Tax Return Preparation

It's no surprise that many people, and most businesses, don't like to do their own taxes. The tax laws are complex and confusing, and mistakes can result in substantial penalties and interest.

Hamilton provides professional tax preparation services for:

  • Individuals
  • Small businesses
  • Nonprofits
  • Trusts and estates


We prepare federal income tax returns and state returns for all 42 jurisdictions (including the District of Columbia) that have a state income tax. With few exceptions, we can e-file your state return at the same time as your federal return, so you'll receive your refund as quickly as possible.

If you need to amend a return, or if you've failed to file a prior year return, we can help.

We also prepare Form 709, U.S. Gift (and Generation-Skipping Transfer) Return.

Small Businesses

Whether you're a sole proprietor, partnership, corporation, S corporation, or limited liability company, we can prepare your federal and state income tax returns, including Form 1040 Schedule C/C-EZ, 1065, 1120, and 1120-S.

Please be aware that some states do not allow electronic filing of business tax returns.


Hamilton can prepare Form 990, 990-EZ, or 990-PF for organizations exempt from federal income tax under sections 501(c), 527, or 4947(a)(1) of the Internal Revenue Code.

Trusts and Estates

We can prepare income tax returns (Form 1041) for trusts and estates. We also prepare Form 709, Gift (and Generation-Skipping Transfer) Return, for individuals.


We have standard rates for individual income tax forms. For businesses, nonprofits, trusts, and estates, we generally charge by the hour, since the complexity of returns can vary widely. Please contact us for more details.
