Harper is head of household in 2025 and earned $105,000 of wages and $9,000 of net Schedule C income. Harper paid $6,700 of state income tax and $4,100 of real property taxes, and also paid $1,200 of city income tax. What is the maximum SALT deduction Harper may claim on Schedule A?

$12,000, because head of household is not subject to the SALT limitation

$10,000, limited by the SALT cap (state and local income taxes plus property taxes combined)

$10,800, because city income tax is deductible in addition to the $10,000 cap

$5,000, because head of household uses the married filing separately SALT cap

Explanation

This question examines the SALT limitation for head of household filers with city income taxes. Harper paid $12,000 in eligible state and local taxes ($6,700 state income tax + $4,100 real property taxes + $1,200 city income tax), but the deduction is capped at $10,000. The correct answer is $10,000 because head of household filers are subject to the same $10,000 SALT cap as single and married filing jointly taxpayers, and city income taxes are included in the definition of deductible local taxes under IRC Section 164. Answer A ($12,000) incorrectly suggests head of household filers are exempt from the SALT limitation. Answer C ($5,000) wrongly applies the married filing separately limit. Answer D ($10,800) incorrectly treats city income tax as deductible in addition to the cap rather than subject to it. Harper should consider adjusting state and local tax withholdings or estimated payments to avoid exceeding the $10,000 annual limit, as any excess provides no federal tax benefit.

Sam is single in 2025 and owns a primary residence in State C and a vacation home in State D. Sam earned $210,000 of wages and $12,000 of net rental income from the vacation home, and paid $9,300 of State C income tax, $1,800 of State D income tax on the rental activity, $7,600 of real property taxes on the primary residence, and $4,900 of real property taxes on the vacation home. What is the maximum SALT deduction Sam may claim on Schedule A?

$5,000, because owning property in multiple states reduces the SALT cap by half

$10,000, limited by the SALT cap for single filers

$23,600, equal to total state income and real property taxes paid

$17,500, because only one home’s real property taxes are deductible

Explanation

This question examines the SALT deduction for single taxpayers with multiple properties across different states. Sam paid $23,600 in total state and local taxes ($9,300 State C income tax + $1,800 State D income tax + $7,600 primary residence property tax + $4,900 vacation home property tax), but the deduction is limited to $10,000 for single filers. The correct answer is $10,000 because the SALT cap applies to the aggregate of all eligible state and local taxes, including property taxes on multiple personal-use properties and income taxes paid to multiple states. Answer A ($23,600) ignores the statutory cap entirely. Answer C ($17,500) incorrectly suggests that only one home's property taxes are deductible, when in fact property taxes on all personal-use properties count toward the SALT deduction. Answer D ($5,000) wrongly applies a reduced cap for owning property in multiple states, which is not a provision in the tax code. Sam should consider whether converting the vacation home to a rental property might allow some property taxes to be deducted on Schedule E instead, though the State D income taxes would still count toward the SALT cap.

Casey is retired and files as single in 2025, receiving $44,000 of pension income and $16,000 of taxable Social Security benefits, plus $14,000 of long-term capital gains. Casey paid $4,400 of state income tax and $6,200 of real property taxes on a personal residence, and also paid $900 of personal property tax based on value. What is the maximum SALT deduction Casey may claim on Schedule A?

$11,500, equal to state income tax plus real property tax plus personal property tax

$10,600, because long-term capital gains are excluded when computing the SALT limitation

$10,000, limited by the SALT cap for single filers

$5,000, because retirees have a reduced SALT cap

Explanation

This question tests the SALT deduction for a retired single filer with capital gains and personal property taxes. Casey paid $11,500 in eligible state and local taxes ($4,400 state income tax + $6,200 real property taxes + $900 personal property tax), but the deduction is limited to $10,000 for single filers. The correct answer is $10,000 because the SALT cap applies regardless of income types (including capital gains) or taxpayer age/retirement status, and personal property taxes based on value are included in the SALT calculation. Answer A ($11,500) correctly identifies all eligible taxes but ignores the cap. Answer C ($5,000) wrongly suggests retirees have a reduced cap. Answer D ($10,600) incorrectly implies capital gains affect the SALT limitation calculation. Casey should consider tax-efficient investment strategies and whether the standard deduction might be more beneficial than itemizing, especially since $1,500 of SALT payments provide no federal tax benefit.

4

In 2025, Taylor and Quinn file separately (married filing separately). Taylor paid $4,100 of state income tax withholding and $3,600 of real property taxes on a jointly owned home (Taylor paid the full amount from a separate account). Taylor also paid $2,000 of mortgage interest and made $800 of charitable contributions. What is Taylor’s maximum SALT deduction on Schedule A?

$3,600, because only real property taxes are deductible when filing separately

$7,700, equal to the state income tax plus real property tax paid

$5,000, limited by the SALT cap for married filing separately

$10,000, because each spouse receives a separate $10,000 SALT limitation

Explanation

This question tests the SALT limitation for married filing separately taxpayers. Taylor paid $7,700 in state and local taxes ($4,100 state income tax + $3,600 real property taxes), but married filing separately taxpayers are limited to a $5,000 SALT deduction cap. The correct answer is $5,000 because the Tax Cuts and Jobs Act specifically limits married filing separately filers to half of the married filing jointly cap. Answer A ($7,700) incorrectly ignores the statutory limitation. Answer C ($10,000) wrongly suggests each spouse gets a full $10,000 cap when filing separately, which would create an advantage over joint filing. Answer D ($3,600) incorrectly limits the deduction to only real property taxes, when in fact both state income taxes and property taxes are eligible for the SALT deduction up to the cap. Taylor should consider whether filing jointly with Quinn might provide better overall tax benefits, as they would then be eligible for the full $10,000 SALT cap plus potentially more favorable tax brackets and other provisions.

5

In 2025, Pat and Lee file a joint return and have $140,000 of wages and $5,000 of interest income. They paid $8,200 of state income tax and $1,900 of personal property tax on vehicles (based on value), and $2,700 of real property taxes on their home; they also donated $3,000 to qualified charities. What is the maximum SALT deduction they may claim on Schedule A?

$12,800, equal to state income tax plus personal property tax plus real property tax

$10,000, limited by the SALT cap for married filing jointly

$8,200, because personal property taxes and real property taxes are not included in SALT

$5,000, because personal property taxes are capped at $5,000

Explanation

This question tests the inclusion of personal property taxes in the SALT deduction. Pat and Lee paid $12,800 in eligible state and local taxes ($8,200 state income tax + $1,900 personal property tax on vehicles + $2,700 real property taxes), but their deduction is limited to $10,000 for married filing jointly. The correct answer is $10,000 because personal property taxes based on value are included in the SALT deduction along with income and real property taxes, all subject to the overall cap. Answer A ($12,800) correctly identifies all eligible taxes but ignores the statutory limitation. Answer C ($5,000) incorrectly suggests a separate cap for personal property taxes. Answer D ($8,200) wrongly excludes both personal and real property taxes from SALT, when in fact all three types of taxes shown are eligible. Pat and Lee should ensure they're not confusing deductible personal property taxes (based on value) with non-deductible vehicle registration fees (based on weight or flat amounts), and consider whether the standard deduction might be more beneficial than itemizing.

6

Leslie is single in 2025 and earned $78,000 of wages and $6,000 of net self-employment income. Leslie paid $3,200 of state income tax and elected to pay $4,500 of state and local general sales tax instead of deducting state income tax; Leslie also paid $3,900 of real property taxes on a personal residence. Assuming Leslie itemizes, what is the maximum SALT deduction allowed on Schedule A?

$8,400, by deducting general sales tax and real property taxes (not state income tax)

$11,600, by deducting both state income tax and general sales tax plus real property taxes

$10,000, because the SALT cap increases when general sales tax is elected

$3,900, because only real property taxes qualify when sales tax is elected

Explanation

This question addresses the election to deduct general sales taxes instead of state income taxes. Leslie can choose to deduct either state income taxes OR general sales taxes (not both), plus real property taxes, subject to the SALT cap. If Leslie elects to deduct general sales taxes, the total eligible SALT would be $8,400 ($4,500 general sales tax + $3,900 real property taxes), which is below the $10,000 cap for single filers. The correct answer is $8,400 because taxpayers must choose between deducting state income taxes or general sales taxes - they cannot deduct both. Answer A ($11,600) incorrectly allows both income and sales taxes. Answer C ($10,000) wrongly suggests the cap increases when sales tax is elected. Answer D ($3,900) incorrectly excludes sales taxes from the deduction when elected. Leslie should compare the benefit of deducting $3,200 of state income taxes versus $4,500 of sales taxes and choose the option that provides the greater deduction, which in this case is the sales tax election resulting in a total SALT deduction of $8,400.

In 2025, Jordan and Casey file a joint return and have wage income of $310,000 and net rental income of $40,000 from a condominium in State B. They paid $18,500 of State A income tax withholding, $2,500 of State B income tax on the rental activity, and $9,200 of real property taxes on their primary residence; they also paid $6,000 of mortgage interest and donated $4,000 to qualified charities. What is the maximum state and local tax (SALT) deduction they may claim as an itemized deduction on Schedule A?

$5,000, limited by the SALT cap for married filing separately

$10,000, limited by the SALT cap for married filing jointly

$27,700, because State B income tax on rentals is not deductible

$30,200, equal to total state income taxes plus real property taxes paid

Explanation

This question tests the application of the $10,000 SALT deduction cap for married filing jointly taxpayers under current tax law. Jordan and Casey paid a total of $30,200 in state and local taxes ($18,500 State A income tax + $2,500 State B income tax + $9,200 real property taxes), which exceeds the statutory limitation. The correct answer is $10,000 because the Tax Cuts and Jobs Act (TCJA) limits the total deduction for state and local taxes to $10,000 for married filing jointly filers, regardless of the actual amount paid. Answer A ($30,200) is incorrect because it ignores the SALT cap entirely. Answer C ($5,000) incorrectly applies the married filing separately limit to joint filers. Answer D ($27,700) incorrectly suggests that State B income taxes are not deductible, when in fact all state income taxes are eligible for the SALT deduction subject to the overall cap. To optimize their tax situation, Jordan and Casey should consider timing strategies for state tax payments and explore whether any business-related state taxes might be deductible on other schedules.

8

Morgan is single and relocated mid-year from State X to State Y for work; in 2025 Morgan earned $92,000 of wages, had $2,000 of interest income, and paid $4,200 of State X income tax (final return) and $3,900 of State Y income tax (withholding). Morgan also paid $3,100 of real property taxes on a home in State Y and donated $1,500 to qualified charities. What is the maximum SALT deduction Morgan may claim on Schedule A?

$10,000, limited by the SALT cap for single filers

$7,800, because only the tax paid to the current state is deductible

$5,000, because the SALT cap is reduced for taxpayers who moved states

$11,200, the sum of state income taxes and real property taxes paid

Explanation

This question examines the SALT deduction limitation for single filers who have paid state income taxes to multiple states. Morgan paid a total of $11,200 in state and local taxes ($4,200 State X + $3,900 State Y + $3,100 real property taxes), but the deduction is capped at $10,000 for single filers under current law. The correct answer is $10,000 because the SALT cap applies to the combined total of all eligible state and local taxes, regardless of how many states are involved. Answer A ($11,200) incorrectly ignores the statutory cap. Answer C ($7,800) wrongly suggests that only taxes paid to the current state of residence are deductible, when in fact taxes paid to any state count toward the SALT deduction. Answer D ($5,000) incorrectly applies a reduced cap for taxpayers who moved states, which is not a provision in the tax code. Morgan should consider whether any state taxes might be creditable rather than deductible, and explore timing strategies for future tax payments to maximize the benefit within the $10,000 annual limit.

In 2025, Hayden and Jordan file a joint return and have $190,000 of wages and $10,000 of taxable interest. They paid $5,000 of state income tax, $4,900 of real property taxes, and $600 of local income tax; they also made $1,000 of charitable contributions. What is the maximum SALT deduction they may claim on Schedule A?

$10,500, equal to state income tax plus real property taxes plus local income tax

$9,900, because local income taxes are not included in SALT

$10,000, limited by the SALT cap for married filing jointly

$5,000, because the SALT cap is $5,000 per spouse on a joint return

Explanation

This question addresses the inclusion of local income taxes in the SALT deduction. Hayden and Jordan paid $10,500 in state and local taxes ($5,000 state income tax + $4,900 real property taxes + $600 local income tax), but their deduction is limited to $10,000 for married filing jointly. The correct answer is $10,000 because local income taxes are included in the definition of deductible state and local taxes under IRC Section 164, and the total of all eligible taxes is subject to the $10,000 cap for joint filers. Answer A ($10,500) correctly identifies all eligible taxes but ignores the cap. Answer C ($9,900) incorrectly excludes local income taxes from SALT. Answer D ($5,000) wrongly suggests the cap is $5,000 per spouse rather than $10,000 total for joint filers. Since Hayden and Jordan's total SALT is only slightly above the cap, they should consider adjusting their tax withholdings to avoid overpaying state and local taxes that provide no federal benefit.

Jamie is head of household in 2025 and earned $88,000 of wages and $3,000 of interest income. Jamie paid $5,500 of state income tax and $4,900 of real property taxes, and also paid $1,100 of local general sales tax; Jamie elects to deduct state income taxes rather than general sales taxes. What is the maximum SALT deduction Jamie may claim on Schedule A?

$9,400, because only real property taxes are subject to the SALT cap

$10,000, limited by the SALT cap

$11,500, because both state income tax and general sales tax may be deducted together

$5,000, because head of household has a reduced SALT cap

Explanation

This question addresses the SALT deduction for head of household filers who must choose between income and sales tax deductions. Jamie paid $10,400 in state income and property taxes ($5,500 state income tax + $4,900 real property taxes) and elected to deduct state income taxes rather than the $1,100 of general sales taxes. The total eligible SALT is $10,400, but the deduction is capped at $10,000 for head of household filers. The correct answer is $10,000 because head of household filers have the same $10,000 SALT cap as single and married filing jointly taxpayers, and the cap applies to whichever combination of taxes the taxpayer elects to deduct. Answer B ($11,500) incorrectly allows both income and sales taxes to be deducted together. Answer C ($5,000) wrongly applies a reduced cap for head of household. Answer D ($9,400) incorrectly suggests only property taxes are subject to the cap. Jamie made the right choice electing income taxes over sales taxes since the income taxes are higher, resulting in the maximum allowable SALT deduction of $10,000.
