Individual Income Tax: How Are Returns Filed and Disputes Resolved?

IRS Form 1040 reports wage income (W-2), self-employment income (Schedule C), investment income (Schedule B and D), and partnership or S-corp income (Schedule E). Filing status (single, MFJ, MFS, head of household, qualifying widower) determines bracket thresholds and standard deductions. Wage withholding, estimated tax payments, and quarterly installments avoid underpayment penalties under IRC § 6654. Cryptocurrency reporting under Form 1040 digital asset question requires affirmative response and Schedule D disclosure. Strong federal income tax counsel matches reporting strategy to each taxpayer's income profile.

Self-employment tax under IRC § 1401 imposes 15.3% combined Social Security and Medicare tax on net self-employment earnings up to $168,600 (2024 wage base). Quarterly estimated tax payments (Form 1040-ES) due April 15, June 15, September 15, and January 15 prevent underpayment penalties. W-2 wage withholding under IRC § 3402 ensures employer-level tax collection for most employees. Annual reconciliation through Form 1040 determines whether refund or additional payment is due. Coordinated income tax compliance counsel calibrates withholding and estimated payments to minimize year-end surprise.

Standard deduction for 2024 ($14,600 single, $29,200 married filing jointly) eliminates itemizing for most taxpayers. Itemized deductions on Schedule A include SALT (capped at $10,000), mortgage interest, charitable contributions, and medical expenses exceeding 7.5% of AGI. Above-the-line deductions (HSA contributions, student loan interest, IRA contributions) reduce AGI before standard or itemized deduction. Tax credits (Child Tax Credit, EITC, education credits) reduce tax dollar-for-dollar after deductions. Strong income tax planning counsel evaluates each deduction stack against the taxpayer's full picture.

FBAR (FinCEN Form 114) requires reporting of foreign financial accounts exceeding $10,000 aggregate at any time during the year. FATCA Form 8938 reports specified foreign financial assets above $50,000 (single, end of year) under IRC § 6038D. Foreign earned income exclusion (FEIE, IRC § 911) excludes up to $126,500 (2024) of foreign earned income for qualifying expats. Streamlined Filing Compliance Procedures offer reduced-penalty resolution for non-willful FBAR delinquencies. Coordinated FBAR reporting counsel manages dual disclosure obligations to FinCEN and IRS simultaneously.

Correspondence audits handle simple documentation issues by mail, while office and field audits address more complex returns through in-person examination. Statute of limitations under IRC § 6501 runs three years from return filing, six years for 25% or greater omissions, unlimited for fraud. Information document requests (IDRs) require careful response with privilege review and document preservation. Audit reconsideration and protest procedures preserve appeal rights when initial audit results are unfavorable. Strong IRS audit defense counsel manages information exchange and response strategy throughout examination.

Accuracy-related penalties under IRC § 6662 impose 20% on underpayments from negligence, substantial understatement, or substantial valuation misstatement. Fraud penalties under IRC § 6663 impose 75% civil penalty when underpayment results from intentional fraud. Criminal tax violations under IRC § 7201 (tax evasion) and § 7206 (false return) carry up to 5 years imprisonment plus fines. Failure-to-file (§ 6651), failure-to-pay, and trust fund recovery penalties add to civil exposure. Coordinated criminal tax defense counsel manages parallel civil and criminal exposure simultaneously.

IRS Office of Appeals provides independent review of audit determinations with settlement authority for civil tax controversies. U.S. Tax Court (deficiency jurisdiction) allows pre-payment litigation without paying the assessed tax first. District Court and Court of Federal Claims (refund jurisdiction) require full payment before refund suit but offer jury trial options. Tax Court memorandum opinions and full opinions create precedent on substantive tax issues. Strong tax controversy and litigation counsel selects forum based on issue, payment posture, and precedent landscape.

Installment agreements under IRC § 6159 spread tax debt over up to 72 months for streamlined balances and longer for partial-pay arrangements. Offers in compromise under § 7122 settle tax debt for less than full amount based on reasonable collection potential analysis. Currently not collectible (CNC) status pauses collection when payment causes economic hardship. Bankruptcy may discharge certain income tax debt meeting three-year, 240-day, and assessment timing requirements. Coordinated tax disputes counsel matches each taxpayer to the right resolution path.
