Payroll taxes in Belgium: An employer’s guide

When you hire in Belgium, you — as the employer — are responsible for calculating, withholding, and submitting payroll taxes from your team members’ pay slips. For some taxes, you are also required to make employer contributions.

In this article, we’ll explain clearly which taxes you need to withhold, which taxes you need to contribute to, and how to remit and make payments. So let’s jump straight in.

What is payroll tax?

Payroll taxes are the contributions employees and businesses make to the government to fund public programs, such as retirement, healthcare, and unemployment insurance. They typically include income tax and social contributions, and are set at pre-determined rates.

These rates (and the rules governing them) vary by country, but it’s every employer’s responsibility to ensure they are compliant, and that they are withholding and submitting the correct amounts.

What is the difference between payroll taxes and corporate taxes?

Generally, payroll taxes are tied to your employees’ wages, while corporate taxes are based on your company’s profits. 

Which payroll taxes do you need to withhold from your employee in Belgium?

In Belgium, the taxes you’ll need to withhold are:

Income tax

Belgian residents are taxed at a progressive rate of between 25% and 50%, depending on their level of income. You must withhold taxes from their pay slip based on these rates.

When to pay: Payments are due by the 15th day of the following month.

Employee social insurance contributions

Employees must contribute 13.07% of their gross salary to social security, covering benefits like healthcare, pensions, and unemployment insurance.

When to pay: Advance payments are due monthly.

Note that you may also be required to withhold additional taxes for certain employees, such as child support payments, student loan repayments, or any other court-ordered garnishments.

Which payroll taxes does your business need to contribute to?

As well as withholding the contributions listed above, you are also required to make your own contributions, as follows:

Employer social insurance contributions

As the employer, you must contribute approximately 27% of your employees’ gross salary to the social security system.

When to pay: At the same time as your employees’ contributions (see previous section).

How do you remit and pay payroll taxes in Belgium?

You must first register with the Belgian National Social Security Office (NSSO) and the tax authorities, and obtain a tax ID number. For each pay period, you must:

1. Calculate the correct amounts for withholding. If you use Remote Payroll or Remote EOR, we will do this for you.

2. Remit the withheld taxes and employer contributions to the respective authorities by the specified deadlines, typically via bank transfer.

3. Submit periodic declarations detailing wages paid and contributions due to both the NSSO and tax authorities.

How do you manage payroll taxes as an international employer?

When you hire a Belgium-based team member from abroad, there are several ways you can manage their payroll and payroll taxes.

If you already have your own legal entity in Belgium, you can:

• Handle it in-house. You can hire your own payroll tax specialists and manage everything internally. This can be costly, however.

• Use a local third party. You can hire a local firm to handle payroll, although this can be unreliable, costly, and pose data risks.

• Use a PEO. A professional employment organization (PEO) acts as an outsourced HR provider, and includes payroll.

• Use a global payroll provider. Global payroll providers — like Remote — have local specialists in multiple countries, ensuring that you are fully compliant with all tax requirements in each one. This is especially convenient if you have (or plan to have) employees in different countries, as you can manage all of them through one platform.

If you don’t have your own entity in Belgium and you still want to hire there, you can:

• Set up your own entity. This can be extremely costly and time-consuming, but if you plan on establishing your business long-term in Belgium, it might be a viable approach. To pay your employees, you would then need to choose one of the options above.

• Use an EOR. Employer of record (EOR) providers — like Remote — enable you to quickly and easily hire anywhere in the world, and also handle all the core HR functions (such as compliance and payroll). As well as being generally more cost-effective than opening your own entity, this option is highly scalable and, again, enables you to streamline all your global HR tasks in one place.

EOR, Payroll, or both: What does your business need?

Understand the difference between EOR and payroll services — and clarify which one your business needs to pay your international team members.

What about independent contractors?

In Belgium, independent contractors are classified differently to employees. As a result, they (in most cases) are responsible for calculating, managing, and paying their own taxes.

However, it’s crucial to understand the difference between contractors and employees, as you may inadvertently create misclassification risk. This can result in severe fines and penalties for your business. Learn more about hiring contractors in Belgium.
