Every client's 1099-NEC in one sheet
If you freelance for several clients, tax season brings a stack of 1099-NECs, each a PDF with the same few numbers in slightly different places. StubCSV pulls box 1 and the withholding boxes from each form so you can line them up against your own invoice records and spot a missing or wrong form before you file.
Use the detailed CSV for one row per box, or the one-row summary to add each 1099 as a single line in a running spreadsheet.
How to check your 1099s against your invoices
Convert each client's 1099-NEC and download the one-row summary CSV. Paste the rows into one sheet so each client is a line with payer name and box 1 compensation. Next to it, add what you invoiced and were paid by that client during the year.
Any gap between the two columns is worth a second look: a payment made in a different tax year, a form issued under the wrong name, or a missing 1099 entirely. Following up with the client early is easier than after you file.
1099 to CSV: which forms are supported?
StubCSV reads Form 1099-NEC, the form most freelancers and independent contractors receive for client work. Other 1099 variants such as 1099-MISC, 1099-K, and 1099-INT aren't supported yet. If you upload one, you'll get a clear message instead of wrong numbers.
For bookkeepers and tax preparers
Moving 1099 data from client PDFs into a workpaper is repetitive work. StubCSV turns it into a drag-and-drop step while keeping sensitive data out of storage: recipient TINs come back masked to the last four digits, and nothing is kept on our servers.
