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.

Features

The numbers that actually matter

01

Real net profit, per item

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

02

Month to date, every month

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

03

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.

04

Parsed on your device

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

Reconciliation

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.

Ties out to the cent

Filing-ready Schedule C worksheet with line-by-line amounts to copy
Filing ready. Everything ties out, so you get the worksheet: line-by-line amounts you can copy straight onto a Schedule C.
Draft-only exception report shown when the gross does not tie out
Draft only. The gross is off by 30.00, so no filing-ready number. You get an exception report and help resolving the discrepancy.
