Updated · Planning for tax year 2026 and the year ahead.
Running a business in New York means managing more than sales, expenses, and payroll. Federal taxes, New York State requirements, and applicable New York City taxes can all affect how much of your profit remains available to grow the business.
Tax planning connects those obligations with decisions you make throughout the year. Your business structure, owner compensation, retirement contributions, and investment timing can influence your tax bill and cash flow. The right approach depends on your actual numbers and goals.
For businesses preparing to file 2026 returns in 2027, reviewing these areas before year-end can reveal opportunities while there is still time to act.
Why Tax Planning Matters Before Filing Season
Tax preparation reports what happened. Tax planning helps you evaluate what to do next. A useful plan begins with current bookkeeping, a realistic profit forecast, and an estimate of both business and owner tax obligations.
Some decisions need attention before December 31. Others, including certain retirement contributions and elections, may have later deadlines. Reviewing the rules early helps you preserve options and budget for payments rather than discovering a shortfall when the return is ready.
Common Tax Planning Mistakes
- Using last year’s profit as this year’s forecast. Growth, a major contract, or a change in expenses can make old payment estimates unreliable.
- Assuming an LLC or S corporation automatically saves tax. The result depends on tax classification, compensation, state and city treatment, and the cost of maintaining the structure.
- Mixing business and personal spending. Separate accounts and clear records make it easier to identify eligible expenses and support the amounts reported.
- Buying something only to get a deduction. A deduction reduces taxable income; it does not reimburse the purchase price.
- Waiting until filing season to discuss elections. Some opportunities have deadlines during the tax year they apply to.
Tax Planning Strategies Worth Reviewing
1. Evaluate Your Entity and Owner Compensation
An LLC is a legal structure, and its income-tax treatment can vary. Comparing sole proprietor, partnership, S corporation, and C corporation treatment requires looking at the business and its owners together.
S corporation treatment may offer employment-tax advantages in suitable circumstances, but an owner who works in the business must receive reasonable compensation for those services before taking non-wage distributions. Payroll, administrative costs, and other taxes belong in the comparison. IRS S corporation compensation guidance.
New York State generally requires a separate S election using Form CT-6, with shareholder consent, unless mandatory-election rules apply. New York City does not recognize S corporation treatment and generally subjects federal S corporations doing business in the city to its General Corporation Tax. New York S corporation rules and NYC General Corporation Tax guidance.
2. Review Pass-Through Entity Tax Elections
Eligible partnerships and New York S corporations can consider New York’s optional pass-through entity tax, or PTET. Qualifying entity-level state income-tax payments can produce a federal deduction, while eligible owners may claim corresponding New York credits. The overall benefit depends on ownership, residency, income, and other deductions. New York PTET guidance and IRS guidance on entity-level state tax deductions.
The election is annual and generally must be made by March 15 of the tax year. The ordinary 2026 election deadline has already passed. For eligible entities considering 2027 PTET, the election deadline is generally March 15, 2027; that election applies to 2027, rather than the 2026 return being prepared at the same time. NYC PTET has separate eligibility requirements.
3. Coordinate Retirement Contributions With Cash Flow
A suitable retirement plan can support long-term savings and may provide a current deduction for eligible contributions. Options include SEP plans and, for qualifying businesses without employees other than an owner’s spouse, one-participant 401(k) plans.
Compare contribution limits, employee coverage, administrative duties, and available cash before choosing a plan. Establishment, deferral-election, and funding deadlines vary; certain employer contributions can be made after year-end. Roth contributions generally do not provide a current income-tax deduction. IRS SEP guidance and IRS one-participant 401(k) guidance.
4. Plan Equipment Purchases and Expense Timing
Eligible assets may qualify for Section 179 expensing or bonus depreciation. Current federal rules generally allow 100% bonus depreciation for qualifying property acquired and placed in service after January 19, 2025, subject to acquisition rules and other requirements. Simply ordering equipment before year-end does not establish that it is ready and available for business use. IRS depreciation guidance.
Federal, New York State, and NYC depreciation treatment can differ. Project each applicable tax separately before relying on a federal deduction to reduce the entire bill. New York guidance on certain depreciation and research deductions.
Income and expense timing also depends on your accounting method and other rules. Delaying an invoice does not necessarily defer taxable income, and prepaying an expense does not always create an immediate deduction. Start with a business need, then evaluate the tax treatment.
5. Review the Qualified Business Income Deduction
Eligible owners of sole proprietorships and pass-through businesses may qualify for the federal qualified business income deduction, or QBI deduction, generally up to 20% of qualified business income, subject to limitations. The deduction remains available under current law for 2026 and later years.
Taxable income, business type and, in some cases, wages and qualified property affect the result. Retirement contributions and other deductions can also change QBI, so evaluate their combined effect rather than treating each deduction as a separate saving. IRS QBI deduction guidance.
6. Update Estimated Payments and Local Tax Projections
Required estimated payments depend on the taxpayer and available withholding. Payment timing matters as well as the total paid. A business owner can face an underpayment penalty even when the final return shows a refund. Safe-harbor and annualized-income rules may help determine the appropriate payment approach. IRS estimated tax guidance.
NYC sole proprietors, partnerships and certain LLCs should also review the Unincorporated Business Tax. It generally applies at 4% of taxable income allocated to NYC, subject to exemptions, deductions and credits. Other obligations, including MCTMT where applicable, should be included in the forecast. NYC UBT guidance.
What a Tax Deduction Actually Saves
Illustrative example: Assume a business has a fully deductible $10,000 expense and the applicable combined marginal income-tax rate is 30%. Ignoring other tax interactions, the deduction would reduce income tax by approximately $3,000. The business still spends $10,000, leaving an approximate after-tax cost of $7,000.
This is a simplified illustration, not a client result or a savings guarantee. Actual outcomes depend on deduction limits, federal and state differences, QBI, and other factors.
A worthwhile purchase can support operations and provide a tax benefit. An unnecessary purchase still uses cash. Good planning compares the after-tax cost with the value the decision brings to your business.
A Practical Year-End Planning Checklist
- Bring bookkeeping up to date. Reconcile accounts, review receivables, and identify missing records.
- Forecast full-year profit. Include expected revenue, expenses, payroll, and major transactions.
- Review owner compensation and elections. Confirm current treatment and evaluate changes for the coming year.
- Evaluate planned purchases and retirement contributions. Check eligibility, deadlines, and the effect on available cash.
- Review state and city exposure. Consider new employees, locations, inventory, and business activity.
- Confirm payment requirements. Review business and owner estimates, withholding and applicable local taxes.
- Set a date for the next review. Revisit the plan when profit, ownership, or operations change.
How a CPA Firm Helps
A CPA can help turn financial records into a practical plan that reflects both the business and its owners. That work can include:
- Tax projections to estimate upcoming obligations and prepare for payments.
- Entity and election reviews to compare federal, state and city treatment.
- Deduction and credit reviews to identify applicable opportunities and supporting records.
- Cash-flow planning to weigh tax benefits against spending, payroll and retirement funding.
- Notice and examination support when a tax authority requests information or questions a return.
