For GST/ HST filling for Uber, is line 101 same as line 150 in income tax. I mean which amount to put in line 101.

On the T1 income tax return, Line 150 is your total income from all sources, so it may include income from sources other than Uber. On your GST/HST return, you should only include income from Uber.

Please contact the CRA if you need help with your GST/HST filing. You can all them at 1-800-959-5525 for business inquiries.
