Much like the other Form 990s, the 900 PF form is due on the 15th day of the 5th month following the end of your foundation’s tax year. If that’s on a weekend or holiday, you can file by the next business day. For those who use the calendar year as their tax year, they will need to file by May 15.
If you are unable to meet the deadline, you can file an extension. As long as it’s properly filled out, it will be automatically granted.
Detailed Examination of 990-PF Form
The 990 Form PF has 13 pages that foundations will need to fill out. In this section, we’ll cover what each section is and what you need to fill in. Because it is complex, it may be best to partner with a tax professional to ensure it is filled out correctly.

Before you dig in, you need to fill out basic information about your private foundation, including name, EIN, address, and the type of organization you are. You also need to summarize the fair market value of your assets and your accounting method.

If any of these are negative, you should enter 0.

This section asks that you add your net assets or fund balances from the beginning and end of the year and total them all up.

If you have any investment income, you’ll want to share all the information here, including any capital gains or losses that you have accrued in a year.

This section continues tracking information on your investment income, this time asking you to enter in any excise tax. At the end, you’ll total if you have overpaid or if you have any tax you need to be refunded.

There are two parts to this section:

You are required to disclose salary information for employees who are paid over $50,000 in a year, so make sure to include all whose compensation meets the criteria.

This section provides an additional opportunity to disclose how you’re spending money, both as charitable efforts and program-related investments. Total the expenditures at the bottom.

Enter any information about your investment returns. Keep in mind that foreign foundations may not need to fill out this section, so be sure to review the instructions.

In this section, you’ll build on the information you entered in part IX, sharing the distributable amount of your minimum investment return. This is another part that may be optional for select foundations, including {Section 4942(j)(3) and (j)(5)] private operating foundations and select foreign organizations.

This section asks that you enter how much you paid to accomplish your charitable purposes, including administrative expenses, assets, and more.

There are 10 questions with multiple subparts that you need to fill out about any undistributed income that you may have accrued in the past, including current and former tax years.

If you are a private operating foundation, you need to fill out this section, including information from the current and previous three taxable years.

This supporting information is only required if you had more than $5,000 in assets throughout the year. It asks for information about foundation managers, any contributions you’ve made, grants you’ve paid or plan to pay, and more.

Here you’ll summarize any additional activities that you did that produced additional income for your foundation. In the first section (A), you will list everything. In the second section (B), you will provide explanations of how they helped you accomplish your foundation’s purpose.

In the final section, you are asked to account for any business dealings that you engaged in with nonexempt organizations. You need to provide explanations and descriptions following the questionnaire.
