Tax Lawyers Email List for IRS dispute and tax planning counsel

Tax work covered

Which tax lawyers does the email list include?

The list includes attorneys whose records carry the tax practice area, from IRS audit and collection counsel to Tax Court litigators and deal planners. The IRS closed 497,621 return audits in fiscal year 2025, and the US Tax Court received 18,549 new cases that year.

The Tax Court's FY 2027 budget justification reports that taxpayers represented themselves in approximately 78% of the cases filed in fiscal year 2025, and that 11,112 of the 18,549 filings were regular cases rather than small tax cases.

Transactional tax work follows the deal. Property sales put tax counsel beside real property law firm contacts, and company acquisitions put them beside M&A attorney contacts.

What do tax law firms buy?

Tax law firms buy tax research services, IRS authorization tools, court e-filing support and return preparation software. Their work runs through federal systems: Form 2848 authorizations in the IRS Centralized Authorization File, and petitions in DAWSON, the Tax Court's electronic filing and case management system.

• Authorization tools connect to the IRS Tax Pro Account, where most authorization requests record immediately to the Centralized Authorization File.
• Court filing support fits DAWSON, which took 12,973 of the Tax Court's 18,549 fiscal year 2025 petitions electronically.
• Return preparation software serves attorneys who prepare federal returns for pay and therefore hold a 2026 PTIN, which costs $18.75.
• Tax research services follow the Tax Court's output, which reached 187 opinions in fiscal year 2025.

IRS practice rights

Who can practice before the IRS under Circular 230?

Attorneys, certified public accountants and enrolled agents hold unlimited representation rights before the IRS. Under Circular 230 at 31 CFR 10.3, an attorney not under IRS suspension or disbarment practices by filing a written declaration of qualification and authority, made in Part II of Form 2848.

Circular 230 defines an attorney as a member in good standing of the bar of the highest court of any state, territory, possession or the District of Columbia. On Form 2848, an attorney uses designation a and enters the 2-letter licensing jurisdiction with the bar or license number.

The IRS assigns each representative a Centralized Authorization File (CAF) number: 9 digits, separate from the SSN, EIN and PTIN, and not by itself proof of authority to practice. A PTIN is a separate duty that applies to anyone who prepares federal tax returns for compensation.

The U.S. Tax Court keeps its own bar. Attorneys apply on Form 30 with a $50 fee and a certificate of good standing issued within 90 calendar days, while nonattorneys qualify by passing the Court's examination under Rule 200. By statute, the Court has 19 judges appointed by the President to 15-year terms.
