Tax season is here and for millions of individuals and business owners across New York and Long Island, March means one thing: the clock is ticking. With the April 15th federal tax deadline approaching fast, March is the critical window to get organized, minimize what you owe, and avoid costly last-minute mistakes.
At Nazaire & Co., we’ve been guiding individuals, families, and businesses through tax season since 1997. We know that tax time doesn’t have to be a source of dread. With the right strategies and the right team in your corner you can turn deadline season into an opportunity to protect your wealth and set yourself up for a stronger financial year ahead.
Here is your complete March Tax Deadline Survival Guide, packed with actionable strategies, insider tips, and expert guidance from our Long Island and New York City CPA team.
1. Know Your Key March and April Deadlines
Before you can survive tax season, you need to know exactly what you’re up against. Here are the most important dates to keep on your radar:
March 17, 2026: Corporate tax returns (Form 1120-S for S-Corporations and Form 1065 for Partnerships) are due. If you haven’t filed, this is an urgent priority.
April 15, 2026: Individual federal income tax returns (Form 1040) are due, along with any taxes owed. This is also the deadline to contribute to a Traditional IRA or Roth IRA for the 2024 tax year.
April 15, 2026: First quarter 2025 estimated tax payments are due for self-employed individuals and business owners.
October 15, 2026: Extended individual returns are due — but filing an extension only extends the time to file, not the time to pay. Any taxes owed are still due by April 15.
Pro Tip from Nazaire & Co.: Filing an extension is not a penalty-free delay on payments. If you owe taxes and miss the April 15 payment deadline, the IRS will assess interest and failure-to-pay penalties — regardless of whether you filed for an extension. If you are unsure of your liability, our team can help you calculate a safe estimate to pay by the deadline.
2. Gather These Documents Before You Meet with Your Accountant
One of the biggest sources of tax season stress is scrambling to find paperwork at the last minute. Getting organized in March even a few days before your appointment, can save significant time, reduce errors, and ensure you don’t miss valuable deductions.
Here is a core checklist of documents to gather:
Income Documents: W-2s from all employers, 1099s for freelance or contract work, 1099-INT and 1099-DIV for interest and dividend income, Schedule K-1s for partnership or S-Corp income, Social Security benefit statements, and rental income records.
Deduction Records: Mortgage interest statements (Form 1098), property tax bills, charitable contribution receipts, medical expense records, student loan interest statements (Form 1098-E), and education expenses (Form 1098-T).
Business Owners: Profit and loss statements, payroll records, business expense receipts, vehicle mileage logs, home office measurements, utility bills, and retirement plan contribution records.
Prior Year Returns: Your 2023 federal and state tax returns are useful for reference and for accurate carry-forward figures.
The more organized you are before meeting with a CPA, the more time your advisor can spend finding savings — rather than chasing paperwork.
3. Smart Strategies to Maximize Your Tax Savings
Tax minimization isn’t just about what you did last year; it’s about identifying every legitimate opportunity to reduce what you owe right now. Here are the strategies our CPAs at Nazaire & Co. use to help clients keep more of their money:
Maximize Retirement Contributions: You can still contribute to a Traditional IRA or SEP-IRA for the 2024 tax year — right up until April 15, 2025. For 2024, the IRA contribution limit is $7,000 ($8,000 if you’re age 50 or older). SEP-IRA contributions for self-employed individuals can be significantly higher. Contributions to a Traditional IRA may be tax-deductible, reducing your adjusted gross income (AGI) and potentially your overall tax bill.
Claim Every Business Deduction You’re Entitled To: Business owners often leave money on the table by underreporting legitimate deductions. This includes home office expenses, vehicle business use, professional development, software subscriptions, and equipment purchases under Section 179 expensing. Our business tax specialists at Nazaire & Co. work with clients in industries ranging from construction to healthcare to real estate to ensure every deduction is captured.
Review Your Filing Status: Your filing status, single, married filing jointly, married filing separately, or head of household significantly impacts your tax rate and the deductions and credits available to you. Life changes like marriage, divorce, or a new dependent in 2024 may mean a different status applies to you this year.
Take Advantage of Above-the-Line Deductions: These deductions reduce your AGI whether or not you itemize. They include student loan interest, educator expenses, self-employment taxes, health insurance premiums, and contributions to HSAs and retirement accounts. Lowering your AGI can also make you eligible for other credits and deductions that phase out at higher income levels.
Don’t Forget State and Local Taxes: New York State and New York City both impose their own income taxes — some of the highest in the nation. Our team at Nazaire & Co. specializes in New York State and local tax planning, helping clients minimize their full state tax liability, not just their federal bill. We also assist with property tax strategies for Long Island homeowners.
Consider Tax Loss Harvesting: If you have investment accounts, 2024 may have produced both gains and losses. Realized capital losses can offset capital gains, and up to $3,000 in excess losses can offset ordinary income per year. Our integrated tax and financial planning team can review your investment activity to ensure you are maximizing this opportunity.
4. Business Owners: Critical March Action Items
Business owners face a more complex tax landscape than individual filers, and March is a critical month for those running S-Corporations, partnerships, LLCs, and sole proprietorships. Here’s what you need to address right now:
S-Corp and Partnership Returns Are Due March 17: If you haven’t filed, act immediately. Late filing can result in significant per-partner, per-month penalties even if no tax is owed.
Review Your Entity Structure: Is your current business structure (sole proprietor, LLC, S-Corp, C-Corp) still the most tax-efficient option for your business size and income? March is a good time to have this conversation with your CPA, so changes can be implemented before the new tax year gets fully underway.
Plan Your Q1 Estimated Tax Payment: Self-employed individuals and business owners must pay estimated taxes quarterly. The first Q1 2025 estimated payment is due April 15. Underpaying can result in underpayment penalties. Our team can calculate your optimal payment amount.
Evaluate Cost Segregation Opportunities: For real estate investors and property owners, cost segregation studies can dramatically accelerate depreciation deductions, generating significant tax savings. Nazaire & Co. offers specialized cost segregation services for Long Island and NYC property owners.
5. How to Reduce Tax Season Stress Right Now
Beyond the financial strategies, tax season stress is real and it often comes from procrastination and uncertainty. Here are practical ways to reduce stress between now and April 15:
Schedule Your Appointment Early: The closer you get to April 15, the harder it is to get time with a qualified CPA. If you haven’t scheduled your tax appointment with Nazaire & Co., do it today. Early filers typically have more time for planning conversations — not just compliance.
Use a Secure Client Portal: At Nazaire & Co., we make document submission easy with secure digital tools. No more printing and faxing you can upload your documents safely from home or the office.
Ask About Extensions Before It’s Too Late: If you genuinely cannot gather all your documents in time, filing an extension is better than filing an inaccurate return. But remember, you must still estimate and pay any taxes owed by April 15 to avoid penalties.
Don’t DIY If Your Situation Is Complex: Tax software works fine for very simple returns. But if you own a business, have multiple income sources, went through a major life event, own real estate, or have investments, a professional CPA will almost certainly save you more than the cost of their fee and keep you out of trouble.
