Needed because documents of title don't automatically change ownership when someone dies
eg. Dr FMV of property at inception, CR Principal
eg. Dr Cash for interest received, Cr Income
811 looks at "what is income" - here we assume we know, and look to "who will be taxed"?
Many rules attacked this (multiple trust, grantor trust, throwback, etc.)
IRS hoist by its own petard: had attacked trusts used for bracket ride by treating others as income earners. Now Tp's use these cases against IRS, and IRS has to attack its own victories
Formerly, No tx if B was child/unborn.
Otherwise tax it again, w/ credit for tax already paid
In practice, elaborate "throwback" averaging procedure
EG. capital gains as part of corpus, exempt income is still income, allocation of fees between income and corpus, charitable and individual beneficiaries
Not all the taxable income may be distributable under fiduciary standards, and at the same time there may be distributions from corpus that are non-income gifts
Corpus or income distribs carry out DNI
But not gifts or specific bequests of specific sum or specific property:
663(a)(1)
DNI allocated 1st proportionately among first tier -- the mandatory income recipients. If excess, allocate proportionately among second tier -- the discretionary recipients: Sec. 662(a)(2)
