Value Proposition
Why FastFile Is Different
Niche-focused, not generic
Big tax software tries to do everything for everyone. FastFile does one thing well: automate foreign-owned SMLLC filings. Every feature exists because it saves time on this specific workflow.
Better pricing for this workflow
You shouldn't pay corporate software prices for a return that takes 15 minutes once it's automated. FastFile is priced specifically for foreign-owned SMLLC filings.
Built from real experience
FastFile was built by someone who actually prepares these returns. Every feature comes from real pain points, not guesswork about what tax preparers might need.
