Understanding Schedule D (Form 990): Supplemental Financial Statements Guide

1. Introduction – What is Schedule D (Form 990)?

Schedule D (Form 990), officially titled “Supplemental Financial Statements,” is a mandatory financial reporting schedule administered by the Internal Revenue Service (IRS), an agency of the U.S. Department of the Treasury.

It is an annual attachment to full Form 990. Tax-exempt non-profit organizations complete Schedule D to provide detailed accounting breakdowns for specialized asset and liability categories, including fixed assets, endowment funds, investments, donor-advised funds, conservation easements, and independent audit reconciliations.

2. Purpose of the Form – Why Does Schedule D Exist?

While the main Form 990 balance sheet provides high-level totals for non-profit assets and liabilities, complex organizations hold financial assets that require enhanced public and regulatory oversight.

Schedule D exists to provide granular financial transparency. It allows the IRS and the public to examine specific financial structures, verify that land and equipment are properly depreciated, confirm that endowment funds adhere to donor restrictions under uniform state laws, track museum collections or conservation easements, and reconcile independent CPA audited financial statements with tax return revenue and expense lines.

3. Who Needs to File This Form

Schedule D (Form 990) is required for organizations filing full Form 990 that answer “Yes” to any financial trigger question on Form 990, Part IV (Lines 6 through 12b). You must file Schedule D if your organization maintains any of the following:

• Donor Advised Funds (Part I): Organizations that maintain donor-advised funds or similar accounts.
• Conservation Easements (Part II): Organizations holding conservation easements, historic structure preservation rights, or open-space land protections.
• Museum & Art Collections (Part III): Organizations maintaining collections of art, historical treasures, or similar assets held for public exhibition or education.
• Escrow & Custodial Accounts (Part IV): Organizations acting as escrow agents, trustees, or holding custodial funds for third parties.
• Endowment Funds (Part V): Organizations maintaining permanent, term, or board-designated endowment funds.
• Land, Buildings, and Equipment (Part VI): Organizations reporting fixed assets on Form 990, Part X, Line 10.
• Investments & Other Assets/Liabilities (Parts VII–X): Organizations holding investments in securities, program-related investments, or reporting complex balance sheet line items (including ASC 740/FIN 48 income tax uncertainty disclosures).
• Audited Financial Statements (Parts XI & XII): Organizations that have independent CPA audited financial statements prepared for the tax year.

4. Who Is Exempt / Not Required to File

Your non-profit organization is exempt or not permitted to complete Schedule D if its filing situation falls into any of these categories:

• Form 990-EZ Filers: Small-to-mid-sized non-profits filing Form 990-EZ do not file Schedule D (even if they hold fixed assets or endowments).
• Form 990-N (e-Postcard) Filers: Small charities (gross receipts ≤ $50,000) filing Form 990-N do not submit Schedule D.
• Private Foundations: Private foundations report balance sheet details and financial assets on Form 990-PF rather than Schedule D.
• Form 990 Filers Answering “No” to Lines 6–12b: Organizations filing full Form 990 that answer “No” to all financial trigger questions in Part IV.

5. When to File

Schedule D is an annual attachment directly attached to Form 990, so it follows the exact filing deadline of the primary return.

The annual filing deadline is the **15th day of the 5th month** following the close of the organization’s accounting year (May 15 for calendar-year non-profits, or November 15 for fiscal years ending June 30). Non-profits can request an automatic 6-month filing extension by submitting Form 8868 on or before the original due date.

6. Where and How to File

Schedule D cannot be submitted as a standalone document. It must be attached directly behind Form 990 and submitted as part of your complete non-profit tax return package.

Under the Taxpayer First Act, all tax-exempt non-profit returns (including Schedule D) must be filed electronically using IRS-approved tax software. Paper submissions are no longer accepted by the IRS for standard Form 990 returns.

7. Step-by-Step Instructions to Fill the Form

Schedule D consists of 13 distinct parts that detail specific balance sheet accounts and audit reconciliations. The table below outlines the core structure of the schedule.

Form Section	Section Name	Instruction / Description
Part I & II	Donor Advised Funds & Easements	Report donor-advised fund totals and track conservation easement acreage, monitoring expenses, and enforcement staff hours.
Part III & IV	Collections & Escrow Accounts	Detail art and historical collections and disclose escrow or custodial account liabilities.
Part V	Endowment Funds	Complete a 5-year rolling grid tracking beginning balances, contributions, net investment earnings, grants, expenses, and ending balances.
Part VI	Land, Buildings, and Equipment	Itemize historical cost/basis, accumulated depreciation, and net book value for real estate, leaseholds, and equipment.
Parts VII–X	Investments & Other Items	Break down investments in securities, program-related investments, other assets, and other liabilities (including FIN 48 notes).
Parts XI & XII	Financial Statement Reconciliations	Reconcile GAAP audited revenue and expenses from independent financial audits with tax numbers on Form 990.
Part XIII	Supplemental Information	Provide required narrative explanations for endowment policies, conservation monitoring, and FIN 48 tax position disclosures.

Detailed Filling Steps

1. Report Donor Advised Funds or Easements (Parts I & II): If operating donor-advised funds, report total funds held, aggregate contributions, and ending net values. If holding land easements, report protected acreage and monitoring costs.
2. Complete 5-Year Endowment Roll-Forward (Part V): Complete the 5-year historical grid for endowment funds, tracking opening balances, new donor contributions, net investment gains/losses, grant distributions, and ending fund balances. Indicate percentages designated for permanent, term, or board-restricted funds.
3. Itemize Fixed Assets (Part VI): Detail historical cost basis and accumulated depreciation for land, buildings, leasehold improvements, and machinery. Verify that the combined net book value matches Form 990, Part X, Line 10c.
4. Itemize Investments & Liabilities (Parts VII–X): Provide detailed descriptions and valuation methods (cost vs. fair market value) for closely held stock, partnership interests, program-related investments, and other balance sheet liabilities. Include required FIN 48 / ASC 740 tax uncertainty disclosures.
5. Reconcile Audited Financial Statements (Parts XI & XII): If an independent CPA audit was performed, reconcile total GAAP revenue and expenses from the audited financial report with Form 990 Part VIII revenue and Part IX expense totals. Adjust for unrealized gains, donated services, or fundraising expenses.

8. Required Documents/Information Needed Before Filling

To ensure an accurate Schedule D submission, gather the following financial and audit records before preparing the schedule:

• Independent CPA Audited Financial Statements: Complete audited financial reports, including the balance sheet, income statement, and footnote disclosures (specifically ASC 740 / FIN 48 tax notes).
• Fixed Asset & Depreciation Schedules: Detailed asset ledgers showing original purchase cost, accumulated depreciation, and net book value for land, buildings, and equipment.
• 5-Year Endowment Ledgers: Multi-year investment statements tracking endowment opening balances, investment income, management fees, and donor spending restrictions.
• Investment Brokerage Statements: Year-end portfolio reports for publicly traded securities, alternative investments, and program-related loans.
• Conservation & DAF Agreements: Legal easement deeds, land monitoring logs, and donor-advised fund transaction records.

9. Common Mistakes to Avoid

Errors on Schedule D can lead to immediate IRS filing rejections and audit inquiries. Watch out for these frequent mistakes:

• Omitting Parts XI & XII When Audited Financials Exist: Leaving revenue and expense reconciliation schedules blank when the non-profit received an independent CPA audit.
• Mismatched Fixed Asset Totals: Entering land, building, or equipment numbers in Part VI that fail to reconcile with the main balance sheet on Form 990, Part X, Line 10c.
• Inconsistent Endowment Calculations: Submitting an endowment roll-forward in Part V where beginning balances, net returns, grants, and ending balances do not balance mathematically across all years.
• Omitting Mandatory FIN 48 Disclosures: Failing to include narrative disclosures in Part XIII regarding tax position uncertainties when audited financial statements contain FIN 48 footnote text.
• Submitting as a Standalone Return: Attempting to e-file or mail Schedule D separately without attaching it directly to Form 990.

10. Penalties for Non-Filing or Errors

Failing to file Schedule D when required carries direct financial and administrative consequences under federal non-profit law:

• Rejection of Form 990 Return: Submitting Form 990 without Schedule D when required causes the IRS to reject the return as incomplete, triggering daily late-filing penalties ($20 or $105 per day under IRC Section 6652(c)).
• Increased Audit Scrutiny: Unreconciled discrepancies between audited financial statements and Form 990 filings trigger automated IRS audit flags.
• Revocation of Tax-Exempt Status: Failing to file a complete Form 990 return (including Schedule D) for **three consecutive years** results in the automatic revocation of 501(c) tax-exempt status under IRC Section 6033(j).
