How do I change account from self employed to business with an employee

Let me help you with upgrading your QuickBooks account, arealgoodclean-g. 

I'll take it as you want to change your subscription from QuickBooks Self-Employed (QBSE) account to QuickBooks Online (QBO) version. In this case, we'll have to purchase a QBO account for you to add an employee since the two are different versions. Let me guide you how:

1. Go to this page: QuickBooks Online Plans & Pricing.
2. Select your preferred version.
3. Continue with the on-screen instructions to successfully purchase one.

If you no longer use the QBSE account, you can cancel it to avoid a double subscription. Here's how:

1. Sign in to QuickBooks Self-Employed in a web browser.
2. Click the Gear icon on the top menu
3. Select Billing Info.
4. Tap Cancel subscription.

Feel free to visit our Getting Started With QuickBooks Online page for more insight about running your business in your Online account.
