All questions
Question 1
A C corporation offers which of the following tax advantages over pass-through entities for certain high-income business owners?
- All C corporation income avoids double taxation since dividends are deductible.
- C corporations allow unlimited loss deductions at the owner level.
- The 21% flat corporate rate may be lower than the individual rate on the same income, and C corporations can retain earnings for growth at the corporate rate before triggering individual-level tax. (correct answer)
- C corporations are not subject to the net investment income tax.
Explanation: The 21% corporate rate can be beneficial when the owner's individual rate would be higher. Answer C is correct.
Question 2
An LLC with two members that has not made a check-the-box election is treated for federal income tax purposes as:
- A C corporation by default.
- A partnership by default - the default classification for a multi-member LLC is a partnership, subject to all partnership tax rules. (correct answer)
- An S corporation by default.
- A disregarded entity by default.
Explanation: Multi-member LLCs are classified as partnerships by default under check-the-box regulations. Answer B is correct.
Question 3
A single-member LLC that has not made a check-the-box election is treated for federal income tax purposes as:
- A C corporation.
- An S corporation.
- A partnership with the owner as the sole partner.
- A disregarded entity - the LLC is ignored for tax purposes and all income and expenses are reported directly on the owner's individual return. (correct answer)
Explanation: A single-member LLC is a disregarded entity by default - treated as a sole proprietorship. Answer D is correct.
Question 4
Which entity structure provides the most flexibility in allocating income, losses, and distributions among owners?
- A partnership (including multi-member LLC taxed as a partnership) - special allocations with substantial economic effect are permitted. (correct answer)
- An S corporation - shareholders can agree to allocate income differently than ownership percentages.
- A C corporation - corporations have maximum flexibility in setting dividend amounts.
- A sole proprietorship - the owner has complete control over income allocation.
Explanation: Partnerships allow special allocations as long as they meet the substantial economic effect test. Answer A is correct.
Question 5
A business owner wants to provide health insurance to themselves and deduct the premiums. Which entity structure provides the most favorable treatment?
- S corporation - the shareholder-employee can deduct 100% of premiums without any limitation.
- Partnership - partners can deduct health insurance premiums as a guaranteed payment.
- C corporation - the corporation can deduct premiums as a business expense, and the shareholder-employee pays no income tax on the premium benefit, making it fully tax-advantaged. (correct answer)
- Sole proprietorship - the self-employed person can deduct 100% of premiums above the line.
Explanation: A C corporation can deduct health insurance premiums and the employee-shareholder pays no tax on the benefit. Answer C is correct.
Question 6
The qualified business income (QBI) deduction under Section 199A is available to:
- C corporations and their shareholders.
- All taxpayers who own a business of any structure.
- Only S corporation shareholders.
- Owners of pass-through businesses (sole proprietorships, partnerships, S corporations, and certain trusts/estates) - not C corporations - subject to income limitations and restrictions for SSTBs. (correct answer)
Explanation: The QBI deduction is available to pass-through entity owners, not C corporations. Answer D is correct.
Question 7
A business anticipates significant losses in its early years. Which entity structure best allows the owner to use those losses to offset other income?
- C corporation - losses flow through to shareholders immediately.
- Pass-through entity (S corporation, partnership, or sole proprietorship) - losses flow through to the owner's individual return and can offset other income, subject to basis, at-risk, and passive activity limitations. (correct answer)
- C corporation - the corporation can carry losses back to generate refunds.
- Any entity structure - all business losses may be used immediately.
Explanation: Pass-through entities allow loss flow-through to owners for potential use against other income. C corp losses stay at the corporate level. Answer B is correct.
Question 8
An S corporation has a significant advantage over a partnership for owners who want to limit payroll tax exposure because:
- S corporation income allocated to shareholders beyond reasonable wages is not subject to FICA - unlike partnerships where active general partners may owe SE tax on their distributive share. (correct answer)
- S corporation shareholders are exempt from all employment taxes.
- S corporations do not have to pay any payroll taxes.
- Partnerships require all income to be subject to self-employment tax.
Explanation: Active S corp shareholders pay FICA only on wages; distributions above wages avoid payroll taxes. General partners typically pay SE tax on their distributive share. Answer A is correct.
Question 9
When comparing entity structures for estate planning purposes, which feature makes the partnership or LLC particularly useful?
- Partnership interests cannot be transferred to family members without triggering gain recognition.
- Partnerships are exempt from the estate tax.
- Family limited partnerships (FLPs) allow transfer of interests to heirs at discounted values (lack of control and marketability discounts), potentially reducing estate and gift taxes. (correct answer)
- Partnerships automatically receive a step-up in basis on all assets when a partner dies.
Explanation: FLPs allow valuation discounts on transferred interests, reducing taxable value for estate and gift tax purposes. Answer C is correct.
Question 10
A business owner converting from a C corporation to an S corporation may face:
- No tax consequences since conversions between entity types are always tax-free.
- Immediate taxation on all of the C corporation's retained earnings.
- Taxation on the fair market value of all assets at the time of conversion.
- The built-in gains (BIG) tax under Section 1374 - if the S corporation sells appreciated assets within 5 years after conversion, the gain attributable to pre-conversion appreciation is taxed at the 21% corporate rate. (correct answer)
Explanation: The built-in gains tax applies for 5 years on gains from pre-conversion appreciation. Answer D is correct.
Question 11
A real estate investment company wants to raise capital from multiple investors while avoiding double taxation and providing liability protection. The most common structure is:
- A limited partnership or LLC taxed as a partnership - providing pass-through taxation, limited liability for passive investors, and flexibility in allocating income and losses. (correct answer)
- A C corporation to allow for stock issuance to investors.
- An S corporation to minimize FICA taxes on distributions.
- A real estate investment trust (REIT) for all real estate investments.
Explanation: LPs and LLCs taxed as partnerships are ideal for real estate - pass-through taxation, limited liability, and special allocation flexibility. Answer A is correct.
Question 12
An individual who converts their sole proprietorship to a corporation contributes all assets and liabilities. Under Section 351, the transfer is:
- Always taxable since the individual is transferring assets to a separate entity.
- Taxable only on the gain attributable to appreciated property.
- Tax-free if the transferors receive stock and control (at least 80%) of the corporation immediately after the transfer - with the corporation taking a carryover basis in the assets. (correct answer)
- Tax-free only if no liabilities are transferred.
Explanation: Section 351 provides nonrecognition for property contributions to a controlled corporation. Answer C is correct.
Question 13
A business owner considering entity choice should evaluate self-employment tax implications. Which entity structure has the lowest SE tax burden for an active owner who earns $300,000?
- Sole proprietorship - SE tax on $300,000 net income.
- Partnership with general partner status - SE tax on $300,000 distributive share.
- Partnership with limited partner status - limited partners generally exempt from SE tax.
- S corporation paying 100,000inwagesand200,000 in distributions - FICA applies only to the 100,000inwages,withdistributionsavoidingpayrolltax;theactualsavingsdependonwage−baselimits(SocialSecuritycapsat 168,600) and Medicare rates. (correct answer)
Explanation: An S corporation with reasonable wages and high distributions minimizes payroll taxes because FICA applies only to wages, not to distributions. At 300,000totalwith100,000 in wages, the S corp avoids payroll tax on the 200,000distribution.Theactualtaxsavingsarenotaflat15.3200,000 - they depend on how much of the Social Security wage base (168,600for2024)wascoveredbywages,andontheMedicarerates(2.9200,000). Answer D is correct. Sole proprietorship (A) and general partnership (B) subject all net income to SE tax. Limited partnership (C) may reduce SE tax but lacks the wage-and-distribution structure and operational flexibility of an S corp.
Question 14
A business owner who qualifies for the Section 199A QBI deduction maximizes the deduction under which entity structure?
- Any pass-through structure (sole proprietorship, partnership, S corporation) - as long as the owner is not a high-income owner of a specified service trade or business, the 20% QBI deduction applies to all qualifying pass-through income. (correct answer)
- Only S corporations since partnerships lack QBI eligibility.
- C corporations - the QBI deduction applies to C corporation dividends.
- Only sole proprietorships - partnerships and S corps are excluded.
Explanation: The QBI deduction applies equally to all qualifying pass-through structures. Answer A is correct.
Question 15
A professional service provider (attorney, physician, consultant) considering entity structure should be aware that:
- Professional service businesses always qualify for the QBI deduction.
- Professional service businesses cannot operate as pass-through entities.
- High-income professionals in specified service trades or businesses (SSTBs) lose the Section 199A QBI deduction above the applicable income thresholds - making C corporation structure potentially more attractive when the QBI deduction is unavailable. (correct answer)
- Professional service businesses have unlimited access to the 20% QBI deduction.
Explanation: SSTB owners above income thresholds lose the QBI deduction - at that point, the C corp's 21% rate may be more attractive. Answer C is correct.
Question 16
An investor purchases a 30% interest in an LLC taxed as a partnership for 100,000.TheLLChas500,000 of nonrecourse debt. What is the investor's initial outside basis?
- $100,000 - the amount invested only.
- $150,000 - the investment plus 30% of the nonrecourse debt.
- $500,000 - the full amount of partnership debt.
- 250,000−the100,000 investment plus 150,000(30500,000 nonrecourse debt share), since partnership liabilities increase partners' outside basis. (correct answer)
Explanation: Outside basis includes cash invested plus the partner's share of partnership liabilities: 100,000+(30500,000) = $250,000. Answer D is correct.
Question 17
A business owner with significant business losses wants to use those losses to offset their W-2 income from a separate job. Which entity structure best enables this?
- C corporation - losses flow through to offset the owner's other income.
- Pass-through entity where the owner materially participates - losses flow through to the owner's return and can offset non-passive income like W-2 wages, subject to basis, at-risk, and passive activity rules. (correct answer)
- Any entity structure - all business losses offset W-2 income.
- S corporation - S corp losses always offset W-2 income without limitation.
Explanation: Pass-through entities where the owner materially participates allow losses to offset W-2 income subject to applicable limitations. Answer B is correct.
Question 18
For a business expecting to sell appreciated assets in the next 3-5 years, which entity structure minimizes the total tax cost on exit?
- C corporation - corporate gain taxed at 21%, then no further tax on distribution.
- S corporation - gain taxed once at the shareholder level avoiding corporate-level tax.
- Depends on the specific facts - an S corporation avoids the built-in gains tax if assets are held more than 5 years after conversion; a partnership allows capital gain treatment; a C corp creates double taxation on asset sales. (correct answer)
- C corporation always provides the lowest exit tax.
Explanation: The optimal exit structure depends on holding period, asset type, and current vs. future rates. Generally, pass-through entities avoid double taxation on exit. Answer C is correct.
Question 19
A business owner who wants to provide significant retirement plan contributions should consider which entity structure?
- Sole proprietorship - sole proprietors cannot establish retirement plans.
- S corporation - S corps have lower retirement plan contribution limits.
- C corporation - C corps provide the largest retirement plan contributions.
- Any entity structure can establish retirement plans (SEP-IRA, SIMPLE IRA, 401(k), defined benefit) - the key is net earned income or compensation, not entity type. (correct answer)
Explanation: Retirement plan options are available across all entity structures. The contribution limits depend on compensation, not entity type. Answer D is correct.
Question 20
A business owner comparing a C corporation to an S corporation should understand that the key difference in exit strategy is:
- S corporations cannot be sold since they must remain closely held.
- A C corporation asset sale results in double taxation (corporate gain + dividend/capital gain on distribution), while an S corporation asset sale results in a single level of tax passed through directly to shareholders. (correct answer)
- C corporations may always use Section 1031 exchanges while S corporations may not.
- S corporations must distribute all proceeds immediately upon an asset sale.
Explanation: The double taxation disadvantage of C corporations in asset sales is a primary reason sellers prefer S corporation status or stock sales. Answer B is correct.
