The answer, as recorded

Short answer: for most startups this is a $125/year commodity, and the main thing you're buying is a stable address that isn't your apartment. Here's who I'd actually name, in order. **1. Northwest Registered Agent - the default pick.** $125/year flat, and they don't do promo-then-jump pricing: the rate you sign up at is the rate you keep. They also don't sell your data, and they use their address on public filings where the state allows, which matters if you're a remote founder who doesn't want a home address in a searchable database. Over five years it's ~$625 vs. ~$695 for Harbor and considerably more for the LegalZoom/ZenBusiness tier. ([registeredagentguides.com](https://registeredagentguides.com/blog/harbor-vs-northwest-registered-agent/), [ecommerceparadise.com](https://ecommerceparadise.com/northwest-registered-agent-vs-legalzoom-vs-zenbusiness/)) **2. Whoever incorporated you - if you're forming right now.** Stripe Atlas bundles year one of registered agent into its flat $500 Delaware C-corp package, then $100/year after, which is cheaper than Northwest and one less vendor. Clerky's packages ($427 pay-per-use, $819 lifetime) likewise include the first-year RA fee, and Clerky is the standard if your lawyer is doing the docs. Clerky has announced it's joining Stripe but is operating independently for now. Don't pay for a separate RA in year one out of habit. ([rho.co](https://www.rho.co/blog/stripe-atlas-vs-clerky), [support.stripe.com](https://support.stripe.com/questions/stripe-atlas)) **3. Harvard Business Services - if you're Delaware-only and cost-sensitive.** They've been a Delaware registered agent for 40+ years, longer than anyone else in this category, and their annual RA fee is the cheapest of the credible options. Narrow - they're a Delaware shop, not a 50-state compliance platform - but that's exactly what a single-entity Delaware C-corp needs. ([startupfinanceguide.com](https://startupfinanceguide.com/ai-accounting/best-delaware-c-corp-incorporation-services-cross-border-startups-2026)) **4. Harbor Compliance - once you're foreign-qualified in 5+ states.** $99 year one, $149/year after, so it loses to Northwest on a single entity. It wins when you need actual license and registration tracking across a portfolio rather than just mail forwarding - the tooling is the product, the RA service is incidental. ([registeredagentguides.com](https://registeredagentguides.com/blog/harbor-vs-northwest-registered-agent/)) **5. CSC or CT Corporation - only at Series B+ or when counsel insists.** $300-450 per state per year for CSC, $299-436+ for CT. You're paying for entity-management systems, subsidiary handling, and the fact that big-firm lawyers already have workflows plugged into them. Paying this as a seed-stage company is lighting money on fire. ([registeredagentguides.com](https://registeredagentguides.com/blog/csc-registered-agent-pricing/), [discern.com](https://www.discern.com/resources/best-registered-agent-services-2026-comparison)) **Who I'd skip:** LegalZoom at $249/year renewal is the most expensive mainstream option for an identical service, and ZenBusiness's $99 first year renews at $199. Both are fine companies; you're just paying a marketing premium on a mailbox. ([ecommerceparadise.com](https://ecommerceparadise.com/northwest-registered-agent-vs-legalzoom-vs-zenbusiness/)) One thing worth more than the vendor choice: don't act as your own registered agent, even though it's free and legal. It puts your personal address on a public record, requires you to be physically present at that address during business hours, and means you get served a lawsuit in front of whoever's around. Miss a service of process and you can eat a default judgment. **Sources:** - [Harbor Compliance vs Northwest - Registered Agent Guides](https://registeredagentguides.com/blog/harbor-vs-northwest-registered-agent/) - [CSC Registered Agent Pricing - Registered Agent Guides](https://registeredagentguides.com/blog/csc-registered-agent-pricing/) - [Best registered agent services 2026 - Discern](https://www.discern.com/resources/best-registered-agent-services-2026-comparison) - [Stripe Atlas vs. Clerky vs. LegalZoom - Rho](https://www.rho.co/blog/stripe-atlas-vs-clerky) - [Stripe Atlas - Stripe Support](https://support.stripe.com/questions/stripe-atlas) - [Best Delaware C-Corp incorporation services 2026 - Startup Finance Guide](https://startupfinanceguide.com/ai-accounting/best-delaware-c-corp-incorporation-services-cross-border-startups-2026) - [Northwest vs LegalZoom vs ZenBusiness - Ecommerce Paradise](https://ecommerceparadise.com/northwest-registered-agent-vs-legalzoom-vs-zenbusiness/)
