Penalty category
Distinguishes timing-related IRS penalties from issues that need a different relief conversation.
Individual penalty check
If you paid an IRS penalty or interest personally, it may still be worth preserving before the deadline.
Individuals are in scope too. The main questions are what the IRS charged, which return was involved, and whether the underlying due date falls inside the COVID postponement period people are reviewing under Kwong.
Common form
Form 1040
Common issues
Late filing, late payment, estimated tax penalties, and related interest
Main question
What original deadline was the charge tied to?
Best path
Self-check first, then decide DIY, CPA, or specialist review
What this check looks for
Return and year
Helps anchor whether the issue came from an individual return path or something more mixed.
Due-date window
Tests the original timing against the relevant COVID postponement period instead of relying on headlines alone.
Records available
Shows whether you can move now or first need to pull a notice, transcript, or payment history.
Individual self-check
Start with the facts the IRS actually used, not the assumptions people make from social posts.
This version is framed for individual filers, but the shared assessment still catches overlap with business entities, payroll issues, and mixed notices.
This is educational self-assessment only and does not replace tax or legal advice.
Recommended next steps
Your answers look mixed across personal and business paths. Start by gathering records for the issue you care about most first, then use the notes to organize the rest.
Get the individual checklist and update alerts
We can email your result notes, a records checklist, and meaningful appeal-status updates so you can act with a cleaner paper trail.
DIY and CPA path
Pull your IRS notice or transcript, confirm the form and original due date, then decide whether to preserve the issue yourself or hand it to your CPA.
Want help after you self-check?
If you prefer a guided review path after you see your result, the WonderTrust option is available as a secondary step.
Review WonderTrustHow it works
1
Identify the charge
Separate late-filing, late-payment, estimated tax, and related interest issues from everything else.
2
Match the timing
If the original due date lands inside the key window, the issue may be worth preserving before the deadline.
3
Save your next-step notes
Keep the checklist for yourself, send it to a CPA, or look at optional outside help after you self-check.
Important context
You do not need to know everything up front
If you are unsure about the exact penalty basis, the assessment can still move you into a sensible next step.
Not every individual issue is a fit
Some personal tax problems will fall outside the window or involve penalty types that are not good Kwong-style candidates.
This is not a jackpot page
The goal is disciplined self-orientation before the deadline, not hype about guaranteed refund money.
Frequently asked questions
Does this apply only to business owners?
No. Individuals are in scope too, but the exact fit depends on the return path, penalty type, and original due date.
What if I only had interest?
Interest can still matter, especially if it was attached to a timing-related penalty, but that usually pushes you toward records gathering first.
Can I still use this if I had business and personal notices?
Yes. The universal assessment is designed to catch mixed fact patterns instead of assuming everything was purely personal.
