Excel formula in German to calculate German income tax

Please write an excel formula, that calculates the German income tax.
Please send one formula for each year.
I need 2018-2027.
Each year is different
Formula needs to 100% match the results shown in the German govermental website for this matter:

You need to check the "single" lower selection for calculation.

I tried the formula, that was posted in here


https://www.datev-community.de/t5/Wirtschaftsberatung/Excel-Formel-zur-exakten-Berechnung-der-tariflichen/td-p/133285#_=_

But it is not specific enough, or did not work for me.

I assume these links might be helpful, or not. You need to check if the formulas are correct. Maybe even research.

Thank you!
