Over 30% of the EA SEE Part 1 exam blueprint covers deductions. The most common failure point isn't forgetting a rule; it's misapplying a limitation under pressure. Candidates memorize the $10,000 SALT cap but fail when a question mixes state income tax with foreign property tax, testing the judgment of what qualifies to be in the cap in the first place.
Schedule A deductions are specific personal expenses taxpayers can use to reduce their adjusted gross income (AGI), but only if the total exceeds their standard deduction. For the EA exam, you must master the AGI floors, dollar caps, and debt limits for medical expenses (IRC §213), state and local taxes (IRC §164), mortgage interest (IRC §163), and charitable gifts (IRC §170).
Key facts
- Official form: IRS Form 1040, Schedule A, Itemized Deductions

- SALT limitation: Capped at $10,000 per return ($5,000 if Married Filing Separately).
- Medical limitation: Deductible only for expenses exceeding 7.5% of Adjusted Gross Income (AGI).
- Mortgage interest limitation: Deductible on up to $750,000 of acquisition indebtedness ($375,000 if MFS).
- Exam section: Special Enrollment Examination (SEE) Part 1: Individuals.
What Is Schedule A and Why Is It Heavily Tested?
Schedule A is the IRS form used by taxpayers who choose to itemize deductions instead of taking the standard deduction. The core decision is simple: if your total eligible itemized deductions are greater than the standard deduction for your filing status, you itemize.
The EA exam tests this concept by creating scenarios that require practitioner-level judgment. The questions are not designed to ask, "Is property tax deductible?" They are designed to test if you know how that property tax interacts with state income tax under the $10,000 SALT cap defined in IRC §164.

The most expensive mistake candidates make is focusing on the type of expense instead of the limitation. Knowing medical bills are potentially deductible is easy. Knowing you must first calculate a 7.5% AGI floor and subtract it is what earns you points on the exam. Test your judgment with VoraPrep's free EA practice questions to see how these limitations appear in exam-style questions.
To make the initial decision clear, here is when a taxpayer would choose to itemize over taking the standard deduction.
| Filing Status (2026) | Standard Deduction | Itemize If Total Deductions Exceed... |
|---|---|---|
| Single | $14,600 | $14,600 |
| Married Filing Jointly | $29,200 | $29,200 |
| Married Filing Separately | $14,600 | $14,600 |
| Head of Household | $21,900 | $21,900 |
Which Schedule A Rules Are Most Tested on the EA Exam?
Your success on Schedule A questions requires mastering four major categories and their specific, complex limitations. The exam will force you to apply these thresholds, not just recite them.
Medical and Dental Expenses (IRC §213)
You can deduct qualified medical expenses not reimbursed by insurance, but only the amount that exceeds 7.5% of your Adjusted Gross Income (AGI). This AGI "floor" is the most critical part of the rule.- What's deductible: Prescription drugs, payments to doctors, hospital care, and medically necessary capital improvements (to the extent the cost exceeds the increase in home value).
- What's not: Non-prescription medicines, cosmetic surgery, or general wellness items like gym memberships.
- The Trap: A question will provide a taxpayer's AGI and their total medical bills. The tempting wrong answer is the total medical bill amount. The correct answer requires you to first calculate the 7.5% AGI floor and subtract it from the total expenses.
State and Local Taxes (SALT) (IRC §164)
The SALT deduction is capped at $10,000 per tax return ($5,000 for Married Filing Separately). This is a hard ceiling.A taxpayer adds up their state and local property taxes PLUS their choice of EITHER state and local income taxes OR state and local general sales taxes.
- What's included in the cap: State/local real estate taxes, state/local personal property taxes, and state/local income taxes (or sales taxes).
- What's NOT included: Federal income taxes, Social Security taxes, excise taxes, or foreign real estate taxes.
- The Trap: An exam question will list $8,000 in state income tax, $4,000 in local property tax, and $2,000 in foreign property tax. The wrong answer adds them all. The correct approach is to identify qualifying SALT ($8k + $4k = $12k) and then apply the $10,000 cap. The foreign property tax is not deductible on Schedule A, though it may be eligible for a foreign tax credit on Form 1116.
Home Mortgage Interest (IRC §163(h))
Interest is deductible on a loan secured by a main or second home, but the rules are strict. For debt incurred after December 15, 2017, interest is deductible only on up to $750,000 of acquisition indebtedness ($375,000 if MFS). Acquisition indebtedness is debt used to buy, build, or substantially improve the home that secures the debt. This "use of proceeds" test is critical.- Home Equity Debt: Interest on home equity loans is deductible only if the proceeds are used to buy, build, or substantially improve the taxpayer's home securing the loan. If the funds are used for personal expenses like paying off credit cards, the interest is not deductible.
- The Trap: A taxpayer has a $600,000 original mortgage and a $100,000 home equity loan used to pay for a wedding. Many candidates see "home equity loan" and assume the interest is deductible within the overall debt limit. It is not. The use of the proceeds makes the interest non-deductible personal interest.
Charitable Contributions (IRC §170)
Deductions for gifts to qualified charities are subject to AGI limitations that vary by the type of gift and recipient.- Cash to Public Charities: Limited to 60% of AGI.
- Capital Gain Property to Public Charities: Limited to 30% of AGI, based on the property's Fair Market Value (FMV).
- Cash to Private Non-Operating Foundations: Limited to 30% of AGI.
- Excess Contributions: Amounts exceeding the AGI limits can generally be carried forward for up to five years.
What's No Longer Deductible? A Key TCJA Change
Prior to the Tax Cuts and Jobs Act (TCJA), taxpayers could deduct certain miscellaneous itemized deductions to the extent they exceeded 2% of AGI. This included items like unreimbursed employee expenses, tax preparation fees, and investment expenses.The TCJA suspended the deduction for miscellaneous itemized deductions subject to the 2% floor. The EA exam may test your knowledge of this change by including these items in a list of expenses and forcing you to correctly exclude them from the total.
| Deduction Category | IRC Section | Key Limitation (2026 Tax Year) | Common Exam Trap |
|---|---|---|---|
| Medical Expenses | §213 | Deductible only to the extent they exceed 7.5% of AGI. | Forgetting to calculate and subtract the AGI floor. |
| State & Local Taxes (SALT) | §164 | Capped at $10,000 per return ($5,000 MFS). | Including non-qualifying taxes (e.g., foreign property tax). |
| Mortgage Interest | §163(h) | Interest on up to $750,000 of acquisition debt. | Deducting interest on home equity debt not used to improve the home. |
| Charitable Gifts (Cash) | §170 | Limited to 60% of AGI for gifts to public charities. | Misapplying the AGI limit for the type of charity or property. |
How Do I Calculate Deductible Mortgage Interest? (A Worked Example)
Let's walk through a problem that tests your judgment on mortgage interest. This requires more than memorizing the $750,000 limit.
Scenario: In February 2026, Maya and Ben, who file a joint return, purchase a primary residence for $900,000. They take out an $800,000 mortgage to acquire the home. In July 2026, they take out a $50,000 home equity loan on the same residence and use the proceeds to pay for their child's college tuition. They paid a total of $32,000 in interest on the first mortgage and $3,000 in interest on the home equity loan.What is the amount of deductible mortgage interest Maya and Ben can claim on their Schedule A?
Step 1: Analyze the First Mortgage The rule under IRC §163(h)(3) limits the deduction to interest on $750,000 of acquisition indebtedness.- Their mortgage is $800,000, which exceeds the limit.
- They can only deduct the interest attributable to the first $750,000 of principal.
- Calculation: ($750,000 limit / $800,000 total loan) * $32,000 total interest = $30,000
- Maya and Ben used the $50,000 for college tuition, a personal expense.
- Conclusion: None of the $3,000 in interest on the home equity loan is deductible. It is non-deductible personal interest.
- Deductible interest from first mortgage: $30,000
- Deductible interest from home equity loan: $0
- Total Deductible Mortgage Interest: $30,000

Can You Pass These EA Exam-Style Schedule A Questions?
Theory is one thing; application is everything. Here are a few sample questions modeled after the real exam.
Sample Question 1 In 2026, Quinn has an AGI of $60,000 and paid $8,000 in qualified medical expenses. She itemizes her deductions. What is the amount of medical expense deduction she can claim on her Schedule A? A) $8,000 B) $6,000 C) $3,500 D) $4,500> Explanation: The correct answer is C. The medical expense deduction is limited to the amount exceeding 7.5% of AGI. First, calculate Quinn's AGI floor: $60,000 AGI * 7.5% = $4,500. Then, subtract this floor from her total medical expenses: $8,000 - $4,500 = $3,500. Answer A is a distractor for those who forget the AGI limit. Answer D is the AGI floor itself, not the deductible amount.

> Explanation: The correct answer is A. For cash contributions to a public charity, the deduction is limited to 60% of the taxpayer's AGI. Rachel's AGI is $100,000, so her limit is $100,000 * 60% = $60,000. Even though she contributed $70,000, her deduction for the current year is capped at $60,000. The remaining $10,000 can be carried forward for up to five years.
Sample Question 3 Sam paid $8,000 in state income tax and $7,000 in property tax on his main home for 2026. He files as Married Filing Jointly. What is the maximum State and Local Tax (SALT) deduction Sam can claim on his Schedule A? A) $15,000 B) $10,000 C) $8,000 D) $7,000> Explanation: The correct answer is B. The SALT deduction is capped at $10,000 per return. Sam's total state and local taxes are $8,000 (income) + $7,000 (property) = $15,000. However, due to the limitation, he can only deduct $10,000. Answer A is the total tax paid, which ignores the cap.
What's the Best Strategy for Schedule A Questions on Exam Day?
Effective performance on the exam requires both knowledge and strategy.
First, connect Schedule A to the overall tax formula. Remember that itemized deductions are only relevant if they exceed the standard deduction. A question may require you to calculate the total itemized deductions and then compare it to the standard deduction to make the final decision. This links Schedule A to the broader topic of how tax computation and rates are determined.
Second, manage your time effectively. The exam is timed. If a question involves multiple charitable contributions with different AGI limits, it may be designed to be time-consuming. Flag it and return later. Your goal is to maximize points across the entire testlet. To prepare, you must understand the full EA exam format and structure.
In your final review, create a one-page summary of the key numerical limitations:
- Medical: 7.5% of AGI floor
- SALT: $10,000 cap ($5,000 MFS)
- Mortgage Debt: $750,000 principal limit ($375,000 MFS)
- Charity (Cash to Public): 60% of AGI ceiling
- Charity (LTCG Property to Public): 30% of AGI ceiling
Drill these until they are automatic. When you see "medical expenses," your brain should immediately retrieve "7.5% floor." This frees up mental energy for the actual analysis required by the scenario.
