Good to know

  • Use the PDF from the tax software or a clear scan, not a photo. Pages should be upright and readable.
  • Put one return in each file. A file that holds two returns, such as two years in one PDF, can't be used.
  • Upload the whole return, including the first page: the form number and tax year are printed there.
  • Each file can be up to 10 MB and 300 pages.
  • A project holds up to 10 returns, all for one company.
  • Password-protected PDFs can't be read, even ones that open without a password. Print the return to a new PDF (or save a copy without the password) and upload that.

If something goes wrong

  • "We couldn't find a federal 1120, 1120-S or 1065 in this file." A state return or any other document shows this. Check the file and upload the federal return.
  • "We support tax years 2015 and later." The year we read is before 2015 or later than this year. Check the year printed on the first page.
  • Not supported. The file is a Form 1040. Sidesheet reads business returns only, so remove the file.
  • "This file isn't a PDF." Save or print the return as a PDF and upload that.
