5. Tax return: Do I have to declare my income?

If you regularly earn income as a bottle and can collector, you should definitely file a tax return . Even though there is a tax-free allowance , which will be slightly adjusted due to the increase in the basic tax-free allowance in 2025, you will be required to report your income as soon as this allowance is exceeded.
To avoid problems with the tax office, it’s important to accurately document all income and expenses related to collecting returnable bottles. However, ensuring your income remains below the tax-free allowance might allow you to forgo filing a tax return altogether. This way, you’ll always keep track of your tax obligations and avoid unpleasant surprises.
6. What happens if the tax liability is exceeded?

Anyone exceeding the tax-free allowance must expect the usual consequences associated with taxable income. This means that the excess income must be taxed, and taxes may become due and must be paid retroactively. Bottle collectors who regularly earn high incomes from collecting returnable bottles should therefore keep a close eye on their earnings and, if necessary, seek advice from a tax advisor to avoid unpleasant additional payments .
It is important to review your income early on and take precautions if necessary to avoid unintentionally falling into a tax trap . Caution and transparency are crucial here.
