Officials say social security beneficiaries with children should act immediately to ensure they get their full stimulus payment. 

The Social Security Administration released a notice Monday saying that anyone who didn't file their taxes for 2018 or 2019 and has dependents younger than 17 should not wait for the automatic deposit of their $1,200 stimulus payment.

Anyone who meets that criteria is urged to go to the IRS webpage and fill out the online form to make sure they receive the additional $500 payment per child. The SSA warns that anyone who doesn't take this action may only receive the base $1,200 payment.
