Business Owners: Your Q3 Payment Is Due, but the Bigger Issue Is What Happens Next

By Dr. Jose G. Cardenas | Chief Tax Strategist, The C & R Group, LLC

Today is September 15.

For many business owners, independent contractors, investors, and taxpayers with income not fully covered by withholding, that means one thing:

Your third 2026 estimated-tax payment is due today.

For calendar-year individuals, September 15 is the due date for the estimated-tax installment covering the June 1 through August 31 payment period. The IRS also lists September 15 as the third estimated-tax installment date for calendar-year corporations. (IRS)

So yes:

Make the payment.

But then do not close the spreadsheet.

Do not put the tax file back in the drawer.

Do not say:

“Good. Taxes are handled until next year.”

Because they are not.

The more important question begins immediately after today's payment:

What happens next?

September through December can change the entire tax picture.

Your business may have its strongest quarter.

A large contract may close.

You may pay bonuses.

You may purchase equipment.

You may take distributions.

Investment gains may occur.

Your spouse may receive a year-end bonus.

Retirement contributions may change.

And the next general estimated-tax installment for the September 1 through December 31 period is due January 15, 2027. (IRS)

That means today's payment is not the finish line.

It is the starting point for the final tax-planning phase of 2026.

Pay Q3 today. Plan Q4 tomorrow.


1. Today's Payment Is Based on What Already Happened

The September 15 estimated-tax period generally covers:

June 1 through August 31. (IRS)

Those months are over.

The revenue happened.

The profit happened.

The investment gains happened.

Today's payment deals primarily with tax exposure created by financial activity already behind you.

But September 1 through December 31 is still unfolding.

That gives the business owner something valuable:

time.

Time to project.

Time to adjust.

Time to fund.

Time to make better decisions before December 31 closes the door on many current-year planning opportunities.


2. Do Not Confuse “Payment Made” With “Tax Plan Complete”

A business owner makes today's estimated payment:

$15,000

and thinks:

“Great. Taxes are handled.”

Not necessarily.

Suppose the business generates:

January–August profit

$180,000

but expects:

September–December profit

$140,000

Projected annual profit:

$320,000

The Q3 payment does not address all of that future Q4 profit.

Your tax plan needs to continue.

Estimated tax is a pay-as-you-go system. The IRS explains that taxpayers generally must pay tax as income is earned or received through withholding, estimated payments, or both. (IRS)

So the bigger question after today's payment is:

What are the next four months likely to create?


3. Start With Updated Year-to-Date Profit

Business owners should know, as of August 31:

Revenue

$________

Cost of goods sold

$________

Gross profit

$________

Operating expenses

$________

Net profit

$________

Not:

“Sales have been pretty good.”

Not:

“We have money in the bank.”

Actual numbers.

Those numbers tell you where Q4 planning begins.


4. Compare Actual Profit With the January Projection

Suppose January projection:

$150,000 annual profit

Actual profit through August:

$170,000

You have already exceeded the entire original annual estimate.

That means your:

  • Estimated-tax plan;

  • tax reserve;

  • owner-compensation analysis;

  • retirement strategy;

  • distribution plan

may all need updating.

The January projection did not fail.

The business changed.

The tax strategy should change with it.


5. Project September Through December

Now forecast Q4.

Contracted revenue

$________

Probable additional revenue

$________

Payroll

$________

Contractor costs

$________

Rent

$________

Insurance

$________

Marketing

$________

Equipment

$________

Other operating expenses

$________

Projected Q4 profit:

$________

Then:

YTD profit

$________

plus

Projected Q4 profit

$________

equals:

Projected full-year profit

$________

That is one of the most important numbers in your year-end plan.


6. Do Not Simply Annualize Eight Months

If profit through August is:

$200,000

you might multiply by:

1.5

and estimate:

$300,000

for the year.

Maybe.

But businesses are seasonal.

Q4 may include:

  • Holiday demand;

  • major contract completions;

  • annual renewals;

  • bonuses;

  • insurance costs;

  • equipment purchases.

A good projection uses the business you actually operate.

Not merely a calculator.


7. Today's Payment Should Trigger the January 15 Forecast

The next general estimated-tax payment period covers:

September 1 through December 31

with payment generally due:

January 15, 2027. (IRS)

That means today is an excellent time to estimate that January payment.

Not the exact dollar.

A planning range.

Low Q4 scenario

January payment estimate:

$________

Expected Q4

$________

Strong Q4

$________

Now you can begin reserving cash.


8. The IRS Lets You Update Estimates When Income Changes

Estimated payments are not required to remain frozen throughout the year.

Publication 505 contains an Amended Estimated Tax Worksheet specifically for taxpayers whose estimated tax changes during the year. For a payment due September 15, the worksheet generally applies 75% of the amended annual estimated tax before subtracting prior estimated payments. (IRS)

That matters because business income rarely behaves perfectly.

If income changes:

Recalculate.

If profit grows:

Recalculate.

If income falls:

Recalculate.

Estimated tax should respond to reality.


9. Build the Q4 Tax Reserve Now

Suppose you project:

Additional January tax payment

$32,000

Do not wait until January 14.

Four months gives you approximately:

$8,000 per month

to reserve.

That is a much different cash-flow problem than:

“We need $32,000 tomorrow.”

Create:

Current tax reserve

$________

January target

$________

Gap

$________

Monthly reserve requirement

$________

That turns a tax bill into a planned business expense.


10. Separate Tax Cash From Operating Cash

The bank account might show:

$250,000.

But that money may already belong to:

  • Payroll;

  • vendors;

  • debt payments;

  • payroll taxes;

  • sales tax;

  • income taxes.

Your checking balance is not the same thing as:

available owner cash.

Create separate mental—or actual—buckets.

Operating reserve

$________

Payroll obligations

$________

Vendor obligations

$________

Tax reserve

$________

Truly discretionary cash

$________

Now you can make better decisions.


11. Review Owner Distributions Before Taking Them

Business owners love distributions.

Understandably.

That is why you built the business.

But Q4 distributions should come after:

tax planning.

Suppose you want:

$75,000 distribution.

Before taking it, ask:

  • Is Q4 payroll funded?

  • Is the tax reserve funded?

  • Are vendors covered?

  • Is January operating cash protected?

  • Has shareholder or partner basis been reviewed where relevant?

A distribution should not create a January emergency.


12. Profit and Distribution Are Not the Same Thing

This remains a major misunderstanding.

Suppose your S corporation produces:

$250,000 of taxable pass-through income.

You distribute only:

$100,000.

The taxable income is not necessarily limited to:

$100,000.

Likewise, taking:

$100,000 distribution

does not automatically create:

$100,000 business deduction.

Profit.

Compensation.

Distribution.

Cash.

These are different concepts.

Your Q4 plan should distinguish them.


13. Review S Corporation Owner Compensation

If you are a shareholder-employee:

Review:

W-2 wages YTD

$________

Projected annual wages

$________

Projected business profit

$________

Distributions

$________

If the business dramatically outperformed the original plan:

Reasonable compensation deserves another look.

September leaves time to make appropriate payroll adjustments.

December 29 is a far worse time to start that analysis.


14. Payroll Should Be Part of the Tax Projection

Q4 payroll affects:

  • Cash flow;

  • employer payroll taxes;

  • business deductions;

  • owner compensation;

  • employee bonuses.

Project:

Regular payroll

$________

Bonuses

$________

Payroll taxes

$________

Benefits

$________

Then include those amounts in the Q4 profit forecast.


15. Review Employee Bonuses Before Promising Them

Suppose the owner wants to pay:

$50,000 total employee bonuses.

Excellent.

But calculate:

  • Bonus payroll;

  • employer taxes;

  • operating cash;

  • January obligations.

A bonus program should reward employees without accidentally starving the business of Q1 working capital.

Plan the economics before making promises.


16. Review Retirement Contributions

A profitable year can create an opportunity to accelerate retirement savings.

Possible business plans may include:

  • 401(k);

  • Solo 401(k);

  • SEP IRA;

  • SIMPLE IRA;

  • other qualified plans.

But the objective should not be:

“How do we dump money somewhere to avoid taxes?”

The better question:

“Does additional retirement funding support the owner's long-term plan, and what does it do to the current tax projection?”

Run both scenarios.


17. Run the Retirement Contribution Scenario

For example:

Scenario A

No additional retirement contribution.

Projected taxable income:

$________

Projected tax:

$________

Scenario B

Additional qualifying contribution:

$________

Projected taxable income:

$________

Projected tax:

$________

Then consider:

  • Tax savings;

  • cash required;

  • retirement benefit;

  • employee obligations.

A tax deduction is only one part of the decision.


18. Review Major Equipment Purchases

Q4 is when many business owners start hearing:

“Buy equipment before December 31 to save taxes.”

Maybe.

If you actually need the equipment.

Suppose you were already planning:

$80,000 machinery purchase.

Now evaluate:

  • Timing;

  • financing;

  • cash flow;

  • placed-in-service requirements;

  • available depreciation treatment.

That is good planning.


19. Do Not Spend $100 to Save $30

This deserves its own section.

Business owner:

“I need more write-offs.”

So they spend:

$100,000

on something the business did not need.

Even if the expense or deduction ultimately reduces tax significantly:

The business still spent:

$100,000.

A tax deduction reduces taxable income.

It does not magically reimburse every dollar spent.

Do not make the company poorer to make the tax return look prettier.


20. Review Fixed Assets Now

Update the asset list:

  • Equipment;

  • computers;

  • furniture;

  • vehicles;

  • machinery;

  • improvements.

For each:

Cost

$________

Purchase date

________

Placed-in-service date

________

Business-use percentage

________

Your year-end depreciation estimate cannot be accurate if the fixed-asset records are incomplete.


21. Review Capital Gains Outside the Business

The business owner's personal tax return may also contain:

  • Stock gains;

  • dividends;

  • interest;

  • cryptocurrency gains;

  • rental income.

Do not project:

business tax

in isolation from:

household tax.

Suppose business profit:

$250,000

and personal long-term gains:

$75,000.

That investment activity can materially change the household tax picture.


22. Review Capital Losses

Track:

Realized losses

$________

Unrealized losses

$________

Carryforward

$________

Losses may offset capital gains under applicable rules.

But do not sell investments simply to manufacture a tax result.

Investment strategy first.

Tax awareness always.


23. Review NIIT Exposure

Higher-income business owners may also have:

  • dividends;

  • interest;

  • capital gains;

  • passive rental income.

That may create exposure to the:

3.8% Net Investment Income Tax

depending on household income and the character of the income.

A successful business year can indirectly change investment-tax consequences.

The return works as one system.


24. Review QBI

Qualified Business Income planning deserves another look after Q3.

Why?

Because the calculation may depend on:

  • taxable income;

  • business type;

  • W-2 wages;

  • qualified property;

  • capital gains;

  • other limitations.

A January estimate built around:

$120,000 profit

may be meaningless when the business is now projected to earn:

$350,000.

Run QBI using updated numbers.


25. Review Charitable Giving

If you intend to make substantial Q4 charitable gifts:

Plan now.

Especially when:

  • Appreciated securities;

  • donor-advised funds;

  • significant noncash property

may be involved.

Do not wait until the final week of December.

Complex transfers take time.

And selling appreciated assets before discussing charitable goals can eliminate potential planning choices.


26. Review Accounts Receivable

Business profit does not always equal cash.

Suppose:

Profit

$300,000

but:

Accounts receivable

$180,000

That means a large portion of economic activity has not yet turned into cash.

Tax obligations and accounting-method rules can complicate this further.

At minimum:

Know your AR.

Current

$________

30+ days

$________

60+

$________

90+

$________

A tax strategy that ignores collections can create a liquidity problem.


27. Accelerate Collections for Business Reasons, Not Just Taxes

The final quarter is an excellent time to tighten collections.

Not because every collection necessarily produces a favorable tax result.

Because:

cash flow matters.

A profitable business with poor collections may struggle to:

  • pay taxes;

  • fund payroll;

  • invest;

  • distribute cash.

Financial strength begins with turning revenue into cash.


28. Review Accounts Payable

Also know:

Vendor obligations

$________

Credit cards

$________

Payroll liabilities

$________

Taxes payable

$________

Debt obligations

$________

A large bank balance means far less when large liabilities sit behind it.


29. Review Business Debt

Separate:

Principal

from

Interest.

If the business pays:

$10,000 monthly loan payment

the entire $10,000 is not necessarily an ordinary business-interest deduction.

Understanding debt service is essential for:

  • tax projection;

  • cash-flow planning.


30. Review State Taxes

Federal estimated tax is only one piece.

Business owners may also face:

  • state income tax;

  • franchise tax;

  • entity-level taxes;

  • payroll taxes;

  • sales-tax obligations.

If profit increased:

State-tax exposure may increase too.

Do not fund the federal reserve while ignoring the state bill.


31. Review Multi-State Activity

Did you:

  • hire remote employees?

  • serve clients in new states?

  • open another location?

  • move your headquarters?

  • perform services across state lines?

That can create:

  • nexus;

  • filing requirements;

  • withholding obligations;

  • apportionment issues.

Business expansion can create tax obligations long before the owner realizes it.

Q4 is a good time to identify them.


32. Review Sales-Tax Compliance

Sales tax collected from customers is not:

business profit.

Reconcile:

Collected

$________

Remitted

$________

Payable

$________

Do not spend money that belongs to the taxing authority.

That lesson becomes particularly important when Q4 sales surge.


33. Review Payroll-Tax Compliance

Confirm:

  • Federal payroll deposits;

  • state withholding;

  • unemployment taxes;

  • payroll filings.

Income-tax strategy does not compensate for payroll-tax problems.

Compliance comes first.

Strategy builds on top of it.


34. Review Contractor Records

Before January:

Make sure contractors have:

  • Valid W-9s;

  • correct names;

  • tax identification information;

  • properly recorded payments.

Do not wait until information-return season to chase people you paid nine months earlier.

Q4 preparation starts now.


35. Review Your Entity Structure—but Do Not Panic-Change It

A business that expected:

$40,000 profit

and is now projected at:

$250,000

may deserve an entity review.

But:

Do not change entities because of one social-media video promising:

“Pay zero taxes with an S corp.”

Evaluate:

  • Payroll;

  • reasonable compensation;

  • administrative costs;

  • state rules;

  • timing;

  • long-term plans.

A structure should solve a real problem.


36. Review Planned Owner Purchases

If the owner intends to use business cash for:

  • Home purchase;

  • vehicle;

  • travel;

  • investments;

  • personal debt payoff;

first determine:

How will the cash reach the owner?

Wages?

Distribution?

Loan?

Reimbursement?

Different methods can have different accounting and tax implications.

Do not blur business and personal money.


37. Review Accountable-Plan Reimbursements Where Applicable

If an owner or employee pays legitimate business expenses personally, an appropriately structured accountable reimbursement arrangement may deserve review.

Documentation matters.

Business purpose matters.

Receipts matter.

Do not wait until December to recreate nine months of expenses from memory.


38. Review Home-Office Facts

For business owners who legitimately use part of the home for business:

Review:

  • Exclusive use;

  • regular use;

  • business purpose;

  • applicable taxpayer/entity structure.

Do not simply calculate:

“20% of my house is deductible.”

Home-office treatment depends on facts and business structure.

Get the mechanics right.


39. Review Vehicle Records

Before year-end:

Check mileage logs.

Business miles

________

Total miles

________

Vehicle expenses

$________

Business-use percentage

________

December is not the time to reconstruct January mileage by scrolling through your calendar and hoping for divine intervention.

Maintain contemporaneous records.


40. Review Travel and Meal Documentation

Business travel and meal deductions require:

  • Business purpose;

  • appropriate substantiation.

Review now.

Do not let legitimate deductions disappear because the documentation is poor.

A good strategy without documentation is just an interesting theory.


41. Review the Household Withholding Picture

Business owners often have spouses receiving W-2 income.

Suppose:

Spouse wages

$130,000

Federal withholding

$20,000

Additional withholding through remaining paychecks may potentially be one tool for addressing household tax exposure.

The IRS notes that employees may increase withholding by filing a new Form W-4 rather than relying solely on estimated payments. (IRS)

Run the numbers before deciding.


42. Safe Harbor Is Still Not the Same as Full Funding

The general IRS estimated-tax rule says individuals typically must make estimated payments if they expect to owe at least $1,000 after withholding and credits and expected payments fall below the smaller of 90% of current-year tax or generally 100% of prior-year tax, subject to special rules for certain taxpayers. (IRS)

But meeting that requirement does not necessarily mean:

“Nothing will be due in April.”

You can satisfy a safe harbor and still owe a large balance.

Business owners should plan for:

compliance

and

cash.


43. Underpayment Can Be Measured by Payment Period

The IRS notes that if you do not pay enough tax by the due date for a particular payment period, a penalty can apply even if the final return ultimately shows a refund. (IRS)

That is why estimated-tax timing matters.

You cannot always repair every earlier payment-period issue simply by making one huge payment later.


44. Uneven Income May Require a Different Analysis

Some businesses do not earn income evenly.

Maybe:

Q1 profit

$15,000

Q2

$30,000

Q3

$150,000

If income is highly uneven, the annualized income installment method may deserve review when calculating estimated-tax penalty exposure.

Publication 505 points taxpayers to the annualized-income method for situations where income varies during the year. (IRS)

That is particularly relevant for seasonal businesses.


45. Do Not Automatically Assume Four Equal Payments Are Optimal

Estimated taxes are often described as:

quarterly.

That can lead people to think:

Four equal checks.

But the IRS payment periods themselves are not equal calendar quarters, and income can vary throughout the year. (IRS)

Your strategy should reflect:

  • income timing;

  • withholding;

  • applicable estimated-tax rules.


46. The Next Four Months Should Have a Tax Calendar

Create one now.

September

  • Make Q3 payment.

  • Update projection.

  • Fund tax reserve.

October

  • Review business profit.

  • Review retirement.

  • Review investment gains/losses.

November

  • Update Q4 forecast.

  • Finalize charitable planning.

  • Review major purchases.

December

  • Execute appropriate year-end actions.

  • Confirm tax reserve.

  • Update January payment.

January 15

  • Make Q4 estimated payment if required.

Now tax planning becomes an operating rhythm.


47. Schedule Monthly P&L Reviews

From now through December:

September 30

Close the month.

October 31

Close the month.

November 30

Close the month.

Then:

Update projected annual profit after each close.

Business owners should not enter January still wondering:

“How much money did we make last year?”

Know before the year ends.


48. Measure the Tax Gap Monthly

Create this simple formula:

Projected total tax – projected tax payments = projected tax gap

Example:

Projected federal tax:

$85,000

Projected withholding:

$25,000

Estimated payments:

$40,000

Projected remaining gap:

$20,000

Then compare:

Tax reserve:

$12,000

Reserve shortage:

$8,000

Now the action is obvious.


49. Protect Q1 2027 Before Taking Year-End Cash

Q4 success creates temptation:

big year-end distribution.

Before doing that, project:

January payroll

$________

January vendors

$________

Debt payments

$________

January estimated tax

$________

Minimum operating reserve

$________

Then decide what is safely distributable.

Do not start 2027 broke because 2026 looked profitable.


50. Know the Difference Between Tax Minimization and Wealth Building

This is the most important business-owner lesson in the article.

Your mission is not merely:

Pay the least tax possible this year.

Your larger mission is:

Build more after-tax wealth over time.

Sometimes that means:

  • Taking a legitimate deduction.

  • Funding retirement.

  • harvesting a loss.

  • accelerating an appropriate expense.

Sometimes it means:

  • Paying the tax;

  • keeping cash;

  • avoiding unnecessary spending;

  • maintaining business liquidity.

A lower tax bill does not automatically mean a stronger business.


Illustrative Case Study: The Owner Who Paid Q3 and Stopped Thinking

Meet:

Marcus

Marcus owns a successful service company taxed as an S corporation.

January projection:

Annual revenue

$750,000

Annual profit

$175,000

Estimated payments were built around that forecast.


September 15

Marcus makes his scheduled Q3 payment:

$12,000

He thinks:

“Good. Taxes handled.”

But the books show something else.


Actual Through August

Revenue

$680,000

Expenses

$430,000

Profit

$250,000

He has already exceeded the original full-year profit projection by:

$75,000

And four months remain.


Q4 Forecast

Signed contracts:

$260,000

Expected Q4 expenses:

$155,000

Projected Q4 profit:

$105,000

Projected annual profit:

$355,000

Original:

$175,000

Difference:

+$180,000

That should change the conversation.


Marcus's Household Also Has Other Income

Spouse wages:

$95,000

Dividends:

$10,000

Long-term capital gain:

$35,000

Now the household tax plan is materially different from January.


What Happens If Marcus Stops Planning Today?

Q4 arrives.

He sees strong cash.

He takes:

$100,000 owner distribution.

Buys:

$60,000 vehicle

mostly because someone tells him:

“It's a write-off.”

Pays:

$25,000 employee bonuses.

January arrives.

Tax adviser calculates a major remaining tax liability.

Business cash is tight.

Marcus asks:

“How can I owe this much? I made all four tax payments.”

Because the payments were based on:

an outdated profit projection.


The Better Version

Marcus makes today's Q3 payment.

Then immediately runs the new projection.

Projected annual profit:

$355,000

Household income:

Updated.

Federal tax:

Updated.

State tax:

Updated.

January payment:

Estimated.

Tax reserve:

Increased.


Step 1 — Protect the Tax Reserve

Marcus moves:

$________

into a dedicated tax account.


Step 2 — Protect Q1 Operating Cash

He calculates:

Payroll

$________

Vendors

$________

Debt

$________

January taxes

$________

before determining his distribution.


Step 3 — Review the Distribution

Instead of blindly taking:

$100,000

he evaluates:

$________

based on the actual available surplus.


Step 4 — Review the Vehicle

Does the company actually need:

$60,000 vehicle?

If yes:

Review tax treatment.

If no:

Do not spend $60,000 chasing a deduction.


Step 5 — Review Retirement

Marcus already wanted to increase retirement savings.

Now the adviser models appropriate plan contributions.

Business objective:

retirement wealth

Tax benefit:

secondary advantage.


Step 6 — Review Investment Gains

The household's $35,000 capital gain enters the projection.

Available capital losses are reviewed.

NIIT is reviewed where applicable.


Result

Marcus still has a successful year.

He may still:

  • Take a distribution;

  • buy equipment;

  • fund retirement;

  • pay bonuses.

The difference?

He does them with:

the tax bill already visible.

That is the bigger issue after September 15.

Is the third individual estimated-tax payment due September 15, 2026?

Yes. For calendar-year individuals, the third 2026 estimated-tax installment is due September 15 and generally covers income from June 1 through August 31. (IRS)

When is the next individual estimated-tax payment due?

The next general installment, covering September 1 through December 31, is due January 15, 2027. (IRS)

Can estimated-tax payments be changed during the year?

Yes. IRS Publication 505 provides an amended estimated-tax worksheet for taxpayers whose projected annual tax changes during the year. (IRS)

Who generally may need estimated tax?

Estimated tax may be required when tax is not sufficiently covered by withholding. Common income sources include self-employment income, interest, dividends, rents, and capital gains. (IRS)

What is the general estimated-tax rule for individuals?

In most cases, taxpayers generally need estimated tax when they expect to owe at least $1,000 after withholding and credits and those payments are less than the smaller of 90% of current-year tax or generally 100% of prior-year tax, subject to special rules. (IRS)

Can insufficient estimated payments create a penalty even if I later receive a refund?

Yes. The IRS states that an underpayment penalty may apply when insufficient tax was paid by a payment-period deadline even if the final return ultimately results in a refund. (IRS)

Can wage withholding be increased instead of relying solely on estimates?

Potentially yes. Employees can generally request additional withholding by filing a new Form W-4. (IRS)

What if business income is uneven throughout the year?

The annualized-income installment method may deserve review when income is received unevenly during the year. (IRS)

Final Thought

Today is payment day.

Make the payment.

Meet the obligation.

Then move forward.

Because the strongest business owners understand something important:

Quarterly deadlines should create quarterly discipline.

Your September 15 payment tells you what the first eight months created.

Your Q4 plan determines what happens next.

Maybe the business grows even faster.

Good.

Maybe profits decline.

Adjust.

Maybe a new contract closes.

Update the projection.

Maybe an investment is sold.

Include it.

Maybe you fund retirement.

Model it.

Maybe you take a large distribution.

Protect the tax reserve first.

The objective is not to perfectly predict December 31.

It is to stop operating blind.

So today's sequence should be:

Pay.

Update.

Project.

Reserve.

Strategize.

Execute.

Then repeat.

Because filing season should not be the first time you discover how successful—or expensive—the year became.

By then, the decisions are already history.

Today you still have:

time.

And time is one of the most valuable tax-planning tools available.

Your Q3 payment is due today.

But the bigger issue is what you do tomorrow.
