2025 Inst 990-PF (PDF) · 2026-10-03 edition · updated 2026-10-04 · United States
In Part XV-A, analyze revenue items that are also entered in Part I, lines 3–11, column (a), and on line 5b. Contributions reported on line 1 of Part I aren't entered in Part XV-A. For information on unrelated business income, see the Instructions for Form 990-T and Pub. 598.
Columns (a) and (c). In column (a), enter a six-digit business code, from the list in the Instructions for Form 990-T, to identify any income reported in column (b). In column (c), enter an exclusion code, from the list later, to identify any income reported in column (d). If more than one exclusion code is applicable to a particular revenue item, select the lowest numbered exclusion code that applies. Also, if nontaxable revenues from several sources are reportable on the same line in column (d), use the exclusion code that applies to the largest revenue source.
Columns (b), (d), and (e). For amounts reported in Part XV-A on lines 1–11, enter in column (b) any income earned that is unrelated business income (see section 512). In column (d), enter any income earned that is excluded from the computation of unrelated business taxable income by section 512, 513, or 514. In column (e), enter any related or exempt function income; that is, any income earned that is related to the organization's purpose or function that constitutes the basis for the organization's exemption.
Also enter in column (e) any income specifically excluded from gross income other than by section 512, 513, or 514, such as interest on state and local bonds that is excluded from tax by section 103. You must explain in Part XV-B any amount shown in column (e).
Comparing Part XV-A with Part I. The sum of the amounts entered on each line of lines 1–11 of columns (b), (d), and (e) of Part XV-A should equal corresponding amounts entered on Part I, lines 3–11, column (a), and on line 5b as shown below.

For each program service activity listed, enter the gross revenue earned for each activity, as well as identifying business and exclusion codes, in the appropriate columns. For line 1g, enter amounts that are payments for services rendered to governmental units. Don't include governmental grants that are reportable on Part I, line 1.
Report the total of lines 1a–g on line 11 of Part I, along with any other income reportable on line 11.
Program services are mainly those activities that the reporting organization was created to conduct and that, along with any activities begun later, form the basis of the organization's current exemption from tax.
Program services can also include the organization's unrelated trade or business activities. Program service revenue also includes income from program-related investments (such as interest earned on scholarship loans) as defined in the instructions for Part VIII-B.
Line 11. On lines 11a–e, list each “Other revenue” activity not reported on lines 1 through 10. Report the sum of the amounts entered for lines 11a–e, columns (b), (d), and (e), on Part I, line 11.
Line 13. On line 13, enter the total of columns (b), (d), and (e) of line 12.
