DIY vs Formation Agent: The True Cost of Forming a Wyoming LLC (2026)

# DIY vs Formation Agent: The True Cost of Forming a Wyoming LLC (2026) You can form a Wyoming LLC yourself for the $100 state filing fee. So why does anyone pay a formation agent? Because the LLC itself is 20% of the job. The other 80% is EIN, Operating Agreement, US bank account, compliance calendar and the four decisions where DIY founders lose an average of $1,800 in year one. Here's the honest cost breakdown — no hidden fees, no upselling, real 2026 numbers. ## DIY: what it actually costs - **Wyoming Secretary of State filing:** $100. - **Wyoming Registered Agent (mandatory):** $39–$149/year. - **EIN filing:** $0 direct with IRS if you have a US SSN or ITIN. If you don't (most non-residents), Form SS-4 is mailed or faxed to the IRS International Unit with 4–8 week processing. Miss any field and it comes back for correction — add 4 weeks. - **Operating Agreement:** $0 to draft yourself, $200–$500 for a template from a legal marketplace, $800–$2,000 for a US lawyer. Mercury will not open an account without a compliant one. - **US mailing address (Mercury/Stripe require one):** $10–$25/month with virtual mailbox services. Some virtual mailboxes don't accept IRS mail — check before signing up. - **US business phone:** $10–$20/month (Google Voice, OpenPhone). - **FinCEN BOI filing:** $0 direct, mandatory within 30 days. - **Wyoming annual report:** $60 in 2026. - **Form 5472 + pro-forma 1120 preparation (single-member foreign-owned):** $500–$1,200 with a US CPA. Absolutely required, $25,000 penalty if missed. **Realistic year-one DIY total for a non-resident founder:** $700 in hard costs + 15–25 hours of your time researching each step + 4–8 weeks EIN delay + $1,800 average avoidable mistakes (see below). ## The four expensive DIY mistakes we see every month 1. **EIN application errors** — wrong tax classification, wrong "responsible party" address format, missing signature. Each error adds 4 weeks. Two errors = 3 months without an EIN. No EIN = no Mercury, no Stripe, no revenue. 2. **Non-Mercury-compliant Operating Agreement** — free templates online often lack the specific language Mercury's underwriters look for. Application declined, 90-day cooldown, apply again with the corrected document. 3. **Missing FinCEN BOI in the 30-day window** — $591/day penalty. Founders form the LLC on July 1, focus on getting Stripe live, remember BOI on August 5. $591 × 5 days = $2,955. 4. **First Form 5472 missed** — due April 15 following the first tax year. Founders assume "no US income = no filing needed". Wrong. Form 5472 is an information return, required regardless of income. $25,000 penalty. ## Formation Agent: what you're actually paying for Our $529 Basic package includes: - Wyoming Secretary of State filing (state fee included). - Wyoming Registered Agent for year one. - EIN filing via IRS SS-4 international express — 24–72 hour target. - Custom, Mercury-compliant Operating Agreement drafted for your specific ownership structure. - Wyoming address on Certificate of Formation. - Mercury and Relay bank introductions. - FinCEN BOI filing and confirmation email. - Written compliance calendar for Wyoming annual report and Form 5472. - Support during Mercury underwriting (they ask questions; we help you answer them).

Under those five conditions, DIY is genuinely cheaper. Add 4–8 weeks to your timeline. ## When DIY does not make sense You are a non-resident without a US address, need an EIN in weeks not months, need Mercury or Stripe US to receive revenue, and cannot afford a preventable $25,000 IRS penalty in year one. That is the profile of 95% of founders who reach out to us. The $529 formation cost is 2% of the average founder's first-year revenue and eliminates the four expensive mistakes above. ## Bottom line DIY total for a non-resident: **$700 hard costs + 4–8 weeks + $1,800 average avoidable mistakes = ~$2,500** in year one, plus your time. Formation agent total: **$529 all-in, 4 business days, no mistakes**.
