Accounting changes and error corrections
Accounting changes and error corrections CPA exam FAR items are three events with three treatments, and the whole group is deciding which one you are looking at. A change in accounting principle is applied retrospectively. A change in estimate is applied prospectively, with no restatement of anything. An error is corrected by restating prior periods. A change in depreciation method is the exam’s favourite fact pattern precisely because it looks like the first and is treated as the second.

What the Blueprint asks for here
At this group the Blueprint expects a candidate to identify a change in accounting principle, a change in accounting estimate, a change in reporting entity and an error in previously issued financial statements, to determine the reporting treatment each requires, and to calculate the amounts reported as a result.

Accounting changes and error corrections CPA exam FAR: three treatments
Why this group is worth its weight
This group is examined at the Analysis level and turns on a classification that is easy to state and hard to apply under time pressure. It also compounds: a candidate who misclassifies the event gets every subsequent number wrong, so items in this group tend to be all-or-nothing rather than partially recoverable.
The three treatments, and what each one touches
Retrospective application restates prior periods presented as if the new principle had always been used, with the cumulative effect on periods before the earliest one presented adjusted into opening retained earnings. Prospective application changes nothing already reported: the new estimate is applied from the date of change forward, over the remaining carrying amount and the remaining life. Restatement corrects an error by adjusting the prior-period statements themselves and opening retained earnings, and it comes with disclosure that an error occurred.
The change that is classified by rule, not by reasoning
A change in depreciation method looks like a change in principle — straight-line to double-declining is a change in method — and is treated as a change in accounting estimate, on the reasoning that the method is inseparable from the estimate of how the asset’s benefits are consumed. That makes it prospective. Candidates who reason from the word “method” restate prior years and produce a defensible-looking wrong answer, which is why the exam keeps asking it.
Doing the prospective arithmetic
Prospective means you never touch what has already been recorded. Take the carrying amount at the date of change, subtract any residual value, and spread the result over the remaining life — where remaining life is the revised total life less the years already elapsed. The two errors that follow are dividing by the revised total life instead of the remaining life, and forgetting that the years already depreciated still count against the revised total.
The standard this group is examined on is published by the standard setter: FASB Accounting Standards Codification. The Blueprint coordinates and weight ranges above come from the AICPA Blueprints. What is ours, and labelled as ours, is the reading, the practice item and the misconception tags.
A practice item
our own practice item Written by us against the public Blueprint. It is not an AICPA question and it is not taken from any review course.
A company bought equipment on 1 January Year 1 for $500,000 with no residual value and depreciated it straight-line over an estimated useful life of 10 years. On 1 January Year 4, before recording any Year 4 depreciation, the company revises its estimate of the equipment’s total useful life from 10 years to 8 years. Residual value is still estimated at zero.
What is depreciation expense for Year 4?
| A | $50,000 | |
| B | $62,500 | |
| C | $70,000 | correct |
| D | $87,500 |
The rule
A change in accounting estimate is accounted for prospectively in the period of change and future periods; prior periods are not restated and no cumulative catch-up adjustment is recorded. Depreciation after the change is the carrying amount at the date of change, less residual value, allocated over the remaining useful life. A change in depreciation method is treated as a change in estimate, not as a change in accounting principle.
The arithmetic
Three years at $500,000 / 10 = $50,000 gives accumulated depreciation of $150,000 and a carrying amount of $350,000 at 1 January Year 4. The revised total life is 8 years and 3 have elapsed, leaving 5. $350,000 / 5 = $70,000 for Year 4 and each of the four years after it. Nothing already recorded is changed.
What we would ask you first
This is the part of the product that is hard to show without an account, so here it is directly: for each wrong option above, the opening question our tutor asks — before any explanation — targeting the specific mistake that option represents. Choosing A ($50,000) and choosing D ($87,500) are different errors and deserve different first questions.
If you chose A — change_ignored
“That is the figure the company was already recording. The estimate changed on 1 January Year 4 — what is a change in estimate supposed to do from that date forward?”
If you chose B — revised_life_applied_to_original_cost
“You divided the original $500,000 by the revised eight-year life. That treats the change as though it had always applied. Which of the three treatments would do that, and is this event one of them?”
If you chose D — remaining_life_miscounted
“Your carrying amount is right and your remaining life is not. The asset has been depreciated for three years against a revised total of eight. How many years of that total are left?”
To be precise about what happens next: the exchange is a rate limit, not a gate. Answering well gets you to the full worked explanation in three or four exchanges; answering badly still gets you there. And if you would rather skip it, asking three times gets you the walkthrough.
Common questions
Is a change in depreciation method retrospective or prospective?
Prospective. A change in depreciation method is treated as a change in accounting estimate effected by a change in principle, because the method is inseparable from the estimate of how the asset's benefits are consumed. Prior periods are not restated; the carrying amount at the date of change is spread over the remaining life.
What is the difference between a change in estimate and an error?
A change in estimate reflects new information about the future and is applied prospectively with no restatement. An error is a mistake in previously issued financial statements — a mathematical mistake, a misapplication of a principle, or an oversight of facts that existed at the time — and is corrected by restating the prior periods presented.
Misconception tags in this group
These are the labels our diagnosis attaches when a wrong answer matches a known pattern. They are worth reading even if you never use the product — naming your own error is most of the work.
change_ignored— Continuing with the original schedule after an estimate has been revised.revised_life_applied_to_original_cost— Applying the revised life to the original cost, which is retrospective treatment of a prospective change.remaining_life_miscounted— Spreading the carrying amount over the wrong number of remaining years.method_change_treated_as_principle— Restating prior periods for a change in depreciation method, which is treated as a change in estimate.error_treated_as_estimate— Adjusting an error prospectively instead of restating prior periods.
