Starter deduction
The starter deduction is an extra entrepreneur deduction for starting entrepreneurs. Like the self-employed deduction, it reduces your taxable profit and therefore your taxable income in box 1.
When you can use this deduction
You can use the starter deduction if you are a starting entrepreneur and meet the conditions, including the hours criterion. Eligibility depends on your personal situation and the tax year.
Where to configure it
You set this per tax year in your entrepreneur deductions.

How NettoWise handles it
NettoWise spreads the starter deduction evenly across the year. A portion is included in your calculation each month.
Example: spread across 6 months
Assume your annual deduction is € 6,000 and you look at the first 6 months. NettoWise spreads it evenly.

Where the deduction sits in the calculation
The starter deduction is applied after your profit and before the SME profit exemption. That lowers your taxable income in box 1 and reduces the final tax calculation.
