Thanks for contacting us through the Community. I'd be happy to assist with figuring out why the pricing increased.
Were you on a limited time discount that ended recently? Did you make any subscription changes on your account? Have you reached out to the QuickBooks Self-Employed support team to see what the cause of the increase could be? In case you haven't yet, here's the link to the Self-Employed support team. Let me know if you have questions. I'll be on standby.
