Washington State Real Estate Excise Tax (REET) Triggers in Controlling Interest Transfers

When buying or selling a business in Washington State, many entrepreneurs focus entirely on the purchase price and operational transitions. However, if the target company owns real estate-whether it is a warehouse in Seattle, an office building in Bellevue, or agricultural land in Yakima-a major hidden cost often lurks in the shadows: the Real Estate Excise Tax (REET). The state strictly taxes the transfer of a "controlling interest" in any entity holding local real property. If you do not properly structure your mergers and acquisitions (M&A) deals, you could be hit with a surprise tax bill that derails the entire transaction.

Understanding the 36-Month Lookback Rule

The core of the REET trigger lies in the definition of a "controlling interest" transfer. Under Wash. Rev. Code § 82.45.033, a controlling interest means the transfer of 50% or more of the voting stock in a corporation, or 50% or more of the capital, profits, or beneficial interest in a partnership, LLC, or trust. Importantly, Washington applies a strict 36-month lookback period. This means the Washington State Department of Revenue, Olympia will aggregate all partial transfers made over any 36-month span. If you sell 25% of an LLC in January and another 25% two years later, the second sale triggers REET on the true and fair value of the underlying real estate.

Commercial Property Holding Companies

Many commercial real estate investors in Tacoma and Spokane hold properties in single-purpose LLCs. When investors sell the LLC rather than the deed to the property itself (often to avoid standard deed recording taxes), Washington law pierces this veil. If 50% or more of the LLC changes hands, REET is calculated based on the assessed or appraised value of the commercial building, not just the purchase price of the LLC shares. This prevents entities from dodging REET through stock transfers.

Agricultural Land Entities

Washington has a massive agricultural sector. When generational farms or agribusinesses in Eastern Washington are sold, they are often structured as corporate buyouts. If the farming corporation owns massive tracts of land, the controlling interest transfer will trigger REET. However, there are very specific, narrow exemptions for familial transfers or corporate reorganizations that do not change the ultimate beneficial ownership, which were litigated heavily in cases like McFreeze Corp. v. Department of Revenue, 102 Wash. App. 196 (WA Court of Appeals 2000).

Multi-Family Syndications

Real estate syndicators pooling money to buy apartment complexes in Seattle must be extremely careful. When bringing on new equity partners or buying out initial investors, crossing that 50% threshold within a 36-month window will trigger the tax. Syndicators must track the exact percentage of capital interest transferred at every stage of the investment lifecycle.

Step-by-Step Process for Reporting and Paying REET

If your transaction triggers REET, Washington State requires strict adherence to reporting and payment timelines. Under Wash. Admin. Code § 458-61A-101, the tax return must be filed within five days of the transfer, and the tax must be paid within one month (30 days) to avoid delinquent penalties under Wash. Rev. Code § 82.45.100.

Step 1: Calculate the True and Fair Value

You must determine the value of the real estate owned by the entity. This is usually done using the county property tax assessment or a certified independent appraisal. REET in Washington is progressive, with rates increasing as the property value climbs, plus local city/county REET rates.

Step 2: Complete the Required Form

The seller (or sometimes the buyer, depending on the agreement) must file the official tax return. You will need to complete Form 84-0001b, Washington, Department of Revenue, Controlling Interest Transfer Return. This form requires detailed information about the entity, the buyers, the sellers, and the properties involved.

Step 3: File with the State

Unlike traditional real estate sales where REET is paid to the county treasurer (like the King County Treasurer, Seattle), controlling interest REET must be filed directly with the Washington State Department of Revenue, Olympia. This can be done online through the My DOR portal or via certified mail.

Step 4: Pay the Tax and Retain Records

Pay the calculated tax within 30 days of the transaction closing date. It is critical to keep copies of the stock purchase agreement, the REET return, and proof of payment for at least five years, as controlling interest audits are incredibly common in Washington.

How Much Does it Cost in Washington?

The financial impact of REET can be massive. State REET rates operate on a graduated scale based on the selling price or value of the property:

• State Rates: Usually ranges from 1.1% on the lowest tier up to 3.0% on the portion of the value over roughly $3 million (exact thresholds adjust periodically).
• Local Rates: Cities and counties add their own REET, typically ranging from 0.25% to 0.75%. In Seattle, the combined state and local rate for high-value properties can push near 3.5% or more.
• Filing Penalties: Late filing incurs a 5% penalty per month, up to 20% of the tax due, plus interest.
• Attorney Fees: Hiring an M&A or real estate lawyer to structure the deal and handle compliance typically costs between $3,000 and $10,000 depending on complexity.

How Long Does the Process Take?

Identifying the REET liability should happen during the due diligence phase, which takes 30 to 60 days before closing. Once the controlling interest transfer occurs, you have five days to file the Form 84-0001b, Washington, Department of Revenue, Controlling Interest Transfer Return and one month (30 days) to pay the tax to avoid delinquent penalties. If the DOR audits the transaction, the review process can take 3 to 6 months to resolve.
