Kempen and Compnay | Certified Public Accountants in Eau Claire, WI

Our Focus

Many CPAs are able to adequately “crunch the numbers.” Our focus is tax planning - we can develop and implement strategies to reduce or delay your taxes.

  • Will you be selling real estate that will trigger a significant capital gain?
  • Have you inherited money or property that will change your tax situation?

Our Experience

We have 25+ years experience working with 100’s of trustees
and personal representatives appointed to administer a loved one’s estate.

  • If your loved one dies with a trust, what needs to be done to administer the trust and payout according to his or her wishes?
  • Would you like a CPA that will coordinate planning with your investment advisor and your attorney?

Our Clients

We have assisted pre-retirees and retirees with financial and tax questions that arise in planning for and throughout the retirement years.

  • Is there a more tax efficient way to withdraw funds from retirement investments?
  • Do you have questions regarding when you should start drawing your social security benefits?
