While nowhere near as significant as the 2008 revisions to the Form 990, the changes that the Internal Revenue Service has made to the 2010 version of the Form 990 are still noteworthy. Below is a selection of some of the more significant revisions to the 2010 Form 990:

• Parts of the Form 990 core form now include a box to check if an explanation relating to them is included on Schedule O.
• Narrative sections have been added to Schedules E, G, K, L, and R. The Internal Revenue Service has stated that it wants Schedule O to be used to provide more information regarding Form 990 core form items.
• For public charities that have made the section 501(h) lobbying election, those groups must now complete Part II-A of Schedule C even if no lobbying expenditures were made in the tax year being reported on.
• If members of the governing board receive a Form 990 with redacted information, Part VI, Line 11 of the Form 990 must be responded to negatively.
• In Part IX, the Statement of Functional Expenses, you will now be required to list five specific categories of expenses rather than just reporting expenses in a miscellaneous expense account. Amounts that are listed as miscellaneous will need to be reported on Line 24f of Part IX.
