Wow, you do have quite a bit going on! The only accounting software that I am aware of that would integrate with a tax software is QuickBooks Self-Employed. It integrates with TurboTax which is the tax software we recommend for small business owners. Check out this article which provides all of the features available in QuickBooks Self-Employed. You can also sign up for a discounted subscription directly from this article as well: https://fitsmallbusiness.com/quickbooks-self-employed/.
One important note is that QBSE does not allow you to 1099 contractors so you may need to go with QuickBooks Online to manage the sole prop that pays contractors. We have a free QuickBooks Online course that you can access directly from our website to get you up and running: https://fitsmallbusiness.com/free-quickbooks-online-tutorials/.
All the Best-
