Practical signals that predict a good Indianapolis tax and IRS lawyer:
U.S. Tax Court Indianapolis trial sessions. The U.S. Tax Court holds trial sessions in Indianapolis on a recurring calendar. Petitions must be filed in Washington, D.C., but cases involving Indianapolis taxpayers are tried locally.
Indiana Tax Court. Indiana has a dedicated Indiana Tax Court (one of only a handful of states with one). Indiana Tax Court hears appeals of final determinations from the Department of Revenue. Practice there is its own discipline.
Indiana Department of Revenue audits. The Indiana Department of Revenue audits both individuals and businesses. Indiana follows federal adjustments closely — a federal audit frequently triggers an Indiana letter.
Indianapolis Public-Finance Tax Bar. Indianapolis has one of the larger public-finance and tax-exempt bond bars in the Midwest, anchored by Ice Miller's national municipal bond practice.

Most Indianapolis tax and IRS lawyers are competent. A few patterns predict trouble:
"Pennies on the dollar" guarantees. Marketed by national tax-resolution firms; not a real legal claim. Offers in compromise are case-specific and tightly constrained by IRS rules.
Will not put fee scope in writing. Tax controversy work scales — refusing to scope ranges is a red flag at any firm.
No U.S. Tax Court bar admission. If the matter may end up in Tax Court, your lawyer needs that admission. Verify before signing.
Confuses CPA work with legal work. Tax lawyers and tax CPAs do different things. Audit defense and structuring are legal work. Return preparation is CPA work.
Most Indianapolis firms on this list offer a free initial inquiry call. Use it. Bring a list of questions and write down the answers. Compare across at least two firms before you sign.
CPAs prepare returns and handle most routine compliance. Tax lawyers handle audits, appeals, Tax Court, and structuring decisions. Many matters need both — coordinated.
Simple individual audits $3,500–$15,000. Multi-issue business audits $15,000–$75,000+. Criminal investigations $50,000–$500,000+.
Field audits typically run 6–24 months from notice to closure. Correspondence audits resolve faster. Appeals add 6–18 months. Tax Court adds another 12–36 months.
Technically yes, but Tax Court is a federal trial court with formal procedures. The IRS is represented by experienced government tax lawyers. Self-representation is rarely a good outcome.
A formal proposal to the IRS to settle a tax debt for less than the full amount based on doubt as to collectibility, doubt as to liability, or effective tax administration. Approval rates are roughly 30-40%.
Boutique tax partners $300–$500. Mid-size firm tax partners $400–$750. AmLaw tax partners $550–$1,200.
Yes — after issuing a Final Notice of Intent to Levy and waiting 30 days. A timely Collection Due Process appeal pauses collection. This is one of the most time-sensitive points in any IRS case.
Yes. The IRS routinely shares audit adjustments with state tax authorities, and Indiana does the same in reverse. A federal audit frequently triggers a state audit, and vice versa.
One last thing. Choosing a lawyer is personal. Read the reviews. Call two or three firms before you sign. Ask each one: How many matters like mine have you handled in the last three years? The answer tells you a lot. — The LawFirmSquare team
