We recommend filing online with approved software or through a tax preparer. Filing by paper increases your chances of errors and paper returns take longer for us to process, which delays any refund you may receive.

You can also manually fill out and mail in your completed Individual Income Tax return (SC1040) and any supplemental forms.
Important: Please use the form listed under the current tax year if it is not listed under the year you are searching for.
