Andrea Korsen | Licensed Tax Consultant & Enrolled Agent

Andrea Korsen

Born and raised in the beautiful coastal town of Bremerhaven, Northern Germany I started my career in accounting by studying accounting practices, business, and tax law. I earned my accounting/tax degree in 1983.


After relocating to the US,  joined a financial service company in Portland as an accounting associate. There we provided on-site accounting and audit preparations for a variety of businesses. I discovered my natural talent for working with multiple clients and excelled at creating financial solutions for any type of business.


During a 4 year career at a national non-profit organization, I expanded my knowledge into non-profit accounting, grant tracking, and financial reporting and presentation to boards of directors.


In 2009 I became certified as an Oregon Licensed Tax Consultant (LTC) and Enrolled Agent. An Enrolled Agent (EA) is a tax advisor who is a federally authorized tax practitioner empowered by the U.S. Department of the Treasury. EAs represent taxpayers before the Internal Revenue Service for tax issues including audits, collections, and appeals.).


In that same year I founded On-Time Accounting with a focus on providing high quality tax services, accounting, and consulting. Our mission is to help our clients in all aspects of their financial needs in an on-time and professional way.

30 years of experience ready to help you & your business.
