I spent years preparing tax returns for foreign-owned single-member LLCs. Every tax season, I found myself doing the same tedious work: manually filling out Pro Forma 1120s, copying data into Form 5472 (Parts I, II, III), and editing PDFs for hours.

The frustrating part? Most tax software treats foreign-owned SMLLC returns as an afterthought. They charge the same prices as full corporate returns but offer no automation for this specific workflow. You end up paying premium prices for software that doesn't actually help with the repetitive parts.

So I built FastFile to solve this problem. It's focused entirely on foreign-owned SMLLC filings. Upload prior-year returns, and the forms are pre-filled automatically. No more PDF editing. No more copying the same data into multiple fields.

Differentiation

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.
