Don't lose speed and productivity during tax season. Make sure your Intuit ProConnect Lacerte software runs optimally and ensure compliance by checking your system against our system requirements below. Upgrading will keep you from experiencing unnecessary slowdowns, hassles, and a less-than-optimal experience. More importantly, it will allow for further productivity during the busy tax season.
