Calculate your income in The Netherlands with and without a 30% ruling.
# To check if this is up-to-date with the tax rates go to
# http://www.expatax.nl/tax-rates-2016.php and see if there's anything
# newer there.
#
# I make no guarantees that any of this is correct. I calculated this
# at the time and have been updating it when new tax rates come along
# because people keep finding this useful.
#
# There's also an interactive JS version of this created by
# @stevermeister at
# https://github.com/stevermeister/dutch-tax-income-calculator
# although the two seem to show conflicting values and I have no idea
# which one is correct...

Thx, still quite accurate, though we can update it a bit for 2016.

@stevermeister/@avar: I compared these a while ago (early/mid-2016), and I noticed that when adding "General Tax Credit" and "Labour Tax Credit" to this calculator, the two outcomes only differed by about €1.

How income taxes is calculated?

Let's assume that taxable income is 37000

2017 Total rate is 36.55% up to € 19,982
and 40.80% for € 19,982 to € 67,072

Is the tax amount 37000 * 40.80 = 15.096 or (19982*36.55) + (37000-19982)*40.80 = 7303 + 6943 = 14.246?

and how is personal tax credit and Labour tax credit calculated?
