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.
- Purchase and sale closing statements
- Improvement records and relevant prior depreciation
- Ownership, occupancy and rental-use timeline
How to use these records
Prepare a purchase-to-sale timeline with periods of personal, rental and business use. Ask the preparer to review gain, possible exclusion and depreciation-related questions separately. A property being your home at the time of sale does not establish every condition for relief.
The question to resolve before filing
What evidence supports the property's cost and use history, and which exclusions or reporting rules need review?
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 a gain is excluded solely because the property was called your home.
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.
