If you're getting a direct deposit, the tool will show the date of the deposit and the last four digits of the bank account number. Or you might see the date a check or debit card was mailed to you (these may take up to three to four weeks to arrive, the IRS notes). Alternatively, you might see a "not available" message. What if I don't recognize the bank account number? Don't panic — it's most likely not fraud. It actually has something to do with how you filed your 2019 taxes and received your refund. Millions of people file their taxes through online tax software providers every year. It can be simple, convenient, and more affordable than visiting a CPA (for many taxpayers, it's free).
