In ECLI:NL:RBGEL:2026:5889, Rechtspraak, the practical issue is a dispute where records, valuation and business facts had to carry the explanation. For founders, the useful question is whether the records can explain the facts, figures, assumptions and decisions when the story is tested.
A former director closes a company, absorbs the loss and moves on. Years later, an old box 2 loss offers tax relief. The decision appears personal and contained.
Then a letter arrives for the lower-earning partner. It concerns money the household has received, and perhaps already used for care costs, repairs or ordinary bills.
Belastingdienst rules create this tension when a substantial-interest loss becomes a tax credit and one partner still qualifies for payment of the general tax credit. The issue is limited, but it matters to a generation now selling businesses, unwinding holding companies and settling old exits.
One household, two assessments
Since 2023, payment of the general tax credit to a lower-earning fiscal partner has ended for people born after 1962. It remains available to qualifying partners born before 1963.
That boundary matters. This is not a general issue for couples with unequal incomes. It sits mainly in older households, including former owner-managers whose company history still shapes their personal tax position.
A box 2 loss can remain after shares are sold, a company is liquidated or a substantial interest otherwise ends. Under statutory conditions, the taxpayer may later convert the unrelieved loss into a tax credit.
For 2026, the Belastingdienst publishes a conversion percentage of 24.50%. The rate for earlier years may differ. The resulting credit reduces income tax and national-insurance contributions in box 1.
That relief can also shrink the tax capacity supporting payment of the lower-earning partner's general tax credit. One partner's tax benefit may therefore reduce the other partner's expected payment.
Imagine a retired founder and a spouse with little taxable income. A partner-related refund reaches their bank account in spring. They spend it on home repairs and care costs.
During summer, the founder's assessment falls after the old box 2 loss is converted. The household gains relief in one assessment, while the basis for the earlier refund changes in the other.
The real risk is timing
I read this less as a difficult calculation than as a problem of false finality. An assessment arrives, money is paid and the household treats the matter as complete.
Yet the connected assessment of the other fiscal partner may still move. The letters travel separately, while their financial logic remains linked.
For a qualifying lower-earning partner born before 1963, the maximum published payment in 2026 is €3,115. The actual amount depends partly on how much Dutch tax the other partner pays.
When that tax falls, the partner payment can fall with it. A repayment may follow.
The converted loss itself has conditions. The loss must first be established in an irrevocable income-tax assessment. Both fiscal partners must have had no substantial interest in the year for which the credit is granted and in the preceding year.
The Belastingdienst establishes the credit through a decision open to objection. Within the applicable time limit, it can also reduce an earlier final assessment to process a qualifying credit.
What the household ledger should show
For many founders, the old box 2 loss remains part of the former company story. It belongs to the sale, liquidation or failed investment. The partner refund belongs to private life.
That separation is understandable, but it can distort the view of household cash. A useful overview puts both partners' assessments on one timeline.
It records when the box 2 loss became final, when conversion was requested, which year received the credit, when each assessment arrived and what cash was paid. This need not become elaborate administration.
A clear chronology often exposes the dependency. It distinguishes cash received from cash that the household can reasonably regard as settled.
Where a loss-conversion decision or connected assessment is still moving, a partner-related refund deserves restraint. Its durability may depend on another calculation that has not yet finished.
Tax liability and payment capacity
There is another distinction worth keeping clear. A dispute about the amount of tax belongs to the assessment process. Difficulty paying an established amount belongs to collection.
Belastingdienst arrangements for qualifying individual income-tax debts can include a standard route of up to 12 months. Other arrangements depend on payment capacity and personal circumstances, while collection interest may apply.
The payment question follows its own route. It does not change the underlying calculation, but it can decide whether a household regains control of its cash flow.
The former director and spouse face one household question, even though the tax system sends two individual assessments. Did the converted loss create genuine net relief, or did it partly move cash from one partner's assessment to the other?
The answer lies in the combined result, not in the most welcome letter.
An old company loss is not inherently a problem. It may provide legitimate and valuable relief. The discipline is to follow that relief through the household before treating the money as final.
In tax, as in a ledger, timing can change the meaning of a perfectly correct entry.
