Tax Planning for Specialized Tax Matters
Domain 4: Tax Planning for Specialized Tax Matters
This domain gathers areas that do not sit inside a single Form 1040 or 1120: transfer taxes, fiduciary income taxation, multistate residency, international reporting, and equity compensation. Questions tend to be discrete but fact-heavy, so the exact threshold, rate, or form number is often the answer.
Transfer taxes
- The annual gift tax exclusion is $19,000 per donee for 2025 and applies only to present-interest gifts; gift splitting doubles it when both spouses consent on Form 709.
- The basic exclusion amount is $13,990,000 per person for 2025, unified between lifetime gifts and estates; portability transfers a deceased spouse's unused exclusion only if a timely Form 706 is filed.
- Taxable gifts are reported on Form 709 but generally produce no tax until the exclusion is exhausted, and gift tax paid is never deductible.
- Estates may elect alternate valuation six months after death when it lowers both the gross estate and the tax, and may claim the marital and charitable deductions.
Trusts and estates
- A simple trust distributes all income currently, makes no charitable contributions, and distributes no corpus; anything else is a complex trust.
- The distribution deduction is capped by distributable net income, which also fixes the character of what beneficiaries report.
- A §663(b) election treats distributions made within 65 days after year-end as paid in the prior year.
- Grantor trusts are disregarded and the grantor reports the income; compressed fiduciary brackets reach 37% at roughly $15,650 of 2025 trust taxable income.
Multistate and international
- Residency turns on domicile plus statutory residency tests such as 183 days and a permanent place of abode; nonresidents file on apportioned income with a credit for tax paid to the home state.
- FBAR (FinCEN 114) is required when aggregate foreign financial accounts exceed $10,000 at any point in the year; Form 8938 thresholds are higher and vary by filing status.
- The foreign earned income exclusion is $130,000 for 2025 and does not reduce self-employment tax; Form 1116 claims the foreign tax credit.
Worked example
An estate holds $18,000,000 of assets, owes $500,000 of deductible administration expenses, and the decedent made $1,000,000 of prior taxable gifts. Taxable estate is $17,500,000; adding adjusted taxable gifts gives $18,500,000; subtracting the $13,990,000 exclusion leaves $4,510,000 taxed at 40%, or $1,804,000.
Traps that cost marks
- Giving the annual exclusion to a gift of a future interest.
- Missing the portability election because no Form 706 was filed.
- Assuming the foreign earned income exclusion also eliminates self-employment tax or NIIT.
- Treating an incentive stock option exercise as tax-free for alternative minimum tax purposes.
