"We will create a web-based system for people where [if] we don't have their direct deposit [information], they can upload it, so that they can get the money immediately, as opposed to checks in the mail," Mnuchin said on CBS News's "Face the Nation."

For individuals making less than $75,000 and married couples making less than $150,000, the checks amount to $1,200 per adult and $500 per child. The rebate amounts phase out above those income levels.

Mnuchin has said that he expects taxpayers who have provided direct deposit information to the IRS to receive their checks "within three weeks." The law allows the IRS to disburse payments electronically to bank accounts that taxpayers had authorized in 2018 or later for tax refunds or other federal payments.

People who don't provide direct deposit information to the IRS are expected to receive their rebates more slowly because their payments will have to be sent in the mail. A GOP aide to the Senate Finance Committee told reporters last week the the Bureau of Fiscal Service is limited in how many physical checks it can issue at a time.
