Church tax is the surprise for many people in Germany. It applies if you're registered as a member of certain churches. Some colleagues ticked a box on the registration form without realising what it meant. Check what you declared at registration, because it follows you onto the payslip.
First full month in the new job in Sweden and I've just spent an evening with the payslip and a translation app. The gross salary matches the contract. The net is a lot lower than the calculator I used before accepting the offer.
Some of it I understand: income tax, obviously. But there's a municipal part that's higher than I'd guessed, and a union fee I apparently agreed to on my first day while signing twenty other things. There's also a line I still can't identify.
Did your first payslip surprise you? Which deductions did nobody explain, and is there anything I should check now rather than in a year?
