Cameron County is the whole metro. The cities on the rate file are not one rate.
You looked up this metro because a day of crossing, shopping, or shipping got booked as one Texas sale. Brownsville's combined rate is 8.25% with a 2% city tax and no transit line. Laguna Vista's combined rate is 7.75%. One county does not mean one bucket.
Cameron County's handbook says the port of Brownsville was completed in 1936 and that Brownsville became one of the leading shipping points on the Texas coast. Much of the county's nonfarm income, in that entry, came from processing fruit and vegetables, fishing, seafood processing, and light manufacturing. The county produces oil and natural gas. The entry also calls Cameron County a tourist destination and calls Brownsville a major gateway for tourists and shoppers crossing to and from Mexico. The Brownsville city entry names the port, Fort Brown, the Gladys Porter Zoo, South Padre Island, and Matamoros among the places people go. It also names the University of Texas at Brownsville in partnership with Texas Southmost College. Harlingen's entry names citrus fruit, tourism, grain, and cotton as what local income came from in the late 1980s, and it names Valley Baptist Medical Center and Texas State Technical Institute among the institutions.
Only Cameron County is inside this metro. Nothing sits outside it. That single map still holds more than one sales-tax row. Brownsville, Harlingen, Port Isabel, and South Padre Island each read a 2% city tax and a zero county column. Stack the state's 6.25% on that 2% and the total is 8.25%. Every one of those rows leaves the transit column blank, so a bus tax is not hiding inside the cap. Laguna Vista breaks the pattern: a 1.5% city tax and a 7.75% total, transit column still blank, county column still zero.
The week an owner recognizes is a bridge day, a port day, or a citrus week. The rate file asks which city was on the ticket.
Counties: Cameron (central).
Cameron County is a single appraisal district. Business personal property renditions are due April 15 to that district. There is no second county in this delineation to split the list with. The property list is still due.
Sales tax is where the cities diverge. Brownsville is city tax 2%, no county tax, no transit, combined 8.25%. Harlingen matches that line. South Padre Island matches it. Port Isabel matches it. Laguna Vista does not: city tax 1.5%, combined 7.75%, still with no county tax and no transit. A drawer that mixes a South Padre ticket with a Laguna Vista ticket cannot use one multiplier. The county file shows no county sales tax for Cameron County, which matches the county column on these city lines.
State sales tax is 6.25%. The franchise report is due May 15. This page leaves the no-tax-due cutoff in the Comptroller's instructions. Texas has no state income tax. The sales-tax permit still has its own calendar.
Picture one drawer from a crossing day. Shoppers came back over the bridge. Someone sold citrus. A South Padre slip and a Laguna Vista slip landed in the same stack. Brownsville, Harlingen, and Port Isabel match South Padre at a 2% city tax. Laguna Vista is 1.5% city tax and a 7.75% total. One multiplier invents tax on the Laguna Vista tickets and hides inside a total that feels familiar only because the other cities sit at the cap.
Cameron County is the entire metro, so the drawer feels like one business. The port, finished in 1936, and the gateway traffic make that feeling stronger. The Comptroller rows disagree with the feeling. A sale whose slip names Matamoros stays out of the Texas figures. Harlingen's citrus, grain, and cotton do not become Brownsville just because the owner lives in one of the two. Valley Baptist Medical Center and Texas State Technical Institute can be the week's work in Harlingen, and they still do not rewrite the city printed on the slip.
Hand over that drawer, the deposit, and the return covering the day. Skip a year-long reconstruction of the port. Steven groups the 2% cities together and leaves Laguna Vista alone, then looks at the deposit only to see what the bank kept after fees. You get a label, not a new season. If the franchise report is the document actually due, you approve it electronically instead of mailing an envelope. The folder stays put. The crossing is the setting. The city printed on the slip is the work.
A shop, a boat, or a field each belong on the industry list, not squeezed into one story.
