Building a Repeatable T4A Process for Your Practice: Templates, Checklists, and Tools

If your T4A season feels different every single year—different spreadsheets, different fire drills, different “we’ll remember next time” lessons—you don’t need more willpower. You need a repeatable process.

A repeatable T4A process turns chaotic, one‑off efforts into a set of templates, checklists, and tools your whole team can rely on.

Here’s how to build that for your practice.

Step 1: map your current reality

Before designing the ideal, document what actually happens now. Ask your team:

• How do we currently find out which clients need T4As? 
• How do clients send us contractor and payment data? 
• Who does what—intake, prep, review, filing? 
• Where do things usually go wrong or get delayed?

Capture this in a simple flowchart or bullet list. This “as‑is” map will show you where templates and tools can help most.

Step 2: create a client‑facing T4A information kit

Start by standardizing what you send to clients. Your kit might include:

• A one‑pager explaining what T4As are and why they matter 
• Clear deadlines and what happens if they’re missed 
• A standardized contractor data template (for example, Excel or a form) 
• Instructions for exporting payment data from common accounting systems 
• Contact details for questions

By sending the same kit to every T4A client, you reduce one‑off explanations and set expectations early.

Step 3: build internal checklists for each stage

Next, create simple checklists for your team. For example:

Intake checklist:

• [ ] Confirm client is in T4A scope this year 
• [ ] Send T4A information kit and templates 
• [ ] Receive and log contractor and payment data 
• [ ] Check for obvious gaps (missing names, zero totals, etc.) 
• [ ] Assign file to preparer

Preparation checklist:

• [ ] Import contractor and payment data into T4ASlip or internal tool 
• [ ] Match contractors to payments and review totals 
• [ ] Flag missing SINs, addresses, or unusual amounts 
• [ ] Prepare draft slips and summary

Review and filing checklist:

• [ ] Senior review of draft slips 
• [ ] Resolve any questions with client 
• [ ] File slips with CRA 
• [ ] Send copies to recipients 
• [ ] Archive records according to retention policy

These checklists don’t just reduce errors—they also make training new staff easier.

Step 4: standardize your templates

Templates reduce cognitive load. Consider creating:

• Email templates for initial outreach, reminders, and final confirmations 
• A standard spreadsheet layout for contractor data (if not using online forms) 
• A simple internal memo template for documenting tricky classification decisions 
• A post‑season debrief template (“what worked, what needs improvement”)

Store these in a shared location labeled clearly for “T4A Season” so staff can find them quickly.

Step 5: choose tools that support the process

Once you have checklists and templates, pick tools that make them easier to execute. T4ASlip can play a central role by:

• Serving as the hub for contractor and payment data 
• Automating imports and basic validations 
• Generating slips and summaries with minimal manual entry 
• Providing a clear view of file status across your client base

Pair T4ASlip with your practice management and document management systems, and you have a strong backbone for your T4A process.

Step 6: define roles and handoffs

Confusion about “who does what” creates delays and dropped balls. For each stage, define:

• Who owns the step (role, not just a person’s name) 
• What input they need to start 
• What output they must produce 
• Who they hand off to next

Example:

• Client manager owns initial outreach and expectations 
• Staff accountant owns data prep and T4ASlip setup 
• Senior or manager owns review and sign‑off 
• Admin or filing specialist handles CRA submission and record archiving

Put this into your internal playbook so everyone sees the full picture.

Step 7: schedule the process

A repeatable process also needs a repeatable calendar. Build a simple T4A timeline:

• Early fall – identify T4A clients; update contact details 
• Late fall – send information kits and templates 
• Early January – intake data and begin preparation 
• Mid‑January – internal preparation and review 
• Before CRA deadline – final filing and confirmations

Block time for these phases in your practice calendar just like you would for other recurring work.

Step 8: practice continuous improvement

After each T4A season, hold a short retrospective with the team:

• What steps worked well? 
• Where did we get bogged down? 
• Which checklist items were unclear or unnecessary? 
• What should we change in T4ASlip or other tools?

Update your templates and playbook while the experience is still fresh.

The payoff of a repeatable process

When your T4A process is documented and supported by tools like T4ASlip, you get:

• Fewer errors and last‑minute crises 
• Faster onboarding of new staff 
• Less frustration for both your team and your clients 
• A foundation you can refine year after year

Most importantly, T4A work stops feeling like a one‑off scramble and starts feeling like what it should be: a predictable, manageable part of running a modern practice.
