What bank account can the IRS not touch?

The IRS can generally levy any account in your name for unpaid taxes, but some funds are protected, like certain disability payments or Social Security (though some can be taken), and funds in an irrevocable trust or accounts not directly in your name (like some business or trust accounts) are harder to seize. Certain income sources are never taxed, like some veterans' benefits, child support, and welfare, but these aren't usually held in traditional bank accounts. The key is that the IRS targets your assets for your tax debt, so protecting funds by legally changing ownership or ensuring they are designated as non-taxable income is how they become untouchable by levy.
