How to Get Tax Transcripts and Copies of Tax Returns from the IRS

Hi.  I need this information too.  When I go to the page you show via link I see:

 

Caution: The Get Transcript Service is for individual taxpayers to retrieve their own transcripts for their own purposes. Use by any other entities is prohibited.

 

I see no place to order a business tax return transcript, form 1120, online.  Can I make an appointment at a local IRS center to pick it up in person?

 

You may be able to pick one up in person or mail the 4506-T

Other options for obtaining a 1120 transcript are listed below. 

 

To get a transcript, people can:

• Order online. Use the ‘Get Transcript ’ tool available on IRS.gov. There is a link to it under the red TOOLS bar on the front page. Those who use it must authenticate their identity using the Secure Access process.
• Order by phone. The number to call is 800-908-9946.
• Order by mail.  Complete and send either Form 4506-T or Form 4506T-EZ to the IRS to get one by mail. Use Form 4506-T to request other tax records: tax account transcript, record of account, wage and income and verification of non-filing. These forms are available on the Forms & Pubs page on IRS.gov

Transcripts available through submission of IRS Form 4506-T include the following series:

▪ 1040: U.S. Individual Income Tax Return

▪ 1065: U.S. Return of Partnership Income

▪ W-2: Wage & Tax Statement

▪ 1098: Mortgage Interest/Student Loan Interest/Tuition Statements

▪ 1099: Dividends/Interest, Miscellaneous Income, Government Payments, Cancellation of Debt, etc.

▪ 1120: U.S. Corporation Income Tax Return (also 1120-L and 1120-S)

▪ 5498: IRA, HSA, Archer MSA, Medicare Advantage MSA, Coverdell ESA Contributions The table below shows the documentation that should be requested from the IRS. The requested documentation must follow Fannie Mae’s income documentation requirements, which depend on the type of borrower income (self-employed, salaried, commissioned, etc.) and the underwriting method (DU or manual).
