| If you own an S-Corp, your compensation decision — how much you pay yourself as a W-2 salary versus how much you take as a distribution — is one of the most consequential tax and financial choices you make each year. The IRS requires S-Corp shareholder-employees to pay themselves a "reasonable compensation" before taking distributions, and getting that balance wrong can trigger audits, payroll tax penalties, or an unnecessarily large tax bill. A year-end check of your salary, distributions, and estimated tax payments is the most reliable way to protect yourself and finish the year on solid footing. |
For many S-Corp owners, the year-end rush focuses on one thing: minimizing the tax bill. But before you make any moves, there is a more important question to answer. Are your salary and distribution decisions actually structured the way the IRS expects — and are your estimated tax payments keeping pace with what you actually owe?
This is not a compliance exercise. It is a planning opportunity. The choices you make in the final months of your fiscal year can meaningfully affect your payroll tax exposure, your self-employment and income tax liabilities, and your ability to avoid underpayment penalties. They also lay the groundwork for the following year.
Business Advisory and Accounting Partners powered by Harness works with S-Corp owners year-round to make sure these decisions are coordinated — not scrambled together in December when options are limited and the pressure is high.
The fundamental tax advantage of the S-Corp structure is that business income passed through to shareholders is generally not subject to self-employment tax — but only the portion taken as a distribution. The portion paid as W-2 wages is subject to payroll taxes, including both the employer and employee share of Social Security and Medicare taxes. That distinction is why the salary-versus-distribution split is worth careful attention.
The IRS is aware that S-Corp owners are motivated to minimize their W-2 wages in order to reduce payroll tax exposure. That is precisely why the agency has long maintained that shareholder-employees must receive "reasonable compensation" for the services they provide to the corporation. According to IRS guidance and court precedent, reasonable compensation is generally defined as what a similarly qualified individual would be paid in the open market for the same services. It is not whatever number is most convenient at tax time.
The AICPA and tax practitioners frequently point to IRS Publication 15-A and decades of Tax Court cases as the basis for evaluating reasonable compensation. The IRS has identified S-Corp compensation as a listed compliance area, meaning it receives ongoing scrutiny through examination campaigns. A salary that is unreasonably low relative to business income is one of the cleaner audit triggers in the small business space.
On the other side, some owners overcorrect — paying a salary that is higher than necessary, which increases payroll tax costs and reduces the cash flow advantage the S-Corp structure is meant to provide. Year-end is the moment to check whether your current trajectory is calibrated correctly.
Reasonable compensation is not a single number — it is a conclusion based on facts and circumstances. The factors that inform it include the nature and scope of the services you provide to the business, what comparable roles would pay in your industry and geographic area, the time you devote to the business, and the overall financial condition of the company.
According to IRS guidelines summarized by Thomson Reuters Checkpoint, relevant factors also include training and experience, duties and responsibilities, and the relationship between the owner's compensation and distributions taken. A company with strong profits and a shareholder taking minimal salary relative to distributions is the profile that invites scrutiny.
This does not mean your salary must equal your profits. It means your salary must be defensible. A well-documented compensation analysis — ideally prepared with your advisory team before year-end rather than after — is the foundation of a reasonable compensation position.
Distributions from an S-Corp are generally not subject to payroll taxes, which makes them an efficient way to take money out of the business — but only after reasonable compensation has been established. Distributions that effectively substitute for salary are reclassified as wages by the IRS, which creates retroactive payroll tax liability plus interest and penalties.
Year-end is a common time when S-Corp owners want to pull additional cash out of the business before the calendar year closes. That decision should be made in the context of your current salary level, your accumulated profits for the year, and your S-Corp basis. Taking a distribution when your basis is insufficient can create a taxable gain — a surprise that a proactive advisory conversation can prevent.
The Bradford Tax Institute has published analysis underscoring that S-Corp distributions are only protected from payroll taxes when the shareholder-employee compensation has passed the reasonable compensation threshold. There is no fixed ratio of salary to distributions that is universally safe — the answer depends on the facts of each business.
This is where many S-Corp owners discover the most immediate exposure. If your business income has grown during the year — through new clients, pricing increases, a strong quarter, or a one-time event — your estimated tax payments may no longer reflect what you actually owe.
The IRS estimated tax safe harbor rules provide some protection. Under the safe harbor, you can generally avoid underpayment penalties if you have paid in at least 100% of your prior year tax liability — or 110% if your adjusted gross income exceeded a threshold in the prior year. However, meeting the safe harbor avoids the penalty; it does not eliminate the balance due at filing. If your income has jumped significantly, you could owe a large amount in April even if you technically met the safe harbor threshold.
That gap — between what you paid in and what you actually owe — is one of the most common sources of the "surprise" tax bill that advisory clients describe when they come to us after years with a compliance-only accountant. Meeting the safe harbor is a floor, not a plan.
A year-end projection, done in November or early December, gives you a clear picture of where you stand and time to act — whether that means an additional estimated payment, an adjustment to your fourth-quarter salary, or both.
Pull your year-to-date profit and loss statement and compare it to your current W-2 wage level. If your business has been profitable and your salary appears low relative to what a comparable role would pay, that gap is worth addressing before year-end — both to stay compliant and to document your compensation decision in writing.
Your advisory team can help you benchmark your salary against industry data and build a compensation rationale that is defensible if questions arise later. This is not something you want to construct under audit pressure.
A projection — not an estimate, a real projection with your actual numbers — tells you whether your withholding and estimated payments are tracking toward your expected liability. It accounts for your W-2 wages, your S-Corp passthrough income, any other income sources, and the deductions you are likely to have available.
This projection should be the basis for any fourth-quarter decisions, including whether to make an additional estimated payment before January. According to IRS Publication 505, the fourth-quarter estimated payment deadline is typically in mid-January of the following year, which gives you a window to act if your projection reveals a shortfall.
Before taking any additional year-end distributions, verify that your S-Corp basis is sufficient to absorb them without creating a taxable gain. Your advisor can calculate your current basis using your beginning-of-year basis, passthrough income, and distributions taken to date. This is not a calculation you should attempt from memory.
If you are making a year-end change to your salary — up or down — document the reasoning. A brief written summary of the factors considered, the comparable roles reviewed, and the decision reached creates a contemporaneous record that supports your position. This is an area where an advisory firm can provide a written compensation analysis that holds up to scrutiny.
Year-end is the right time to set your compensation structure for the coming year, not January. Deciding on a salary level, a quarterly distribution cadence, and an estimated payment schedule — before the year begins — is the difference between managing your tax liability proactively and scrambling to manage it reactively.
| This is a fictional example to illustrate how the firm's advisory team would approach this situation. It does not represent a real client or actual past result. |
David runs a physical therapy practice in Virginia, organized as an S-Corp, with annual revenue of approximately $1.1 million. His practice has grown steadily over the past three years, largely through expanded cash-pay services and a new contract with a local employer group.
For most of that growth period, David's W-2 salary remained unchanged — he had set it at the beginning of his S-Corp election and simply rolled it forward each year without revisiting it. By early November of this year, his practice had generated close to $400,000 in net profit, but his annual salary was sitting at $90,000 — a number that would be difficult to defend as reasonable compensation for a licensed clinician running a seven-figure practice.
David also wanted to take a $75,000 distribution before year-end to fund a renovation of his office space. He had not yet run a projection for the year and was uncertain whether his quarterly estimated payments had kept pace with his actual income.
Our advisory team would guide David through a structured year-end review. First, we would work with him to document a reasonable compensation benchmark — reviewing Bureau of Labor Statistics data for physical therapist and practice owner roles in Virginia, as well as the duties he performs beyond clinical care, including hiring, billing oversight, and business development. Based on that analysis, we would recommend a salary adjustment that is both defensible and financially efficient.
Second, we would run a year-end projection to quantify the gap between his estimated payments and his expected tax liability. With the salary adjustment factored in, along with his passthrough income, we would determine whether an additional fourth-quarter payment is warranted and calculate the amount needed to either meet the safe harbor or close the gap substantially.
Third, before approving the $75,000 distribution, we would verify his current S-Corp basis and confirm the distribution would not create a taxable event. With basis confirmed, we would also help David calendar his distribution and payment timing to minimize unnecessary interest exposure.
The result would be a year-end that David actually feels prepared for — not one he pieces together in April.
If you see pieces of your own business in this hypothetical example, it may be time to sit down with our advisory team and talk through your options.
Business Advisory and Accounting Partners powered by Harness approaches S-Corp compensation as a planning function, not a filing checkbox. A compliance-focused firm may prepare your return using whatever salary you paid yourself during the year. A proactive advisory firm asks whether that salary was right — and works with you before year-end when you can still do something about it.
The distinction matters financially. An S-Corp owner who underpays reasonable compensation and then faces reclassification of distributions as wages can owe back payroll taxes plus interest and penalties. An owner who overpays salary unnecessarily increases payroll tax costs. Getting this right is not about finding the most aggressive position — it is about finding the right position, documented and defensible.
Our advisory team brings a Practice Forward methodology to each client relationship. That means structured planning cadences, proactive projections, and conversations that happen before the deadline — not after. We have been advising business owners since 1989 and offering formal business advisory services since 2014. The experience is in asking the questions that compliance-only accountants do not.
Any accounting firm can record history. Our advisory team helps you build a future — and that work starts now, not at tax time.
An advisory conversation about S-Corp compensation is a structured, strategic discussion — not a tax return review. You will walk through your current salary level, your year-to-date income and distributions, and your estimated tax position. You will leave with a clear picture of where you stand, what adjustments make sense before year-end, and what a smarter structure looks like for the year ahead.
These conversations are for S-Corp owners who want clarity on their compensation decisions — not owners looking for someone to simply file what they provide. There is no obligation to engage further beyond the initial meeting. Many owners simply want a second opinion before year-end. That is a completely reasonable starting point.
The conversation is professional, educational, and grounded in your actual numbers. It is the kind of meeting that a compliance-only accountant is rarely set up to have.

Reasonable compensation is the salary an S-Corp shareholder-employee must pay themselves for services provided to the corporation — defined by the IRS as what a similarly qualified individual would earn in the open market for the same role. It is evaluated based on factors including duties, experience, time devoted, and what comparable positions pay in your industry and geography. There is no universal dollar amount; the standard is facts-and-circumstances, which is why a documented compensation analysis is an important part of any S-Corp planning strategy.
You can take distributions in excess of your salary, but only after your salary meets the reasonable compensation standard — the IRS does not allow shareholder-employees to substitute distributions for wages as a strategy to avoid payroll taxes. If the IRS determines your salary is unreasonably low, it can reclassify distributions as wages, creating retroactive payroll tax liability plus penalties and interest. The right balance is one that is genuinely defensible, not simply the lowest number you can argue for.
If your S-Corp income has grown meaningfully during the year, your estimated payments may no longer be sufficient to cover your actual liability — even if you meet the IRS safe harbor threshold. The safe harbor prevents underpayment penalties by requiring you to pay at least 100% of your prior year tax (or 110% if your prior-year adjusted gross income exceeded a certain level), but it does not eliminate the balance you owe at filing. A year-end projection is the only reliable way to quantify the gap and determine whether an additional estimated payment is warranted.
The estimated tax safe harbor allows business owners to avoid underpayment penalties if they have paid in at least 100% of their prior year federal income tax liability — or 110% if their adjusted gross income in the prior year was above the applicable threshold. Paying in the safe harbor amount does not eliminate a balance due; it simply avoids the penalty on the underpayment. For business owners whose income has grown substantially, meeting only the safe harbor can still result in a significant tax bill at filing.
If the IRS determines that your S-Corp salary falls below the reasonable compensation standard, it can reclassify some or all of your distributions as wages. That reclassification triggers back payroll taxes — both the employer and employee share — plus interest on the unpaid amounts and potential penalties. The IRS has targeted S-Corp reasonable compensation as an ongoing compliance area, and low salary relative to high distributions is a known audit signal. A proactive advisory relationship that documents your compensation rationale annually is one of the most effective ways to manage this exposure.
There is no formula — the answer comes from analyzing what your role would command in the open market. Relevant inputs include your industry, geographic market, the scope of your duties, the time you devote to the business, and compensation data from sources such as the Bureau of Labor Statistics, industry salary surveys, or compensation benchmarking tools. Our advisory team regularly helps S-Corp owners build a documented compensation rationale that supports their salary decision and withstands scrutiny.
Yes — you can adjust your salary during the year, including at year-end, as long as the change is processed properly through payroll and the resulting annual salary still meets the reasonable compensation standard. A year-end salary increase must be reflected as actual wages paid before December 31 to count in the current tax year; you cannot retroactively assign wages on paper after the year closes. Working with an advisory team before year-end gives you the time and flexibility to make adjustments that are both compliant and tax-efficient.
The best time to have this conversation is before year-end — ideally in October or November — when you still have time to make payroll adjustments, run a projection, and plan your fourth-quarter estimated payment. Waiting until tax filing season limits your options significantly. Business Advisory and Accounting Partners works with S-Corp owners on exactly this type of year-end planning, and an initial advisory conversation is a low-obligation way to get a clear picture of where you stand.
