Key Dates & Tips for 2026 Tax Planning

Written by Anthony Grower | Jan 20, 2026 7:31:45 PM
Tax Refunds Are Going Digital

Starting in 2026, the IRS will stop mailing paper refund checks and move to electronic payments. This change is designed to make refunds faster and more secure. If you haven’t set up direct deposit yet, now’s a good time to do it. For more details, visit irs.gov.

With the start of a new year and tax season approaching, here are key dates and planning tips to help you stay organized and make the most of your financial opportunities.

  • Your 2025 tax return is due on Wednesday, April 15, unless you file an extension.

  • If you took a retirement account distribution in 2025, expect to receive a Form 1099-R by late January.

  • By late February, you’ll receive a Form 1099 document for taxable accounts. This form shows earned dividends and interest income and comes from your account custodian.

  • You have until April 15 to contribute to your IRA (deductible and non-deductible), Roth IRA, and HSA for the 2025 tax year.

  • Filers over 50 years old are eligible for catch-up contributions for 401(k), 403(b), 457(b), traditional and Roth IRAs, as well as SIMPLE IRAs.  

  • Making quarterly estimated tax payments? Mark your 2026 calendar with the following due dates: April 15, June 15, September 15, and January 15, 2027.

  • For 2026, the standard deduction has increased to $16,100 for single filers; $32,200 for married filing jointly; and $24,150 for head of household filers.

  • If your employer updated compensation for the new year, check your elective deferrals to make sure you’re maximizing savings opportunities.

  • The One Big Beautiful Bill Act (OBBBA), signed into law in 2025, brings several tax changes for 2026 and beyond, and some that may impact your 2025 return.
