Box 3 or a BV holding for your investments?
Compares your net worth after tax under box 3 versus a BV holding, using 2026 rates.
The capital
Market value today, whether held privately (box 3) or contributed into a holding BV.
Sets which box 3 flat-rate return applies: 1.28% for cash, 6.00% for securities and property (2026 rates).
Total return before tax and financing costs. Box 3 tax uses the flat rate above regardless of this figure.
Since the Hoge Raad's Kerstarrest, actual return can replace the flat rate if lower and substantiated. Turn on if your return above is below the flat rate.
10.4% non-residential, 8% residential not owner-occupied (2026). One-off cost when contributing the property into the BV.
Financing
A BV deducts the actual interest paid. Box 3 only ever deducts the flat-rate debt percentage (2.70% in 2026).
The BV route
Horizon & income need
€0 leaves the return to compound. Usually the biggest driver: a BV taxes a payout twice (Vpb + box 2); box 3 doesn't tax withdrawals.
"Keeps running" isn't like-for-like: the money stays locked in and still carries latent box 2 tax later. Both figures are shown below.
Doubles the box 3 tax-free allowance and the box 2 low-rate bracket.
E.g. dividend from an operating BV. The low box 2 bracket is shared across everything you take in a year.
Future rules preview
Passed the Tweede Kamer (12 Feb 2026) but isn't law: it's before the Eerste Kamer and the Minister has said the bill would likely be rejected as-is. A directional preview, not a forecast.
Result
Things to consider
- →Modelling assumption. Assumes a constant annual return and fixed debt, reinvested at the same rate — a single scenario, not a forecast.
- →The withdrawal need is usually decisive. More spending each year favours box 3; profit staying longer inside the BV favours the BV.
- →No business succession relief (BOR). The BOR doesn't apply to passive investment capital — don't rely on it for succession planning here.
- →Real-return box 3 is coming, timing is not settled. The Wet werkelijk rendement box 3 passed the Tweede Kamer (12 Feb 2026) but isn't law: the Eerste Kamer may reject or delay it.
- →What the "future rules preview" assumes. 36% tax, €1,800 tax-free result/person, actual-return taxation on cash and securities, rental income taxed yearly with growth taxed at sale.
- →Interest deduction limits in the BV. Earnings-stripping and reduced exemptions can cap deductibility at high leverage — not modelled here.
- →Excessive borrowing from your own BV. Loans over roughly €500,000 taken back from the BV are treated as a deemed dividend.
- →Losses in the BV. A loss year shows zero corporate tax; carry-forward and carry-back aren't modelled.
- →Liquidation is a choice, not a default. Choose "Keeps running" to see book value with no exit tax yet applied — useful beyond this horizon, though latent box 2 tax remains.
- →Not purely a tax question. Liability protection, mortgage treatment, and BV admin burden matter too and aren't captured here.
- →Rates used (2026). Box 3: 36% tax, 6.00%/1.28% flat return, €59,357/€118,714 allowance. Vpb: 19%/25.8%. Box 2: 24.5%/31%. Transfer tax: 10.4%/8%.
