Running a business keeps you busy. Between serving customers, managing expenses, and trying to grow, it's easy to put your finances on the back burner.
But here's something I want every small business owner to understand: What you do before December 31 can make a difference when it's time to file your taxes.
And no, I'm not talking about rushing out to buy things you don't need just to get a tax deduction.
I'm talking about understanding where your business stands, getting your records in order, and making smart decisions while you still have time.
Whether you're a freelancer, independent contractor, or small business owner, here are 10 things worth reviewing before 2026 comes to an end.
1. Get Your Bookkeeping Up to Date
Let's start with something simple.
Do you know how much money came into your business this year? How much went out? And where it all went?
If your bookkeeping hasn't been updated in months, now is the time to catch up.
Review your business bank statements, credit card transactions, invoices, and receipts. Make sure your income and expenses are recorded correctly.
Pay special attention to transactions that may have been missed or recorded twice.
Remember: Good bookkeeping isn't just about preparing for taxes. It helps you understand how your business is performing throughout the year.
2. Find Out How Much Profit You Actually Made
One thing I've noticed over the years is that business owners sometimes focus so much on how much money they're bringing in that they overlook how much they're keeping.
Making $100,000 in sales doesn't mean you made $100,000 in profit.
If your business brought in $100,000 but had $65,000 in expenses, your profit before other adjustments is $35,000.
That's a very different financial picture.
Take a look at your profit-and-loss statement. Compare your income against your expenses and see what's left.
This information can help you make better decisions about pricing, spending, and preparing for taxes.
Your revenue tells you how much business you did. Your profit tells you more about how the business is doing.
3. Review Business Expenses You May Have Missed
It's easy to forget about smaller business expenses, especially when you're paying for things throughout the year.
Take some time to review expenses such as:
Software and monthly subscriptions
Office supplies and equipment
Business-related mileage
Advertising and marketing
Professional services
Business insurance
Eligible home office expenses
You may discover expenses that were never entered into your bookkeeping records.
Just remember, not every expense qualifies as a tax deduction. Generally, it must be ordinary and necessary for your business, and some expenses have additional rules.
The goal isn't to claim everything. It's to make sure you're not overlooking legitimate business expenses.
4. Think Before Making Last-Minute Business Purchases
Every December, business owners start asking whether they should buy equipment, computers, or other items before the year ends.
Sometimes making a purchase before December 31 makes sense.
Other times, it doesn't.
Here's what I want you to remember:
Spending $2,000 to save a portion of that amount in taxes still means you spent $2,000.
If your business genuinely needs new equipment, this may be a good time to review the purchase. Certain qualifying equipment may be eligible for accelerated tax deductions, depending on the rules and your circumstances.
But don't let the possibility of a deduction convince you to spend money your business needs for something else.
A smart tax decision should also make financial sense.
5. Check Your Estimated Tax Payments
If you're self-employed, taxes usually aren't automatically taken out of your business income.
That means you may need to make estimated tax payments throughout the year.
Before December ends, review how much you've earned, how much you've already paid, and whether your payments are keeping up with your income.
For most calendar-year individual taxpayers, the final estimated tax payment for 2026 is due January 15, 2027.
If your income increased significantly this year, the payments you made earlier may not be enough.
And if you also have a W-2 job, your paycheck withholding may affect how much you need to pay separately.
Don't wait until you file your return to find out whether you've set aside enough money.
6. Review Retirement and Other Tax-Saving Opportunities
Have you considered whether your business income could help you save for retirement?
Depending on your situation, options such as a SEP IRA or Solo 401(k) may allow you to put money toward retirement while receiving certain tax benefits.
These plans have different eligibility requirements, contribution limits, and deadlines.
Some decisions need to happen before year-end, while others may still be available when you prepare your tax return.
The important thing is to review your options instead of assuming you've missed your opportunity.
And remember, reducing taxes today shouldn't come at the expense of money you need to operate your business.
7. Get Your Contractor and Employee Records Ready
If you paid independent contractors during 2026, now is a good time to review those payments.
Make sure you have completed W-9 forms when appropriate, accurate payment records, and current contact information.
For 2026 payments, the federal Form 1099-NEC reporting threshold generally increased to $2,000 for qualifying payments to a contractor, subject to reporting exceptions and payment-method rules.
If you have employees, review payroll records and make sure wages, payroll taxes, and employee information are accurate.
S corporation owners should also review whether their payroll and compensation arrangements have been handled properly.
Taking care of these details now can help you avoid unnecessary headaches when January arrives.
8. Stop Mixing Business and Personal Money
If you've been using the same account for business purchases, groceries, subscriptions, and personal expenses, it's time to get organized.
Mixing business and personal transactions makes bookkeeping harder than it needs to be.
It can also make it more difficult to identify legitimate business expenses.
Review your transactions and make sure personal purchases aren't being treated as business deductions.
If you're operating a business, having a separate business bank account can make managing your money much easier.
You don't need a complicated system. You need one that helps you clearly see what's happening with your money.
9. Review Whether Your Business Structure Still Makes Sense
The business you started two or three years ago may look very different today.
Maybe your income has increased.
Maybe you've hired employees.
Or maybe you're operating as a sole proprietor or single-member LLC and wondering whether an S corporation would make sense.
These are conversations worth having before making changes.
But here's something important: An LLC doesn't automatically lower your taxes, and an S corporation isn't the right move for every business owner.
Your income, expenses, payroll responsibilities, and long-term goals all matter.
Before changing your business structure, make sure you understand both the potential benefits and the additional responsibilities.
10. Make a Simple Financial Plan for 2027
Before you close out the year, spend a little time looking ahead.
Ask yourself:
Did my business make the profit I expected?
Am I charging enough for my services?
Which expenses can I reduce?
Do I have enough money set aside for taxes?
What do I want to improve next year?
You don't need a 30-page business plan.
Start with two or three realistic goals and identify what needs to change to reach them.
Maybe it's raising your prices, improving your bookkeeping, building a cash reserve, or getting professional guidance earlier in the year.
The important thing is to enter 2027 with a clearer understanding of where you're going.

Frequently Asked Questions
What should a small business owner do before December 31?
Start by reviewing your bookkeeping, income, expenses, and estimated tax payments. You should also check contractor records, consider any time-sensitive tax planning opportunities, and prepare a simple financial plan for the coming year.
Can I still reduce my 2026 business taxes before the year ends?
Possibly. Depending on your circumstances, there may be opportunities involving eligible business expenses, equipment purchases, retirement contributions, and other tax planning strategies.
However, not every strategy works for every business. It's important to understand how a decision affects your overall finances before taking action.
What happens if I haven't paid enough estimated taxes for 2026?
You may owe additional taxes when you file your return, and underpayment penalties may apply.
For most calendar-year individual taxpayers, the final 2026 estimated tax payment is due January 15, 2027. Reviewing your numbers now can help you understand whether an additional payment may be necessary.
Don't Wait Until Tax Season to Find Out Where You Stand
After nearly 20 years of working with taxpayers and business owners, one thing I've seen repeatedly is how often people wait until tax season to find out what's happening with their finances.
By then, some opportunities have already passed.
That's why I encourage business owners to think beyond simply filing a tax return.
Tax preparation helps you report what happened.
Tax planning helps you make better decisions before the year is over.
You don't have to know every tax rule or figure everything out on your own. But you should understand enough about your business to recognize when it's time to ask questions and make changes.
And sometimes, the smartest thing you can do before December 31 is simply get organized.
