Frequently Asked Questions
Are these the real government forms?
Yes. Every 'Download Official PDF' button links straight to the .gov authoritative source — irs.gov for IRS forms, uscis.gov for USCIS, ssa.gov for Social Security, and state.gov for State Department forms. We never self-host or modify government forms.
Is Mubboo affiliated with the IRS, USCIS, or any government agency?
No. Mubboo is an independent publisher. Our guides explain how to fill out federal forms in plain English, but we are not the IRS, USCIS, SSA, DOS, or any other federal agency. Always confirm with the official agency before filing.
Do you store any of my information when I download a form?
No. We link directly to the official agency PDF — you download it from the government website, not from us. We don't see or store any information you put on the form.
When will the 'Fill Online' feature launch?
We're building a guided online form filler that lets you complete each form right in your browser, then download a print-ready PDF. It's coming in the next release — until then, the downloadable PDF and our line-by-line guide are the fastest path to a correctly filled form.
Can you help me file a form?
Our guides explain what each field means and how to avoid common mistakes, but we can't file on your behalf or give individualized tax, legal, or immigration advice. For complex situations, work with a licensed tax professional or an immigration attorney.
Why is form X missing?
We've launched with the 10 highest-volume federal forms and are adding more. If a form you need is missing, the official agency site (irs.gov, uscis.gov, ssa.gov) always has it. Email us if you'd like us to prioritize a specific form.
