Form Overview

IRS Form 990-SI - 990 (Schedule I)

Form 990‑SI (Schedule I) is the supplemental schedule that reports a tax‑exempt organization’s investments and other assets. It must be attached to the annual Form 990 when the organization holds $500,000 or more in investments or other specified assets.

It captures the fair‑market value of stocks, bonds, mutual funds, real estate, and other investment‑type assets at year‑end, plus any related income and expenses.

  • 3Leaving out any asset class required on Schedule D
  • 4Mismatched totals between Schedule I and Schedule D
  • 5Failing to sign the schedule

Plain English

Schedule I tells the IRS how much a nonprofit’s investments, like stocks, bonds, and real estate, are worth. If the nonprofit’s investment portfolio is big enough, the IRS requires this extra schedule with the regular 990 filing.

Check the organization’s most recent Form 990 to see whether Schedule I was attached. If the prior year’s filing included Schedule I, the organization likely meets the $500,000 threshold and must file again this year.

What changed or needs a fresh check

  • Edition date: Verify you have the 2023 revision of Schedule I (latest as of filing year).
  • Fee: No filing fee for Schedule I; only the base Form 990 filing fee applies if filing electronically.
  • Mailing address: Use the address listed in the 2023 Form 990 instructions for paper filings.
  • Electronic filing: Confirm the e‑file provider supports Schedule I attachment.
  • Signature line: Ensure the schedule includes the same authorized signature as the main 990.

Quick Facts

All tax‑exempt organizations filing Form 990 that have $500,000 or more in investments or other assets reported on Schedule D must file Schedule I.
It captures the fair‑market value of stocks, bonds, mutual funds, real estate, and other investment‑type assets at year‑end, plus any related income and expenses.
Schedule I is due the same day as the organization’s Form 990, generally the 15th day of the 5th month after the fiscal year ends (e.g., May 15 for a calendar‑year filer).
Submit the completed Schedule I as an attachment to the paper Form 990 mailed to the IRS address listed in the 990 instructions, or upload it with the electronic 990 filing through the IRS Modernized e‑File system.
Errors or omissions can trigger penalties, delay the organization’s public disclosure, and raise the risk of an audit of the organization’s financial statements.
Gather year‑end investment statements, calculate fair‑market values, fill out Part I (Investments) and Part II (Other assets), double‑check totals against Schedule D, sign the schedule, attach it to the 990, and file electronically or by mail before the deadline.

Common confusion points

Threshold amount

$500,000 applies to total investments on Schedule D, not just Schedule I

→ Verify Schedule D total first

Asset classification

Some assets (e.g., collectibles) may not belong on Schedule I

→ Review IRS asset definitions

Valuation date

Year‑end value is required, not the date of the statement

→ Use the last day of the fiscal year

Duplicate reporting

Same asset listed on Schedule I and Schedule D

→ Cross‑check both schedules

Signature requirement

Schedule I must be signed even if the 990 is signed electronically

→ Ensure signature block is completed
