QUESTION 1
In 2026, what is the standard deduction amount for a single taxpayer under
age 65?
A) $12,500
B) $13,500
C) $14,000
D) $13,850
,E) $15,000
CORRECT ANSWER: D) $13,850
EXPERT RATIONALE: The standard deduction for single taxpayers in 2026 is
$13,850. This amount is adjusted annually for inflation. The IRS announced this
figure as part of the 2026 inflation adjustments. Single taxpayers who are age 65 or
older, or blind, receive an additional standard deduction amount. This is a
foundational tax concept that every tax specialist must understand.
QUESTION 2
Which of the following represents the tax treatment of qualified dividends for
a taxpayer in the 37% ordinary income tax bracket in 2026?
A) Taxed at ordinary income tax rates
B) Taxed at a maximum rate of 20%
C) Completely tax-exempt
D) Taxed at the net investment income tax rate of 3.8%
E) Taxed at a capital gains rate of 25%
CORRECT ANSWER: B) Taxed at a maximum rate of 20%
EXPERT RATIONALE: Qualified dividends receive preferential capital gains
treatment and are taxed at a maximum federal rate of 20% even for taxpayers in
the highest ordinary income bracket. This preferential rate was created to
encourage long-term investment. Non-qualified dividends, however, are taxed at
ordinary income tax rates. Net Investment Income Tax of 3.8% may apply in
addition to the capital gains rate for higher-income taxpayers. Understanding the
distinction between qualified and non-qualified dividends is critical for tax planning.
QUESTION 3
What is the primary purpose of Form 1040-ES (Estimated Tax for Individuals)?
,A) To claim the Earned Income Credit
B) To make quarterly estimated tax payments on income not subject to withholding
C) To file extensions for income tax returns
D) To report rental property income
E) To claim self-employment tax deductions
CORRECT ANSWER: B) To make quarterly estimated tax payments on
income not subject to withholding
EXPERT RATIONALE: Form 1040-ES is used by individuals to calculate and pay
quarterly estimated tax payments on income that is not subject to withholding,
such as self-employment income, rental income, and capital gains. Estimated taxes
are typically required when an individual expects to owe $1,000 or more in taxes.
The payments are made quarterly on specific due dates: April 15, June 15,
September 15, and January 15. Failing to pay estimated taxes can result in
underpayment penalties and interest.
QUESTION 4
A taxpayer has a long-term capital loss of $8,000 in 2026. How much of this
loss can be deducted against ordinary income in the current year?
A) The entire $8,000
B) $3,000
C) $5,000
D) $2,000
E) None, it must be carried back
CORRECT ANSWER: B) $3,000
EXPERT RATIONALE: Capital losses can be deducted against capital gains, and if
capital losses exceed capital gains, up to $3,000 of the net capital loss can be
deducted against ordinary income in the current year. Any excess capital loss
, beyond the $3,000 annual limit is carried forward indefinitely to future years. This
limit applies whether the loss is long-term or short-term. Capital losses cannot be
carried back. The $3,000 deduction limitation is a fundamental tax principle used to
prevent significant tax benefits from concentrated losses.
QUESTION 5
Which expense is NOT deductible as a business expense for a self-employed
individual?
A) Office supplies and equipment
B) Professional dues and memberships
C) Personal commuting expenses to the office
D) Home office expenses if properly allocated
E) Continuing education related to the business
CORRECT ANSWER: C) Personal commuting expenses to the office
EXPERT RATIONALE: Personal commuting expenses are non-deductible personal
expenses under IRC Section 262. Commuting refers to travel between home and
the principal place of business, even if that office is a home office. However, travel
expenses from one business location to another are deductible, as are temporary
work location expenses. The distinction between personal commuting and business
travel is critical. All other listed expenses are generally deductible if ordinary and
necessary for the business and if they have a legitimate business purpose.
QUESTION 6

(Retirement Savings Contributions Credit) for a single taxpayer in 2026?
