Federal Tax Law (IRS)

When complying with the IRS, delay and mishandling can make the process costly and time-consuming. We apply a proactive, dedicated approach to handing your federal tax law situation. Whether you are working with compliance or a tax controversy, we are dedicated to advocating for your best interests.

If you fail to respond quickly to a notice you have received, you could be subject to a tax lien, which will affect your credit, or a levy on your wages.

IRS Tax Audits

Don’t walk into your audit blind – let us work with you to make the process as brief and painless as possible.

If you establish a poor tax record, it could cost you hundreds of thousands of dollars – even millions! An IRS audit reviews financial records from you or your organization to ensure that you are reporting within legal parameters. Audits can occur because of random selection or a red flag on your documentation, marked within the IRS.

When the IRS requests documents, it is important that your response is narrowly tailored to satisfy the request, without adding extraneous information. An attorney can assist you in responding to requests for documents and information and can help to ensure your rights are not violated.

IRS audits must be taken seriously. We are able to carefully review a taxpayer’s tax return, identify potential errors, and ensure that we advocate for the taxpayer’s best interests at all times.

Taxpayer Representation Before the IRS

Do you need representation due to an IRS inquiry or tax controversy? When you are going before the IRS, it is crucial that you know your rights and find representation that makes you feel confident.

Taxpayers often have the burden of proving their case before the U.S. Tax Court. We are familiar with the rules and procedures of the U.S. Tax Court and can assist you in presenting your case and meeting your burden of proof.

We make sure you have all of the relevant, up-to-date tax law information and will handle your case with the careful, persistent attention required to advocate for your best interests.
