1031 exchange disaster extension 2026: who qualifies and how the 45/180-day clock moves
What is a 1031 exchange disaster extension? When the IRS publishes a disaster relief notice for a federally declared disaster, certain 1031 exchangers can postpone the 45-day identification deadline, the 180-day exchange deadline, or both. The new date comes from that notice and from Rev. Proc. 2018-58, not from a FEMA posting alone. Confirm your county and original due date against the IRS notice before you treat any date as moved.
Who qualifies for a 1031 deadline postponement after a disaster? You may qualify if you meet the "affected taxpayer" definition in the IRS disaster notice for that event, or under Rev. Proc. 2018-58 §17 if your exchange started on or before the disaster date and the disaster makes identification or closing difficult (property, parties, documents, lender, or title in the covered area). Eligibility is notice-specific. Match your facts to the published notice.
How does Rev. Proc. 2018-58 move the 45-day and 180-day clocks? Under §17, qualifying deadlines that fall on or after the disaster date can be postponed by 120 days or to the last day of the notice's postponement period, whichever is later, capped by your tax-return due date (including extensions) or one year. §6 can move deadlines that fall inside the postponement window to the window's last day. Your QI needs the new dates in writing.
If a disaster hit your close, lender, title shop, or county, identify a DST interest as backup replacement while you sort the new dates. When you're ready, view listings.
What a 1031 exchange disaster extension is
A 1031 exchange disaster extension is IRS relief that can move your Day 45 identification deadline, your Day 180 exchange deadline, or both, when a federally declared disaster disrupts the exchange. Relief comes from an IRS disaster relief notice plus Rev. Proc. 2018-58, not from a FEMA post or presidential declaration alone. Postponements apply only when the IRS publishes a notice for that disaster and locality; confirm your county and original due date against that notice. For Day 45 rules once dates are set, see the 45-day identification guide.
Who qualifies
Eligibility is notice-specific. Read the IRS notice for your disaster, then match your facts to it.
Affected taxpayers under the IRS notice
You may qualify as an "affected taxpayer" if you live or work in the covered disaster area, or if your principal place of business sits there, as the notice defines it. Start with the IRS list: Tax relief in disaster situations.
Section 17 path (including some non-affected taxpayers)
Under Rev. Proc. 2018-58 §17, some exchangers who are not "affected taxpayers" can still qualify if (1) relinquished property transferred (or parked property parked) on or before the disaster date, and (2) the disaster makes identification or closing difficult for a listed reason (property or a party's business in the covered area; a party killed, injured, or missing; documents lost; lender will not fund; or title insurance unavailable). If the exchange started after the disaster date, §17's 120-day add generally is not available.
An IRS disaster notice is required
A FEMA or presidential declaration does not postpone 1031 deadlines by itself. An IRS Disaster Relief Notice is required (Rev. Proc. 2018-58 §17.01). Until that notice posts, Day 45 and Day 180 stay put.
How the 45-day and 180-day clock moves (Rev. Proc. 2018-58)
Section 17 postponement math
Under §17, qualifying deadlines on or after the disaster date can be postponed by 120 days, or to the last day of the notice's postponement period, whichever is later. Caps: your tax-return due date for the year of the transfer (including extensions), or one year.
Section 6 vs Section 17
Section 6 applies only to affected taxpayers as the notice defines them; deadlines inside the postponement window move to the window's last day. Section 17 can reach farther (later of 120 days or the notice end) and can cover some non-affected taxpayers who meet the difficulty tests, but the exchange generally must have started on or before the disaster date.
If Day 45 already passed
If the identification period had already expired by the disaster date, only the exchange period typically moves under §17, unless identified replacement property was substantially damaged, in which case identification can also be postponed (§17.03).

What to do next
Confirm the notice
Open the IRS tax relief in disaster situations list. Find your notice code, covered localities, disaster date, and postponement date. Re-check before you lock dates into your exchange file.
Tell your QI in writing
Tell your qualified intermediary, in writing, that you are eligible, that you are taking the relief, and what your new deadline dates are. If you do not, the original Day 45 and Day 180 control.
Note on exchange funds
Accepting a postponement can delay return of unspent exchange funds until after the new deadlines, unless the exchange ends earlier under your exchange agreement and Treasury Reg. §1.1031(k)-1(g)(6).
Use a DST as backup identification when the clock moves
When timelines are compressed or extended, a Delaware Statutory Trust interest can be identified as replacement property, or as a backup under the 3-property / 200% rules on the Day 45 page.
A DST holds title to investment real estate; investors own an interest in the trust rather than running the building (what a DST is). DST interests are generally sold through private placements. 1031 Specialist works with investors who have at least $100,000 to place.

Who qualifies for a 1031 deadline postponement after a disaster?
You may qualify if you meet the "affected taxpayer" definition in the IRS disaster notice for that event, or under Rev. Proc. 2018-58 §17 if your exchange started on or before the disaster date and the disaster makes identification or closing difficult (property, parties, documents, lender, or title in the covered area). Eligibility is notice-specific. Match your facts to the published notice.
How does Rev. Proc. 2018-58 move the 45-day and 180-day clocks?
Under §17, qualifying deadlines that fall on or after the disaster date can be postponed by 120 days or to the last day of the notice's postponement period, whichever is later, capped by your tax-return due date (including extensions) or one year. §6 can move deadlines that fall inside the postponement window to the window's last day. Your QI needs the new dates in writing.
Do FEMA or presidential declarations alone postpone 1031 deadlines?
No. FEMA notices and presidential declarations do not postpone 1031 deadlines by themselves. An IRS Disaster Relief Notice is required under Rev. Proc. 2018-58 §17.01. Until the IRS publishes that notice for your disaster and locality, Day 45 and Day 180 stay on the original calendar.
What should I tell my qualified intermediary if I'm taking disaster relief?
Tell your QI in writing that you are eligible, that you are taking the relief, and what your new identification and exchange deadline dates are. If you do not, the original Day 45 and Day 180 control. Accepting the postponement can also delay return of unspent exchange funds until after the new dates.
Can a DST serve as backup identification when disaster relief compresses or extends my timeline?
Yes. A DST interest can be identified as replacement property, or as a backup under the 3-property / 200% identification rules, while you sort new dates or wait on a delayed close. The same clocks still apply once your dates are set.
