How to Change Tax Class on ELSTER: A Simple Step-by-Step Guide

Changing your tax class in Germany is an important step for optimizing your income tax deductions, especially for married couples. If you’re doing this for the first time, it might seem complicated, but it’s actually quite straightforward.

This guide will walk you through the process, step by step, and highlight key things to consider before making any changes.

What is a Tax Class (Steuerklasse) and Why Does it Matter?

In Germany, your tax class determines how much tax is deducted from your salary each month. The tax class you fall into depends on factors like your marital status, whether you have children, and how much you earn.

Tax Class I: For single individuals or those who are separated or divorced.
Tax Class II: For single parents who live alone with children.
Tax Class III: Typically for married couples where one partner earns significantly more than the other.
Tax Class IV: For married couples with similar income levels.
Tax Class V: For married couples where one partner earns significantly less than the other.
Tax Class VI: For individuals with multiple jobs.

Before Changing Your Tax Class: What to Consider

Before you start the process of changing your tax class, it’s important to understand a few things:

Who Can Change Their Tax Class?
- Married couples can change their tax class, especially if their income levels differ significantly.
- You can only change your tax class once a year unless there’s a major life event, like a change in marital status or a significant change in income.
Choosing the Right Tax Class Combination
- Tax Class III and V: This combination is ideal for married couples where one partner earns significantly more than the other. The higher earner will be in Class III (lower tax rate), and the lower earner will be in Class V (higher tax rate).
- Tax Class IV and IV: This combination works well for couples with similar incomes, as it balances the tax deductions equally between both partners.
What Happens If You Choose the Wrong Tax Class?
- If you select the wrong tax class combination, you might end up paying too much or too little tax throughout the year. This could result in a large tax bill when you file your annual return, or it could lead to underpayment, which may cause penalties.
- If you’re unsure which tax class is best for you, it’s worth consulting a tax advisor before making any changes.
How Often Can You Change Your Tax Class?
- You can change your tax class once a year or after a significant life event, like getting married, having a child, or if you experience a change in income.
Impact on Take-Home Pay
- Changing your tax class can impact your monthly net income. For example, switching to tax class III might mean higher take-home pay for the higher-earning spouse, but a higher tax deduction for the lower-earning spouse if they’re in tax class V.

Step 2: Find the Right Form

Once logged in, look for the section titled “Formulare” (Forms).
Find and select “Antrag auf Steuerklassenwechsel” (Application for a Change of Tax Class). This is the form you need to request a tax class change.

Step 3: Fill Out the Form You’ll be asked to provide several pieces of information, including:

Personal Information: Your name, address, and tax identification number (Steuer-ID).
Marital Status: Indicate whether you are married, single, or divorced.
Your Spouse’s Information: If you’re married, you’ll need your spouse’s details, including their tax class. If your spouse is in tax class V, you may want to select tax class III for the higher earner to benefit from the more favorable tax class combination.
Reason for Change: You’ll be asked why you want to change your tax class (e.g., marriage, divorce, significant change in income).

Step 4: Submit the Form

After you’ve completed the form, double-check all the information for accuracy.
Click “Absenden” (Submit) to send the application. ELSTER will electronically process your request.

Step 5: Wait for Confirmation

The tax office will process your request and may take several weeks to confirm the change. Once your request is approved, you will receive a confirmation letter in the mail.

Step 6: Inform Your Employer

Once you’ve received the confirmation, you need to notify your employer about the change in your tax class. They will adjust your tax deductions according to the new tax class, so your monthly take-home pay will reflect the change.

Step 7: Monitor Your Pay Slip

After the tax class change has been implemented, check your pay slip (Lohnabrechnung) to make sure the correct tax deductions are being applied. If there’s an issue, contact your employer or tax office for clarification.

What to Do if There’s a Mistake or Delay?

If you make a mistake when filling out the form or if the tax office takes too long to process the change, here’s what you can do:

Mistakes on the Form: If you realize you made an error on your form after submission, you can usually correct it by contacting the tax office (Finanzamt) directly. If the mistake is minor, they may make the change for you.
Processing Delays: If it’s taking longer than expected to receive confirmation, you can reach out to your local tax office for an update.

Additional Tips for Married Couples

Tax Class III and V Combination: If one partner earns a lot more than the other, the higher earner should be placed in Tax Class III and the lower earner in Tax Class V. This combination is often beneficial because the higher-earning spouse will pay less tax, and the couple as a whole will benefit from a lower total tax burden.
Tax Class IV and IV Combination: If both partners earn similar incomes, the IV/IV combination may be ideal. This option ensures that both partners pay taxes equally and is often the most straightforward choice.
Life Changes: Be sure to update your tax class if there are any significant life changes (e.g., birth of a child, divorce, significant income shift), as this could affect your overall tax obligations.
