The 2026 Tax Reset: What NYC Business Owners Should Review Before Year-End

A practical guide to the major tax planning areas business owners should revisit after recent federal tax changes, including deductions, entity structure, payroll, and investment timing. The IRS notes that the One Big Beautiful Bill Act significantly affects federal taxes, credits, and deductions.

Year-end tax planning in 2026 is not simply a matter of accelerating expenses in December. The One Big Beautiful Bill Act made several major business provisions permanent or more generous. New York State and New York City do not always follow federal treatment, however, so a deduction that looks attractive federally may produce a different local result.

The practical goal is to connect tax planning with cash flow, hiring, capital spending, owner compensation, and financial reporting while there is still time to act.

Start With the Deductions That Can Change Investment Timing

Permanent 100% bonus depreciation is especially important for equipment-heavy businesses. Eligible property acquired after January 19, 2025, and placed in service may qualify for a full first-year federal deduction. This can benefit companies purchasing machinery, computers, furniture, software, or qualified improvements.

Section 179 also deserves a fresh look. For tax years beginning in 2026, the federal deduction limit is $2,560,000, with the phaseout beginning when qualifying property placed in service exceeds $4,090,000. Unlike bonus depreciation, Section 179 is generally limited by taxable business income, so the two provisions should be modeled together rather than treated as interchangeable.

Ordering equipment is not enough; property generally must be ready and available for business use before year-end. Financing, expected profitability, state adjustments, and financial-statement effects should be considered before claiming the largest possible current deduction.

Revisit Research Costs, Financing, and the Qualified Business Income Deduction

Businesses that develop software, improve production methods, design products, or conduct technical testing should review the restored deduction for qualifying domestic research expenditures. For tax years beginning after 2024, these costs may generally be deducted currently, and special rules may allow recovery of some previously capitalized costs. Identify qualifying expenses before closing the books.

Highly leveraged companies should revisit the business-interest limitation. The federal calculation again uses an EBITDA-style measure for tax years beginning after 2024, potentially increasing deductible interest and changing borrowing or acquisition models.

Owners of eligible pass-through businesses should not assume that the permanent Section 199A qualified business income deduction will calculate itself. The deduction can be as much as 20% of qualified business income, but taxable income, wages, qualified property, business type, and owner-level items can change the result. A year-end projection may show that compensation, retirement plan contributions, capital purchases, or the timing of income should be adjusted.

Test the Entity Structure Against New York City Reality

A federal S corporation election may reduce employment taxes in the right circumstances, but New York City does not recognize federal or New York State S corporation status for its General Corporation Tax. That city-level treatment can materially change the comparison among an S corporation, C corporation, partnership, or disregarded LLC.

An entity review should include reasonable owner compensation, the qualified business income deduction, NYC General Corporation Tax or Unincorporated Business Tax exposure, benefits, administrative costs, succession plans, and whether profits will be distributed or reinvested. Changing entities for one federal benefit can create legal, payroll, and city-tax costs that outweigh the savings.

New York conformity is another important check. New York State generally requires adjustments for federal bonus depreciation under Internal Revenue Code Section 168(k), subject to limited exceptions. As a result, federal and New York depreciation schedules may diverge for years. Maintain separate fixed-asset records so future additions, disposals, and state modifications can be reported accurately.

Close the Year With a Tax Forecast, Not a Guess

Before year-end, update the financial statements, reconcile payroll and sales tax accounts, review receivables and inventory, and prepare federal, state, and city tax projections. Compare the forecast with estimated payments and first-quarter cash needs. Payroll deserves particular attention. For 2026, the Social Security tax rate remains 6.2% for both employer and employee on wages up to $184,500, while Medicare remains 1.45% for each side with no wage cap. Contractor files should also be reviewed because the federal reporting threshold for certain business payments rises to $2,000 for payments made in 2026. Even when no form is required, businesses still need complete books, valid expense support, and correct worker classification.

A sound year-end plan is a sequence of decisions: finalize reliable books, project taxable income, test major purchases, revisit owner compensation, verify state and city differences, and schedule actions that must occur before December 31. Eligibility should be evaluated with professional tax and legal advisers.
