Severe storms, flooding, hurricanes, tornadoes, wildfires, and straight-line winds can devastate communities overnight. When a federally declared disaster strikes, the IRS announces tax relief that gives impacted taxpayers and businesses extra time to file returns, make payments, and recover financially. Understanding how tax disaster declarations work before a storm or hurricane hits can save you money and prevent costly filing mistakes.

This guide explains who qualifies for IRS disaster relief, what deadlines get postponed, how to claim casualty loss deductions, and how Arizona taxpayers can take advantage of both federal and state disaster relief programs. Whether you were impacted by severe winter storms, straight-line winds, or flooding, this expert overview covers the rules you need to know.

What Is a Federally Declared Disaster for Tax Purposes?

A federally declared disaster, for tax purposes, is any disaster that receives a declaration from the Federal Emergency Management Agency (FEMA). Under IRC Section 7508A, the Internal Revenue Service may postpone filing deadlines, payment dates, and other time-sensitive acts for taxpayers impacted by such disasters.

Not every natural disaster automatically triggers IRS relief. The storm, hurricane, flood, or wildfire must receive an official FEMA disaster declaration, and the IRS then announces specific postponed dates for affected areas. These announcements specify which counties and tribal nations are eligible, the original dates that are extended, and the new deadline that applies.

For example, in June 2026 the IRS announced tax relief for the San Carlos Apache Tribe in Arizona after severe storms and flooding, giving impacted taxpayers until September 28, 2026 to file returns and pay taxes owed. In early 2025, California wildfire victims and Texas storm victims also received extended deadlines with dates postponed through the fall.

Who Is Eligible for IRS Disaster Tax Relief?

Three categories of taxpayers qualify for disaster tax relief:

  • Residents and businesses in the disaster area. Taxpayers whose principal residence or principal place of business is in a county, city, or tribal nation included in the FEMA disaster declaration receive automatic relief. The Internal Revenue Service identifies these taxpayers based on their address of record and applies the filing extension without any action required.
  • Taxpayers whose records are in the disaster area. If your tax preparer, accountant, or records storage facility is located in a designated disaster area and you cannot access your records, you are eligible for relief. This also applies to shareholders of S corporations or partners in partnerships whose entity records are in the affected area.
  • Relief workers and others affected. Individuals assisting in recognized government or philanthropic disaster relief activities in the area may also qualify.

Taxpayers in the first category receive automatic extensions. Those in the second or third category must request disaster relief by calling the IRS Special Services line at (866) 562-5227.

What Deadlines Are Postponed?

When the IRS announces disaster tax relief for a storm, hurricane, or other emergency, the postponement typically covers:

  • Income tax returns and payments. Individual (Form 1040), corporate, estate, trust, partnership, and S corporation returns with original or extended due dates falling within the disaster relief period. This includes the April 15 filing deadline and, in many cases, estimated payments due in January, April, June, and September.
  • Estimated tax payments. Quarterly estimated income tax payments that fall within the disaster relief window, including those sometimes postponed to February or later, are pushed to the new date.
  • Payroll and excise tax deposits. Penalties on deposits due within a short window after the storm or disaster date are typically abated if the deposits are made promptly.
  • IRA and HSA contributions. The deadline for making contributions for the prior tax year is extended to the new postponed date.
  • Other time-sensitive acts. Filing claims for refund, 1031 exchange identifications, and other actions listed under IRC Section 7508(a) may also be postponed.

The IRS maintains a current list of all active disaster relief announcements on its Tax Relief in Disaster Situations page. Check this page to confirm whether your area qualifies and which specific dates apply.

Claiming Casualty Loss Deductions After a Disaster

Taxpayers who suffer property losses from a federally declared disaster may be eligible to deduct those losses on their federal income tax return. The rules differ depending on whether the property is personal-use or business property.

Personal-Use Property Losses

Under current tax law (made permanent by the TCJA and confirmed by the One Big Beautiful Bill Act), individuals can only deduct casualty losses on personal-use property (homes, vehicles, household items) if the loss is attributable to a federally declared disaster. Losses from storms or hurricanes that do not receive a federal disaster declaration are generally not deductible.

The deduction is calculated as follows:

  1. Determine the smaller of: the decrease in fair market value, or the adjusted basis of the property.
  2. Subtract any insurance reimbursement or other recovery.
  3. Subtract $100 per casualty event (or $500 per casualty for qualified disaster losses).
  4. Subtract 10% of your adjusted gross income from the total net losses. However, qualified disaster losses are exempt from this 10% AGI floor.

A "qualified disaster loss" occurs in an area eligible for individual or public assistance under a Presidential major disaster declaration. For these losses, taxpayers can claim the deduction without itemizing on Schedule A (using the increased standard deduction on Form 1040). This is an important distinction, because not every FEMA disaster declaration triggers this favorable treatment.

Losses must be reported on Form 4684 (Casualties and Thefts).

Business and Income-Producing Property Losses

Business property losses from any casualty remain deductible regardless of whether a federal disaster declaration was issued. The $100/$500 per-casualty floor and the 10% AGI threshold do not apply to business or income-producing property. If a business loses equipment, inventory, or a commercial building in a winter storm or hurricane, the deductible loss equals the adjusted basis minus any insurance recovery, without additional floors.

Prior-Year Election: Getting Your Money Back Faster

One of the most valuable provisions for disaster victims is the ability to elect to claim the loss on the prior tax year return. For example, a loss from a 2025 winter storm or hurricane can be deducted on your 2024 return by filing an amended return (Form 1040-X) with Form 4684 Section D attached. The deadline to make this election is October 15 of the year following the disaster year (six months after the regular April 15 filing due date). Reporting the disaster loss on the prior year return often means a faster refund, putting money back in your hands when you need it most.

SBA Disaster Loans and Financial Assistance

The Small Business Administration (SBA) provides low-interest disaster loans to help businesses, homeowners, renters, and private nonprofit organizations recover from declared disasters. Note that the SBA offers loans, not grants; FEMA provides grants through its Individual Assistance program.

SBA disaster loan highlights:

  • Physical disaster loans: Available to businesses of all sizes, homeowners, and renters to repair or replace property damaged by a storm, hurricane, or other severe weather event.
  • Economic Injury Disaster Loans (EIDL): Working capital for small businesses that suffer substantial economic injury, even if the business was not physically damaged.
  • Interest rates: Not exceeding 4% for businesses that cannot obtain credit elsewhere, with up to 30-year terms and 12-month payment deferral. No prepayment penalty.
  • Collateral: Required for loans over $50,000.

To apply, visit SBA.gov or call (800) 659-2955. Applications can also be submitted at FEMA Disaster Recovery Centers. Check currently eligible disaster areas and dates on the SBA website before applying.

Arizona Disaster Tax Relief

Arizona faces severe weather events including monsoon flooding, wildfires, and winter storms that can trigger federal disaster declarations. Most recently, the San Carlos Apache Tribe received an IRS disaster relief announcement (AZ-2026-01) in June 2026 after severe storms and flooding, with deadlines postponed to September 28, 2026. Texas, California, and other states have also received multiple disaster announcements in recent years.

Key Arizona considerations for impacted taxpayers:

  • State filing extension: The Arizona Department of Revenue (ADOR) generally follows federal disaster extensions, granting parallel relief for Arizona income tax returns.
  • Federal changes flow through: If a casualty loss deduction changes your federal adjusted gross income, your Arizona state income tax liability will also change since Arizona uses federal AGI as the starting point for its 2.5% flat income tax.
  • Business considerations: Arizona's Transaction Privilege Tax (TPT) obligations may also be affected if a severe storm disrupts operations. Contact ADOR directly for TPT filing relief in declared disaster areas.

How to Prepare Before a Storm or Hurricane Strikes

The best time to understand disaster tax relief is before you need it. An expert tax advisor can help you build a plan, but you can start with these steps:

  • Document your property. Maintain photos, receipts, and appraisals of major assets. The IRS recommends using its disaster preparedness resources to create a home inventory.
  • Store records safely. Keep copies of tax returns, insurance policies, and financial records in a fireproof safe or cloud storage. This protects you whether a storm, winter freeze, or wildfire strikes.
  • Review insurance coverage. Since the casualty loss deduction only applies to uninsured losses, adequate insurance coverage is the first line of defense and saves you money in the long run.
  • Know your filing status. After a severe event, you may be eligible for a change in filing status (for example, if a spouse passes away during a disaster, qualifying surviving spouse treatment may apply).

Frequently Asked Questions

Do I have to live in the disaster area to get IRS relief?

No. If your tax records, preparer, or business records are located in a designated disaster area and you cannot access them, you can request disaster relief by calling the IRS at (866) 562-5227. Relief workers assisting victims in the disaster area also qualify.

Can I deduct disaster losses without itemizing?

Only if your loss qualifies as a "qualified disaster loss" (occurring in an area designated for individual or public assistance under a Presidential major disaster declaration). In that case, you can take an increased standard deduction and claim the loss on Form 4684 without filing Schedule A. Other federally declared disaster losses still require itemizing.

How quickly can I get a refund by electing the prior-year deduction?

The prior-year election typically results in a refund within weeks of filing the amended return, compared to waiting until the following tax season. For a 2025 disaster, you have until October 15, 2026 to file an amended 2024 return claiming the loss.

Does the IRS automatically know I am in a disaster area?

Yes, for taxpayers whose address of record is in a FEMA-designated disaster area. The Internal Revenue Service automatically identifies affected taxpayers and applies the filing extension. You do not need to call or write. However, if you recently moved or your address is not updated, call the disaster hotline.

What if my insurance claim is still pending?

You should claim the disaster loss based on a reasonable expectation of what insurance will pay. If the actual reimbursement differs, you may need to file an amended return or report the difference as income in the year you receive the payment.
