TCP Area I: Individuals & Personal Financial Planning

Gross income, adjustments & deductions, QBI, credits, AMT, passive activity rules, retirement & education planning, and the investment-income surtaxes

Gross income & exclusions §61 / §101–139

The starting point for every individual return is the §61 definition: gross income means "all income from whatever source derived." This is a deliberately broad, catch-all rule. Once an item is income, it is taxable unless the Code provides a specific exclusion. On TCP you are expected to reason from this default and then identify whether an exclusion applies, rather than memorize a closed list.

Common inclusions

Key exclusions

Generally INCLUDEDGenerally EXCLUDED
Wages, tips, bonusesGifts and inheritances
Taxable interest and ordinary dividendsMunicipal-bond interest
Schedule C net profitLife-insurance death benefits
Pre-2019 alimony receivedPost-2018 alimony received
Taxable pension/IRA distributionsReturn of basis; Roth qualified distributions
Up to 85% of Social SecurityQualified scholarship (tuition portion)
Cancellation of debt (general rule)§121 home-sale gain within limits
Exam trap: the broad §61 rule means the burden is on the taxpayer to find an exclusion. If a fact pattern describes an economic benefit and no specific exclusion fits, treat it as gross income. Watch for items that look excludable but are not, such as the room-and-board portion of a scholarship or punitive damages.

Adjustments to income (above-the-line) §62

Adjustments, also called deductions for AGI or above-the-line deductions, are subtracted from gross income to arrive at adjusted gross income (AGI). They are available to every taxpayer regardless of whether they itemize. Because AGI is the floor or ceiling for many later phaseouts and limitations, an above-the-line deduction is generally more valuable than a below-the-line one of the same size.

Self-employment related

Savings and other adjustments

Why AGI matters AGI is the hinge of the individual return. It sets the 7.5% medical floor, the charitable percentage ceilings, IRA and education phaseouts, the §1411 surtax MAGI threshold, and credit phaseouts. Lowering AGI through an above-the-line deduction can unlock multiple downstream benefits at once, which is the planning angle TCP rewards.
Exam trap: do not confuse the above-the-line self-employed health insurance deduction with itemized medical expenses. SE health premiums go above the line (no AGI floor); other unreimbursed medical costs are itemized and subject to the 7.5%-of-AGI floor.

Itemized deductions vs standard deduction §63 / §67 / §213

From AGI, a taxpayer subtracts the greater of the standard deduction or total itemized deductions to reach taxable income. The standard deduction is a flat, inflation-adjusted amount that varies by filing status, with an additional amount for taxpayers who are age 65 or older or blind (2026, inflation-adjusted). Most taxpayers take the standard deduction; itemizing is worthwhile only when allowable itemized deductions exceed it.

Itemized deduction categories (Schedule A)

Charitable gift typeAGI ceiling
Cash to public charities60% of AGI
Long-term capital-gain property (FMV) to public charities30% of AGI
Capital-gain property to private foundations20% of AGI

Appreciated long-term capital-gain property donated to a public charity is generally deducted at fair market value (no recognition of the built-in gain), making it a powerful planning tool versus selling and donating cash.

Exam trap: the 2%-of-AGI miscellaneous itemized deductions (unreimbursed employee expenses, tax-preparation fees, investment-advisory fees) remain suspended and are not deductible. Do not let a fact pattern lure you into deducting them. Investment interest (a separate category) is still allowed within its net-investment-income limit.

Qualified business income deduction §199A

The §199A deduction lets eligible individuals deduct up to 20% of qualified business income (QBI) from pass-through entities and sole proprietorships. QBI is the net of qualified items of income, gain, deduction, and loss from a U.S. trade or business. It excludes investment items (capital gains, dividends, interest not allocable to the business), reasonable compensation paid to an S-corporation owner, and guaranteed payments to a partner.

How the limitation tiers work

The mechanics depend on taxable income relative to the threshold (2026, inflation-adjusted; a higher amount for married filing jointly).

  1. Below the threshold: the deduction is simply 20% of QBI, with no SSTB restriction and no wage/property limit. This is the cleanest tier.
  2. Within the phase-in range: the SSTB limitation and the wage-and-property limitation phase in proportionally over the range above the threshold.
  3. Above the upper end of the range: the limits apply fully. An SSTB receives no deduction, and a non-SSTB deduction is capped by the wage-and-property test.

The two limits

The overall cap

After the per-business calculation, the total deduction is limited to 20% of (taxable income − net capital gain). Net capital gain here includes qualified dividends. This overall limit is applied last.

§199A lesser-of test (above threshold, non-SSTB) The allowed amount for each business is the LESSER of:
(1) 20% of QBI, or
(2) the greater of [50% of W-2 wages] OR [25% of W-2 wages + 2.5% of UBIA].
Then the combined result is capped by 20% of (taxable income − net capital gain).
StepExample figure
QBI from business$400,000
20% of QBI$80,000
W-2 wages paid by business$120,000
50% of W-2 wages$60,000
Tentative deduction (lesser of $80k and $60k)$60,000
Overall cap: 20% of (taxable income − net capital gain)apply last
Exam trap: the wage/property limit and the SSTB rule only bite once taxable income exceeds the threshold. A high-earning consultant (SSTB) gets zero, while a high-earning manufacturer (non-SSTB) is limited by wages and property rather than denied. Below the threshold, both get the full 20% regardless of activity.

Tax credits §21–25

Credits reduce tax liability directly, dollar-for-dollar, after taxable income and the tentative tax have been computed. They fall into two families: nonrefundable credits, which can reduce tax only to zero, and refundable credits, which can generate a refund beyond the tax owed. Many credits phase out as AGI or MAGI rises.

Refundable (can exceed tax)Nonrefundable (limited to tax)
Earned income credit (EIC)Child & dependent care credit
Additional child tax credit (refundable portion of CTC)Credit for other dependents
American Opportunity credit (40% refundable)Lifetime Learning credit
Premium tax credit (advance/refundable)Retirement savings (saver's) credit
Foreign tax credit
Adoption credit (carryforward, nonrefundable)

Family credits

Education and savings credits

Other credits

Exam trap: distinguish a credit from a deduction. A $1,000 credit reduces tax by $1,000 regardless of bracket. A $1,000 deduction reduces tax only by $1,000 times the marginal rate (for example $220 in the 22% bracket). When a question asks which produces the larger benefit, the credit almost always wins.

Individual AMT §55–59

The alternative minimum tax is a parallel tax system designed to ensure that taxpayers with substantial economic income cannot eliminate their liability through preferences and deductions. The taxpayer computes tax twice and pays the higher of regular tax or the tentative minimum tax.

Building AMTI

Start with regular taxable income, then add back preferences and make adjustments to arrive at alternative minimum taxable income (AMTI):

From AMTI to AMT

  1. Subtract the AMT exemption, which is itself phased out as AMTI rises above a threshold (both the exemption and the phaseout start are inflation-adjusted for 2026).
  2. Apply the AMT rate schedule (26% / 28%) to taxable excess to get the tentative minimum tax (TMT).
  3. AMT owed equals the excess, if any, of TMT over the regular tax.
Common AMT addbacks (preferences & adjustments)SALT (state and local taxes)
ISO bargain element at exercise
Private-activity bond interest (tax-exempt for regular tax)
Depreciation differences (accelerated vs AMT method)
Standard deduction (added back when used)
Think "SIP-DS": these items are deductible or excluded for regular tax but not for AMT.

The AMT credit

AMT caused by timing items (such as depreciation differences or an ISO exercise where the stock is held) generates a minimum tax credit that carries forward and offsets regular tax in future years, preventing permanent double taxation. AMT caused by exclusion items (such as the SALT addback) does not generate a credit.

Exam trap: exercising an ISO and holding the shares creates AMT income equal to the bargain element even though no cash changes hands and no regular-tax income is recognized. This is a classic planning pitfall; a disqualifying disposition in the same year can avoid the AMT hit by converting it to a regular-tax event.

Passive activity, at-risk & investment surtaxes §469 / §1411

Three loss-limitation regimes and several surtaxes police investment and rental income at the individual level. Losses pass through three gates in order: basis, then at-risk, then passive activity.

Passive activity loss rules (§469)

Rental real-estate exceptions

At-risk limitation (§465)

Separately, losses are deductible only to the extent the taxpayer is at risk, generally cash and the adjusted basis of property contributed plus recourse debt. Nonrecourse financing (except qualified real-property nonrecourse) does not increase the at-risk amount. The at-risk screen is applied before the passive-activity screen.

Investment-income surtaxes

Exam trap: the $25,000 rental allowance and the 3.8% NIIT both turn on MAGI, but in opposite directions. High MAGI phases out the loss allowance and phases in the surtax. A single fact pattern can trigger both, so watch the MAGI figure carefully.

Retirement, education & gift planning PFP

Personal financial planning on TCP is about applying the tax rules strategically: deferring income, managing brackets, choosing between pre-tax and after-tax savings, and transferring wealth efficiently. The technical rules below are the toolkit; the exam tests your ability to recommend the right tool for a client's situation.

Traditional vs Roth IRA

FeatureTraditional IRARoth IRA
ContributionsMay be deductible (active-participant phaseout)Never deductible; MAGI phaseout on ability to contribute
GrowthTax-deferredTax-free
Qualified distributionsTaxable as ordinary incomeTax-free if 5-year rule met and age 59½, death, disability, or first home
RMDs for the ownerRequired beginning at age 73None during the owner's lifetime

Planning angle: a Roth favors taxpayers who expect higher future rates; a traditional account favors those who expect lower rates in retirement. A Roth conversion in a low-income year (for example, early retirement before Social Security begins) fills up low brackets at a known rate and removes future RMDs.

Education funding

Gift and estate basics

Planning levers to recognizeTax-deferral: max out pre-tax plans to lower current AGI.
Roth conversions: convert in low-bracket years to lock in low rates and kill future RMDs.
Bracket management: spread income across years to avoid spiking into higher rates or surtaxes.
Tax-loss harvesting: realize capital losses to offset gains (up to $3,000 of ordinary income annually, excess carried forward).
Exam trap: the carryover-basis vs step-up distinction drives gifting strategy. Gift appreciated property during life to shift future gain (carryover basis preserves the low basis), but hold highly appreciated property until death so heirs get the step-up and the gain disappears. Recommending the wrong one is a common planning error the exam targets.
