Sales tax in OfficePro is built from three pieces. Set them up in this order and the rest follows.
Everything below lives on the Admin page, under Sales Tax Setup Information.
Add one row per authority. Do not add a single combined row for "sales tax" at the total rate - you will not be able to break the figure down by authority when you file, which is the reason for keeping them apart.

The Group Rate column shows the combined figure. Two things to know about it:
A group with no jurisdictions is a real, useful setting, not an unfinished one. It means "no tax here", and it is how you handle orders shipped somewhere you have no obligation to collect. Most practices want exactly one of these.
Under Ship-To Regions, click Add Ship-To Region and pair a Destination with the tax group it should use. The Everywhere else row is the catch-all for any destination you have not named - point it at your no-tax group unless you genuinely collect tax nationwide.
When an order is placed, the destination decides the group, the group decides the rate, and the rate is worked out and saved onto that line.
This is the question every administrator asks first, so to be plain: editing a rate does not change what past orders charged. Each line stores the rate applied when it was created. Put the new rate in on the day it takes effect and past sales, refunds against them and your filed returns all keep the figures they had.
The one thing to be careful of is the reverse: because only one rate is held per jurisdiction, a report that recalculates tax from today's configuration rather than reading what each line stored will misstate a closed period. Read the sales tax report, which uses the stored figures.
Rates and rules are set by your tax authority and change without telling you. OfficePro charges what you configure; confirming what to configure is your accountant's job, not the software's.
