Aug. 1, 2024 If you get an unexpected letter, email or text that claims to be from the IRS or another trusted source – like a bank, credit company or tax software provider – here are some tell-tale signs that it’s a scam: Spelling errors or incorrect grammar. A link or attachment with a slightly misspelled URL or an unusual one, such as irs.com. All trusted IRS links go to irs.gov. A threatening or urgent request to pay now, follow a link or open an attachment. If you receive a request from the IRS in the mail or by phone, log in to your IRS Online Account to find a copy of the notice or letter, or contact IRS customer service to authenticate it.
