Quick Start

Here's an example of how to calculate income tax using OpenFisk, using the income tax model for the Netherlands:

import numpy as np
from openfisk.nl.income import calculate_income_tax

# Example incomes to calculate tax for
taxable_incomes = np.array([10000, 30000, 50000])
# Define tax bands (lower bounds) for the progressive tax system
tax_bands = np.array([0, 20000, 40000, np.inf])
# Define the tax rates for the respective bands
tax_rates =  np.array([0.1, 0.2, 0.3])

# Calculate the income tax for each income in taxable_incomes
taxes_due = calculate_income_tax(taxable_incomes, tax_bands, tax_rates)

# Output the tax due for each income level
print(taxes_due)
