The credential is only the first filter. Match the professional's actual experience to the stage: return preparation, examination, collection financial analysis, payroll tax, administrative Appeals, Tax Court, bankruptcy, or potential criminal exposure.
“Defense” on this independent educational site means preparing an accurate record, understanding public rights and procedures, and choosing an official response channel. The site does not defend or represent taxpayers and does not review private files.
Start with four facts
Exact notice, letter, form, report, lien, levy, or court document.
Taxpayer, entity, form, tax period, amount, and requested action.
Notice date, response date, filing date, and objective delivery proof.
Return, transcript, payment, financial, or issue-specific evidence.
Important distinctions
Tax attorney
May be useful for legal analysis, privilege, litigation, complex disputes, bankruptcy interaction, or potential civil or criminal exposure. Verify admission and relevant tax experience.
Certified public accountant
May be useful for accounting reconstruction, returns, financial statements, audits, and representation when appropriately licensed and experienced.
Enrolled agent
A federally authorized tax practitioner with unlimited practice rights before the IRS. Verify current enrollment and experience with the specific matter.
LITC or TAS
An LITC may provide independent representation subject to eligibility and capacity. TAS may help with qualifying hardship, delay, or IRS system problems; it is not private counsel.
