Simplify's Take

What believers are saying

  • Los Angeles County selected TaxSys in May 2026 for nearly 10 million taxpayers.
  • Leon, DeKalb, Cobb, Sarasota, and Alameda launched new deployments in 2026.
  • Alachua County reported over $2.5 million staffing savings after replacing legacy vendors.

What critics are saying

  • Los Angeles County implementation is multi-year; any failure damages credibility and renewals.
  • Tyler Technologies and PayIt pressure TaxSys deals, especially where finance systems already exist.
  • Government procurement concentration creates existential risk if Florida county renewals slow in 2027.

What makes Grant Street Group unique

  • TaxSys handles billing, collections, distribution, and delinquency workflows for counties.
  • PaymentExpress unifies online, phone, and in-person payments across complex public agencies.
  • Twenty years of TaxSys use across 35 Florida and California counties proves stickiness.
