While reporting regular employment income, it&#8217;s easy to overlook additional revenue earned from side jobs. This can include income from part-time or freelance work, investment income, or even money received from a rental property or other sources while reporting regular job earnings.<\/p>\n\n\n\n<p>All income must be accurately reported to avoid problems during an audit.

The Canada Revenue Agency permits tax deduction G1 general tax claims for medical costs, childcare expenses, and selected employment costs. The Canada Child Benefit and the GST\/HST credit substantially diminish your total tax amount. For tax savings optimisation purposes, you must research eligible deductions and credits. Deductions reduce taxable income, but improper claims may lead to an audit. The most common mistakes are:<\/p>\n\n\n\n<p>Work-from-home expenses overstated<\/p>\n\n\n\n<p>Medical expenses claimed that are not eligible<\/p>\n\n\n\n<p>RRSP contributions not deducted correctly<\/p>\n\n\n\n<p>Student loan interest deductions missed<\/p>\n\n\n\n<p>If you are self-employed, use the T1 General Tax Form for Self-Employed Canadians correctly to ensure proper business expense deductions.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">* Missed or Misreported Income<\/h3>\n\n\n\n<p>If you fail to report all income sources, it may result in penalties if you miss the CRA tax deadline.
