Formula Used
Base amount = ($600 × eligible adults) + ($600 × qualifying children)
Phaseout reduction = max(0, adjusted gross income − filing threshold) × 5%
Estimated payment = max(0, base amount − phaseout reduction)
Recovery rebate gap = max(0, estimated payment − amount already received)
Thresholds used are $75,000 for single or married separate, $112,500 for head of household, and $150,000 for married joint returns.

Second Stimulus Check Overview
The second stimulus payment was created to support eligible households during the pandemic. It was smaller than the first payment, but the rules still needed careful checking. This calculator helps users estimate the possible payment using filing status, adjusted gross income, and qualifying children.
Eligibility Basics
The standard adult amount was $600 for each eligible adult. A married joint return could include two eligible adults. Each qualifying child under age seventeen could add another $600. Adult dependents did not add an amount for this payment. A valid Social Security number was also important for eligibility.
Income Phaseout
The payment started to reduce when income passed the allowed threshold. Single and married separate filers used $75,000. Head of household filers used $112,500. Married joint filers used $150,000. The reduction equaled five percent of income above the threshold. A larger household could still receive a payment at higher income, because child amounts increased the starting credit.
Why This Tool Helps
Manual estimates can be confusing when several rules apply together. The calculator separates base amount, income threshold, phaseout reduction, and final estimate. It also compares any amount already received. That helps show a possible recovery rebate difference, when the calculated credit is higher than the received payment.
Important Limits
This tool is for planning and education. It does not replace official tax advice. IRS rules may depend on return details, identity rules, offsets, and other filing facts. Use your final tax return records when checking any credit. Keep notices, payment records, and transcript details for support.
Practical Use
Start with the filing status used on the relevant return. Enter adjusted gross income from the return. Add only qualifying children who met the age and number rules. Then enter any payment already received. The result shows the estimated payment before and after phaseout. It also shows the remaining gap, when applicable. Use the export buttons to save the calculation for your records.
Record Keeping Tips
Save each estimate with the filing inputs used. This makes later review easier. If numbers change, run a fresh calculation. Compare the saved result with bank records, IRS notices, and return worksheets before making decisions about any claim or adjustment later.
FAQs
What was the second stimulus check amount?
The basic amount was $600 per eligible adult. A qualifying child under age seventeen could add another $600. Income phaseout rules could reduce or remove the payment.
Which income amount should I enter?
Enter adjusted gross income from the tax return used for the payment or recovery rebate review. AGI is usually found on the main federal return.
Do adult dependents add money?
No. For this payment, adult dependents did not add a $600 dependent amount. The child amount generally applied to qualifying children under age seventeen.
How does the phaseout work?
The calculator reduces the base amount by five percent of income above the filing threshold. The result cannot go below zero.
What if I already received a payment?
Enter the amount already received. The calculator compares that amount with the estimate and shows a possible remaining recovery rebate gap.
Does filing status matter?
Yes. Filing status controls the income threshold. Joint filers used $150,000, heads of household used $112,500, and single or separate filers used $75,000.
Why is my estimate zero?
Your income may be above the cutoff, or the SSN settings may remove eligibility. A zero base amount also creates a zero estimate.
Is this official tax advice?
No. This calculator is for education and planning. Always compare results with tax records, IRS notices, and professional guidance when needed.
