The situation

  • Single, salary €85,000 a year, 30% ruling, no home in the Netherlands.
  • Savings €30,000; shares and funds €40,000.
  • A flat in Pune worth €100,000, fully owned.

30% ruling, tax-free
− €25,500

€59,500

Box 3: savings, investments and the flat

The flat counts as an investment in Box 3, so Box 3 wealth is €30,000 savings plus €140,000 other assets. Before treaty relief, Box 3 tax is €2,058.

Under the Netherlands–India treaty, the share of Box 3 tax that falls on the flat is exempt. That relief is €1,406, leaving €652 of Box 3 tax.

Total

Box 1
€16,020
Box 3 after relief
€652
Total income tax 2026
€16,672
Without claiming treaty relief
€18,078

Forgetting the treaty relief would cost this engineer €1,406 a year. See the India page and enter your own figures in the full calculator.
