The use of faxing services to transmit employer tax transcripts, including the 94x series of forms, to third parties is to end June 28, the Internal Revenue Service said June 5.

Forms 940, 941, 943, 944, and 945, make up the series collectively known as Forms 94x.

Ending the tax transcript faxing service, which applies to tax professionals and individual taxpayers, is part of the agency’s ongoing fight against identity theft, the agency’s Small Business/Self-Employed Division said in an email.

The IRS also said it would stop third-party mailing of tax returns and transcripts July 1, including Form 4506, Request for Copy of Tax Return. The form is to be amended to remove the option for mailing to a third-party, the agency said in a news release (IR-2019-101).

Registered account holders of electronic services can continue to access a variety of business transcripts by using the Transcript Delivery System or by asking the IRS to send a transcript to their e-services secure mailbox, which also is know as a Secure Object Repository.

In a separate notice (IR-2019-104) issued June 5, the IRS again warned of ongoing phishing emails and telephone scams, even though the April filing deadline has passes. The agency said two new variations of scams have appeared since mid-April.

In one, scammers mention overdue taxes and threaten the cancellation of an individual’s Social Security number if the taxes are not paid. In the other, a bogus tax agency sends a letter threatening an IRS lien or levy.

The agency said common signs of a scam include calls demanding immediate payment using a credit card, threatening law enforcement actions, and demanding payment without giving the taxpayer an opportunity to question or appeal the taxes owed, the IRS said.

The IRS reminded taxpayers that the agency does not leave recorded, urgent, or threatening messages. The agency also does not initiate contact with taxpayers via email to request personal or financial information.
