I have question on taxation and choosing tax classes. It is already complicated enough and now figure out tax classes for couples seem crazy.
Is there a proper tool to check for appropriate tax class for couples? We both earn have a difference of about 15% in annual salary right now. Some calculators show 4/4 is better while other show 3/5. Right now I am leaning towards 4/4.
Also is it possible to change the tax classes multiple times in middle of the year? I might change my job later this year and would then change the salary difference and hence might need new calculation.
Is there proper tool to do these checks or we have to hire accountant for it?
Thanks a lot!
