IRS Form 8453 is a U.S. tax form specifically designed for taxpayers who file their tax returns electronically but must submit certain paper documents that cannot be electronically filed. This form is a transmittal document for these paper records, ensuring they are properly linked to the electronic submission.
Common attachments that require this form include forms related to elections made by the taxpayer, supporting documentation for a tax credit, or schedules for certain types of income. By using Form 8453, taxpayers can maintain the advantages of electronic filing, such as faster processing and receipt confirmation, while complying with the requirement to provide documentation in paper form.
