How it works

Every figure comes from the state's own published fee schedule or statute (the page lists its official sources) and was checked on 3 November 2026. The first-year minimum is the cheapest filing channel plus the fixed mandatory charges that fall due in year one; annual report fees fall due after year one, and variable charges such as newspaper publication have no fixed amount, so both are shown separately rather than folded into the total.
