30% ruling - tax-free and taxable income do not equal total gross

[eualexam]

Hello,

I'm having some trouble understanding the calculations, they don't seem to match the results I'm getting while doing a manual calculation.

Filters on: holiday allowance included and 30% ruling.

Amount tested: 80k gross per year.

Main results that don't match: taxable income, tax-free income, and implicitly, the final net salary.

Questions & comments based on manual calculation in the screenshot attached.

Thanks!

@eualexam thank you for adding your feedback! it will be be more convenient for others if you put in text (not image) all your calculations - that other can check by coping specific numbers
