What is the Third Stimulus Check?

American Rescue Plan Act Overview
Payment Amounts and Eligibility
Key Differences from Previous Stimulus Payments

The third stimulus check, officially known as the third Economic Impact Payment, was authorized under the American Rescue Plan Act of 2021, signed into law on March 11, 2021. This payment represented the largest direct stimulus payment to date, providing up to $1,400 per eligible individual, including dependents of all ages. Unlike the first two stimulus payments, which had age restrictions for dependents, the third payment expanded eligibility to include adult dependents, college students, and elderly relatives.

Payment Structure and Maximum Amounts

The third stimulus check provided a maximum payment of $1,400 per eligible individual, which was significantly higher than the previous payments of $1,200 and $600. For married couples filing jointly, the maximum payment was $2,800, and families could receive additional payments for each qualifying dependent. This expansion to include all dependents, regardless of age, made the third stimulus check particularly valuable for families with older children, college students, or elderly dependents.

Eligibility Criteria and Income Thresholds

Eligibility for the third stimulus check was based on adjusted gross income (AGI) from the most recent tax return on file with the IRS. The income thresholds were: $75,000 for single filers, $112,500 for head of household, and $150,000 for married couples filing jointly. Unlike previous stimulus payments, the phase-out was more gradual, allowing more middle-income families to receive partial payments. The payment completely phased out at $80,000 for single filers, $120,000 for head of household, and $160,000 for married couples.

Dependent Eligibility Expansion

One of the most significant changes in the third stimulus check was the expansion of dependent eligibility. While the first two payments only included children under 17, the third payment included all qualifying dependents regardless of age. This meant that families with college students, elderly parents, or other adult dependents could receive additional $1,400 payments for each qualifying dependent, significantly increasing the total household payment amount.

Key Payment Amounts:

Individual payment: Up to $1,400 per eligible person
Married couple: Up to $2,800 for joint filers
Dependents: $1,400 for each qualifying dependent of any age
Family of four: Up to $5,600 total payment

Step-by-Step Guide to Using the Stimulus Calculator

Gathering Required Information
Input Methodology
Understanding Your Results

Accurately calculating your third stimulus check requires gathering the correct information and understanding how the IRS determines eligibility and payment amounts. Follow this comprehensive methodology to ensure you get the most accurate estimate of your stimulus payment.

1. Determine Your Adjusted Gross Income (AGI)

Your AGI is the key factor in determining stimulus check eligibility and amount. Find this number on line 11 of your 2020 Form 1040 (or line 8b of your 2019 Form 1040 if you haven't filed 2020 taxes yet). AGI includes all income sources (wages, self-employment, interest, dividends, etc.) minus certain deductions like IRA contributions, student loan interest, and alimony payments. If you haven't filed your 2020 taxes, the IRS will use your 2019 AGI for the initial calculation.

2. Identify Your Filing Status

Your filing status determines the income thresholds for receiving the full stimulus payment. Single filers have a $75,000 threshold, head of household filers have a $112,500 threshold, and married couples filing jointly have a $150,000 threshold. Your filing status should match what you used on your most recent tax return. If you're unsure, check your previous year's tax return or consult with a tax professional.

3. Count Your Qualifying Dependents

Unlike previous stimulus payments, the third check included all qualifying dependents regardless of age. This includes children, stepchildren, foster children, siblings, parents, and other qualifying relatives who meet the dependency tests. Each qualifying dependent adds $1,400 to your total payment. Make sure to count all dependents who would be eligible based on your most recent tax return.

4. Understand Phase-out Calculations

If your AGI exceeds the threshold for your filing status, your payment will be reduced by 5% of the amount over the threshold. For example, a single filer with $80,000 AGI would have their payment reduced by $250 (5% of $5,000). The payment completely phases out when AGI reaches $80,000 for single filers, $120,000 for head of household, and $160,000 for married couples filing jointly.

Income Thresholds by Filing Status:

Single: Full payment up to $75,000 AGI, phases out by $80,000
Head of Household: Full payment up to $112,500 AGI, phases out by $120,000
Married Filing Jointly: Full payment up to $150,000 AGI, phases out by $160,000

Common Misconceptions and Important Considerations

Eligibility Myths
Payment Timing and Delivery
Tax Implications

Several misconceptions surround the third stimulus check, and understanding these can help you avoid confusion and ensure you receive the correct payment amount.

Myth: Stimulus Payments Are Taxable Income

This is false. Stimulus payments are not considered taxable income and do not need to be reported on your tax return. They are advance payments of a tax credit, which means they don't increase your tax liability. However, if you didn't receive a payment you were eligible for, you can claim it as a Recovery Rebate Credit on your tax return.

Payment Timing and Delivery Methods

The IRS began issuing third stimulus payments in March 2021, with most payments delivered via direct deposit, paper check, or prepaid debit card. The delivery method was based on how you received your previous stimulus payments or tax refunds. If you didn't receive a payment you were eligible for, you could claim it as a Recovery Rebate Credit on your 2021 tax return.

Dependent Age Restrictions

Unlike the first two stimulus payments, the third payment included all qualifying dependents regardless of age. This was a significant change that benefited families with college students, elderly parents, or other adult dependents. Each qualifying dependent added $1,400 to the total household payment, regardless of their age.

Important Facts:

Stimulus payments are not taxable and don't need to be repaid
All qualifying dependents are eligible, regardless of age
Payments are based on the most recent tax return on file
You can claim missing payments as a Recovery Rebate Credit

Mathematical Derivation and Calculation Examples

Phase-out Formula
Dependent Calculations
Real Calculation Scenarios

The third stimulus check calculation involves specific mathematical formulas for determining eligibility and payment amounts, particularly for households with income above the threshold levels.

Base Payment Calculation

The base payment is $1,400 per eligible individual. For a family, this includes the taxpayer(s) and all qualifying dependents. The total base payment is calculated as: Base Payment = $1,400 × (Number of eligible individuals + Number of qualifying dependents). For example, a married couple with two children would have a base payment of $5,600 ($1,400 × 4).

Phase-out Reduction Formula

For income above the threshold, the payment is reduced by 5% of the amount over the threshold. The formula is: Reduction = (AGI - Threshold) × 0.05. For example, a single filer with $80,000 AGI would have a reduction of $250 (($80,000 - $75,000) × 0.05). The final payment would be $1,150 ($1,400 - $250).

Complete Phase-out Points

The payment completely phases out when the reduction equals the full payment amount. For single filers, this occurs at $80,000 AGI ($75,000 + ($1,400 ÷ 0.05)). For head of household, it's $120,000 ($112,500 + ($1,400 ÷ 0.05)). For married couples filing jointly, it's $160,000 ($150,000 + ($2,800 ÷ 0.05)).

Dependent Eligibility Rules

Qualifying dependents must meet the dependency tests from the tax code, including relationship, residency, and support tests. Unlike previous stimulus payments, there was no age restriction for dependents in the third payment. This meant that college students, elderly parents, and other adult dependents could qualify for the $1,400 payment.

Calculation Examples:

Single person, $70,000 AGI: Full $1,400 payment (under $75,000 threshold)
Married couple, $160,000 AGI: $0 payment (above $160,000 phase-out)
Head of household, $115,000 AGI: $1,050 payment ($1,400 - $125 reduction)
Family of four, $140,000 AGI: $4,200 payment ($5,600 - $1,400 reduction)
