Tax Guide for Penny Resellers: Income Reporting and Deductions

Understanding 1099-K Reporting Threshold

The IRS lowered the 1099-K threshold to $600 in 2024, down from previous $20,000 threshold. If you sell through eBay, Mercari, Amazon, or Poshmark, payment processors like Stripe, PayPal, or Square track your gross sales. At $600+, the platform issues Form 1099-K to you and the IRS. This doesn't mean you owe taxes on $600—your tax obligation is gross sales minus expenses and cost of goods sold. Example: $2,000 gross sales, minus $1,200 cost of penny items, minus $300 shipping and fees, leaves $500 taxable income. The 1099-K reports the $2,000 gross figure, which is why bookkeeping is critical to prove deductions. File Schedule C to reconcile the difference.

Schedule C Filing for Self-Employment Income

Schedule C (Form 1040, Part II) is where you report self-employment income and business deductions. File on your annual tax return (Form 1040-1040SR). Part I requires Gross income from sales minus returns/allowances. Part II itemizes Cost of Goods Sold (COGS): penny items purchased. Part III lists deductible expenses: supplies, shipping, platform fees, mileage, home office, phone, professional services. IRS expects detailed records. Filing Schedule C requires keeping receipts, invoices, sales records, and expense tracking for at least 3 years. Failure to file Schedule C when you have a 1099-K increases audit risk. Consult a CPA before filing for the first time—they verify calculations and identify additional deductions.

Tracking Income and Expenses

Start a simple spreadsheet or use bookkeeping software. Columns needed: Date, Description, Category (COGS, Shipping, Platform Fees, Supplies), Amount. Track daily. Penny item costs go in COGS line (not deductible separately). Shipping supplies, poly mailers, bubble wrap, labels, tape go in Office Supplies. eBay, Mercari, Amazon fees go in Platform Fees (these are business expenses, deductible). Gas to Dollar General and post office goes in Mileage/Vehicle. Record: receipt date, amount, purpose. Keep digital copies (photo or scan). At year-end, sum each category. Example annual breakdown: COGS $8,000, Shipping Supplies $400, Platform Fees $1,200, Mileage $600, Total Expenses $10,200 against $12,000 gross sales.

Deductible Expenses for Resellers

Cost of Goods Sold (COGS): Each penny item you buy is 100% deductible, subtracted from gross sales before calculating profit. Shipping supplies: Poly mailers, boxes, tape, bubble wrap, labels, printing paper—all deductible. Packaging from USPS, UPS, FedEx—free, no deduction needed. Platform fees: eBay's final value fee (13.25% on most items), payment processing fees (2.2% average), Mercari commission (10%)—all deductible. Vehicle mileage: If you drive to Dollar General, post office, shipping locations, deduct miles at $0.67 per mile (2024 rate). Track miles daily using a logbook or app like MileIQ ($5.99/month). Home office: If you use a dedicated room/area for packing and photos, deduct a percentage ($0.05 per square foot simplified method or actual costs). Phone and internet: Portion used for business. Professional services: CPA tax prep fees, bookkeeping software ($10-$50/month).

Quarterly Estimated Taxes

If you expect to owe $1,000+ in taxes for the year, make quarterly estimated tax payments (Form 1040-ES). Payments due: April 15, June 15, September 15, January 15. Example: Projected $12,000 gross sales, $10,000 expenses, leaves $2,000 profit. At 25% combined federal + self-employment + state (varies by location), you owe $500 quarterly or $2,000 annually. Underpaying estimated taxes triggers penalties and interest. Many resellers skip this and owe a large bill in April. Pro tip: Set aside 25-30% of profits monthly in a savings account, pay quarterly in lump sums, or use IRS Direct Pay (free online payment). Spreadsheet reminder: Track profit monthly and divide by quarter to know what you owe.

Bookkeeping Tools: Spreadsheet vs Software

Simple spreadsheet (Excel, Google Sheets): Free, requires discipline, works for under $50,000 annual sales. Columns: Date, Description, Category, Amount In/Out. Review monthly, reconcile with bank. Upside: low cost, flexible. Downside: easy to fall behind, manually calculate taxes. QuickBooks Self-Employed ($6-$15/month): Tracks income, expenses, estimates taxes quarterly, generates Schedule C report, stores receipts. Syncs with your bank automatically. Wave (free with ad): Cloud-based, tracks income/expenses, invoicing, basic reporting. FreshBooks ($5-$50/month): More features, integrates with eBay, Mercari, Square, calculates mileage automatically. At $12,000 annual sales, spreadsheet is fine. At $50,000+, software saves time and audit risk. Many resellers start with spreadsheet, upgrade to software at $30,000+ revenue.
