I am just signing up for MTD on hmrc but wondered do i declare quickbooks as an agent or just register as business owner?

Hi there, thedarlknightcom.

When signing up for MTD on HMRC, you'll be reported as an agent if you're an accountant. However, if you're the owner of the company, I suggest to register as a business owner. Please check this article for additional details: Setting up MTD-eligible clients on HMRC and QuickBooks - MTD for accountants.

Also, you can refer to this article to learn the guidelines of submitting an MTD-compliant VAT: Making Tax Digital (MTD) - everything you need to know.

Please don't hesitate to ask if you have other question.
