Tax Time Document Cleanup: What to Keep, What to Shred

Post-Tax Season Document Management

After another tax season, many Perth businesses are left with mountains of financial documents. The question is: what can you safely shred, and what must you keep?

ATO Document Retention Requirements

The Australian Tax Office has clear guidelines on how long you must retain various documents:

5-Year Retention (Minimum)

  • Income tax records
  • BAS and GST records
  • Deduction receipts
  • Bank statements
  • Investment records

7-Year Retention

  • Fringe benefits tax records
  • Capital gains records (some cases)
  • Superannuation records
  • Employment records

Indefinite Retention

  • Records of asset purchases (until disposal)
  • Any records subject to audit or dispute

Safe Document Destruction Schedule

After the required retention period:

1. Immediate Destruction - Documents beyond retention period 2. Review First - Records that may support ongoing claims 3. Keep Forever - Property purchases, major investments

The Risks of Keeping Too Long

While retention is important, keeping documents indefinitely creates risks:

  • Increased storage costs
  • Higher breach exposure
  • Clutter reduces efficiency
  • Discovery obligations in litigation

Organising Your Annual Shredding

Best practice is an annual document review:

January-February

  • Review previous financial year documents
  • Identify documents past retention period
  • Schedule secure destruction

Post Tax Lodgement

  • File current year documents
  • Destroy superseded documents
  • Update retention schedules

Business vs Personal Documents

Requirements differ for business and personal records. Ensure you understand which retention rules apply to each document type.
