The tax deadline has been extended for Pennsylvania residents, after technical problems shut down the state government's website for three hours.
The Monday afternoon outage affected many of the departments under the governor's jurisdiction, including the Revenue Department on the last day to file taxes.
Pennsylvanians were unexpectedly unable to file taxes online for a few hours or get tax forms online or help from its online customer service center.
As a result, the department says it won't penalize income tax returns that are filed by Tuesday midnight, a day late.
The outage began around 1:30 p.m. yesterday and was resolved at about 4 p.m. Officials couldn't say why it happened, just that it wasn't triggered by a cyber-attack.
