1031 Exchange Deadline Calculator
Important Considerations
Qualified Intermediary: You must use a QI to facilitate the exchange. Funds cannot be in your possession during the exchange period.
Like-Kind Property: Replacement property must be of "like-kind" - generally any real estate held for investment or business use in the U.S.
Equal or Greater Value: To defer all taxes, the replacement property must be of equal or greater value and all equity must be reinvested.

Master Your 1031 Exchange Deadlines
Your Complete Guide to Tax-Deferred Real Estate Exchanges with Deadline Calculator
Imagine selling an investment property and being able to defer ALL capital gains taxes - potentially saving tens or hundreds of thousands of dollars. That's exactly what a 1031 exchange offers! But there's a catch: strict deadlines that can make or break your tax savings.
This guide will walk you through everything you need to know about 1031 exchange deadlines, complete with real examples and our interactive calculator that helps you track every important date.
What is a 1031 Exchange?
A 1031 exchange (named after Section 1031 of the U.S. Internal Revenue Code) is a powerful tax strategy that allows you to:
- ✅ Sell an investment property (called the "relinquished property")
- ✅ Buy another investment property (called the "replacement property")
- ✅ DEFER ALL capital gains taxes on the sale
Simple Example:
You sell a rental property for $500,000 that you originally bought for $300,000. Normally, you'd pay capital gains tax on the $200,000 profit. With a 1031 exchange, you can defer all $200,000 in taxes by reinvesting in another property!

Never miss a deadline again! Track your 45-day identification and 180-day purchase deadlines with our easy-to-use calculator.
The Two Critical Deadlines You MUST Know
1031 exchanges have two non-negotiable deadlines. Missing either one means losing your tax deferral!
Critical Warning
These deadlines are ABSOLUTE. The IRS does NOT grant extensions for weekends, holidays, or any other reasons. If you miss these deadlines by even one day, you lose your tax deferral and must pay all capital gains taxes immediately.
How Our Calculator Works (Simple Formula)
Our calculator uses simple date calculations based on IRS rules:
Basic Formula:
Identification Deadline = Closing Date + 45 Days
Purchase Deadline = Closing Date + 180 Days
But there's an important twist: The purchase deadline CANNOT extend beyond your tax return due date (typically April 15th with extensions).
Calendar Days vs. Business Days
This is crucial to understand:
- Calendar Days: Count every single day (weekends, holidays, all days)
- Business Days: Count only Monday through Friday (exclude weekends and federal holidays)
For 1031 exchanges, the IRS uses CALENDAR DAYS for both deadlines. Our calculator lets you choose to help with planning, but legally, you must use calendar days.
Real-Life Example Walkthrough
Sarah's Investment Property Exchange
Sarah's Situation:
- Sells her rental property on March 1, 2024
- Tax return due date with extension: October 15, 2024
- Wants to defer $150,000 in capital gains taxes
Using our calculator:
- 📅 45-Day Identification Deadline: April 15, 2024
- 🏁 180-Day Purchase Deadline: August 28, 2024
But wait! Because Sarah's tax return due date (October 15) is LATER than the 180-day deadline (August 28), she uses the August 28 deadline.
Identification Rules You Need to Know
When identifying properties, you have three options:
| Rule | What It Means | Best For |
|---|---|---|
| 3-Property Rule | Identify up to 3 properties of any value | Most common choice - simple and flexible |
| 200% Rule | Identify any number of properties if total value ≤ 200% of sold property | When you want more options but have a budget limit |
| 95% Rule | Identify any number of properties if you buy 95% of identified value | Advanced strategy - rarely used |
Pro Tip: Use the 3-Property Rule
For most investors, the 3-Property Rule is the safest and simplest choice. It gives you flexibility without complex calculations. Our calculator defaults to this rule for a reason!

How to Use the Calculator (Step by Step)
Step 1: Enter Your Closing Date
Enter the exact date you closed (or will close) on selling your property. This is your Day 0.
- Get this date from your closing documents
- If planning ahead, use your expected closing date
- Be precise - even one day off can ruin your calculations!
Step 2: Choose Identification Method
Select which identification rule you'll use:
- 3-Property Rule: Choose this unless you have a specific reason not to
- 200% Rule: Only if you're identifying many properties with a total value limit
- 95% Rule: Rarely used - consult with a tax professional first
Step 3: Set Your Extension Date
Enter your tax return filing deadline with extensions:
- Typically October 15th if you file for an extension
- If you don't file for extension, use April 15th
- This is CRITICAL - it can shorten your 180-day period!
Step 4: Calculate!
Click "Calculate Deadlines" to see:
- Your exact 45-day identification deadline
- Your exact purchase deadline (180 days or tax deadline, whichever comes first)
- How many days you have remaining
- Visual timeline showing your progress

Common Pitfalls to Avoid
Deadly Mistakes That Cost Investors Thousands
1. Missing the 45-Day Deadline: Even if you have a property lined up, if you don't submit written identification by Day 45, you lose everything.
2. Counting Business Days: The IRS counts calendar days. If you plan for business days, you'll be late.
3. Forgetting the Tax Deadline: If your tax return due date (with extension) is before Day 180, that becomes your purchase deadline!
4. Not Using a Qualified Intermediary (QI): You MUST use a QI. If you touch the sale proceeds, the exchange is invalid.
