ACI Worldwide and PayNearMe have partnered to enable consumers to pay their federal taxes in cash at some 7,000 7-Eleven stores via a barcode sent to their smartphone and scanned at the register, according to a press release.

To obtain a PayNearMe barcode, taxpayers visit www.officialpayments.com/fed, choose their IRS form type, and select "Pay with Cash" as their payment option. They can elect to receive their barcode via email to print, or have it sent to their smartphone, which presents them with a list of nearby 7-Eleven stores where they can pay, according to the announcement.

Once the payment is made, the taxpayer receives a receipt as proof of transaction. Payments are typically posted within two business days, however users are advised to initiate payment at least seven business days prior to the tax payment deadline due to IRS identity verification requirements. 

A taxpayer's federal payment in cash cannot exceed $1,000 per day or two payments per tax period. A service fee of $3.99 is charged for each payment.

"Our bill payment solution is quick, easy, reliable and secure, which is why OfficialPayments.com is the longest tenured bill payment site for the IRS, having processed $14 billion in IRS tax payments since 1999," said Carolyn Homberger, group president of ACI Worldwide. "Today's consumers want convenience, as evidenced by the more than 75 percent of IRS electronic payments that are made through OfficialPayments.com via online or a mobile browser. Adding a new cash payment option that is mobile accessible brings convenience and another flexible payment option, which is powered by PayNearMe."
