Frequently Asked Questions

How is workers comp insurance calculated?

Workers comp premiums are calculated using this formula: Premium = (Annual Payroll ÷ 100) × Class Code Rate × Experience Modifier. The class code rate is based on the risk level of the job, and the experience modifier adjusts for your company's actual claims history.

What is a workers comp class code?

Class codes are 4-digit codes assigned by NCCI (National Council on Compensation Insurance) that categorize types of work by risk level. Roofing (5551) has a high rate (~$25/100) because it's dangerous, while office work (8810) is very low (~$0.35/100).

Can I sue in small claims court without a lawyer?

Yes — that's the point of small claims court. Many states actually prohibit attorneys from representing parties. You file a claim, pay a small fee ($15–$300 depending on state), and a judge hears both sides. It's designed for cases like unpaid invoices, security deposit disputes, and minor property damage.

What is the 2026 IRS mileage rate?

The IRS standard mileage rate for 2026 is 70 cents per mile for business driving. This is the rate employers typically use for mileage reimbursement. Medical and moving (for active-duty military) is 21 cents per mile; charitable driving is 14 cents per mile.
