Private foundations play a crucial role in supporting charitable activities, but they also have specific tax obligations that must be met to remain in good standing with the IRS. One such obligation is the excise tax on net investment income. This article explains what this tax entails, how it’s calculated, reporting requirements, payment options, and the consequences of late payment, complete with practical examples.
What Is the Excise Tax on Net Investment Income?
The IRS imposes an excise tax on the net investment income of most domestic private foundations. Net investment income includes interest, dividends, rents, royalties, and capital gains minus allowable deductions connected to producing that income.
Current Tax Rate
- After December 20, 2019: The excise tax rate is 1.39% of the foundation’s net investment income.
- Prior to December 20, 2019: The rate was 2%.

Reporting and Paying the Excise Tax
Form 990-PF
- Purpose: All private foundations must report their financial activities annually using IRS Form 990-PF.
- Excise Tax Reporting: The excise tax on net investment income is calculated and reported within this form.
Payment Options
- Annual Payment:
- Pay the total excise tax when filing Form 990-PF.
- Suitable if the total tax for the year is less than $500.
- Quarterly Estimated Payments:
- Required if the total excise tax for the year is $500 or more.
- Payments are made in four installments throughout the year.
Penalties for Late Payment
Failing to pay the excise tax on time can result in penalties and interest charges.
Late Payment Penalty
- Rate: 0.5% (one-half of 1%) of the unpaid tax for each month or part of a month it’s unpaid.
- Maximum Penalty: Up to 25% of the unpaid tax.
- Penalty Waiver: If there’s a reasonable cause for the delay, the IRS may waive the penalty.
Interest on Unpaid Tax
- Rate: Determined by I.R.C. Section 6621 and can vary over time.
- Accrual: Interest accumulates from the original due date until the tax is paid.
Practical Examples
Example 1: Annual Payment Under $500
- Foundation Alpha has a net investment income of $20,000.
- Excise Tax Calculation:
- 1.39% of $20,000 = $278.
- Action:
- Since the tax is less than $500, Foundation Alpha can pay the full amount when filing Form 990-PF.
Example 2: Quarterly Estimated Payments Required
- Foundation Beta has a net investment income of $200,000.
- Excise Tax Calculation:
- 1.39% of $200,000 = $2,780.
- Action:
- Required to make quarterly estimated payments because the tax exceeds $500.
- Quarterly Payment Amount:
- $2,780 ÷ 4 = $695 per quarter.
Example 3: Calculating Late Payment Penalties
- Foundation Gamma owes an excise tax of $1,000 but misses the payment deadline by 3 months.
- Penalty Calculation:
- Monthly Penalty: 0.5% of $1,000 = $5 per month.
- Total Penalty for 3 Months: $5 × 3 = $15.
- Interest:
- Interest is also charged on the unpaid tax for those 3 months at the rate specified in I.R.C. Section 6621.
Example 4: Penalty Waiver Due to Reasonable Cause
- Foundation Delta couldn’t pay its excise tax on time due to a natural disaster that disrupted operations.
- Action:
- Provides documentation to the IRS explaining the circumstances.
- Outcome:
- The IRS may waive the late payment penalty, but interest on the unpaid tax will still apply until it’s paid.
Key Points to Remember
- Threshold for Estimated Payments: If your foundation’s excise tax is $500 or more, quarterly estimated payments are required.
- Avoiding Penalties: Pay taxes on time to prevent penalties and interest charges.
- Penalty Waivers: If unforeseen events prevent timely payment, communicate with the IRS and provide evidence to potentially waive penalties.
- Interest Charges: Regardless of penalties, interest will accrue on unpaid taxes until they are paid in full.
