Missouri 1031 exchange: Rules and tips

What is a 1031 exchange?

A 1031 exchange in Missouri is a federal tax-deferral strategy that lets an investor sell one investment (or business-use) property and reinvest the proceeds into another qualifying property without paying federal income tax on the gain at the time of sale.

It’s governed by Section 1031 of the U.S. Internal Revenue Code and administered by the IRS. Missouri generally follows the federal 1031 framework for state income tax purposes.
 

Key requirements for a 1031 exchange

1. The property must qualify

   Both the property being sold and the one being purchased must be held for business or investment purposes. A primary residence does not fit within the rules.
    

2. A qualified intermediary must hold the funds

   The investor cannot receive or control the sale proceeds. A qualified intermediary (QI) holds the money between the sale and the purchase. If the investor touches the funds, the exchange is usually invalid.
    

3. The 45-day deadline to identify replacement property

   Within 45 days after the sale closes, the investor must formally identify potential properties they may buy. The list must be in writing and follow IRS identification rules. Investors are commonly allowed to identify up to three possible replacement properties under the standard identification rule.
    

4. The 180-day timeline to complete the purchase

   The replacement property must be purchased within 180 days of the sale of the original property, or by the due date of the investor’s tax return for that year (including extensions), whichever comes first. The 45-day and 180-day windows run at the same time, not one after the other.
    

5. Matching the replacement property to the identification list

   The investor must purchase a property that appeared on their written identification list. Changing or adding properties after the 45-day deadline is generally not allowed.
    

6. Documentation needed for a valid exchange

   The exchange agreement, identification notices, closing statements, and intermediary documents need to fit IRS rules. A tax professional usually helps confirm that the paperwork supports the exchange.

Lower-value property exchanges

If the replacement property costs less than the one you sold or you keep part of the sale proceeds, the leftover amount may be taxable. This is often called “boot.” Boot can also come from credits or non-real-estate items on the closing statement. Because small details can change the tax result, most investors have their qualified intermediary and CPA review the figures before the exchange closes.
 

Property types

Most 1031 exchanges involve investment real estate such as:

• Single-family rentals
   
• Small multifamily properties
   
• Larger apartment buildings
   
• Retail/office/industrial property
   
• Raw land held for investment

Common examples that are typically not eligible include a primary residence, property you’re holding primarily for resale (a “flip”), and partnership interests. Your tax advisor can help confirm how your use and intent affect eligibility.
 

The 200% rule

The 200% rule lets an investor list more than three possible replacement properties as long as the combined value of those properties is no more than twice the value of the property that was sold. This rule is helpful when you want extra options or are looking at several smaller properties, as long as the total value stays within the allowed limit.
 

The role of a qualified intermediary (QI)

For most 1031 exchanges, a qualified intermediary is the “middle person” who helps structure the exchange so the sale proceeds don’t go into your control. The QI receives the funds from the sale, holds them, and then uses them to buy the replacement property on your behalf.
 

Who cannot be a QI?

Your QI cannot be anyone who served as your employee, attorney, accountant, investment banker/broker, or real estate agent/broker at any time in the two years before you transfer your first relinquished property, except for limited routine title, escrow, or banking-type services. This matters because a 1031 exchange generally fails if you or someone acting as your agent can access the money before the replacement purchase closes.
 

Missouri generally has no real estate transfer tax

Unlike many states, Missouri does not impose a state or local real estate transfer tax in the way “deed stamp” states do. Missouri’s Constitution prevents the state and political subdivisions from imposing any new tax on the sale or transfer of homes or other real estate. That said, closing still includes costs such as title insurance, escrow/title fees, and recording fees.
 

Recording fees vary by county

Recording fees are set by Missouri law and layered with state/county allocations, so what you pay at closing can vary by county and by whether your document meets formatting standards. For example:

• St. Louis County lists deed recording costs of $24 for the first page and $3 for each additional page, plus a $25 non-standard fee if the document doesn’t meet Missouri document formatting standards.
   
• Jackson County shows a standard recording fee of $21 for the first page and $3 for each additional page.
   
• Missouri statute also reflects a per-page structure for recording instruments (with fees allocated to various funds and local offices).

A 1031 exchange can defer income taxes, but recording/closing fees still apply, and board members and owners should budget for them.
 

Missouri’s new capital gains rules for 1031 exchanges

Beginning January 1, 2025, Missouri allows individuals to deduct all federally reported capital gains when calculating their Missouri adjusted gross income under Mo. Rev. Stat. § 143.121. This includes gains from real estate. In practice, many individual sellers may now owe little or no Missouri state income tax on capital gains even if they do not complete a 1031 exchange.

A 1031 exchange can still be helpful because it defers federal capital gains tax and gives the investor more reinvestment power, but the state-level benefit may be smaller than it was in the past. Because this area is evolving, it is wise to ask your CPA how the updated Missouri rules apply to your situation.
