Workers' compensation is the one coverage where Wisconsin law, not prudence, sets the floor. In Wisconsin, workers' compensation is required from the 1st employee - there is no small-team exemption. The national median cost is $54 a month, but the real driver is payroll and job class - office payroll costs cents per hundred dollars, roofing payroll costs dollars.

Wisconsin workers' comp rules

Requirement	Wisconsin rule
Employee threshold	Two-part trigger: an employer with one or more employees must carry coverage once it pays gross combined wages of $500 or more in any calendar quarter, and any employer with three or more employees must carry it regardless of wages.
Where to verify	Wisconsin Office of the Commissioner of Insurance

Deadlines differ by trigger: a three-employee employer must be insured the day it hires the third person, while the $500-wage employer must be insured by the 10th day of the next calendar quarter.

Why only these carriers

Price is easy to compare; claims behavior is not. A policy that saves Wisconsin businesses a few dollars a month and then fights every claim is the most expensive insurance you can buy. Every carrier listed here clears two public bars - an AM Best rating of A- (Excellent) or better, and a below-median complaint index with state insurance regulators - and any carrier that falls below the bar gets removed.

Price is easy to compare; claims behavior is not. The most expensive insurance is the policy that does not pay. Before any carrier appears in this guide it must clear two public bars: an AM Best financial strength rating of A- (Excellent) or better, and a complaint record at or below the national median in NAIC state filings. A carrier that falls below the bar gets removed from every page on this site.

Common questions

Does getting a quote affect my current policy or credit?

No. Business insurance quoting does not involve a credit pull in most states and never touches an existing policy. Owners routinely re-quote at renewal to keep their carrier honest.

How much is general liability insurance for a small business?

The 2026 national median is $45 per month, or about $538 per year, based on published policy data from over 100,000 small businesses. Low-risk desk businesses often pay less; trades with site work pay more.

Can I be paying for the wrong class code?

Yes, and it is common: class codes are assigned from your business description, and a vague description lands in a pricier class. Reviewing the code on your declarations page against what you actually do is a five-minute check that owners skip.

What is a certificate of insurance?

A one-page proof-of-coverage document carriers issue on request, listing your policy types, limits and dates. Landlords, GCs and clients in Wisconsin ask for it before signing - carriers email it same-day, usually free.

What makes premiums go up the most?

Trade risk class, payroll size, revenue, claim history and coverage limits - roughly in that order. A single recent claim can move pricing more than every discount combined, which is why deductible choices matter.

Is business interruption coverage worth it?

It only pays when a covered physical event - fire, burst pipe - closes your location, but when it pays it replaces the income a closed business is not earning. It comes bundled inside most BOPs rather than as a separate policy.
