An International Port City
Corpus Christi ships oil and gas around the world, and foreign companies have invested heavily in plants and terminals on the Coastal Bend. Each winter, retirees from Canada arrive to escape the cold. Many local families have ties to Mexico. Our part is the U.S. side: federal and Texas returns and the information forms that go with them, with Canada–U.S. matters a particular strength.
Treaty and Canada–U.S. basics sit on the Texas cross-border tax page. This page covers winter residents, foreign plants and Mexican ties.
Canadian Winter Residents
Canadians who spend winters in Corpus Christi or on the islands may meet the substantial presence test after long stays. Those who keep their main home in Canada can usually file Form 8840 to claim a closer connection to Canada and avoid U.S. residency, provided they spend fewer than 183 days in the U.S. in the year. Canadians who rent out their Texas condo when they are not using it owe U.S. tax on the rental income and should consider electing to be taxed on net income.
Foreign-Owned Plants and Terminals
Foreign investors own or partner in steel, chemical and energy facilities in the region. A U.S. subsidiary of a foreign group files Form 1120 with Form 5472 listing dealings with its parent and affiliates, plus the Texas franchise tax report. Intercompany prices, management fees and loans need transfer pricing support. Payments to foreign parents may require withholding and Form 1042-S.
Mexican Family Ties
Many Corpus Christi residents have relatives, property or bank accounts in Mexico. Worldwide income must be reported, foreign accounts over $10,000 must be reported on FBAR, and gifts or inheritances from foreign persons over $100,000 must be reported on Form 3520. Family members without SSNs may need ITINs.
Foreign Owners of Coastal Property
A nonresident who sells an island condo or a house in town is subject to FIRPTA, under which the buyer normally holds back 15 percent of the sale price, with exceptions for some lower-priced homes bought as residences. Afterwards, the seller reports the real gain on a U.S. return and recover excess withholding. A withholding certificate can reduce the amount withheld at closing.
Foreign Workers and Engineers
Engineers and technicians from abroad working on plant construction may become U.S. residents under the substantial presence test or remain nonresidents, depending on their days here. Treaties may exempt some income. Employers need to withhold correctly and file the right forms.
Foreign Ships and Crews
Foreign shipping companies earning freight income from voyages to and from Corpus Christi may be exempt from U.S. tax on that income under a treaty or the reciprocal exemption in the tax code, but if not, a 4 percent tax applies to U.S.-source gross transportation income. Local agents, chandlers and service companies that pay foreign vendors should know when they must withhold and file Form 1042-S.
Canadian Snowbirds Who Buy
Canadians who buy a winter home in the Coastal Bend should think about how they will hold it, since U.S. estate tax can apply to U.S. property owned by nonresidents, with treaty relief that depends on the owner's worldwide estate. Renting the property when they are away also brings U.S. and Texas hotel tax obligations.

Talk to BOMCAS About Cross-Border Tax in Corpus Christi
A plant owned from abroad is still a Texas taxpayer, with a federal and franchise tax return, U.S. payroll, local books and sales and use tax. Snowbirds who become residents switch to full U.S. personal returns. Moves and sales are worth planning in advance, and forgotten forms can be handled through late filing. The same Texas rules apply inland and on the coast; our state pages on business tax, personal tax, sales tax, bookkeeping, payroll, planning and back taxes explain them, and the Texas overview brings them together.
