A business has $100,000 in taxable income before any NOL deduction. It also has a $90,000 Net Operating Loss carryforward from a prior year. How much of that NOL can the business deduct this year?
If you said $90,000, you just fell for one of the most common traps on the SEE Part 2 exam. The correct answer is $80,000. The exam isn't testing if you know what an NOL is; it's testing if you can apply its strict limitations under pressure. This is a test of judgment, not just memory. This 7-day sprint will build that judgment, turning traps into points on your score report.
To pass the EA exam, you must master the "ordinary and necessary" standard for business expenses under IRC §162. Key tested areas include vehicle costs (Standard vs. Actual methods), the home office deduction's "exclusive and regular use" test under IRC §280A, Net Operating Loss (NOL) limitations (80% of taxable income per IRC §172), and Excess Business Loss (EBL) thresholds.

Day 1: How to Apply the 'Ordinary and Necessary' Standard
The foundation of all business deductions is the "ordinary and necessary" principle from Internal Revenue Code §162. An ordinary expense is common and accepted in the taxpayer's trade. A necessary expense is helpful and appropriate for the business.
On the SEE Part 2 exam, this concept is the filter for every scenario. The test doesn't just ask what is deductible; it presents situations that test the boundaries of this rule. Examiners love to weave in personal expenses or lavish costs to see if you can correctly disallow them.
For every practice question, apply this four-part test:
- Is this expense common in this specific industry?
- Is it helpful for generating revenue?
- Is any part of it personal?
- Is it lavish or extravagant under the circumstances?
This framework also extends to compensation. An expense for an owner-employee's salary is only deductible to the extent that it is "reasonable" for the services performed. The exam might present a scenario with an unusually high salary in a small S-corp to test if you can identify this issue.

Day 2-4: How to Handle the Core Deductions and Their Traps
These three days focus on the most calculation-intensive expense categories. The objective is to master the rules, their interactions, and the specific traps the IRS examiners build around them.
How Are Business Vehicle Expenses Tested?
You will be required to calculate vehicle deductions. The exam will test your ability to choose the correct and most advantageous method for the taxpayer.| Feature | Standard Mileage Rate | Actual Expense Method |
|---|---|---|
| Calculation | Business miles × IRS-provided rate | (Total costs + Depreciation) × Business use % |
| What's Included | Rate covers gas, oil, repairs, insurance, depreciation, registration. | Track all actual costs: gas, oil, repairs, insurance, tires, registration, lease payments, depreciation. |
| Separate Deductions | You can still deduct business-related parking fees and tolls. | Parking and tolls are also deducted separately. |
| Recordkeeping | Requires a mileage log (dates, purpose, miles). | Requires receipts for all costs plus a mileage log to prove business use percentage. |
What Are the Traps in the Home Office Deduction?
The home office deduction under IRC §280A is a favorite exam topic because its requirements are strict. A portion of the home must be used exclusively and regularly as the taxpayer's principal place of business.| Method | Calculation | Key Limitation & Trap |
|---|---|---|
| Simplified | $5 per square foot (max 300 sq ft, or $1,500). | Easy to calculate, but no carryover of unused deductions is allowed. |
| Actual Expenses | Business % of actual home costs (mortgage interest, taxes, utilities, insurance, depreciation). | Limited to business gross income. However, any unused deduction can be carried forward to future years. |
Navigating Deductions for Meals, Travel, and Entertainment
The Tax Cuts and Jobs Act of 2017 (TCJA) drastically changed these rules, and the exam ensures you know the new landscape.- Entertainment Expenses: Under IRC §274, these are 100% non-deductible. This includes tickets to sporting events or concerts, even if you discuss business.
- Business Meals: Deductible at 50% of the cost, provided the expense is not lavish and the taxpayer (or an employee) is present.
- Travel Expenses: Costs for transportation and lodging are fully deductible when traveling away from your "tax home" for business. Meals are still subject to the 50% limit.
The most common trap is lumping a deductible meal with non-deductible entertainment. If a client dinner costs $300 and tickets to a game afterward cost $400, your deduction is $150 (50% of the meal), not $350.
Applying the 80% Rule for Net Operating Losses (NOLs)
An NOL occurs when a business's deductions exceed its income. The rules under IRC §172 were updated significantly by the TCJA.- Carryforward Only: NOLs arising in 2018 and later are carried forward indefinitely. The 2-year carryback was eliminated for most businesses.
- The 80% Limitation: The NOL deduction in any given year is limited to 80% of taxable income, calculated before taking the NOL deduction itself.
- Farming Exception: Certain farming losses have a special rule allowing a two-year carryback. Expect this exception to appear as a potential distractor.
How Does the Excess Business Loss (EBL) Limit Work?
This rule under IRC §461(l) imposes a final cap on the total net business losses a non-corporate taxpayer can deduct in a year.- Thresholds: The limits are indexed for inflation. For 2025, the thresholds were $289,000 for single filers and $578,000 for joint filers. The exam will provide the specific year's numbers.
- Treatment: Any loss exceeding this threshold is not deductible in the current year. Instead, it is treated as an NOL carryforward to the following year, where it then becomes subject to the 80% NOL limitation.
Deducting Start-up vs. Organizational Costs
The IRS allows businesses to deduct or amortize the costs of getting started, but they are treated separately.- Start-up Costs (IRC §195): Costs to investigate creating or acquiring a business.
- Organizational Costs (IRC §248): Costs to form a corporation or partnership.
- The Rule: You can elect to deduct up to $5,000 of start-up costs AND up to $5,000 of organizational costs in the year business begins. Each $5,000 allowance is reduced dollar-for-dollar by total costs in its respective category exceeding $50,000. Any remaining costs are amortized over 180 months.
Capital Expenditures vs. Repairs: A Key Distinction
The exam will test your ability to distinguish between a currently deductible repair and a capital expenditure that must be depreciated.- Repair: A cost that keeps property in its normal operating condition (e.g., fixing a leak, repainting). These are deductible in the current year.
- Capital Expenditure: A cost that results in a betterment, restoration, or adaptation of the property to a new use (e.g., a new roof, a building addition). These costs must be capitalized and depreciated over time using methods like MACRS, §179, or bonus depreciation.

Day 5: How to Solve a Complex Deduction Problem
Let's walk through a multi-step problem that mirrors the complexity of the SEE Part 2 exam.
- Home Office: Priya uses a 300 sq ft room exclusively for her business in her 2,500 sq ft home. Total home expenses (mortgage interest, taxes, utilities, insurance) were $20,000. Allowable depreciation on the office portion is $1,200.
- Vehicle: She drove her car 20,000 total miles; her log shows 15,000 were for business. Her actual vehicle expenses (gas, insurance, repairs) totaled $8,000. Allowable depreciation for the business portion is $3,000. She also paid $400 in business-related parking. The exam provides a 2026 standard mileage rate of 67 cents per mile.
- Meals & Entertainment: Priya spent $3,000 on valid business meals with clients. She also spent $1,000 taking a prospective client to a concert.
- NOL: She has a $20,000 NOL carryforward from 2025. Her 2026 taxable income before the NOL deduction is $90,000.
Step 1: Calculate Home Office Deduction
You must compare methods to find the best outcome.- Simplified Method: 300 sq ft × $5/sq ft = $1,500
- Actual Method:
- Business Use Percentage: 300 sq ft / 2,500 sq ft = 12%
- Allocated Expenses: $20,000 × 12% = $2,400
- Add Depreciation: $1,200
- Total Actual Deduction: $2,400 + $1,200 = $3,600
- Decision: The Actual Method is better. Home Office Deduction: $3,600
Step 2: Calculate Business Vehicle Deduction
Again, you must compare both methods.- Standard Mileage Method:
- (15,000 business miles × $0.67/mile) + $400 parking = $10,050 + $400 = $10,450
- Actual Expense Method:
- Business Use Percentage: 15,000 / 20,000 total miles = 75%
- Allocated Actual Expenses: $8,000 × 75% = $6,000
- Add Depreciation: $3,000
- Add Parking: $400
- Total Actual Deduction: $6,000 + $3,000 + $400 = $9,400
- Decision: The Standard Mileage Method is better. Business Vehicle Deduction: $10,450
Step 3: Calculate Meals & Entertainment Deduction
This step tests the strict disallowance rule.- Business Meals: $3,000 × 50% = $1,500
- Entertainment (Concert): $1,000 × 0% = $0
- Total Meals & Entertainment Deduction: $1,500
Step 4: Calculate NOL Deduction
This tests the 80% limitation.- NOL Carryforward: $20,000
- Taxable Income before NOL: $90,000
- 80% Limitation: $90,000 × 80% = $72,000
- Since the NOL ($20,000) is less than the limit ($72,000), the full $20,000 is deductible.
- NOL Deduction: $20,000
Day 6: How to Convert Knowledge into Exam Points
Memorizing rules is not enough. You must drill with exam-style questions that force you to apply judgment under pressure. The VoraPrep adaptive engine has over 3,000 questions with detailed explanations designed to build this exact skill.
Sample Q1: Home Office Trap
A self-employed taxpayer qualifies for the home office deduction. Their actual expenses and depreciation total $3,200. The simplified method would yield a $1,400 deduction. Their net income from the business before the home office deduction is only $2,500. Which of the following is true?
Sample Q2: Start-up Cost Calculation
A new corporation begins business on July 1, 2026, and incurs $54,000 in qualifying start-up costs. What is the maximum start-up cost deduction the corporation can take on its 2026 tax return?
- Phase-out: The initial $5,000 deduction is reduced by the amount costs exceed $50,000. $5,000 - ($54,000 - $50,000) = $1,000.
- Amortization: The remaining $53,000 ($54,000 - $1,000) is amortized over 180 months. For 2026 (6 months), this is ($53,000 / 180) × 6 = $1,767.
- Total Deduction: $1,000 + $1,767 = $2,767.
- Correct Answer: C.
Day 7: What Is Your Pre-Exam Checklist?
With the core knowledge in place, this final day is about strategy.
- Time Management: Budget 2-3 minutes for any question requiring a comparison of two methods (e.g., Vehicle, Home Office). Budget 60-90 seconds for direct rule questions. If a calculation stumps you, flag it and move on.
- Connections: Remember that business deductions directly impact a partner's or S-corp shareholder's basis, are a key component of depreciation calculations, and determine the net income that flows to an individual's Form 1040.
- Final Review: Create a one-page reference sheet of just the numbers. Write down the EBL thresholds for the current year, the start-up cost phase-out range ($50k-$55k), the meal deduction percentage (50%), and the NOL limit (80%). Reviewing this sheet for five minutes before your exam can make a critical difference.
