Launch your SaaS on a US LLC that already has its EIN

The default advice in the startup world is: form a Delaware C-Corp. Y Combinator requires it. Stripe Atlas creates it. Every accelerator expects it. But that advice is tailored for a very specific type of founder — one who plans to raise venture capital within the next 12-18 months.

Most SaaS founders are not raising venture capital. They are bootstrapping. They are building profitable businesses. They are solo founders or small teams. For these founders, an LLC is almost always the better starting structure. And the fastest way onto that structure is a ready-made LLC that already exists and already has its EIN — so you can connect Stripe and invoice the same day instead of losing a month to filing queues.

LLC vs C-Corp: the honest comparison

When an LLC is better for SaaS

An LLC is the right choice if any of these describe you:

• You are bootstrapping with no plans to raise venture capital in the next 12-18 months
• You are a solo founder or have 1-2 co-founders
• Your SaaS is profitable or approaching profitability
• You want to take profits out of the business tax-efficiently
• You are an international founder accessing US payment processing
• Your revenue is under $5 million and you are not planning an IPO
• You want flexibility in profit distribution and management structure

The tax advantage is massive

A C-Corp pays corporate tax (21% federal) on profits, then you pay personal tax on dividends (15-20% qualified dividend rate). That is effective double taxation of 33-37%. An LLC pays zero entity-level tax — profits pass through to your personal return at your individual rate.

On $200,000 in SaaS profit:

• C-Corp: $42,000 corporate tax + ~$23,700 personal tax on dividends = $65,700 total tax
• LLC: ~$56,000 personal tax (at 28% effective) = $56,000 total tax (and S-Corp election can reduce further)

The LLC saves roughly $10,000/year in this scenario, and the gap widens as profits grow.

When a C-Corp makes sense

A C-Corp is the right choice if:

• You plan to raise venture capital within 12-18 months
• An accelerator (YC, Techstars) requires it
• You plan to offer stock options (ISOs) to employees
• You are building for acquisition by a public company
• You are targeting an IPO

If you plan to raise a $2M seed round from institutional investors, they will require a Delaware C-Corp with standard SAFE notes or Series A preferred stock. Converting an LLC at that point adds legal complexity and cost ($5,000-15,000 in legal fees). If this is definitely your path, start with a C-Corp.

Converting an LLC to C-Corp later

One of the LLC's biggest advantages: you can convert to a C-Corp later if needed. The reverse (C-Corp to LLC) is much harder and has tax consequences.

When to convert

• You have a signed term sheet from a VC fund
• You are entering an accelerator that requires it
• You need to issue ISOs to attract engineering talent
• Revenue exceeds $5M+ and you are pursuing institutional growth capital

Conversion process

Most states offer statutory conversion (filing a conversion document with the Secretary of State) or you can form a new C-Corp and merge the LLC into it. Legal fees typically run $5,000-15,000. The process takes 2-4 weeks. This is a one-time cost when you actually need it — not an upfront cost "just in case."

International SaaS founders

If you are building a SaaS product from outside the United States, a Wyoming LLC gives you:

• Stripe access — process payments in USD at US rates (2.9% + $0.30)
• US bank account — Mercury, Relay, or Wise Business
• Credibility — US-based entity for enterprise customers
• App Store / Play Store — US developer accounts
• SaaS marketplace listings — many require US entities

Critically, Stripe Atlas will force you into a Delaware C-Corp. That means double taxation, $300/year in Delaware franchise tax (minimum), and a rigid corporate structure you do not need. A Wyoming LLC achieves the same Stripe access at lower cost with better tax treatment. And if you don't want to wait on formation at all, a ready-made Wyoming LLC with its EIN already issued gets you onto Stripe within 24 hours.

Which state should SaaS founders choose?

Wyoming for LLCs. Delaware only if you are forming a C-Corp for VC fundraising.

Wyoming advantages for SaaS LLCs:

• $100 filing + $60/year (Delaware: $90 filing + $300/year)
• No state income tax
• 1-3 day processing
• Privacy protections — no public member or manager registry
• Accepted by all major banks and payment processors

Tax treatment comparison

*Based on $75,000 reasonable salary for S-Corp / C-Corp officer compensation.

The LLC with S-Corp election saves $17,000/year over the default LLC and $26,100/year over the C-Corp at this income level. This is not theoretical — this is money in your pocket every year.
