DENVER (CBS4)– The Colorado Department of Revenue is extending the state income tax filing deadline by a day after the IRS had to do the same due to computer issues.

The IRS website for making payments and gaining access to other key services crashed during a flurry of last-minute filings on Tuesday.

While the IRS issues did not affect state filing, many people electronically file their federal and state tax returns at the same time. Third-party tax preparers said they would hold on to customer tax returns and file them after the IRS system was back online.
