“I work 3 part time jobs, from none of which I earn enough to have taxes taken off? Why do I owe?”
This is a common question. The answer to this, is that when payroll is calculated for each part time job, the payroll software believes that this is the only job that you have, therefore only taking the minimal of income tax off of your pay cheque. When the income from all 3 jobs are totaled it puts you into a higher tax bracket, therefore income tax will possibly be owing.
SUGGESTION: Request one of your employers to take income tax off of each pay, therefore reducing the amount owing when your taxes are completed.
