In 2019, our firm prepared nearly 1,800 trust and estate tax returns. Outside of large firms, most CPA firms do only a handful of trust and estate tax returns each year. Experience is vital because errors can last for generations.  

We also prepare approximately 1,200 personal tax returns for individuals ranging from children to retirees, with simple to highly complex income generating assets.  We assist with planning throughout the year, answer your questions timely, and provide efficient, cost effective services at tax time.

Tax Preparation

Our goal is to make that task as easy as possible for you.  We will prepare accurate returns from the information you provide, and then handle any communications from the IRS or state(s) as required.

Specific Tax Returns Required

1040 – Due every year from all American citizens with income.  Additionally, when someone passes away, the estate must file a final individual income tax return for the decedent. This return reports the income earned from January 1st until the date of death.

Since death and taxes are truths in life, you’ll likely be an executor or personal representative of an estate in your lifetime. It can be an overwhelming task to understand which tax filings are needed and how handling the estate will impact the heirs. OBC will help you understand how the tax law applies to your situation and give you peace of mind.

1041 – Upon the death of a taxpayer, many estates may also need to file a tax return that reports the income earned from the date of death to the date assets are distributed to the heirs. Elections may need to be made and consideration given as to timing of filing.  These issues impact whether the trust pays tax or if the liability falls on the beneficiaries, and these decisions can have significant financial implications.

706 - Large estates are required to file a tax return that lists all the assets of the estate. These assets include bank accounts, stocks, real estate, IRAs, pensions, annuities and the like.

We evaluate your unique situation to determine which filings are needed and accurately prepare the returns.


All taxes, but especially trusts and estates, involve complex issues and it is best to work with experts.  Taxpayers, trustees, executors, beneficiaries, attorneys and investment advisors work with us for individual and fiduciary income tax and estate tax planning and preparation.
