# [Important Steps to Take When Starting a 1031 Exchange Late in the Year (2026 Update)](https://blog.fgg1031.com/blog/1031-exchange-late-in-year-2026)

Most real estate investors know the two deadlines in a 1031 exchange. You have 45 days after closing on the sale of your relinquished property to identify replacement properties. You have up to 180 days after that same closing to complete the purchase.

The part people miss is “up to.” If you start an exchange between October 18, 2026, and December 31, 2026, your exchange period may end before day 180. Under Section 1031, you must acquire your identified replacement properties by one of two dates, whichever comes first. The first is 180 days after closing on the sale. The second is the due date of your tax return for the year of the sale.¹ For most individual taxpayers, the 2026 return is due April 15, 2027.

Here’s how that plays out. Say you sell a rental property on November 20, 2026. Day 180 would fall on May 19, 2027. But your 2026 return is due April 15, 2027. Without an extension, you’d have only 146 days to close on your replacement properties.

**If there**’**s a chance you**’**ll need the full 180 days, plan on filing a tax extension.**

#### **Filing an Extension to Restore the Full 180-Day Exchange Period**

To get the full 180 days back, file IRS Form 4868 before April 15, 2027. This gives you an automatic six-month extension and moves your filing deadline to October 15, 2027. It doesn’t give you any extra time to complete the exchange, though. You still have to close on all replacement properties within 180 days of selling your relinquished property.

Going back to the example, if you closed on November 20, 2026, and filed an extension, your deadline to acquire replacement properties would be May 19, 2027.

An extension can’t be filed after April 15. For that reason, many investors file well ahead of time rather than waiting until the week of Tax Day.

#### **When It May Make Sense to Let the Exchange Period End Early**

An extension isn’t always the right move. Some investors expect to have money left in their exchange account after buying their replacement properties. That can happen if they buy only some of the properties they identified. It can also happen if they’ve decided to take part of their exchange proceeds as cash.

Qualified intermediaries are generally required to hold exchange funds until one of two things happens: all identified replacement properties have been purchased, or the exchange period ends. If you file an extension, the exchange period runs the full 180 days, and any leftover funds stay with your intermediary until then. If you don’t file an extension, your exchange period ends April 15, 2027, and unused funds can typically be released shortly after.

Keep in mind that cash you receive back from the exchange is generally taxable as boot. That trade-off is worth talking through with your tax advisor before you decide.

#### **Reporting Exchange Funds Received the Following Year**

Suppose your exchange began in 2026 and you receive leftover exchange funds in 2027. In that case, you may be able to report the gain on your 2027 return instead of your 2026 return. This treatment generally applies only if you had a bona fide intent to complete an exchange when you started it. Your tax advisor can confirm whether it applies to your situation.

#### **Additional Considerations**

An extension gives you more time to file, not more time to pay. Any tax you owe for 2026 is still due April 15, 2027. The IRS generally won’t charge a late-payment penalty on an extended return if two conditions are met. You must have paid at least 90% of your actual 2026 tax by the original due date, and you must pay the balance when you file. Interest still accrues on any unpaid amount.

Check your state’s rules too. California, for example, grants an automatic six-month extension to file. If you owe California tax, though, you’ll still need to pay it by April 15 using Form FTB 3519.

If you or your property is located in a federally declared disaster area, the IRS sometimes postpones 1031 exchange deadlines as part of its disaster relief. Those postponements are specific to each disaster, so confirm the details with your qualified intermediary before relying on one.

As always, check with your tax advisor to make sure you’re meeting the requirements for your specific transaction.
