Treasury will begin sending the $600 stimulus checks.

While Congress continues to spar over whether to increase the size of stimulus payments to $2,000, the Treasury Department on Tuesday said it would begin depositing $600 checks into Americans’ bank accounts as early as Tuesday evening.

Treasury Secretary Steven Mnuchin, in a tweet, said that the government had begun the process of getting money to individuals through direct deposit payments, while paper checks would start to be mailed on Wednesday.

The $600 checks are part of the $900 billion stimulus bill that President Trump signed into law on Sunday.

The money is expected to flow faster than the initial round of $1,200 checks that lawmakers approved in March because the Internal Revenue Service and Treasury already have the necessary information — including who qualifies for a payment and how they want their money delivered.

Individual adults with an adjusted gross income of up to $75,000 a year on their 2019 tax returns will receive a $600 payment. A couple (or someone whose spouse died in 2020) earning up to $150,000 a year will get twice that amount. There is also a $600 payment for each child for families who meet those income requirements.
