Short answer
State Social Security tax is a state-by-state rule, not a national rule.
IRS Publication 915 explains federal Social Security taxation. State treatment is separate. AARP and Tax Foundation state-tax sources show that some states tax Social Security in some form while many do not, often with income-based exemptions.

The retirement-plan layer turns the rule into cash flow: what comes in, what goes out, what is taxable, and what can change later.

The family layer matters because the same rule can feel different when it affects a spouse, adult child, home, health care, or dream budget.
