The Fourth-Quarter Advantage: Why the Last 90 Days Could Be Your Most Profitable

How Smart Business Owners Use the Final Months of the Year to Reduce Taxes, Increase Profits, and Build Momentum for 2027

October is here.

For many business owners, that means one thing:

The year is almost over.

They’re thinking about the holidays, wrapping up projects, collecting outstanding invoices, and perhaps squeezing in a little more revenue before December 31.

But the most successful business owners should be thinking about something else.

Opportunity.

Because the final three months of the year aren’t simply about finishing what you started.

They’re about positioning your business for what comes next.

And here’s something I want every business owner to understand:

What you do during the final 90 days of the year can have a significant impact on your taxes, profitability, cash flow, and growth opportunities for the following year.

Unfortunately, many entrepreneurs don’t realize this until January.

And by then, some of their best planning opportunities are already gone.

Let’s talk about how to avoid that mistake.

The Biggest Year-End Mistake Business Owners Make

Every year, the same thing happens.

A business owner works hard throughout the year.

Revenue comes in.

Expenses get paid.

Employees receive their paychecks.

Customers are served.

And somewhere around February or March, the owner contacts their accountant.

They hand over their financial information and ask:

“How much do I owe in taxes?”

That’s an important question.

But it’s being asked at the wrong time.

By February, the previous tax year is over.

Many decisions that could have affected the prior year’s tax liability can no longer be changed.

The business owner might discover that they could have benefited from certain retirement contributions, equipment purchases, business restructuring, or other legitimate planning opportunities.

Some tax-saving options remain available after year-end, depending on the circumstances.

But others require action before December 31.

That’s why we emphasize something at BizAccountants:

Tax preparation tells you what happened. Tax planning helps you influence what happens next.

And the fourth quarter is one of the most important times to have that conversation.

1. Know Where Your Business Actually Stands

Before making any year-end decisions, you need accurate financial information.

Not guesses.

Not estimates based on your bank balance.

Actual numbers.

Start by reviewing your year-to-date Profit & Loss Statement.

Look at your revenue.

Look at your expenses.

Look at your net profit.

Then compare those numbers to the previous year.

Ask yourself:

• Is revenue increasing?
• Are expenses growing faster than revenue?
• Are profit margins improving?
• Which expenses are unusually high?
• Are there legitimate business expenses that haven’t been recorded?
• How much profit do we expect to generate before December 31?

That last question is especially important.

Because effective tax planning requires understanding where your business is likely to finish the year.

A $200,000 Revenue Increase Doesn’t Tell the Whole Story

Imagine your business generated $600,000 last year.

This year, you’re on track to generate $800,000.

That’s fantastic.

But suppose your expenses increased from $450,000 to $680,000.

Last year:

Revenue: $600,000
Expenses: $450,000
Profit: $150,000

This year:

Revenue: $800,000
Expenses: $680,000
Profit: $120,000

You increased revenue by $200,000.

But your profit actually decreased by $30,000.

That’s not necessarily the kind of growth you want.

And it’s exactly why we spent September discussing the difference between revenue and profitability.

More sales don’t automatically create a stronger business.

Your financial statements should help you understand whether you’re actually moving forward.

2. Estimate Your 2026 Tax Liability Now

Here’s a question every profitable business owner should ask in October:

“Based on what we’ve earned so far, approximately how much are we going to owe in taxes?”

Not next April.

Now.

Your accountant should be able to use your year-to-date financial information, projected income, and other relevant details to estimate your potential tax liability.

That estimate creates opportunities.

Perhaps you need to adjust estimated tax payments.

Perhaps there are legitimate deductions you haven’t considered.

Perhaps certain business investments make sense before year-end.

Perhaps your current business structure deserves a review.

Or perhaps everything looks good and no major changes are necessary.

That’s fine too.

The objective isn’t to manufacture deductions.

The objective is to make informed decisions while you still have time to act.

Why Waiting Until April Can Be Expensive

Suppose your business is projected to generate $250,000 in taxable income.

You wait until tax season to review the numbers.

Your accountant prepares the return.

You discover a substantial tax liability.

You ask:

“Is there anything we can do to reduce it?”

Depending on your circumstances, some options may still exist.

But many decisions needed to be made during the tax year.

That’s the difference between being proactive and reactive.

The best time to discuss your 2026 tax strategy is while it’s still 2026.

3. Don’t Buy Something Just to Get a Tax Deduction

This is one of my favorite year-end conversations.

A business owner calls and says:

“I need to spend some money before December 31 so I don’t have to pay taxes on it.”

My first question is:

“What does your business actually need?”

Because spending money simply to create a deduction can be a terrible financial decision.

Let’s use a simplified example.

Suppose you spend $20,000 on equipment that qualifies for an immediate deduction.

Assume that deduction reduces your taxes by $5,000.

You’ve saved $5,000 in taxes.

But you’ve still spent $20,000.

Your business is now $15,000 behind in cash, ignoring any value the equipment provides.

If that equipment increases productivity, improves profitability, or creates additional revenue, it might be a fantastic investment.

But if you bought something you didn’t need simply to reduce your taxes?

That’s not tax planning.

That’s unnecessary spending.

The Better Question

Instead of asking:

“How much can I spend to reduce taxes?”

Ask:

“What does my business need to grow, and how can we structure that investment tax-efficiently?”

That’s how tax planning and business strategy should work together.

4. Review Your Equipment and Technology Needs

The fourth quarter is a good time to evaluate equipment and technology investments.

Maybe your business needs:

New computers.

Updated software.

Production equipment.

Office equipment.

Additional machinery.

Vehicles used for legitimate business purposes.

Automation tools.

Technology that reduces administrative work.

Certain qualifying assets may be eligible for accelerated depreciation, Section 179 expensing, or bonus depreciation.

However, the specific deduction depends on the asset, its business use, applicable limits, and current tax law.

An important distinction: Buying equipment before December 31 does not automatically make it deductible for 2026. Generally, the asset must also be placed in service during the applicable tax year.

That’s why these decisions should be reviewed before the purchase.

But remember the principle from our August series:

Every dollar should have a job.

If you’re investing $25,000 in technology, what return do you expect?

Will it save time?

Increase capacity?

Reduce payroll costs?

Improve customer service?

Generate more revenue?

Tax savings are a benefit.

The business return should be the primary reason for making the investment.

5. Take a Serious Look at Your Cash Flow

Profit and cash flow are not the same thing.

You can have a profitable business and still struggle to make payroll.

That’s particularly important during the fourth quarter.

Many businesses experience changes in cash flow during the holiday season.

Some customers slow down payments.

Some industries experience seasonal declines.

Others experience their busiest months of the year.

Meanwhile, expenses continue.

Payroll.

Rent.

Insurance.

Loan payments.

Taxes.

Vendor obligations.

Before December arrives, review your expected cash flow.

The 90-Day Cash Flow Exercise

Estimate how much money you expect to receive over the next 90 days.

Then estimate how much you expect to spend.

Include:

Payroll.

Operating expenses.

Loan payments.

Tax obligations.

Planned purchases.

Outstanding vendor balances.

Owner distributions.

Now compare the two.

If your expected cash requirements exceed available funds, you need to address that before it becomes an emergency.

Perhaps you need to improve collections.

Perhaps certain expenses can be postponed.

Perhaps your pricing needs attention.

Perhaps you need to build reserves.

Cash flow problems are easier to solve when you see them coming.

6. Review Your Accounts Receivable

Here’s an uncomfortable question:

How much money do your customers owe you right now?

Not how much revenue you’ve recorded.

How much money is actually outstanding?

If your company has $100,000 in unpaid invoices, that money isn’t helping you make payroll or invest in growth.

It’s sitting in someone else’s bank account.

October is an excellent time to review outstanding receivables.

Which invoices are more than 30 days old?

Which are more than 60 days old?

Which customers consistently pay late?

Do you have a clear collections process?

Could you improve payment terms?

Could you require deposits?

Could you automate payment reminders?

Could you accept electronic payments more easily?

Sometimes improving cash flow doesn’t require increasing revenue.

It simply requires collecting the money you’ve already earned.

One of the fastest ways to improve your financial position may be to collect what’s already owed to you.

7. Look for Expenses That Aren’t Producing Results

We’ve discussed this before, but it’s worth repeating.

Business owners often focus on increasing revenue while ignoring expenses that quietly drain profitability.

Look through your Profit & Loss Statement.

Review recurring subscriptions.

Software.

Advertising.

Professional services.

Memberships.

Unused technology.

Vendor contracts.

Ask:

“Is this expense helping our business make money, save time, reduce risk, or operate more effectively?”

If the answer is no, perhaps it deserves another look.

The $2,000 Monthly Opportunity

Imagine identifying $2,000 in unnecessary monthly expenses.

That’s:

$24,000 annually.

Now imagine redirecting that money toward something productive.

Marketing that generates profitable customers.

Technology that improves efficiency.

Training that increases employee performance.

Or simply building your cash reserves.

That’s how better financial management creates growth opportunities without requiring additional revenue.

8. Evaluate Your Business Structure

As a company grows, its business structure deserves periodic review.

The entity structure that made sense when you started may not always remain the best fit.

For example, a growing business might benefit from reviewing whether its current tax classification and legal structure continue to support its goals.

Different structures have different tax consequences, compliance requirements, administrative costs, and limitations.

At BizAccountants, we regularly emphasize the potential advantages of properly structured C corporations for certain business owners.

But a C corporation isn’t automatically the best choice for every company.

The appropriate structure depends on factors such as:

Profitability.

Ownership.

Compensation.

Distribution plans.

Reinvestment goals.

Future growth.

Exit strategy.

And the owner’s personal tax circumstances.

Changing business structures can also create significant tax consequences.

That’s why restructuring should never be done simply because someone heard that one entity type pays a lower federal tax rate.

Your business structure should support your business strategy.

And October is a good time to begin evaluating whether changes might make sense for the following year.

9. Start Planning Your 2027 Growth Strategy

Now let’s move beyond taxes.

Because the fourth quarter isn’t only about finishing 2026.

It’s also about preparing for 2027.

Remember our September series?

We discussed building the infrastructure required to grow from $100,000 toward $1 million.

That doesn’t happen accidentally.

It requires planning.

So here’s what I want you to do.

Imagine it’s December 31, 2027.

You’re looking back at an incredibly successful year.

What happened?

Did you increase revenue?

Improve profit margins?

Hire key employees?

Launch a new service?

Expand into another market?

Reduce debt?

Improve cash flow?

Build better systems?

Take more time away from the business?

Now work backward.

What would you need to begin doing today to make those results possible?

That’s where fourth-quarter planning becomes powerful.

You’re not simply closing out a year.

You’re building the foundation for the next one.

10. Create Your 2027 Financial Targets

Most business owners have goals.

But goals without numbers are difficult to manage.

Instead of saying:

“I want to grow next year.”

Get specific.

Suppose your company expects to finish 2026 with:

Revenue: $500,000
Net Profit: $75,000
Profit Margin: 15%

Now suppose your 2027 goal is:

Revenue: $650,000
Net Profit: $130,000
Profit Margin: 20%

That’s a meaningful improvement.

But here’s the important part.

You don’t simply want another $150,000 in revenue.

You want to generate that additional revenue while improving profitability.

That requires understanding what will change.

Will you raise prices?

Improve efficiency?

Reduce overhead?

Increase employee productivity?

Focus on more profitable services?

Improve marketing performance?

Every goal should have a strategy behind it.

Otherwise, it’s just a number on a piece of paper.

11. Don’t Confuse Being Busy With Making Progress

October can be a hectic month.

There are customers to serve.

Projects to finish.

Employees to manage.

Deadlines to meet.

And dozens of other things demanding your attention.

It’s easy to get so busy running the business that you never spend time improving it.

But think about this.

If you spend the next 90 days doing exactly what you’ve done for the previous nine months, why should you expect dramatically different results next year?

Sometimes the most valuable thing you can do isn’t another customer appointment.

It isn’t another sales call.

It isn’t answering another email.

It’s sitting down with your financial information and asking:

“What needs to change?”

That question can be worth far more than another hour of routine work.

12. Schedule a Fourth-Quarter Business Strategy Meeting

Here’s something I strongly recommend.

Before November is over, schedule a dedicated business strategy meeting.

Not simply a tax preparation appointment.

A strategy meeting.

Ideally, you should review both your financial performance and your plans for the future.

The discussion should include your projected year-end profit, estimated tax liability, cash flow, planned purchases, business structure, and goals for 2027.

You should leave the meeting understanding three things:

1. Where your business stands today.
2. What opportunities may still exist before December 31.
3. What needs to happen to make next year better.

That’s a much more valuable conversation than simply asking how much you owe in taxes after the year is over.

The Fourth-Quarter Business Owner’s Challenge

I want to leave you with a challenge.

Before October ends, answer these five questions:

1. How much profit is my business projected to generate in 2026?

If you don’t know, that’s the first thing to address.

2. What is my estimated 2026 tax liability?

Don’t wait until April to find out.

3. What is the single biggest financial problem in my business?

Cash flow? Margins? Overhead? Collections? Something else?

4. What investment could make my business stronger in 2027?

Marketing? People? Technology? Systems? Training?

5. What would make 2027 my most profitable year yet?

Be specific.

Because here’s something worth remembering:

The businesses that finish strong usually aren’t waiting until January to start planning for success.

They’re doing it now.

Final Thoughts: The Year Isn’t Over Yet

There’s a tendency to mentally check out during the final quarter.

The year is almost finished.

The holidays are approaching.

Maybe business has been difficult.

Maybe you’ve had an incredible year.

Either way, it’s tempting to simply coast toward December 31.

But I want to challenge that thinking.

You still have time to make meaningful decisions.

Time to improve your financial position.

Time to evaluate legitimate tax-saving opportunities.

Time to strengthen cash flow.

Time to eliminate unnecessary expenses.

Time to make strategic investments.

And time to prepare for a better 2027.

The fourth quarter shouldn’t simply be about finishing the year.

It should be about creating an advantage for the next one.

Because the business owners who make the most of these final months aren’t simply closing the books.

They’re opening the door to what’s next.

Don’t Wait Until Tax Season to Discover What You Could Have Done

At BizAccountants, we believe business owners deserve more than someone who simply prepares their tax returns.

They deserve a financial strategy.

That’s why we combine proactive tax planning, bookkeeping, tax preparation, payroll support, and business growth guidance to help entrepreneurs make better decisions throughout the year.

Our goal isn’t simply to tell you how much you owe.

It’s to help you understand how much you can legally keep—and how to put that money to work building a stronger business.

2026 isn’t over. Your opportunities shouldn’t be either.

If you haven’t reviewed your projected 2026 tax liability or started planning for 2027, now is the time.
