How to Fill Out the Sponsored Cell Captive Application (w/Examples) + FAQs

The Sponsored Cell Captive Application is the form a sponsor or cell participant files with a state insurance department to create or add a protected cell inside a sponsored captive insurance company, so that one company can isolate the risks of separate participants in legally walled-off cells. A sponsor must file it whenever a new cell is added, because under laws like Utah’s sponsored captive statute, the addition of each new protected cell does not take effect without the commissioner’s prior written approval.

Getting this form right matters because regulators review for funding adequacy, risk separation, and a credible business plan before they let a single dollar of premium flow into a cell. States process these filings fast when they are clean, and Connecticut targets approval of a captive application in just 1 to 4 weeks, but a missing pro forma, a weak participation agreement, or a vague business plan can push that timeline out by months.

What the Form Is and Who Must File It

A Sponsored Cell Captive Application is a regulatory filing that asks a state’s insurance commissioner to approve a new protected cell, the participant who will use it, and the business that cell will write. In Nevada, this is the Protected Cell Application for Sponsored Captives, filed with the Division of Insurance. The form sits inside a larger framework: the sponsored captive itself already holds a Certificate of Authority, and each new cell rides on that license through its own application and participation agreement.

The people who file this form are usually professionals, not the public. A sponsor (often an insurer, reinsurer, captive management firm, or holding company) files to launch a new cell, and a participant (the business whose risk the cell insures) files or co-signs to join. Under Utah law, the interest holders of a sponsored captive are limited to the participants and the sponsors, which means stray third parties cannot simply buy into a cell.

You must file when you create a cell, add a participant, or materially change a cell’s business plan. A participant contract does not take effect without the commissioner’s prior written approval, so skipping the filing makes the cell legally inert even if money has changed hands. The form solves the core problem of risk separation: it documents, on paper, that each cell’s assets are not chargeable with the liabilities of any other cell or the sponsor’s general account.

A key entity to know is the captive manager, the licensed firm that usually prepares and submits the form on the participant’s behalf. The state insurance commissioner is the decision-maker, the sponsored captive is the legal shell, and the cell is the compartment. Each relates to the next like floors in a building that share an address but never share a flood.

Before You Start: Documents and Information You Need

Gather everything below before you open the form, because regulators reject incomplete packages and the clock often does not start until the filing is complete. Maine’s statute, for example, gives the superintendent 30 days just to decide whether an initial filing is even complete. A missing item resets your wait.

Here is your pre-filing checklist:

The sponsored captive’s Certificate of Authority number, because the cell rides on the existing license and the state cross-references it. Missing it stalls the file at intake.
The legal name and entity type of the participant (corporation, LLC, partnership, trust, or association), since Utah law limits participants to these entity types. The wrong entity type triggers a rejection.
A federal Employer Identification Number (EIN) for the participant, because the state and IRS both track the cell’s tax identity. A typo here mismatches every downstream filing.
A cell-specific business plan that describes the coverage, premium, and projected losses, since the commissioner approves the plan, not just the form. A vague plan is the top cause of delay.
A pro forma financial projection, usually five years, showing premiums, losses, expenses, and surplus. Without it, the regulator cannot judge solvency.
An actuarial feasibility study or opinion from an independent actuary who is not an employee of the company or an affiliate. An in-house actuary’s opinion can be disallowed.
The proposed cell capitalization amount and its source (cash, irrevocable letter of credit, or trust). Underfunding stops approval cold.
Biographical affidavits for the cell’s key managers and officers, because the state vets the people behind the money. A blank affidavit halts background review.
The participation agreement (also called the participant contract) that governs the cell’s rights and limits. The cell cannot operate until the commissioner approves this contract.
A Uniform Consent to Service of Process, which Nevada lists among its captive application forms. Without it, the state has no legal way to serve the entity.

Collecting these first turns a multi-week scramble into a single clean submission.

Where to Get the Form and How to Access It

You get the official form from the captive insurance section of your domicile state’s insurance department, never from a third-party reseller. Nevada posts its Protected Cell Application for Sponsored Captives directly on its Forms and Resources page, alongside the Business Plan Template and the Uniform Consent to Service of Process. Always download the current edition, because an outdated form can carry retired field labels that confuse the reviewer.

Other states route the request differently. Connecticut handles new cells through a Cell Business Plan Change Request filed with the Insurance Department, while Tennessee publishes a Protected Cell Captive Individual Cell Application on its captive applications page. Georgia funnels everything through its GIMS Portal, where you upload the application, fees, and documents in one place.

If your form shows a revision date in the footer, confirm it matches the current version before you type a single entry, because regulators reject superseded editions at intake. When a state offers no public PDF, you request it by email; Nevada, for example, directs filers to contact captives@doi.nv.gov for certain forms. The captive manager usually handles this access step, but the participant should keep a copy of whatever edition was used.

Step-by-Step: How to Fill Out the Sponsored Cell Captive Application Line by Line

Below is a field-by-field walkthrough using the standard sections that appear on a sponsored cell application across domiciles. Use the exact box numbers and labels printed on your state’s form, since labels vary slightly. Type every entry in the format the form requests, and keep your sample entries consistent across every attachment.

Section 1: Name of the Sponsored Captive Insurance Company

This field asks for the full legal name of the existing sponsored captive that will host the new cell. Enter the name exactly as it appears on the captive’s Certificate of Authority, in the same capitalization, because the state matches this string against its license database. Summit Sponsored Captive, LLC writes its name precisely that way, with the comma and the LLC intact.

A common nuance is the difference between the captive’s legal name and its trade or “doing business as” name; always use the legal name here, not the brand. The most frequent mistake is entering the cell’s name in this box instead of the parent captive’s name, which makes the reviewer unable to attach the cell to a valid license and triggers a deficiency notice. Many filers wrongly believe this field identifies the new cell, when it actually identifies the umbrella company the cell lives inside.

Section 2: Certificate of Authority Number of the Sponsored Captive

This field asks for the license number already issued to the sponsored captive. Enter the number exactly as printed on the certificate, including any leading zeros or letter prefixes, because the digits are matched character for character. Summit Sponsored Captive, LLC enters NV-CAP-001847 with no spaces.

If your captive was recently approved and the number has not yet posted, attach the approval letter and write Pending – see attached approval letter rather than guessing. The most common mistake is transposing two digits, which routes the cell filing to the wrong company file or to no file at all and silently delays review. People often assume this number is the same as the captive’s state business registration number, but the Certificate of Authority number is a separate insurance license identifier.

Section 3: Name of the Proposed Protected Cell

This field asks what the new cell will be called inside the captive. Use a clear, unique label, often the participant’s name plus “Cell,” and follow any numbering convention the state uses. Cell 7 – Riverside Logistics is a clean entry that ties the cell number to the participant.

A useful nuance: if your state assigns the cell number rather than letting you choose it, leave the number portion blank and write only the descriptive name. The most common mistake is reusing a cell name that already exists in the captive, which creates an accounting collision because each cell must be accounted for separately. Filers sometimes think the cell name is cosmetic, but it becomes the permanent ledger label the regulator uses for every future financial report.

Section 4: Participant Legal Name and Entity Type

This field asks who will use the cell to insure their own risk, and what kind of legal entity they are. Enter the participant’s full legal name and check or write the entity type, which must be an eligible entity such as a corporation, LLC, partnership, trust, or association. Riverside Logistics, Inc. selects Corporation as its entity type.

A common edge case is a participant that is itself the sponsor, which several statutes expressly allow, so check the box that fits even if it feels redundant. The most frequent mistake is naming an individual person as the participant, because a sponsored cell insures business entities and their own risks, not personal exposures, and this draws an immediate rejection. People often misread this box as asking for the cell manager; it asks for the insured business, the entity whose losses the cell will pay.

Section 5: Participant Federal Employer Identification Number (EIN)

This field asks for the participant’s nine-digit federal tax ID. Enter it in the standard XX-XXXXXXX format with the dash, because the state and IRS both key on this number. Riverside Logistics, Inc. writes 47-3920185 in the box.

If the participant is a foreign entity without an EIN, attach an explanation and the alternate tax identifier rather than leaving the field blank. The most common mistake is entering the sponsor’s EIN instead of the participant’s, which scrambles the cell’s tax identity and can misroute premium tax reporting. Many filers believe the cell gets its own separate EIN, but the cell usually reports under the participant’s or the captive’s tax identity unless the state directs otherwise.

Section 6: Lines of Coverage and Risks to Be Insured

This field asks exactly what the cell will insure. List each line of coverage in plain terms, such as general liability, workers’ compensation deductible reimbursement, or property, and tie each to the participant’s actual exposure. Riverside Logistics, Inc. enters Auto liability and physical damage for owned commercial fleet.

A key nuance: a participant must insure only its own risks unless the commissioner approves otherwise, so do not list third-party or consumer risk here without prior approval. The most common mistake is listing vague “all business risks” language, which forces the reviewer to send the file back for specifics and burns a review cycle. Filers sometimes assume they can add lines later without notice, but a material change to coverage is itself a filing the commissioner must approve.

Section 7: Projected Premium Volume

This field asks for the annual premium the cell expects to write. Enter a specific dollar figure, usually the first-year projection, and make sure it matches your pro forma to the dollar. Riverside Logistics, Inc. enters $640,000 for year one.

A useful edge case is a ramp-up plan where premium grows over five years; enter year one here and show the full curve in the pro forma. The most common mistake is entering a number that does not reconcile with the attached financials, which signals sloppiness and invites deeper scrutiny of the whole file. People often think a higher premium projection looks stronger, but an inflated figure that the actuarial study cannot support actually weakens the application.

Section 8: Proposed Cell Capitalization and Source of Funds

This field asks how much capital the cell will hold and where that money comes from. Enter the dollar amount and identify the source as cash, an irrevocable letter of credit, or a trust, because each cell must be funded enough to stand on its own. Riverside Logistics, Inc. enters $250,000 cash, plus a $400,000 irrevocable letter of credit.

A critical nuance: if you use a letter of credit, statutes such as Utah’s require it to be issued by a qualifying bank, so name a bank that is chartered in-state, a Federal Reserve member, or otherwise acceptable to the commissioner. The most common mistake is underfunding the cell relative to projected losses, which guarantees a denial because the regulator cannot approve an impaired cell. Filers often believe the sponsor’s capital backs every cell, but each cell’s assets are walled off and not chargeable with another cell’s liabilities, so each must fund itself.

Section 9: Business Plan Attachment

This field asks you to attach a cell-specific business plan and usually to confirm it is included. Check the box and label the attachment clearly, because in many states the commissioner approves the plan itself, not merely the cover form. Riverside Logistics, Inc. attaches a document titled Cell 7 Business Plan – Riverside Logistics and checks Attached.

A common nuance is reusing the captive’s master business plan; that is not enough, since the cell needs its own plan tailored to its lines and premium. The most frequent mistake is attaching a generic template with placeholder text still inside, which reads as unfinished and stops the review. People often think the business plan is a formality, but a cell business plan change is the actual document Connecticut approves before a cell can operate.

Section 10: Actuarial Feasibility Study and Opinion

This field asks you to attach an actuarial study supporting the premium and reserves. Confirm the study is signed by an independent actuary, because statutes require an opinion from an actuary who is not an employee of the company or an affiliate. Riverside Logistics, Inc. attaches an opinion signed by an outside credentialed actuary and notes the firm’s name.

A useful edge case: for a very small or low-risk cell, some states accept a lighter feasibility memo, but confirm this with the regulator before relying on it. The most common mistake is submitting projections an in-house actuary prepared, which the commissioner may disallow. Filers sometimes believe any actuary will do, but independence is the point, since a captive owner’s own staff has an interest in optimistic numbers.

Section 11: Participation Agreement Attachment

This field asks you to attach the participation agreement (participant contract) and confirm it is included. Check the box and ensure the agreement spells out the cell’s separation, dividends, and exit terms, because the contract does not take effect without the commissioner’s prior written approval. Riverside Logistics, Inc. attaches a signed Cell 7 Participation Agreement.

A key nuance is the asset-transfer language: the agreement should bar transfers between cells without consent, mirroring the statute’s protection of each cell’s assets. The most common mistake is submitting an unsigned draft, which the regulator cannot approve, leaving the cell legally unable to write a single policy. People often assume a handshake or side letter suffices, but only the approved written participation agreement gives the cell legal force.

Section 12: Biographical Affidavits and Service Providers

This field asks you to identify and attach affidavits for the cell’s key people and to name service providers like the captive manager and actuary. Attach a biographical affidavit for each officer, director, or key manager, because the state vets the individuals controlling the money. Riverside Logistics, Inc. attaches affidavits for its two officers and names its licensed captive manager.

A common edge case arises when a key person already has an affidavit on file from a prior filing; confirm whether the state lets you reference it instead of refiling. The most frequent mistake is leaving a blank or unsigned affidavit, which halts the background review and freezes the entire application. Filers often think only the participant’s owners need affidavits, but the regulator wants every individual with real control over the cell’s operations.

Section 13: Uniform Consent to Service of Process

This field asks the entity to consent to being legally served through the state. Sign and attach the Uniform Consent to Service of Process, because it gives the state a reliable way to deliver legal notices. Riverside Logistics, Inc. signs the consent naming the state insurance commissioner as its agent for service.

A useful nuance: out-of-state participants especially must complete this, since they have no in-state office to receive process. The most common mistake is skipping it because it feels like boilerplate, which leaves a gap the state will not approve around. People often misread this as waiving their legal rights, but it only sets the channel through which legal documents reach the entity.

Section 14: Authorized Signature and Date

This final field asks an authorized officer or the sponsor’s representative to sign and date the form. Sign in ink or with an accepted e-signature, print the name and title beneath, and write the date in MM/DD/YYYY format. Maria Chen, President, signs and writes 06/02/2026 in the date box.

A common edge case is the captive manager signing on the participant’s behalf; confirm the form allows an agent signature and attach authority if it does. The most frequent mistake is an undated or wrong-titled signature, which makes the filing defective and sends it back. Filers sometimes believe any employee can sign, but only a person with binding authority for the entity can validly execute the application.

How to File the Completed Form

You can file the completed application through whichever channels your domicile offers, and most states accept more than one. Confirm the channel before you submit, because filing in the wrong place restarts your wait. Keep proof of every submission.

Online portal. Georgia requires uploads through its GIMS Portal, where you attach the application, forms, and fees together. Save the portal confirmation screen and reference number as your proof of filing; processing then runs on the state’s published review timeline.
Email. Nevada directs filers to its captive team and accepts certain forms by email at captives@doi.nv.gov, listed on its forms page. Request a read receipt or confirmation reply and keep the sent message as proof.
Mail. Connecticut’s department accepts filings at its Hartford P.O. Box, P.O. Box 816, Hartford, CT 06142-0816. Send by tracked or certified mail and keep the tracking receipt as proof of the filing date.
Fees and payment. Connecticut charges an $800 application fee for a new captive and then bills a $375 initial license fee, though it charges no application fee to add a cell to an existing sponsored captive; pay by the method the department specifies, usually check or portal payment.

Whatever the channel, the expected processing window is short for a clean file, with Connecticut aiming for 1 to 4 weeks. Always retain a complete copy of everything you sent.

What Happens After You File

After you submit, the department checks the package for completeness before substantive review even begins. Maine’s superintendent has 30 days just to decide whether the filing is complete, so an early deficiency notice is common and not a denial. Respond fast, because the review clock often pauses until you cure the gap.

If the file is clean, the regulator moves to substantive review of the business plan, pro forma, capitalization, and people. In Connecticut, the department then issues a Cell Business Plan Change Request approval before the cell may operate, and only after that approval are the cell’s insurance operations authorized. The commissioner’s prior written approval is the legal switch that turns the cell on.

Once approved, the cell can bind coverage and accept premium, but new duties begin immediately. The sponsored captive must annually file financial reports with accounting statements detailing each cell’s experience, and it must notify the commissioner in writing within 10 business days if any cell becomes insolvent. Approval is the start of an ongoing relationship, not the end of one.

Mistakes to Avoid When Filling Out the Form

Each item below names a specific error and the concrete harm it causes.

Entering the cell’s name where the parent captive’s legal name belongs, which prevents the reviewer from attaching the cell to a valid license.
Transposing digits in the Certificate of Authority number, which routes the filing to the wrong company record and silently delays it.
Naming an individual person as the participant, which draws an immediate rejection because cells insure business entities and their own risks.
Using the sponsor’s EIN instead of the participant’s, which scrambles the cell’s tax identity and misroutes premium tax reporting.
Listing vague “all business risks” coverage, which forces a deficiency notice for specifics and burns a full review cycle.
Underfunding the cell relative to projected losses, which guarantees denial since the regulator cannot approve an impaired cell.
Naming a letter-of-credit bank that does not qualify under statute, which invalidates the funding and stalls approval.
Submitting projections from an in-house actuary, which the commissioner may disallow for lack of independence.
Attaching an unsigned participation agreement, which leaves the cell legally unable to write any policy.
Leaving a biographical affidavit blank or unsigned, which freezes the background review for everyone on the filing.
Skipping the Uniform Consent to Service of Process, which leaves a legal gap the state will not approve around.
Reconciling the projected premium number with nothing, so the form and the pro forma disagree and invite deeper scrutiny.
Submitting the captive’s master business plan instead of a cell-specific plan, which the regulator will not accept as sufficient.
Filing through the wrong channel, which can restart the review clock from zero.

Do’s and Don’ts

These quick rules capture the habits that keep an application moving.

Do:

Do download the current form edition from the state insurance department, because an outdated form carries retired labels that confuse reviewers.
Do match the captive’s legal name and license number exactly, because the state matches both character for character.
Do attach a cell-specific business plan, because the commissioner approves the plan and not just the cover form.
Do use an independent actuary, because statutes can disallow opinions from in-house staff.
Do fund the cell to support its projected losses, because each cell must stand on its own walled-off assets.
Do keep dated proof of filing, because the submission date drives every downstream deadline.

Don’t:

Don’t name an individual as the participant, because only eligible business entities may participate.
Don’t transfer assets between cells without consent, because the statute protects each cell from the others.
Don’t inflate premium projections, because numbers the actuary cannot support weaken the whole file.
Don’t submit unsigned attachments, because the regulator cannot approve a draft.
Don’t treat the consent to service as optional, because the state needs a legal channel to reach the entity.
Don’t assume coverage can be expanded later without notice, because material changes require their own approval.

Pros and Cons of Filing on Your Own vs. With a Captive Manager

Most participants file through a licensed captive manager, but some larger sponsors handle it in-house. The comparison below frames the trade-off.

Pros of using a captive manager:

A manager knows each state’s exact form edition, which avoids rejected outdated filings.
A manager coordinates the actuary, bank, and attorney, which keeps attachments consistent.
A manager spots underfunding before submission, which prevents a denial.
A manager has standing relationships with regulators, which can speed deficiency cures.
A manager handles ongoing annual reports, which protects the cell’s good standing after approval.

Cons of using a captive manager:

A manager charges fees, which adds cost to a small cell’s budget.
A manager adds a layer between the participant and the regulator, which can slow direct questions.
A manager may use standardized templates, which can feel generic for an unusual risk.
A manager’s calendar may not match your urgency, which can delay a rushed filing.
A manager relationship creates dependency, which complicates switching providers later.

Sponsored Cell Captive	Pure (Single-Parent) Captive
One captive hosts multiple participants in separate cells	One captive insures only its single owner’s risks
Participant rents a cell and adds it by application	Owner forms a standalone captive from scratch
Each cell’s assets are walled off from other cells	All risk and surplus sit in one shared account
Faster, lower-cost entry for one participant	Higher cost and full regulatory build-out
Sponsor and participants are the only interest holders	The single parent is the sole owner

FAQs

Do I need to file a new application for every cell I add?

Yes. The addition of each new protected cell requires the commissioner’s prior written approval, so every cell needs its own application or cell business plan change request before it can operate.

Do I write the cell’s name in the box that asks for the company name?

No. Box 1 asks for the parent sponsored captive’s full legal name as it appears on its Certificate of Authority, while the cell’s name goes in the separate proposed-cell-name field.

Do I enter the participant’s EIN or the sponsor’s EIN in the EIN box?

No. You enter the participant’s nine-digit EIN in XX-XXXXXXX format, not the sponsor’s, because that box establishes the cell participant’s tax identity.

Do I list every line of coverage, or can I write “all risks”?

No. You must list each specific line of coverage tied to the participant’s own exposure, because vague “all risks” language triggers a deficiency notice and a delay.

Do I have to use an outside actuary?

Yes. States generally require an opinion from an independent actuary who is not an employee of the company or an affiliate, and an in-house opinion may be disallowed.

Do I need to fund each cell separately?

Yes. Each cell’s assets are not chargeable with another cell’s liabilities, so each cell must hold enough capital to support its own projected losses.

Do I pay an application fee to add a cell to an existing sponsored captive?

No. Connecticut, for example, charges no application fee to add a cell to a licensed sponsored captive, though fee rules vary, so confirm with your domicile.

Do I file the form online or by mail?

Yes. Most states accept at least one of online portal, email, or mail, and some accept several, so use the channel your domicile publishes and keep proof.

Do I need the commissioner’s approval before the participation agreement takes effect?

Yes. A participant contract does not take effect without the commissioner’s prior written approval, so the cell cannot bind coverage until that approval issues.

Do I have to attach a separate business plan for the cell?

Yes. A cell-specific business plan is required, because the master captive plan does not describe the new cell’s lines, premium, and projected losses.

Do I need to notify the state if a cell later becomes insolvent?

Yes. The captive must notify the commissioner in writing within 10 business days of a cell that is insolvent or unable to meet its claim or expense obligations.

Do I write the date as MM/DD/YYYY in the signature block?

Yes. Use MM/DD/YYYY format and have an officer with binding authority sign, because an undated or wrong-titled signature makes the filing defective.

Do I need a Uniform Consent to Service of Process if the participant is out of state?

Yes. Out-of-state participants especially must file the consent, because the state needs a reliable in-state channel to deliver legal notices.

Do I have to refile a biographical affidavit if one is already on file?

No. Some states let you reference an affidavit already on file from a prior filing, but confirm this with your domicile before relying on it.
