Poshmark Profit + Tax

Import your Poshmark Sales Report CSV to see real net profit per item and generate a 1099-K reconciliation worksheet. Local-first.

Know your real numbers as a Poshmark seller, and file with confidence. Poshmark Profit + Tax turns your own official Poshmark Sales Report into the numbers that actually matter: real net profit per item, month to date, and a year-end 1099-K reconciliation you can copy straight onto a Schedule C. How it works 1. Download your Sales Report from Poshmark (Account, My Seller Tools, My Sales Report) and email yourself the CSV. 2. Upload the CSV into the extension. It is parsed on your device. 3. Enter your cost of goods per item, one tap each. It is saved and reused. 4. See per-item net profit, month to date, and monthly totals. 5. At tax time, enter your 1099-K Box 1a gross and get a copy-paste-ready Schedule C worksheet. Built to be honest It refuses to hand you a filing-ready number it cannot reconcile. Every row must check out and your records must tie out to your 1099-K gross to the cent. If something is off, it shows a clear draft exception report and helps you resolve it, instead of quietly producing a wrong number. Private by design Your financial data stays on your device. There is zero automated collection from Poshmark: you upload a report you downloaded yourself. Minimum permissions, no host access, no tracking, nothing sold. Free and Pro The free tier shows your recent items and their profit. Pro unlocks your full history and the year-end 1099-K worksheet. No banners, no interruptions. This tool helps you organize your own records. It is not tax advice. Always verify against your official Poshmark documents before filing.
