So let's get this straight: is it your contract with the IRS that prohibits this, or is it your software use policy which forces us to the 5-efile limit? There's a huge difference.
The federal government doesn't care if you prepare taxes for other companies using TurboxTax if your are registered. What If I own 6 companies, get registered and want to use Trubotax?
The "professional" tax programs all gouge you with per-form fees that can quadruple the cost of a single tax return and it is in Intuit's own best interest to prevent you from exceeding 5 e-files. This limit has nothing at all to do with IRS regulations and has everything to do with squeezing more money out of its customers.
