Common Mistakes on the CPA FAR Exam and How to Avoid Them

Why Candidates Fail FAR

FAR has historically had one of the lower pass rates among CPA exam sections, and the reasons are consistent. Candidates make predictable mistakes that cost them points. Some errors are conceptual misunderstandings, while others are careless calculation errors or poor time management choices. Recognizing these common pitfalls before exam day lets you build habits that prevent them.

Conceptual Mistakes

Confusing Modified Accrual and Full Accrual Basis

One of the most common FAR mistakes involves mixing up the rules for governmental fund accounting (modified accrual) with government-wide financial statements (full accrual). Under modified accrual, revenues are recognized when measurable and available, and expenditures are recognized when the fund liability is incurred. Under full accrual, revenues are recognized when earned and expenses when incurred. Candidates frequently apply the wrong basis to the wrong set of statements, especially when dealing with capital assets and long-term liabilities that appear on government-wide statements but not on fund financial statements.

Misapplying Lease Classification Criteria

ASC 842 uses different classification criteria for lessees and lessors, and candidates often mix them up. For lessees, a lease is classified as a finance lease if any one of five criteria is met: transfer of ownership, purchase option reasonably certain to be exercised, lease term is a major part of economic life, present value of payments is substantially all of fair value, or the asset is specialized. Candidates sometimes forget that lessees have only two classifications (finance and operating) while lessors have three (sales-type, direct financing, and operating).

Errors in Revenue Recognition Timing

Under ASC 606, candidates frequently struggle with determining whether revenue should be recognized over time or at a point in time. The three criteria for over-time recognition are specific, and all three must be evaluated. A common mistake is assuming that any service contract satisfies the "simultaneous receipt and consumption" criterion when it may not. Another frequent error is failing to identify multiple performance obligations in a bundled contract, leading to incorrect allocation of the transaction price.

Forgetting to Eliminate Intercompany Transactions

In consolidation problems, candidates sometimes forget to eliminate all intercompany transactions, including upstream and downstream inventory sales, intercompany loans, and intercompany service fees. The direction of the sale matters for allocating the elimination between the parent and the noncontrolling interest. Downstream sales (parent to subsidiary) are eliminated entirely against the parent, while upstream sales (subsidiary to parent) are allocated between the parent and noncontrolling interest.

Calculation Mistakes

Effective Interest Method Errors

When amortizing bond premiums or discounts, candidates sometimes multiply the wrong rate by the wrong amount. The effective interest method requires multiplying the carrying amount of the bond by the market rate to determine interest expense, then comparing that to the cash interest paid (face value times stated rate). The difference is the amortization. A common error is using the stated rate on the carrying amount or the market rate on the face value.

Pension Calculation Mistakes

Net periodic pension cost has multiple components, and candidates frequently miscalculate one or more of them. The most common errors are using the wrong rate for the expected return on plan assets (use the expected rate, not the actual return), miscalculating the amortization of prior service cost, and confusing the projected benefit obligation with the accumulated benefit obligation when determining the funded status.

Deferred Tax Miscalculations

Candidates often struggle with determining whether a temporary difference creates a deferred tax asset or liability. The key is whether the difference will result in future taxable amounts (creating a liability) or future deductible amounts (creating an asset). Prepaid expenses, for example, are deductible when paid for tax purposes but expensed over time for book purposes, creating a deferred tax asset. Candidates sometimes reverse the direction.

Strategic Mistakes

Spending Too Much Time on Government Accounting

Ironically, while skipping government accounting is a common mistake, so is spending too much time on a single government accounting question. Government questions can involve complex fund accounting scenarios with multiple transactions. Candidates who spend 10 minutes on one government multiple-choice question are sacrificing time for three or four other questions. Set a time limit and move on.

Ignoring the Research Task

FAR simulations include a research task that asks you to find the relevant authoritative guidance. Some candidates skip this task or spend very little time on it because they find the codification search tool unfamiliar. Practice using the FASB Codification search before exam day. The research question is often one of the most straightforward simulation tasks if you know how to navigate the tool.

Not Reading Simulation Instructions Carefully

FAR simulations often provide specific instructions about what to include or exclude, rounding conventions, or which financial statement period to use. Candidates who skim these instructions and jump into calculations often produce technically correct answers to the wrong question. Read every instruction word by word before beginning your work.

How to Build Better Habits

Review your practice exam results with a focus on error patterns, not just overall scores. Categorize each mistake as conceptual, calculation, or strategic, and address each type differently. Conceptual mistakes require re-studying the topic. Calculation mistakes require more practice problems. Strategic mistakes require adjusting your exam-day approach. By identifying and correcting your personal error patterns before exam day, you eliminate the most likely sources of lost points.
