The 1031 Exchange Timeline — Every Deadline
| Day | Event | Consequence of Missing |
|---|---|---|
| Day 0 | Relinquished property closes | Clock starts {MDASH} cannot be paused |
| Days 1{NDASH}45 | 45-day ID period | Identify in writing to QI {MDASH} no extensions |
| Day 45 | ID deadline | Miss this = exchange failed, full tax due |
| Days 46{NDASH}180 | 180-day exchange period | Must acquire one identified property |
| Day 180 | Exchange completion deadline | Miss this = exchange failed (if before tax return due date) |
| Tax return due | Alternative 180-day trigger | 180 days or tax return due date, whichever earlier |
| Extension filed? | Extends 180-day deadline | File extension before return due date to get full 180 days |
The Three Identification Rules Compared
| Rule | How It Works | Use It When |
|---|---|---|
| 3-Property Rule | Identify any 3 properties regardless of value | Most transactions {MDASH} maximum flexibility |
| 200% Rule | Any number of properties, combined FMV {LEQ} 200% of sale price | Need more than 3 options |
| 95% Rule | Any number, any value {MDASH} must acquire 95% of total value | Rarely used {MDASH} extremely high compliance risk |
The 3-Property Rule is used in over 90% of 1031 exchanges. It allows flexibility (3 potential replacements) while avoiding the complexity of the 200% Rule’s math. 1031 mechanics deep dive {ARR} · 1031 by state {ARR}

FAQ
What is the 45-day rule in a 1031 exchange?
The 45-day identification rule requires that after selling the relinquished property, the investor must formally identify potential replacement properties in writing within 45 calendar days of the sale closing. “Identify” means a written list of potential properties sent to the Qualified Intermediary (QI) or the seller of the replacement property. The 45-day clock starts on the day of closing of the relinquished property sale — not the day of receiving proceeds, not the day of signing the exchange agreement. The deadline is absolute: there are no extensions except for presidentially-declared natural disaster areas. The identification must specify the property clearly enough to be distinguished from other properties — typically by address or legal description.
What are the 1031 exchange identification rules?
Three identification rules govern how many replacement properties can be identified: (1) Three Property Rule — any three properties regardless of fair market value. Most straightforward and most commonly used. (2) 200% Rule — any number of properties as long as their combined fair market value does not exceed 200% of the relinquished property’s sale price. (3) 95% Rule — any number of properties regardless of value, as long as 95% of the total identified value is actually acquired. The 95% rule is rarely used because it requires acquiring nearly all identified properties. Most investors use the Three Property Rule and identify exactly three properties to preserve flexibility while maintaining compliance.
What happens if you miss the 45-day 1031 exchange deadline?
Missing the 45-day identification deadline disqualifies the entire 1031 exchange. All deferred capital gains become immediately taxable in the year of the relinquished sale. There are no extensions, no grace periods, and no court-approved exceptions except for presidentially-declared major disaster areas. A missed 45-day deadline on a $500,000 gain produces an immediate federal and state tax bill of $100,000–$185,000 depending on the investor’s state and income. The stakes are high enough that most experienced investors use a countdown calendar or exchange coordination service to track the deadline and begin identifying replacement properties within the first week after closing — not waiting until day 40.
What is a reverse 1031 exchange?
A reverse 1031 exchange allows an investor to acquire the replacement property before selling the relinquished property — the opposite of a standard exchange. This is useful when the replacement property is available now but the relinquished property has not yet sold. Mechanics: an Exchange Accommodation Titleholder (EAT, a special purpose entity) holds title to the new property until the old property sells and the exchange is completed. The 180-day clock for completing the exchange runs from when the EAT acquires the replacement property. Reverse exchanges are significantly more complex and expensive than standard forward exchanges — EAT fees, additional legal and accounting costs, and financing complications (most lenders will not lend to an EAT). They are appropriate when a specific replacement property opportunity cannot be delayed and the relinquished property will clearly sell within 180 days.
