Tax Planning for Marketing and PR Agency Owners: The Decisions That Actually Set Your Bill

By Craig S. Cody, CPA, Certified Tax Coach.

Most marketing and PR agency owners overpay their taxes. It has almost nothing to do with missed deductions.

It has to do with timing. How you're structured, how you pay yourself, how client media runs through your books, what your retirement plan can hold, where your remote team sits. Those decisions set the number, and every one of them gets made during the year. By the time you're sitting with your accountant in March, the year is closed and most of those doors are shut.

That's the whole difference between tax preparation and tax planning. Preparation looks in the rearview mirror and reports what already happened. Planning looks through the windshield and changes what's about to happen.

I've spent 23 years reading agency books, and my firm works with more than 70 marketing and advertising agency owners every month. One of them saved $94,000 in the first year we planned together. That was a $1.5 million agency, measured in agency gross income. It wasn't one clever move. It was a handful of the decisions on this page, built properly, running at the same time.

This page walks through those decisions roughly in the order they matter, with the 2026 numbers attached. Each one is its own conversation. Where I've written the longer version, it's linked. The figures here are current for tax year 2026 and were last reviewed in September 2026.

Who This Page Is For

Owners of marketing, advertising, PR, creative and digital agencies. Typically 10 to 50 people. Agency gross income somewhere north of $1 million.

A word on that number, because it matters for everything below. Agency gross income, AGI, is what's left after the pass-through costs: the media, the printing, the freelancers you bill straight through. It isn't revenue and it isn't billings. And it isn't the adjusted gross income line on your 1040, which is a different number wearing the same initials. Every threshold on this page is in agency gross income unless I say otherwise.

Agencies have a specific set of tax problems that a generalist CPA rarely sees twice in a career. Pass-through media inflating your gross receipts. Delivery teams built on contractors. Employees scattered across six states. Retainer cash that arrives in lumps. And a services classification question that decides whether a six-figure deduction is yours or not.

If you run a $300,000 freelance shop, some of this applies. Most of it doesn't yet.

And if what you want from an accountant is a number in April and silence the rest of the year, this page isn't for you either. No judgment. That's a preparer relationship, and there are good preparers. This page is about the other kind.

What Is the Difference Between Tax Planning and Tax Preparation?

Preparation records the year. Planning changes it.

A preparer takes the facts as they landed on December 31 and puts the right numbers in the right boxes. That's real work and it has to be done well. But by the time it happens, your entity, your salary, your plan contributions, your purchase timing and your state footprint are all history. Filing a return isn't a tax strategy. It's the scorecard.

Planning happens in the year you're being taxed on. It's a conversation in May about what your salary should be for the rest of the year. It's a plan document adopted by October 1, not a regret in February. It's a decision in June about how the next media contract is written.

Here's the agency-specific version of the trap. An agency P&L can show a healthy profit while the bank account is thin, because so much of what moves through your books was never your money. Media and pass-throughs run through the account. Receivables stretch to 60 and 90 days. A retainer ends and the top line barely flinches while agency gross income drops by a third. A beautiful P&L can still bankrupt you, because profit is not cash.

A tax plan built on the P&L alone will be wrong in exactly the year you can least afford it. It has to sit on a cash forecast. That's why the strongest planning relationships I see are monthly, and why the plan gets revisited every time the numbers move.

Should My Agency Be an S Corporation?

For many agencies, yes, once owner profit is solidly between $250,000 and $350,000. It's usually the first structural lever, because it splits your income into two buckets taxed differently. Wages carry payroll tax. Distributions don't.

The mechanics are simple enough. The Social Security half of payroll tax stops at the 2026 wage base of $184,500. The Medicare half keeps going. Every dollar you take as a distribution instead of salary skips both.

The catch is reasonable compensation. You have to pay yourself a defensible salary for the work you actually do, and the IRS looks hard at owners who take a token salary and a large distribution. The number is a judgment call supported by your role, your hours, what you'd pay a stranger to do your job, and the size of the agency.

Set it too high and you hand over payroll tax you never owed. Set it too low and you've built an audit exposure into every return going forward. This isn't a number to guess at, and it isn't a number to leave alone for five years while the agency triples.

Here's what a generalist misses: in an agency, the salary decision pulls on three other numbers at the same time.

• The QBI deduction. Above the income threshold, your 20% deduction is capped by W-2 wages, and your own salary counts toward that cap. Cut your salary to save payroll tax and you can shrink the deduction at the same time.
• Your health insurance deduction. The S corporation owner's health insurance deduction is capped at your Medicare wages. An owner who cuts their own W-2 first when a retainer ends, which is exactly what most owners do, can zero it out on a return that files clean.
• Your retirement contributions. Employer contributions key off your W-2 compensation. A salary set for payroll tax alone can cap what the plan is allowed to hold for you.

Set the salary once a year with all four of those in view. Not payroll tax alone.

One more thing owners find surprising: an LLC isn't a tax entity. It's a liability wrapper. A single-member LLC is taxed as a proprietorship unless it elects otherwise, and you can change the tax treatment without touching the wrapper. I cover the entity decision as mistake three in the twelve biggest tax mistakes agency owners make, and the salary math as lever one in the five tax levers for agencies past $1 million in AGI.

Does My Agency Qualify for the QBI Deduction?

Usually yes, and more fully than the law firm or the accounting firm down the hall.

The Section 199A qualified business income deduction is 20% of qualified business income. Not 23%, which you'll see quoted everywhere. That figure was in the House-passed version of the 2025 tax bill and didn't survive into the law. And the deduction is now permanent. The old sunset provision was repealed outright by the One Big Beautiful Bill Act.

For a profitable agency owner, this is frequently the single largest deduction on the return. The question is whether your agency is a specified service trade or business, an SSTB, because SSTBs lose the deduction as income climbs.

The regulation lists thirteen SSTB fields: health, law, accounting, actuarial science, performing arts, consulting, athletics, financial services, brokerage, investing and investment management, trading, dealing in securities, and any business whose principal asset is the reputation or skill of its owners or employees. Advertising and marketing appear on none of them. Better still, the regulation expressly carves "sales, or economically similar services" out of the consulting category.

So agencies often keep the full 20% at income levels where law, accounting and consulting firms have lost it entirely. For 2026 the thresholds where the SSTB rules start to bite are $201,750 of taxable income on a single return and $403,500 on a joint return, with the phase-in running another $75,000 and $150,000 above that.

That advantage is real and it's winnable. But it has to be documented while it's happening, not reconstructed in March. How you describe services in your contracts. How you invoice. Whether you can show revenue by line, with execution work separated from advisory. Deciding after the fact that 87% of last year's revenue was execution, with nothing in the file to back it up, isn't a position. It's a hope.

The caveat is genuine. If a meaningful share of your revenue is billed as consulting, the analysis changes. Go read what your own engagement letters actually say.

And here's the part that bothers me most. Many times agency owners don't even know they've been wrongly phased out of QBI, because they're using a tax preparer, someone putting numbers in boxes, not a strategist. Nobody told them. The return just came back without the deduction, and nobody went back to look.

What Do I Do About Client Media Running Through My Books?

This is the agency-specific issue generalist CPAs miss most often, because no other kind of business has it.

If your clients' media budgets run through your books as your revenue, your gross receipts can look several times bigger than your agency actually is. A $6 million fee agency that places $28 million of media shows $34 million of gross receipts. That number crosses thresholds that were never written with a firm your size in mind.

The one that matters most is the Section 448(c) gross receipts test. For tax years beginning in 2026, a corporation or partnership passes it if average annual gross receipts over the prior three years don't exceed $32,000,000. Pass it and you can use the cash method and you're exempt from the Section 163(j) limit on deducting interest. Fail it because of money that was never yours, and you lose both.

There are two directions to work this, and both take lead time.

The first is contract structure. Whether media is your gross receipt or your client's depends on whether you're acting as principal or as agent, and that's a facts-and-circumstances question your contracts largely answer. Clients contracting directly with the vendor, or sequential liability language that makes it clear you're placing their money rather than spending yours, keeps that spend off your top line. This gets decided when the next master services agreement is drafted, not at year end.

The second is your accounting method, which gets its own section because it's worth its own decision.

Should My Agency Be on the Cash Method for Tax Purposes?

Maybe yes, if you pass the gross receipts test. But all agencies should keep their books on the accrual method. What does that mean? It means you keep your books on the accrual method to more accurately measure your financials but you may pay taxes on the cash method. Many agencies are on accrual by accident for taxes, rather than by decision, because that's how the books were set up on day one.

On the accrual method you're paying tax on invoices your clients haven't paid yet. For an agency whose clients stretch terms to 60 and 90 days, that's real money sitting in receivables and already taxed.

Changing methods for tax purposes is a formal accounting method change on Form 3115, with a catch-up adjustment that lands in the year of the change. An agency carrying $400,000 in receivables net of payables defers $400,000 of income in that year. At our firm we typically have a handful of new clients every year that we need to change from accrual to cash or cash to accrual for tax purposes and file Form 3115.

The honest part, which most content on this leaves out: this is a timing benefit, not a permanent one. You're moving the tax, not erasing it.

So why does it matter? Because of what the deferral frees up. That cash funds the retirement plan in the same year, and the plan contribution is a deduction that doesn't reverse. The move by itself is close to a wash. The value is in what it makes possible next. That pattern runs through all real planning work.

One clarification, because owners worry about it: the method you file on and the books you run the agency on don't have to match. Run the agency on accrual, because that's the only way to see your margin. Pay tax on cash. That's one set of books on the accrual method with an accrual to cash adjustment on the tax return. As a side note, we show the accrual to cash adjustment to our clients on a monthly basis so there are no surprises.

How Much Can I Actually Put Away for Retirement?

More than you think, and the plan you pick sets the ceiling.

For 2026 the numbers are these. Your own salary deferral into a 401(k) is $24,500, plus $8,000 if you're 50 or older, or $11,250 if you're 60 to 63. Total annual additions to that account, deferrals plus employer money, cap at $72,000. And a defined benefit or cash balance plan is measured against an annual benefit limit of $290,000, which is a different universe.

A solo 401(k) works if it's just you. Once you have staff, a safe harbor 401(k) with a cross-tested profit-sharing design lets you direct a disproportionate share of the contribution to the owner while still passing the nondiscrimination tests. The required safe harbor contribution for the team is the price of admission, and for a profitable owner it's usually a bargain. Above that, a cash balance plan layered on top can move six figures a year into a deductible, creditor-protected account.

I've had many clients put an additional $100,000 or more away every year using that structure.

Agencies have an advantage here that almost nobody writes about, because every cash balance article in existence is written for physicians. Section 404(a)(7) can force a pension and a 401(k) to share one deduction limit, squeezing employer money toward 6% of pay instead of 25%. But that combined limit only applies when the pension plan is exempt from PBGC coverage. PBGC's coverage rules exempt professional service employers whose plan has never covered more than 25 active participants, the doctors and lawyers and accountants named in ERISA section 4021(c)(2), and plans that cover only substantial owners. A marketing agency with a real W-2 team generally isn't a professional service employer under that definition, so the squeeze that hits every doctor never reaches you.

Two qualifiers, and both matter. An owner-only plan is exempt as a substantial-owner plan, so a solo owner is squeezed exactly like a physician. Payroll, not income, decides it. And the professional service list isn't exclusive, so the right move is a PBGC coverage determination for your plan, not an assumption.

Two more things. A cash balance plan is a funding commitment you have to be able to meet in a bad year, which is exactly why it gets designed alongside a twelve-month cash forecast and never in isolation. And never trust a contribution table in an article, including mine. Credits depend on your age, your years to retirement and the plan's interest crediting rate. Anyone quoting you a number before they've seen your census is showing you a sales illustration.

Deadlines make this a first-half decision. A new safe harbor 401(k) generally has to be in place by October 1 to count for the year. The longer versions are in cash balance plans for agency owners and, if your state has sent you a retirement mandate notice, state-mandated plans versus your own 401(k).

Should My Agency Own Its Office?

Maybe. And I'll tell you straight: I don't own the building my firm operates out of, so this isn't a lever I've pulled myself. It's one I've watched work for clients, and I know who it works for.

The structure is simple. You buy the building through a separate LLC you own. Your agency signs a lease at market rent and pays it. The rent is still deductible to the agency, and it lands in an entity you control instead of a landlord's account. Depreciation shelters the rental income on the other side.

Then comes the part that makes the numbers move. A cost segregation study breaks the building into its components and reassigns them from 39-year depreciation into 5-, 7- and 15-year lives. With 100% bonus depreciation now permanent for property acquired after January 19, 2025, those reclassified components can be written off in year one instead of over four decades. On a typical commercial building, 20% to 25% of the basis reclassifies.

Three mechanics decide whether this works or blows up.

• The rent has to be at fair market value and supported. A number you invented to move money is the first thing an examiner tests. Get a written lease and a comparable.
• The self-rental rule changes what the income does. Under the passive activity regulations, net rental income from property you rent to a business you materially participate in is recharacterized as nonpassive. Practically, that means it won't soak up passive losses from your other investments, which is what most people assume it will do.
• The building never goes inside the operating company. Liability is one reason. The bigger one is the sale: a buyer wants the agency, not the real estate, and you want to keep the rent stream after you've sold the business. Unwinding a building out of an operating company later is expensive.

Who it's for: an owner who plans to stay put for seven years or more, in a market they're not leaving, with a down payment that isn't also the agency's cash reserve. Who it isn't for: an agency that might shrink, relocate or go remote, or an owner whose down payment is the only cushion under the payroll. Lever three of the five levers article works the numbers on a $1.5 million building.

Are My Contractors Actually Contractors?

Whatever your agreement says, the IRS and your state get the final word.

Agencies run on freelancers: designers, developers, copywriters, editors, fractional strategists. It's one of the ways owners keep people costs under control, and it's also where I see one of the most expensive surprises in the business.

Federally, classification turns on a common-law control test: who directs the work, who bears the financial risk, and what the relationship looks like in practice. Several states, California and New Jersey among them, apply a stricter ABC test. So a freelancer who's a contractor for federal purposes can be an employee in the state where they sit.

The exposure is asymmetric. Get it right and you've saved payroll tax and benefits cost. Get it wrong and you owe back payroll taxes, penalties and interest on humans you've been paying for years, plus the state's version on top.

The fix is mostly documentation and operating practice. Written agreements that say what they are. A W-9 on file. Project-based scoping instead of open-ended hours. Contractors who actually have other clients. The same treatment for everyone doing the same job. A 1099-NEC every January. And not handing a "contractor" a company email address, a manager and a standing seat in your Monday status meeting.

So ask yourself the question now. Are you documenting that your contractors are contractors? Written agreements, their invoices, everything buttoned up? The last thing you want is a problem during due diligence, or a notice from the IRS or the state, with no documentation at the ready. We've seen both of those, and the prepared business is the business that passes.

Do I Owe Tax in States Where My Employees Live?

Often, yes. And it usually starts with one hire.

A single employee working from another state generally creates payroll registration and withholding obligations there, and often income tax nexus for the agency itself. Your client list matters too: most states now apportion service income by where the customer is, not where the work was done, so your client roster is your tax map.

About half of the agencies my firm works with have a multi-state filing requirement, and many of them didn't know it when they arrived. They came from a generalist CPA who never asked where the humans on the team lived or where the clients were.

Layered on top is the pass-through entity tax election. The federal deduction for state and local taxes is capped at $40,400 for 2026, and it phases down above $505,000 of income to a $10,000 floor. Most states with an income tax now let the entity itself pay the state tax and deduct it federally, which works around that cap for owners. Whether it helps you depends on your states and your personal return, and it has to be elected, often with a payment, by a specific date.

One more reason to get this clean now rather than later. You don't want $150,000 going into escrow at closing because a buyer thinks you had filing responsibilities in states you never filed in.

I've written the two halves of this separately: your client list is your tax map covers the sales side, and one remote hire can put your agency on the hook covers the people side.

What Can I Still Do in the Fourth Quarter?

More than people think.

Retirement plan contributions, and in some cases plan adoption. Bonus timing. Billing and collection timing if you're on the cash method. Charitable strategies, if giving is already part of your plan. Equipment and technology placed in service before year end. Looking at the planning strategies the agency has used but not documented.

On equipment, the 2026 Section 179 expensing limit per Rev. Proc. 2025-32 is $2,560,000, with the dollar-for-dollar phase-out beginning at $4,090,000 of qualifying property placed in service, and a $32,000 cap on heavy SUVs. One hundred percent bonus depreciation sits alongside it with no dollar cap and no income limitation. That last part matters in a loss year, because bonus can create a net operating loss where Section 179 can't.

Here's the honest version. Fourth-quarter moves can turn into big dollars. The entity structure, the compensation model, the SSTB documentation, the accounting method and the retirement plan design are the big ones, and every one of those belongs in the first half of the year but can be corrected in the second half of the year. If the first time you hear from your CPA is November, you're not getting the big dollars, you're getting the small dollars.

What Does Proactive Tax Planning Cost, and What Does It Return?

My firm has never priced by the hour. We've always priced on the deliverable. What you pay for is the insight, and then the right numbers in the right boxes.

In practice that's a one time tax plan and then a monthly relationship, not a spring appointment. Our packages come in three sizes, and every one of them includes a monthly meeting with a CPA-led team, financial reviews built on agency metrics, tax projections, continuous planning through the year, and both the business and personal returns. The larger packages add cash flow forecasting and CFO-level work. What you never pay for is a clock.

What does it return? An outcome I can point to is the one that opened this page: $94,000 saved in year one for a $1.5 million AGI agency. I've had many clients put $100,000 or more a year into a cash balance plan on top of their 401(k). One client received a real research credit of more than $125,000 for a single year.

Those are the strong cases, and I'd rather tell you that than let you assume they're typical. Some analyses come back smaller. An agency that's already an S corporation with a well-set salary, a maxed plan and clean state filings has less room, and the honest answer there is a shorter list.

That's what the Free Tax Analysis is for. You upload your last two filed returns and you get back a line-by-line review, a dollar estimate of what was missed, the agency-specific opportunities most CPAs overlook, a simple plan for lowering the next bill, and a consultation to walk through it. You find out which case you are before you pay for anything. You walk away with real insights you can use, even if we never work together.

A CPA should be an income item, not an expense. If yours isn't, that's the first thing to fix.

How Do I Know If My CPA Is Planning or Just Preparing?

Ask five questions. You can do this Monday morning.

1. What did you change for me last year? Not what you filed. What you changed. If the answer is a pause, you have a preparer.
2. When is our next meeting before year end? If there isn't one on the calendar, nothing on this page is going to happen for you this year.
3. What's my reasonable compensation, and when did we last revisit it? A number set five years ago at a third of today's profit is a problem in both directions.
4. Am I a specified service business, and what in my file documents that? If your CPA has to look up what an SSTB is, the deduction is at risk.
5. What's the ceiling on my retirement plan, and why that plan? "Because it was easy to open" is an answer. It's not a plan.

Good preparers exist, and I mean that. But a preparer conversation and a tax advisor conversation are two different conversations, and the second one is the only one that changes the number.

Frequently Asked Questions

Is tax planning the same as tax preparation?

No. Preparation reports what already happened and is backward-looking by definition. Planning changes what happens, and it has to occur during the year you're being taxed on, before the books close.

When should a marketing agency owner start tax planning?

In the first half of the year, and no later than the third quarter. Entity elections, salary decisions, plan adoption and contract structure all have deadlines during the year. By January of the following year, nearly every decision that set the number has already been made.

Do marketing and PR agencies qualify for the 20% QBI deduction?

Generally yes, and more fully than most professional firms. Advertising and marketing are not among the thirteen specified service fields in the regulations, so the deduction doesn't phase out with income the way it does for law, accounting or consulting practices. If a meaningful share of your revenue is billed as consulting, get the classification confirmed and documented before relying on it.

What does AGI mean for a marketing agency?

Agency gross income: revenue minus pass-through costs like media, printing and freelancers billed straight through to the client. It's the number the agency actually lives on, and it's not the adjusted gross income line on a personal tax return. Every income threshold on this page is in agency gross income unless stated otherwise.

Is an S corporation always the right structure for an agency?

No. It's usually right once owner profit is solidly into six figures, but the salary it requires interacts with the QBI deduction, the owner's health insurance deduction and retirement contributions. An owner who sets salary for payroll tax alone can lose more on the other three than they save. Run the whole picture, not one line.

Can a marketing agency use the cash method for taxes?

Usually yes. A corporation or partnership can use the cash method if its average annual gross receipts over the prior three years don't exceed $32,000,000 for tax years beginning in 2026. The catch for agencies is that client media running through your books as revenue counts toward that test. Switching from accrual is a formal accounting method change on Form 3115, and it defers income rather than eliminating it.

My CPA says I'm fine. How do I know?

Ask what they changed for you last year. If they filed your return and you didn't hear from them between April and the following February, you have a preparer, not a planner. A preparer can be excellent at their job and still leave every decision on this page unmade.

Let's Talk

None of this is a trick. Every decision on this page is in the code, and every one of them is available to you. It just doesn't happen by itself, and it doesn't happen in March. The agencies that flourish through a slow year, a growth spurt or a sale are the ones that made these decisions on purpose.

If you want to know which of these decisions are yours to make this year, that's a specific answer, and it takes reading your actual returns.
