Special situations requiring longer retention
Property records: Keep indefinitely if you own real estate. You'll need purchase price, improvement costs, and depreciation records when you sell.

Business assets: Keep records for 3 years after you dispose of the asset.
What you should do
1. Set up a filing system - physical or digital - organized by tax year
2. Scan important documents if storing digitally
3. Set calendar reminders to review and purge old records after 3 years
4. Keep a separate file for documents you'll need longer (property, retirement)
5. Store copies in multiple locations (home safe + cloud backup)
