If your business sits in Avoyelles, St. Landry, St. Tammany, or Terrebonne Parish, you just picked up an extra four months to deal with the IRS. Following Tropical Storm Arthur, which struck south and central Louisiana starting June 17, 2026, the IRS pushed nearly every federal tax deadline for affected taxpayers to November 2, 2026 — no application required.
That's not a small grace period. It covers a full quarterly payroll filing, a round of estimated tax payments, and for many small businesses, the extension on last year's return. But "automatic" doesn't mean "automatic if you do nothing right." A surprising number of business owners in federally declared disaster areas either miss the relief because they don't realize they qualify, or misuse it because they assume it covers more than it does. Here's what actually changed, who it applies to, and how to use the extra time without creating a bigger mess in November.
What Happened and Why the IRS Is Involved
Tropical Storm Arthur brought heavy rain, flooding, and wind damage across parts of Louisiana beginning June 17, 2026. Once FEMA issued a federal disaster declaration for the affected parishes, the IRS automatically triggered its standard disaster-relief mechanism under Internal Revenue Code Section 7508A — the same authority it uses after hurricanes, wildfires, and severe winter storms nationwide.
The declaration carries FEMA disaster number 4927-DR. If you ever need to reference the relief on a return, an amended filing, or a call with the IRS, that number is your citation.
Four parishes are currently covered:
- Avoyelles Parish
- St. Landry Parish
- St. Tammany Parish
- Terrebonne Parish
If you live or run a business in one of these parishes, the relief applies to you without any paperwork. The IRS identifies eligible taxpayers using ZIP codes tied to the disaster area and flags accounts automatically. You don't file a special form to "opt in."
The New Deadline: November 2, 2026
Any tax filing or payment deadline that fell (or falls) between June 17, 2026, and November 2, 2026 is postponed to November 2, 2026. That single rule sweeps in a lot of different obligations:
Returns affected:
- Individual income tax returns (including those on extension)
- Corporate income tax returns (C corps and S corps)
- Partnership returns
- Estate and trust income tax returns
- Gift and generation-skipping transfer tax returns
- Annual information returns for tax-exempt organizations
Payments and deposits affected:
- Quarterly estimated income tax payments due on or after June 17, 2026
- Quarterly payroll and excise tax returns normally due July 31, 2026
If your business had a return on extension with an original deadline that fell inside this window — for example, a partnership or S-corp return that was due September 15 — that deadline also rolls to November 2. Same logic for an individual return that was extended to October 15: if the extended due date falls inside the postponement window, it moves too.
What's Not Covered
The relief has real edges, and this is where business owners most often trip up:
- Payroll and excise tax deposits are not postponed, only the returns are. If you have employees, you're still expected to make timely federal tax deposits. The one carve-out: penalties on deposits due between June 17 and July 2, 2026 are waived automatically, as long as the deposits were made by July 2, 2026. That's a narrow, already-closed window — worth checking if you fell behind in those first two weeks.
- Information returns are excluded. W-2s, the 1099 series, Forms 1042-S, 3921, 3922, and 8027 all keep their normal due dates. If you're a business that issues 1099s to contractors, that deadline did not move.
- The postponement doesn't erase tax owed — it only delays the paperwork and payment deadline. Interest generally doesn't accrue during a properly claimed postponement period on the amounts covered, but this is a deadline extension, not a forgiveness program.
Who Qualifies Beyond the Four Parishes
The disaster-area boundary doesn't fully define who gets relief. The IRS extends the postponement to:
- Any taxpayer whose records necessary to meet a filing deadline are located in the covered disaster area, even if the taxpayer themselves is elsewhere. If your bookkeeper, payroll processor, or accountant is based in one of the four parishes and your records are effectively stuck there, you may qualify even if your own business address is outside the disaster zone.
- Relief workers affiliated with a recognized government or philanthropic organization who are assisting with relief activities in the covered area.
- Anyone injured or killed while visiting the covered disaster area as a result of the storm (relevant to certain estate and casualty-related filings).
If you're a business owner just outside the four listed parishes but your CPA's office is inside one, don't assume you're excluded — call the IRS disaster hotline and ask them to manually code your account for relief.
Claiming the Relief: What You Actually Need to Do
For most taxpayers, this is refreshingly low-friction:
- Do nothing extra if your address is already in the disaster area. The IRS matches your account to the FEMA-declared ZIP codes and applies the postponement automatically. You don't file a form.
- If you get a late-filing or late-payment penalty notice anyway, call the number on the notice and explain that your address is in the covered area, citing FEMA declaration 4927-DR. The IRS abates the penalty once confirmed.
- If you qualify because your records are in the area but your address isn't, you likely need to call the IRS disaster line directly (866-562-5227) to have relief applied manually, since automatic matching only works off address data.
Keep a written record of that call — date, time, representative ID if given, and what was confirmed. Disaster-relief account flags occasionally don't stick on the first pass, and a note in your files makes a second call much faster.
The Casualty Loss Election: An Underused Option
If your business took physical damage — flooded inventory, damaged equipment, a wrecked storefront — you may be entitled to claim a casualty loss deduction. The relevant provision here is Section 165(i), which lets disaster victims choose which tax year to claim the loss on:
- The year the loss actually occurred, or
- The prior tax year — meaning you can amend last year's already-filed return to claim the loss now, rather than waiting to file this year's return.
The value of the prior-year election is speed: if you had a strong prior year and a rough disaster year, claiming the loss against last year's income can generate a faster refund than waiting for this year's return to process. The IRS also extends the normal election deadline — you get six additional months past the standard filing deadline to make this choice, specifically because of the disaster.
Casualty loss calculations require documenting the property's basis, the decline in fair market value from the damage, and any insurance or FEMA reimbursement you received or expect to receive (which reduces the deductible loss). This is a case where working with a tax professional pays for itself; the math is unforgiving of guesswork, and an overstated loss invites scrutiny.
Practical Steps for the Next Four Months
1. Don't let the extension become an excuse to lose track of what's actually due. November 2 will arrive fast, and it's compressing what would normally be several separate deadlines into one date. Build a simple calendar reminder now, not in October.
2. Keep making payroll tax deposits on schedule. This is the most common mistake business owners make with disaster relief — they see "IRS extended our deadlines" and stop making deposits that were never actually postponed. The return filing moved; the deposit obligation for most periods didn't.
3. Document storm damage now, while it's fresh. Photos, repair invoices, inventory loss counts, and insurance claim correspondence all matter later if you pursue a casualty loss election. Waiting until you sit down to do the amended return means reconstructing records from memory.
4. Reconcile your books before November, not during the scramble. If your records got physically damaged or you were displaced from your office, this is exactly the situation where clean, current bookkeeping either saves you or costs you. A business with an up-to-date general ledger can hand a CPA clean numbers in an afternoon; a business with a shoebox of receipts is looking at weeks of reconstruction under time pressure.
5. If you use a payroll or bookkeeping service based in the affected parishes, confirm with them directly whether your account has been flagged for relief — don't assume it carries over automatically just because they're located there.
Keep Your Records Storm-Proof Going Forward
Disaster relief windows exist because paper records, local offices, and even cloud logins tied to a single regional provider can all become unreachable overnight. Beancount.io stores your financial records in plain-text, version-controlled files — the kind of format that survives on a laptop, a phone, or a backup drive regardless of what happens to any single office or vendor. If you're rebuilding your bookkeeping workflow after this storm, get started for free and see why developers and finance-minded business owners are moving to plain-text accounting for exactly this kind of resilience.
