Code & Regulations
First off, what is the authority for the positions espoused on this website?
The only authority for a tax position has to be the Internal Revenue Code ("IRC") and Regulations ("Regs") in addition to Court Cases.
What about IRS Publications?
Interestingly enough, IRS Publications are NOT authoritative for tax return positions. In Tax Court Summary Opinion 2014-14, the Tax Court states, regarding the deductibility of a payment to a divorced spouse as alimony:
The [IRS] publication appears to accurately portray the requirements of [IRC] section 71(b)(1) as discussed above. However, even if that were not the case, we note that informal IRS publications are not authoritative sources of Federal tax law; rather, applicable statutes, regulations, and judicial decisions constitute the authoritative sources of law that inform our [Tax Court] decisions.
With that in mind, what are the tax considerations covered on this website and in what authoritative reference is guidance provided?
