Updated September 30, 2026: The NFIP deadline moved from Sept. 30 to Dec. 11, 2026. Congress has not yet acted on anything beyond that date.

Your existing NFIP flood policy won’t disappear if the program lapses on December 11 — it stays in force until its expiration date. The real risks are renewals and new policies: during a lapse, the National Flood Insurance Program (NFIP) can’t write or renew coverage, which can complicate home closings. A seller’s policy may be transferable, and private flood insurance isn’t affected by an NFIP lapse.

The Deadline Moved: Sept. 30 → Dec. 11, 2026

Until early September, the NFIP was authorized through September 30, 2026. Section 139 of the Continuing Appropriations and Extensions Act, 2027 (H.R. 6500, Public Law 119-103) pushed that date to December 11, 2026. The measure was signed in early September 2026 and is the 36th short-term reauthorization since the end of fiscal year 2017, according to the Congressional Research Service (CRS).

Some pages still say September 30. Those are out of date. This page states the current deadline and will be updated if Congress acts again.

If authority did lapse, CRS says two things would happen on December 11: FEMA's authority to enter into new flood insurance contracts would expire, and the program's borrowing authority would fall from $30.425 billion to $1 billion. Other parts of the program technically remain authorized.

Does a Lapse Cancel Your Existing Policy?

No. Per CRS, contracts entered into before the expiration continue until the end of their policy term, which is normally one year. FEMA also says that it and Congress have never failed to honor flood insurance contracts already in place.

One limit worth knowing: requests to increase coverage on an existing policy also can't be processed during a lapse, according to FEMA's past lapse guidance. If you're planning to raise your limits, do it before December 11.

What If Your Policy Renews During a Lapse?

This is where most homeowners feel the deadline. NFIP policies don't renew by themselves: the insurer sends a renewal offer, and your premium payment renews the policy. During a lapse, FEMA's guidance to insurers says they can't issue new renewal notices. The most recent version CRS points to is a December 2024 bulletin (W-24020), which repeats the rules in FEMA's 2023 bulletin (W-23012).

Scenario: "My policy renews December 15"

Under that guidance, the outcome turns on timing:

1. If your renewal offer went out before the lapse and your insurer receives the premium before the expiration date or within the standard 30-day grace period after it (to about January 14 in this example), the insurer may renew your policy.
2. If your renewal offer had not gone out before the lapse, the insurer can't issue one during it.
3. If the premium arrives after the 30-day grace period, the insurer can't renew the policy during the lapse.

A missed renewal can mean a gap in coverage, and a new policy after a gap can carry a new 30-day waiting period. FEMA has warned that gaps can lead to denied claims.

Don't count on a repeat of 2025. During the October–November 2025 lapse, FEMA extended the renewal grace period for that lapse (Bulletin W-25005), moving the deadline for many renewals to January 15, 2026. CRS notes FEMA did not issue its usual lapse guidance that year. That extension was specific to that situation and shouldn't be assumed for December 2026. FEMA may also revise any guidance if a lapse happens, so confirm current rules with your agent or insurer.

Can You Close on a House During an NFIP Lapse?

Sometimes, but it depends. Federal law requires flood insurance on many mortgages for homes in Special Flood Hazard Areas (SFHAs), which FEMA maps as having a 1% or greater annual chance of flooding, when the community participates in the NFIP. Lenders, not FEMA, enforce that requirement. If the NFIP can't issue a policy on your closing date, what happens next may depend on your lender, your loan type, and what coverage is available.

Scenario: "I close December 18"

Here is how the pieces fit together:

• Conventional loans from federally regulated banks and credit unions. In an October 1, 2025 joint statement, the federal banking regulators reminded lenders that they may continue to make these loans when the NFIP is unavailable, without requiring NFIP coverage. Lenders must still make flood determinations and give borrowers required notices, and they're told to manage the risk. In other words, it's the lender's call, and some lenders may still want coverage in place. Government-sponsored enterprise (Fannie Mae, Freddie Mac) guides also address lapses; details vary.
• Government-backed loans (FHA, VA, USDA). These follow their own agency rules. During the 2025 lapse, at least one large FHA/VA/USDA lender's guidance to its partners still required an active flood policy for flood-zone properties and encouraged private flood coverage. Rules can change, so treat this as an example rather than a rule and ask your lender directly.
• Your own lender's overlay. Lenders can be stricter than the minimum. Ask what yours will accept.

For scale, the National Association of Realtors (NAR) estimates, as cited by FEMA, that a lapse could affect about 1,300 sales a day, roughly 40,000 a month. CRS cites estimates that during the June 2010 lapse, more than 1,400 home closings a day were canceled or delayed. Both figures are estimates or history. Neither is a forecast for December.

One timing point from FEMA's December 2024 guidance: the bulletin treated applications made before a lapse differently from those made during it. For a loan closing after a lapse began, a policy could still be issued effective on the closing date if the application and full payment were presented before the lapse and the insurer received them within 10 days of closing (30 days if paid through escrow, a title company, or a settlement attorney). Applications dated during a lapse couldn't be issued. FEMA can change this, so ask your agent whether applying and paying before December 11 makes sense for your closing.

Taking Over the Seller's NFIP Policy

If the seller has an NFIP building policy, you may be able to take it over instead of buying a new one. FEMA's flood insurance manual allows an NFIP building policy to be assigned to the buyer with the seller's written consent. NAR notes assignment keeps coverage on the property without issuing a new policy. FEMA's December 2024 lapse bulletin says that, where assignments are permitted, existing policies may be assigned during a lapse. Confirm that still holds under any newer FEMA guidance.

How it works, step by step:

1. Ask whether the property has an NFIP building policy. Your agent, the seller's agent, or the title company can ask the seller for the insurer, policy number, expiration date, and coverage amounts.
2. Get the seller's written consent. The seller signs the assignment at or before closing.
3. Submit the assignment. The buyer may submit it within 30 days after closing.
4. Coverage carries over. The assignment is effective at the transfer of ownership.

Limits to know:

• It doesn't apply to contents-only policies or to buildings under construction.
• You inherit the seller's existing coverage amounts and expiration date. Check that they meet your lender's requirements, including how long the policy runs past closing.
• It only works if the seller actually has an NFIP building policy in force.

The 30-Day Waiting Period — and Its Exceptions

New NFIP coverage normally takes effect 30 days after you apply and pay. FEMA recognizes exceptions, but they apply only when the NFIP can actually issue a policy, so they don't help if authority has lapsed and you haven't already applied.

Private Flood Insurance as a Backup

Private flood insurance isn't part of the NFIP, so an NFIP lapse doesn't shut it down. For a mortgage in a flood zone, the question is whether your lender will accept it. Under an interagency rule effective July 1, 2019, regulated lenders must accept private flood policies that meet the statutory definition, and they have discretion to accept others. Availability, price, waiting periods, and lender acceptance still vary by property and insurer.

FHA, VA, and USDA loans, and loans sold to Fannie Mae or Freddie Mac, have their own private-flood rules. Confirm the current ones with your lender before relying on a private policy. This page doesn't recommend any private insurer. For more on how the NFIP's insurer network works, see our Wright Flood Insurance review.

What Happens to Flood Claims

FEMA says that if authorization lapsed, it would still have authority to ensure valid claims are paid with available funds. FEMA's past lapse guidance says claims on policies in force are processed and paid as usual, including for losses during a lapse.

If you have a loss, report it to your insurer or agent right away, document the damage, and keep your policy and payment records.

What Past Lapses Tell Us

The NFIP has been extended 36 times on a short-term basis since the end of fiscal year 2017, and it has lapsed several times. CRS notes that in most cases Congress reauthorized the program retroactively. A retroactive fix helps policyholders and buyers, but it isn't guaranteed and doesn't tell us what will happen in December.

Source: CRS Insight IN10835, updated September 11, 2026. A separate lapse of about 13 hours occurred on March 23, 2024.

In the 2025 lapse, CRS reports that some lenders suspended the requirement for buyers to purchase flood insurance, and that early reports suggested housing markets in some states, such as Florida, were affected.

Doesn't Homeowners Insurance Cover This?

Generally, no. FEMA notes that standard homeowners insurance doesn't cover flood damage, so a flood policy is separate. See Homeowners Insurance: Hidden Coverages You're Probably Missing for what a standard policy does and doesn't include. In coastal areas, the split between wind and water damage matters even more; our Hurricane Insurance in Florida guide explains storm surge versus windstorm coverage.

What to Do Before Dec. 11

The steps below cost little and don't depend on what Congress does.

If your closing lands in a lapse:

1. Ask about a seller policy. Find out whether the seller has an NFIP building policy that can be assigned to you.
2. Request the assignment. Get the seller's written consent and confirm the paperwork timeline with the title company.
3. Line up a private option. Get a private flood quote as a backup and confirm your lender will accept it.
4. Get lender confirmation. Ask what the lender will accept on your closing date, in writing.

Flood insurance sits alongside your homeowners policy, and lenders look at both. If your homeowners insurer is dropping or not renewing you, see Home Insurance Non-Renewal and Insurance Companies Leaving States.

FAQ

When does the NFIP authorization expire?

December 11, 2026, under Sec. 139 of H.R. 6500 (Public Law 119-103).

Was the deadline moved?

Yes. It was September 30, 2026 and was extended to December 11, 2026. Older pages that say September 30 are out of date.

Does an NFIP lapse cancel my flood insurance?

No. Existing policies stay in force until their expiration dates.

Is my existing policy active during a lapse?

Yes, until its expiration date. The lapse blocks new policies and renewals, not policies already in force.

Can I renew my flood insurance during a lapse?

Insurers can't issue new renewal notices during a lapse. Under FEMA's lapse guidance, a policy can still be renewed if the renewal offer went out before the lapse and the premium arrives within the 30-day grace period. Confirm with your insurer.

What if my flood policy expires during a lapse?

Renewal timing matters. Pay any renewal bill you've received early, contact your agent if you haven't received one, and keep proof of payment. A gap can lead to a new 30-day waiting period.

Is there an NFIP renewal grace period?

Yes, normally 30 days after the expiration date. FEMA extended it for renewals during the 2025 lapse, but don't assume that will repeat.

Are flood claims paid during a lapse?

Claims on policies in force continue to be handled, but payments depend on available funds and could be delayed if funds run short.

Can I file a flood claim during a lapse?

Yes, if you have a policy in force. Report the loss to your insurer promptly.

Can I buy a house in a flood zone during a lapse?

Possibly. It may depend on your lender, loan type, and available coverage. Talk to your lender before assuming either way.

Does an NFIP lapse delay closing?

It can. NAR estimates about 1,300 sales a day could be affected, and CRS reports more than 1,400 closings a day were canceled or delayed in the 2010 lapse. Those are estimates and history, not a forecast.

Will my lender still require flood insurance?

Lenders enforce the requirement. Federal banking regulators have reminded lenders they may proceed without NFIP coverage during a lapse, but each lender decides what it will do, and some loan types have their own rules.

Can a buyer take over the seller's NFIP policy?

Often yes, for a building policy, with the seller's written consent. It isn't available for contents-only policies or buildings under construction.

How do I transfer an NFIP policy to the buyer?

The seller signs the assignment at or before closing, the buyer submits it within 30 days after closing, and it takes effect at the transfer of ownership.

What is the NFIP loan exception waiting period?

When the initial purchase is tied to making, increasing, extending, or renewing a loan, coverage can take effect at closing rather than after 30 days, if the application and payment are handled on time.

What is the map-revision waiting period?

One day, for an initial purchase within 13 months after a flood map revision.

Will my lender accept private flood insurance?

Regulated lenders must accept policies that meet the statutory definition under the rule effective July 1, 2019, and may accept others at their discretion. Government-backed loan rules differ, so ask your lender.

Does private flood insurance work during an NFIP lapse?

The NFIP lapse doesn't affect it, but availability, price, and waiting periods vary.

Does homeowners insurance cover flooding?

Generally not. Flood is usually a separate policy.

How many times has the NFIP lapsed?

Several times, including October 1 to November 12, 2025 and February 1 to 3, 2026. CRS lists earlier lapses in its Insight IN10835.
