How It Works
The Corporate Transparency Act (CTA) requires most US business entities to file Beneficial Ownership Information (BOI) reports with FinCEN. This calculator estimates your filing cost, deadline, and complexity based on your entity details.
The basic rule:
- BOI reports are filed directly with FinCEN at no government fee — costs come from professional preparation
- Entities formed before 2024 had until January 1, 2025 (deadline subject to legal challenges and extensions)
- Entities formed in 2024 must file within 90 days of formation; 2025+ entities within 30 days
- Penalties for willful non-compliance: up to $500/day (max $10,000) and potential criminal penalties up to 2 years imprisonment
The CTA has faced legal challenges, and enforcement timelines have shifted. Check FinCEN's website for the most current deadlines and requirements. For simple entities with 1-2 individual owners, DIY filing is straightforward. For complex ownership structures, professional help is worth the cost to avoid errors.
Tips & Considerations
- Double-check your entity type before calculating — even small input errors can significantly change your results.
- Run the calculator with different values to compare scenarios and find the optimal approach for your situation.
- Pay attention to both estimated filing cost and filing deadline — they work together to give you the full picture.
- Bookmark this page for quick access next time you need to get accurate results.
- If you're unsure about your number of entities to file, start with a conservative estimate and adjust from there.
Frequently Asked Questions
Who has to file a BOI report?
Most LLCs, corporations, and similar entities registered with a state must file. There are 23 exemptions, mainly for large companies (500+ employees and $5M+ revenue), regulated entities (banks, insurance companies, SEC-registered firms), and inactive entities. Single-member LLCs, small businesses, and most partnerships must file. Sole proprietorships without an LLC do not need to file.
What information is required in the BOI report?
For each beneficial owner (anyone with 25%+ ownership or substantial control): full legal name, date of birth, residential address, and an ID document number (driver's license or passport) with an image of the document. For the company: legal name, trade names, address, state of formation, and EIN/TIN.
Can I file the BOI report myself?
Yes. FinCEN's online filing system (boiefiling.fincen.gov) is free and relatively straightforward for simple entities. For a single-member LLC with one owner, filing takes about 15-30 minutes. Complex structures with trusts, foreign owners, or nested entities benefit from professional guidance to ensure accuracy.
What are the penalties for not filing?
Willful failure to file can result in civil penalties of up to $500 per day (capped at $10,000) and criminal penalties including up to 2 years imprisonment and $10,000 fine. However, enforcement has been gradual and the CTA has faced court challenges. Filing late is much better than not filing at all — FinCEN has indicated a focus on willful non-compliance rather than inadvertent delays.
Is the CTA Filing Calculator free to use?
Yes, completely free with no signup required. Use it as many times as you need — there are no limits or hidden fees.
