On 3 November 2026, the State Secretary sent a Box 3 amendment to the Tweede Kamer. It would extend a capital-gains method to shares, bonds and options. The wider system is intended for 1 January 2028. Parliament has not finished the bill. For 2026, the assumed-return system remains in place.
Why this matters
Your bank app shows one balance. It cannot split your VAT pocket, tax reserve or software bill. Business money does not automatically become private Box 3 wealth. The facts and its use matter. The same applies in a VOF. A private broker account stays outside the partnership, even when business income funded it. Clear records help now and under possible future rules.
Example
A few client payments land after a busy month. Your bank app suggests you can send €15,000 to your private broker. First check your VAT pocket, income-tax reserve, insurance and next month’s late client. Your portfolio may be valuable, but it will not pay Friday’s bills unless you sell. Keep working cash and private capital apart.
XTROVERSO tips
- Give every euro a job. Split the balance into VAT, income tax, committed business costs and truly free private money. Use bank pockets or labels you understand at a glance.
- Keep your investment trail. Save opening and closing values, annual statements, interest, dividends, purchases and sales. Keep transaction costs visible too, even when they are generally not deductible.
- Name every transfer. Label transfers as drawings, private deposits, reimbursements or investment payments when they happen. Skip the year-end detective work.
- Keep VOF and private separate. Record shared cash and each partner’s capital account in the VOF books. Keep each partner’s private Box 3 file outside the partnership administration.
- Do not trade on pending rules. Keep the 2028 proposal on your watchlist. Do not rush a sale or account transfer while Parliament is still working on the legislation.
