Editorial boundary
These pages explain official dates, source status, and preparation context. They do not decide whether you must file, how much to pay, whether you qualify for credits, or how to handle a personal tax situation.
Topic boundary
Federal tax dates without personal tax advice
The tax topic hub groups IRS-source-reviewed pages for federal filing dates, estimated tax payment dates, and preparation checklists. It is meant to help readers find the right official source path, not to decide personal tax questions.
That boundary is especially important because tax content can affect financial decisions. Punilog can explain what an IRS source says about a date, where an extension source fits, and which questions need IRS instructions or professional help. It should not tell a reader whether they must file, what they owe, which deduction or credit to claim, or whether a penalty applies.
Use this hub for three tasks
Find a date
Use the calendar page for a quick view of filing, extension, and estimated tax dates that were checked against IRS sources.
Understand a deadline
Use the guide pages when you need to know what the date does and does not answer, including extension and payment boundaries.
Prepare records
Use the checklist page to organize account access, records, forms, identity checks, and source links before filing.
What still needs a separate check
- State taxes. State filing and payment dates need state agency sources.
- Fiscal-year or special rules. IRS publications and instructions control where the ordinary calendar-year date does not fit.
- Disaster relief. IRS relief notices can change timing for affected taxpayers without changing the ordinary national date.
- Personal tax choices. Filing status, credits, deductions, payment amounts, penalties, and strategy are outside this site’s scope.

How to use this topic hub
Start with the calendar page if you only need the next verified date, then use the guide pages when you need the source context behind a specific deadline. The topic hub intentionally keeps federal dates separate from state tax dates, personal filing requirements, credits, deductions, penalties, and payment-plan decisions, because those questions can depend on facts outside this site’s scope.
What gets reviewed before updates
Updates to this topic should be checked against the IRS source named on the affected page, then logged with the verification date and the reason for the change. That keeps older deadline pages from drifting into unsupported tax guidance.
