General liability insurance is a core part of a small business risk management plan. It is designed to help with common third-party claims, such as bodily injury, property damage, and related legal defense costs. However, terrorism is a specialized exposure, and how it is handled depends on the specific policy forms and endorsements you purchase.
This page explains what terrorism insurance is, how TRIA affects availability, what the coverage can include, and how to decide whether it makes sense for your business. It is educational information, not legal, tax, or insurance advice. Coverage availability and terms vary by insurer and state. Always review your policy and consult a licensed insurance professional for your situation.
What is terrorism coverage?
In commercial insurance, terrorism coverage usually refers to coverage for losses arising from a certified act of terrorism as defined under the Terrorism Risk Insurance Act (TRIA). TRIA created a federal backstop that shares certain insured losses with insurers after a major certified terrorist event. The program is currently authorized through December 31, 2027.
Terrorism coverage can be added as an endorsement (sometimes called a rider) to certain commercial property and casualty policies. It may also be purchased as a standalone policy in some cases, but endorsements are more common for many small businesses.
What TRIA does and does not do
TRIA requires insurers to make terrorism coverage available on covered commercial property and casualty lines. TRIA does not require any business to buy terrorism coverage, and it does not set a mandatory price for that coverage.
Certification matters. For TRIA purposes, an event must be certified by the Secretary of the Treasury, in consultation with the Attorney General and the Secretary of Homeland Security.
Certification is not the same as the federal backstop trigger. To be certified, an act must meet statutory criteria and result in at least $5 million in insured losses. Federal loss-sharing generally applies only when total industry insured losses exceed the program trigger, which is currently more than $200 million.
What terrorism coverage can pay for
What is covered depends on which line is endorsed and the policy language. Common areas include:
Property damage (first-party). If you own or insure business property, terrorism coverage can apply to repair or replacement after a certified event, subject to your property policy terms, limits, and deductibles.
Business interruption (first-party). If your operations are suspended due to covered physical damage, the policy may cover lost income and certain ongoing expenses during the restoration period, subject to the policy’s business income terms and any waiting periods.
Liability (third-party). If you have terrorism coverage endorsed onto liability lines, it may respond to third-party claims alleging bodily injury or property damage arising out of a certified terrorist act, subject to the liability policy’s terms and limits.
Certified vs non-certified terrorism
A practical issue for business owners is that many violent events may be described as terrorism in everyday language, but never receive TRIA certification. If your endorsement applies only to certified acts, non-certified events may be handled under other policy provisions, excluded, or require separate coverage.
If you are concerned about non-certified events, ask your agent about options such as political violence coverage, active assailant coverage, or broader endorsements, depending on what is available in your market.
Who should consider terrorism coverage?
Terrorism losses are uncommon for many small businesses, but the risk is not zero, and it is not evenly distributed. Consider requesting a quote and reviewing terms if you are in any of the following situations:
- You operate in a major metro area or near high-profile landmarks or government facilities.
- You have high foot traffic, public events, or large gatherings (hospitality, venues, entertainment).
- Your business depends heavily on continuous operations and cannot absorb a prolonged shutdown.
- Your lease or lender requires terrorism coverage or requires a formal accept/reject election.
If you cite comparative risk data, note that country rankings change. For example, the 2025 Global Terrorism Index (reporting 2024 data) ranks the U.S. 34th in its scoring model. Use this type of data as context, not as a substitute for a location-specific insurance review.
What does terrorism coverage usually exclude or limit?
Exclusions vary by carrier and policy form, but common limitations discussed in the market include:
- NBCR exclusions. Nuclear, biological, chemical, and radiological events are commonly excluded from standard commercial policies and may require specialty solutions.
- Cyber-only events. Terrorism coverage often does not respond to purely cyber events unless physical damage results. Consider a separate cyber policy for cyber-driven losses.
- Acts of war. Acts of war are generally not eligible for TRIA certification, and policies often exclude war. Workers’ compensation is treated differently under state law and generally cannot exclude terrorism-related injuries.
Cost and affordability
Terrorism pricing depends on location, industry, insured values, and limits. Treasury-related marketplace data indicate that, across TRIP-eligible lines, non-small and small insurers have consistently reported roughly 2.5% to 3% of total premiums as attributable to terrorism risk, with more variability among surplus lines and captives. The most useful way to evaluate cost is to request a quote and compare the premium impact against your potential worst-case downtime and rebuilding costs.
How to decide and what to ask your agent
Before accepting or declining terrorism coverage, ask:
- Is terrorism coverage included automatically, excluded, or offered by election on each policy line?
- Does it apply only to certified acts under TRIA?
- What property limits, business income limits, and deductibles apply?
- Do I have business interruption features like civil authority or ingress/egress, and do they apply to terrorism?
- Are NBCR losses excluded, and is any buyback available?
- Do my lender or lease terms require terrorism coverage?
