If you have more than one source of income, and tax is deducted from that income, then you will need a secondary tax code. Your primary tax code only covers your main source of income.
Some may feel that it is unfair they may be taxed at a higher rate on a second income, however those living in New Zealand are taxed on a progressive scale. This means that if it weren’t for secondary tax codes, you may receive an unexpected tax bill at the end of the year.
For example, if your income from each employer was around $30,000, each employer would deduct the correct tax amount namely 17.5%. However, the sum total of income is $60,000, which places you in a different tax bracket as your total earnings exceed 48K. The Inland Revenue would then seek the shortfall.
The current tax thresholds are:
|$0 – $14,000||10.5%|
|$14,001 – $48,000||17.5%|

Problems you may encounter with Secondary Tax
Most of the time, you will pay the right tax if you’re using the correct secondary code. Problems with over and underestimation can occur when someone crosses one of the tax thresholds.
