ELStAM (electronic wage tax deduction characteristics)

How employers in Germany retrieve wage tax deduction characteristics, why inbound assignees start on tax class VI and what a wrong employer registration costs.

1. What is ELStAM (electronic wage tax deduction characteristics)?

ELStAM stands for *Elektronische LohnSteuerAbzugsMerkmale* – electronic wage tax deduction characteristics. It is the database held at the Federal Central Tax Office from which employers retrieve the characteristics governing wage tax withholding for an employee: tax class, factor, number of child allowances, church tax marker and any allowances registered with the tax office. The legal basis is Section 39e EStG.

The procedure replaced the former paper wage tax card. The decisive difference is not the medium but the direction. Formerly the employee presented a document; today the employer retrieves the data itself – and remains responsible for withholding correctly.

Retrieval requires two items: the employee's tax identification number and date of birth. Both come from the employee. Without them, no retrieval is possible.

For international groups this is where the first problem sits. An assignee arriving from abroad does not yet have a German tax identification number – and without it, German law requires withholding at the least favourable tax class from day one.

2. Origin and development

Until the changeover the wage tax card was a paper document issued by the municipality and handed to the employer by the employee. If someone changed jobs the card moved with them; if it was lost, only a replacement certificate helped. Changes – marriage, a child, leaving the church – had to be entered by hand.

Moving to ELStAM shifted the data to the Federal Central Tax Office and turned it into a retrieval procedure. The media break disappeared, but a new one appeared: the data are correct only where the registration authority, the tax office and the employer hold the same picture. An unreported change of address, or a change list that was never retrieved, now feeds straight into the withholding.

For payroll that is a shift in responsibility. The employer no longer files what is handed over – it retrieves, checks and applies. Groups used to jurisdictions where the employee submits a withholding declaration to the employer find this counter-intuitive: in Germany no such form reaches you, and asking for one delays the retrieval you are obliged to make.

3. Core principles and how it works

Retrieval needs the tax ID and date of birth

Both come from the employee. Missing or wrong, and the retrieval fails – leaving the employer with the fallback rule.

Registration as primary or secondary employer

On retrieval the employer states whether this is the first employment. Only one employer can be the primary one; every further employer receives tax class VI. If a second employer wrongly registers as primary, the first loses its entitlement – a common and painful error, and one that happens readily within a group where someone holds roles at two entities.

Change lists are retrieved, not awaited

The Federal Central Tax Office makes changes available for retrieval. The employer must collect and apply them monthly. Skip it and you withhold on outdated characteristics – and are liable for it.

Tax class VI as the fallback

Where no characteristics are available – because details are missing or the employee has blocked retrieval – Section 39c EStG requires withholding at tax class VI. This is not a penalty but the safeguard; it is corrected in the employee's own assessment.

Deregistration belongs to the exit

When employment ends, the employer deregisters the employee in the procedure. Omit it and you block the next employer as an apparently continuing primary employer.

4. Who is ELStAM (electronic wage tax deduction characteristics) relevant for?

- All employers in Germany – the procedure is mandatory for wage tax withholding, without exception by size or sector. - Payroll teams – registration, deregistration, change lists and error handling sit with them. - Inbound assignees and new arrivals – without a German tax identification number the employment begins on tax class VI. - Employees with more than one employment – correct primary/secondary allocation decides their monthly net. - HR departments – they capture the details at onboarding and trigger the deregistration at exit.

5. How it differs from related terms

- ELStAM and the annual certificate – ELStAM supplies the characteristics *before* payroll; the annual certificate reports the result *after* the year. - ELStAM and the payroll tax return – the return declares the tax withheld to the tax office; ELStAM determines how much is withheld. - Tax class and child allowance – both sit in the ELStAM but work differently. The tax class affects wage tax; in withholding, the child allowance affects only the solidarity surcharge and church tax. - ELStAM and a registered allowance – an allowance applied for at the tax office is transmitted as a separate characteristic. It is not part of the tax class.

6. Variants and adaptations

The main departures from the standard case:

- Employees with limited tax liability – they generally have no ELStAM. Withholding follows a certificate issued by the tax office for the place of business under Section 39(3) EStG. This is the route for many inbound assignments. - Blocked retrieval – employees can block retrieval at the tax office or restrict it to named employers. The consequence is withholding at tax class VI. - Factor procedure – married couples may choose a factor procedure instead of the III/V combination; the factor is transmitted as its own characteristic. - Short-term and marginal employment – flat-rate taxation is often the alternative here, in which case no ELStAM are retrieved.

7. Advantages and challenges

Advantages

  • No paper, no media break, no risk of loss when changing employer
  • Changes take effect promptly instead of waiting for a handwritten entry
  • The employer receives exactly the characteristics it needs for withholding – no more
  • Multiple employments become visible in the procedure and are therefore taxed correctly
  • Holding the data in one place prevents contradictory characteristics across employers

Challenges

  • Without the tax identification number the employment begins on tax class VI
  • A wrong registration as primary employer strips the existing employer of its characteristics
  • Change lists must be actively retrieved – a forgotten retrieval keeps withholding wrongly and silently
  • Omitted deregistrations block the next employer
  • Employees cannot see directly which characteristics reached their employer

8. Best practices for implementation

Make the tax identification number a condition of onboarding

Without it no retrieval is possible. Asking for it only with the first payroll run produces a payroll at tax class VI and a correction afterwards. For inbound assignees, applying for the number belongs in the relocation checklist, not in payroll.

Make the change list part of the monthly run

The retrieval belongs at the start of the payroll run, not the end. Changes arriving after the run take effect only in the following month – and generate queries.

Tie deregistration to the exit process

Deregistration in the ELStAM procedure belongs on the same checklist as the reference and the employment certificate. Forgotten deregistrations surface only at the next employer.

Ask explicitly about further employment

Only the employee knows whether yours is the first employment. An express question on the onboarding form prevents the wrong registration – and in groups, ask specifically about roles at affiliated entities.

9. Tips for employers and employees

For employers

  • **Retrieve before the payroll run** – characteristics arriving later take effect only next month
  • **Mark primary or secondary correctly** – a wrong entry strips another employer of its characteristics
  • **Do not forget the deregistration** – otherwise you block the next employer
  • **Tax class VI is the fallback rule** – Section 39c EStG, not an employer discretion

For employees

  • **Supply your tax ID and date of birth immediately** – without them you are taxed at class VI
  • **Report changes to the tax office** – your employer cannot change tax class or allowances itself
  • **With two jobs, settle which employer is the primary one** – the allocation sets your monthly net
  • **Tax class VI is not final** – your assessment returns wage tax overpaid

10. Conclusion

ELStAM is a retrieval procedure, and that is the practical shift from the old wage tax card: the employer no longer waits for a document, it fetches the characteristics – and is answerable for applying the current ones.

Three points decide whether a run is clean. The tax identification number must be there at onboarding, otherwise the employment begins at tax class VI. The primary/secondary registration must be right, otherwise another employer loses its characteristics. And the change list must be retrieved monthly, otherwise the system keeps calculating quietly on stale data. None of the three surfaces immediately – they surface at a payroll tax audit.

For international groups, two of these carry extra weight. An inbound assignee has no German tax identification number on arrival, so the number must be applied for as part of relocation rather than discovered by payroll; for limited tax liability there is a separate route under Section 39(3) EStG. And a second role at an affiliated entity is exactly the case that breaks the primary-employer registration, because nobody experiences it as a second job.
