If you start a side hustle in Germany (like publishing books or affiliate marketing) while working a full-time job, your health insurance provider ( e.g. AOK) will send you a form called “Pr\u00fcfung der Krankenversicherungspflicht”.<\/p>\n\n\n\n

\ud83d\udcc5 Real-Life App Timeline: What to Expect<\/h6>\n\n\n\n

They want to confirm that your regular job is still your main focus so you do not have to pay extra health insurance fees on your side income.<\/p>\n\n\n\n

Using the official Meine AOK App makes communication incredibly fast, but you need to know the workflow:<\/p>\n\n\n\n

Friday: I sent a message to AOK through the app’s text\/chat function and attached the 2nd page of the Business Registration (Gewerbeanmeldung).<\/p>\n\n\n\n

Monday (Today): AOK replied back through the app and I got a notification of a new message through email. Because a simple document upload isn’t enough for their legal check, they officially requested the full questionnaire form to be filled out.<\/p>\n\n\n\n

Here was the email notification I received prompting me to check the AOK App:<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

<\/p>\n\n\n\n

Monday (Same Day): I downloaded the form, filled out the required entries completely, attached all 4 necessary supporting documents directly through the app portal, and submitted everything in one message.<\/p>\n\n\n\n

Here was the message I sent them including the attachments:<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

<\/p>\n\n\n\n

Filling out their form is quite tricky. I find their one page questionnaire can be confusing if not read properly. Below are hepful tips on how to get started:<\/p>\n\n\n\n

how to answer the form properly<\/h5>\n\n\n\n
\ud83d\udccb Step 1: Your Primary Job Details (Angaben als Arbeitnehmer)<\/h6>\n\n\n\n

In this section, prove that your main job takes up most of your time and provides your main income.<\/p>\n\n\n\n

W\u00f6chentliche Arbeitszeit: Enter your official weekly contract hours (e.g., 38.5 or 40 hours).<\/p>\n\n\n\n

Durchschnittliches monatliches Bruttoarbeitsentgelt: Write your exact monthly gross salary (Gesamtbrutto) from your latest payslip.<\/p>\n\n\n\n

Zeitraum der Besch\u00e4ftigung: Enter your job’s start date. If your contract has no end date, write “unbefristet” (permanent) in the “bis” (until) field.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n
\ud83d\udcbc Step 2: Your Side-Hustle Details (Angaben zur Selbstst\u00e4ndigkeit)<\/h6>\n\n\n\n

Keep these numbers aligned with what you told the tax office (Finanzamt).<\/p>\n\n\n\n

Meine Angaben zur Selbstst\u00e4ndigkeit ab dem: The official start date of your business.<\/p>\n\n\n\n

Ich bin selbstst\u00e4ndig t\u00e4tig als: Your business title (e.g., “Buchautorin & Online-\/Affiliate-Marketing”).<\/p>\n\n\n\n

Durchschnittliches monatliches Einkommen: Your estimated monthly net profit (revenue minus expenses).<\/p>\n\n\n\n

Tip: If you gave the tax office a yearly estimate, divide that number by 12. If your yearly profit is \u20ac300, write \u20ac25.<\/p>\n\n\n\n

W\u00f6chentliche Arbeitszeit als Selbstst\u00e4ndiger: The hours you spend on your side hustle weekly. Keep this low (e.g., 5 or 10 hours). It must be significantly lower than your main job.<\/p>\n\n\n\n

Gewerbeum-\/abmeldung: If you registered a trade for marketing, check “ja, zum” and fill in your start date.<\/p>\n\n\n\n

<\/p>\n\n\n\n

\ud83d\udcce Step 3: The 4 Required Attachments<\/h6>\n\n\n\n

Do not send the form alone! When replying in the app, you must upload these four items together:<\/p>\n\n\n\n

The Completed Form<\/strong>: Signed and dated at the bottom.<\/p>\n\n\n\n

Here is a sample form:<\/p>\n\n\n\n

\"\"
Oplus_131072<\/figcaption><\/figure>\n\n\n\n

Your Payslip<\/strong>: A photocopy or digital PDF of a recent monthly payslip to prove your main income.<\/p>\n\n\n\n

Here’s a cropped copy of mine:<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

<\/p>\n\n\n\n

Your Business Registration<\/strong>: A copy of your official Gewerbeanmeldung (make sure to upload all pages!). Note: If the app says “Seiten werden zusammengef\u00fcgt”, don’t panic! It just means it is combining your pages into one clean document.<\/p>\n\n\n\n

Here was mine:<\/p>\n\n\n\n

and A Profit Explanation Note (Gewinnsch\u00e4tzung)<\/strong>: A short letter explaining your low starting numbers, since you don’t have an official tax paper (Steuerbescheid) yet.<\/p>\n\n\n\n

\ud83d\udcdd Free German Letter Template for the Profit Note<\/h6>\n\n\n\n

Copy, paste, and fill out this text on a blank page to upload as your official income estimate:<\/p>\n\n\n\n

Erkl\u00e4rung zur Gewinnsch\u00e4tzung f\u00fcr [Your Name]<\/p>\n\n\n\n

Sehr geehrte Damen und Herren,<\/p>\n\n\n\n

hiermit best\u00e4tige ich, dass ich beim Finanzamt f\u00fcr das Jahr der Betriebser\u00f6ffnung einen erwarteten Gewinn von [e.g., 150,- \u20ac] aus gewerblicher T\u00e4tigkeit und [e.g., 150,- \u20ac] aus selbstst\u00e4ndiger Arbeit angegeben habe. Dies entspricht einem kombinierten Jahresgewinn von insgesamt [e.g., 300,- \u20ac] bzw. einem durchschnittlichen monatlichen Einkommen von [e.g., 25,- \u20ac].<\/p>\n\n\n\n

F\u00fcr das Folgejahr wird ein kombinierter Gesamtgewinn von [e.g., 500,- \u20ac] erwartet.<\/p>\n\n\n\n

Mit freundlichen Gr\u00fc\u00dfen<\/p>\n\n\n\n

[Your Signature]<\/p>\n\n\n\n

\ud83d\udca1 The Golden Rule for Side-Hustlers<\/h6>\n\n\n\n

As long as your side hustle takes up less than 20 hours a week and your monthly profit stays under the legal social security threshold (around \u20ac603\/month), your side hustle remains 100% contribution-free (beitragsfrei). Your main job continues to pay for your full health insurance!<\/p>\n\n\n\n

<\/p>\n\n\n\n

\u26a0\ufe0f Why You Must Inform your Health Insurance Provider (The Risks of Staying Silent)<\/h6>\n\n\n\n

Some people think, “My side business makes almost no money, so I don’t need to tell my health insurance.” This is a massive mistake in Germany.<\/p>\n\n\n\n

Here is why keeping them informed protects you:<\/p>\n\n\n\n

The Tax Office Loophole: When you register your business via ELSTER, the tax office (Finanzamt) automatically shares data with other government bodies [\ud83d\udcc8]. Eventually, AOK will find out about your side hustle anyway.<\/p>\n\n\n\n

The Risk of Back-Payments (Beitragsnachzahlung): If AOK discovers your business months or years late, they will assume by default that you were working full-time on it. They can retroactively change your status to “primarily self-employed” and force you to pay thousands of Euros in back-premiums for the missing months.<\/p>\n\n\n\n

It Costs You Nothing to Be Honest: As long as your side hustle stays small, submitting this form changes absolutely nothing about your current insurance. Your monthly premium remains \u20ac0 extra, but your file is legally protected and compliant. It gives you 100% peace of mind.<\/p>\n\n\n\n

<\/p>\n\n\n\n

\ud83d\ude80 Conclusion: Compliance Drives Success<\/h6>\n\n\n\n

At the end of the day, keeping your health insurance company informed isn’t just about avoiding a bureaucratic headache\u2014it is about setting your business up for long-term growth. When your paperwork is 100% compliant, you eliminate financial stress, unexpected back-payments, and legal risks. Ensuring your legal foundation is secure gives you the ultimate peace of mind to focus entirely on what matters most: growing your audience, publishing your books, scaling your marketing channels, and watching your side business progress safely into a thriving success.<\/p>\n\n\n\n
