Idaho School Choice Tax Credit for Multiple Children: Per-Child Caps and Family Strategy

Per-Child Caps, No Household Limit

The Idaho Parental Choice Tax Credit provides up to $5,000 per eligible student per tax year ($7,500 for students with qualifying disabilities). There is no statutory limit on the total number of students a single household can claim, as long as each child individually meets the eligibility criteria.

A family with three eligible children can claim up to $15,000. A family with five children can claim up to $25,000. The per-child structure means larger families benefit proportionally — and the credit is fully refundable, so the entire amount comes back as a refund if it exceeds your state tax liability.

Each Child Must Qualify Independently

Every child you include on the application must meet the same individual requirements:

• Idaho resident for the full tax year
• Age 5–18 at any time during the tax year (5–21 for students with qualifying disabilities)
• Not enrolled in an Idaho public school or public charter school during the semester claimed — even one course or extracurricular enrollment disqualifies that semester

The public school exclusion applies individually. If three of your four children are homeschooled and one attends public school, the three homeschooled children may qualify if they meet the other requirements. The fourth child is ineligible for a semester in which they were enrolled in public school, but can qualify for a later semester if they meet the requirements then.

How Multi-Child Families Hit the Cap

Reaching $5,000 per child in qualified expenses is easier for some families than others. For families with two or three children, the total spending adds up quickly:

Curriculum for three children (mixing publishers across subjects):

• Math (3 × $150): $450
• Language arts (3 × $180): $540
• Science (3 × $200): $600
• History/social studies (3 × $160): $480

Shared expenses distributed per child:

• Co-op academic fees for core instruction at an eligible provider (use each paid receipt amount)
• Achievement testing for three students: use the fee shown on each paid testing receipt

Per-child extras:

• Tutoring for one child (32 sessions × $50): $1,600
• Online course or instructional software for another child (only if it fits a statutory expense category; use the paid receipt amount)
• AP exam fees for oldest: use the fee shown on the paid registration receipt

Transportation (shared trips to an eligible instructional facility, with a contemporaneous mileage log)

These are illustrative expenses, not a fee schedule. Count only documented, qualified expenses; the combined statutory maximum for three standard students is $15,000.

The Advance Payment Complication

For families at or below 300% FPL, the advance payment option seems attractive — cash in hand within 60 days of approval rather than waiting for a tax refund. But the one-time-per-student career limit creates a strategic question for multi-child families.

Each child can receive an advance payment only once in their entire K–12 career. Once a child receives an advance, their future participation must go through the standard annual tax credit. And if a child first receives the standard credit, they become permanently ineligible for an advance.

For a family with a kindergartner and a high schooler, the calculus is different for each child. The high schooler has fewer remaining years — an advance now might make sense if cash flow is tight. The kindergartner has 13 years of eligibility ahead — saving the advance option for a year with higher expenses might preserve more flexibility.

Filing Mechanics for Multiple Children

On Form 40, you claim the total approved credit across all children on Line 42. The TAP application includes fields for each eligible student, with their individual expense amounts and documentation.

Keep expense records organized per child, not pooled. The Tax Commission evaluates student eligibility and expense caps per student. Separate records make each child's claim easier to substantiate; they do not guarantee that a review of one claim will have no effect on others in the household.

What "No Household Limit" Means Under the $50 Million Cap

The per-household freedom bumps into the statewide $50 million annual cap. A family claiming $25,000 for five children takes the same share of the cap as five single-child families each claiming $5,000. During years when application volume is high — 7,055 applications representing 12,561 students in the first cycle — multi-child families consume more cap capacity per application.

This doesn't change the individual eligibility rules. For 2025 and 2026, applicants above 300% FPL are waitlisted until the at-or-below-300% priority applications are satisfied. For 2027, prior-year credit recipients receive first priority, followed by applicants at or below 300% FPL. Remaining funds are allocated by submission timestamp, and each student has an individual cap within the statewide allocation.
