Mississippi for retirees: nothing on retirement income, and the early-distribution trap

A Mississippi retiree living on Social Security and a pension has no Mississippi gross income. The state’s instructions say it in four words: retirement income is “exempt in total.” Social Security and railroad retirement benefits, pensions from federal, state and private retirement systems, military retirement, PERS, 401(k), 403(b) and IRA distributions taken at retirement, none of it goes on the return, and a household with nothing else coming in does not have to file at all. What Mississippi does tax is what a retiree earns outside the retirement system: interest, dividends, capital gains, rent, and wages from a job in retirement, at 4.0% above the first $10,000 of taxable income. And it taxes one kind of retirement-plan money: distributions that federal law treats as early. That exception is small for most people and large for anyone converting to a Roth before 59½.

Because Mississippi defines its own income rather than copying a federal line, there is no “subtraction” to claim and nothing to carry from the 1040. Exempt income is simply left off Form 80-105. The 1099-R still arrives, and the distribution code in box 7 is what decides where it goes: a code 7 normal distribution stays off the return; a code 1 or 2 early distribution goes on line 46, “taxable pensions and annuities.” Software that copies every 1099-R onto the state return puts exempt money back into Mississippi income, and that is the most common error on a retiree’s Mississippi return.

What is exempt

The Department’s regulation adds that “retirement allowances” do not include income from investments in stocks, bonds, securities or real property. The retirement account is exempt; the brokerage account next to it is not.

There is no age test and no dollar cap. A retired physician with a $200,000 pension and a retired teacher with a $20,000 one are treated the same: zero. The exemption does not depend on where the pension was earned, so a pension from a former employer in another state is just as exempt once you live here. Nor does it depend on Mississippi residency when the money was contributed; the test is where you live when it is paid.

The early-distribution exception, and Roth conversions

The instructions carve out one group: “pensions and annuities that are taxable as early or excess distributions” under federal law do not qualify for the exemption. The regulation says the same and adds that although those amounts are taxed, “there is no early withdrawal penalty for state purposes.” So a 45-year-old who cashes out a 401(k) pays the federal tax and the federal 10% penalty, and pays Mississippi 4.0% on the distribution with no state penalty on top. The code on the 1099-R is the practical test: a 1 or a 2 means Mississippi income.

A Roth conversion is a distribution from a traditional IRA deposited in a Roth, and the 1099-R for it carries code 7 if the owner is 59½ or older and code 2 if younger. The Department has published no guidance on conversions. Practitioners follow the codes: a conversion at 62 is a normal distribution from a retirement system, exempt in total, and costs federal tax only; a conversion at 55 is an early distribution and costs federal tax plus Mississippi tax at 4.0%. For a resident who intends to convert, that makes the first year after 59½ the obvious year to start. Converting $100,000 at 58 instead of at 60 costs about $4,000 of Mississippi tax that waiting would have avoided, assuming other taxable income already fills the $10,000 zero bracket.

The federal side is unchanged by any of this. A conversion raises federal AGI, which can make more Social Security taxable, raise Medicare premiums two years later through IRMAA, and shrink the federal senior deduction, which phases out above $75,000 of modified AGI single and $150,000 joint. Mississippi’s indifference to the conversion after 59½ is a reason to convert here rather than after a move to a state that taxes it; it is not a reason to ignore the federal arithmetic.

The federal senior deduction, and why it does nothing here

The $6,000 federal deduction for people 65 and older, in effect for 2025 through 2028, comes off after federal adjusted gross income. Mississippi never uses federal AGI or anything below it, so the deduction neither reaches the state return nor needs to be added back. The same is true of the larger federal standard deduction for age. Mississippi’s own break for age is the extra $1,500 exemption for a taxpayer or spouse who is 65 or older on the last day of the year (a person is 65 on the day before the birthday), worth $60 of tax at 4.0%. For a couple both over 65 the exemptions are $12,000 plus $3,000, and with the $4,600 standard deduction they can have $19,600 of taxable interest, dividends, gains and wages before anything is taxed, and then the first $10,000 of taxable income is at 0% anyway. In practice a retired couple with under about $29,600 of non-retirement income owes nothing.

Property tax relief at 65

Mississippi gives seniors no credit on the income tax return and no rebate. The help is on the property tax bill, and it comes from the county tax assessor, not the Department of Revenue. Homes are assessed at 10% of true value. Every owner-occupant who applies gets the regular homestead exemption, a credit against the tax on the first $7,500 of assessed value limited to $300 of tax saved. At 65, or when 100% disabled, that becomes the additional exemption: the first $7,500 of assessed value is exempt from all ad valorem taxes with “no dollar limit” on the tax saved. Since $7,500 assessed is $75,000 of market value, a 65-year-old whose home is worth $75,000 or less owes no property tax on it, and everyone else’s bill is figured on the value above $75,000. On a $160,000 house, $16,000 assessed, in a county levying 100 mills, the bill falls from $1,600 to $850 (verify millage). A disabled veteran with a 100% service-connected rating, or the unremarried surviving spouse, is exempt entirely (verify).

The application is filed once at the county tax assessor’s office, between January 1 and April 1, and must be refiled when something changes: turning 65, a death, a sale, a marriage. The assessor will ask for Mississippi vehicle tags on every car in the household and will expect a Mississippi income tax return to have been filed if one was required. A retiree who moves in and keeps the former state’s tags will be turned down. There is no senior freeze, no income-based circuit breaker and no deferral program.

Estate and inheritance

Mississippi requires no estate tax return for anyone dying on or after January 1, 2005, and has no inheritance tax and no gift tax. The federal estate tax, with its $15 million exemption for 2026, is the only one to plan around, and for nearly every household it does not apply.

Withholding and estimated payments

Since retirement income is not taxed, Mississippi withholding on a pension or IRA distribution serves no purpose, and most payers do not withhold it; a retiree who sees Mississippi tax withheld on a 1099-R should file to get it back. The retirees who need to watch estimated payments are the ones with large taxable brokerage accounts, rental income, a sale with a big gain, or an early Roth conversion, because none of that is withheld on. Estimates on Form 80-106 are required when withholding covers less than 80% of the year’s tax and the tax is over $200, due April 15, June 15, September 15 and January 15; underpayment draws interest at 1/2% a month. See How Mississippi income tax works.

Moving in, moving out

Federal law since 1996 bars any state from taxing the retirement income of someone who no longer lives there. A retiree who moves into Mississippi stops paying the former state’s tax on the pension the day residency changes, and Mississippi taxes none of it. The reverse holds too: a Mississippian who retires elsewhere starts paying the new state’s rules on the same pension, and the Mississippi exemption does not travel. The move-year return is Form 80-205, which taxes only income received while a resident and prorates exemptions and deductions by the Mississippi share of total income; pension payments received before the move are the former state’s, those after are Mississippi’s and exempt.
