Tip: Always insure that you report all forms of income, indeed those you might not admit a formal slip for( like tone- employment income, tips, or gig work). Double- check your T4s, T5s, and other duty slips before form.

4. Misreporting particular and Business Charges
For small business possessors, another frequent error is mixing particular and business charges. While numerous charges related to running a business are deductible, particular charges are not. However, the CRA will flag your return, If you claim particular charges as business- related.
Example If you claim a portion of your groceries as a business expenditure because you work from home, that could be a red flag for the CRA, especially if you don’t have proper records to back up the claim.
Tip Keep detailed records of your business charges. Use separate bank accounts and credit cards for business deals to make it easier to track and justify your charges.
5. Filing Late or Missing Deadlines
