In case you’re using Magento Commerce and you’re not in California or New York, you may want to disable Magento from charging taxes in those states. By default, Magento Commerce charges tax in California and New York.
To disable, go to Magento Admin>>Sales>>Tax>>Manage Tax Zones and Rates.
You’ll see two tax zones. One for CA and one for NY. Select the one you want to delete and click the delete button.
There you go.
