## Common compliance pitfalls & tips
- Track deadlines carefully: provincial/territorial returns may differ. Missing deadlines can delay benefit payments.
- Keep records for expanded deductions: e.g., critical mineral exploration, disability supports. Ensure expenses are documented with receipts, CRA eligible definitions.
- Review your residency status carefully: new service improvements mean information flows and enforcement may be tighter.
- If you previously used non-resident, nomadic or business classification, ensure you’re updated with changing rules and withholding requirements.
## Example scenarios
**Scenario 1:** John lives in Haida Gwaii and qualifies for reclassified northern zone status. He incurred travel and food costs because of geographic remoteness—those can now get deductible or credit treatments he didn’t have before.
**Scenario 2:** Priya has medical expenses more broadly under the expanded disability supports list (e.g. certain specialized treatments). She needs to review receipts carefully to ensure they are eligible and keep notes.
## Action checklist
- Use CRA’s online tools to check eligibility for pre-filled returns or SimpleFile Digital.
- Update your My Account / My Business Account communication preferences (email, notification settings).
- Gather documentation early—donations, disability expenses, mineral share agreements.
- Consult with a tax professional if you’re involved in flow-through shares, exploration, variable income.
