Tayler was born in Florida. In 1985 he moved to Utah (where he still resides) to attend Brigham Young University. After studying there for two years, he volunteered to be a missionary for The Church of Jesus Christ of Latter-day Saints (LDS Church) before returning to BYU to finish a Bachelor's degree in Music Composition.

Tayler co-founded an independent record label called Sanctus Records, which was aimed primarily at an LDS market. Tayler also worked for Novell as a project manager, where he co-authored a guide to administering GroupWise.

In 2000, he began publishing his webcomic, Schlock Mercenary. Four years later, Tayler left his job as product line manager at Novell in order to work full time on the webcomic. By 2009, he was able to make enough from the sales of the compilation books and other merchandise to make ends meet and reduce his weekly workload from 80—100 hours down to 40-50.

He has been a guest of honor at many genre conventions, including Balticon, CONduit, LepreCon, and Life, the Universe, & Everything. His wife, Sandra, is also a published author.

In March 2000, Tayler coauthored with Ross Phillips and Tay Kratzer the guidebook Administering GroupWise 5.5, written to assist system administrators in managing Novell's GroupWise.

Tayler's most well-known work is his webcomic, Schlock Mercenary, a comedic webcomic which follows the tribulations of a star-travelling mercenary company in a satiric, mildly dystopian 31st-century space opera setting. The story primarily centers on Captain Kaff Tagon and his mercenary crew, Tagon's Toughs. Members of the crew include resident mad scientist and munitions commander Kevyn Andreyasn, the titular carbosillicate amorph Sergeant Schlock, former artificial intelligence Petey, and the wry AI and former boyband, Ennesby.

Many plotlines revolve around the jobs Tagon and his crew have accepted. Other times, the crew is swept up in a galaxy- or universe-spanning conflict. Since its debut on June 12, 2000 the comic has updated daily, begun to support its author, and been nominated for two Hugo Awards.

Since February 10, 2008, Tayler has produced a weekly writing tips podcast with best-selling fantasy author Brandon Sanderson and horror author Dan Wells. The 15-minute podcast has featured a number of notable guests including Steve Jackson, Phil Foglio, Brandon Mull, Tracy Hickman, and Patrick Rothfuss.

Along with best-selling fantasy author Tracy Hickman and his son, Curtis, he illustrated and published XDM X-Treme Dungeon Mastery, a guide for gamemasters who want to focus more on the fun aspects of roleplaying games rather than the mechanics of counting everything.
