Preparing a T1 personal tax return looks simple on paper: collect the slips, key them into your software, review, file. In practice a single return touches dozens of documents from multiple sources, and the season that produces them is compressed into a few intense weeks. T-slips arrive at different times, clients forget receipts, and CRA Auto-fill rarely captures everything. When a firm runs each return ad hoc, small gaps compound: a missing T5008 surfaces after the draft is built, a T183 sits unsigned while the deadline approaches, and the preparer ends up chasing the same things on every file.
A repeatable process is what keeps a high-volume T1 season from turning into firefighting. When every return follows the same sequence of steps, the same client requests, and the same review gate, anyone on the team can pick up a file and know exactly where it stands. That consistency is the difference between a predictable April and a scramble. It also protects tax compliance: nothing gets filed before the authorization is in hand, and nothing gets missed because the checklist forgot it.
When to run it
Run this during T1 season, in the run-up to the late-April filing deadline for individual returns. Start the file as soon as the client’s first slips begin to arrive so collection and preparation can overlap rather than stack up at the end. The firm owner or tax lead typically owns the workflow, assigning preparation and review while keeping an eye on which returns are still waiting on documents or signatures.
How to run it in Tidyflow
Set this up once as a reusable job template, then apply it to every T1 client. Each step becomes a subtask your team checks off, so preparation, review, and filing always happen in the same order. Make the job recurring on an annual cadence so next year’s returns generate automatically without rebuilding anything.
The document side runs through the client portal: send requests for income slips, deduction receipts, and confirmation of personal details, and clients upload directly against each item. When the draft is ready, route the T1 summary back for approval and collect the signed T183 authorization. Pair this with document management so every slip, working paper, and piece of CRA correspondence is archived against the client, and lean on workflow management to see which returns are stuck and where.
Common pitfalls
- Filing before the signed T183 is received. The authorization must be in hand before you e-file, so treat it as a hard gate, not a formality.
- Trusting CRA Auto-fill as complete. It misses slips that arrive late or are not yet reported, so reconcile against what the client actually received.
- Overlooking prior-year carryforwards such as unused RRSP room, capital losses, or tuition credits.
- Missing provincial-specific credits and benefits that vary by the client’s province of residence.
- Starting collection too late, so slips, receipts, and self-employment summaries all land at once against a tight deadline.
