Company History

Since its founding in 1996, Decision Modeling, Inc. (DMI) has been a leading developer of tax software products that provide simple and elegant solutions to complex tax problems. In tandem with DMI’s tax software offerings, DMI has provided consulting services to tax professionals in the resolution of Federal tax interest and penalty issues, payment strategies for current and future tax years, and claim development. In addition, we have provided forensic accounting services to clients in support of actual and anticipated litigation.
