What IRS Form 990-PF (2024) Is For

Form 990-PF is the annual tax return that all private foundations—including tax-exempt and taxable private foundations, and Section 4947(a)(1) trusts treated as private foundations—must file with the IRS (IRS Instructions for Form 990-PF (2024)). The form serves dual purposes: calculating and reporting the excise tax on net investment income, and reporting charitable distributions, activities, and compliance with minimum distribution requirements.

When You’d Use Form 990-PF for 2024 (Late or Amended Filing)

You would file Form 990-PF for 2024 in late or amended situations when: you missed the original May 15, 2025 deadline (or November 15, 2024 for foundations with June 30, 2024 fiscal year-end) and received IRS penalty notices; you need to correct errors or omissions from your original filing; or you're filing to avoid automatic revocation of tax-exempt status after missing previous years. Private foundations that fail to file for three consecutive years automatically lose their tax-exempt status and must file as taxable private foundations (IRS Instructions for Form 990-PF (2024)). Late filers may also need to address accumulated penalties and potentially establish payment plans for unpaid excise taxes from prior years.

Key Rules Specific to 2024

• Excise tax rate: Private foundations pay a flat 1.39% excise tax on net investment income.
  
  
• Minimum distribution requirement: The 5% payout rule applies based on prior year non-charitable assets.

What Happens After You File

The IRS usually processes Form 990-PF within 6–8 weeks for electronic filings and 8–12 weeks for paper filings. Delays can occur during peak seasons or if amendments are required. If taxes are owed, the IRS sends assessment notices, and payment plans may be arranged using Form 9465. Late filings accrue penalties until the complete return is received. You retain appeal rights for penalties and can request abatement for reasonable cause.

FAQs

What penalties apply for filing my 2024 Form 990-PF late?

The penalty is $25 per day for smaller foundations and $125 per day for larger ones with gross receipts over $1,274,000. Maximum penalties are $12,500 and $63,500, or 5% of gross receipts, whichever is less. Penalties accrue until the IRS receives a complete filing, making prompt submission critical to minimizing financial exposure.

Can I still get an extension if I missed the May 15, 2025 deadline?

No, extensions using Form 8868 must be filed by the original due date. However, filing as soon as possible limits penalties and helps protect tax-exempt status. The IRS may consider reasonable cause for penalty relief if the delay was due to circumstances beyond your control, such as illness or natural disasters.

How do I get copies of prior year returns to file amended returns?

You can request prior year return information by filing Form 4506-T for free account transcripts or Form 4506 for complete return copies, which require a fee. Alternatively, IRS business accounts may allow online access. Having accurate prior year data ensures amended returns are properly prepared and avoids compounding reporting errors.

What if my foundation owes excise taxes from multiple years?

If your foundation owes excise taxes across several years, you can request an installment agreement using Form 9465 or apply online through IRS.gov. Streamlined agreements are available for smaller balances, while larger amounts may require negotiation. Filing all overdue returns and arranging payments promptly reduces penalties, interest, and compliance risks with the IRS.

Should I amend state returns when filing federal amendments?

Yes, in most cases. Many states accept the federal Form 990-PF for nonprofit reporting, but they may require amended filings when a federal return is corrected. State attorney general or charity registration offices often mandate copies of amended federal filings to maintain compliance with fundraising and state-level registration obligations.

What’s the statute of limitations for claiming refunds on overpaid excise taxes?

Refund claims for overpaid excise taxes generally must be filed within three years of the original return’s due date or two years from the date the tax was paid, whichever is later. Filing promptly ensures eligibility, and amended returns must be accurate and include supporting documentation for the IRS to process refund requests.

How long must I keep records after filing Form 990-PF?

Foundations must keep all records supporting Form 990-PF for at least three years after filing. This includes financial statements, grant documentation, investment records, and correspondence with the IRS. However, best practice is to keep records longer, as state regulators and public inspection requirements may extend beyond federal minimums for nonprofit organizations.
