1031 Exchange in Maryland: How Investors Defer Taxes

If you own a rental or investment property in Montgomery County and you're thinking about selling, the tax bill can be the thing that stops you cold. Between federal capital gains, depreciation recapture, and Maryland's own withholding at closing, a profitable sale can hand a large share of your equity to the government before you ever reinvest a dollar. A 1031 exchange in Maryland is the tool that lets you keep that money working.

Here's how it works in practice, what the deadlines are, and the one Maryland form that trips up out-of-state owners every single year.

What a 1031 exchange in Maryland actually does

A 1031 exchange — named after Section 1031 of the tax code — lets you sell one investment property and roll the proceeds into another "like-kind" property without paying tax on the gain at the time of sale. You're not erasing the tax. You're deferring it, potentially for decades, and potentially forever if you hold the replacement property until you pass it to heirs, who receive it at a stepped-up basis.

A 1031 exchange in Maryland defers three separate taxes that would otherwise hit you at settlement:

• Federal capital gains tax — generally 15% or 20% for most investors, depending on your income.
• Depreciation recapture — taxed at a flat 25% on all the depreciation you've claimed over the years. This one surprises people. Even if your property barely appreciated, years of depreciation deductions create a taxable amount the moment you sell.
• Maryland's nonresident withholding — money the state holds back at the closing table if you no longer live in Maryland. More on this below, because it's the piece most owners forget.

"Like-kind" is far broader than most people expect. Almost any U.S. real estate held for investment or business use is considered like-kind to almost any other. You can exchange a Bethesda rental condo for a duplex in Silver Spring, raw land in Frederick County, or a commercial building in another state entirely. What you can't do is exchange the home you live in — that's governed by a different part of the tax code. If you're selling your primary residence, the rules around the capital gains tax when you sell your primary home are what apply, not Section 1031.

The two deadlines that make or break your exchange

The exchange lives or dies on two clocks, and both start the day your sale closes:

1. 45 days to identify. You have 45 calendar days from closing to name your replacement property in writing — signed and delivered to your qualified intermediary, not your agent or attorney.
2. 180 days to close. You must complete the purchase of the replacement property within 180 calendar days of the original sale. The two periods run at the same time, so the 45 days come out of the 180.

These deadlines are absolute. They don't extend for weekends or holidays, and the IRS does not grant do-overs. If day 45 lands on a Sunday, you still identify by that Sunday.

When you identify, you follow one of three rules:

• Three-property rule — identify up to three properties of any value. Most investors use this one.
• 200% rule — identify any number of properties as long as their combined value doesn't exceed 200% of what you sold.
• 95% rule — identify as many as you want, but you have to close on at least 95% of the total value you named.

The other non-negotiable piece is the qualified intermediary. This is an independent third party who holds your sale proceeds for the entire exchange. You can never take possession of the money. If the check hits your bank account — even for a day — the exchange is dead and the full tax comes due. You line up the intermediary before you close, never after.

To fully defer the tax, two things have to be true: you reinvest all of the net proceeds, and you buy a property of equal or greater value. Any cash you pull out, or any drop in value, is called "boot" — and boot is taxable. In a partial exchange, that boot gets taxed as depreciation recapture first, at that 25% rate, before capital gains.

A quick example. Say you sell a Bethesda rental for $900,000 and clear $400,000 in net proceeds after paying off the loan and closing costs. If you reinvest the full $400,000 into a replacement property worth at least $900,000, you defer everything. If you instead keep $50,000 in your pocket, that $50,000 is boot — and you'll pay tax on it now, starting with recapture.

Maryland's nonresident withholding — and the form that waives it

This is where Maryland adds a wrinkle the federal rules don't. If you've moved out of state — say you relocated for work but kept your Bethesda rental — Maryland treats you as a nonresident and withholds tax on the sale right at closing. As of January 1, 2026, that rate is 8.75% of the net proceeds for individuals, and 8.25% for entities like an LLC.

On a property with $400,000 of net proceeds, that's $35,000 the state holds back — even though a properly structured exchange means you don't owe the tax yet.

Maryland does recognize 1031 exchanges and will waive the withholding, but only if you ask in advance. You file Form MW506AE, the Application for Certificate of Full or Partial Exemption, with the Comptroller of Maryland at least 21 days before settlement, and your qualified intermediary submits a cover letter confirming the exchange is underway. Miss that 21-day window and the state withholds the money anyway. You'd get it back eventually, but only after filing a Maryland return the following year — a five-figure sum tied up for a year for no reason.

The point to remember: the Maryland exemption is a paperwork deadline stacked on top of the federal ones. Your intermediary and your closing attorney need to be coordinating on it weeks before you sit down at the table, not the morning of.

When a 1031 exchange in Maryland makes sense — and when it doesn't

An exchange is a powerful tool, but it isn't automatic. It tends to make sense when:

• You've held the property long enough to owe meaningful depreciation recapture and gains.
• You want to stay invested in real estate — trading up, consolidating several small units into one larger building, or shifting equity into a stronger rental market.
• You already have a realistic replacement property in mind before you list, so the 45-day clock isn't a frantic scramble.

It makes less sense if you actually want to cash out and walk away, if your gain is small, or if you can't find a replacement property you'd genuinely want to own for its own sake. Forcing a bad purchase just to beat a deadline is how investors end up with a worse asset and the same eventual tax bill.

There's also the question of what you're selling. If your rental has renters in place, the timing of the exchange has to line up with the lease terms and Maryland's notice rules — the same issues that come up any time you're selling a home with tenants in Maryland. And before you commit either way, it's worth running the real numbers on what you'll actually net from the sale — once with the exchange, and once if you simply sold and paid the tax.

This is exactly the kind of decision I walk investor clients through before we list. The exchange mechanics themselves are handled by your qualified intermediary and your tax advisor, but the real estate side — pricing the property you're selling, finding and timing the replacement purchase inside the 45- and 180-day windows, and coordinating the Maryland exemption — is where a local agent earns their keep. It's smart to loop in a Maryland real estate attorney early too, since the exemption paperwork and the exchange documents have to be right the first time.
