Annual revenue, all sources

Calculating Total Annual Revenue

It’s simple: This is the number you report on IRS Form 990, Part VIII Statement of Revenue, Column A Total Revenue. Or, if you are fiscally sponsored, your sponsor can give you your total program income from all sources.

INN’s membership year is July 1 – June 30 each year.
