About 66% of Fortune 500 companies are incorporated in Delaware, according to CNBC, but that statistic obscures a more relevant question for founders: does incorporating in Delaware actually make sense for your startup? The honest answer is that Delaware incorporation matters primarily if you plan to raise venture capital from US investors, because VCs overwhelmingly prefer Delaware C-Corps for their standardized corporate law, the Court of Chancery's business expertise, and established legal precedent around SAFEs, convertible notes, and preferred stock.

If you are building a bootstrapped business, an LLC in your home state may be simpler and cheaper. This guide assumes you have decided a Delaware C-Corp is the right structure and compares the services that will actually form the entity for you.

What Incorporation Services Actually Include

Every incorporation service handles the same basic steps:

1. File the Certificate of Incorporation with the Delaware Division of Corporations (state fee: $89 for standard filing, $189 for 24-hour expedited, $1,089 for same-day)
2. Obtain an EIN (Employer Identification Number) from the IRS — required to open a bank account and hire employees
3. Provide a registered agent in Delaware (required by law — every Delaware entity needs a physical address in the state)
4. Generate initial corporate documents — bylaws, board resolutions, stock issuance

The differences between services come down to: how much legal review is included, what ongoing compliance is bundled, and whether the service understands cross-border founders' specific needs (EIN application without a US SSN, bank account opening for non-residents, Form 5472 obligations).

Service Details

Stripe Atlas — Fastest Path to Incorporated

Stripe Atlas is the most widely used incorporation service for tech startups. For $500, you get a Delaware C-Corp, EIN, registered agent (first year), a bank account at Mercury or SVB, and access to Stripe's partner discount network (AWS, HubSpot, etc.). The process takes approximately 1-2 business days for incorporation with expedited filing.

According to Stripe's 2025 Year in Review, Atlas has helped launch startups in over 100 countries. The service is deeply integrated with Stripe's payment processing — founders who use Stripe for revenue can connect their Atlas entity directly.

Strengths: Fastest processing (1-2 business days with expedited). Bank account included (Mercury or SVB). Extensive partner discounts. Largest community (network effects for finding co-founders, investors, and advisors). $500 price includes everything for year one. Limitations: Legal documents are template-based, not attorney-reviewed — adequate for early stage but may need Clerky-level docs before a Series A. Registered agent is only included for year one ($100+/year after). No ongoing bookkeeping or tax compliance. Cross-border founders report that EIN processing can take 4-6 weeks without a US SSN. Post-incorporation compliance (Form 5472, franchise tax) is not handled — you need a separate service.

Best for: Technical founders who want to incorporate quickly, need a bank account immediately, and plan to handle ongoing compliance separately.

Clerky — VC-Track Legal Documents

Clerky was founded by two attorneys from Wilson Sonsini (Silicon Valley's dominant startup law firm) and focuses exclusively on Delaware C-Corp formation for startups planning to raise venture capital. At $799, Clerky is the most expensive incorporation option reviewed, but the premium buys attorney-reviewed documents designed to survive investor due diligence.

Clerky's incorporation package includes board consents, stockholder consents, indemnification agreements, proprietary information and inventions agreements (PIIA), and 83(b) election guidance — documents that other services either skip or generate from templates.

Strengths: Attorney-reviewed documents designed for VC fundraising. Founded by Wilson Sonsini attorneys who understand what investors expect. 83(b) election guidance (critical for founders with restricted stock). PIIA templates. Document management system that tracks all corporate records. Used by many YC and top-tier accelerator companies. Limitations: No bank account setup (provides guides instead). Minimal cross-border support — designed primarily for US-based founders. No ongoing accounting, tax, or compliance services. Post-incorporation, you are on your own for Form 5472, franchise tax, and bookkeeping. More expensive than alternatives. No partner discount network.

Best for: Founders who are already talking to VCs or plan to raise institutional capital within 12 months. The premium for investor-ready legal documents saves money on attorney fees later.

Inkle — Incorporation + Ongoing Cross-Border Compliance

Inkle offers assisted incorporation at $999 — the highest one-time cost — but uniquely bundles it with ongoing cross-border accounting and tax compliance. Where other services incorporate your entity and then leave you to find accountants and tax advisors separately, Inkle continues as your bookkeeping ($99/month), tax filing ($650/year for Form 1120, $100 for franchise tax, $100/form for Form 5472), and registered agent ($5/month) provider.

The company claims approximately 5% of Y Combinator companies in India use the platform, and has been growing revenue 7x year-over-year.

Strengths: Only service that bundles incorporation with ongoing bookkeeping and tax compliance. Lowest ongoing registered agent cost ($5/month vs. $100+/year elsewhere). Purpose-built for cross-border founders (especially India-US). Form 5472 handled as a standard service ($100/form vs. $500+ at most CPAs). Virtual US address available ($15/month). Dissolution service ($350) if the entity needs to be wound down. Limitations: Highest one-time incorporation cost ($999). Not a CPA or law firm — documents are template-based, not attorney-reviewed. India-US corridor is strongest; less proven for other corridors. Smaller team than Stripe Atlas. $99/month bookkeeping tier is limited to $0-2,500 monthly expenses. Less brand recognition than Stripe Atlas or Clerky.

Best for: International founders (especially India-US) who want a single vendor for incorporation, bookkeeping, and tax compliance. The higher upfront cost is offset by lower ongoing costs and reduced vendor management.

doola — Lowest Price Incorporation

doola offers the cheapest incorporation at $297 (Starter) to $597 (Total Compliance), targeting founders who want the lowest possible upfront cost. The Total Compliance package includes EIN, registered agent, operating agreement, and banking setup assistance.

Strengths: Lowest price point ($297). Banking setup included. Bookkeeping add-on available. Simple, streamlined process. Growing ecosystem of post-incorporation services. Limitations: Template-based documents with minimal legal review. Less established than Stripe Atlas or Clerky. Post-incorporation compliance services are add-ons, not bundled. Limited track record with complex cross-border structures. Registered agent quality is less established than Harvard Business Services' 40-year track record.

Best for: Budget-conscious founders who want the cheapest path to a Delaware C-Corp and plan to add services incrementally.

Harvard Business Services — Registered Agent Veterans

Harvard Business Services has operated as a Delaware registered agent for over 40 years — longer than any other service reviewed. Incorporation packages start at $379 and include expedited filing, EIN obtainment, and registered agent service.

Strengths: 40+ years of Delaware registered agent experience. Deep expertise in Delaware Division of Corporations procedures. Annual compliance reminders. Can handle complex entity structures (holding companies, subsidiaries). Most established Delaware presence. Limitations: No technology platform — primarily a traditional service provider. No bank account setup. No bookkeeping or tax compliance. No startup-specific features (SAFEs, cap tables, investor documents). No cross-border specialization. Website and process feel dated compared to Stripe Atlas or Clerky.

Best for: Founders who want the most established, longest-running Delaware registered agent and prefer working with a traditional service provider.

Post-Incorporation: What Most Guides Do Not Tell You

Incorporation is a one-time event. The ongoing compliance is what actually costs money and causes problems. Here is what you need after incorporating:

Within 30 days of incorporation

• Open a US bank account — Required for receiving revenue, paying expenses, and demonstrating the entity is operational. Mercury (for Stripe Atlas users) or apply directly at Mercury, Relay, or a traditional bank.
• Issue stock to founders — Using a board consent and stock purchase agreement. File an 83(b) election with the IRS within 30 days of stock grant if stock is subject to vesting (this is irrecoverable if missed).

Annually (every year the entity exists)

• Delaware franchise tax — Due March 1. Minimum $400 via Assumed Par Value method. According to the Delaware Division of Corporations, late filing incurs a $200 penalty plus 1.5% monthly interest.
• Form 1120 (or pro-forma 1120) — Due April 15 for calendar-year entities. Even zero-revenue corporations must file.
• Form 5472 — Due with Form 1120 for any 25%+ foreign-owned corporation. $25,000 penalty per failure, per the IRS. This catches many international founders by surprise.
• Registered agent fee — Annual renewal ($5/month with Inkle to $300+/year with traditional providers).

When raising venture capital

• Legal document review — If you used template documents from Stripe Atlas, doola, or Inkle, an attorney should review them before a priced round. Budget $2,000-5,000.
• Cap table management — Services like Carta, Pulley, or AngelList handle SAFEs, convertible notes, and equity. Not included in any incorporation service.

Limitations and What We Don't Know

No incorporation service has published data on entity longevity, compliance rates, or customer satisfaction in peer-reviewed form. Claims about the number of startups incorporated are self-reported and not independently verified.

The quality of template-based legal documents (used by Stripe Atlas, doola, Inkle) has not been systematically compared to attorney-reviewed documents (Clerky) in terms of downstream legal outcomes. Most startups will never face a legal challenge to their incorporation documents, making it difficult to assess whether the Clerky premium produces measurably better outcomes.

Cross-border EIN processing times vary unpredictably. The IRS does not publish average processing times for EIN applications from foreign nationals, and founders report waits ranging from 1 week to 8 weeks depending on application method (online vs. fax) and current IRS backlog.

Frequently Asked Questions

Should I use my incorporation service for ongoing accounting too?

It depends on the service. Inkle is the only service reviewed that provides both incorporation and ongoing accounting/tax compliance. If you use Stripe Atlas, Clerky, doola, or Harvard Business Services for incorporation, you will need to find a separate bookkeeping and tax service afterward. Many founders use their incorporation service for the one-time setup and then switch to a platform like Inkle ($99/month), Fondo ($299/month), or Pilot ($349/month) for ongoing compliance.

Is Stripe Atlas worth $500 when doola charges $297?

For most founders, yes. The $203 difference buys a significantly smoother experience: faster processing, automatic bank account setup (Mercury or SVB), and access to Stripe's partner discount network. The partner discounts alone (AWS credits, HubSpot credits) often exceed the price difference. doola is the better choice if you are optimizing purely for upfront cost and plan to handle banking and partner relationships independently.

Do I really need a registered agent?

Yes — it is a legal requirement in Delaware. Every entity incorporated in the state must maintain a registered agent with a physical Delaware address. The agent receives legal service of process, state correspondence, and tax notices on your behalf. Costs range from $5/month (Inkle) to $300+/year (traditional providers). All five services reviewed include at least one year of registered agent service.

What is Form 5472 and why does it matter?

IRS Form 5472 must be filed by any US corporation with 25% or more foreign ownership, reporting transactions between the corporation and its foreign owners or related parties. According to the IRS, the penalty for not filing is $25,000 per form, per year. The form cannot be e-filed. If you are a non-US person who owns 25%+ of your Delaware C-Corp — which is almost every international founder — this filing is mandatory even if the company has zero revenue. Of the incorporation services reviewed, only Inkle handles this filing as an ongoing service ($100/form). With other services, you need a CPA who understands international reporting.
