The Internal Revenue Service has issued a notice explaining how the public can request copies of a nonprofit organization’s Form 990-T, which lists unrelated business income.

All 990-Ts filed after August 17, 2006, are available from the IRS, but the agency does not currently have a way for people to request them. To make sure they are available, the agency is allowing people to adapt a form used to make requests for other documents (called the 4506-A) by writing a request for a 990-T on line 7 of the 4506-A.

(The 990-T can also be obtained by writing an individual charity directly to request a copy.)

The tax agency says it will change its request form in the near future to make it easier to secure a 990-T.
