This is an acronym that relates to the Economic Stimulus Payment (EIP) of 2020.
Also known as the “stimulus check” of 2020, the EIP started being sent out by the IRS in mid-April. Qualified individuals received the payment mostly either via direct debit into their bank accounts or as a mailed check.
PSNA is an acronym for a frequent message the people encountered when using the Get My Payment (GMP) tool on the official IRS website. The tool was created in order to enable individuals to provide their direct-deposit information (routing number and bank account number), as well as a means to check the status of a payment to be delivered.
Many individuals, particularly early on, kept seeing the message “Payment Status Not Available” despite correctly entering their name, address, birthdate, and social security number.
It’s been surmised that this is due to the individuals’ data still not being loaded into the particular database that the GMP uses. The data are updated about once a day.
