How this estimate works
It uses the IRS's 2026 numbers for a Head of Household filer, which is the status most single moms qualify for if a child lives with them more than half the year and they pay more than half the household costs.
- Standard deduction: $24,150. Income above that is taxed starting at 10%.
- Earned Income Tax Credit: up to $4,427 with one child, $7,316 with two and $8,231 with three or more. It phases in as you earn, then phases out above $23,890.
- Child Tax Credit: $2,200 per child under 17. It first wipes out tax you owe; up to $1,700 per child of what's left can come back as a refund, limited to 15% of your earnings above $2,500.
- Other dependents: $500 each, which only reduces tax you owe.
The IRS uses tables with $50 income bands, so your real numbers can differ by a few dollars. It doesn't include the child and dependent care credit, education credits or the new deductions for tips and overtime, which could raise your refund.
