It's about both. You can be paid up to $65 per week without having any tax deducted from that payment. So if you are only paid $65 a week at your job, then you will keep the whole $65 each week. If you earn $75 a week, the first $65 will come to you complete but the remaining $10 will have tax deducted at whatever the current rate is. If tax is 25%, then you will only receive $7.50 of that $10, plus the original $65, leaving your weekly net income as $72.50.
