If you've ever wonder if a better method to stay on top of withholding tax changes existed, wonder no longer. With the Tax Notification Service, you'll be up to date with recent payroll withholding and tax changes and connected directly to the supporting documentation. 

Once logged in, all tax changes for the current year are presented in alphabetical order by state. You can look for specific tax changes over time by selecting any of the tax categories, or by clicking the name of the state you are researching. You can also view tax changes by year and Symmetry Tax Engine release number. Documentation from the state regarding each change is included, when available, as well. That means no more excess time spent plowing through pages of rates on federal and state websites.
