Preparation resource. Editorial review: November 3, 2026. This guide helps organize records and questions; it does not determine your tax position. Use the agency instructions for the relevant year and obtain advice for your circumstances.
Records to organize
Prepare the records that relate to your situation and keep the original supporting statements. Use the same filing year or clearly labelled periods so the reviewer can follow the history.
- T2200 where applicable
- Employment duties and reimbursement policy
- Expense receipts, workspace records and payment evidence
How to use these records
Keep the employer's completed certification with duties, expense and reimbursement records. The certification supports review but does not by itself make every cost deductible. Confirm the applicable year and method, especially where remote-work arrangements changed.
The question to resolve before filing
Which employment conditions and expenses are supported by the employer and the records?
Start with the facts you can support. Identify missing statements, corrections and earlier filings instead of filling a gap with an estimate that has not been discussed. Tell the team which countries, tax years and agencies are involved so the engagement can cover the right work.
A mistake to avoid
Do not assume working remotely by itself makes every home or technology cost claimable.
A clear handoff to your preparer
- Label the evidence. Keep each record with its relevant year, account or activity.
- List open questions. Share missing information and anything that differs from the prior return.
- Confirm the scope. Ask which returns, disclosures and follow-up work are included before preparation begins.
Do not enter identity numbers, account numbers, verification codes or tax-document copies in a public enquiry. Use your private client portal for requested records after onboarding.
Official starting points
Use the current agency guidance and the instructions for the applicable filing year. A source link is not confirmation that a particular rule, election or claim applies to your circumstances.
