Important note: The step-by-step instructions and videos below are slightly out of date due to an upgrade to Denver’s eBiz Tax Center on January 6, 2016.You will find the majority of the instructions below to still be accurate; however, some of the navigation is different. There is no longer a left sidebar – instead you will now find the links you need in the navigation bar at the top of the window or in the "I Want To…” action box in the right corner just below the navigation bar.
Updated how-to instructions are coming soon.
