Income information forms generally are required to be provided/sent to the recipients by January 31st. If January 31st falls on a weekend, the deadline is extended to the next business day. The deadline for 2008 information forms is February 2, 2009 (February 1, 2010 for 2009 returns). These information forms include Form W-2 (Wage and Tax Statement) as well as the 1099 series, etc.
The only requirement is that at least 90% of your tax liability must be paid by the original deadline (April 15) to avoid late fees. You can mail your state tax payment using Colorado Form DR 0158-I (Payment Voucher for Automatic Colorado Extension for Individuals). Note that you are not required to file Form DR 0158-I if you electronically pay your state tax liability online.
