A very common reason QuickBooks sales tax is not working is incomplete or incorrect setup.

This includes:

1. Sales tax not enabled

2. Incorrect tax agencies assigned

4. Outdated QuickBooks Version or Tax Rates

Using outdated software can cause:

1. Missing tax updates

2. Incorrect tax calculations

3. Sales tax reports not refreshing

5. Switching Between Old and New Sales Tax Center

Migrating between legacy sales tax and Automated Sales Tax can cause:

1. Missing tax data

2. Broken tax links

3. Incorrect balances

6. Damaged Company File or Data Issues

Data damage may prevent QuickBooks from:

1. Applying tax correctly

2. Updating tax payable balances

3. Generating accurate reports
