and keep the mention of the intra-community VAT number if necessary. These good practices protect you against requests for supporting documents from administrations.
Calculating the excluding tax amount (ET) from the all taxes included amount (ATI)
When you only have an ATI price, whether for a purchase or a subcontracted service, it is essential to retrieve the excluding tax base in order to correctly value professional expenses and optimize your cash flow. The formula to use is as follows:
ET Price = ATI Price ÷ (1 + VAT Rate)
VAT amount = ATI Price – ET Price
Once again, the example reveals the simplicity of the approach: with an ATI price of €120 and a VAT rate of 20%:
- 120 € ÷ 1.20 = 100 € ET
- 120 € – 100 € = 20 € VAT
This calculation is all the more important for the declaration and deduction of VAT to which the company may be entitled on its professional purchases, respecting the specific associated rules. To facilitate expense tracking and VAT recovery, several solutions exist, including specialized platforms such as Cleemy to optimize expense reports or N2F for expense management.
Strict adherence to these formulas ensures not only sound management of your accounting but also reliable calculation of the tax to be paid to the tax administration.
Advanced management: collected VAT, deductible VAT, and final amount to pay
Beyond simple calculation on invoices, VAT plays a broader role in the functioning of cash flow and the fiscal management of a company. The difference between collected VAT and deductible VAT determines what the company actually has to pay in taxes.
What is collected VAT?
This is the VAT invoiced to clients on your sales. It corresponds to an amount to be collected for the State. Concretely, collected VAT is calculated on the total ET sales, multiplied by the applicable rate. For example, a company making €10,000 ET sales at 20% and €5,000 ET at 10% will have collected VAT of:
- 10,000 × 20% = €2,000
- 5,000 × 10% = €500
- Total collected VAT = €2,500
Deductible VAT, an essential lever
This is the VAT paid on your professional purchases, for which you hold proper invoices. This VAT is deducted from the collected VAT and reduces the amount to be paid to the State. Here is a simple example:
- Equipment purchases: €5,000 ET at 20% = €1,000 VAT
- General expenses: €2,000 ET at 20% = €400
- Fuel: €500 ET at 20% = €100
- Total deductible VAT = €1,500
At the end of the period, the VAT to pay is calculated as follows:
VAT to pay = Collected VAT – Deductible VAT
In the example, this results in:
€2,500 – €1,500 = €1,000
This mechanism is crucial for fiscal management and the financial health of the company.

Best practices for impeccable VAT management
Beyond formulas, proper VAT administration relies on several simple but vital rules for the company’s sustainability and peace of mind in the face of tax audits.
Rigorous organization and declaration
The first key is to scrupulously respect declaration deadlines. Up-to-date accounting, with clear filing of invoices by VAT rate, facilitates the entire process. Digitization plays a decisive role here to automate controls and reduce human errors.
Avoiding common mistakes
- 🚫 Always ensure the validity of the applied rate by referring to the general tax code.
- 🚫 Never round off imprecisely without rigorous method.
- 🚫 Keep all invoices and supporting documents in case of a tax audit.
Final advice: to integrate VAT calculation into your professional routine stress-free, consider using reliable tools and regularly verify your calculations, even with software. This will prevent facing unexpected tax notices.
How to know which VAT rate to apply on an invoice?
The applicable rate depends on the type of good or service. The standard rate is 20%, but some products or services benefit from reduced rates (10%, 5.5%, 2.1%). Always consult the General Tax Code or an updated guide to determine it precisely.
How to calculate VAT from a VAT-inclusive amount?
To find the excluding tax amount from the VAT-inclusive amount, divide the VAT-inclusive amount by 1 plus the VAT rate. The VAT is then obtained by subtracting the excluding tax amount from the VAT-inclusive amount.
What is deductible VAT?
Deductible VAT corresponds to the VAT you have paid on your professional purchases and that you can subtract from the collected VAT before paying the difference to the State.
What to do if you exceed the VAT exemption thresholds?
As soon as your turnover exceeds the thresholds, you must charge VAT, declare it, and pay the collected tax. It is important to manage this transition properly to avoid penalties and adjustments.
Which tools to use to simplify VAT management?
Billing software like Henrri, or expense management solutions such as Cleemy or N2F, allow you to automate calculations and secure accounting.
