Question 1

1. Chen deducts the full $600,000 because the excess business loss limitation applies only when total income is under $200,000
2. Chen applies the excess business loss limitation; any disallowed amount carries forward as a net operating loss (correct answer)
3. The S corporation must retain and carry forward the loss at the entity level and cannot pass it through
4. Chen must treat the loss as a suspended passive loss even though he materially participates

Explanation: This question tests the excess business loss limitation for high-income S corporation shareholders. Chen receives a $600,000 ordinary loss from an S corporation but has $700,000 of wage income, providing substantial income against which to offset losses. The excess business loss limitation for single taxpayers (approximately $305,000 for 2024) still applies, limiting the current deduction and creating an NOL carryforward for the excess. Answer A incorrectly creates an income threshold exemption, Answer C incorrectly requires entity-level retention, and Answer D incorrectly treats active losses as passive. The tax planning principle is that the excess business loss limitation applies regardless of the taxpayer's income level, preventing large current-year business loss deductions.

Question 2

1. River may deduct the full $900,000 and reduce taxable income to $0 because corporations are not subject to any limitation on net operating loss deductions
2. River may deduct up to $720,000 (80% of $900,000) in 2024, leaving $180,000 taxable income and carrying forward $280,000 (correct answer)
3. River may deduct only $450,000 (50% of taxable income) because corporate net operating loss deductions are capped at 50%
4. River must carry the 2022 net operating loss back 2 years before using any carryforward in 2024

Explanation: This question tests whether a C corporation can fully eliminate taxable income using post-2017 net operating losses. River Co. has $900,000 of taxable income and a $1,000,000 NOL carryforward from 2022, which is subject to the 80% limitation. The maximum NOL deduction is $720,000 (80% × $900,000), leaving $180,000 of taxable income and a $280,000 NOL carryforward. Answer A incorrectly allows full elimination of taxable income, Answer C incorrectly applies a 50% limitation, and Answer D incorrectly requires carrybacks for post-2017 NOLs. The tax planning framework is that C corporations cannot reduce taxable income below 20% of the pre-NOL amount when using post-2017 NOLs, ensuring minimum tax revenue.

Question 3

1. Both shareholders may deduct their full allocated losses because the excess business loss limitation applies only at the S corporation level
2. Each shareholder applies the excess business loss limitation on their own return; any disallowed amount carries forward as a net operating loss (correct answer)
3. Only Jordan is subject to the excess business loss limitation because the limitation applies only when wages are under $50,000
4. Both shareholders must carry back any disallowed loss 3 years and carry forward 15 years

Explanation: This question tests how the excess business loss limitation applies to multiple S corporation shareholders with different income levels. Alex and Jordan each receive $450,000 of ordinary loss allocation, with Alex having $200,000 of wages and Jordan having only $20,000. Each shareholder independently applies the excess business loss limitation on their own return based on their individual income and filing status. Answer A incorrectly states the limitation applies only at entity level, Answer C incorrectly creates a wage threshold for the limitation, and Answer D incorrectly prescribes carryback periods. The tax planning principle is that pass-through losses are tested for excess business loss limitation at each owner's level, creating different outcomes for owners with varying income levels.

Question 4

1. Falcon may deduct $1,500,000 of net operating loss to reduce taxable income to $0 and carry forward $500,000
2. Falcon may deduct $1,200,000 of net operating loss (80% limitation), leaving $300,000 taxable income and carrying forward $800,000 (correct answer)
3. Falcon may deduct $750,000 of net operating loss (50% limitation), leaving $750,000 taxable income and carrying forward $1,250,000
4. Falcon must carry the 2023 net operating loss back 3 years before any 2024 deduction is allowed

Explanation: This question tests the 80% limitation on post-2017 net operating losses for C corporations. Falcon Inc. has $1,500,000 of taxable income and a $2,000,000 NOL carryforward from 2023, subject to the 80% limitation. The maximum NOL deduction is $1,200,000 (80% × $1,500,000), leaving $300,000 of taxable income and an $800,000 NOL carryforward. Answer A incorrectly allows full offset to zero, Answer C incorrectly applies a 50% limitation, and Answer D incorrectly requires carrybacks for 2023 NOLs. The key tax planning principle is that C corporations cannot eliminate all taxable income with post-2017 NOLs, ensuring a minimum 20% tax base remains.

Question 5

1. Deduct the full $700,000 loss in 2023 because material participation eliminates any limitation on current-year business losses
2. Apply the excess business loss limitation to cap the current-year deduction; carry forward the disallowed portion as a net operating loss (correct answer)
3. Elect to carry the entire $700,000 loss back 2 years because net operating losses must be carried back before carryforward
4. Reclassify the loss as a capital loss so it can offset unlimited ordinary income in 2023

Explanation: This question tests the application of excess business loss limitations for married filing jointly taxpayers with S corporation losses. Sam and his spouse have $170,000 of combined income ($150,000 wages + $20,000 interest) and Sam receives a $700,000 ordinary loss from an S corporation where he materially participates. The excess business loss limitation for married filing jointly in 2023 is approximately $610,000 (indexed for inflation), meaning a portion of the $700,000 loss exceeds the threshold and must be carried forward as an NOL. Answer A incorrectly ignores the excess business loss limitation, Answer C incorrectly states NOLs must be carried back, and Answer D incorrectly attempts to recharacterize ordinary losses as capital losses. The tax planning framework is to calculate the excess business loss limitation based on filing status and carry forward any disallowed amounts as NOLs rather than current deductions.

Question 6

1. Treat the full $500,000 as fully deductible because excess business loss limitations apply only to wages and self-employment income
2. Limit the current-year deduction under the excess business loss rules; the disallowed portion becomes a net operating loss carryforward (correct answer)
3. Disallow the loss entirely at the partnership level because partnerships cannot pass through net operating losses
4. Convert the disallowed portion into a capital loss carryforward reported on Schedule D

Explanation: This question tests the excess business loss limitation for partnership losses allocated to partners with only portfolio income. Partner B receives a $500,000 ordinary loss from a partnership and has $150,000 of portfolio income ($100,000 dividends + $50,000 interest) but no wages or self-employment income. The excess business loss limitation applies to limit the current deduction, with the disallowed portion becoming an NOL carryforward. Answer A incorrectly excludes portfolio income from the limitation, Answer C incorrectly disallows losses at the partnership level, and Answer D incorrectly converts ordinary losses to capital losses. The key principle is that the excess business loss limitation applies to all noncorporate taxpayers regardless of income type, with disallowed amounts preserved as NOL carryforwards.

Question 7

1. Deduct $700,000 of net operating loss and reduce taxable income to $0 because 2020 net operating losses are not subject to the 80% limitation
2. Deduct $560,000 of net operating loss (80% of $700,000), leaving $140,000 taxable income and a $340,000 carryforward (correct answer)
3. Deduct $630,000 of net operating loss (90% limitation), leaving $70,000 taxable income and a $270,000 carryforward
4. No net operating loss deduction is allowed because carryforwards are limited to 3 years for corporations

Explanation: This question tests whether a 2020 net operating loss is subject to the 80% limitation for C corporations. Spruce Inc. has $700,000 of taxable income and a $900,000 NOL from 2020, which arose during the CARES Act period but is still subject to the 80% limitation for use in 2024. The maximum NOL deduction is $560,000 (80% × $700,000), leaving $140,000 of taxable income and a $340,000 carryforward. Answer A incorrectly treats 2020 NOLs as unlimited, Answer C incorrectly applies a 90% limitation, and Answer D incorrectly limits carryforward periods. The key principle is that while 2020 NOLs had special carryback provisions under the CARES Act, they remain subject to the 80% limitation when carried forward to post-2020 years.

Question 8

1. Deduct $1,000,000 of net operating loss in 2023, reducing taxable income to $0 and carrying forward $200,000
2. Deduct $800,000 of net operating loss in 2023 (80% limitation), leaving $200,000 taxable income and carrying forward $400,000 (correct answer)
3. Deduct $600,000 of net operating loss in 2023 (60% limitation), leaving $400,000 taxable income and carrying forward $600,000
4. No net operating loss deduction is allowed because net operating losses cannot be used in years with positive taxable income

Explanation: This question tests the 80% taxable income limitation on net operating loss deductions for C corporations with post-2017 NOLs. Birch Co. has $1,000,000 of taxable income before NOL deduction and a $1,200,000 NOL carryforward from 2022, which is subject to the 80% limitation. The maximum NOL deduction is $800,000 (80% × $1,000,000), leaving $200,000 of taxable income and a $400,000 NOL carryforward. Answer A incorrectly allows a full deduction to zero, Answer C incorrectly applies a 60% limitation that doesn't exist, and Answer D incorrectly states NOLs cannot be used with positive income. The tax planning principle is that C corporations with post-2017 NOLs must retain at least 20% of pre-NOL taxable income, ensuring some tax liability remains.

Question 9

1. Priya deducts the full $300,000 loss because S corporation losses are not subject to any limitation at the shareholder level
2. Priya applies the excess business loss limitation; any disallowed loss carries forward as a net operating loss (correct answer)
3. The S corporation must carry the loss forward at the entity level and may not pass it through to Priya
4. Priya must carry back the loss 5 years because business losses always have a carryback period

Explanation: This question tests the excess business loss limitation for S corporation losses passed through to individual shareholders. Priya receives a $300,000 ordinary loss from an S corporation and has only $50,000 of other income ($40,000 wages + $10,000 interest). The excess business loss limitation for single taxpayers limits the deductible loss, with the excess becoming an NOL carryforward. Answer A incorrectly exempts S corporation losses from shareholder-level limitations, Answer C incorrectly requires entity-level loss carryforwards, and Answer D incorrectly mandates loss carrybacks. The tax planning principle is that S corporation losses flow through to shareholders who must then apply individual-level limitations, including the excess business loss rules.

Question 10

1. Partner E deducts the full $350,000 because portfolio income is excluded when computing any business loss limitation
2. Partner E applies the excess business loss limitation; any disallowed amount is treated as a net operating loss carryforward (correct answer)
3. The loss is nondeductible because partnership losses cannot offset portfolio income
4. Partner E must carry back the loss 2 years and may not carry it forward

Explanation: This question tests the excess business loss limitation for partnership losses when the partner has only portfolio income. Partner E receives a $350,000 ordinary business loss and has $55,000 of portfolio income ($30,000 interest + $25,000 dividends) but no earned income. The excess business loss limitation for single taxpayers applies to limit the current deduction, with disallowed amounts becoming NOL carryforwards. Answer A incorrectly excludes portfolio income from consideration, Answer C incorrectly prohibits business losses from offsetting portfolio income, and Answer D incorrectly mandates carrybacks. The key principle is that the excess business loss limitation creates NOL carryforwards regardless of the taxpayer's income composition, preserving tax benefits for future years.

Question 11

1. Partner C deducts the full $500,000 loss because excess business loss rules do not apply to partnership losses
2. Partner C applies the excess business loss limitation; the disallowed portion is carried forward as a net operating loss (correct answer)
3. Partner C must treat the partnership loss as a capital loss limited to $3,000 per year
4. Partner C may carry the partnership loss back 2 years and recover prior-year wage withholding

Explanation: This question tests the excess business loss limitation for partnership losses allocated to individual partners. Partner C receives a $500,000 ordinary business loss and has $300,000 of wage income, triggering the excess business loss limitation for single taxpayers. The deductible loss is limited to the threshold amount (approximately $305,000 for 2023), with the excess carried forward as an NOL. Answer A incorrectly exempts partnership losses from the limitation, Answer C incorrectly recharacterizes ordinary losses as capital losses, and Answer D incorrectly allows loss carrybacks. The tax planning principle is that all business losses from pass-through entities are aggregated and subject to the excess business loss limitation at the partner level, regardless of entity type.

Question 12

1. Use $80,000 of the 2022 net operating loss (80% limitation) and carry forward all of the 2016 loss because pre-2018 losses cannot be used in 2024
2. Use the 2016 net operating loss first to offset $90,000, then use $8,000 of the 2022 net operating loss (80% of remaining $10,000), leaving $2,000 taxable income (correct answer)
3. Use the 2022 net operating loss first to offset $100,000 in full, leaving $0 taxable income
4. No net operating loss deduction is allowed because taxable income is under $250,000

Explanation: This question tests the ordering and application of pre-2018 and post-2017 net operating losses. Elm Co. has $100,000 of taxable income, a 2016 NOL of $90,000 (no limitation), and a 2022 NOL of $200,000 (80% limitation). The correct order applies the 2016 NOL first, reducing taxable income to $10,000, then applies the 2022 NOL limited to $8,000 (80% × $10,000), leaving $2,000 of taxable income. Answer A incorrectly prohibits using pre-2018 losses, Answer C incorrectly allows full offset to zero, and Answer D incorrectly creates an income threshold. The key tax planning principle is to sequence NOL usage to maximize benefit, using unlimited pre-2018 NOLs before limited post-2017 NOLs.

Question 13

1. Deduct $100,000 of net operating loss in 2024 and report $200,000 taxable income (correct answer)
2. Deduct $240,000 of net operating loss (80% limitation), leaving $60,000 taxable income and a $0 carryforward
3. Deduct $0 because net operating loss deductions are not allowed in years after 2020
4. Carry back the $100,000 to 2022 automatically and do not deduct any net operating loss in 2024

Explanation: This question tests the basic application of post-2017 net operating losses for C corporations. Cypress Co. has $300,000 of taxable income and a $100,000 NOL carryforward from 2022. Since the NOL ($100,000) is less than 80% of taxable income ($240,000), the entire NOL can be deducted, leaving $200,000 of taxable income. Answer B incorrectly applies the 80% limitation to the full income amount, Answer C incorrectly prohibits NOL deductions after 2020, and Answer D incorrectly requires automatic carrybacks. The key principle is that the 80% limitation caps the NOL deduction but doesn't require reducing smaller NOLs that fall within the limit.

Question 14

1. Deduct $2,000,000 of net operating loss to reduce taxable income to $0 and carry forward $1,000,000
2. Deduct $1,600,000 of net operating loss (80% of taxable income), leaving $400,000 taxable income and carrying forward $1,400,000 (correct answer)
3. Deduct $1,000,000 of net operating loss (50% of taxable income), leaving $1,000,000 taxable income and carrying forward $2,000,000
4. No net operating loss deduction is allowed because net operating losses may only offset capital gains for corporations

Explanation: This question tests whether a C corporation can minimize taxable income using post-2017 net operating losses. Redwood Co. has $2,000,000 of taxable income and a $3,000,000 NOL carryforward from 2021, which is subject to the 80% limitation. The maximum NOL deduction is $1,600,000 (80% × $2,000,000), leaving $400,000 of taxable income and a $1,400,000 NOL carryforward. Answer A incorrectly allows reduction to zero, Answer C incorrectly applies a 50% limitation, and Answer D incorrectly restricts NOLs to capital gains offset. The tax planning framework recognizes that even with substantial NOL carryforwards, C corporations must pay tax on at least 20% of pre-NOL income when using post-2017 losses.

Question 15

1. Willow must carry the 2024 net operating loss back 2 years and may elect to waive the carryback
2. Willow may carry the 2024 net operating loss back 5 years because corporate net operating losses have a 5-year carryback period
3. Willow generally may not carry back a 2024 net operating loss and instead carries it forward indefinitely, subject to the 80% taxable income limitation in future years (correct answer)
4. Willow may deduct the 2024 net operating loss only as a special deduction limited to 10 years, after which it expires

Explanation: This question tests the carryback rules for net operating losses generated after 2017. Willow Co. generated a $400,000 NOL in 2024 and asks about carrying it back to prior years. Under current law, NOLs arising in tax years beginning after 2017 generally cannot be carried back (except for certain farming losses and insurance companies), but instead carry forward indefinitely subject to the 80% limitation. Answer A incorrectly allows a 2-year carryback, Answer B incorrectly states a 5-year carryback period, and Answer D incorrectly limits the carryforward to 10 years. The tax planning principle is that post-2017 NOLs provide future tax benefits only, not retroactive refunds, requiring corporations to plan for cash flow without carryback opportunities.

Question 16

1. Apply the 2021 net operating loss first, limited to 80% of taxable income, and carry forward the 2017 loss because pre-2018 losses must be used last
2. Apply the 2017 net operating loss first (no 80% limitation), then apply the 2021 net operating loss subject to the 80% limitation on remaining taxable income (correct answer)
3. Apply both net operating losses in full to reduce taxable income below zero and carry back the resulting loss 2 years
4. No net operating loss deduction is permitted because multiple-year net operating losses cannot be combined in one tax year

Explanation: This question tests the ordering rules when a corporation has both pre-2018 and post-2017 net operating losses. Maple Inc. has $350,000 of taxable income, a 2017 NOL of $120,000 (not subject to 80% limitation), and a 2021 NOL of $500,000 (subject to 80% limitation). The correct approach is to apply pre-2018 NOLs first without limitation, reducing taxable income to $230,000, then apply post-2017 NOLs limited to 80$184,000 = 80% × $230,000). Answer A incorrectly reverses the order, Answer C incorrectly allows full use creating negative income, and Answer D incorrectly prohibits combining multiple year NOLs. The key tax planning principle is to maximize NOL utilization by using unlimited pre-2018 NOLs before applying limited post-2017 NOLs.

Question 17

1. Apply the 2017 net operating loss first in full, then apply the 2022 net operating loss limited to 80% of remaining taxable income (correct answer)
2. Apply the 2022 net operating loss first in full, then apply the 2017 net operating loss limited to 80% of remaining taxable income
3. Apply both net operating losses in full to reduce taxable income to $0 because multiple carryforwards are not subject to the 80% limitation
4. No net operating loss deduction is allowed because pre-2018 net operating losses expired after 5 years

Explanation: This question tests complex ordering when multiple net operating losses from different periods exist. Lakeview Inc. has $1,000,000 of taxable income, a 2017 NOL of $300,000 (unlimited), and a 2022 NOL of $900,000 (80% limited). The correct approach uses the 2017 NOL first without limitation, reducing taxable income to $700,000, then applies the 2022 NOL limited to $560,000 (80% × $700,000), leaving $140,000 of final taxable income. Answer B incorrectly reverses the order, Answer C incorrectly allows full deduction, and Answer D incorrectly states pre-2018 NOLs expired. The tax planning framework prioritizes using unlimited pre-2018 NOLs before limited post-2017 NOLs to maximize overall deduction.

Question 18

1. Deduct $80,000 in 2023 and carry forward $120,000 because the 80% limitation does not apply when taxable income is below $100,000
2. Deduct $64,000 in 2023 (80% of $80,000), leaving $16,000 taxable income and carrying forward $136,000 (correct answer)
3. Deduct $40,000 in 2023 (50% of $80,000), leaving $40,000 taxable income and carrying forward $160,000
4. Deduct $0 in 2023 because net operating losses can only be used in years with taxable income over $250,000

Explanation: This question tests the 80% limitation calculation for smaller amounts of corporate taxable income. Ivy Co. has $80,000 of taxable income and a $200,000 NOL carryforward from 2022, subject to the 80% limitation. The maximum NOL deduction is $64,000 (80% × $80,000), leaving $16,000 of taxable income and a $136,000 carryforward. Answer A incorrectly waives the limitation for small income amounts, Answer C incorrectly applies a 50% limitation, and Answer D incorrectly creates an income threshold for NOL usage. The key principle is that the 80% limitation applies regardless of income level, requiring all C corporations to retain 20% of pre-NOL taxable income.

Question 19

1. Granite deducts $420,000 and has $0 taxable income because the net operating loss deduction can fully offset corporate taxable income
2. Granite deducts $336,000 (80% of $420,000), leaving $84,000 taxable income and carrying forward $264,000 (correct answer)
3. Granite deducts $210,000 (50% of $420,000), leaving $210,000 taxable income and carrying forward $390,000
4. Granite deducts $0 in 2023 and must carry the 2022 net operating loss back to 2020 first

Explanation: This question tests the application of the Tax Cuts and Jobs Act (TCJA) net operating loss (NOL) limitation for C corporations, specifically the 80% taxable income limitation for NOLs arising in tax years beginning after December 31, 2017. Granite Co. has $420,000 of taxable income before the NOL deduction and a $600,000 NOL carryforward from 2022, which is subject to the post-2017 rules. Under IRC Section 172(a)(2), NOLs arising after 2017 can only offset up to 80% of taxable income, meaning Granite can deduct $336,000 (80% × $420,000), leaving $84,000 of taxable income. Answer A is incorrect because the 100% offset rule only applies to NOLs arising before 2018; Answer C incorrectly applies a 50% limitation that doesn't exist in the tax code; Answer D is incorrect because post-2017 NOLs cannot be carried back (except for specific COVID-19 relief that doesn't apply here). The remaining $264,000 of unused NOL ($600,000 - $336,000) carries forward indefinitely to future tax years. When dealing with post-2017 NOLs, always remember the 80% limitation applies to the taxable income in the year of use, not to the NOL itself, and these losses can only be carried forward, never back.

Question 20

1. Partner D deducts the full $900,000 because married filing jointly taxpayers are exempt from the excess business loss limitation
2. Partner D applies the excess business loss limitation and carries forward any disallowed amount as a net operating loss (correct answer)
3. The partnership deducts the loss at the entity level and Partner D reports only net income, so no limitation applies to the partner
4. Partner D must recharacterize the loss as a charitable contribution carryforward

Explanation: This question tests the excess business loss limitation for married filing jointly taxpayers with partnership losses. Partner D receives a $900,000 ordinary business loss and has $550,000 of other income ($500,000 wages + $50,000 portfolio). The excess business loss limitation for married filing jointly (approximately $610,000 for 2023) limits the current deduction, with excess amounts becoming NOL carryforwards. Answer A incorrectly exempts married taxpayers from the limitation, Answer C incorrectly applies entity-level deductions for partnerships, and Answer D incorrectly recharacterizes business losses as charitable contributions. The tax planning framework requires aggregating all business income and losses to test against filing status thresholds, preserving excess losses as NOLs.
