I found this on PPJN Country multipliers (applicable to base§or pay) in force to balance different tax rates and/or cost of living: UK: 1.5 Romania: 1.45 Macedonia: 1.3 Austria: 1.25 Latvia: 1.2 Georgia, Moldova: 1.1 Poland: 1.05 Other countries and all service providers: 1.0 Bulgaria (only applied to variable elements): 0.9
Am I correct when I think that you take you monthly salary lets say 2.800 EUR times 1.5 for UK base? As an example
