Inputs

Federal Individual Income & Filing inputs

Choose the tax year for the credit amount and phaseout assumptions you enter.

Range: 0–20 count

Enter the credit amount that applies to one qualifying dependent for the selected tax year and scenario.

Range: 0–100,000,000 $

Enter the income measure used by the rule you are modeling, using the same tax year and filing assumptions.

How to interpret this result
Potential credit is the dependent count multiplied by the supplied credit amount. The usable credit is capped by the supplied current federal tax liability; refundable rules and eligibility are outside this estimate.
Applicability and limits
Confirm dependent qualification, credit type, filing status, income definition, phaseout threshold, refundability, and tax-year limits against current IRS instructions or the applicable state rule. This tool does not determine eligibility.
Calculation basis
Only the named inputs and formula relationships are used. The selected tax year is context for the assumptions you enter; no credit amount, threshold, or rate is silently looked up.

What to check

  • A taxpayer enters the amounts from a current planning worksheet to estimate a federal result before filing or changing a tax decision.
  • Use it when preparing, reviewing, or comparing a federal tax estimate.
  • Confirm dependent qualification, credit type, filing status, income definition, phaseout threshold, refundability, and tax-year limits against current IRS instructions or the applicable state rule. This tool does not determine eligibility.
