Save the paystub from Gusto, not a screenshot
Employees usually sign in at app.gusto.com. The Gusto mobile app opens the same documents. Look under Pay or Paystubs. Some companies also file them under Documents. Open the pay period you need and download the PDF.
If your employer emails paystubs, the PDF attachment is the right file, as long as it is a real PDF and not a screenshot pasted into a message. The on-screen view in Gusto is not itself a file you can upload. Download it, or use Print and Save as PDF if that is the option the page gives you.
What a Gusto paystub turns into
Gusto paystubs are often a single page: earnings, employee taxes, and benefit deductions, sometimes with a reimbursement or a company contribution. StubCSV sorts those lines into earnings, taxes, deductions, or employer contributions. A company match or other employer-paid line stays in the employer contributions category, so it is not treated as money withheld from your net pay.
Gross pay, total taxes, total deductions, and net pay are summary rows. Year-to-date figures are included when Gusto printed a YTD column. Rate and hours show up on earnings lines when those figures are on the row. Your company's earning names stay as printed. We don't rename them to a generic list.
See where a small-company paycheck went
The useful question on a Gusto stub is usually where the gross went: tax withholding, medical, retirement. Convert a few months, paste the CSVs under each other, and total a category without retyping. For a simple income log, the one-row summary CSV puts one paycheck on one row so you can append it to a running sheet.
Check the reconciliation line before you treat the sheet as your budget. It compares gross minus taxes minus deductions with net pay. If a reimbursement or a one-off line means those don't agree, you'll see the difference and can match it against the PDF. Gusto still lets each company pick earning codes, so this is not a fixed template we special-case.
