Being self-employed I pay provisional tax to the IRD. I like to pay this through my bank's (ASB) website. But every time I go to make this payment they ask for "Tax period ended: 31 March" and offer a drop-down list of years (2011, 2012, 2013, etc). I always get confused as to which year to choose.
My tax year goes from 1st April to 31st March and I make three provisional ax payments per year. The next is due on 15th January.
How do I figure out which year to choose from the drop-down list? The reminder letter I get from the IRD doesn't really say (unless I'm just not understanding it correctly).
