Frequently asked questions
Quick answers about how Tax Due Dates works and how to use this 2026 Tax Deadline Guide.
Is this guide a substitute for a CPA or enrolled agent?
No. Tax Due Dates is an educational and organizational tool. We help you see what is due and when, with friendly explanations, but we do not provide individualized tax advice. You should still work with a qualified tax professional to prepare and file your returns.
Which businesses is the 2026 Tax Deadline Guide designed for?
The guide is tailored for U.S. small businesses that operate on a calendar year—sole proprietors, single‑member LLCs, partnerships, S corporations, C corporations, and small employers with W‑2 staff or 1099 contractors. If you operate on a fiscal year or have complex international issues, some dates will differ.
Do your reminders include state and local tax deadlines?
Right now, our core 2026 reminders focus on federal IRS deadlines. We provide guidance on common state filings inside the dashboard, but specific state and local due dates vary widely. Always confirm with your state or local revenue agency or your tax professional.
What happens if a due date falls on a weekend or federal holiday?
In most cases, when a tax deadline falls on a Saturday, Sunday, or legal holiday, the due date moves to the next business day. Our calendar and reminder system automatically reflect those adjustments, but you should always confirm for your specific filing and location.
Can I cancel the reminder service after tax season?
Yes. You can upgrade, downgrade, or cancel your plan at any time from your account dashboard. There are no long‑term contracts; you simply keep the service for as long as it’s helpful for your business.
