Hi there, Rainbow8750.

Thanks for checking out the Community space.

I definitely understand that you need a tax ID field for your year-end statements. Unfortunately, we're unable to recommend or suggest what third-party application to use. 

To speed up the searching process, you can enter a keyword, like "year-end statements" in the search bar from the Apps menu or from our QuickBooks App Center. You may also look for some reviews online to be guided in choosing the right app for your business.

Additionally, I've included an article that will help you personalize the appearance of sales forms: Customize invoices, estimates, and sales receipts. This way, your customers will easily recognize your brand.

If I can be of any additional assistance, please don't hesitate to leave a comment below. I'll more than happy to help you again.
