My partner and I were having a debate.
She says that if you work two jobs you are taxed more heavily than if you work a single job for the same amount.
E.g. someone working two jobs earning $25000 each will pay more tax than someone working a single job at $50000.
I say that while the flat tax rate on secondary income may result in you paying more tax throughout the year, that your tax obligation is based on total income (regardless of the number of jobs) so you be entitled to a tax refund of the difference.
The IRD website doesn't seem to be entirely clear on this (at least to me), so which one of us is correct?
