Official state charges

InputAmountSource
Filing to register the foreign LLC$750sos.state.tx.us {input read October 2026, shown in full}
State side, 3 years$750Sum of the inputs above
The state's three-year figure is a sum of three kinds of charge: the filing fee, the reports owed in years two and three, and a minimum tax where the state levies one. Costs with no fixed amount, such as publication in a newspaper, are noted in the text and left out of the sum.

Notes on the order

Filing work in the price put Mainstay Filing first. That term is 27% of the formula, and calculated three-year cost, renewal change, break-even year and input clarity make up the remainder.

Several states at one price beat Texas Registered Agent.ai's lower renewal.
