That sucks, but to be fair that's not really the situation. The basic personal amount is deducted from your income, so you pay near-zero tax.

You should be paying negative tax (i.e. getting a universal basic income), but you're not really paying any tax now.

Edit: the basic personal amount is increasing to 15.7K, so you'll be taxed at 10% of $300 if you don't have any other deductions at all, to the total tune of $30-ish.

Just because you're in the same bracket it doesn't mean you end up paying the same overall percentage at the end of the day.

Like the other comments mentioned, there's a basic personal amount to be deducted from so they don't start taxing you the first dollar you make.

Also in those income levels you get more back in the form of Canada Workers Benefit, a refundable tax credit which alone is probably enough to put your tax balance in the negative. On top of that you get more GST/HST credit, and if you're in BC a $0 deductible with pharmacare.

Have you ever done your taxes before?
