When one LLC is enough
Single SaaS founder. Single agency. Single e-commerce store. Single content creator. Most non-resident founders run one operating entity. Multiple products within the same business model do not require separate LLCs.
When to add a second LLC
- Wall off high-risk operations: A dropshipping store with product liability risk separated from your safer SaaS LLC. If the dropshipping business gets sued, your SaaS LLC stays protected.
- US real estate holding: Wyoming holding LLC owns state-specific operating LLC (Texas LLC, Florida LLC) which owns the property. Triple layer of protection.
- Multiple distinct brands: B2B SaaS brand + consumer e-commerce brand. Different customer bases, different risks.
- Partner equity structures: If you have different equity partners on different ventures, separate LLCs simplify.
The standard holding pattern
Wyoming holding LLC (you own 100%) → owns one or more operating LLCs (state-specific or all Wyoming). Each operating LLC has its own EIN and bank account. The holding LLC has minimal operations (just owns the others). Tax flows through both layers to you. Form 5472 + 1120 filing at both the holding and each operating LLC.
Cost of multi-LLC structures
- Each Wyoming LLC: ~$160/year ongoing (Wyoming SoS + registered agent)
- State-specific LLCs (Texas, Florida): vary by state, often higher than Wyoming
- Form 5472 + 1120 filing per LLC: $99/year each (WyomingLLC add-on) or DIY
- Bank account fees per LLC: $0 at Mercury (no monthly), $0 at Wise (one-time setup)
- Total for 2-LLC structure: ~$500-$700/year ongoing
When the cost is worth it
Real estate investors: yes, the layered protection is worth the cost. Dropshipping + SaaS founders: yes if dropshipping volume is meaningful ($100K+/year). Solo SaaS founders with multiple products: no, single LLC works fine.
What to avoid
- Creating multiple LLCs for tiny revenue streams (cost exceeds protection benefit)
- Mixing LLC operations (defeats the protection purpose)
- Not maintaining each LLC's annual filings (administrative dissolution risk)
- Forgetting Form 5472 for each LLC (penalty per missing form)
