"Nobody told us we had to file a T5018 for our subcontractors. ATA caught it before the deadline and filed it for us."

Challenges
What Goes Wrong Without the Right Tax Service?
- The six-month T2 deadline slips past while year-end work is still open
- GST/HST returns are filed without claiming every input tax credit
- SR&ED claims never get made because the documentation feels too complex
- Annual returns go unfiled, putting the corporation at risk of dissolution
- Contractor payments go unreported when a T5018 is required
- A CRA review letter arrives with no one ready to respond
