The Treasury Department said on Friday that stimulus payments would begin arriving in bank accounts by direct deposit this weekend as the Biden administration tries to get much-needed money to struggling families.

Treasury and Internal Revenue Service Officials said the payments would be released in batches over the next several weeks, with some coming in the mail in the form of checks or debit cards. The payments are the first big logistical test for Treasury Secretary Janet L. Yellen, as millions of Americans are anxiously awaiting the economic aid.

The payments will provide up to $1,400 per individual, including dependents. The amounts will be reduced for people making more than $75,000 and for married couples who earn more than $150,000. Individuals earning more than $80,000 or couples making more than $160,000 will not get payments.
