Just shipped: visualizing a weird edge case in the German tax system
Germany taxes married couples jointly (“Ehegattensplitting”) —
but the real confusion is:
→ tax is calculated yearly
→ but incentives come from monthly payroll
So what people feel ≠ what they actually pay.
Built a small simulator to show this:

monthly net (III/V)
actual tax (≈ IV/IV with factor)
no-splitting scenario (I/I)
Target users:
→ expats
→ remote workers
→ people comparing real purchasing power
Curious if this kind of “perception vs reality” tooling resonates.
