Seven years of delivery proof, with zero manual filing
CRA and Revenu Quebec require tax document retention for at least six years. The SESAR vault automatically retains proof of every document sent or received, including returns, financial statements and engagement letters, with the exact date the client accessed it. This evidence feeds directly into your accounting software, without anyone having to file a thing.
Fortin CPA sends 1,200 T1 returns in March. Two years later, the CRA launches a review of one of their clients and requests proof that the return was delivered to the taxpayer. Within seconds, the accountant retrieves from the SESAR vault confirmation that Mr. Pelletier opened his return on March 29 at 10:14 AM, with a complete audit trail.
