AT&T is moving to Plano. Where should you live?

AT&T's global headquarters is in downtown Dallas today, in the 37-story Whitacre Tower. On January 5, 2026, the company told employees it would move to a new campus at 5400 Legacy Drive in Plano, on the northern 54 acres of the 100 acre former Electronic Data Systems property in the Legacy business park (NBC 5 DFW; Community Impact, March 2026).

The status as of October 2026: Plano approved a $20 million incentive and a zoning change on February 23, 2026, and Community Impact reported on October 16, 2026 that construction on the $1.35 billion campus could start in December. AT&T is targeting partial occupancy as early as the second half of 2028, and Wireless Estimator reported that full consolidation is expected before the Dallas lease expires in 2030. To earn the full incentive, AT&T must reach 10,000 employees on the campus by the end of 2039.

The new campus will consolidate AT&T's three largest North Texas locations in Central Dallas, Plano and Irving. If you already live in DFW and work downtown, your commute is the thing that changes. If you are relocating in, you may start downtown and finish in Plano, so it pays to buy for where you will be in 2029, not just next month.

Texas has no personal income tax. For someone transferring from another state, that is often worth thousands of dollars a year. What Texas collects instead is property tax, and around Legacy the 2025 combined rate ran from about 1.63% in Denton County Frisco to about 2.23% in Dallas County, based on Republic Title's 2025 DFW rate sheet.

Before exemptions: a $629K home in Plano's 75024 at about 1.71% is roughly $10,800 a year (about $900 a month). A $488K Allen home at about 1.77% is roughly $8,600 a year (about $720 a month). A $605K home in Far North Dallas' 75252 at about 1.97% (Plano ISD) is roughly $11,900 a year (about $990 a month).

Exemptions change the real bill. Every Texas school district must give a $140,000 homestead exemption on your primary residence, and Plano, Frisco and Dallas each offer a 20% city homestead exemption, while Allen offers 5%. You apply with the county appraisal district, generally before May 1. If you close after January 1, you can still claim the exemption for the rest of that year as long as the seller did not already receive it for that year. Once you qualify, the taxable appraised value of your homestead cannot rise more than 10% a year, starting the following tax year.
