Following the Supreme Court's decision in South Dakota v. Wayfair (2018), economic nexus for sales tax purposes is established when:
Explanation: Wayfair eliminated the physical presence requirement for sales tax nexus - economic presence (meeting transaction or revenue thresholds) is sufficient. Answer A is correct. Physical presence (B) is no longer required. National revenue (C) is not the nexus standard. Advertising (D) alone does not establish economic nexus.
A state that uses a single sales factor apportionment formula:
Explanation: Single sales factor apportionment uses only the sales ratio, which benefits companies with in-state production (property/payroll) and out-of-state sales by excluding property and payroll from the formula. Answer D is correct. Employee location (A) is a nexus issue. Payroll-only (B) describes a payroll factor formula. Equal allocation (C) ignores the actual formula.
The sales factor in state income tax apportionment is generally calculated as:
Explanation: The sales factor = in-state (state-sourced) sales / total everywhere sales, expressed as a fraction. Answer A is correct. Absolute sales amount (B) is not the factor. AR averages (C) are used in property factor calculations. Customer counts (D) are not the sales factor.
Under the 'market-based sourcing' rule for services, sales are typically sourced to:
Explanation: Market-based sourcing sources service revenue to where the customer receives the benefit - favoring businesses with out-of-state performance that serve in-state customers. Answer C is correct. Cost-of-performance (A) is the traditional alternative rule. Headquarters (B) is not the sourcing standard. Tax rate (D) is not a sourcing rule.
The 'throwback rule' in state apportionment applies when:
Explanation: The throwback rule prevents 'nowhere income' by assigning sales back to the shipping state when the seller lacks nexus in the destination state. Answer D is correct. Year-over-year changes (A) are irrelevant. Nexus everywhere (B) is the opposite situation where throwback doesn't apply. Factor comparisons (C) don't trigger throwback.
A taxpayer has the following data for State Y: property in State Y = 200,000;totalpropertyeverywhere=1,000,000; payroll in State Y = 100,000;totalpayrolleverywhere=500,000; sales in State Y = 300,000;totalsaleseverywhere=1,500,000. Using a three-factor equally weighted formula, State Y's apportionment percentage is:
Explanation: Property: 200K/1M = 20%; Payroll: 100K/500K = 20%; Sales: 300K/1.5M = 20%. Average = (20+20+20)/3 = 20%. Answer A is correct. The sales factor is 20% (300K/1.5M), not 30% (B, C, D are all wrong because sales = 300/1500 = 20%).
Physical presence nexus for income tax purposes can be established by:
Explanation: Physical nexus for income tax can arise from employees, agents, property, or inventory - connections beyond protected solicitation activities under P.L. 86-272. Answer C is correct. Advertising (A), billing customers (B), and bank accounts (D) generally do not create physical nexus.
A state requires combined reporting for unitary businesses. 'Combined reporting' requires:
Explanation: Combined reporting eliminates tax avoidance through intercompany transactions by treating the unitary group as a single entity for apportionment purposes. Answer D is correct. Separate filing (A) allows income shifting combined reporting prevents. Combined reporting is based on unitary income, not consolidated federal income (B). Only parent reporting (C) doesn't capture the unitary concept.
Economic nexus standards for state income tax purposes (separate from sales tax Wayfair thresholds) typically arise when:
Explanation: Many states have enacted economic nexus standards for income tax that set minimum revenue thresholds, creating nexus without physical presence following Wayfair. Answer A is correct. Any customer (B) is too broad. A 10% threshold (C) is not a standard threshold. Business registration (D) creates nexus but is not the economic nexus standard.
A business sells software as a service (SaaS) to customers in multiple states. Under market-based sourcing, the revenue from each SaaS subscription would be sourced to:
Explanation: Market-based sourcing assigns SaaS revenue to where the customer accesses and uses the service - the customer's location. Answer B is correct. Server location (A) is the cost-of-performance approach, not market-based. Development state (C) is not the sourcing rule. Equal allocation (D) is not the standard.
A corporation is determined to be a 'unitary business' with its subsidiaries. The unitary concept requires:
Explanation: The unitary business concept requires evidence of operational integration, central management, and economies of scale - the constitutional and economic basis for combined reporting. Answer A is correct. Ownership percentage (B) is one factor but not the only test. Combined returns are required in combined reporting states (C) but not automatically everywhere. Incorporation state (D) is irrelevant.
A multistate business with nexus in three states uses a double-weighted sales factor formula. In a state that double-weights sales, the apportionment formula is:
Explanation: In a double-weighted sales formula, the sales factor is counted twice and the denominator is increased to 4 to keep the formula summing to 100%. The correct formulation is (Property factor + Payroll factor + Sales factor + Sales factor) / 4, which equals (P + W + 2S) / 4. Answer C is correct. Equal weighting (A) is the traditional three-factor formula, not double-weighted. Answer B incorrectly keeps the denominator at 3 while doubling the sales numerator weight - this would cause the formula to sum to more than 100%. Answer D ignores the payroll factor entirely, leaving an incomplete formula.
A sales transaction is 'sourced' to a state for apportionment purposes when:
Explanation: Sales factor sourcing follows destination rules - sales are assigned to the state where the customer receives the product or the benefit of the service. Answer D is correct. Bank account location (A), salesperson location (B), and invoice origin (C) are not standard sourcing rules.
Which of the following best describes the relationship between federal taxable income and state taxable income for a corporation?
Explanation: State income tax computations typically begin with federal taxable income and adjust for state-specific items - states vary in their conformity to federal law. Answer A is correct. State and federal income often differ (B). GAAP net income is for financial reporting (C). There is a direct relationship - federal TI is the starting point (D).
A state may tax a non-domiciliary corporation's income only to the extent of the income that is:
Explanation: The Constitution (Commerce and Due Process Clauses) requires that state income tax on interstate commerce be fairly apportioned, have nexus, be non-discriminatory, and fairly related to services provided. Answer D is correct. Employee wages (A), customer billing (B), and in-state assets (C) are components of the formula, not the complete constitutional standard.
Which of the following situations would cause a company to lose P.L. 86-272 protection from state income tax?
Explanation: P.L. 86-272 protection is lost when employees perform activities beyond protected solicitation - service, repair, installation, and other non-solicitation activities create nexus. Answer B is correct. Order solicitation (A) is protected. Shipping from outside (C) is the protected activity. Advertising (D) typically does not create income tax nexus.
A taxpayer subject to income tax in multiple states may face 'nowhere income' - income that is not taxed by any state - when:
Explanation: Nowhere income arises when sales go to nexus-lacking destination states without a throwback rule - the sales are excluded from the numerator of all states and are therefore not apportioned to any state. Answer B is correct. Treasury interest (A) has specific exclusion rules. No-tax states (C) don't create nowhere income. Capital gains (D) are subject to allocation rules.
The property factor in state apportionment is generally computed using:
Explanation: The property factor uses the average of beginning and ending year values (typically cost or GAAP basis) of owned and rented tangible property (rented property is typically valued at 8x annual rent). Answer C is correct. FMV (A) is generally not used. Book value alone (B) ignores the averaging and rental property. Assessed value (D) is not the apportionment standard.
The 'throwout rule' (used by some states) differs from the throwback rule in that:
Explanation: The throwout rule removes 'nowhere sales' from the sales denominator (rather than adding them to the originating state's numerator), which can increase apportionment percentages for states where the taxpayer has nexus. Answer B is correct. Throwout doesn't throw back to origin state (A). Both rules apply to various business types (C). Throwout affects the denominator, not direct allocation (D).
Public Law 86-272 (P.L. 86-272) provides protection from state income tax when a business:
Explanation: P.L. 86-272 protects companies from state income tax when their only in-state activity is soliciting orders for tangible personal property shipped from outside the state. Answer C is correct. Incorporation state (A) doesn't provide P.L. 86-272 protection. No dollar threshold exists (B). Employees may be present for solicitation (D).
