Incorrect locations can lead to wrong tax rates; select the exact base location.

3. Ensure Proper Tax Classes Setup

Visit WooCommerce > Settings > Tax > Tax Classes for defining tax classes.
Make sure each product is assigned the correct tax class.

4. Update Tax Rates Manually

Go to WooCommerce > Settings > Tax > Standard Rates to add or update tax rates.
Check for any outdated or missing tax rates in your standard rates list

5. Use Geolocation for Customer Address

Enable Geolocate Address under WooCommerce > Settings > General.

If using a caching plugin, clear your website cache to prevent old tax data from being used.

Also clear browser and WooCommerce-specific caches.

Go to WooCommerce > Settings > Tax and enable debug mode.

This helps trace tax calculation errors, offering insights into potential misconfigurations.

8. Test Tax Calculation with Different Addresses

Add products to the cart and check tax calculations with different customer locations.

This will help identify if errors are location-specific.

9. Update WooCommerce and Plugins

Ensure WooCommerce, theme, and plugins are up-to-date for proper functionality. Tax issues may be caused due to outdated or incompatible versions.

10. Disable Conflicting Plugins

Temporarily disable plugins that may interfere with WooCommerce’s tax system. Test tax calculations after disabling; re-enable plugins if no issues arise.

11. Reconfigure Tax Display Options

Set tax display options under WooCommerce > Settings > Tax.
Choose whether to display prices inclusive or exclusive of tax for consistency.

12. Apply Accurate Rounding Settings

Rounding errors can affect final tax calculations; enable rounding under WooCommerce > Settings > Tax.
Rounding adjustments apply to subtotal levels or per-line items.

13. Contact WooCommerce Developer

Reach out to a WooCommerce developer in Singapore if issues persist.
