How to Get an FFL in Colorado

Colorado's firearms regulatory landscape has transformed dramatically in 2024–2025. A new state dealer permit, stricter background check rules, a 3-day waiting period, a 21+ minimum purchase age, and an upcoming semi-automatic rifle permit-to-purchase system have added significant compliance layers for FFLs. Whether you're opening a gun store along the Front Range, a shop in a mountain town, or a home-based dealership on the Eastern Plains — here's everything you need to navigate the current requirements.

Eligibility Requirements

Colorado now requires two levels of dealer licensing: the federal FFL from ATF and — as of July 1, 2025 — a state dealer permit from the Colorado Department of Revenue. You must hold both to legally operate as a firearms dealer in Colorado.

Federal Requirements (All States)

  • At least 21 years old
  • U.S. citizen or legal permanent resident
  • Not under indictment or convicted of a crime punishable by imprisonment exceeding one year
  • Not a fugitive from justice
  • Not an unlawful user of or addicted to any controlled substance
  • Not adjudicated as mentally defective or committed to a mental institution
  • Not dishonorably discharged from the Armed Forces
  • Not subject to a court order restraining you from harassing, stalking, or threatening an intimate partner or child
  • Not convicted of a misdemeanor crime of domestic violence
  • Have premises for conducting business
  • Not prohibited from possessing firearms under federal, state, or local law

Colorado-Specific Eligibility Notes

  • State dealer permit required — As of July 1, 2025, all FFLs must obtain a state permit from the Colorado Department of Revenue, Firearms Dealer Division. Operating without a permit is an unclassified felony punishable by a fine of up to $250,000.
  • No adverse licensing actions — You must not have had a federal, state, or local firearms license revoked, suspended, or denied within the prior 3 years
  • No firearms law violations — No state or federal firearms law violations in the 3 years before applying
  • Employee background checks — All employees who handle firearms or process transfers must undergo fingerprint-based background checks through CBI before employment and annually thereafter
  • Business registration — Register with the Colorado Secretary of State and the Colorado Department of Revenue
  • Local zoning compliance — Colorado has 64 counties. Since 2021, there is no statewide firearm preemption — local governments can enact firearms ordinances more restrictive than state law. Denver and Boulder have additional local restrictions.
🚨 Rapid Legislative Changes — Stay Current

Colorado passed 12 gun bills in 2025 alone, with more changes taking effect in 2026. Key upcoming deadlines include: August 1, 2026 — permit-to-purchase required for specified semi-automatic firearms (SB25-003); July 1, 2026 — minimum age 21 to purchase ammunition, ammunition must be stored behind counters or in locked displays. Dealers must actively monitor the Colorado General Assembly and CBI updates.

FFL Types & Cost Breakdown

The type of FFL you apply for depends on your intended business activities. Most Colorado gun stores apply for a Type 01 license. Note the new state dealer permit fee effective July 2025.

📋 NFA Items in Colorado

Colorado is NFA-friendly compared to states like New York and Illinois. Suppressors, SBRs, SBSs, and AOWs are legal to own and transfer in Colorado with proper NFA registration. Machine guns manufactured before May 19, 1986 are transferable with NFA compliance. If you plan to deal in NFA items, you'll need the appropriate SOT (Special Occupational Tax) designation on top of your FFL.

Step-by-Step Application Process

1

Register Your Business & Confirm Zoning

Establish your business entity with the Colorado Secretary of State, obtain an EIN from the IRS, and register with the Colorado Department of Revenue for state sales tax. Confirm your premises meets local zoning requirements — since Colorado repealed statewide preemption in 2021, local municipalities can impose their own restrictions. Denver, Boulder, and other Front Range cities may have additional ordinances affecting firearms businesses.

2

Choose Your FFL Type & Complete ATF Form 7

Select the FFL type that matches your business activities, then download and complete ATF Form 7 (5310.12). Provide complete details about your business, all responsible persons, and your premises. Errors are the #1 cause of delays.

3

Complete Fingerprint Cards & Photographs

Each responsible person must complete two FBI fingerprint cards (FD-258) and provide two 2×2 passport-style photographs. In Colorado, fingerprinting is available through local police departments, sheriff's offices, and authorized vendors.

4

Submit Application & Fee

Mail the completed Form 7, fingerprint cards, photographs, and your application fee to the ATF Federal Firearms Licensing Center in Atlanta, GA.

5

Notify Your Chief Law Enforcement Officer (CLEO)

Send a copy of your completed ATF Form 7 to your local CLEO — typically your county sheriff or municipal chief of police. Colorado has 64 counties. This is notification only — CLEO approval is not required.

6

Complete the ATF Interview & Inspection

An ATF Industry Operations Inspector (IOI) will schedule a premises visit. They'll verify your identity, inspect storage and security, and confirm your understanding of federal and Colorado firearms laws — including 4473 procedures, A&D bound book requirements, CBI InstaCheck, the 3-day waiting period, and multiple sale reporting.

7

Apply for Colorado State Dealer Permit

After receiving your FFL, apply for the mandatory state dealer permit from the Colorado Department of Revenue, Firearms Dealer Division. Fee: $400 (valid for 3 years, may increase up to $25/year). You must hold a valid FFL, have no adverse licensing actions in the prior 3 years, and have no firearms law violations in the prior 3 years. The DOR must act on applications within a defined timeline.

8

Register with CBI InstaCheck & Set Up Compliance

Send a copy of your FFL (with visible ATF seal) and business phone number to cbi_ffl@state.co.us to establish your CBI InstaCheck account. Complete employee fingerprint background checks ($39.50 each through CBI). Establish your A&D Bound Book, post required safe storage signage, and implement Bravo E4473 for digital 4473 processing and waiting period tracking from day one.

Colorado-Specific Requirements

Colorado's firearms regulatory environment has shifted significantly toward stricter regulation since 2021. The combination of repealed preemption, universal background checks, a 3-day waiting period, a 21+ purchase age, the new state dealer permit, and upcoming semi-automatic rifle restrictions creates a compliance environment that is rapidly approaching states like Washington and California in complexity.

Key State Laws Affecting FFLs

  • CBI InstaCheck — State POC system — Colorado is a full state point-of-contact. All background checks go through the CBI InstaCheck Unit, which checks both state and federal (NICS) databases. Fee: $15 per check (effective March 1, 2025).
  • Must wait for CBI "proceed" — Under HB21-1298 (effective June 19, 2021), Colorado dealers must wait for a CBI "proceed" response before transferring any firearm. The federal 3-business-day default does not apply in Colorado. If CBI delays the check, you wait until CBI approves — no automatic transfers after 3 days.
  • 3-day waiting period — Under HB23-1219 (effective October 1, 2023), it is unlawful to transfer a firearm to a purchaser until 3 days after the dealer initiates the background check. This applies to all firearms. You still need CBI approval — the 3-day wait is a minimum, not a maximum.
  • Age 21 for all purchases — Under SB23-169 (effective November 27, 2024, following 10th Circuit ruling), the minimum age to purchase any firearm — including rifles and shotguns — is 21 years old.
  • Universal background checks — All firearms transfers, including private sales, must go through an FFL with a CBI InstaCheck. Dealers may charge up to $10 for facilitating private transfers.
  • 15-round magazine limit — Magazines holding more than 15 rounds are prohibited. Magazines owned before July 1, 2013 are grandfathered.
  • No constitutional carry — Colorado is a shall-issue state. Concealed carry requires a Concealed Handgun Permit (CHP) from your county sheriff. As of July 1, 2025, new applicants must complete 8 hours of in-person training with live-fire instruction.
  • Open carry legal (mostly) — Open carry is permitted in most of Colorado without a permit. Denver bans open carry. Other municipalities may restrict it. Federal buildings, K-12 schools, and courthouses are prohibited.
  • Red flag law (ERPO) — Colorado's Extreme Risk Protection Order law allows police, family members, household members, health care providers, educators, and district attorneys to petition for temporary firearm removal from individuals deemed an extreme risk.
  • Ghost gun ban — Effective January 1, 2024, it is illegal to possess, transport, sell, or buy unserialized firearms or frames/receivers.
  • No statewide preemption (since 2021) — Local governments can enact firearms ordinances more restrictive than state law. CHP holders are generally exempt from local carry restrictions, but dealers must be aware of local ordinances affecting their business operations.
  • Lost/stolen reporting for dealers — Dealers must report stolen firearms within 48 hours of discovery.
⚠️ Coming August 1, 2026 — Semi-Automatic Rifle Permit-to-Purchase (SB25-003)

Effective August 1, 2026, purchasers of "specified semiautomatic firearms" (most semi-automatic firearms accepting detachable magazines) will need a Firearm Safety Course Eligibility Card issued by their county sheriff. This requires a safety class (4 hours for hunter education graduates, 12 hours for others), live-fire training, a background check, and fees to Colorado Parks & Wildlife. Without this card, buyers can only purchase models with fixed magazines limited to 15 rounds. Dealers will need to verify this card before completing transfers of specified firearms. Gun rights groups argue this is a de facto assault weapons ban and legal challenges are expected.

State Dealer Permit — HB24-1353

HB24-1353, effective July 1, 2025, created Colorado's first mandatory state firearms dealer permit. This is a major change — prior to this law, Colorado did not require any state-level dealer license beyond the federal FFL.

Permit Requirements

  • Application — Apply through the Colorado Department of Revenue, Firearms Dealer Division
  • Fee$400 (valid for 3 years). DOR may increase the fee by up to $25 per year.
  • Prerequisites — Must hold a valid FFL; no adverse licensing actions in prior 3 years; no firearms law violations in prior 3 years
  • Penalty for non-compliance — Operating without a state permit is an unclassified felony punishable by a fine of up to $250,000
  • DOR inspections — The DOR has inspection authority over permitted dealers

Employee Requirements (Also HB24-1353)

  • Background checks — All employees who handle firearms or process transfers must undergo fingerprint-based background checks through CBI before beginning work and annually thereafter. Fee: $39.50 per check (includes $11.25 FBI fee).
  • Training — Employees must complete required training on federal and state laws
  • Age requirement — Employees handling firearms must be at least 21 years old
  • Firearms must be secured — Firearms on premises must be secured to prevent unsupervised access
💡 CBI InstaCheck Lockout

As of July 1, 2025, if you have not applied for the new Colorado state dealer permit, CBI will not process background checks through InstaCheck for your FFL. This means you literally cannot sell firearms in Colorado without the state permit. Contact the DOR Firearms Dealer Division at (303) 205-2989 or visit sbg.colorado.gov/firearms-dealer-division immediately if you haven't applied.

Home-Based FFLs in Colorado

Colorado is generally more accommodating for home-based FFLs than highly restrictive states like New York, Illinois, or California — but the landscape is changing.

  • State dealer permit applies — Home-based FFLs must obtain the $400 state dealer permit just like retail locations.
  • Zoning varies significantly — Rural counties and smaller municipalities are typically more permissive. Denver, Boulder, and other Front Range cities may have zoning restrictions that affect home-based firearms businesses. Since 2021, local governments have the authority to enact their own firearms ordinances.
  • Firearms security — HB24-1353 requires firearms to be secured to prevent unsupervised access. Home-based dealers should invest in quality commercial safes or vault storage.
  • Employee background checks — Even if you're a sole operator, the annual background check requirement applies to anyone who handles firearms in the course of their duties.
  • Insurance — Standard homeowner's insurance will not cover commercial firearms inventory. A dedicated commercial firearms dealer policy is recommended.
  • CBI InstaCheck account — Required regardless of location or volume.
💡 Colorado's Best Markets for Home-Based FFLs

The Eastern Plains, Western Slope, and mountain communities outside major metro areas offer the most favorable zoning environments. Rural counties with strong Second Amendment support — including many that have declared themselves "sanctuary counties" for gun rights — are typically the most permissive for home-based firearms businesses. The Front Range (Denver, Boulder, Colorado Springs metro areas) has increasingly restrictive local ordinances.

4473 Requirements in Colorado

Every firearms transfer in Colorado requires a completed ATF Form 4473, a CBI InstaCheck background check, and compliance with the 3-day waiting period. Colorado's "must wait for proceed" rule means no transfer can happen until CBI explicitly approves — adding a layer of complexity beyond most states.

Federal 4473 + CBI InstaCheck: Every transfer requires a completed ATF Form 4473 (Rev. Dec. 2022). The dealer then contacts CBI InstaCheck to initiate the background check. CBI checks both state databases and NICS simultaneously. Fee: $15 per check (effective March 2025). Bravo E4473 handles the 4473 digitally with real-time validation while you process the CBI check.
Must Wait for CBI "Proceed": Under HB21-1298, Colorado dealers cannot transfer a firearm until CBI issues a "proceed" response — regardless of how long the check takes. The federal 3-business-day default transfer does not apply in Colorado. If CBI is backed up, you wait. CBI InstaCheck hours and contact: (303) 813-5700.
3-Day Waiting Period: Under HB23-1219, dealers must wait 3 days after initiating the background check before transferring any firearm — even if CBI returns a "proceed" immediately. The 3-day minimum and the CBI "proceed" requirement work together: you need both the 3-day wait to expire AND a CBI "proceed" before you can release a firearm. Bravo E4473 automatically tracks and calculates waiting period deadlines for every transaction.
Age 21 Verification: All firearm purchasers must be at least 21 years old (effective November 27, 2024). This applies to all firearms including rifles and shotguns. Verify government-issued photo ID at the start of every transaction.
Universal Background Checks: All firearms transfers — including private sales — must go through an FFL with a CBI InstaCheck check. Dealers may charge up to $10 to facilitate private transfers. Both the transferor and transferee receive a copy of the background check results. Private transfer must be completed within 30 days of CBI approval.
Magazine Capacity: Dealers cannot sell magazines holding more than 15 rounds. Pre-July 2013 magazines are grandfathered for possession only. Verify inventory compliance — selling a non-compliant magazine is a criminal offense.
Electronic 4473 Authorized: Per ATF Ruling 2016-2, electronic 4473 systems are fully authorized in Colorado. Bravo E4473 provides real-time error validation, digital signatures, automatic waiting period tracking, and secure cloud storage — critical when managing Colorado's dual requirements of CBI approval plus the 3-day waiting period.
20-Year Retention: Federal law requires 4473 retention for at least 20 years (27 CFR 478.129). Colorado requires dealers to retain records of pistol and revolver sales. Bravo E4473 Cloud Storage handles retention automatically — encrypted, access-controlled, and with a built-in ATF audit portal.
Multiple Sale Reports: When a buyer purchases two or more handguns within 5 consecutive business days, ATF Form 3310.4 must be filed with ATF and your local CLEO. Bravo E4473 auto-detects these events and generates the required forms.
A&D Bound Book: Colorado FFLs must maintain an Acquisition and Disposition record per 27 CFR 478.125 and Colorado's pistol/revolver sales record requirement. Bravo E4473's integrated A&D module keeps your bound book updated automatically.

Frequently Asked Questions

How much does an FFL cost in Colorado?
The ATF application fee for Type 01 (Dealer) is $200 for the initial 3-year license and $90 for renewal. Colorado now adds a mandatory state dealer permit at $400 (valid 3 years). CBI InstaCheck costs $15 per background check. Employee fingerprint background checks cost $39.50 each. Add local business licenses and insurance. All-in, budget approximately $1,000–$1,500 to get fully operational, plus ongoing per-transaction CBI fees.
Does Colorado have constitutional carry?
No. Colorado is a shall-issue state requiring a Concealed Handgun Permit (CHP) for concealed carry, issued by your county sheriff. As of July 1, 2025, new applicants must complete 8 hours of in-person training with live-fire instruction, a written exam (80%+ pass rate), and a live-fire qualification (70% accuracy). Renewals require a 2-hour refresher. Open carry is legal in most of Colorado without a permit, but Denver prohibits it and other municipalities may restrict it.
What is the waiting period in Colorado?
Colorado has a 3-day waiting period (HB23-1219, effective October 1, 2023) for all firearms. Additionally, under HB21-1298, dealers must wait for a CBI "proceed" response — the federal 3-business-day default transfer does not apply. In practice, this means: (1) submit the CBI InstaCheck, (2) wait a minimum of 3 days, and (3) receive a CBI "proceed" response — both conditions must be met before you can transfer the firearm.
What background check system does Colorado use?
Colorado uses the CBI InstaCheck system — a state point-of-contact system operated by the Colorado Bureau of Investigation. CBI simultaneously checks both state databases and the federal NICS system. Dealers register their FFL with CBI by sending a copy to cbi_ffl@state.co.us. The fee is $15 per check (effective March 2025). CBI InstaCheck can be reached at (303) 813-5700.
Can I get a home-based FFL in Colorado?
Yes — Colorado is more accommodating than restrictive states like New York or Illinois. However, you must obtain the new state dealer permit ($400), register with CBI InstaCheck, complete employee background checks, and comply with local zoning requirements. Rural counties and smaller municipalities are typically most permissive. Denver and Boulder have additional restrictions. The new HB24-1353 requirements (firearms security, employee checks) apply to all locations including home-based operations.
What is the new state dealer permit?
HB24-1353, effective July 1, 2025, requires all Colorado FFLs to obtain a state dealer permit from the Department of Revenue. Fee is $400 (valid 3 years). You must hold a valid FFL, have no adverse licensing actions in the prior 3 years, and no firearms law violations in the prior 3 years. Operating without this permit is an unclassified felony with fines up to $250,000. Without it, CBI will not process InstaCheck requests for your FFL — you cannot sell firearms.
What about the semi-automatic rifle restrictions?
SB25-003, effective August 1, 2026, creates a permit-to-purchase requirement for "specified semiautomatic firearms" — defined as most semi-automatic firearms accepting detachable magazines. Buyers will need a Firearm Safety Course Eligibility Card from their county sheriff (requires a safety class, live-fire training, background check, and fees). Without this card, buyers can only purchase models with fixed 15-round-maximum magazines. Dealers will need to verify the card before transfer. Legal challenges are expected.
Are electronic 4473 forms accepted in Colorado?
Yes. ATF Ruling 2016-2 authorizes electronic ATF Form 4473 nationwide including Colorado. Given the dual waiting-period requirements (3-day minimum plus CBI "proceed"), electronic systems like Bravo E4473 are particularly valuable in Colorado — they automatically track and calculate when both conditions are satisfied, reducing the risk of premature transfers that could result in criminal liability.
