The Treasury Department and the IRS published TD 10048 in the Federal Register on May 20, 2026. The final rule lets a partnership send investors only Parts I to III of Form 8308 by January 31. The detailed gain figures in Part IV now travel with the Form 1065 and the Schedule K-1. For a real estate syndication, the rule is a reminder that one investor's sale creates a federal reporting duty for the partnership itself. Statements for interests that changed hands in 2026 are due by January 31, 2027, or 30 days after the partnership learns of the exchange if that is later.
When an investor sells or assigns an interest before the property is sold, the transaction can be a section 751(a) exchange. The duty to report it falls on the partnership, not on the departing investor. A sponsor that builds transfers into its operating agreement and its calendar for the end of the year handles them as routine administration. A sponsor that treats them as private deals between investors risks missed forms and penalties. Our guide to real estate fund administration explains where this work sits in a sponsor's back office.
What Form 8308 Reports and Why Real Estate Partnerships Trigger It
Section 751 of the Internal Revenue Code treats part of the gain on a sale of a partnership interest as ordinary income when the partnership holds hot assets. These are unrealized receivables and inventory items. The IRS instructions for Form 8308 say a section 751(a) exchange occurs when money or property is exchanged for an interest attributable to those assets. The definition reaches real estate because Section 751(c) pulls depreciation recapture into it. Section 1245 property and section 1250 property count as unrealized receivables to the extent of the recapture gain a sale at fair market value would produce.
A partnership that owns buildings and land therefore cannot assume it holds no hot assets. Depreciation on section 1245 property can produce recapture under Section 1245(a), and depreciation on buildings can produce recapture under Section 1250(a). For that reason, a sponsor's CPA should test each transfer rather than wait for a sale of the property. Part IV of Form 8308 also asks for collectibles gain under Section 1(h)(5) and unrecaptured section 1250 gain under Section 1(h)(6). For each category, the partnership reports its own gain on a hypothetical sale and the departing partner's share of it.
Who Files Form 8308 and When the Duty Starts
The partnership files a separate Form 8308 for each section 751(a) exchange. The form is attached to the Form 1065 and is due with that return, including extensions, under the IRS instructions revised in November 2025. The duty starts once the partnership has notice of the exchange. Notice can come from a written statement by the transferor, or from the partnership's own knowledge that an interest changed hands while it held section 751 property. The partnership may rely on a written statement from the transferor that no section 751(a) exchange took place, unless it knows otherwise.
The investor has a deadline as well. Under the Treasury regulation for Section 6050K, the transferor must notify the partnership in writing within 30 days of the exchange or by January 15 of the following year, whichever is earlier. The notice gives both parties' names and addresses, the transferor's taxpayer identification number and the date of the exchange. It also gives the transferee's number if known. Penalties apply under Section 6722 for a missed notice or statement, and under Section 6721 for a partnership that fails to file the form.
What the May 2026 Rule Changed for Form 8308 Statements
Before TD 10048, the partnership had to give the transferor the information for the transferor's own statement on the gain. In practice that meant the Part IV figures by January 31. Those figures depend on a hypothetical sale of the partnership's property at fair market value, which takes time to prepare. The IRS had already granted relief in Notice 2024-19. The final rule, adopted without change from the proposal of August 19, 2025, applies to returns filed for taxable years ending on or after May 20, 2026.
The statement to the transferor and the transferee is still due by January 31 of the year after the exchange, or 30 days after notice if later. It now needs only Parts I to III. The Part IV amounts have not gone away, because the partnership still attaches a complete Form 8308 to its Form 1065. It also reports the transferor's share in box 20 of the Schedule K-1 using codes AB, AC and AD. The detailed numbers therefore reach the departing investor with the K-1, which ties Form 8308 to the planning covered in our article on Form 1065 extensions and late syndication K-1s.
Transfers by Investors Abroad Add a Withholding Step
A transfer by a foreign partner brings a second rule into play. Under Section 1446(f), the IRS says the buyer of a partnership interest must withhold 10 percent of the amount realized when gain would be effectively connected with a U.S. trade or business. If the buyer fails to withhold, the partnership must withhold the missed amount, plus interest, from distributions to that buyer. Form 8308 has a box in Part I for a foreign transferor. The instructions also send the Part IV figures for foreign transferors to Schedule K-3.
Structure decides whether this step arises at all. Where offshore investors hold through a U.S. C corporation blocker, the blocker is the partner. An investor abroad who sells shares of the blocker is therefore not transferring an interest in the partnership. Investors who hold directly are partners, and their transfers need a withholding review before closing. Our guide to international investors in a U.S. real estate syndication compares the two routes, and the guide to Forms 8804, 8805 and 1042-S covers the annual reporting that follows.
What Sponsors Can Do Before the January 31 Deadline
The most useful work happens before any investor asks to sell. A sponsor can review its operating agreement with securities counsel so that every transfer needs the manager's written consent. That gives the partnership notice by design. Consent also lets counsel confirm that the buyer and the transfer fit the terms of the original offering. With those terms in place, each transfer can follow the same steps in the same order.
- Collect the written notice the regulation requires from every transferring investor, with names, addresses, taxpayer identification numbers and the exchange date.
- Ask the partnership's CPA to test whether the partnership held section 751 property on the transfer date.
- Send Parts I to III of Form 8308 to both parties by January 31, or within 30 days of notice if that is later.
- Carry the Part IV figures into the Form 1065 filing and box 20 of the transferor's Schedule K-1.
- For a foreign transferor, agree before closing who will handle the Section 1446(f) withholding.

See how the Raveum Sponsor Program works.
A Transfer Is a Tax Event for the Partnership Too
TD 10048 eased a deadline the IRS had already relaxed by notice, but it left the core obligation in place. When an interest changes hands, the partnership must learn of it, test it, report it and carry the numbers into the K-1. In a deal with investors abroad, it may also need to account for withholding. Sponsors who treat transfers as part of fund administration, with consent rights, a standard notice form and a checklist for the end of the year, keep Form 8308 from being missed. The guide to real estate fund administration shows how that work fits alongside K-1 preparation and investor reporting.
Frequently Asked Questions
What Is Form 8308 Used For?
Form 8308 reports a section 751(a) exchange, the sale or exchange of a partnership interest when the partnership holds unrealized receivables or inventory items. In real estate, depreciation recapture on section 1245 and section 1250 property can count as unrealized receivables. The partnership files the form with its Form 1065 and sends statements to the buyer and seller of the interest.
Who Files Form 8308 in a Real Estate Syndication?
The partnership files it, not the investor who sold. The investor's job is to notify the partnership in writing within 30 days of the exchange or by January 15 of the following year, whichever is earlier. Once the partnership has notice or knowledge of the transfer, it must file a separate Form 8308 for each section 751(a) exchange.
When Is the Form 8308 Statement Due to the Buyer and Seller?
The statement is due by January 31 of the year after the exchange, or 30 days after the partnership has notice of it if that is later. Under the final rule published on May 20, 2026, the statement needs only Parts I to III. The Part IV figures go with the Form 1065 and box 20 of the seller's Schedule K-1.
Does a Gift of a Partnership Interest Require Form 8308?
The IRS instructions say a gift of a partner's entire interest is not a section 751(a) exchange, because no money or property is exchanged for it. Other transfers, including partial sales and assignments for value, can be exchanges if the partnership holds section 751 property. A sponsor should have its CPA review any transfer that involves consideration of any kind.
What Happens if a Partnership Does Not File Form 8308?
The partnership can face penalties under Section 6721 for failing to file a correct Form 8308 and under Section 6722 for failing to furnish statements to the buyer and seller. The IRS instructions also cite Sections 6698 and 6724, and penalties may be waived for reasonable cause. A sponsor should ask its CPA and tax counsel to review any missed filing promptly.
Does a Foreign Investor's Sale of a Syndication Interest Need Withholding?
Often, yes. Under Section 1446(f), the buyer of an interest from a foreign partner must withhold 10 percent of the amount realized when gain would be effectively connected with a U.S. trade or business, unless an exception applies. If the buyer does not withhold, the partnership must withhold from the buyer's distributions. Investors abroad who hold through a blocker corporation are not partners themselves.
