|---|---|---|---|---|---|---|---|
| One Child Basic | MFJ | $28,000 | 1 | $4,200 | $0 | $840 | $840 |

Formula Used
- Expense limit = $3,000 for one qualifying person, or $6,000 for two or more.
- Net care expenses = total work-related care expenses − excluded dependent care benefits.
- Earned income cap = taxpayer earned income for most statuses, or the lower earned income of both spouses for joint returns.
- Allowable expense base = smallest of expense limit, net care expenses, and earned income cap.
- Credit percentage = 35% for lower AGI, reduced by 1% for each $2,000, or part, above $15,000 until reaching 20%.
- Final usable credit = smaller of tentative credit and tax liability before this credit.

Frequently Asked Questions
1) What does this calculator estimate?
It estimates the U.S. federal child and dependent care credit using general rules for expense caps, AGI-based percentage, earned income limits, excluded benefits, and tax liability.
2) Does this calculator file my tax return?
No. It provides an estimate only. You still need to complete the correct tax forms and confirm eligibility details, provider information, and filing status requirements.
3) Why can the final credit be lower than the tentative credit?
The credit is generally nonrefundable, so the usable amount cannot exceed the tax liability entered before applying this specific credit.
4) Why are my expenses reduced by dependent care benefits?
Employer-provided dependent care benefits can already provide a tax benefit. Because of that, the calculator reduces expenses available for the separate credit estimate.
5) How does filing status affect the result?
Separate returns are usually not eligible unless a special exception applies. Joint filers generally use the lower earned income of both spouses as a limit.
6) What are student or disabled months used for?
They estimate deemed earned income in special situations. This helps when a taxpayer or spouse was a full-time student or unable to care for themselves.
7) Why does AGI change the credit percentage?
The credit percentage generally falls as AGI rises. Lower AGI can produce a higher percentage, while higher AGI usually reaches the minimum rate.
8) Can I use this for state childcare credits?
Not directly. Many states use different rules, percentages, income thresholds, or refundability rules, so separate state-specific calculations may be required.
