Maximizing Year-End Tax Strategies for One-Person Businesses in 2026
With roughly two months left in the 2026 tax year, solo entrepreneurs have a critical window to optimize their tax positions. Once December 31 passes, many tax-affecting decisions become irreversible. This period offers valuable opportunities to time purchases, fund retirement accounts, organize contractor paperwork, and avoid penalties related to underpayment of taxes throughout the year. Understanding these moves can significantly impact your tax liability and long-term financial health.
The 2026 tax year also brings notable changes following the enactment of the Working Families Tax Cuts, signed into law on July 4, 2025. Often referred to as the One Big Beautiful Bill, this legislation has altered several tax provisions critical to solo founders, freelancers, and small online businesses. Some provisions take effect for the first time in 2026, making it essential for US-based solo operators to understand how these shifts affect their tax planning. While this article provides a structured approach to year-end tax considerations, consulting with a qualified accountant remains indispensable as individual circumstances vary widely based on entity type, income level, and state regulations.
Close Your Books Before Making Any Moves
Accurate financial data forms the foundation of any effective year-end tax strategy. Before purchasing equipment or contributing to retirement plans, ensure your accounting records are up to date through October. This includes reconciling all business bank and credit card accounts, categorizing pending transactions, and gathering receipts for significant expenses. Creating a detailed projection for November and December—based on signed contracts, expected invoices, and known costs—provides an estimated profit figure that guides all subsequent decisions.
Knowing your estimated annual profit helps prevent common missteps, such as buying unnecessary equipment to reduce taxes or missing out on retirement contributions that could have been made.

Review Estimated Tax Payments Now
Since most solo entrepreneurs lack employer tax withholding, they must manage estimated tax payments themselves. According to the IRS’s estimated taxes page, taxpayers typically avoid underpayment penalties if they owe less than $1,000 after credits and withholding, or if they have paid at least 90% of the current year’s tax liability or 100% of the previous year’s tax—whichever is less. Special rules apply for higher earners, so understanding your applicable threshold is critical.
Compare your projected income against your quarterly payments now. If your revenue increased during the year, your earlier payments might have been insufficient, making the final payment an opportunity to close any gaps. Identifying a shortfall before year-end allows you to set aside funds and avoid penalties. Conversely, if you have overpaid, you can allocate excess funds back into your business. Addressing these matters in October is far preferable to discovering them during tax filing season.
Time Equipment Purchases to Optimize Deductions
The 2025 tax reforms reintroduced full expensing for many business assets, providing a powerful tool for solo businesses. The IRS confirms a permanent 100% additional first-year depreciation deduction—often called bonus depreciation—for qualifying property acquired after January 19, 2025. Additionally, the Section 179 expensing limit was raised to $2,500,000 for property placed in service after December 31, 2024, with inflation adjustments expected in future years.
Practically, if you plan to purchase computers, cameras, studio gear, or similar qualifying equipment, acquiring and placing these assets into service before year-end can accelerate deductions into your 2026 tax return instead of depreciating over several years. The IRS’s guidance for gig economy workers highlights that for certain assets like vehicles or specific computers, business use must exceed 50% to qualify for full first-year expensing on the business-use percentage.
It’s crucial to only purchase what your business genuinely needs—tax savings do not justify unnecessary expenditures. Maintain detailed records of purchase dates and service commencement, and collaborate with your accountant to determine whether expensing immediately or depreciating over time aligns best with your financial goals.
Leverage Retirement Plan Contributions
For profitable solo entrepreneurs, retirement plans often represent the most impactful tax-saving mechanism while simultaneously building wealth. The IRS announced that for 2026, the 401(k) elective deferral limit increased to $24,500, catch-up contributions rose to $8,000 for those aged 50 and over, and an enhanced catch-up of $11,250 applies for ages 60 to 63. IRA contribution limits increased to $7,500, and the overall ceiling for defined contribution plans reached $72,000.
Solo business owners can contribute both as employees and employers. The IRS explains that in a one-participant 401(k) plan, the owner can make elective deferrals plus employer nonelective contributions, subject to overall limits and specific self-employed calculation rules. A SEP IRA offers a simpler alternative, allowing contributions up to 25% of compensation, and can be established as late as the tax return due date, including extensions, per IRS guidelines on SEP plans.
Because deadlines and paperwork vary by plan type, begin discussions with your plan provider or accountant by November. This proactive approach ensures you meet year-end requirements and maximize contributions. Developing consistent retirement saving habits greatly influences both your business’s trajectory and your personal financial success—a connection explored further here.
Prepare Contractor Paperwork Early
If you engage freelancers, designers, or developers, the new law raises the Form 1099-NEC filing threshold to $2,000 for payments made in 2026, up from the long-standing $600 limit. This threshold will be inflation-adjusted starting in 2027, potentially reducing paperwork for smaller contractors.
However, maintain diligence: a 1099-NEC is still required for any contractor from whom you withheld federal income tax under backup withholding rules, regardless of payment amount. The best year-end practice is to generate a payee report now, collect any missing W-9 forms while contractors are responsive, and correct incomplete or inaccurate information before the busy January filing period. If you have systems in place for managing contracts and payments—such as those described here—incorporate W-9 collection into onboarding to streamline compliance in future years.
Understand Payment Platform Reporting Requirements
Many online businesses receive payments via apps or marketplaces, subject to evolving reporting rules. The IRS notes that the law retroactively restored the Form 1099-K reporting threshold for third-party settlement organizations to $20,000 in gross payments and 200 transactions annually, reversing a temporary lower threshold.
Importantly, receiving a 1099-K or any information return does not affect your obligation to report all income. Even if you do not receive a form, all earnings must be reported when filing. Ensure your records capture every revenue stream, including smaller platforms that may never issue tax forms, so your tax return accurately reflects your business’s true income.
Don’t Overlook the Qualified Business Income Deduction
The qualified business income (QBI) deduction, available since 2018 for eligible sole proprietorships, partnerships, and S corporations, has been made permanent by the new law. The IRS explains that it allows qualifying taxpayers to deduct up to 20% of their qualified business income, subject to various limitations. This deduction applies whether you itemize deductions or claim the standard deduction. For tax years beginning after 2025, a new minimum deduction applies for active qualified business income. Income earned as a C corporation or as an employee is excluded.
The QBI deduction’s value depends on taxable income, business type, wages paid, and property owned, especially for higher earners. Because your year-end projections, retirement contributions, and equipment purchases affect taxable income, they also influence your QBI deduction. Engaging your accountant early to integrate these factors into your tax planning avoids surprises when filing.
Set Up for a Smooth 2027 Tax Year
The most effective year-end tax move is preparing for a less stressful next year. Open a dedicated tax savings account if you don’t already have one, and consistently transfer a fixed percentage of every payment received into it. Mark quarterly estimated tax payment due dates on your calendar and select bookkeeping software that supports monthly reconciliations rather than last-minute annual reviews. Schedule a mid-2027 planning session with your accountant to review progress and adjust strategies as needed.
While these steps may lack glamour, cultivating disciplined financial habits distinguishes businesses that grow with intention from those frequently blindsided by their own numbers. Investing a few focused hours on these year-end tax moves, armed with accurate projections and questions, will position you for more cash flow, fewer surprises, and a clearer understanding of your business’s true profitability in 2027.
