How to calculate your tax back…

  • Select a tax year – you can only go back four tax years.
  • Enter your total gross pay.
  • Enter your total tax paid.

The tax refund calculator will give you an estimation of the refund you might be due if you have overpaid tax through your salary under PAYE.

If the calculator shows that you have not overpaid tax you may be due a refund for other reasons. In most cases you need to follow a specific process to claim back what you are owed otherwise your entitlement will not be refunded.

Please read on to find out more about tax refunds, the refund process and what you can do to make sure you don’t overpay income tax.

How does the Tax Refund Calculator work?

The main figures used to calculate a tax refund are:

1. The tax free personal allowance for the tax year. This means you only pay tax on earnings over the tax free allowance.

2. Any other income under PAYE for example from a pension.

3. Depending on how much you earn you can pay tax at different rates. The rates are currently 20%, 40%, and 45%.

4. Your tax code which can vary depending on different factors. If it’s wrong you can overpay or underpay tax. You can find out more about tax codes in our tax code guide.

The calculator does not take into consideration other reasons why you may have paid too much income tax. It will only let you know an estimate in circumstances where you have overpaid because of a reason like having an incorrect tax code or because you were made redundant.

Wondering how to estimate your 2022 tax refund?

Just answer a few simple questions about your life, income, and expenses, and our free tax calculator will give you an idea if you should expect a refund and how much, or if you’ll owe the IRS when you file taxes in 2022.


Do you work in the Netherlands and would you like to know the amount of tax you will get back or have to pay? You'll be able to find many tax calculators online, but unfortunately, they do not take things such as partial residency in the Netherlands (M-form), or income obtained in other EU countries (90 percent rule) into account. In these cases, the calculation is pretty complicated.

But here's some good news: Aangifte24 offers a calculator which can help you solve this problem in a few simple steps, in your native language! And more good news: there is no fee required to access this handy calculator!

Aangifte24 makes completing a tax return in the Netherlands easier

"Aangifte24.com is an application that was created for expats working temporarily in the Netherlands. People who are not registered residents or do not speak Dutch have great difficulty in understanding the tax regulations and submitting a tax return to the Belastingdienst. This is why we developed a tool for them, which is available in eight languages and makes completing a tax return in the Netherlands easier,” says Lucas Kirstein,  CTO of Aangifte24.com.

At the moment, the tax calculator is available in the following languages: English, German, Dutch, Russian, Polish, Czech, Greek, Croatian, Hungarian, Lithuanian, Romanian and Bulgarian.

How does it work?

So, how does this handy tax calculator from Aangifte24 work exactly? Well, after answering a few questions, a window will appear where you can enter data from the Jaaropgave. You will need to provide data such as your:

  • Income (loon)
  • Advance income tax payment (ingehouden loonbelasting)
  • Employee tax relief (arbeidskorting)

Then you will need to fill in the period of employment in the Netherlands and, in the next step, the income in other countries. Information about income is essential in order to determine eligibility for tax deductions, according to the 90 percent rule (non-resident taxpayer 90 percent rule).

If you want to calculate your entitlement to zorgtoeslag, this can also be done by providing the date from which you want to apply for the subsidy. At the end, the application presents the calculated amounts. If the data in the application is correctly filled in, the amount will be very close to the actual aanslag tax decision that you will receive from the Belastingdienst.

Aangifte24: Do your Dutch taxes the easy way

The increasing complexity of tax law in Europe and the Netherlands makes the calculation of your tax very complex. The tax calculator from Aangifte24 takes into account such variables as:

  • Heffingskorting - calculation according to days insured (Premie Volksverzekeringen)
  • Premie Deel and Belasting Deel - calculation of the tax relief depending on the 90 percent rule
  • Arbeidskorting - calculation of the tax relief based on the period of employment and the 90 percent rule
  • Insurance premiums - taking into account the exemption from contributions (A1 form from another EU country)
  • Combinatiekorting - child tax credit and calculation according to the period of employment.

File your tax return online

Naturally, the process does not end with the calculation. You can finish filling in the data in the calculator or go directly to sending your tax return to the tax office. If you decide to send your tax return, you will be asked for additional information such as your BSN number, home address, telephone number and other details. Conveniently, this is all done online! Calculate your tax refund with Aangifte24 now!
