How and when to make prepayments in divergent financial years : companies which do not keep their financial year per calendar year

The tax authorities instruct when companies have to make their prepayments. For companies having their financial year per calendar year these dates are 10 April, 10 July, 10 October and 20 December. These dates can shift one or two days in case they fall on a Saturday, Sunday or holiday (this year 10 October falls on a Saturday, so the due date is shifted to 12 October). This article is about the companies which do not keep their financial year per calendar year.

This concerns companies which have an financial year of twelve months, but which doesn't run from 1 January until 31 December, but e.g. from 1 April until 31 March, or from 1 July until 30 June.

In case an financial year does not start on the first day of a month, this month is disregarded; if the financial year does not end on the last day of a month, this month is considerate as a full month. An financial year can e.g. run from 16 July 2014 until 15 July 2015 or from 23 April 2015 until 22 April 2016.

The payments should be made ultimately the tenth day of the fourth, seventh and tenth month, and the twentieth day of the last month of the financial year. In this case it also goes that when the due date falls on a Saturday, Sunday or holiday, the due date is shifted to the following working day.

Example 1
The financial year of NV X runs from 1 March 2015 until 29 February 2016. X should make prepayment at the latest on:

PP1: 10 June 2015;

PP2: 10 September 2015;

PP3: 10 December 2015;

PP4: 20 February 2016.

Example 2
The financial year of NV Y runs from 19 May 2015 until 18 May 2016. The financial year does not start on the first of the month, so May 2015 is disregarded. The financial year does ends on the last dat of the month, so May 2016 is fully taken into consideration.

NV Y should make prepayments on the following dates:

PP1: 10 September 2015;

PP2: 10 December 2015;

PP3: 10 March 2016;

PP4: 20 May 2016.
