Five years into the Federal Emergency Management Agency's (FEMA) overhaul of the National Flood Insurance Program (NFIP), a new report finds that most of the remaining $2.6 billion annual subsidy flows not to low-income homeowners but to second homes, rental properties, high-value buildings, and Florida coastal owners. The finding reframes the political argument for preserving the program's glidepath, and shapes how the NFIP book will reprice over the next decade.
The report comes from Neptune Flood Research Group, tracking NFIP pricing across five years of Risk Rating 2.0. FEMA launched that system in October 2021, moving away from flood-zone-based pricing toward property-specific, full-risk rates. New policies were repriced immediately. Existing policyholders move toward full risk under an 18 percent annual cap, which creates the glidepath where the remaining subsidy lives.
The reform is working as designed. Over half of NFIP policies now pay full-risk premiums, up from one-third in December 2022, according to the report. The 1.5 million policies still below full risk (42 percent of the program) carry a combined annual subsidy of roughly $2.6 billion.
The distribution of that subsidy is what the report identifies as the structural problem.
Non-primary properties, such as second homes, rentals, and businesses, hold 42 percent of subsidy dollars on just 28 percent of policies. Properties with a replacement cost above $1 million are 4 percent of the book but account for at least 17 percent of the subsidy.
The most-subsidized segment is non-primary single-family homes worth $1 million or more. Neptune Flood Research Group found that 68 percent of them pay below their full-risk cost, and in aggregate they pay less than half that cost.
The poorest fifth of census tracts hold the smallest share of subsidy dollars of any income quintile - 15.8 percent, or about $419 million per year. That group also receives the shallowest effective discount, at 27 percent below full risk against 33 to 36 percent for the upper three quintiles. The subsidy tracks property value, tenure, and geography, not financial need.
Tenure is the clearest predictor. Customers with five or more years in the program, or those who joined before Risk Rating 2.0, are 62 percent of the book but hold more than 83 percent of remaining subsidy dollars. That cohort receives about $2.2 billion per year.
The NFIP's $22.5 billion debt to the US Treasury and its declining enrollment have already drawn attention on Capitol Hill, with senators flagging steeper coverage drops in lower-income communities as Risk Rating 2.0 raises costs.
The geographic concentration is just as stark. Florida holds roughly $1.25 billion of the annual subsidy, or about 48 percent of the national total, across 507,700 subsidized policies. The mean gap there is $2,474, which is 43 percent above the national average, according to the Neptune report.
At the county level, the picture is hyper-local. Lee and Collier counties, which were ground zero of Hurricane Ian in 2022, together account for $422 million, about 16 percent of the national total. In Collier alone, 76.8 percent of policies are subsidized at a mean gap of $4,457. The top 25 counties nationally hold 57 percent of the subsidy, and 13 of them are in Florida.
The Neptune report projects the subsidy will halve in roughly 2.6 to 3.8 years under current law. It falls below $500 million sometime between 2032 and 2034. As the runoff proceeds, Florida's share of the remaining book grows. By mid-2034, its portion is projected to climb from 47 percent to 60 percent.
Two in-force examples from the report put numbers to that trajectory. A Florida AE-zone single-family home currently paying $856 per year faces a full-risk cost of $10,200. A Florida AE-zone condo association paying $5,999 faces $71,556.
The glidepath's runoff has come partly from repricing and partly from attrition. Of the $2.5 billion in annual subsidy closed since October 2021, roughly 42 percent closed because the policyholder left the program, not because their price caught up to full risk.
The Neptune report notes that the data cannot confirm whether departing policyholders found private coverage or went uninsured. That distinction falls on agents and brokers working in high-exposure markets. Subsidized policies lapse at 7.4 percent annually against 13.1 percent for the full book, which means the deepest discounts are the least likely to leave voluntarily.
As the subsidy concentrates further into its Florida tail, the private flood market is the nearest alternative for policyholders facing steep increases. The growing private flood insurance market has expanded considerably since Risk Rating 2.0, but whether departing NFIP policyholders are landing in private coverage or going bare remains an open question for agents working flood-exposed books.
The NFIP caps residential building coverage at $250,000. In markets like Fort Myers and Naples, where replacement costs often run well above that figure, the gap between federal limits and actual exposure is where private flood carriers have moved to compete directly.
The Neptune report recommends pairing the glidepath's phase-out with targeted, means-tested assistance for low-income primary residences. The report prices that carve-out at $214 million per year, about 8 percent of the current subsidy total.
