The U.S. Internal Revenue Service (IRS) has a problem. The federal agency today announced that a hardware failure has brought down some of its systems, including the Where’s My Refund? feature.

“Taxpayers can continue to send their tax returns to their e-file provider; these companies will hold the tax returns until the IRS resumes accepting electronic tax returns,” the IRS said in a statement on the news.

Returns for the 2015 tax year are due on April 18 this year.

The IRS says it still thinks nine out of every 10 taxpayers who are owed refunds will receive them within three weeks of submitting their returns.
