Everyone is talking about the reweighted content outline. The reweighting is the smaller change. The one that actually rewrites answer keys is the law-year cutover happening on the same date — and it is the reason a study guide bought last year can be confidently, fluently wrong.
On September 5, 2026, the Certified Payroll Professional exam adopts a revised content outline and rolls its knowledge cutoff forward a full year at the same moment.
The outline change shifts how many questions come from each of the seven content areas. It matters for how you allocate study hours. The law-year change moves the tested body of federal law from January 1, 2025 to January 1, 2026. That one matters for whether your answers are right.
They are independent of each other. A candidate sitting on September 3 gets the old weightings and 2025 law. A candidate sitting on September 8 gets the new weightings and 2026 law. There is no transition period and no partial credit for having studied the wrong year.
PayrollOrg publishes the CPP content outline as seven areas with a percentage weight each. The area names barely move. The weights do. Here is the outline in effect through September 4, 2026 next to the one that takes effect September 5, 2026.
| Content area | Through Sep 4, 2026 | From Sep 5, 2026 | Change |
|---|---|---|---|
| Core Payroll Concepts | 24% | 24% | — |
| Calculation of the Paycheck | 20% | 22% | +2 |
| Compliance/Research and Resources | 16% | 14% | −2 |
| Payroll Process and Supporting Systems | 12% | 14% | +2 |
| Payroll Administration and Management | 10% | 10% | — |
| Audits | 9% | 8% | −1 |
| Accounting | 9% | 8% | −1 |
| TOTAL — 100% BOTH COLUMNS | |||
A note on naming: in the older outline the fourth area is titled Payroll Process and Supporting Systems and Administration, which sat awkwardly beside a separate Payroll Administration and Management area. The revised outline cleans that up. Same territory, clearer line between the systems that run payroll and the people who manage it.
The net movement is four percentage points, and it moves in one direction: toward the work of producing a paycheck and the systems that produce it, away from research, audit and accounting theory. Calculation of the Paycheck and Payroll Process together go from 32% to 36% of the exam. Audits plus Accounting together drop from 18% to 16%.
On a 190-question exam of which 25 are unscored pretest items — so roughly 165 scored — two percentage points is about three questions. Individually small. Cumulatively, it tells you where the exam's centre of gravity moved, and if you are budgeting sixty hours of study you should move a few of them with it.
Nobody fails the CPP because they studied Accounting to 9% instead of 8%. The outline change is worth knowing and worth a modest reallocation of hours. It is not the thing that will surprise you in the exam room. The next section is.
The CPP does not test the law as it stands on the day you sit. It tests the law as it stood on a fixed January 1 cutoff, and that cutoff is pinned to the administration period, not to the calendar. Legislation enacted mid-year is not tested in that year's exam.
| If you test… | The exam tests federal law as of… |
|---|---|
| Sep 6, 2025 – Sep 4, 2026 | January 1, 2025 |
| Sep 5, 2026 – Sep 3, 2027 | January 1, 2026 |
Read those two rows again with a date in mind. The entire Fall 2026 window (September 5 – October 3, 2026) and the entire Spring 2027 window (January 4 – April 17, 2027) sit on the 2026 side of that line. If you are testing in either of them, every indexed figure you memorised from 2025-vintage material is a wrong answer that will look completely reasonable to you.
This is not exhaustive — it is the set most likely to appear in a calculation question, where a stale number produces a confidently wrong dollar amount rather than an obvious blank.
| Item | 2025 (tested through Sep 4, 2026) | 2026 (tested from Sep 5, 2026) |
|---|---|---|
| Social Security taxable wage base | $176,100 | $184,500 |
| 401(k)/403(b) elective deferral limit | $23,500 | $24,500 |
| Age-50 catch-up contribution | $7,500 | $8,000 |
| Age 60–63 “super” catch-up | $11,250 | $11,250 |
| §129 dependent care assistance exclusion | $5,000 | $7,500 |
| Social Security / Medicare rates | 6.2% / 1.45% | 6.2% / 1.45% |
The rates are unchanged, which is exactly why the wage base is dangerous: the method you practised still works perfectly, applied to a ceiling that no longer exists. An OASDI question built on $176,100 and answered with $176,100 is the cleanest way to lose a mark you knew how to earn.
Indexed limits are announced annually and occasionally revised. Every figure above is worth confirming against the IRS notice or publication it comes from before it goes on a flashcard — and worth confirming again if you are reading this months after it was written. The mechanism is stable; the numbers are not.
The One Big Beautiful Bill Act is the substantive reason the 2026 law year is not simply the 2025 law year with bigger numbers. Several of its payroll-facing provisions first apply to a full payroll year in 2026, which puts them squarely inside the body of law tested from September 5, 2026 onward — and entirely outside any material written to January 1, 2025.
Employees in customarily tipped occupations may deduct qualified tips, subject to an annual cap (reported at up to $25,000, with a higher joint figure) and phased down at higher adjusted gross income. The list of qualifying occupations is defined by Treasury guidance.
Employees may deduct qualified overtime compensation, capped annually (reported at up to $12,500, doubled for joint filers). The critical detail for a payroll professional is the definition: it reaches only the premium portion of overtime required under the FLSA — the half in “time and a half,” not the whole overtime payment, and not contractual overtime the FLSA does not require. Expect that distinction to be tested, because it is precisely the kind of thing the CPP likes to test.
The exclusion for employer-provided dependent care assistance moves from $5,000 to $7,500 ($3,750 for married filing separately), a limit that had been frozen for decades. Anything you memorised as “$5,000, or $2,500 if MFS” is now wrong for the tested year — and it is a stock CPP question.
Beginning with 2026 reporting, qualified tips and qualified overtime compensation are reported separately in Box 12 of Form W-2, using code TP for qualified tips and code TT for qualified overtime compensation. For 2025 the separate reporting was encouraged rather than required, with transition relief.
These are deductions the employee claims on their own return, not payroll exclusions. Tips and overtime remain wages. They are still subject to federal income tax withholding. They are still subject to Social Security and Medicare. Nothing about the gross-to-net calculation changes.
What changes for payroll is tracking and reporting: you now have to identify qualified tips and isolate the FLSA premium portion of overtime so they can be reported separately. An exam question that offers you “reduce federal income tax withholding on the overtime premium” is offering you the trap.
| Window | Registration | Testing | Law year |
|---|---|---|---|
| Fall 2026 | Jul 1 – Oct 2, 2026 | Sep 5 – Oct 3, 2026 | Jan 1, 2026 |
| Spring 2027 | Nov 9, 2026 – Apr 16, 2027 | Jan 4 – Apr 17, 2027 | Jan 1, 2026 |
Note the shape of that: registration for Fall 2026 closes October 2, one day before testing ends. Registration is not the same deadline as scheduling a seat — you register with PayrollOrg, then reserve an appointment through Pearson VUE, and popular centres fill from the front of the window. Treat the useful deadline as several weeks earlier than the published one.
The CPP Candidate Handbook distributed through Pearson VUE lists the exam fee as not published on PayrollOrg’s public certification page. PayrollOrg states only that members save 30% off the CPP exam fee; third-party sites quote figures between roughly $380 and $635 and contradict one another. Confirm the current fee on payroll.org before you register — including against this page. Fees are restated with each handbook edition and third-party summaries frequently quote stale or slightly different figures, so confirm the current price on payroll.org before you budget. The membership spread is large enough that joining PayrollOrg is worth pricing out as part of the same decision.
Exam format, per the same handbook: 190 multiple-choice questions, of which 25 are unscored pretest items, in a four-hour appointment.
Partly. Keep it for the mechanics. Do not trust a single number in it.
This is the most common question about the September 5 change and it deserves a real answer rather than a scare. Here is the split.
Practically: a 2025 guide is still a decent textbook and a bad answer key. If you are working from one, keep it open for the “why,” and pull every number from a current source — IRS Publication 15 for the tested year, the relevant IRS annual limits notice, and the current edition of PayrollOrg's own reference.
No evidence of that, and the passing standard is set against the exam, not against a fixed score. What it makes is different, in a way that penalises stale study material more than it penalises weak candidates.
January 1, 2026 — the same as Fall 2026. The administration period runs September 5, 2026 through September 3, 2027, so both windows sit inside it.
Only if you are genuinely close to ready. Sitting underprepared to dodge a two-point weighting shift and a set of figure updates is a bad trade — you pay the full exam fee either way. But if you have been studying 2025 material all year and you are ready now, testing under the law year you actually studied is worth something real.
No. They are deductions the employee takes on their individual return. The wages remain wages for income tax withholding and for Social Security and Medicare. What changes is that payroll must now identify and separately report those amounts.
PayrollOrg publishes the content outline and the knowledge-cutoff dates; Pearson VUE publishes the Candidate Handbook with fees, format and testing policy. Both are linked below. Where this page and those disagree, they are right.
We rebuilt our question bank against the September 5, 2026 outline and to federal law as of January 1, 2026, because we had to — the alternative was shipping the same stale figures this page warns about. So there is an obvious plug here, and here it is, stated once.
If you want to know which of the seven areas is actually your weak one before you spend money on anything, the 20-question diagnostic is free. No card, and it gives you a per-area breakdown you can plan around. If it tells you that you are fine, you are fine — that is a useful result too.
The full bank is 400 questions for $39, once, with a written explanation on every one and a 30-day refund if it is not useful. It is not a substitute for PayrollOrg's own materials and does not pretend to be. It is drill.
