Third Stimulus Check Calculator

Estimate your third stimulus payment under the American Rescue Plan based on your filing status, dependents, and income.

What This Calculator Does

This calculator estimates your third Economic Impact Payment under the American Rescue Plan Act of 2021. It uses your adjusted gross income, filing status, and number of qualifying dependents to determine whether you qualify for a full or partial payment.

The third stimulus check provided up to $1,400 per eligible individual and $1,400 per qualifying dependent. Unlike the first two rounds, dependents of all ages — including college students, older adults, and people with disabilities — qualified for the full amount.

How the Payment Is Calculated

The IRS calculated payments based on your most recent tax return at the time of processing. The calculator applies the same phaseout structure used by the IRS:

Full payment: Individuals earning up to $75,000 (or $150,000 for married couples filing jointly) received the full $1,400 per person plus $1,400 per dependent.
Phaseout range: Payments decreased gradually for incomes above those thresholds. The phaseout ended at $80,000 for single filers, $120,000 for heads of household, and $160,000 for married couples filing jointly.
No payment: Individuals earning above the phaseout cap received no payment.

The phaseout calculation is linear. For every dollar your income exceeds the threshold, your payment decreases by a fixed percentage until it reaches zero.

Dependents

Each qualifying dependent added $1,400 to the total payment. The IRS defined dependents as anyone you claimed on your tax return, including children under 19, full-time students under 24, and disabled adults of any age. Unlike previous stimulus rounds, there was no age cap.

How to Use the Calculator

Select your filing status (single, married filing jointly, or head of household).
Enter your adjusted gross income from your most recent tax return.
Enter the number of qualifying dependents you claimed.
Click calculate to see your estimated payment amount.

The result shows your estimated total payment, including amounts for yourself, your spouse (if filing jointly), and all qualifying dependents.

Understanding Your Results

The calculator provides an estimate based on the IRS phaseout formula. Your actual payment may differ if:

The IRS used a different tax year than expected.
Your income changed significantly between tax years.
You had adjustments or credits that affected your adjusted gross income.
You did not file a tax return for the relevant year.

The IRS automatically issued payments based on the most recent tax return on file. If you did not file a return, you may have needed to use the IRS Non-Filer tool to receive your payment.

Common Mistakes

Using the wrong income figure: The calculation uses adjusted gross income (AGI), not gross income or taxable income. Check your tax return for the correct AGI.
Misunderstanding dependent eligibility: All dependents qualified for the third stimulus, regardless of age. This was a change from the first two rounds.
Assuming the phaseout is the same for all statuses: The income thresholds and phaseout caps differ by filing status. Using the wrong status will produce an incorrect estimate.
Forgetting the spouse amount: Married couples filing jointly receive $1,400 for each spouse, plus $1,400 per dependent. The calculator accounts for this automatically.

Limitations

This calculator provides an estimate only. It does not account for:

Payments issued after the IRS processed an amended return.
Plus-up payments for people whose income dropped in 2020 compared to 2019.
Payments received as a Recovery Rebate Credit on a 2020 or 2021 tax return.
Offset of payments for certain debts (the IRS could reduce payments for past-due child support).

For the most accurate information about your actual payment, check your IRS online account or review IRS Notice 1444-C.

Practical Use Cases

Planning: Estimate your payment amount before filing your taxes to understand your expected Recovery Rebate Credit.
Verification: Confirm that the amount you received matches the IRS calculation based on your income and dependents.
Comparison: Compare your estimated payment under different filing scenarios if your marital status or dependent situation changed.
Budgeting: Understand whether you qualified for a full or partial payment to plan your finances accordingly.

FAQ

Did the third stimulus check include dependents of all ages?

Yes. Unlike the first two stimulus rounds, the third payment included $1,400 for every qualifying dependent regardless of age. This covered college students, elderly parents, and disabled adults claimed as dependents on a tax return.

What income does the calculator use?

The calculator uses adjusted gross income (AGI) from your most recent tax return. The IRS used the 2020 return if filed, or the 2019 return if the 2020 return had not been processed yet.

What if my income changed after the IRS issued the payment?

If your 2020 income was lower than 2019, you may have been eligible for a plus-up payment. If your 2020 income was higher, you did not need to repay the difference. The IRS based payments on the most recent return on file at the time of processing.

Can I still get the third stimulus if I didn't file a tax return?

Yes, if you were eligible. The IRS created a Non-Filer tool for people who did not file a return. Alternatively, you could claim the Recovery Rebate Credit on your 2020 or 2021 tax return to receive the payment.

What is the phaseout for married couples filing jointly?

Married couples filing jointly received the full payment if their AGI was $150,000 or less. The payment phased out completely at $160,000. The phaseout is linear, meaning the payment decreases gradually between those two amounts.
