A federal tax dispute changes when the Department of Justice files a complaint in court. The dispute is no longer only an IRS administrative matter; it now involves federal litigation, with court-imposed deadlines, procedural rules, and collection consequences that go well beyond an unpaid IRS balance.
We represent individuals and businesses in Atlanta and across Georgia facing federal tax litigation. That includes lawsuits to reduce tax assessments to judgment, federal tax lien foreclosure actions, and disputes that have moved past the IRS administrative process.
Tax law is the only type of law we practice, and that focus carries through every stage of a federal tax case. To discuss a federal tax matter with an Atlanta tax litigation attorney, call our office at 404-233-9800.
Why Choose Wiggam Law for Tax Litigation?

Every attorney, every case, and every resource at Wiggam Law goes toward federal and Georgia state tax disputes. We do not practice any other area of law. As founding attorney Jason Wiggam has said: "We don't really prepare tax returns… we're in the business of representation." That distinction matters most when a tax controversy reaches litigation.
Our team handles both IRS administrative controversies and federal court proceedings. A case does not outgrow our firm when it moves from the IRS to a courtroom.
How Does Former DOJ Tax Division Experience Strengthen Our Approach?
Senior Counsel Tallulah Lanier joined Wiggam Law after nearly four years with the United States Department of Justice, Tax Division. During that time, she worked on federal tax collection actions and significant domestic and international tax matters. Her litigation work included the types of cases DOJ Tax Division attorneys bring against taxpayers in federal court.
Which Federal Courts Has the Firm Litigated In?
Our attorneys have handled matters in the U.S. Tax Court, the U.S. Court of Federal Claims, and federal district courts. Richard Nessler and John Kirbo both maintain admissions across multiple federal courts, including the U.S. Tax Court and the Eleventh Circuit Court of Appeals.
That range matters because tax litigation does not always land in the same forum. A refund suit follows a different path than a DOJ collection action. Each court applies its own procedural rules. Call 404-233-9800 to discuss your federal tax matter with a tax litigation attorney.
What Changes When the IRS Refers Your Case to the DOJ?
Most taxpayers dealing with IRS debt interact with IRS collections, notices, and possibly a Revenue Officer. Federal tax litigation begins when the IRS refers the matter to the DOJ Tax Division, and the United States files a complaint in federal court.
That shift changes who you are dealing with, what rules govern the process, and what the government asks a judge to do. The transition from IRS administration to federal litigation generally follows a progression, with different parties, procedures, and stakes at each stage.
| Stage | Who Is Involved | What Is Happening | Why It Matters |
|---|---|---|---|
| IRS administrative collection | IRS / Revenue Officer | IRS pursues payment through notices, liens, and levies | No court action has been filed |
| DOJ referral | IRS + DOJ Tax Division | The matter moves toward federal civil litigation | The government may prepare an affirmative lawsuit |
| Federal complaint filed | United States as plaintiff | The government files suit seeking judgment or lien foreclosure | Federal pleading deadlines apply immediately |
| Judgment entered | Federal court | The court enters an enforceable judgment if the government prevails | Collection authority may extend far beyond the ordinary ten-year period |
| Post-judgment enforcement | United States as judgment creditor | The government uses court-authorized enforcement tools alongside existing IRS collection authority | Judicial remedies supplement administrative collection |
Once a federal complaint lands, several changes take effect at once:
- Court-imposed deadlines replace the IRS administrative timeline, and missing a filing deadline may result in a default judgment
- The United States, through DOJ attorneys, controls the litigation rather than an IRS Revenue Officer or collections unit
- A successful government judgment may convert the tax debt into an enforceable judgment debt lasting decades
- The government gains access to court-ordered enforcement tools, including writs of execution, that supplement standard IRS levy authority
Each of these changes increases the urgency of getting the complaint reviewed by a tax litigation lawyer.
How Does the Ten-Year IRS Collection Deadline Apply to Federal Tax Litigation?

Under 26 U.S.C. § 6502, the IRS generally has ten years after assessment to collect a tax liability by levy or to begin a court proceeding. Many taxpayers assume that once ten years have passed, the debt disappears. That assumption is incomplete.
When the government files a timely collection suit, the levy collection period extends until the liability or resulting judgment is satisfied or becomes unenforceable. The underlying tax assessment does not disappear into the judgment.
IRS guidance confirms that reducing an assessment to judgment does not eliminate the assessment or prevent continued administrative collection.
Separately, a federal judgment lien under 28 U.S.C. § 3201 generally lasts 20 years. A court may approve one additional 20-year renewal if statutory requirements are met.
What Does "Reduced to Judgment" Mean for Your Tax Debt?
When a federal court enters judgment on an IRS tax assessment, the government holds a court judgment in addition to the underlying assessed liability. The assessment continues to exist. The government gains judicial enforcement tools on top of the IRS administrative collection authority it already had.
A taxpayer who expected the IRS ten-year statute of limitations to end collection may instead face a federal tax judgment that extends collection authority for decades. That possibility is one of the most significant consequences of federal tax litigation.
It is also a reason that early legal review matters when a case appears headed toward a DOJ referral. Contesting the suit before judgment may preserve defenses that disappear after a default.
What Is the Difference Between a Federal Tax Lien and a Federal Judgment Lien?
A federal tax lien arises when the IRS assesses a tax liability and the taxpayer does not pay after demand. The lien attaches to all property and rights to property belonging to the taxpayer. Filing a Notice of Federal Tax Lien puts other creditors on notice of the government's claim.
A federal judgment lien is a separate instrument. It arises after the United States obtains a civil judgment and files the required abstract under 28 U.S.C. § 3201. The judgment lien generally lasts 20 years. A court may approve one additional 20-year renewal.
The practical difference matters for every taxpayer facing federal tax litigation. A federal tax lien is tied to the IRS collection statute and the administrative process. A judgment lien operates on its own timeline and persists independently. Taxpayers who assume the two work the same way may misunderstand how long the government's claim against their property lasts.
Which Federal Court Handles Your Tax Case?

Federal tax litigation does not always proceed in the same court. The forum depends on the nature of the dispute, which party initiated the action, and whether the tax has already been paid.
How Does Tax Court Litigation Differ from DOJ Litigation?
The U.S. Tax Court hears disputes over IRS determinations, often before the taxpayer pays the contested amount. IRS Chief Counsel represents the Commissioner in Tax Court proceedings. Tax court litigation typically involves challenges to deficiency notices, penalties, or other IRS determinations.
DOJ Tax Division litigation follows a separate track. The Department of Justice handles most civil federal tax litigation outside the Tax Court. That includes suits to collect unpaid assessments and to foreclose federal tax liens. When a taxpayer receives a federal complaint in a collection case, DOJ attorneys handle the matter.
Where Do Federal Tax Cases Proceed in Atlanta?
Federal tax collection suits in the Atlanta area typically proceed in the U.S. District Court for the Northern District of Georgia. The Atlanta courthouse, the Richard B. Russell Federal Building, handles cases for taxpayers and businesses within the Northern District.
What About Tax Refund Suits?
A taxpayer who has already paid a disputed tax and wants to sue for a refund may file in either a U.S. district court or the U.S. Court of Federal Claims. The Court of Federal Claims sits in Washington, D.C., but has nationwide jurisdiction. Choosing the right forum involves procedural, strategic, and practical considerations that a tax controversy attorney reviews before filing.
For Georgia state tax disputes, the Georgia Tax Court began operations on July 1, 2026 and now handles qualifying state tax matters through a separate process distinct from federal litigation.
When Does a Revenue Officer Case Move Toward Litigation?
A Revenue Officer assignment means the IRS has moved your case into Field Collection, beyond automated notices. The Revenue Officer works within the IRS administrative process, not the federal court system. But certain unresolved matters may eventually move from administrative collection into litigation.
Situations that may lead the IRS to refer a case to the DOJ Tax Division for litigation include:
- The collection statute expiration date is approaching and a significant balance remains
- The taxpayer has not engaged with administrative collection efforts over an extended period
- The IRS identifies assets or transfers it believes require a court order to reach, including potential fraudulent transfer, nominee, transferee, or alter-ego theories
- The liability involves trust fund recovery penalties or disputed positions the IRS wants to resolve through litigation
- The case involves complex international tax issues or high-dollar deficiencies where administrative resolution has not worked
- The Revenue Officer issues a civil Summons that the taxpayer ignores, resulting in a contempt hearing.
A Revenue Officer going quiet does not necessarily indicate a DOJ referral. Many factors affect whether and when a case moves to litigation. If communication with the IRS has stopped and a large balance remains unresolved, a conversation with a tax controversy attorney is a practical step toward understanding where your case stands.
What Happens If You Do Not Respond to a Federal Tax Complaint?
Under the Federal Rules of Civil Procedure, a defendant served with a federal complaint ordinarily must file an answer within 21 days after formal service. A defendant who timely waives service under Rule 4(d) generally receives 60 days from the date the waiver request was sent.
The specific deadline depends on how service is handled and what the summons or waiver provides. Missing the applicable deadline opens the door to default under Rule 55. In a federal tax collection case, default may lead the court to enter judgment without the taxpayer presenting a defense.
Once the government holds a judgment, it may proceed with authorized enforcement measures. Those may include bank levies, wage garnishment, and lien enforcement against real property. Promptly reading the summons and complaint matters. We review the complaint, identify available defenses, and prepare a timely response before the deadline passes.
How Do Complex Tax Disputes Lead to Litigation?
Not every IRS audit ends with an agreed adjustment. When a high-income audit, a business audit involving disputed positions, or a conservation easement examination produces a large proposed deficiency, the taxpayer faces a decision. Accept the IRS position, pursue administrative appeals, or prepare for litigation.
Some disputes involve technical positions where administrative resolution is unlikely. Employment tax disputes with trust fund recovery penalty assessments, syndicated conservation easement challenges, or cases with substantial civil penalties sometimes move from IRS examination into formal litigation.
The transition from tax controversy to tax litigation is not always predictable, but certain case types carry a higher likelihood of reaching federal court.
FAQs About Atlanta Tax Litigation Attorneys
Can the IRS Still Collect After the Government Wins a Federal Tax Judgment?
Yes. IRS guidance confirms that reducing a tax assessment to judgment does not eliminate the underlying assessment or end IRS administrative collection authority. The government retains both judicial enforcement tools and existing IRS collection mechanisms.
Can My CPA Represent Me in a Federal District Court Tax Lawsuit?
No. Federal district court litigation requires an attorney admitted to practice before that court. A CPA may handle IRS correspondence, tax preparation, and certain administrative proceedings. Federal court filings, discovery, and trial preparation fall outside the scope of accounting practice.
Can a Federal Tax Lawsuit Involve Property Owned With Someone Else?
Yes, depending on the circumstances. DOJ collection litigation may target a taxpayer's interest in jointly held property. It may also involve nominee, transferee, or alter-ego claims against third parties the government believes hold property on the taxpayer's behalf.
Is My Federal Tax Case Public Record?
Generally, yes. Federal civil cases, including tax collection suits, appear in public court records that are accessible through the court's electronic filing system. Certain materials may be sealed or redacted. Taxpayers with confidentiality concerns may discuss available procedural options with their attorney.
What Is the Difference Between a Tax Controversy Attorney and a Tax Litigation Attorney?
A tax controversy lawyer handles disputes with the IRS at the administrative level, including audits, appeals, and collection negotiations. A tax litigation attorney handles cases that reach federal court. At Wiggam Law, we handle both stages. A case that begins as a tax controversy and escalates to litigation stays with the same firm.
