8 uses of tax ID in Germany

Uses of Tax Id in Germany

#1 Child benefit (Kindergeld in German)

Since January 2016, you must submit your and your children's tax identification number at the family benefits office (Familienkassen in German) to receive child benefits (Kindergeld in German).

#2 Maintenance payments

If you pay maintenance - for example, to your divorced spouse - and want to deduct the amount for tax purposes as a special expense, then you need the tax ID of the recipient (your divorced spouse).

#3 Fast data reconciliation

The tax identification number helps the tax authorities to access personal data quickly and easily.

For example, if you move to another city, the registration and tax offices can exchange your data via your tax ID.

Hence saving you time and effort.

Moreover, your tax-relevant data can be shared across national borders using the tax ID.

#4 Electronic income tax card

The electronic income tax card in Germany became possible because of the tax identification number.

Moreover, German employers can get all your tax-relevant data directly from the Federal Central Tax Office.

Hence, you don't have to worry about providing tax-relevant information to your employer.

#5 Electronic tax return (Steuererklärung in German)

Electronic tax returns (Elster) are possible thanks to the tax identification number.

Elster website checks the data for correctness as one enters. Thus, the tax office (Finanzamt) does not have to request tax-relevant information as often.

Hence, processing the tax return is faster.

#6 Pre-filled tax return (Vorausgefüllte Steu­er­er­klä­rung (VaSt) in German)

Since 2014, the German tax authorities have offered a service called "pre-filled tax return" (VaSt) to taxpayers filing tax declarations online.

Most of your tax-relevant data is already available digitally. Hence, it can be pre-filled in the income tax return form online.

Thus making filing tax declarations online easier for taxpayers.

The following data is available digitally to the German tax authorities :

  • name

  • address

  • age

  • religious affiliation

  • bank details

  • pension benefits

  • contributions to health and nursing care insurance

  • pension expenses, etc.

The service is also known as receipt retrieval (Belegabruf) or certificate retrieval (Abruf von Bescheinigungen).

To use the service, you need an Elster account. You can create one for free using your German tax ID on the Elster portal.

#7 Tax ID for an exemption order

Since 2011, banks have needed your tax identification number for exemption orders (Freistellungsauftrag in German).

Banks assign your capital gains (if any) to your tax ID for tax purposes. Hence making it possible that the bank doesn't have to withhold any taxes on your capital gains.

Thus allowing you to use your capital gains to invest further during the year and pay taxes when you file your annual tax return.

On the other hand, banks must withhold the withholding tax on interest payments and capital gains if they do not have your tax ID (exemption order).

The withholding tax is 25 percent of the capital gains, plus solidarity surcharge and church tax.

Hence, submit an exemption order containing your tax id to your bank.

#8 Link Tax ID with bank account

The federal government plans to link your tax ID to your bank account.

It will allow German public authorities to pay out state benefits more easily.

In the draft of the Annual Tax Act 2022, the German government announced that public services could pay out state benefits via direct payment method using the tax identification number.

The idea of linking tax ID with the bank account was originally to easily pay out the climate money (Klimageld).

But the government soon realized that linking tax ID with bank details can also be helpful in other places. For example, paying Energiepreispauschale (EPP) or relief amount during natural disasters.

However, as you can imagine, implementing the idea will take some time.

It is because the government has to store more than 80 million bank details (IBAN and possibly BIC) in the IdNr database along with the tax identification numbers.

Criticism of the tax identification number in Germany

Many people criticized using tax identification numbers in Germany based on data privacy.

#1 Civil rights objections

Civil rights activists fear that the Tax ID database can also be used for purposes other than tax.

However, the good news is that, per the current law, only the tax office may use this data.

#2 Tax Id as a personal identifier

Since the tax identification number is unique to a person, it is theoretically possible to compare all databases in which it is stored.

This way, all the information about the citizen's life would be accessible in one fell swoop.



eTIN (Electronic Transfer Identification Number)

What is eTIN?

eTIN stands for Electronic Transfer Identification Number. It is created using the employee's last name, first name, and date of birth.

German tax authorities introduced it for electronic tax returns via Elster.

But nowadays, eTIN is rarely used.

Earlier, employers needed eTIN to transmit employees' wage tax data to the tax office. But with the introduction of the tax identification number, employers no longer need an eTIN.

Moreover, section 41b of the Income Tax Act stipulates that an employer can use eTIN only if they do not have the tax identification number.


Tax Number (Steuernummer)

Tax number (Steuernummer in German)

What is a Tax Number?

Your local tax office (Local Finanzamt) issues the tax number (Steuernummer), which differs from your tax identification number.

It's a 10-13 digit number that indicates which tax office is responsible for you.

You can break down the German tax number into four parts.

  1. The first 2/3 digits identify your local tax office (Finanzamt)

  2. Next 2/3 digits identify your district

  3. Next 4/3 digits identify you

  4. The last digit is used as the check digit.
