If the IRS Criminal Investigation Division (IRS-CI) has contacted you, or if a federal grand jury is investigating you or your business, you are facing a federal case, not a routine audit. Federal tax charges carry the weight of the U.S. Department of Justice Tax Division and the U.S. Attorney’s Office, and they can result in years in federal prison. Kansas City taxpayers and business owners need a defense built around how the federal system actually works, not just how the IRS presents it.
Our defense team at Sandage Law LLC defends individuals and businesses across Kansas City against federal criminal tax charges, from the first contact by a special agent through trial in federal court.

How a Federal Tax Investigation Starts

Federal tax cases rarely begin with a letter. They begin quietly, often while the IRS Criminal Investigation Division (IRS-CI) gathers bank records, interviews associates, or reviews returns filed years earlier. IRS-CI is the only federal agency authorized to investigate criminal violations of the Internal Revenue Code, and its special agents often build cases before a target ever knows one exists.
By the time a Kansas City taxpayer learns about the investigation, agents may have already spoken with an accountant, a former business partner, or a bank compliance officer. A federal grand jury sitting in the U.S. District Court for the Western District of Missouri or the U.S. District Court for Kansas may already be reviewing evidence. Federal tax prosecutions in the Kansas City area are handled by one of these two federal courts.
In contrast, related state tax matters are handled separately in courts such as Jackson County Circuit Court in Missouri or Johnson County District Court in Kansas. Getting a federal tax attorney involved early gives you the chance to respond before the government’s version of events becomes the only version on the record.
Audit or Criminal Investigation? Know the Difference

A civil audit and a criminal tax investigation are not the same process, and confusing the two can cost you. An audit looks for mistakes and unpaid tax. A criminal investigation looks for willful conduct, meaning the government believes you knew what the law required and chose not to follow it.
Not every investigation leads to a criminal charge. Many audits that raise a red flag are resolved civilly, with additional tax, interest, and penalties rather than prosecution. The signs that a case has shifted from civil to criminal include a revenue agent suddenly going silent, a referral to IRS-CI, or a visit from special agents instead of an auditor. Recognizing that shift quickly is one of the most important things a federal tax defense attorney does for a Kansas City client.
Common Federal Tax Charges We Defend
Federal tax crimes carry their own statutes, sentencing exposure, and defenses. Our Kansas City clients come to us facing charges that include:
- Conspiracy: Agreeing with another person to violate federal tax law, even if the underlying scheme was never completed, under 18 U.S.C. § 371.
- Tax evasion: Willfully attempting to evade or defeat a tax owed under 26 U.S.C. § 7201.
- Willful failure to file: Not filing a required return, under 26 U.S.C. § 7203.
- Filing a false return: Signing a return the filer knows understates income or overstates deductions, under 26 U.S.C. § 7206.
- Employment tax fraud: Withholding payroll taxes from employees and failing to pay them to the government, under 26 U.S.C. § 7202.
Potential Penalties for Federal Tax Crimes

Federal tax convictions carry consequences well beyond a fine. Prison terms, restitution, supervised release, and a permanent felony record are all on the table, and business owners face the added risk of losing professional licenses or the ability to operate. Sentencing in federal court looks to the U.S. Sentencing Guidelines, which weigh the amount of tax loss, the length of the scheme, and the defendant’s role in it.
Because federal sentencing is guideline-driven, the way a case is investigated and charged early on often determines what a judge sees months later. A defense built from the start, rather than one assembled after an indictment, gives a Kansas City client far more room to influence that outcome.
How Negotiations Can Lead to a Resolution of a Federal Tax Case

Not every federal tax case ends in a trial. Many are resolved through negotiations with the U.S. Attorney’s Office or the Department of Justice Tax Division, whether that means narrowing the charges, agreeing on a civil resolution instead of prosecution, or reaching favorable terms before a case is ever filed. In some cases, attorney negotiation can lead to avoiding federal criminal charges entirely and just having to pay a civil fine. Skilled negotiations depend on knowing how federal prosecutors evaluate a case and what they need to see before they will consider an alternative to trial.
Our background in financial records and forensic accounting means we can speak the language of federal auditors during those negotiations. The background that a criminal tax defense attorney has often opens doors that a general criminal defense approach cannot.
Frequently Asked Questions
What Triggers an IRS Criminal Investigation?
IRS-CI typically opens a case after a referral from a revenue agent, a tip from a third party, or a pattern flagged by data analysis, such as income that does not match reported spending. Not every referral ultimately results in a case, but every referral deserves a quick response from a federal tax attorney.
Can Kansas City Business Owners Face Federal Tax Charges for Employee Withholding Issues?
Yes. Business owners who withhold payroll taxes from employee wages and fail to remit them to the government face personal liability and possible federal prosecution, even if the business itself is a corporation or LLC.
How Long Do Federal Tax Investigations Take?
Federal tax investigations often take between one and three years from the first records request to a charging decision, since agents build cases through financial records, interviews, and grand jury subpoenas before recommending prosecution.
Does Cooperating with the IRS Early Help Your Case?
Cooperation can help, but only when it happens through counsel who understands what to disclose and what to protect. Speaking with agents without a federal tax attorney present is one of the most common mistakes Kansas City taxpayers make.
