FAQ

About tax filing.

Is the CPA licensed in my state?
Yes. We match you with a CPA licensed in your formation state (and any state where you have tax obligations). All CPAs in our partner network are vetted; we verify state license status annually.
What if I already have a CPA?
You can keep them. Many of our customers do. The File.Business value is the compliance integration (deadline tracking, Document Locker, score updates), not necessarily the CPA service. We coordinate with external CPAs on request.
How does S-Corp election work?
If you operate as an LLC but pay self-employment tax on >$80K in profit, S-Corp election typically saves several thousand dollars per year. We surface the analysis during your first tax filing and file Form 2553 if it makes sense.
Do you handle audits?
Audit response is available as a separate engagement. Most audits never happen; for the small percentage that do, we coordinate with the partner CPA on response, document preparation, and IRS communication.
When is the deadline?
Federal corporate returns: April 15 (or extension to October 15). S-Corp / partnership: March 15. We track every deadline including state-specific extensions and surface them on your dashboard.
Can I file an extension?
Yes. We file Form 7004 (federal) and state-specific extensions automatically if your filing is going to be late. Extension does not extend the payment deadline; we calculate estimated taxes due.
