What is PAYE?

A pay-as-you-earn tax (PAYE) is a withholding tax on income payments to employees. Amounts withheld are treated as advance payments of income tax due. They are refundable to the extent they exceed tax as determined on tax returns. PAYE may include withholding the employee portion of insurance contributions or similar social benefit taxes. In most countries, they are determined by employers but subject to government review. PAYE is deducted from each paycheck by the employer and must be remitted promptly to the government.

See Wikipedia for more on PAYE

By default, this calculator applies the Independent Earners Tax Credit (IETC) for values which would qualify.

How do I calculate secondary tax?

Secondary income is calculated at a fixed rate based off your total income from all sources. The secondary tax rates are aligned with the main tax bands.

For example, if you earn a total of $50k from all sources of income and you secondary job earns $14k of that total. The $14k will need to be taxed at a fixed rate of 30%.

Why build it?

I built my first take home pay calculator (using Flash) prior to my first full-time job. I wanted a simple way to calculate what my pay was going to be. When I was going to receive my first pay rise, I wanted to know the percentage increase it would be after tax. When a lot of Kiwis were flocking to Australia I wanted to see what I could be earning across the ditch. When two political parties were promising tax cuts leading into an election, I wanted to see what they were bribing me with.

So ultimately I built it for my own interests, but I'm happy to share it with the world.
