Division of Partners' Income for Leiden Residents
For residents of Leiden, division of partners' income is a smart tax tool under Dutch tax and family law. Spouses or fiscal partners can reallocate income from work, home ownership, and savings to pay less tax. You arrange this through your income tax return, depending on your partnership and marital property regime. In this article for Leiden residents, we explain the rules, with local tips and examples.
What is division of partners' income?
This arrangement allows fiscal partners to allocate incomes for income tax (IB) purposes, particularly in box 1 (work and home) and box 3 (assets). This maximizes tax credits and spreads tax brackets for lower taxes. See our article on marriage and taxes. In Leiden, with many dual-income households in academia, this is especially advantageous.
Married couples or registered partners automatically qualify as fiscal partners. Cohabiting partners must meet strict requirements. Without division, incomes remain separate, which is more expensive.
Legal basis
The Income Tax Act 2001 provides the foundation:
- Article 2.1 Income Tax Act 2001: Definition of fiscal partners.
- Articles 2.13 and 2.14: Division of box 1 incomes.
- Article 2.36: Division of deductions.
- Article 3.111: Box 3 savings and investment accounts.
Overview of division mechanisms
Choose the best mechanism for your situation. Here's a table for Leiden residents:

| Box 1 division | Divide work/home incomes 50/50 or custom. | Both have income. | Optimize brackets and credits. |
| Attribution of payments | Allocate alimony to ex-partner. | Periodic for maintenance. | Deductible for payer, taxable for recipient. |
| Division of gifts | Split gifts for tax purposes. | No exclusive conditions. | Lower gift tax. |
| Box 3 division | Reallocate assets as of January 1. | Fiscal partnership. | Lower tax on imbalances. |

Practical examples for Leiden
Example 1: Box 1 in Leiden
Partner A (€60,000 from UM employment) and B (€20,000). Without division, A hits higher bracket (37.07% vs. 36.93% in 2023). 50/50 division saves €500, plus tax credit for B.
Example 2: Alimony post-divorce
€12,000 alimony: deductible for payer, taxable for recipient. Essential for Leiden divorces.
Example 3: Box 3
A €200,000 savings, B €0. Division halves the tax (approx. 1.2% notional).
