Ann Althouse has some interesting information.
If true, it means that the tax preparers have some level of control over tax policy.
Taxes can be a way to get revenue, a way to enact social policy, or a way to give breaks to one's friends - but using taxes as a way to benefit the tax preparation companies is... well, it's astounding.
Not that the IRS is at fault, per se. The tax preparation companies apparently threatend to sue. But then again, the government runs the courts, so the government could presumably find a way to prevent that.
There are other suggestions as to why the IRS lacks a tax preparation form in the comments.
That is all.
