Signature — who signs the partnership return

The responsible party is the person named on the EIN application (usually the main owner). If it changed, Form 8822-B is attached.

It is refundable and goes on Schedule 3, line 12. Personal use does not qualify.
General business credit — Form 3800
AviTax Pro supports the advanced manufacturing production credit (Form 7207): a credit you earned producing and selling eligible components, or a credit you bought from the producer under a transfer election (Schedule A (Form 3800)).
