A married couple filing jointly has $\$310,000$ of wages, $\$4,000$ of taxable interest, $\$6,000$ of qualified dividends, and $\$40,000$ of long-term capital gains. They itemize deductions including $\$28,000$ of state income taxes and $\$12,000$ of real property taxes (both under IRC §164) and claim no credits. Under AMT rules (IRC §56), which adjustment is required for AMT calculation?

Add back $\$40,000$ of long-term capital gains only to the extent they exceed $\$3,000$

Add back $\$40,000$ of long-term capital gains because AMT taxes capital gains at ordinary rates

Add back $\$40,000$ of qualified dividends because dividends are preference items

Add back $\$40,000$ of state and local taxes (income and property) because they are not deductible for AMT

Explanation

The tax concept being tested is the disallowance of state and local taxes (SALT), including income and property taxes, as a deduction in computing AMTI under IRC §56(b)(1)(A)(ii). Key financial details include $28,000 in state income taxes and $12,000 in real property taxes, totaling $40,000 in SALT, combined with various income sources that may trigger AMT. The correct adjustment adds back the full $40,000 of SALT because these taxes are not deductible for AMT purposes, ensuring a broader tax base. Choice A is incorrect as long-term capital gains are not added back but are taxed at preferential rates under IRC §55(b)(3); Choice B is wrong because capital gains do not have a $3,000 threshold for AMT adjustments like net capital losses do in regular tax; Choice C is erroneous since qualified dividends are not preference items but receive preferential treatment in AMT similar to regular tax. To assess AMT exposure, compute AMTI by adding back non-deductible items like SALT to taxable income. Finally, compare the tentative AMT to regular tax liability after applying exemptions and rates to identify any additional tax due.

A single taxpayer has $\$195,000$ of wages, $\$1,100$ of taxable interest, $\$2,400$ of qualified dividends, and $\$10,000$ of long-term capital gains. The taxpayer exercised ISOs creating a $\$30,000$ spread at exercise and sold the shares in the same year in a disqualifying disposition. For AMT purposes, how does the ISO exercise generally affect AMTI compared with a same-year sale?

The spread is subtracted from AMTI because a disqualifying disposition creates an AMT deduction

The spread is treated as tax-exempt income for AMT and regular tax purposes

No AMT adjustment remains because the same-year disqualifying disposition generally eliminates the ISO AMT adjustment

The spread is always added to AMTI even if the shares are sold the same year

Explanation

The tax concept being tested is the impact of a disqualifying disposition on the ISO AMT adjustment under IRC §56(b)(3), where same-year sale typically aligns regular and AMT treatment. Key financial details involve a $30,000 ISO spread followed by same-year sale, with income levels suggesting possible AMT relevance. The correct effect is that no AMT adjustment remains because the disqualifying disposition includes the spread in regular taxable income, eliminating the need for AMT add-back. Choice A is incorrect as the adjustment is not required when the spread is already in regular income due to same-year sale; Choice C is wrong because it does not create a subtraction but avoids the addition; Choice D is erroneous since the spread is taxable compensation, not tax-exempt. To evaluate AMT exposure involving ISOs, check for disqualifying dispositions to determine if the spread is adjusted in AMTI. If no adjustment applies, proceed to compute tentative AMT and compare to regular tax.

A taxpayer (single) has $\$210,000$ of wages, $\$2,200$ of taxable interest, $\$3,000$ of qualified dividends, and $\$22,000$ of long-term capital gains. The taxpayer itemizes $\$24,000$ of SALT and exercised ISOs with a $\$18,000$ spread at exercise, holding the shares at year-end. Under AMT rules, which item is included in AMTI as an AMT adjustment or preference?

Neither the SALT deduction nor the ISO spread affects AMTI because both are already reflected in regular taxable income

Only the $\$22,000$ long-term capital gains are added back as an AMT preference item

Both the $\$24,000$ SALT deduction and the $\$18,000$ ISO spread increase AMTI

Only the $\$3,000$ qualified dividends are included as an AMT preference item

Explanation

The tax concept being tested is the identification of AMT adjustments and preferences, including SALT add-backs and ISO spreads under IRC §56. Key financial details include $24,000 in SALT and an $18,000 ISO spread with shares held, amid various income items. The correct items increasing AMTI are both the $24,000 SALT deduction and $18,000 ISO spread, as SALT is disallowed per IRC §56(b)(1)(A)(ii) and ISO spread is added per IRC §56(b)(3). Choice A is incorrect because qualified dividends are not preference items but taxed preferentially under IRC §55(b)(3); Choice B is wrong as long-term capital gains are not added back but receive favorable AMT rates; Choice D is erroneous since both items adjust AMTI as they are not fully reflected in regular taxable income. For AMT exposure analysis, aggregate adjustments like SALT and ISO spreads to taxable income to derive AMTI. Apply exemptions and rates to compute tentative tax, comparing to regular tax for final exposure.

A single taxpayer has $\$260,000$ of wages, $\$1,800$ of taxable interest, $\$3,200$ of qualified dividends, and $\$18,000$ of long-term capital gains. The taxpayer itemizes deductions including $\$35,000$ of state and local taxes (SALT) under Internal Revenue Code (IRC) §164 and $\$18,000$ of mortgage interest; no other adjustments apply. For Alternative Minimum Tax (AMT) purposes under IRC §55–§59, which adjustment is required in computing alternative minimum taxable income (AMTI)?

Subtract the $\$18,000$ long-term capital gain because capital gains are excluded from AMTI

Add back the $\$18,000$ mortgage interest because personal interest is disallowed for AMT

Deduct the $\$10,000$ SALT limitation amount as an AMT adjustment because AMT allows the capped SALT deduction

Add back the full $\$35,000$ SALT itemized deduction because state and local taxes are not deductible for AMT

Explanation

The tax concept being tested is the adjustment for state and local taxes (SALT) in computing alternative minimum taxable income (AMTI) under IRC §56, as SALT deductions allowed for regular tax are disallowed for AMT. Key financial details include the taxpayer's itemized deductions of $35,000 in SALT and $18,000 in mortgage interest, alongside income sources such as wages, interest, dividends, and capital gains that determine potential AMT exposure. The correct adjustment adds back the full $35,000 SALT deduction because IRC §56(b)(1)(A)(ii) explicitly disallows deductions for state and local taxes in AMTI computation. Choice A is incorrect because AMT does not permit any SALT deduction, including the $10,000 cap applicable only to regular tax under IRC §164(b)(6); Choice C is wrong as qualified residence interest is deductible for AMT under IRC §56(b)(1)(C); Choice D is erroneous since long-term capital gains are included in AMTI and taxed at preferential rates, not excluded per IRC §55(b)(3). To analyze AMT exposure, start by calculating taxable income and adding back disallowed deductions like SALT and ISO adjustments. Then, subtract the AMT exemption and apply AMT rates to determine if tentative minimum tax exceeds regular tax, ensuring comprehensive review of all potential adjustments.

A married couple filing jointly has $\$360,000$ of wages, $\$3,000$ of taxable interest, $\$7,000$ of qualified dividends, and $\$30,000$ of long-term capital gains. One spouse exercised ISOs resulting in a $\$55,000$ spread at exercise, and the shares were held through year-end. Under IRC §56(b)(3), which statement best describes the AMT treatment?

The $\$55,000$ spread is deductible for AMT because it is taxed under regular tax rules

The $\$55,000$ spread is ignored for both regular tax and AMT until the stock is sold

The $\$55,000$ spread increases AMTI as an AMT adjustment in the year of exercise

Only 50% of the $\$55,000$ spread is an AMT preference item because it relates to capital assets

Explanation

The tax concept being tested is the inclusion of the ISO bargain element in AMTI under IRC §56(b)(3) when shares are held through year-end. Key financial details feature a $55,000 ISO spread with no disposition, combined with joint filing status and diverse income sources amplifying AMT potential. The correct statement is that the $55,000 spread increases AMTI as an adjustment in the exercise year, as it is not taxed regularly until sale. Choice B is incorrect because the spread is not deductible for AMT but added back; Choice C is wrong as the spread is recognized for AMT at exercise, not deferred to sale; Choice D is erroneous since only the full spread is added, without a 50% reduction for capital assets. For AMT exposure analysis, add ISO spreads from non-disposed exercises to regular taxable income to form AMTI. Then, after exemption, calculate tentative AMT and compare to regular tax to determine liability.

A married couple filing jointly has $\$420,000$ of wages, $\$6,500$ of taxable interest, $\$8,000$ of qualified dividends, and $\$25,000$ of long-term capital gains. They itemize deductions including $\$45,000$ of SALT and $\$20,000$ of mortgage interest; no other AMT adjustments apply. For AMT purposes under IRC §56, which adjustment is required?

Add back $\$45,000$ of SALT because SALT is not deductible in computing AMTI

Subtract $\$8,000$ of qualified dividends because AMT excludes qualified dividends from AMTI

Add back only the portion of SALT exceeding the $\$10,000$ limitation because AMT permits the capped deduction

Add back $\$20,000$ of mortgage interest because AMT disallows all mortgage interest

Explanation

The tax concept being tested is the complete disallowance of state and local taxes (SALT) in AMTI computation under IRC §56(b)(1)(A)(ii), without regard to the regular tax cap. Key financial details encompass $45,000 in SALT and $20,000 in mortgage interest as deductions, paired with high wage income and capital gains that heighten AMT risk. The correct adjustment adds back the full $45,000 SALT because AMT rules prohibit any SALT deduction, broadening the tax base. Choice B is incorrect as AMT does not allow even the $10,000 capped SALT deduction from regular tax under IRC §164(b)(6); Choice C is wrong because qualified mortgage interest is deductible for AMT per IRC §56(b)(1)(C); Choice D is erroneous since qualified dividends are not subtracted but are taxed preferentially in AMT under IRC §55(b)(3). To evaluate AMT exposure, adjust taxable income by adding back items like SALT and reviewing for other preferences. Then, calculate tentative AMT after exemption phase-out and compare to regular tax to quantify exposure.

7

A single taxpayer has $\$185,000$ of wages, $$900$ of taxable interest, $\$2,100$ of qualified dividends, and $\$12,000$ of long-term capital gains. The taxpayer claims itemized deductions including $\$22,000$ of SALT and $\$9,000$ of charitable contributions; no other AMT adjustments apply. Under IRC §56, which adjustment is required for AMT calculation?

Subtract $\$12,000$ of long-term capital gains because AMT excludes capital gains from AMTI

Add back $\$9,000$ of charitable contributions because they are disallowed for AMT

Add back $\$900$ of taxable interest because interest is a tax preference item

Add back $\$22,000$ of SALT because state and local taxes are disallowed for AMT

Explanation

The tax concept being tested is the AMT adjustment for state and local taxes (SALT) under IRC §56, where SALT deductions are added back to compute AMTI. Key financial details include $22,000 in SALT and $9,000 in charitable contributions as itemized deductions, along with income components like wages and capital gains influencing AMT applicability. The correct adjustment adds back the $22,000 SALT because IRC §56(b)(1)(A)(ii) disallows SALT deductions entirely for AMT. Choice B is incorrect as charitable contributions are fully deductible for AMT under IRC §56(b)(1)(G); Choice C is wrong because long-term capital gains are included in AMTI but not subtracted, receiving preferential rates per IRC §55(b)(3); Choice D is erroneous since taxable interest is included in AMTI without adjustment as a preference item. For AMT exposure analysis, begin with regular taxable income and adjust for disallowed deductions such as SALT. Subsequently, apply the AMT exemption and rates to the resulting AMTI to determine if AMT liability arises.

8

A taxpayer (single) has $\$230,000$ of wages, $\$2,500$ of taxable interest, $\$4,500$ of qualified dividends, and $\$15,000$ of long-term capital gains. The taxpayer exercised incentive stock options (ISOs) during the year, acquiring shares with a $\$20,000$ spread between fair market value and exercise price at exercise, and held the shares at year-end (no disposition). Under AMT rules (IRC §56(b)(3)), how does exercising the ISOs impact AMT?

The $\$20,000$ spread is included in AMTI as an AMT adjustment in the year of exercise

No AMT impact occurs until the shares are sold because ISO spread is ignored for AMT

The $\$20,000$ spread is treated as a negative AMT adjustment because ISO income is deductible for AMT

The $\$20,000$ spread is included in regular taxable income and therefore is not an AMT adjustment

Explanation

The tax concept being tested is the AMT adjustment for incentive stock options (ISOs) under IRC §56(b)(3), where the bargain element at exercise is added to AMTI if shares are held at year-end. Key financial details include a $20,000 ISO spread with shares retained, alongside high wages and other income increasing AMT susceptibility. The correct treatment includes the $20,000 spread in AMTI as an adjustment because it represents income deferred for regular tax but recognized for AMT. Choice A is incorrect as the ISO spread is not ignored for AMT but added in the exercise year per IRC §56(b)(3); Choice B is wrong because the spread is a positive adjustment, not negative or deductible; Choice D is erroneous since the spread is excluded from regular taxable income until sale, necessitating the AMT adjustment. To analyze AMT exposure, identify ISO exercises without same-year disposition and add the spread to taxable income. Compute AMTI, deduct the exemption, and apply AMT rates to assess if tentative tax exceeds regular tax.

9

A single taxpayer has $\$140,000$ of wages, $\$1,200$ of taxable interest, $\$1,800$ of qualified dividends, and $\$60,000$ of long-term capital gains. The taxpayer itemizes deductions including $\$16,000$ of SALT and $\$7,000$ of charitable contributions; no other AMT adjustments apply. Which adjustment is required for AMT calculation under IRC §56?

Add back $\$7,000$ of charitable contributions because they are disallowed for AMT

Subtract $\$16,000$ of SALT because AMT provides an additional SALT deduction

Add back $\$60,000$ of long-term capital gains because AMT treats capital gains as preference items

Add back $\$16,000$ of SALT because state and local taxes are disallowed for AMT

Explanation

The tax concept being tested is the AMT adjustment requiring the add-back of state and local taxes (SALT) deducted for regular tax, as per IRC §56(b)(1)(A)(ii). Key financial details include $16,000 in SALT and $7,000 in charitable contributions, with substantial capital gains potentially affecting AMT calculations. The correct adjustment adds back the $16,000 SALT because it is not allowable as a deduction in AMTI. Choice A is incorrect as charitable contributions remain deductible for AMT under IRC §56(b)(1)(G); Choice C is wrong because long-term capital gains are not treated as preference items but receive favorable rates in AMT per IRC §55(b)(3); Choice D is erroneous since AMT does not provide an additional SALT deduction but disallows it entirely. For AMT exposure determination, compile all income and add back disallowed deductions like SALT to derive AMTI. Apply the appropriate exemption and tax rates to AMTI, then compare the tentative minimum tax to regular tax liability.

10

A taxpayer (single) has $\$130,000$ of wages, $$700$ of taxable interest, $\$1,200$ of qualified dividends, and $\$5,000$ of long-term capital gains. The taxpayer itemizes $\$9,500$ of SALT and has no other AMT adjustments. Under IRC §56, which adjustment is required for AMT calculation?

Add back $\$5,000$ of long-term capital gains because AMT taxes gains at ordinary rates

Add back $\$9,500$ of SALT because state and local taxes are disallowed for AMT

Subtract $\$1,200$ of qualified dividends because dividends are excluded from AMTI

Subtract $\$700$ of taxable interest because AMT excludes interest income

Explanation

The tax concept being tested is the AMT add-back for state and local taxes (SALT) under IRC §56(b)(1)(A)(ii). Key financial details include $9,500 in SALT with lower income but still requiring AMT check. The correct adjustment adds back the $9,500 SALT because it is not deductible for AMT. Choice B is incorrect as long-term capital gains are taxed preferentially, not at ordinary rates in AMT; Choice C is wrong because taxable interest is included in AMTI without subtraction; Choice D is erroneous since qualified dividends are part of AMTI without exclusion. For AMT exposure determination, adjust taxable income by adding SALT. Apply exemption and rates to AMTI to assess excess over regular tax.
