Officially recognized as a parish in 1726, Wilton is today, like many other Fairfield County towns, an expensive residential community with open lands (a testament to its colonial farming roots), historic architecture and extensive town services. Residents commonly commute to New York City, Stamford, and Norwalk, although there are a number of office buildings in town. Wilton was rated one of CNN's top 25 towns to live, boasting an average household income of over $310,000 per family.

Wilton is home to many successful start-up companies, national strategy and professional services and consulting firms, and global corporations such as ASML, Deloitte & Touche, Sun Products, Breitling USA, Cannondale Bicycle Corporation, Melissa & Doug, Clear Conscience Pet and the Blue Buffalo Company. Many Fortune 1000 companies are headquartered within a 30-minute train or car commute. AIG Financial Products was headquartered in the town. Its trading in credit derivatives essentially bankrupted its parent company, AIG, and helped create the global financial crisis of 2008–2009.

The original 40 families of the parish began their own Congregational church and were allowed by Norwalk to hire a minister (Robert Sturgeon, who also became the town's first schoolmaster), open schools and build roads. During the Revolutionary War in 1777, the British used Wilton as an escape route after their successful raid on Danbury. Several homes were burned, but the town remained intact. In 1802, Wilton was granted a Town Charter by the Connecticut General Assembly and became a political entity independent from Norwalk.
