2027 Mississippi Tax Changes: the published rate path and filing choices
Mississippi did not eliminate its individual income tax for 2027. The Department of Revenue’s published 2025–2027 schedule shows a 3.75% rate applied to taxable income over $10,000. The Governor’s House Bill 1 update outlines a path toward 3% by 2030. This guide clarifies the path and organizes resident and nonresident filing choices.

Core answer
Short answer: Mississippi still has an individual income tax for 2027. According to the Department of Revenue’s published 2025–2027 schedule, taxable income in excess of $10,000 for tax year 2027 is taxed at 3.75%. That schedule addresses the rate on the amount above $10,000; it does not, by itself, rewrite how taxable income is computed or whether other amounts are taxed differently. Separately, the Governor’s House Bill 1 announcement describes a phased path toward a 3% rate by calendar year 2030 and potential later reductions. Those later steps are not the 2027 rule. Your return requirement still depends on residency and whether you had Mississippi‑source income. Combined filing options, retirement income treatment, and estimated payments should be handled using the 2027 instructions when released.
What the published Mississippi 2027 rate schedule says and what it does not say
As of August 21, 2026, Mississippi’s Department of Revenue has a published 2025–2027 schedule stating that tax year 2027 taxable income in excess of $10,000 is taxed at 3.75%. That is the clearest, current statement about how the 2027 rate applies to the portion of taxable income above that level. It confirms there is still a Mississippi individual income tax in 2027. It also means you should read “taxable income” exactly as Mississippi defines it in the annual instructions, which arrive closer to filing season. The schedule is a rate reference, not a full return guide, so you will still need the 2027 forms and instructions when they are published.
What the schedule does not do is eliminate the tax, nor does it independently set every detail of how your Mississippi taxable income is built. It does not publish a complete bracket table, define deductions, name credits, or establish calculation worksheets. It simply states that for 2027, taxable income in excess of $10,000 is taxed at 3.75%. Other pieces of the tax calculation—such as how Mississippi starts from federal figures, applies Mississippi adjustments, and then compares deductions—remain governed by the 2027 instruction booklet once issued by the Department of Revenue.
It is also important to distinguish the Department’s schedule from broader policy announcements. The Governor’s House Bill 1 update describes a phased path toward a 3% rate by calendar year 2030 and mentions possible later reductions. That is a road map, not the operative 2027 computation. The 3.75% figure on taxable income over $10,000 is the rate reference for 2027 that Mississippi has already published. Any future step-downs will appear in later-year guidance and should be read directly from the Department’s updates when each year’s instructions and schedules are released.
The phrase “taxable income in excess of $10,000” is about the base to which the 3.75% rate applies. It is not the same as your wages, gross receipts, or adjusted gross income. Mississippi taxable income is an after-adjustment, after-deduction figure determined under Mississippi’s rules. How income at or below $10,000 of taxable income is treated in 2027 depends on the full set of Mississippi instructions and worksheets. Do not assume treatment for amounts at or below that level without the official 2027 instruction booklet in hand.
Finally, remember that residency and source rules decide whose income is measured by Mississippi at all. Residents look to Mississippi taxable income across the year, while nonresidents generally look only to their Mississippi-source taxable income, and part-year residents split periods. The published rate schedule applies to the portion of Mississippi taxable income above $10,000 after those residency and source determinations are made. For now, bookmark the Department’s rate schedule and be ready to fold in the 2027 forms, definitions, and examples when they are posted closer to filing season.
Who may need a Mississippi return: resident, nonresident, part-year, and Mississippi-source income paths
Start with your residency status for 2027. Mississippi generally treats you as a resident when Mississippi is your primary home and you keep significant ties here. Nonresidents live elsewhere for the year. Part-year residents moved in or out during 2027. The Department of Revenue’s annual instructions explain the tests and examples that sort these categories. If you are a resident, your starting point typically includes income from all sources, then Mississippi allows adjustments and credits as the state’s rules provide. If you are a nonresident or part-year resident, you instead focus on the Mississippi-source portion and the Mississippi period, respectively.
Mississippi-source income often includes wages for work physically performed in Mississippi, business or gig income from activities carried on in the state, rents and royalties from Mississippi property, and gains from selling Mississippi real estate. If you live in another state but travel into Mississippi to perform services, those wages are often Mississippi-source for the days worked here. Likewise, a partnership, S corporation, or LLC doing business in Mississippi may flow Mississippi-source income to you on a schedule from the entity. The nonresident instructions detail the allocation and apportionment steps used to compute Mississippi-source taxable income.
Part-year residents follow a split-year approach. For the months you were a Mississippi resident, income is treated like that of a resident. For the months you were a nonresident, only Mississippi-source income is in play. The 2027 instructions will show how to mark the moving date, report totals, and allocate federal figures between periods if needed. Keep move-in and move-out documentation, such as lease start and end dates, home sale or purchase records, and employer location records for workdays. Those items become the backbone of your Mississippi residency timeline if questions arise during filing.
Remote and hybrid work require special attention. In general, Mississippi focuses on where the services are performed. If you telework entirely from your home outside Mississippi for a Mississippi employer, the wages may be sourced to your home state rather than Mississippi; if you commute in part-time, the Mississippi days can create Mississippi-source wages. Because sourcing rules are detailed and facts matter, rely on the 2027 nonresident and part-year instructions for examples, definitions, and any updated guidance affecting cross-border telework arrangements.
A practical decision path looks like this: 1) determine your 2027 residency category using the Department’s definitions; 2) list all income types and identify which items are Mississippi-source; 3) check whether you had Mississippi tax withheld or made estimated payments; 4) review whether you must file to settle up, to claim a refund, or to support credits; and 5) if married, decide whether to use a combined return and how to allocate each spouse’s Mississippi income. Each step relies on the 2027 Mississippi instruction booklet, which will clarify thresholds, forms, and example calculations once released.
How taxable income, exemptions, deductions, and filing status work together
Mississippi taxable income is not the same as federal adjusted gross income. The Department of Revenue’s annual instructions typically start from a federal figure and then walk you through Mississippi additions and subtractions to reach a Mississippi base. After that, deductions and exemptions are applied as Mississippi allows for the year. The end product—Mississippi taxable income—is what the 2027 rate schedule references when it says taxable income in excess of $10,000 is taxed at 3.75%. Because Mississippi can decouple from some federal items, always follow the Mississippi-specific line instructions for 2027.
Deductions matter because they change how much of your income becomes Mississippi taxable income. Mississippi offers a choice between a state standard deduction and itemized deductions based on Mississippi’s rules. Some federal itemized amounts may be limited or adjusted under Mississippi law, and some expenses allowed federally might not be allowed the same way for Mississippi. The 2027 instructions will show whether you should itemize for Mississippi, even if you take the federal standard deduction, or vice versa. Run both approaches using the Mississippi worksheets once they are published, and keep receipts to support the option you choose.
Filing status also affects the Mississippi calculation. In general, your state filing status aligns with your federal status, but Mississippi provides a combined return option for many married couples. Under that approach, spouses often compute Mississippi tax on each person’s separate Mississippi taxable income within one return. This can matter where one spouse has little or no Mississippi-source income, or where deductions differ between spouses. The 2027 booklet explains how to elect combined filing, how to separate income and deductions, and how credits are applied. Review those pages carefully before choosing a status for 2027.
Credits sit alongside deductions and can affect the final Mississippi tax due or refund. A common example is a credit for income tax paid to another state on income that Mississippi also taxes. The 2027 instructions will explain which forms and statements to attach and how to calculate any limitation. Other credits may exist in Mississippi’s code and instructions, sometimes for specific income types or payments made during the year. Because credits can interact with residency and sourcing, gather other states’ returns, W‑2s that show state withholding, and any pass‑through statements early so you can apply credits correctly on the 2027 Mississippi return.
Putting it together, a Mississippi 2027 calculation typically follows this flow: start from your federal figure, apply Mississippi additions and subtractions, choose between Mississippi standard or itemized deductions, select your filing status (including, if applicable, a combined return with separate spouse computations), and apply any eligible credits. The result is Mississippi taxable income and final tax. Only then does the published 3.75% rate on taxable income in excess of $10,000 come into play. Because each step depends on the official 2027 instructions, avoid using prior-year rules as a substitute and watch for the Department’s updates.
Retirement income, Social Security, combined returns, and common questions
Mississippi’s treatment of retirement income is a frequent point of confusion. Historically, Mississippi has treated certain retirement distributions differently from wages, and many retirees see different outcomes at the state level than at the federal level. Social Security benefits are also handled under Mississippi’s own rules. For 2027, rely on the Department of Revenue’s instructions to confirm what retirement distributions are included in, or excluded from, Mississippi taxable income and how to document them. If you receive 1099‑R statements, keep them with any plan descriptions so you can follow Mississippi’s step‑by‑step guidance accurately when it is issued.
If you are a retiree living outside Mississippi but you own Mississippi rental property or a business interest operating here, you may need to file a nonresident Mississippi return to report that Mississippi‑source income. The published 3.75% rate for 2027 still applies to Mississippi taxable income in excess of $10,000 as determined under Mississippi rules. Retirees should also review estimated payments if their Mississippi‑source income is not subject to Mississippi withholding. The Department’s online payment options and vouchers allow you to prepay during the year so that your 2027 filing is closer to even when the return is prepared.
Married couples often ask about Mississippi’s combined return option. Many couples can file a single combined return and calculate Mississippi tax on each spouse’s separate Mississippi taxable income within that return. This can be useful when only one spouse has Mississippi-source income or when the spouses’ deductions fall differently. The 2027 instruction booklet will explain how to elect the combined approach, how to allocate income, adjustments, and deductions between spouses, and how to attach any schedules that support the separate calculations inside the combined filing. Keep good records by spouse to make the allocation easier and clearer.
Another common question is how Mississippi treats out‑of‑state pensions and annuities. Treatment depends on Mississippi rules and the nature of the payment. If an out‑of‑state plan withholds another state’s tax from your distribution, you might still need to look at Mississippi’s 2027 rules to decide whether any portion belongs in Mississippi taxable income and whether a credit is available. Keep every year‑end statement showing state tax withheld, along with payor addresses and plan details. The Department’s instructions will show how to enter these items and whether documentation is required with the return.
Finally, Social Security recipients want to know whether benefits change their Mississippi filing needs. In Mississippi, Social Security benefits are addressed under state rules that have traditionally differed from federal taxable treatment. For 2027, check the DOR’s guidance to confirm whether Social Security is included in your Mississippi taxable income and how it interacts with other retirement income and deductions. If you receive both Social Security and Mississippi‑source rental or business income, you may still need a Mississippi return even if your benefits themselves are not taxed the same way. Keep SSA‑1099 forms with your records for the 2027 file.
Withholding, estimated payments, filing timing, and records to organize
Withholding is your first opportunity to match 2027 Mississippi tax to your situation. If you are an employee, review your Mississippi withholding elections with your employer before year‑end and again when the 2027 instructions arrive. Consider your expected Mississippi‑source wages, bonuses, and equity income. The Department’s published 3.75% rate on taxable income in excess of $10,000 informs planning but does not replace the official tables and worksheets your employer will use. If you experienced a large refund or balance due for 2026, that is a signal to revisit your 2027 elections and spread any adjustments over the remaining pay periods.
Self‑employed individuals, landlords, and investors with Mississippi‑source income should evaluate quarterly estimated payments for 2027. Mississippi provides ways to make those payments electronically or by voucher. The Department of Revenue’s 2027 guidance will show due dates and any calculation worksheets. While you wait, sketch your 2027 Mississippi‑source income, subtract expected Mississippi deductions, and assess whether significant Mississippi taxable income will remain above $10,000. If so, plan periodic prepayments so that your year‑end Mississippi balance is manageable and interest is minimized. Update your plan when the Department posts 2027 instructions and any updated worksheets.
Filing timing matters too. Mississippi publishes an annual calendar with the opening of the filing season, the return due date, extension options, and payment cutoffs. An extension to file, if available, does not extend the time to pay. If you need extra time to file, consider making a reasonable Mississippi payment with the extension so that you reduce interest on any unpaid 2027 tax. Save the confirmation for any online payments. If you file early to claim a refund, keep in mind that you may need to wait for wage and withholding data to be available for verification.
Organized records make the Mississippi calculation smoother. Keep W‑2s showing Mississippi wages and state withholding, 1099s that report Mississippi‑source payments, K‑1s from pass‑through entities operating in Mississippi, rent ledgers and mortgage statements for Mississippi property, and broker statements for any real estate sales located here. Maintain proof of residency, such as lease agreements, home closing documents, driver’s license updates, and school enrollment records for dependents. Document days worked in Mississippi if you are a nonresident or a part‑year resident with hybrid or travel assignments.
Finally, keep copies of prior Mississippi returns and any letters from the Department of Revenue, plus confirmations for estimated payments and employer withholding changes. If you plan to use the combined return option for 2027, begin keeping spouse‑by‑spouse logs of income, adjustments, and deductions now so that allocation is straightforward at filing. Store SSA‑1099s, 1099‑Rs, and any pension statements with your Mississippi file. If you claim a credit for tax paid to another state, keep the other state’s return and proof of payment. These items make the 2027 Mississippi filing faster and more accurate.
Connect Mississippi’s rate path to the federal 2027 decision that comes next
Mississippi’s published 2027 rate schedule stands alongside federal changes that may shape your state base. Mississippi typically begins from a federal income figure and then makes Mississippi‑specific adjustments. That means federal shifts to income definitions, above‑the‑line deductions, or itemized deductions in 2027 can flow through to your Mississippi starting point. The Department’s 2027 instructions will state exactly how Mississippi conforms for the year. As you plan, track the Mississippi rate reference—3.75% on taxable income in excess of $10,000—and be prepared for Mississippi to publish any adjustments needed to align with federal changes.
If Congress changes federal itemized deductions or the standard deduction for 2027, the Mississippi choice between state standard and state itemized deductions could look different than in 2026. Because Mississippi’s decision is made under Mississippi rules, you should run both options using the Mississippi worksheets once they are posted. The result can affect whether your Mississippi taxable income rises above $10,000 and how much sits above that level. That, in turn, affects how much of your income is exposed to the 3.75% rate referenced in the Department’s schedule for tax year 2027.
Employer withholding will also need a tune‑up if federal and Mississippi rules shift. Your federal Form W‑4 choices influence your paycheck, but Mississippi uses its own employee withholding elections and tables. When the Mississippi 2027 tables are published, make sure your state withholding takes into account any new federal amounts that flow into your state calculation. This coordination helps avoid a large Mississippi balance due or an excessive refund when you prepare your 2027 return. Revisit elections after bonuses, equity events, or job changes.
Business owners and pass‑through investors should watch both federal and Mississippi instructions. Federal depreciation, expensing, and partnership basis rules can alter the federal K‑1 amounts that Mississippi uses as a starting point. Mississippi may accept, adjust, or decouple from some items. The 2027 Mississippi instructions will outline the state‑level additions and subtractions to apply to those federal figures. If your Mississippi‑source share is significant, consider a quarterly planning cadence so you can time purchases or distributions with a clear view of both federal and Mississippi consequences for 2027.
Looking beyond 2027, the Governor’s House Bill 1 announcement describes a path toward a 3% Mississippi rate by calendar year 2030 and mentions possible later reductions. Those later steps are policy direction and do not replace the published 2027 schedule. Treat 2027 as its own year: use the Department’s rate reference and instructions when posted, confirm how federal changes feed into your Mississippi base, and then revisit the longer‑term path each year as Mississippi publishes the next round of forms, schedules, and guidance.
