The checks are part of a $1.9 trillion economic relief package called the American Rescue Plan.
For example, a married couple with an adjusted gross income of up to $150,000 and two kids will get a $5,600 stimulus check.
The income limits to get a full check are $75,000 for single filers and $150,000 for married joint filers.
Eligibility for the third stimulus check is based on your AGI on your last tax return. AGI is calculated by subtracting deductions (like retirement account contributions) from income.
