The IRS provides some tips for people that filed their taxes and are wondering where their refund is. Your refund status is available to check with the IRS within 24 hours of submitting your e-filed return or 4 weeks after mailing in a paper return. The IRS does not recommend calling them but rather using this website to check on the status. You will need your social security number, filing status, and refund amount in order to check the status of your refund. The status of your refund only updates once a day so there’s no reason to check it more than once.
