A catastrophe savings account is a state-authorized, tax-advantaged savings account that lets a homeowner set aside money for insurance deductibles and uninsured losses from a natural disaster. Only three states currently offer them: Mississippi, South Carolina, and Alabama. If you live in one of those states and own your home, you can deduct contributions from your state taxable income, let the interest grow free of state tax, and withdraw the money tax-free when a declared disaster hits.
Where These Accounts Exist
Catastrophe savings accounts are not a federal program. They exist only where a state legislature has created them. Mississippi’s program took effect January 1, 2015. South Carolina and Alabama have their own statutes authorizing the same type of account. As of 2026, no other state offers one.
A federal version has been proposed. Senator Rick Scott reintroduced the READY Accounts Act in June 2025, which would create a nationwide equivalent, but the bill had not passed as of early 2026. Until it does, the tool is available only to residents of those three states.
Who Can Open One
You have to be a state income taxpayer who owns a principal residence in the state where you’re opening the account. You also need a homeowner’s insurance policy covering catastrophic events such as hurricanes, floods, and windstorms, or you have to qualify as self-insured. Each taxpayer is limited to one account.
The account itself has to be a regular savings or money market account at a state or federally chartered bank, labeled “Catastrophe Savings Account,” and kept completely separate from your other money. You cannot mix CSA funds with a checking account, another savings account, an IRA, or anything else.
How Much You Can Contribute
The contribution cap depends on your homeowner’s insurance deductible, or on whether you carry insurance at all:
- If your deductible is $1,000 or less, the maximum you can put in the account is $2,000.
- If your deductible is above $1,000, the maximum is the lesser of $15,000 or twice your deductible.
- If you’re self-insured, the maximum is the lesser of the value of your home or a statutory ceiling. That ceiling is $250,000 in South Carolina and Alabama, and $350,000 in Mississippi.
These are lifetime caps on the balance, not annual limits. You can fund the account in one deposit or build it up over several years until you reach the cap.
The Tax Benefits
The tax breaks apply only at the state level. Contributions reduce your state taxable income: Mississippi excludes them from taxable gross income, while South Carolina and Alabama allow a deduction in computing state taxable income. Interest earned inside the account is also excluded from state income tax. Withdrawals used for qualified catastrophe expenses are not taxed.
None of this changes your federal tax picture. Contributions, interest, and withdrawals are still treated normally under federal rules.
Qualified Withdrawals
Withdrawals come out tax-free only when the money pays for qualifying expenses tied to an officially declared disaster. A storm that damages your roof but doesn’t trigger a formal emergency or disaster declaration will not qualify.
Once a qualifying event has occurred, the account can pay for:
- Your homeowner’s insurance deductible.
- Repair and reconstruction costs your insurer doesn’t reimburse.
- Other uninsured losses, including damage to the structure or essential components of the property.
Tax-free treatment applies only up to your actual qualifying expenses for the year. Withdraw more than you spent on qualifying costs, and the excess is a taxable distribution.
Penalties for Non-Qualified Withdrawals
Pull money out for anything other than a qualifying expense and two things happen. The withdrawn amount gets added back to your state taxable income, so you lose the deduction you took when you contributed. On top of that, you owe a 2.5% penalty tax on the taxable portion, reported on your state return for the year of the withdrawal.
When the Penalty Doesn’t Apply
All three states waive the 2.5% penalty in a few situations, though ordinary state income tax still applies to the distribution:
- You no longer own a qualifying home.
- You set up the account as a self-insured taxpayer and have reached age 70.
- The account holder has died. In Alabama, a surviving spouse who inherits the account isn’t taxed on the rollover; the money is included in income only when the surviving spouse later withdraws it or dies.
Alabama adds a catch: once you take a non-taxable distribution under one of these exceptions, you can’t make further CSA contributions. That’s rarely a concern after a sale or a death, but it matters if you’re self-insured, approaching 70, and thinking about a partial withdrawal.
Keep Your Records
Banks that hold these accounts are not required to check how you spend the money. If your state revenue department audits your return, proving that each withdrawal paid for a qualifying expense is your job. Hold on to the disaster declaration, contractor invoices, repair receipts, insurance claim documents showing the deductible, and proof of payment. The goal is to match each withdrawal to a specific expense, not just show that you spent about the right amount on repairs.
Protection From Creditors
Money in a catastrophe savings account gets legal protection that an ordinary savings account doesn’t. Under the Mississippi and South Carolina statutes, CSA funds are not subject to attachment, levy, garnishment, or other legal process, so creditors generally cannot reach the balance to satisfy a judgment or debt while the money sits in the account.
