Year-End Tax Planning 2026: 7 Moves Business Owners Must Make Before December 31

September 30, 2026

December 31, 2026, is more than a calendar date.

It is a planning deadline.

Business owners who wait until tax season often discover that their best opportunities have already passed. Equipment was not placed in service. Retirement contributions were not structured correctly. Estimated payments were too low. Entity decisions were postponed.

Do not wait.

“Your year-end tax plan should be decided before the year ends, not after the tax return is prepared.”

These seven moves help business owners control taxable income, preserve deductions, and build a stronger financial plan for 2027.

1. Control the Timing of Income and Deductions

Your taxable income does not happen by accident. Timing matters.

Review your projected 2026 income now. Then decide whether accelerating or deferring certain income and deductions creates the better result.

Depending on your accounting method, cash flow, and tax bracket, you may consider:

  • Collecting certain invoices before year-end
  • Deferring eligible revenue until January
  • Paying deductible expenses before December 31
  • Delaying discretionary purchases until 2027
  • Reviewing year-end bonuses and owner compensation
  • Prepaying certain business expenses when permitted

The goal is not simply to create the largest possible deduction. The goal is to manage your entire tax picture.

A deduction that lowers qualified business income may also reduce the value of the 20% QBI deduction. A large expense may create a loss that cannot be used immediately. A bonus may affect payroll taxes, retirement contributions, and future cash flow.

Model the full outcome before making the move.

2. Use 100% Bonus Depreciation and Section 179 Strategically

The 2026 tax year creates a major equipment-planning opportunity.

Under the current 2026 planning framework, qualifying property placed in service by December 31 may qualify for 100% bonus depreciation. The provision is scheduled to change after 12/31/2026, so business owners should not assume the same treatment continues into 2027.

Potentially qualifying property may include:

  • Machinery and equipment
  • Computers and technology
  • Furniture
  • Certain business vehicles
  • Certain software
  • Other eligible property with a qualifying recovery period

The key phrase is placed in service.

Ordering an item is not always enough. The property generally needs to be delivered, installed, and ready for business use before the deadline.

Also evaluate Section 179 expensing. Section 179 may allow qualifying equipment and software to be expensed immediately, subject to annual limits, taxable-income restrictions, and phase-out rules.

Do not automatically choose one method.

Compare:

  • 100% bonus depreciation
  • Section 179 expensing
  • Regular depreciation over time
  • Federal and state conformity rules
  • The effect on QBI
  • The effect on current and future tax brackets

The IRS explains depreciation rules in Publication 946 and provides election details through the Instructions for Form 4562.

3. Maximize the Permanent QBI Deduction

Pass-through business owners may qualify for a deduction of up to 20% of qualified business income.

This deduction can apply to owners of:

  • Sole proprietorships
  • Partnerships
  • S corporations
  • Certain LLCs

The QBI deduction is valuable. But it is not automatic.

Your deduction may depend on:

  • Taxable income
  • W-2 wages paid by the business
  • Qualified property owned by the business
  • Whether the business is a specified service trade or business
  • Owner compensation
  • Business deductions
  • The timing of income and expenses

Large depreciation deductions can lower taxable income. They can also lower QBI. That does not mean depreciation is wrong. It means the decision requires a complete projection.

Review your books. Separate business income from investment income. Confirm reasonable S corporation compensation. Examine whether your payroll and property levels support the deduction.

The IRS qualified business income guidance provides an overview of the rules.

4. Fund the Right Retirement Plan Before the Deadline

Retirement planning is also tax planning.

Business owners should review whether a retirement plan can reduce 2026 taxable income while building long-term retirement income.

Potential strategies include:

  • 401(k) contributions
  • SEP IRA contributions
  • SIMPLE IRA contributions
  • Profit-sharing contributions
  • Cash balance plans
  • Defined benefit plan contributions

Employee elective deferrals for many 401(k) plans generally must be made through payroll by the end of the calendar year. Employer contributions may have more flexible deadlines.

Depending on the plan type, business structure, and tax filing deadline, some employer contributions may extend into 2027. SEP IRA contributions, for example, may generally be made by the business tax return deadline, including extensions. Cash balance plans require more careful advance design and funding coordination.

Do not make a retirement contribution simply because it creates a deduction.

Ask:

  • Does the contribution fit your cash flow?
  • Does it benefit eligible employees fairly?
  • Does it coordinate with owner compensation?
  • Does it support your retirement income target?
  • Does it create the right tax balance between taxable, tax-deferred, and tax-free accounts?

A retirement plan should reduce taxes today and support income for life.

5. Evaluate the Temporarily Higher SALT Deduction Cap

The federal state and local tax deduction cap is temporarily higher for eligible taxpayers in 2026. The cap may reach $40,000 for some taxpayers, subject to income-based phase-down rules and other limitations.

That creates a planning question:

Is it worth accelerating state tax payments before December 31?

The answer depends on your income, filing status, itemized deductions, state rules, cash flow, and whether you benefit from the deduction this year.

Review:

  • State estimated tax payments
  • Real estate tax payments
  • State income tax balances
  • The timing of fourth-quarter payments
  • Your expected federal itemized deductions
  • Your projected income and phase-down exposure

Business owners should also evaluate a pass-through entity tax, often called a PTET election. In certain states, an eligible partnership or S corporation may pay state income taxes at the entity level. That may create a federal business deduction and reduce the impact of the individual SALT limitation.

State deadlines vary.

Do not send a large payment without modeling the federal and state result first.

6. Track New Overtime and Tip Income Deductions

New above-the-line deductions may apply to qualifying overtime compensation and tip income for eligible workers.

These deductions may help qualifying employees reduce federal taxable income. Business owners also have an important responsibility: accurate payroll and year-end reporting.

Employers should work with their payroll provider to track qualified amounts separately. The information may need to appear correctly on Forms W-2 or applicable 1099 forms.

Review:

  • Payroll coding for qualified overtime
  • Tip reporting procedures
  • Employee classifications
  • Timekeeping records
  • Year-end payroll reports
  • Employee communications
  • Applicable income limits and phase-outs

The deductions generally belong to qualifying individuals. The business must maintain accurate records and reporting.

If your business operates in hospitality, restaurants, healthcare, transportation, or another industry with substantial overtime or tipped compensation, this review deserves immediate attention.

Do not wait for January to discover that the payroll system did not capture the necessary information.

7. Reset Your Tax Plan for 2027

A strong year-end plan does more than reduce your 2026 tax bill.

It prepares your business for the next year.

Before December 31, review:

  • 2027 quarterly estimated tax payments
  • Cash flow and tax reserves
  • Entity structure
  • Owner compensation
  • Retirement plan design
  • Business succession goals
  • Insurance and risk management
  • Investment strategy
  • Estate and wealth transfer planning
  • Tax-free and tax-deferred retirement income options

Your business structure may have worked several years ago. That does not mean it remains efficient today.

Your income may have changed. Your family may have changed. Your employees, investments, retirement goals, and estate plan may have changed.

“Your tax plan must change when your life and business change.”
