Credits and breaks for Mississippi families: $1,500 a dependent, 25% of the care credit, and the MACS deduction

The first thing a Mississippi family should know is what the state does not do. There is no Mississippi earned income credit and no Mississippi child tax credit, and every credit the state does offer is nonrefundable: it can take the Mississippi tax to zero and no further. A family that gets $7,000 back from the federal EITC and child tax credit gets nothing from Mississippi beyond its own withholding. What Mississippi does instead is modest and fixed: $1,500 off taxable income for each dependent, $8,000 instead of $6,000 for a single parent filing as head of family, a $3,400 standard deduction for that parent, and the first $10,000 of taxable income at 0%. A single parent with two children owes nothing on the first $24,400 of wages; a married couple with two children, nothing on the first $29,600, or $39,600 if both work and they file combined. Above that the rate is 4.0% for 2026.

Because Mississippi builds its own income rather than starting from a federal number, the federal child tax credit, the federal EITC, the federal dependent care credit and the federal standard deduction have no direct effect on Form 80-105. Two of them have an indirect one: the Mississippi dependent care credit is figured as a percentage of the federal credit, and federal adjusted gross income is the test for whether you get it.

Dependents: $1,500 each

Each dependent other than yourself or your spouse adds $1,500 to the exemption on Form 80-105. A married couple with two children claims $12,000 plus $3,000; with four children, $12,000 plus $6,000. The dependent exemption has no age cutoff of its own and no phase-out at any income; a household earning $400,000 claims the same $1,500 per child as one earning $40,000. Mississippi uses the dependents claimed on the federal return, so the question of which divorced parent claims the child is settled federally and follows here. The $1,500 extra exemptions for age 65 and for blindness are for the taxpayer and spouse only, never for a dependent. The filing threshold rises by $1,500 per dependent too, so a single parent with two children need not file until gross income passes $11,300.

Head of family: the entire year

Mississippi’s version of head of household is called head of family, and it is worth having: an $8,000 exemption instead of $6,000, a $3,400 standard deduction instead of $2,300, and the $1,500 for each dependent on top. The definition is a taxpayer who is single and maintains a household, with a dependent “living in the home with you for the entire year.” That is stricter than the federal rule, which asks for more than half the year. A parent whose child moved in during the year, or a taxpayer who supports a parent living in her own home, can be federal head of household and Mississippi single (verify). Software that copies the federal status does not check this. The $8,000 head-of-family exemption already presumes one dependent; the $1,500 is added for that dependent and for each additional one, so a single parent with two children claims $8,000 plus $3,000.

Two earners: file combined

The single biggest break for a married couple in Mississippi is not a credit. It is the combined return. The first $10,000 of taxable income is taxed at 0% per taxpayer, not per return, and when both spouses have income each one’s goes in its own column with its own zero bracket. The couple splits the $12,000 exemption, the dependent exemptions and the deduction between the columns however they like. The result is $20,000 of taxable income at 0% instead of $10,000, which is $400 at 4.0%. A couple where one spouse stays home files joint and gets one zero bracket; there is no way around that, and no credit to make it up. The arithmetic is worked in How Mississippi income tax works.

The dependent care credit: 25%, under $50,000

Mississippi’s child and dependent care credit is 25% of the federal credit claimed on federal Form 2441, allowed only when federal adjusted gross income is $50,000 or less. One dollar over, no credit. The federal credit at that income is 20% of up to $3,000 of expenses for one child or $6,000 for two or more, so the most the Mississippi credit can be for a family with two children in care is 25% of $1,200, or $300, and for one child $150. It is nonrefundable with no carryover, claimed on Form 80-401 with the federal form attached. The $50,000 test is federal AGI, which includes the parent’s wages before any Mississippi exemptions, so a two-earner couple with children in daycare is usually over the line and gets nothing; the credit is built for single parents and one-earner households. The 2026 Legislature revised the employer side of child care, the credit a business can take for providing or paying for employee child care, in Senate Bill 2867; that is the employer’s credit, not the family’s.

Every Mississippi credit is nonrefundable. The exemptions and deductions reduce taxable income; the credits reduce the tax that is left.

MACS and MPACT: the deduction the federal return never asks about

Mississippi deducts contributions to its own 529 plan, the Mississippi Affordable College Savings program, up to $10,000 a year on a single or head-of-family return and $20,000 on a joint or combined return, on line 57 of Form 80-105. Contributions must be made by April 15 without regard to extensions. Payments on a Mississippi Prepaid Affordable College Tuition contract are deducted in full on line 56. Contributions to another state’s 529 plan get nothing. At 4.0%, a family that puts $5,000 a year into MACS saves $200 of Mississippi tax, and a grandparent who opens a MACS account for a grandchild takes the deduction on the grandparent’s return. Because the federal return has no line for 529 contributions, this is the deduction most often left off; the preparer has to ask. Withdrawals for qualified education are tax-free federally and in Mississippi. There is no Mississippi credit or deduction for K-12 tuition, for college tuition paid out of pocket, or for student loan interest, which is a federal adjustment Mississippi does not list among its own (verify).

Adoption

A family that adopts takes a credit of up to $10,000 for a child who lived in Mississippi before the adoption and up to $5,000 for a child from elsewhere, beginning in the year the adoption is final, on Form 80-401. Unused credit carries forward five years, which matters because the whole credit will usually exceed one year’s tax: a family with $60,000 of income and two children owes roughly $1,000 of Mississippi tax, so a $10,000 credit takes several years to use.

Child care, kiddie tax and household help

Mississippi has no kiddie tax of its own; a child with investment income files a Mississippi return in the child’s own name once gross income passes $8,300, and the first $10,000 of taxable income is at 0%, so a child’s brokerage account rarely owes anything. A family that pays a nanny or housekeeper directly handles Mississippi withholding and unemployment tax through the Department and the Mississippi Department of Employment Security the same way as any employer; the federal Schedule H has no Mississippi counterpart on the income tax return.

What trips people up

• Expecting a state EITC or child credit. There is none, and nothing Mississippi offers is refundable.
• Head of family copied from the federal head of household when the dependent did not live in the home the entire year.
• The dependent care credit claimed with federal AGI over $50,000, or missed because the preparer did not know Mississippi had one.
• A joint return when both spouses work; the combined return is worth up to $400.
• A MACS or MPACT contribution nobody mentioned.
• A contribution to another state’s 529 plan deducted as if it were MACS.
• The adoption credit taken all in one year and the carryforward lost.
