Once you have to file your business income and expenses will quickbooks send my information to hmrc to do my self assessment

Welcome to the Community, @thorpeshandymans. I'm here to provide information about filing your taxes in QuickBooks Self-Employed (QBSE).

QBSE is designed to help you track your deductions year-round to save you time when taxes are due. This is not a year-end tax filing tool. You can use and download the tax summary and tax details to have your accountant complete your taxes. To learn more details about filling in your tax return, you can visit this article: How to use QuickBooks Self-Employed reports to fill in your tax return.

For an additional guide in doing your Self Assessment tax, check out this link: How to Pay Self Assessment Tax. 

You can also visit our QuickBooks Self-Employed Overview article to know more information on how QBSE works. From here, you can find a list of frequently asked questions about the program as well as the answers for each of them. 

Don't hesitate to post again here if you have any other concerns about Self Assessment tax in QBSE. I'd be glad to assist you further. Keep safe.
