Taxes & Public Charges, a guide that works out when and how much you pay or get back, from property holding tax to year-end refunds and health insurance contributions

With tax, the room to choose only becomes visible once you know when and on what basis the amount is fixed. Here we follow the money you pay and the money you get back as a single thread.

We cover the assessment date and published price behind property holding tax and property tax, the point at which the single-household exemption beats per-person assessment, the deadlines for year-end settlement and correction claims, how health insurance contributions are calculated from income and assets, and who qualifies for utility bill reductions and how to apply.

The same asset produces a different bill depending on whose name it is in and when it is filed. We put numbers on the points where a condition or a date becomes an amount, without deciding for you which option is better in your case. Proposed reforms are kept separate from enacted law, and final confirmation belongs with the tax office and the responsible agency.
