🚀 Minijobber einstellen: 7 steuerliche Vorteile für Unternehmen & was sich 2025 ändert

Many businesses rely on minijobbers (Minijobber) to respond flexibly to their workload. But hiring a minijobber comes with specific tax implications. Employers benefit from low contributions, but they also have to comply with statutory requirements.

In this article, you'll learn what tax advantages employing minijobbers offers, how registration works, and which mistakes you should absolutely avoid.

What is a minijob?

A minijob (Minijob) is a marginal form of employment (geringfügige Beschäftigung) in which the employee's monthly earnings may not exceed 520 euros. This type of employment is especially popular with small businesses, start-ups, and the service sector.

Characteristics of a minijob

• ✅ Monthly earnings threshold: 556 euros (New in 2025)
• ✅ Low social security contributions: the employer pays flat-rate amounts
• ✅ Tax-privileged: flat-rate tax (Pauschalsteuer) of just 2 %
• ✅ Registration required: minijobbers must be reported to the Minijob-Zentrale

Difference between a minijob and part-time work

A minijob must be distinguished from regular part-time positions. While the 556-euro threshold applies to a minijob, part-time workers are not subject to such a limit but are liable for regular social security and tax contributions.

Tax advantages of hiring a minijobber

Employing minijobbers brings tax and financial advantages for employers. This form of employment is a cost-effective way to bridge staffing shortfalls, especially for smaller businesses.

1. Low flat-rate tax of just 2 %

Employers pay a flat-rate tax (Pauschalsteuer) of just 2 % on the salary for minijobbers. This is significantly lower than the regular wage tax (Lohnsteuer) contributions for employment subject to social security.

2. Lower social security contributions

Whereas in regular employment relationships both the employer and the employee have to pay high social security contributions on the wage, in a minijob only the employer pays flat-rate social security contributions. The employee only has to pay into the pension insurance (Rentenversicherung), unless they opt out.

3. No additional costs for unemployment insurance

For minijobbers, businesses do not have to pay contributions to unemployment insurance (Arbeitslosenversicherung), which further reduces the ancillary wage costs.

4. Full cost control thanks to a fixed earnings threshold

Since 2025, the new earnings threshold for minijobbers has been 556 euros per month. For businesses, this increase means more room to maneuver in scheduling hours without losing the advantages of a minijob.

5. Simplified payroll & less bureaucracy

The registration and payroll of minijobbers is handled centrally through the Minijob-Zentrale. This eliminates the complex effort of regular payroll accounting.

6. Tax deductibility of wage costs

The wage costs for minijobbers can be claimed for tax purposes as a business expense (Betriebsausgabe). This way, businesses benefit twice — through low contributions and tax savings.

7. Flexible deployment options for businesses

Minijobbers can be deployed in many areas, e.g., for seasonal work, demand peaks, or supporting tasks. This lets the business respond flexibly without incurring high long-term wage costs.

Registering a minijobber – step-by-step guide

Before a business employs a minijobber, that person must be officially registered. Registration is handled centrally at the Minijob-Zentrale. A faulty or omitted registration process can lead to legal and tax consequences.

1. Registration with the Minijob-Zentrale

Employers must register every minijobber with the Minijob-Zentrale within six weeks of the start of work. This is done via the electronic reporting procedure using the company's employer number (Unternehmensnummer).

2. Stating the correct earnings threshold

Since 2025, the new earnings threshold of 556 euros has applied. Employers must ensure that this threshold is not exceeded, since otherwise the minijob is converted into employment subject to social security.

3. Information required for registration

The following information is required for registration:

• ✅ The minijobber's personal data
• ✅ Planned monthly remuneration
• ✅ Job description
• ✅ Pension insurance status (exemption possible)

4. Written employment contract

A written employment contract is not required by law, but it is strongly recommended, since it is the employer's responsibility to hand the minijobber a written record of the essential working conditions no later than one month after the start of work. The employment contract should contain the following:

• Name and address of the contracting parties
• Amount of the monthly remuneration (max: 556 EUR) and its due date, as well as the method of payment
• Working hours, rest breaks
• Job description
• Provision regarding pension insurance
• Start of the minijob and the end date
• Place of work
• Type of activity
• Duration of the probationary period
• Annual vacation entitlement

5. Social security contributions and remittance of the contributions

Employers pay flat-rate contributions for minijobbers to the Minijob-Zentrale:

• ✅ 2 % flat-rate tax
• ✅ 5 % health insurance (for those with statutory coverage)
• ✅ 15 % pension insurance

The employee can be exempted from the mandatory pension insurance, but must actively apply for this.

6. Regular review of the employment

Employers should regularly check whether the minijobber holds another marginal job in addition to the one at their company. If the total income from several minijobs exceeds the 556-euro threshold, the minijob becomes subject to insurance contributions.

Statutory requirements & obligations for employers

Anyone who hires a minijobber must comply with various statutory regulations. In addition to adhering to the earnings threshold of 556 euros, the documentation obligations and the correct remittance of social security contributions are especially important.

1. Adhering to the earnings threshold

Since January 2025, the maximum threshold for minijobs has been 556 euros per month. If this amount is exceeded, the minijob automatically becomes subject to social security.

💡 Tip: Make sure that special payments such as vacation or Christmas bonuses do not cause the threshold to be exceeded.

2. Documentation obligations

Employers must record their minijobbers' working hours precisely. Especially in heavily monitored industries (e.g., hospitality, retail), the tax office (Finanzamt) may request proof.

3. Social security contributions

Flat-rate social security contributions apply to minijobbers:

• ✅ 5 % health insurance (if the employee has statutory coverage)
• ✅ 15 % pension insurance (the employee can be exempted)

⚠️ Employers must remit these contributions monthly to the Minijob-Zentrale.

4. Checking for multiple employment

If the minijobber holds several jobs, the total income from all minijobs combined may not exceed 556 euros. Otherwise, the minijob rule no longer applies.

5. Minimum wage & working-hour limits

Minijobbers, too, are entitled to the statutory minimum wage (currently 12.41 euros per hour from 2025). Employers should ensure that the maximum working time is calculated correctly with the minimum wage taken into account.

🔎 Example calculation for 2025:

• ✅ 556 € / 12.41 € per hour = approx. 45 hours per month

6. Accident insurance

Minijobbers must be covered by accident insurance through the employer's professional association (Berufsgenossenschaft). The costs are borne by the employer.

Important: Common mistakes when employing minijobbers

Employing minijobbers is tax-attractive for businesses, but there are pitfalls that can lead to back payments or legal problems. Here are the most common mistakes and how you can avoid them.

1. Exceeding the 556-euro earnings threshold

Since January 2025, the new earnings threshold for minijobbers has been 556 euros. If this amount is exceeded, the minijobber loses their status and becomes subject to normal social security obligations.

💡 Tip: Make sure that special payments such as vacation or Christmas bonuses do not push earnings over the threshold.

2. Incorrect registration or late reporting

Minijobbers must be registered with the Minijob-Zentrale within six weeks of the start of work. A late or missing registration can lead to fines and back payments.

3. Missing documentation of working hours

Employers must document minijobbers' working hours precisely, especially in heavily monitored industries such as hospitality or retail.

4. Multiple minijobs without oversight

If an employee holds several minijobs and the total income rises above 556 euros, the minijob rule no longer applies. The employer must then pay normal social security contributions.

5. Disregarding the minimum wage

The statutory minimum wage applies to minijobbers as well. Since January 2025, it has been 12.41 euros per hour. Employers must ensure that the maximum working time is not exceeded.

6. Underestimating the accident insurance obligation

Minijobbers must be insured with the responsible professional association (Berufsgenossenschaft). Many businesses overlook this obligation, which can lead to high costs in the event of accidents.

Advantages of a minijob for employees & employers

Employing minijobbers brings not only tax advantages but also many practical benefits for businesses and employees. Here are the most important pluses for both sides.

Advantages for employers

1. Low personnel costs

Employers benefit from low contributions. The flat-rate social security contributions and the 2 % flat-rate tax make minijobbers a cost-efficient workforce.

2. Flexible staffing

Minijobbers can be deployed specifically for seasonal peak times, project work, or short-term shortfalls, without long-term wage obligations.

3. Less bureaucracy

Registration and payroll are handled through the Minijob-Zentrale, which keeps the administrative effort low.

4. No continued pay during illness or vacation

If the minijobber works on an hourly basis, there is no obligation to continue paying wages in case of illness or during vacation. This keeps the costs predictable.

Advantages for employees

5. Tax-free income opportunity

Minijobbers do not have to pay income tax (Einkommensteuer) if the employer covers the 2 % flat-rate tax.

6. Pension entitlements despite the minijob

Through the mandatory 15 % pension insurance, minijobbers accumulate pension entitlements. However, they can also be exempted from the contribution obligation.

7. Ideal for students, retirees & parents

Minijobs are ideal for people who want to work alongside their studies, retirement, or family without incurring tax disadvantages.
