How long should tax returns be kept, and from which month does the retention period start?

• A. 3 years from January
• B. 5 years from January
• C. 7 years from January
• D. Indefinitely

Answer: (B)

The main idea is how long to keep tax records to be prepared for any audits, amendments, or inquiries. In this context, the retention period is five full calendar years, and the clock starts in January. So you keep all relevant documents for five years beginning each January and ending in December of the fifth year. This five-year window provides a practical balance between having enough documentation and not storing files indefinitely. Shorter (three years) might not cover all potential inquiries, longer (seven years) or indefinite storage is more than what this policy requires, so five years from January is the best-fit guideline here.
