Well unfortunately this becomes a complicated area. Basically they are as follows:
Tax basis are books and records maintained in accordance with the tax laws.
GAAP are books and records maintained in accordance with generally accepted accounting principles.
704(b) are books and records maintained in accordance with the regulations under 1.704-1(b) and are extremely complicated but more in line with economic principles.
Other is exactly that - something different.

Also keep in mind the date of replies, as tax law changes.
