In Leiden, where the rental market is under pressure due to the university and many young tenants, an income-dependent rent increase is calculated based on your joint rental income, as determined by the Tax Authorities. Landlords in Leiden use income data from two years prior (e.g., 2022 for an increase in 2024). The formula is: maximum increase = rent price × (income-dependent percentage × income index). For 2024, in Leiden's free sector, 5.3% applies for income above €47,699, with lower percentages for lower incomes. Note the local rent price threshold of €808.06 for the free sector.
Step 1: Request your income statement via Mijn Belastingdienst. Step 2: Check if your property in Leiden falls under the scheme, especially in popular neighborhoods such as the city center or Professorenwijk. Step 3: Compare the proposed increase with the statutory maxima; if exceeded, you can file an objection with the Huurcommissie in Utrecht, which handles many Leiden rent disputes. Only net rent increase counts, excluding service charges. Landlords must submit the proposal before 1 May. In case of declining income due to, for example, job loss in the Leiden academic sector, you can apply for remission via the municipality. The municipality of Leiden also offers free advice via the Woonloket for tenants in financial distress. This scheme protects middle incomes in Leiden, but be alert to errors in income data, especially for expats or student houses.
