IRD Tax Calc
Read full descriptionHide full description
A simple tax calculator. Now includes a tax refund calculator. If you have been offered a new job, been given a yearly rate and want to calculate what will end up in your pocket then this app is for you. Also, maybe you know what you get paid each fortnight but need to calculate your yearly gross income, then again, this app is for you. It doesn't take into account the 100 or so questions a tax advisor would ask, but gives a basic PAYG assumption based on the current Inland Revenue Department tax tables. Type values into any field and it will calculate the others.
