Credits and breaks for Missouri families: the Working Family Tax Credit, 529 deposits, and what is missing

A family’s Missouri return looks almost exactly like a single person’s. There is no exemption for a child, no state child tax credit and no credit for day care. The standard deduction is the federal one, $32,200 married filing combined and $24,150 head of household for 2026, and the tax is 4.7% of what is left. Missouri adds three things for families. The Working Family Tax Credit is 20% of the federal earned income credit, but it only reduces Missouri tax, never produces a refund, so a family whose Missouri tax is already low loses most of it. Contributions to a 529 college savings plan, Missouri’s MOST or any other state’s, are deducted up to $8,000 per taxpayer or $16,000 on a combined return, worth up to $752. A head of household gets a $1,400 additional exemption on top of the standard deduction. The rest of what a Missouri family saves comes from the federal return flowing through: pre-tax child care through a dependent care account, health savings account deposits, and retirement contributions all reduce federal AGI, and Missouri starts from federal AGI.

One thing works against families. Missouri lets you deduct part of your federal income tax, and the federal child tax credit reduces that federal tax. A family with two children and $2,760 of federal tax after a $4,400 child tax credit deducts 15% of $2,760, not 15% of $7,160. The credit that saved $4,400 federally cost about $31 in Missouri. It is a small number, but it surprises people who expected the child credit to help on both returns.

The Working Family Tax Credit

Form MO-WFTC computes 20% of the federal earned income credit shown on your Form 1040, and the result goes on MO-1040 line 44. The 2025 form states 20%; the statute reached 20% through a revenue trigger and does not step back down, so 20% is expected for 2026, with the form to come (verify). You must be a Missouri resident, your filing status must be single, head of household, qualifying widow(er) or married filing combined, and you must have been allowed the federal credit. Married filing separately does not qualify, and neither does anyone claimed as a dependent. The 2025 form carries an investment income limit of $4,400 (verify). Your federal return and Schedule EIC must be attached or the credit is denied.

The credit is applied after every other credit, it is nonrefundable, and it does not carry forward. That last sentence is the whole story for many families. The federal earned income credit is aimed at households with modest wages, and a household with modest wages has little Missouri tax after the standard deduction. A single parent with two children and $38,000 of wages has a federal credit of about $4,231 (verify) and a Missouri credit of $846, but Missouri tax of about $405, so $441 of the credit evaporates. At $25,000 of wages the Missouri tax is zero and the credit is worth nothing at all.

Missouri tax figured with the $24,150 head-of-household standard deduction, the $1,400 exemption and no federal tax deduction (the child tax credit leaves these households with no federal liability). The credit is fully used only where the family earns enough to owe more Missouri tax than the credit.

Children, child care and the exemption that is not there

Missouri has no dependent exemption; a child changes the Missouri return only through filing status. A single parent files as head of household and gets the $24,150 standard deduction and the $1,400 additional exemption on line 15, confirmed on the 2026 Form MO-1040ES; against the $16,100 single deduction, the two together are worth about $444 of Missouri tax. The qualifying widow(er) status gets the same $1,400. There is no Missouri child tax credit and no credit for child and dependent care. The federal child and dependent care credit reduces federal tax, which, through the federal tax deduction, slightly raises Missouri tax, as the child tax credit does.

The child care break that does reach Missouri is the one taken above the line: a dependent care flexible spending account through an employer excludes up to $7,500 of pay from wages before it reaches federal AGI, and Missouri never sees it. At 4.7% a full account saves about $352 of Missouri tax on top of the federal savings, which makes the account more valuable than the federal credit for most Missouri families who have the choice.

529 plans: MOST or anyone else’s

Contributions to a qualified 529 plan are subtracted on Form MO-A, Part 1, line 12, up to $8,000 per taxpayer and $16,000 on a married combined return, and the plan does not have to be Missouri’s. A family already holding an account in another state’s plan gets the same deduction as a MOST account holder. The deduction is per taxpayer, not per child, so a couple with three children still deducts $16,000, and grandparents who own the account take their own deduction on their own return. A nonqualified withdrawal that earned a deduction going in is added back on MO-A line 3. Qualified withdrawals, which under federal law include K-12 tuition up to the federal limit and student loan repayments, are not added back. Missouri has no K-12 tuition credit or deduction of its own, so routing private school tuition through a 529 is the only state break for it. The Department also offers to direct-deposit a refund into a MOST account on Form 5632.

College

The federal education credits, the American opportunity and lifetime learning credits, reduce federal tax and do not reach the Missouri return; Missouri has no credit of its own for tuition. The student loan interest deduction is above the line and flows through. A student’s scholarship that is taxable federally is Missouri income too. A child with a summer job files a Missouri return only if income exceeds $1,200, and takes the dependent’s standard deduction from the federal return.

Giving to children’s charities: the 70% credit

The Champion for Children credit returns 70% of a contribution to a qualified child advocacy center, crisis care center or court-appointed special advocate program, up from 50% starting with 2025 gifts. The credit is claimed on Form MO-TC with a certificate from the agency, the statewide pool is capped, and the Department’s page lists a $50,000 per-taxpayer limit alongside a $2.5 million annual cap (verify). A $1,000 gift costs $300 after the Missouri credit and still earns a federal deduction if you itemize. Related credits exist for gifts to diaper banks, maternity homes and pregnancy resource centers and food pantries, each with its own percentage and cap. These are the only places where Missouri’s tax code is generous to a family, and they reward the family that gives rather than the family that needs.

Two-earner couples and the combined return

A married couple who filed a joint federal return files a Missouri combined return, but Missouri figures each spouse’s income separately and runs each share down the rate chart. Since the brackets below 4.7% are worth about $180 per person, a couple where both work saves roughly $180 by the split compared with taxing the total as one. Software handles the allocation; the thing to watch is that items belonging to one spouse, a capital gain or a 529 contribution, are entered for that spouse. A couple with a stay-at-home parent gets only one trip through the low brackets.

Tips, overtime and the second job

The federal deductions for tips and overtime that began with 2025 do not reach the Missouri return. A server with $12,000 of reported tips who owes no federal tax on them owes Missouri $564. A nurse with $9,000 of overtime premium pay owes Missouri $423 on it. The Department has said in writing that these deductions, along with the car-loan interest and senior deductions, apply only federally. Families counting on a larger refund from the new federal rules should expect the Missouri refund to look like last year’s.
