Should I track every flip in a spreadsheet for taxes?
What a flip log should track
A useful log records the date you bought an item, where it came from and what you paid, including any sales tax you paid. It should also note the sale date, sale price, platform fees and shipping costs. These columns let you calculate profit per item and per sourcing trip.
Use the same naming pattern for every file and photo tied to a purchase. That way you can match a receipt to a sale in seconds.
Simple record format
One row per item works well for most people, and a notes column can capture condition or lot details. Save receipts and screenshots of sold listings in one folder so they are easy to find later. Keep the format the same month to month so comparisons stay useful.
Back up the spreadsheet on a second device or cloud folder so a lost laptop does not erase your history.
Where the records help at filing time
How resale income is reported depends on your location, your sales volume and whether you run the activity as a business. Good records make that conversation with a tax preparer faster and less stressful. Ask a qualified professional about your situation, because general rules vary and this is not personal tax advice.
Common mistakes
- Waiting until tax season to rebuild months of purchases from memory.
- Logging sales but forgetting the cost of cleaning supplies and postage.
