The three taxing moments, in order
Moment 1 — the profit: corporate income tax, 19% to €200,000 and 25.8% above. Moment 2 — the salary: the director-shareholder pays box 1 on wages, with €58,000 as the customary-salary benchmark. Moment 3 — the distribution: box 2 on dividends, 24.5% up to €68,843 per person (fiscal partners €137,686 combined) and 31% above. Profit that stays in the company meets only moment 1 — and that is exactly where the design space sits: the holding mechanics.
The growth-phase design that saves €18,000–€20,000 a year
In a growth or startup phase, the customary salary can be agreed lower with the Dutch tax office, in writing — for several years at a time, keeping capital working inside the company. Combined with borrowing from your own BV up to €500,000 per person (the excessive-borrowing threshold; a main-residence loan sits outside it) for private spending, the effect lands: tax burden low now, settlement deferred, the money available where it compounds. In practice: around €18,000–€20,000 per year. Applying early in the year works best — the whole salary year then counts. One written design fixes the setup neatly: the founder-salary chapter and the full mechanics.
