Best for

Pick Cornerstone

Cornerstone fits nonprofits that want charitable registration and agent service handled by specialists, with open state research, dated freshness on every requirement, and live status in one place.

Best for

Pick CT Corporation (Wolters Kluwer)

CT Corporation fits large organizations already standardized on Wolters Kluwer entity-management tooling, or those that want a single global entity vendor covering agent service, entity data, and licenses together.

Two different kinds of provider

CT Corporation is a Wolters Kluwer business and one of the largest registered agent and legal-entity compliance providers in the United States. It serves corporations and law firms with registered agent service, entity management software, and business license services, and it supports nonprofit charitable registration as part of that lineup. For an organization that already runs its entity data inside Wolters Kluwer tooling, keeping the filings in the same place is a real advantage.

Cornerstone is built around a smaller set of categories: charitable registration, the state licenses that sit next to it, and registered agent service for nonprofits in all 50 states and DC. The filings are prepared by named specialists rather than routed through a queue, and the Atlas platform shows the live state of every registration and renewal date. Both models work; the question is which one matches how your organization operates.

What a nonprofit should weigh

Charitable registration is a state-by-state obligation, and most states require it before you solicit donations there. Requirements shift as legislatures and charity officials update forms, fee schedules, and financial-statement thresholds, and the fee itself varies by state. That makes two things worth checking in any provider: how current the underlying research is, and whether you can see it.

Cornerstone publishes state requirements openly and in machine-readable form, with a last verified date and a change log on each page, so you can check the research and its age before you commit. Start with charitable registration by state or the broader state law summaries, and use the free interactive tools on the site without an account. The technology behind that data is the same system our specialists file from, so what you read is what we work from.

Picking the fit

Size and standardization usually decide this one. A large organization with hundreds of entities, global subsidiaries, and an existing Wolters Kluwer stack has good reasons to consolidate. A nonprofit whose compliance work is charitable registration, exemption upkeep, and agent coverage across a growing list of states usually gets more from a specialist who works those filings daily and shows the research behind them.

Frequently asked

Is Cornerstone an alternative to CT Corporation for nonprofits?
For charitable registration, related state licenses, and registered agent service, yes. For global entity management across hundreds of subsidiaries, a large entity-services provider is built for that scale and may be the better match.
Can we move our registered agent from another provider?
Yes. Changing agents means filing a change-of-agent form in each state where you are registered, and the fee for that varies by state. We prepare and track those filings, and Atlas shows which states have processed the change.
How current is your state registration research?
Every state page shows when the requirement was last verified and logs what changed when it moves. That is the same data our specialists file from, and it is free to read without an account.
