For those of you who think Secondary tax penalises you, go to the ird website, signup and file a tax return. If you have been paying secondary tax, it is highly likely the IRD
will give you some money back, this could be quite a lot. They have to charge a secondary tax as your second employer won’t know what you earn with your other job, it is a lot better to get money back at the end of the year, than be lumped with a massive tax bill instead.

PS, don’t sign up to the likes of woohoo tax returns, they are a con, you can do it all online with IRD
for the same amount of effort!
