Maximizing Your Solo Business Tax Strategy Before Year-End
With roughly two months remaining in the 2026 tax year, solo entrepreneurs have a valuable opportunity to optimize their tax situation before December 31 locks in many financial decisions. For many founders running one-person businesses, this late-year window can significantly impact their tax bill, yet it often goes underutilized. This period allows you to strategically time purchases, contribute to retirement accounts, finalize contractor paperwork, and ensure you’re not facing unexpected penalties for underpayment.
The 2026 tax year is especially noteworthy due to the sweeping changes introduced by the Working Families Tax Cuts—a law enacted on July 4, 2025, that has redefined key provisions affecting solo founders, freelancers, and small online businesses. Several provisions take effect for payments made in 2026, meaning this year-end planning is more critical than ever. While this article offers a practical framework for year-end tax moves tailored for U.S.-based solo operators, individual circumstances such as entity type, income level, and state tax laws require personalized advice from a professional accountant.
Start by Closing Your Books Thoroughly
Effective tax planning begins with a clear understanding of your current financial standing. Before making any purchases or retirement contributions, ensure your accounting is up to date at least through October. This involves reconciling all business bank and credit card accounts, categorizing any unclassified transactions, and collecting receipts for significant expenses. From there, develop a realistic projection for November and December based on signed contracts, expected invoices, and known upcoming costs.
This projection provides an estimated profit figure for the year, which is foundational for all subsequent tax planning decisions. For example, a profitable year offers different opportunities compared to a slower year. Misestimating this figure can lead to unnecessary spending with no real tax benefit or missed opportunities for tax savings, such as neglecting eligible retirement contributions.

Review Your Estimated Tax Payments Now, Not Next April
Since most solo entrepreneurs lack employer withholding, they bear full responsibility for making estimated tax payments throughout the year. According to the IRS’s estimated taxes guidance, taxpayers generally avoid penalties if they owe less than $1,000 after withholdings and credits or have paid at least 90% of the current year’s tax or 100% of the previous year’s tax, whichever is smaller. Higher-income taxpayers may face different thresholds, so it is essential to verify your applicable rules.
Running the numbers against your year-end projection now allows you to identify any underpayments while there is still time to act. If your income accelerated during the year, your earlier quarterly payments might be insufficient. The final estimated tax payment is your chance to bridge that gap and avoid penalties. Conversely, if you find you’ve overpaid, you can reallocate funds back into your business or investments. Timely assessment is far preferable to surprises during tax filing season.
Strategically Time Equipment Purchases
The new tax law has reinstated full expensing for many business assets, providing a significant tax advantage. The IRS confirms that for qualified property acquired after January 19, 2025, businesses can claim a permanent 100% additional first-year depreciation deduction—commonly referred to as bonus depreciation. Furthermore, the Section 179 expensing limit has increased to $2,500,000 for property placed in service after December 31, 2024, with inflation adjustments anticipated in subsequent years.
For solo businesses, this means that if you plan to acquire equipment such as computers, cameras, or studio gear, placing these assets into service before year-end accelerates the deduction into the 2026 tax year instead of depreciating the cost over several years. However, as the IRS’s guidance for gig economy workers highlights, business use must exceed 50% for certain types of property to qualify for the full first-year deduction.
It’s crucial to emphasize buying only what your business genuinely needs. Spending money solely to reduce taxes is counterproductive. Keep detailed records of purchase dates and when assets were first used, and consult your accountant to determine whether immediate expensing or gradual depreciation aligns best with your tax strategy.
Leverage Retirement Plan Contributions
Retirement plans often represent the single most powerful tax and wealth-building tool available to solo founders. For 2026, the IRS has increased contribution limits substantially: the 401(k) elective deferral limit rises to $24,500; catch-up contributions for those aged 50 and over increase to $8,000; and a special catch-up limit of $11,250 applies for individuals aged 60 to 63. IRA contribution limits also increase to $7,500, with total defined contribution plan limits set at $72,000.
One-person businesses can contribute both as employees and employers. In a one-participant 401(k) plan, the owner can make elective deferrals and employer nonelective contributions, subject to IRS limits and specific self-employment calculations. Alternatively, a Simplified Employee Pension (SEP) plan offers a straightforward option, allowing contributions up to 25% of compensation and can be established as late as the business tax return filing deadline, including extensions, per the IRS’s SEP guidelines.
Because retirement plan deadlines and paperwork vary by plan type, it’s wise not to postpone discussions with your plan provider or accountant until December’s final days. Early November is an ideal time to evaluate options, set up plans, and make contributions. Building disciplined saving habits now can profoundly influence your long-term financial success and entrepreneurial journey (source).
Prepare Contractor Paperwork Ahead of Time
If you engage freelancers, designers, or other contractors, be aware of key changes in reporting requirements. The IRS has increased the Form 1099-NEC reporting threshold to $2,000 for payments made in 2026—up from the longstanding $600 threshold—with inflation adjustments beginning in 2027 (source).
This higher threshold means some smaller contractor payments no longer require 1099-NEC forms, reducing administrative burden. However, you must still track total payments accurately and file 1099-NECs for any contractors from whom you withheld federal income tax under backup withholding rules, regardless of payment amount.
Smart year-end tax practice includes generating payee reports now, collecting outstanding W-9 forms while contractors are responsive, and correcting any errors in names or tax IDs before the January filing rush. If you’ve automated contract and payment workflows (learn more), integrate W-9 collection into onboarding to simplify future compliance.
Understand What Payment Platforms Will Report
Many small online businesses receive payments through third-party apps and marketplaces, which are subject to specific IRS reporting rules. The law has retroactively restored the Form 1099-K reporting threshold for third-party settlement organizations to $20,000 in payments and 200 transactions annually. This is a significant increase from previous lower thresholds.
Crucially, the IRS stresses that all income must be reported on your tax return—regardless of whether you receive a 1099-K or any other information return. The raised threshold merely changes the paperwork you receive, not your actual tax liability. Therefore, maintaining comprehensive records of all revenue streams, including those from smaller platforms that may not issue forms, is essential to ensure accurate tax reporting.
Don’t Overlook the Qualified Business Income Deduction
The Qualified Business Income (QBI) deduction, available to many sole proprietors, partnerships, and S corporations since 2018, remains a critical tax benefit and has been made permanent by the new tax law. This deduction allows eligible taxpayers to deduct up to 20% of their qualified business income, subject to various limitations. Importantly, it applies regardless of whether you itemize deductions or take the standard deduction.
For tax years after 2025, a new minimum deduction applies for active qualified business income. Income from C corporations or wages earned as an employee don’t qualify. The amount of the QBI deduction depends on your taxable income, business type, wages paid, and property held, making it essential to include this in your year-end tax planning discussions.
Decisions about retirement contributions, equipment purchases, and income projections all affect your taxable income and, consequently, your ability to maximize this deduction. Collaborate with your accountant to ensure you’re leveraging the QBI deduction effectively.
Set Up Your 2027 Tax System Now
Perhaps the most valuable year-end tax move is preparing next year’s tax process to be smooth and manageable. If you haven’t done so, open a separate tax savings account and deposit a fixed percentage of every payment you receive to cover quarterly estimated taxes. Mark your calendar with payment due dates to avoid penalties.
Choose a bookkeeping system that suits your business and commit to monthly reconciliations rather than scrambling to organize your finances each December. Scheduling a mid-year planning session with your accountant in 2027 can provide actionable insights while there’s still time to implement changes before year-end.
While these steps may not seem glamorous, they cultivate the discipline that separates businesses that grow strategically from those constantly caught off guard by their own financials. A few focused hours on year-end tax planning now, coupled with professional advice, will position you for more cash flow, fewer surprises, and a clearer understanding of your business’s true earnings in 2027.
