Nonprofit agencies are subject to various tax breaks due to their charitable nature, and as such their financial information, including employee salaries is available for the public to view. The Internal Revenue Service (IRS) allows for transparency of financial information due to the fact that these companies are receiving public benefits.

Visit the non-profit agency during business hours. According to FindLaw.com, non-profit agencies are required to disclose financial information to the public. This financial information includes employee salaries. If you are a job hunter you may not want to show up at a new potential place of employment and ask for salary information without first getting an interview. It's possible, however, to visit a similar agency in the area to compare salary information to the company for which you wish to work.

Write a letter of your request for salary information to the Internal Revenue Service and send it to:

Non-profit agencies are subject to special tax relief programs and must report their financials using a Form 990. The information on the Form 990 is available as public information. Be sure to clarify the specific organization and tax year you wish to view in your written request.
