Tax refunds and treatment-related deductions

Tax credits and medical deductions can change your tax bill after a year of treatment.

What it is

Tax credits and medical deductions can change your tax bill after a year of treatment.

A change in earnings can move federal tax credits up or down. Unreimbursed treatment costs can qualify for a federal medical deduction when you itemize. South Carolina changed its deduction rules for tax year 2026, so the state return needs a separate check.

Rules
  • For tax year 2026, a full-year South Carolina resident’s state earned-income credit is 125% of the allowed federal EITC, capped at $200, and can reduce state income tax owed but does not pay out any unused credit. South Carolina’s separate income-adjusted deduction starts at $15,000 for single or married-filing-separately, $22,500 for head of household and $30,000 for joint or qualifying surviving-spouse returns, with income phaseouts. Federal medical itemizing does not automatically carry over. Your social worker can help find a preparer to check the actual return; the ordinary filing deadline is April 15, 2027. The state deduction phaseout runs from federal adjusted gross income of $40,000 to $95,000 for single or married-filing-separately returns, $60,000 to $142,500 for head-of-household returns, and $80,000 to $190,000 for joint or qualifying surviving-spouse returns. The preparer uses the statutory formula and rounding.
  • Only unreimbursed medical expenses above 7.5% of adjusted gross income are deductible, and only if you itemize. Mileage to treatment counts at the IRS medical rate (20.5 cents a mile through June 2026, 23.5 from July).
  • Refundable credits are paid only on a filed return, including when no tax is owed.
What you get
  • Federal credits, part of them refundable, paid on a filed return.
  • A review of the South Carolina return under the rules for your treatment year.
  • A possible medical-expense deduction when qualifying unreimbursed costs are high enough to itemize.
What to keep
  • Bills, insurance statements, parking receipts, mileage records and lodging records can help a preparer review treatment expenses.
If you decide to apply
  1. Your social worker can help a tax adviser identify which treatment receipts and mileage records may matter for your return.
  2. Ask a preparer how South Carolina’s 2026 deduction changes affect your return.
  3. Ask a free tax-help service (VITA) or a qualified preparer to review credits and the medical deduction at filing time.

Missed years
  • Earlier tax years can still be claimed; each has its own deadline.
Good to know

A credit, a refundable amount and a deduction are three different things; a preparer should check them before anyone promises a refund. Today’s benefit-screening income is not the tax-year figure.

Other details
  • Federal credits and deductions change by tax year; confirm the year’s figures when you file.
Official sources
Ask your social worker

“Is there free tax help you recommend, and should we be keeping treatment receipts and mileage for a medical deduction?”

Why I’m asking: We want to claim any refund we are due in a year with different income and high bills.

Who does what

The three parts, side by side. The agency decides; nobody on this page does.

You

Keep the mileage log, parking and lodging receipts and every medical bill; file even in a year you owe nothing.

Your social worker

Points you to a free VITA tax site and, if a parent is paid by Medicaid for home care, to the paperwork that marks that pay as excludable.

The care team

Records and letters when the application asks for them.

Who decides
The IRS, on the return you file
Ask your social worker
“Is there a free tax help site for families here? If a parent is paid through Medicaid for our child's home care, what paperwork marks that pay as excludable?”

How to apply

First step: Start a mileage and lodging log now, keep every medical bill, and ask the social worker for the free VITA tax site near you.

  1. Start a mileage and lodging log the week of diagnosis.
  2. Ask HR about the dependent-care account when a sibling needs paid care so a parent can work.
  3. File even in a year with no tax owed; the child tax credit and earned income credit can still pay.

Where it starts: Federal tax return; free VITA tax sites for lower-income families

What to gather

  • A mileage log with dates and destinations
  • Parking, toll and lodging receipts
  • Every medical bill and the insurance statements showing what you paid
  • The employer's dependent-care account form, if offered

How long: Settled on the tax return for the year. A refund follows filing.

What a yes looks like

A smaller tax bill or a refund that reflects the deduction and the credits.

What a no looks like, and the next move

The standard deduction beats itemizing: the mileage and lodging are then unused, but the child tax credit and earned income credit still apply.

Watch out

  • Throwing away the mileage log. Hospital trips at 20.5 cents a mile (January to June 2026) and 23.5 cents (July to December), plus parking and tolls, add up over a treatment year.
  • The lodging cap is $50 a night per person, meals not included, and only for stays needed for care at a hospital.
  • The $7,500 dependent-care account is for care that lets the parents work, such as a sibling's daycare. It is set up through an employer, usually at open enrollment or after a family change.
  • Not every Medicaid-paid wage is excludable. The exclusion is for care of someone living in the provider's home under a Medicaid program; ask the program for its form.
  • Retirement money is a last resort with tax costs. A medical hardship withdrawal does not itself waive the early-withdrawal penalty. The medical-expense penalty exception covers only qualifying expenses above 7.5% of adjusted gross income; ordinary income tax still applies to untaxed money.
  • The emergency personal-expense withdrawal exception has separate balance, annual and repeat-use limits. Ask the plan administrator or tax preparer before using it; penalty relief is not an exemption from ordinary income tax.

The numbers and the rules

The arcane layer, kept on purpose. Checked September 10, 2026.

What it is worth

Medical costs above 7.5% of income deductible if you itemize; mileage 20.5 cents (January–June 2026) and 23.5 cents (July–December); lodging $50 a night per person; dependent-care account $7,500; child tax credit up to $2,200 a child.

  • $7.5 (only the part above this counts, and only if you itemize) — Medical-expense deduction floor
  • $20.5 — Medical mileage, January to June 2026
  • $23.5 — Medical mileage, July to December 2026
  • $50 (an accompanying parent counts; meals do not) — Lodging away from home for care, per person per night
  • $7,500/year — Dependent-care account (FSA) limit, 2026
  • $3,750/year — Dependent-care account limit, married filing separately, 2026
  • $2,200/year (maximum; not a guaranteed refund) — Child tax credit per qualifying child, 2026

Legal protection: Pay from Medicaid to a parent who provides the child's home care in the same home can be left out of federal income (IRS Notice 2014-7, since January 3, 2014) · That excluded pay can still be counted as earned income for the earned income credit, all of it or none · Parking and tolls count on top of the mileage rate

What it costs the family: None. A free VITA tax site or a preparer can run the numbers.

Decisions this site cannot make: The tax return

Expect friction on: Receipts and a mileage log · Itemizing versus the standard deduction

The trap: Throwing away the mileage log. The rate is 20.5 cents a mile for January to June 2026 and 23.5 cents from July; parking and tolls are on top. The lodging cap is $50 a night per person, meals not included.

What changes by state: Nothing here is state law. Some states add their own credits; a tax preparer or a free VITA site can check.
