Form 990 Preparation for Nonprofits

The Form 990 is an annual IRS informational return for tax-exempt organizations. Unlike private income tax returns, your 990 is considered public information. This allows donors to freely evaluate your organization’s finances, mission, operations, and activities.


The cost of preparing a Form 990 can vary depending on your organization’s annual income, assets, and other details. To estimate your total costs, answer a few simple questions using our Form 990 Quote Calculator.


Like an audit or review, the Form 990 is an official financial representation of your organization, demonstrating transparency and accountability to donors. A well-prepared Form 990 can make all the difference in grant approvals, major donations, and nonprofit ratings from sites likes Charity Navigator and GuideStar.

There are several different types of Form 990 returns for nonprofit organizations.

Which Form 990 To File

To determine which 990 your nonprofit organization should file, you need to know two things:

  • Gross Receipts - The total amount your organization has received from all sources during your annual accounting period, without subtracting any costs or expenses.

  • Total Assets - The amount reported by your organization on your balance sheet (Statement of Financial Position) as of the end of the year, without any reduction for liabilities.

There are several different types of Form 990:
