- Year of the forced sale IRC § 451(g) lets a cash-method farmer defer income from an excess livestock sale to the following year
- Up to 4 years to replace IRC § 1033(e) defers gain on draft, breeding, or dairy animals sold for weather reasons, if replaced within the window
- The year before the disaster IRC § 165(i) lets a farmer elect to move a casualty loss back one year, for a faster refund
- Set by IRS notice, up to 1 year IRC § 7508A postpones filing and payment deadlines for taxpayers in the designated area
A drought that empties a pasture can set four different provisions running, and they do not share a deadline, a mechanism or an eligibility test. Two of them defer income from a forced sale, one moves a loss into an earlier year, and one moves every filing date. Working out which apply is most of the job; they are not alternatives to one another and a farm can use several at once.
The rule
What makes a disaster federal (IRC § 165(i)(5)). Nearly every provision here turns on that determination, and a state declaration is not enough for most of them.
Deferring the income from a forced sale. The choice between them is the choice between one year and indefinite.
Replacing with something other than livestock. That provision is what makes IRC § 1033(e) usable after a severe drought, when buying replacement cattle into a distressed market would be ruinous.
A wider replacement rule for everything else. Compare that with the ordinary rule: Outside a federally declared disaster, replacement property must be similar or related in service or use, which is a narrow test. Inside one, for business property, any tangible property of a type held for productive use in a trade or business qualifies — a destroyed barn can be replaced with a combine.
And for a home.
Moving a loss backwards. The election accelerates a refund by a year, which for a farm with no cash after a flood is often the point of it.
Moving every deadline.
Payments received.

How it works in practice
Start by establishing what the President actually declared and for which counties, because the answer differs by provision. The IRC § 451(g) deferral needs the area to have been designated as eligible for federal assistance, which is a broader category than a major disaster declaration and includes the drought designations issued by the Department of Agriculture. IRC § 165(i) and IRC § 1033(h) need a federally declared disaster under the Stafford Act. IRC § 7508A needs the Secretary to have determined the taxpayer affected, which is done by news release listing counties.
Then sort the herd. Animals held for draft, breeding or dairy purposes can go down the IRC § 1033(e) route, with gain deferred into replacement stock over four years. Animals held for sale cannot, and IRC § 451(g) is their only relief — one year of deferral and no more. A rancher who sells both in the same season uses both provisions, and the two elections are made separately.
For the loss election, run the numbers both ways before choosing. IRC § 165(i) moves the loss into the preceding year, which is worth having when that year’s income was high or when the refund is needed immediately, and not worth having when the disaster year will show more income than the year before. The election is made on the prior-year return, amended if it has been filed, and it treats the casualty as having occurred in that earlier year for every purpose.
Do not assume a postponement covers everything. IRC § 7508A postpones the acts listed in IRC § 7508(a)(1) — filing returns, paying tax, filing claims for refund, bringing suit and the rest — for the period the Secretary specifies, which is usually stated in the news release rather than being the full year the statute allows. It also suspends interest and penalties for that period, but only for periods after the disaster date, so an amount already delinquent keeps accruing.
The four-year window and the market that did not recover
A cow-calf operation in a county designated for federal drought assistance sells 90 breeding cows in August 2026 for $270,000, well above its usual culling. The basis in the herd, all of it raised, is zero. By 2029 the drought has broken but replacement cows are trading at nearly twice their 2026 price, and the rancher can only afford 60 head at $210,000.
The sale is an under IRC § 1033(e)(1), and IRC § 1033(e)(2)(A) gives four years rather than two because the area is federally designated, so a 2029 purchase is inside the window that closes at the end of 2030. Gain is recognised to the extent the $270,000 amount realised exceeds the $210,000 reinvested, so $60,000 is recognised and $210,000 of gain is deferred into the basis of the replacement animals. If the drought continues past three years, IRC § 1033(e)(2)(B) lets the Secretary extend the period regionally. And if replacement cattle remain unaffordable altogether, IRC § 1033(f) allows the proceeds to go into other property used for farming purposes instead — new fencing, a water system, machinery — which counts as similar or related in service or use for this purpose.
The barn and the combine
A flood in a federally declared disaster area destroys a farm’s equipment barn. Insurance pays $340,000; the barn’s adjusted basis was $95,000. The farm does not want another barn on that site and would rather spend the money on a new combine and a grain dryer.
Outside a disaster the answer would be no. IRC § 1033(a)(2)(A) requires replacement property “similar or related in service or use,” and a combine is not similar to a barn. But IRC § 1033(h)(2) applies where trade or business property located in a disaster area is involuntarily converted as a result of a federally declared disaster, and it treats any tangible property of a type held for productive use in a trade or business as similar or related in service or use. So the combine and the dryer qualify. The $245,000 of gain is deferred to the extent the $340,000 is reinvested, and the replacement period is the ordinary one under IRC § 1033(a)(2)(B) — IRC § 1033(h)(1)(B)‘s four-year extension applies to a principal residence, not to business property.
The hail in September
Hail destroys a farm’s soybean crop in September 2026 in a federally declared disaster area. Crop insurance pays $210,000 in November 2026. The farm’s uninsured stored grain, with a basis of $60,000, is also destroyed. 2025 was a strong year with substantial taxable income; 2026 will be poor.
Three provisions, three different answers. The crop insurance proceeds are income, and because the farm is on the cash method and normally sells that crop in the following spring, it may elect under IRC § 451(f) to report the $210,000 in 2027. The stored grain is a of business property and, because the loss occurred in a disaster area and is attributable to a federally declared disaster, IRC § 165(i)(1) lets the farm elect to take it into account in 2025 — the year with income to absorb it — by amending that return. And IRC § 7508A will have postponed the 2026 filing and payment dates for taxpayers in the listed counties, which buys time to make both elections properly rather than in a rush.
IRC § 451(g) and IRC § 1033(e) cover different animals. The deferral election reaches any livestock sold in excess of usual practice. The involuntary conversion route reaches only livestock held for draft, breeding or dairy purposes, and excludes poultry. A herd sold in one drought is usually split between the two.
The four-year replacement period is not universal. IRC § 1033(e)(2)(A) gives four years for weather-related livestock in a federally designated area, and IRC § 1033(h)(1)(B) gives four years for a principal residence in a disaster area. Business property converted in a disaster area gets the wider replacement property rule of IRC § 1033(h)(2) but not a longer period.
IRC § 165(i) moves the loss, not the disaster. The election treats the casualty as having occurred in the earlier year for all purposes, so the loss is measured, limited and characterised under that year’s rules. It is not a carryback and it does not create a net operating loss on its own.
A postponement is only as long as the news release says. IRC § 7508A authorises up to one year, and the Secretary routinely specifies far less. It also reaches only periods after the disaster date, so tax that was already late continues to accrue interest and penalties.
How this has changed
The four-year replacement period for weather-related livestock sales came from the American Jobs Creation Act of 2004 for sales after 31 December 2002, and the regional extension power in IRC § 1033(e)(2)(B) with it. Before that a rancher had two years, which in a multi-year drought was often no time at all.
IRC § 139 was added by the Victims of Terrorism Tax Relief Act of 2001 and extended to disasters generally. It matters to farms mostly through subsection (b)(4) — a government payment made in connection with a qualified disaster to promote the general welfare — which is the provision under which many state and local disaster grants escape tax, provided the expense is not otherwise compensated.
IRC § 7508A gained subsection (d) through the Taxpayer Certainty and Disaster Tax Relief Act of 2019, creating a mandatory 60-day postponement period running from the earliest incident date, so that relief no longer depends entirely on the Secretary exercising discretion. The discretionary postponement under subsection (a) sits on top of it.
The casualty loss rules for individuals narrowed sharply and then partially reopened. IRC § 165(h)(5) suspended the personal casualty loss deduction except for losses attributable to a federally declared disaster, and Pub. L. 119-21 § 70435 extended that treatment to state-declared disasters for losses after 2025. Business casualty losses on a farm were never subject to that suspension.
Exam focus
Know the four reliefs and what triggers each: IRC § 451(g) for a one-year deferral of forced-sale income, IRC § 1033(e) for involuntary conversion treatment of draft, breeding and dairy animals, IRC § 165(i) for the prior-year loss election, and IRC § 7508A for deadlines.
Know the replacement periods and which is which — four years for weather-related livestock in a designated area, four years for a principal residence in a disaster area, two years otherwise.
Know that IRC § 1033(h)(2) widens what counts as replacement property for business property in a disaster area, and that IRC § 1033(f) lets livestock proceeds go into other farm property where replacing the animals is not feasible.
Check yourself
1. A farmer sells 200 head of feeder cattle in a drought, 120 more than usual, in a county designated for federal assistance. May she use IRC § 1033(e)?
Answer: No. IRC § 1033(e)(1) reaches livestock held for draft, breeding or dairy purposes. Feeder cattle are held for sale, so the involuntary conversion route is closed. Her relief is the IRC § 451(g) election, which defers the excess-sale income to the following year — provided farming is her principal trade or business and the area is designated as eligible for federal assistance.
2. A federally declared flood destroys a farm’s irrigation system in 2026. The farm elects under IRC § 165(i) to claim the loss in 2025. Its 2025 return has already been filed. What happens?
Answer: The farm amends the 2025 return to claim the loss, and IRC § 165(i)(2) treats the casualty as having occurred in 2025 for all purposes of the Code. The amount claimed cannot exceed the uncompensated amount determined on the facts existing when the loss is claimed, so any insurance recovery reasonably expected at that point reduces it.
3. A drought makes replacement breeding cattle unavailable at any sensible price. The rancher uses the IRC § 1033(e) proceeds to build a new water system and buy hay equipment. Does the deferral survive?
Answer: Yes. IRC § 1033(f) provides that where weather-related conditions make it infeasible to reinvest the proceeds of involuntarily converted livestock in similar property, other property used for farming purposes is treated as similar or related in service or use. The water system and equipment qualify. Real property qualifies only in the soil or environmental contamination cases.
4. The Service issues a news release postponing filing and payment deadlines to 15 October for taxpayers in listed counties. A farm in one of those counties already owed unpaid 2024 tax when the disaster struck. Does interest stop?
Answer: No, not on the pre-existing liability. IRC § 7508A(a)(2) disregards the specified period in determining interest, penalties and additions to tax “for periods after such date” — the date of the disaster — as respects the acts postponed. An amount already delinquent before the disaster continues to accrue interest on its own account.
5. A state pays a farm $15,000 under a disaster grant programme to cover fence rebuilding after a wildfire in a federally declared disaster area. Insurance has already paid $9,000 toward the same fence. Is the grant excludable?
Answer: Partly at most, and probably not at all here. IRC § 139(b) reaches payments to or for the benefit of an individual, and the qualified disaster relief payment categories are directed at personal, family, living and funeral expenses and at a personal residence. A business fence is outside them. Even where a category applied, the closing words of IRC § 139(b) exclude any expense compensated by insurance or otherwise, so the $9,000 already recovered could not be covered twice.
Change log
- Initial draft. Separates the four distinct reliefs a weather event can trigger — the IRC § 451(g) one-year deferral, IRC § 1033(e) involuntary conversion treatment with its four-year replacement period, the IRC § 165(i) election to claim a disaster loss in the preceding year, and the IRC § 7508A postponement of deadlines — and adds the IRC § 1033(f) rule allowing other farm property as replacement where reinvestment in livestock is not feasible, the IRC § 1033(h)(2) wide replacement rule for business property in a disaster area, and the IRC § 139 exclusion.
- Added a plain-language summary, a timeline diagram of the four reliefs, typed the three scenarios, and marked two glossary terms.
