Chrome extension for Poshmark sellers

Know your real numbers.
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.

Local-first. Your financial data stays on your device.

The profit dashboard: per-item net profit from your own sales report.

The numbers that actually matter

Real net profit, per item

Your actual Poshmark earnings for each item minus your cost of goods. Cancelled and refunded orders net to zero.

Month to date, every month

See per-item net profit, month to date, and monthly totals the moment your report is imported.

A Schedule C you can copy

At tax time, enter your 1099-K Box 1a gross and get a copy-paste-ready Schedule C worksheet.

Parsed on your device

You upload a report you downloaded yourself. Zero automated collection, no tracking, nothing sold.

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.

Your records gross 345.49
1099-K Box 1a gross 345.49
Difference 0.00
Year-end 1099-K reconciliation marked filing ready: all six rows classified, records gross ties out to the 1099-K gross, and a Schedule C worksheet is generated with line-by-line amounts.

Filing ready. Everything ties out, so you get the worksheet: line-by-line amounts 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. Email yourself the CSV.

  2. Upload the CSV into the extension

    It is parsed on your device. Nothing is sent anywhere.

  3. Enter your cost of goods per item

    One tap each. It is saved and reused on the next import.

  4. See your real profit

    Per-item net profit, month to date, and monthly totals.

  5. Reconcile at tax time

    Enter your 1099-K Box 1a gross and get a copy-paste-ready Schedule C worksheet.

Your financial data stays on your device. There is zero automated collection from Poshmark: you upload a report you downloaded yourself.
