Ch8. IRS Audits & Appeals — Tax Controversy and Taxpayer Rights

IRS Examinations (Audits)

Correspondence Exam:
Most common type — conducted entirely by mail
Typically limited to one or two items on the return

Office Exam:
Taxpayer comes to IRS office
Broader scope than correspondence

Field Exam:
IRS agent comes to taxpayer's home or business
Largest and most complex cases

Examination Triggers:
Computer scoring (DIF score) — statistical anomalies
Random selection
Whistleblower reports
Related-party compliance (if related return is audited)

Taxpayer Rights (Taxpayer Bill of Rights):
Right to be informed (Publication 1)
Right to quality service
Right to representation (by CPA, attorney, or enrolled agent)
Right to finality (limits on repeated exams of same issue)

Pre-Assessment Procedures

30-Day Letter:
Issued after exam concludes — proposes adjustments
Taxpayer has 30 days to agree or request Appeals conference
Options: agree and pay; protest to IRS Appeals; do nothing (90-day letter follows)

90-Day Letter (Statutory Notice of Deficiency — "Ticket to Tax Court"):
If no agreement reached after 30-day letter
Taxpayer must petition Tax Court within 90 days to contest without paying first
Miss the 90-day deadline → assessment becomes final

Pre-assessment Review:
Request a conference with the IRS exam supervisor or Appeals
Most effective intervention before formal assessment
No payment required during the process

IRS Appeals and Tax Court Procedures

IRS Appeals Office:
Independent from examination function
File a written protest within 30 days of 30-day letter (for large cases)
Small case request (≤$25,000) — simpler process
~60% of cases are resolved at Appeals level

U.S. Tax Court:
File petition within 90 days of Statutory Notice of Deficiency
No payment required before litigating
Small Tax Case Division (S-Case): ≤$50,000 per year, informal, no appeal
Regular Division: standard cases, full trial, can appeal to Circuit Court

Other Litigation Forums:
U.S. District Court: must pay tax first, then sue for refund
U.S. Court of Federal Claims: must pay tax first, then file claim
Advantage of paying first: jury trial available in District Court

Collection Due Process (CDP):
Notice of Federal Tax Lien or Notice of Intent to Levy triggers CDP rights
Request CDP hearing within 30 days (for levy notices) or within 30 days of lien notice
Raise installment agreement, OIC, innocent spouse, or other collection alternatives

Penalties and Statute of Limitations

Key Penalties:
Failure to file: 5% per month (max 25%) of unpaid tax
Failure to pay: 0.5% per month (max 25%) of unpaid tax
Accuracy-related penalty: 20% of underpayment (negligence or substantial understatement)
Fraud penalty: 75% of underpayment

Statute of Limitations (SOL):
General assessment SOL: 3 years from filing date
Substantial omission (>25% of gross income): 6 years
Fraud or willful evasion: no SOL (can assess at any time)
Refund claim: 3 years from filing or 2 years from payment (whichever is later)

Offer in Compromise (OIC):
Doubt as to collectability: IRS may accept less than full liability
Effective Tax Administration: exceptional circumstances
Must be in compliance (all returns filed, current on estimated payments)

Tax Appeals Hierarchy: Exam → Appeals → Tax Court → Circuit ★★★★★ : Must exhaust administrative remedies before litigation; Tax Court requires no prepayment. Memory hook: Exam → 30-day → 90-day → Tax Court

90-Day Letter = Statutory Notice of Deficiency ★★★★★ : The “ticket to Tax Court.” Miss the deadline → assessment final. No extensions. Memory hook: 90-day = last chance before assessment

Failure-to-File = 5%/month; Failure-to-Pay = 0.5%/month ★★★★☆ : FTF penalty 10× higher per month than FTP. Filing an extension avoids FTF but not FTP. Memory hook: File = 5%, Pay = 0.5% — file on time even if you can’t pay

Practice Quiz

Q. What is the difference between IRS Appeals and Tax Court?

IRS Appeals is an administrative body within the IRS — informal, no payment required, and resolves about 60% of cases. If Appeals fails, the taxpayer receives a 90-day letter (Statutory Notice of Deficiency) and can petition the U.S. Tax Court within 90 days without paying the disputed tax first. The Tax Court is a federal court specializing exclusively in tax cases. Its decisions can be appealed to the applicable Circuit Court of Appeals and ultimately to the U.S. Supreme Court. Unlike district court (where full payment is required before litigation), Tax Court lets taxpayers contest without upfront payment, making it the most common litigation forum.

Q. Why is EA / CPA representation so valuable during an IRS audit?

Taxpayers faced with an IRS audit find it difficult to navigate alone due to the complexity of tax law. Enrolled Agents (and CPAs/attorneys authorized to practice before the IRS) can represent clients at all administrative levels — examination, appeals, and collections. At the exam stage, a representative controls what information the IRS receives, negotiates scope limitations, and prevents taxpayers from voluntarily providing damaging information. At Appeals, represented taxpayers achieve significantly better outcomes than those who represent themselves. IRS representation is an Enrolled Agent’s core exclusive practice right.
