The Dutch box 3 counter-evidence route tests the actual return on a taxpayer’s full private asset position. The tax-free allowance reduces the tax base under the deemed-return method. It does not reduce the actual return under review. That difference can determine whether a reduction is available.
Why this matters
Low interest on one savings account is not enough for a lower box 3 assessment. The test covers all box 3 assets and debts for that calendar year. Interest, dividends, rent, and value changes can count. For 2023, the allowance was €57,000 per person and €114,000 for fiscal partners. It affected the deemed-return calculation. Interest on the full savings balance still counts. A negative total actual return is set to zero and cannot be carried forward.
Example
A founder held private savings, securities, and crypto during 2023. The savings account paid little interest, and part of its balance fell within the tax-free allowance. The founder must include the securities gain and crypto value movement in the annual return. A gain on those holdings may outweigh the low savings interest. The file needs bank statements, investment and crypto records, valuations, debt records, and ownership details. These records support a comparison with the deemed return in the assessment.
XTROVERSO tips
- Start with the assessment. Retrieve the income tax return and final assessment for the relevant year. Note the deemed box 3 return used in the assessment.
- List the full private position. Include every savings account, investment, second home, crypto holding, private receivable, and box 3 debt held during the year.
- Build the evidence file. Collect annual statements, interest and dividend records, valuations, transaction files, debt documents, and ownership records.
- Separate business and private cash. Keep company cash out of the private box 3 file. For a sole proprietor, record why cash is needed for VAT, payroll, tax, suppliers, equipment, or contracts.
- Do not count on a refund yet. Treat a possible reduction as an uncertain tax position. Processing may take years, so do not include an expected refund in spending or investment plans.
