Income tax, basis and trust taxation
Income tax, basis and trust taxation covers how gifts, inheritances and trusts are taxed on income and on gain. The topic centers on tax basis, grantor trusts, estate and trust income tax and the net investment income tax.
What the topic covers
The guides describe how tax basis changes with gifts and inheritances, how spousal ownership affects inherited basis, and how irrevocable trusts affect basis at death. They explain grantor trust income tax and reimbursement, the net investment income tax as it applies to trusts, income tax of estates and revocable trusts after death, and how trust income is taxed across state lines.
Questions owners ask
Typical questions ask what happens when a gifted asset sells between the donor's basis and the gift-date value, what happens to basis when a gift is inherited back within one year, and what happens to bypass trust basis at the surviving spouse's death.
How the pieces connect
Basis connects the transfer tax system to the income tax system. An asset's basis decides the gain that a later sale reports, and the way property is transferred decides which basis the recipient takes. Trust classification then decides who reports the income. The calculators for this topic show the arithmetic with the reader's own figures.
