Form 990 Schedule R is the attachment full-Form 990 filers use to disclose their related organizations, certain transactions with those organizations, and any unrelated partnerships through which they conduct significant activity. It has six parts, and you complete only the parts triggered by your “Yes” answers on Form 990, Part IV. If you file Form 990-EZ or Form 990-N, Schedule R does not apply to you.
When You Have to File Schedule R
Schedule R is not automatically attached to every Form 990. The checklist in Form 990, Part IV tells you what to complete:
- Line 33 (disregarded entities) triggers Part I.
- Line 34 (related organizations) triggers Parts II, III, IV, and Part V line 1, as applicable.
- Line 35b (payments from or transactions with controlled entities) triggers Part V, line 2.
- Line 36 (transfers to exempt non-charitable related organizations) triggers Part V, line 2. This one applies only to Section 501(c)(3) organizations.
- Line 37 (activity conducted through an unrelated partnership) triggers Part VI.
Answer “No” to all of them and you skip Schedule R entirely. If you voluntarily file a full Form 990 when you were not required to, you still complete every applicable schedule, Schedule R included.
What Counts as a Related Organization
An organization is related to yours if it fell into a defined relationship category at any time during the tax year. Even a single day of qualifying relationship counts.
Parent, Subsidiary, and Brother/Sister
Most relationships come down to control. A parent controls your organization. A subsidiary is one your organization controls. Brother/sister organizations arise when the same person or group controls both your organization and another entity.
For entities with owners (corporations, partnerships, LLCs, trusts), control means more than 50 percent of the voting stock or value of a corporation, more than 50 percent of the profits or capital interest in a partnership or LLC, or more than 50 percent of the beneficial interests in a trust. For nonprofit organizations, control means the power to appoint or remove a majority of the other organization’s directors or trustees.
Constructive Ownership
Direct ownership isn’t the whole test. The IRS requires you to apply the constructive ownership rules of IRC Section 318 for corporations, and similar principles for partnerships and trusts. Ownership held by a subsidiary is attributed up to the parent proportionally. If your organization owns 80 percent of a taxable corporation, and that corporation holds a 70 percent profits interest in a limited partnership, your organization is treated as owning 56 percent of the partnership. Both entities are related organizations you must report.
Family attribution also applies. Stock owned by a spouse, children, grandchildren, or parents can be attributed to an individual when determining control. These rules catch layered structures and family arrangements that would otherwise sit outside the direct-ownership test.
Supporting Organizations and VEBAs
Organizations classified under IRC Section 509(a)(3) as supporting organizations count as related regardless of any ownership threshold. Type I organizations are operated, supervised, or controlled by the supported organization; Type II are supervised or controlled in connection with it; Type III are operated in connection with it.
For a voluntary employees’ beneficiary association (VEBA) under Section 501(c)(9), the sponsoring organization that establishes or maintains the VEBA is a related entity, as is any employer contributing to the VEBA during the tax year.
Part I: Disregarded Entities
Part I lists entities that are legally separate from your organization but ignored for federal tax purposes, most often a single-member LLC that has not elected corporate treatment. The disregarded entity’s income, expenses, assets, and liabilities already flow onto your Form 990, but you still identify the entity here so the IRS can see the structure.
For each disregarded entity you report the legal name, address, and EIN (if any); the primary activity; the legal domicile (state or foreign country); the total income and end-of-year assets attributable to the entity (carved out of your Form 990 totals, not new numbers); and the direct controlling entity.
Parts II, III, and IV: Related Organizations by Tax Treatment
These three parts collect identifying information about related organizations, sorted by how each entity is taxed. The IRS cross-references what you report here against each related entity’s own filings, so putting an entity in the wrong Part causes real problems.
Part II: Related Tax-Exempt Organizations
Part II covers related organizations that are themselves tax-exempt. You provide name, address, EIN, primary activity, legal domicile, the Code section under which the entity claims exemption (such as 501(c)(3) or 501(c)(6)), public charity status if it is a 501(c)(3), the direct controlling entity, and whether the related organization is a controlled entity under IRC Section 512(b)(13). That last column matters because certain payments (interest, rent, royalties, annuities) flowing from a controlled entity to your organization can be treated as unrelated business taxable income.
Part III: Related Organizations Taxable as Partnerships
Part III covers related organizations treated as partnerships for federal tax purposes. Along with the standard identifiers, you report the type of entity (general partner, limited partner, or LLC member), the related entity’s share of aggregate income and end-of-year assets, the direct controlling entity, the relationship type, your organization’s share of the partnership’s profits and capital, and any disproportionate allocations.
Part IV: Related Organizations Taxable as Corporations or Trusts
Part IV covers related taxable corporations and trusts. You report identifying data, the type of entity, total income, end-of-year assets, the direct controlling entity, your organization’s share of income, and your ownership percentage.
Part V: Transactions With Related Organizations
Part V is where the IRS looks at money moving between your organization and related entities in Parts II, III, or IV. Disregarded entities from Part I are excluded because their finances are already inside your Form 990.
Line 1 asks 19 yes/no questions covering categories such as interest, annuities, royalties, or rent from controlled entities; grants and contributions in either direction; loans and loan guarantees; sales, purchases, or exchanges of assets; leases of facilities or equipment; performance of services, fundraising, and membership solicitations; sharing of facilities, equipment, mailing lists, or paid employees; expense reimbursements; and any other transfer of cash or property, including mergers. For each “Yes,” line 2 asks for the related organization’s name, the transaction type, the amount, and the method used to determine that amount.
The “method of determining amount involved” column is where shared-service arrangements draw scrutiny. If your organization centralizes accounting, human resources, office space, or staff for related entities, the allocated cost has to reflect a reasonable, consistently applied method. The IRS is looking for arm’s-length terms. Providing free office space to a related for-profit, for example, is a reportable transaction, and you’ll need a defensible valuation for it.
Part VI: Unrelated Partnerships
Part VI is different. It covers partnerships that are not related organizations but through which your organization runs a meaningful share of its activities. Report an unrelated partnership if all three of the following are true:
- The partnership is not a related organization.
- Your organization was a partner or member at any time during the tax year.
- Your organization conducted more than 5 percent of its activities through the partnership, measured by the greater of total assets or total revenue.
The 5 percent test compares your capital account balance in the partnership (asset test) or your distributive share of gross revenue (revenue test) against the corresponding total on your Form 990.
There is an exception for passive investments. You can disregard an unrelated partnership if 95 percent or more of your revenue from it is investment income (interest, dividends, royalties, rents, and capital gains) and your primary purpose in the investment is income production or property appreciation rather than carrying out a charitable activity.
Penalties for Incomplete or Late Filing
Schedule R is part of your Form 990, so an incomplete Schedule R means an incomplete Form 990. Under IRC Section 6652(c)(1)(A), the penalty for a late or incomplete Form 990 is $20 per day, capped at the lesser of $10,000 or 5 percent of gross receipts for the year. Organizations with gross receipts over $1,000,000 face $100 per day, capped at $50,000.
The penalty applies to on-time returns that are missing required information, not just late returns. Leaving a clearly related organization off Schedule R can trigger the incomplete-return penalty even if the rest of the return is clean, and it accrues until the missing information is provided. If you receive a penalty notice, you can request abatement by showing reasonable cause; the IRS evaluates these case by case based on whether the organization exercised ordinary business care and prudence.
Common Mistakes to Avoid
The most frequent error is simply missing a related entity. Layered subsidiaries, shared board members, and constructive-ownership chains all produce related organizations that are easy to overlook. Before completing Schedule R each year, map every entity connected to yours and apply both the direct and constructive ownership tests. An entity that was related for only part of the year still gets reported.
Putting the right entity in the wrong Part is the next most common problem. A related LLC taxed as a partnership goes in Part III, not Part II. A single-member LLC that is disregarded goes in Part I. Misclassifying the tax treatment cascades into wrong data fields and often draws follow-up correspondence from the IRS.
On Part V, organizations frequently underreport shared services and below-market arrangements. If your nonprofit lets a related entity use office space, equipment, or staff without charging full value, that is a reportable transaction. Failing to report it, or reporting it without a defensible valuation, is exactly what the IRS is scanning for when it looks for exempt resources subsidizing non-exempt entities.
