2026 Year-End Tax Planning for Tampa Businesses: 12 Moves to Make Before December 31

For Tampa business owners, entrepreneurs, independent contractors, and self-employed professionals, one of the biggest tax mistakes is waiting until tax season to start thinking about taxes.
By the time your CPA prepares your return, most of the year is already over—and many of the decisions that could have reduced your tax liability can no longer be changed.
That is why late summer and early fall can be one of the most important times of the year for tax planning.
With several months remaining in 2026, Tampa Bay business owners still have time to review income, expenses, estimated taxes, retirement contributions, equipment purchases, business structure, and other strategies that may reduce their overall tax burden.
Here are 12 tax-planning areas worth reviewing before December 31.
1. Project Your 2026 Income Before the Fourth Quarter
Effective tax planning starts with knowing approximately where you will finish the year.
Business owners should review year-to-date revenue and expenses and develop a realistic projection for the remainder of 2026.
That projection can help estimate your taxable business income, personal income, potential tax bracket, and the amount of tax you may owe.
This is particularly important if your business has experienced significant growth, unusually high profits, a large contract, the sale of an asset, or another event that could substantially increase your taxable income.
A CPA can use these projections to identify tax-planning opportunities while there is still time to act.
2. Review Your September 15 Estimated Tax Payment
Many business owners, self-employed individuals, investors, and taxpayers with income that is not subject to sufficient withholding are required to make estimated tax payments during the year.
For 2026, the third estimated tax installment is due September 15.
Simply paying the same amount you paid last quarter may not always be the best strategy.
If your income has increased significantly during 2026, your estimated payments may need to increase as well. On the other hand, if business has slowed or your circumstances have changed, your projected tax liability may be different than originally anticipated.
Underpaying estimated taxes can potentially lead to penalties, making this an ideal time to have your CPA review your year-to-date numbers.
3. Don’t Confuse Tax Preparation With Tax Planning
Tax preparation and tax planning are two very different services.
Tax preparation primarily reports what already happened.
Tax planning looks forward.
A tax return prepared in March or April generally documents transactions and decisions that occurred during the previous year. By that point, many potential tax strategies are no longer available.
Proactive tax planning gives you an opportunity to evaluate decisions before December 31.
For business owners, that may include the timing of purchases, compensation, retirement contributions, investments, charitable giving, deductions, and other financial decisions.
The earlier those conversations occur, the more options you may have.
4. Review Whether Your Business Structure Still Makes Sense
As businesses grow, the tax structure that made sense when the company was created may no longer be the most efficient structure.
For example, a business operating as a sole proprietorship or single-member LLC may eventually want to evaluate whether an S corporation election could make sense.
An existing S corporation should also periodically review shareholder compensation, payroll, distributions, and compliance requirements.
Entity selection should never be based solely on one potential tax deduction. Legal liability, payroll requirements, administrative costs, state taxes, future growth, ownership structure, and other factors should also be considered.
However, if your Tampa business has grown substantially during the past year, now may be a good time to ask your CPA whether your current entity and tax structure remain appropriate.
5. Evaluate Major Equipment and Technology Purchases
If your business is already planning to purchase equipment, computers, machinery, furniture, technology, or other qualifying business assets, the timing of those purchases can have important tax consequences.
Recent federal tax legislation restored permanent 100% additional first-year depreciation for certain qualified property acquired after January 19, 2025. Federal law also significantly increased the Section 179 expensing limitation beginning with tax years after 2024, subject to eligibility requirements and limitations.
That does not mean a business should purchase something simply to receive a tax deduction.
Spending $100 solely to save a portion of that amount in taxes is rarely a good business strategy.
But if your company already needs a vehicle, piece of equipment, computer system, machinery, or other capital asset, discussing the purchase with your CPA before year-end can help determine the most advantageous timing and tax treatment.
6. Review Retirement Plan Opportunities
Retirement planning can be one of the most powerful tools available to business owners.
Depending on the business and number of employees, options may include a:
- 401(k)
- Solo 401(k)
- SEP IRA
- SIMPLE IRA
- Profit-sharing plan
- Cash balance or defined-benefit plan
Different plans have different contribution limits, deadlines, administrative requirements, and eligibility rules.
For highly profitable businesses, retirement-plan design can sometimes provide substantial tax advantages while helping the owner and employees build long-term wealth.
Business owners who wait until tax filing season may discover that some planning opportunities required action earlier.
If retirement contributions are part of your 2026 tax strategy, discuss them with your CPA and financial advisor before the end of the year.
7. Review the Timing of Income and Expenses
Depending on your accounting method and individual circumstances, the timing of income and deductible expenses can affect taxable income.
A business expecting significantly higher income this year than next year, for example, may want to discuss whether there are legitimate opportunities to accelerate certain deductible expenses.
Another business expecting much higher income next year could have a completely different strategy.
There is no universal rule that businesses should simply “push income into next year.”
Tax planning should consider multiple years.
The goal is generally to determine when income and deductions can be recognized most efficiently while complying with federal tax law.
8. Examine Accounts Receivable and Outstanding Business Expenses
The final months of the year are also an excellent time to review your company’s balance sheet.
Business owners should look carefully at outstanding accounts receivable, unpaid invoices, business debts, obsolete inventory, outstanding expenses, and potentially uncollectible accounts.
This review can serve two purposes.
First, it can improve your understanding of the company’s true financial condition.
Second, some items may have tax implications depending on your accounting method and circumstances.
A good year-end review with your CPA should involve more than looking at your profit-and-loss statement. The balance sheet can reveal important issues that deserve attention before tax season.
9. Review Your Business Vehicle and Mileage Records
Vehicle deductions continue to be an area where business owners can lose legitimate deductions because their records are incomplete.
If you use a vehicle for business, make sure your mileage records and supporting documentation are being maintained throughout the year.
Trying to reconstruct an entire year’s worth of business mileage months later is difficult and can lead to inaccurate records.
Business owners purchasing vehicles should also talk with their CPA before assuming a vehicle will automatically qualify for a particular deduction.
The tax treatment can depend on the vehicle, its weight, percentage of business use, purchase structure, and other factors.
10. Prepare for 1099 and Payroll Reporting Now
January reporting deadlines arrive quickly.
Rather than waiting until January to discover that your business is missing information from contractors or vendors, review your records during the fall.
Make sure appropriate Form W-9 information is being collected and your accounting system accurately identifies payments that may be subject to information-reporting requirements.
Employers should also review payroll records, employee information, fringe benefits, shareholder health insurance where applicable, retirement contributions, and other year-end payroll items.
Cleaning up these records before December can make January much easier.
11. Review Capital Gains, Investments, and Major Transactions
Business owners often have taxable income outside of their businesses.
That may include stocks, real estate, cryptocurrency, partnership interests, rental properties, or other investments.
If you have realized significant capital gains during 2026, tax planning should consider those gains along with your business income.
In certain situations, taxpayers may also have investments with unrealized losses that should be discussed with their investment and tax advisors as part of an overall year-end strategy.
Major transactions deserve particular attention.
If you are considering selling a business, property, investment, or other valuable asset, discussing the tax consequences before the transaction closes can be significantly more valuable than discussing them afterward.
12. Schedule Your Year-End Tax Planning Meeting Before December
Perhaps the most important tax-planning move is also the simplest:
Talk with your CPA before the year is over.
November and December can become extremely busy for accounting firms, financial advisors, attorneys, and business owners.
Starting your planning in September or October provides more time to analyze your financial position and implement recommendations.
A productive tax-planning meeting may include reviewing:
- Year-to-date business income and expenses
- Projected 2026 taxable income
- Estimated tax payments
- Payroll and owner compensation
- Business entity structure
- Retirement contributions
- Equipment purchases
- Capital gains and investment income
- Charitable contributions
- Business deductions
- Major planned transactions
- Expected changes in 2027
The objective is not simply to find deductions.
It is to develop a coordinated strategy based on your business, income, goals, cash flow, and long-term financial plans.
Why Tampa Business Owners Should Start Tax Planning Now
Tampa Bay continues to be home to a growing community of entrepreneurs, professional practices, contractors, real estate investors, consultants, family businesses, and privately held companies.
As income and businesses grow, tax situations generally become more complicated.
Waiting until tax season can turn the relationship with your CPA into a once-a-year exercise focused primarily on filing forms.
A proactive relationship is different.
Your CPA can help you understand what your numbers are telling you throughout the year and identify opportunities before important deadlines pass.
For many business owners, the question should not simply be:
“How much do I owe?”
The better question is:
“What can I legally and strategically do before December 31 to improve my tax position?”
That is the purpose of year-end tax planning.
Don’t Wait Until Tax Season to Find Out What You Could Have Done
Once December 31 passes, many financial decisions affecting your 2026 taxes will already have been made.
If your business has grown, your income has changed, you have made or are considering a major purchase, or you simply want a clearer picture of your expected tax liability, now is the time to start planning.
CPA Tampa works with Tampa Bay businesses and individuals to evaluate their tax position before year-end and develop strategies tailored to their specific circumstances.
Rather than waiting until your return is prepared to discover what you owe, take the opportunity to plan while there is still time to make informed decisions.
