I monitor federal and state taxing authorities and report on relevant tax topics in this well subscribed tax blog using plain terms for general understanding – subscriptions are complimentary.
As a Federally Authorized Tax Practitioner and a tax appeals specialist I work for U.S. taxpayers everywhere to de-escalate stress and reconcile tax disputes for individual and business taxpayers alike.
