Identify replacements before day 45

A worksheet, not an exchange. List the building you are selling and up to three replacements. CompNinja values each one. A qualified intermediary has to receive the written list by day 45 — this page is not that list.

1031 identification worksheet

Addresses stay in your browser until you choose to value one. Copying the link puts the worksheet in the page address after the #, which is not sent to our servers.

What you are selling

When the clock starts

Calendar days, no extensions assumed. The 180-day period can end sooner if your tax-return due date arrives first and you do not file an extension — confirm your dates with your tax advisor.

Up to three replacements

Most exchanges identify three properties of any value. You type the addresses; CompNinja does not pick them.

This is not a written identification and not a 1031 exchange. Deliver the signed list to your qualified intermediary. CompNinja does not send it for you.

What a 1031 exchange is

When you sell investment or business real property and reinvest the proceeds in other like-kind real property, section 1031 of the tax code lets the capital-gains tax be deferred rather than paid now. Like-kind is broad for real estate — an industrial building for a retail center is fine. Since the 2017 tax law took effect, only real property qualifies. The tax is deferred, not erased: the gain rolls into the new property's basis.

The workflow, in order

  1. Know what the building is worth before you list

    A defensible asking price starts the whole timeline on the right foot. Use the worksheet above, then run a free valuation — an automated estimate built from real comparable sales, not an appraisal.

  2. Engage a qualified intermediary before closing

    The QI holds your sale proceeds. Touch the money yourself and the exchange generally fails — this is the step that cannot be fixed after the fact.

  3. Close the sale — the clock starts

    Both deadlines below count calendar days from this closing date. Weekends and holidays do not extend them.

  4. Identify replacements in writing within 45 days

    A signed, unambiguous list of candidate properties delivered to your QI. The worksheet on this page is not that list. The identification rules below limit how many and how much.

  5. Close on the replacement within 180 days

    The purchase of the identified property must complete within 180 days of your sale (or by your tax-return due date, if that comes first and you do not extend).

  6. Report it on your return

    The exchange is reported on IRS Form 8824 for the year of the sale. Keep the QI agreement and both closing statements together for your tax preparer.

The identification rules

Within the 45 days you may identify, in writing:

  • Up to three properties of any value (the three-property rule) — the route most exchanges take; or
  • Any number of properties whose combined value stays within 200% of what you sold (the 200% rule); or
  • More than that only if you actually acquire 95% of the value you identified (the 95% rule — rarely used on purpose).

Common ways exchanges fail

  • Touching the proceeds. The money must go from closing to the qualified intermediary, never through your account.
  • Missing the written identification. Day 45 needs a signed list delivered to the QI, not an intention.
  • Boot. Leftover cash, or debt you do not replace, is taxable even when the exchange otherwise succeeds.
  • Specialist variations. Reverse exchanges (buy first) and improvement exchanges exist, but they need specialist QIs and more structure — get advice early.

Choosing a qualified intermediary

The QI is the one professional every delayed exchange must have, and the industry is lightly regulated — your sale proceeds sit with whoever you pick. CompNinja is not a qualified intermediary and does not hold funds. Before your sale closes, verify these about anyone who will:

Where to find one: your closing attorney, title or escrow officer, and CPA all see intermediaries' work firsthand. And when CompNinja connects you with a local broker for an opinion of value, ask them which intermediaries their clients use in your market — brokers watch these deals close.

Questions owners actually ask

What is a 1031 exchange?

A section 1031 exchange (named for its section of the U.S. tax code) lets an owner defer capital-gains tax when selling investment or business real property, by reinvesting the proceeds into other like-kind real property under strict rules and deadlines. The tax is deferred, not forgiven — the gain carries into the replacement property.

Does my property qualify?

Real property held for investment or productive use in a trade or business generally qualifies — an industrial building, an office, a retail center, land. A primary residence does not, and since the 2018 tax-law changes, personal property (equipment, vehicles, franchises) no longer qualifies at all.

What is a qualified intermediary, and why before closing?

A qualified intermediary (QI) is an independent party who holds the sale proceeds between your sale and your purchase. If you receive the proceeds yourself — even for a day — the exchange generally fails and the gain becomes taxable. The QI must be engaged before your sale closes; there is no fixing it afterward.

Is this page the written identification I give my QI?

No. This page is a worksheet so you can line up the buildings and the dates. The written identification has to be a signed list delivered to your qualified intermediary by day 45. CompNinja does not send anything to a QI, and this worksheet is not that list.

What happens if I miss the 45-day or 180-day deadline?

The exchange fails and the deferred gain generally becomes taxable. Both deadlines are counted in calendar days from the closing of your sale, and they are not extended for weekends or holidays. The 180-day period can also end earlier if your tax-return due date arrives first and you do not extend.

What is boot?

Any non-like-kind value you receive in the exchange — leftover cash, or debt on the old property that is not replaced on the new one. Boot does not sink the exchange, but it is taxable up to your gain. Trading down in price or equity usually creates boot.

Do I have to reinvest everything?

To defer the full gain, the replacement property generally needs to be of equal or greater value and you need to reinvest all the equity. Reinvesting less still works as a partial exchange, with the difference taxed as boot.

Where does the exchange get reported?

On IRS Form 8824, filed with the federal return for the year of the sale. Your tax preparer handles the mechanics; what they need from you is the timeline, the QI paperwork, and the closing statements from both legs.

How do I choose a qualified intermediary?

Verify five things before your sale closes: your funds will sit in a segregated qualified escrow or trust account in your name, never commingled; a fidelity bond and errors-and-omissions insurance are in force, with certificates you can see; the QI is registered in states that regulate exchange facilitators, if yours does; they are independent of you (not your own agent, attorney, or accountant from the last two years); and the fees are in writing, including who keeps the interest earned on your money while they hold it. Your closing attorney, title officer, and CPA all see intermediaries' work firsthand and can point you to established ones.

How much does a qualified intermediary cost?

A straightforward delayed exchange typically runs from several hundred dollars to around $1,500 in stated fees, and many intermediaries also keep some or all of the interest earned on your escrowed funds while they hold them — ask about both numbers and get them in writing. Reverse and improvement exchanges are specialist work and cost several times more.

Can my own attorney or CPA act as my qualified intermediary?

Generally not: the rules disqualify anyone who has been your employee, attorney, accountant, investment banker, or real estate agent within the two years before your sale. The intermediary has to be independent — your attorney and CPA still advise you alongside them, which is exactly the arrangement you want.
