This spreadsheet computes taxation rates for different locations, for different salaries.
Currently included are:
- US / California
- Australia
- UK (old data)
- Sweden (old data)
Computed rates include income taxes, major tax rebates, local taxes (where applicable), retirement tax rebates. In the US it also includes Social Security as a tax (since it's unlike that it's anything but that to anyone under 50 now).
Rates are compared across countries using Purchasing Power Parities.
Note that I created this spreadsheet a while back, and only quickly updated it recently. Therefore, take all figures with a grain of salt, and verify them for yourselves. Suggestions and updates gratefully accepted.
