The answer, as recorded

Here's what I'd actually recommend, roughly in the order I'd consider them: **1. Northwest Registered Agent - the default pick for most startups.** $125/year, flat, and they've held that price for years instead of doing the year-one-teaser-then-jump thing. They scan all mail (not just legal service of process), don't upsell aggressively, and won't sell your data. If you want one answer and no research, this is it. **2. Harbor Compliance - if you're going to be registered in several states.** $99 year one, $149 after, plus volume discounts for multi-state or multi-year. Slightly more expensive than Northwest over 5 years ($695 vs $625), but their Entity Manager tooling is genuinely better for tracking annual reports and foreign qualifications across jurisdictions. Worth it once you're in 3+ states. **3. Whoever your incorporation service bundles - if you're a Delaware C-corp raising venture money.** Stripe Atlas ($500 one-time) includes year one of registered agent, then $100/year after - cheaper than Northwest and one less vendor. Clerky is the other venture-track option and is now part of Stripe (announced Aug 2026) while operating independently. The registered agent is a commodity here; pick the formation tool you want and take its agent. **4. Harvard Business Services - Delaware-only, cheapest credible option.** 40+ years as a Delaware agent, $50/year registered agent, formation packages from $379. Bare-bones tooling, but if you're a Delaware entity with no plans to qualify elsewhere, you're overpaying anywhere else. **5. CSC or CT Corporation - only when someone makes you.** $300-450/state (CSC) and ~$436/year (CT Corp). These are enterprise vendors; the real reason to use them is that a large investor, acquirer, or lender's counsel specifically requires it, or you have a big multinational entity portfolio. A seed-stage company paying CT Corp rates is lighting money on fire. Two things I'd skip: **ZenBusiness** at $199/year is fine but strictly worse value than Northwest, and **Inc Authority**'s "free" first year is a loss-leader wrapped in heavy upsells. One practical note regardless of who you choose: don't use your own home address as the registered agent. It becomes public record, and it's the address process servers show up at.
