The official application, called IRS2Go, allows users to check the status of their refunds, make payments and access free tax preparation services from a compatible smartphone.
Mobile users are also tied into a host of other resources, like instructional videos and tax tips through the agency’s social media pages and direct contact functions.
Refund status is reportedly available to taxpayers as soon as 24 hours after filing electronically and roughly four weeks after filing a return by mail.
The mobile initiative is another digital step for the agency that first allowed a mere 25,000 electronic filings, or e-filings, to pilot in 1986.
In the 30 years since, more than 91 percent, or 129 million tax returns, have been filed online in 2015, according to efile.com.
The app, which was originally announced in January 2011, is available through the Apple App Store, Google Play and Amazon.
