Fifth rule and tax rate
Dear Sir or Madam,
I have agreed with my previous employer to terminate my employment at the end of January with a severance payment. Unfortunately, I am currently having a difficult discussion with the tax advisor of my former company regarding the tax to be assessed.
Specifically for tax class I and church tax obligation:
My annual salary in 2010 was 72,000 euros. I left at the end of January, so my taxable income for 2011 is 6,000 euros. In addition, a severance payment of 100,000 euros was agreed upon. This should result in a clustering of income and the application of the "fifth rule". According to my research and calculations (e.g. http://www.sueddeutsche.de/app/jobkarriere/abfindungsrechner/), this would result in a tax burden of approximately 22,000 euros (income tax, solidarity surcharge, church tax).
However, the tax advisor of my former employer, using DATEV calculations, comes to a significantly higher tax burden of almost 40,000 euros. Apparently, DATEV assumes a fictitious income based on the previous year and then applies the "fifth rule". However, I do not plan to work this year.
Could you please explain to me which calculation is correct?
Kind regards,
