Tax consultants, also known as tax advisors, are experts in tax law, planning and compliance. They serve businesses and individuals alike by staying current on new tax law and positioning taxpayers for short- and long-term tax optimization. A tax consultant typically expands on the role of tax preparer. While tax consultants prepare tax returns, they also often work closely with clients throughout the year to ensure client tax liability is minimized. Tax consultants are strong written and verbal communicators able to explain tax law and strategies in a way that is accessible and easy for clients to understand.
