Box 3 reference date becomes January 1

You are liable for 1.2% investment yield tax on any gains you make from savings and investments. Up until recently this tax liability was taken from the average of your assets and liabilities on 1 January and 31 December of the particular tax year. However this has changed and you should be well aware of this, especially if you just hover around the tax-free allowance threshold. As from 2011 there is only one reference date, namely 1 January. If the balance of your assets and liabilities at that moment is more than the tax-free allowance, then you must declare this in box 3 of your income tax return. The Supreme Court has also recently ruled that you must declare your share in any maintenance reserve from a Society of Homeowners (Vereniging van Eigenaren) as an asset in box 3.
