Hi Kylerleu29,  

Thanks for joining this thread. Applying taxes to transactions in your QuickBooks self-employed account is essential to keeping your books balanced. I'd be happy to help.

This type of issue can be caused by browser cache and cookies as they can prevent the system from functioning effectively. I encourage you to refer to the following steps to complete some browser troubleshooting.
 

• Clear browser cache.
• Try in a private browser window.
• Use another browser type.
• Make sure you're using supported browsers.
• Turn off any ad and popup blockers temporarily.

If you're using a mobile app, I recommand that you refresh the app to ensure it's up to date. You can refer to the following steps to refresh the app.

For iOS

1. Go to Menu ☰ and tap Help & Feedback and then Refresh Data
2. Tap Refresh to confirm.

For Android

1. Tap More Options from the Menu ☰
2. Select Settings and then Refresh Data
3. Click YES to confirm.

In addition, I encourage you to uninstall and reinstall the app. Once you have reinstalled the app and signed in, you can check if you're able to add taxes.

If the steps provided above don't work, I recommend that you contact our customer support team regarding your taxes.

Let me know if you have questions, I'll be happy to help.
