If you are signed up for the Annual Tax Subscription you will have access to download Tax Rates to auto update your Zip Code Tax Rates as shown below:
Go to Tools > Import > Import Sales Tax Rates
Check the states you would like to update and click "Show Data". The bottom-half of the window will display all the zip codes and their tax rates for the selected states.
When the grid has finished loading, click "Update Tax Rates" to import all the new rates. The window will begin loading and display some statuses in the middle. When you are prompted with the message "Import Complete", you can close the window!
