S&O deduction (WBSO)

When you can use the WBSO deduction and how NettoWise handles it.

The R&D deduction (WBSO) is an entrepreneur deduction for entrepreneurs who carry out recognized R&D. This deduction lowers your taxable profit and therefore your taxable income in box 1.

The WBSO deduction lowers your taxable income in box 1, which makes your tax calculation lower.

When you can use this deduction

You can use this deduction if you are an entrepreneur and have a valid WBSO statement for the tax year. Eligibility depends on your personal situation and the scheme conditions.

Where to configure it

You set this per tax year in your entrepreneur deductions.

How NettoWise handles it

NettoWise spreads the WBSO deduction evenly across the year. You see part of the deduction applied every month.

If the deduction has already been applied and you later find out you were not eligible, the amount already applied is spread back over the remaining months. You will then see a negative amount in those months.

Example: spread across 6 months

Assume your annual deduction is € 6,000 and you look at the first 6 months. NettoWise spreads it evenly.

Deduction	€ 1,000	€ 1,000	€ 1,000	€ 1,000	€ 1,000	€ 1,000	€ 6,000
Profit after deduction	€ 9,000	€ 9,000	€ 9,000	€ 9,000	€ 9,000	€ 9,000	€ 54,000

Example: correction if you are not eligible

Assume the deduction was applied for 3 months and you then discover you are not eligible. The amount already applied is spread back over the remaining months.

Deduction (correction)	€ 1,000	€ 1,000	€ 1,000	-€ 1,000	-€ 1,000	-€ 1,000	€ 0
Profit after deduction	€ 9,000	€ 9,000	€ 9,000	€ 11,000	€ 11,000	€ 11,000	€ 60,000

Where the deduction sits in the calculation

The WBSO 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.
