April 15 Tax Filing Deadlines: A Guide for Greater Boston Taxpayers

The final stretch of tax season is here. For residents and business owners in Quincy, Braintree, and the greater Boston area, April 15, 2026, is the pivotal date to file your 2025 federal tax return and pay any taxes owed, or to file for an automatic extension. As a local accountant and IRS Enrolled Agent, I want to ensure you do not miss any crucial requirements that could impact your financial standing.

Beyond the Basic Return: What Else is Due?

The April 15 deadline extends far beyond standard individual filings. Here is what else requires your immediate attention:

  • Tax Year 2025 Balance-Due Payments: An extension to file is never an extension to pay. If you expect a balance due—particularly common for small business owners and those managing real estate investor taxes—you must estimate and submit that payment with your extension request. Late payment penalties accrue immediately on unpaid balances.

  • 2025 IRA Contributions: April 15 is your absolute final opportunity to fund a Roth or traditional IRA for the 2025 tax year, even if your tax preparer files an extension on your behalf.

  • 2022 Tax Refund Claims: The regular three-year statute of limitations to claim a refund for your 2022 tax return closes on April 15, 2026. Miss this window, and those funds are permanently forfeited.

  • Foreign Bank and Financial Accounts (FBAR): Taxpayers with $10,000 or more in foreign accounts at any time during 2025 must file their FBAR. While an automatic extension to October 15 applies if you miss April 15, proactive filing helps prevent severe penalties during any future IRS auditing procedures.

  • Q1 2026 Estimated Tax Payments: Self-employed professionals and business owners need to remit their first 2026 quarterly estimated tax payment by April 15. Your accountant relies on accurate bookkeeping and payroll records from 2025 to calculate this liability correctly.

Managing Missing Documents and Balances Due

Our office is navigating back-to-back appointments, and finalizing returns requires complete data. If missing information is delaying your tax preparation, please forward those documents immediately. Whether it is a missing 1099 or finalizing your monthly sales and meals tax filing records, waiting until the final hour risks an incomplete return.

If you know you cannot gather the details in time, contact us so our EA team can secure an extension and prepare your estimated tax vouchers. What if your return is finished, but you cannot cover the tax liability? Do not ignore the filing deadline. File on time and contact us to discuss installment agreements or other resolution options.
