Quick answer: A good personal tax year has four rhythms: gather documents and file in the winter and early spring, check withholding and estimated payments in the spring and summer, plan in the fall, and finish year-end moves like charitable gifts, required distributions, and retirement contributions by December 31. Keep a single folder for tax records all year, mark the April, June, September, and January estimated tax dates, and remember that some moves, like IRA contributions, can still be made up to the filing deadline.

Most of the stress we see at tax time comes from things that were easy to handle months earlier: a missing document, a forgotten estimated payment, a gift that was meant to happen in December. A little attention spread across the year makes April a much calmer month.

January through April: gather, organize, and file

January

  • Pay the fourth-quarter estimated tax payment, due around January 15, if you make them.
  • Watch for W-2s, which employers must send by January 31, and 1099s for interest, dividends, retirement distributions, and freelance work. Brokerage statements often arrive later, sometimes into March, and corrected forms are common.
  • Gather property tax bills, mortgage interest statements (Form 1098), childcare receipts, college tuition statements (Form 1098-T), and charitable receipts.

February and March

  • Check your documents against last year's return. If last year you had a 1099 from a bank or brokerage and this year you do not, find out why before filing.
  • Retrieve your IRS Identity Protection PIN if you have one; a new one is issued each year.
  • If you have health coverage through the marketplace, wait for Form 1095-A.

By mid-April

  • File your federal and New York returns, or file extensions (Form 4868 federally and Form IT-370 for New York). An extension gives more time to file, not more time to pay.
  • Make prior-year IRA and HSA contributions, which can be made up to the filing deadline.
  • Make your first-quarter estimated payment for the new year.

May through August: check the course

Spring and summer are the right time to make sure the current year is on track.

  • Review your withholding. If you owed a lot or got a large refund, adjust your W-4 and New York IT-2104. The IRS Tax Withholding Estimator is useful for the federal side.
  • Make the June estimated payment, due around June 15.
  • Life changes: marriage, divorce, a new baby, a new job, or the loss of a spouse all change your tax picture. Update withholding and beneficiaries when they happen.
  • Keep records as you go. Save receipts for deductible expenses, mileage logs if you are self-employed, and records of home improvements, which affect your basis when you sell.
  • Check your property tax relief. If you bought a home, register for the New York STAR credit.

September through November: plan while you still can

Fall is when planning actually pays off, because there is still time to act.

  • Make the September estimated payment, due around September 15.
  • Project your income for the year. Was there a bonus, a large capital gain, a home sale, or a drop in income? Projections drive almost every other decision.
  • Review investment gains and losses. Selling losing positions to offset gains can reduce tax, within the wash sale rules.
  • Decide whether to itemize or take the standard deduction, which affects whether bunching charitable gifts or property tax payments makes sense. See our article on itemizing versus the standard deduction.
  • Open enrollment. Choose health insurance, flexible spending, and dependent care accounts with taxes in mind.
  • Consider a Roth conversion in a lower-income year.

December: finish the year-end moves

Several items must be completed by December 31 to count for the year:

  1. Required minimum distributions from IRAs and retirement plans, if you are of RMD age. The penalty for missing one is steep.
  2. Charitable gifts, including qualified charitable distributions from an IRA if you are eligible.
  3. 401(k) and 403(b) contributions through payroll, which generally must come out of a paycheck dated in the year.
  4. Use-it-or-lose-it flexible spending account balances, depending on your plan's rules.
  5. 529 plan contributions if you want a New York deduction for the year.
  6. Gifts to family members within the annual gift tax exclusion, which the IRS adjusts each year.

All year: simple record-keeping habits

A shoebox works, but a dedicated folder, paper or digital, works better. Keep:

  • Tax returns permanently, and supporting records for at least three years after filing, longer for anything involving property or investments.
  • Closing statements and improvement receipts for every home you own.
  • Records of nondeductible IRA contributions (Form 8606) so you do not pay tax twice.
  • Notices from the IRS or New York, with your responses.

If you would rather hand off the deadlines and paperwork, our personal tax preparation clients across Central New York get reminders and a planning check-in each fall.

Frequently asked questions

When should I start getting my tax documents together?

Start in January as forms arrive, and keep them in one place. Most W-2s arrive by early February, but brokerage 1099s and K-1s can arrive much later. Wait until you have everything before filing to avoid amending.

What are the estimated tax due dates for individuals?

For both federal and New York estimated tax, the four payments are generally due around April 15, June 15, September 15, and January 15 of the following year. Dates shift to the next business day when they fall on a weekend or holiday.

What has to be done by December 31 to count for the tax year?

Required minimum distributions, charitable gifts, payroll retirement contributions, and many investment sales must be completed by December 31. IRA and HSA contributions are the main exception; they can generally be made up to the April filing deadline for the prior year.

How long should I keep tax records?

Keep returns indefinitely and supporting documents for at least three years after the return was filed. Keep records related to property and investments for as long as you own the asset plus three years after you report its sale.
