Example Output

Example 1: IRC § 162 Deduction Analysis

Your position: Claiming $50K research and development expenses as ordinary business expenses.

Risk assessment: Moderate. IRS frequently challenges R&D deductions claiming they should be capitalized under § 263. However, strong case law supports deduction under § 162(a)(1) if expenses don't create an asset with useful life beyond the tax year. Your facts support current-year deduction: expenses for failed prototype testing.

Defense brief excerpt: "Under IRC § 162(a)(1), ordinary and necessary business expenses are deductible. The Supreme Court in Welch v. Helvering established a two-prong test: (1) the expense must be ordinary in the industry, and (2) necessary to the taxpayer's business. Taxpayer's R&D expenses satisfy both prongs. Reg. § 1.162-4 provides that costs incurred in unsuccessful research are generally deductible."


Example 2: Statute of Limitations Timeline

Facts: 2022 tax return filed April 15, 2023. Substantial understatement of income discovered during 2024 IRS examination.

Timeline generated:

  • Standard SOL expires: April 15, 2026
  • Extended SOL (25%+ understatement): April 15, 2027
  • Protective claim deadline: August 15, 2024
  • Hazard analysis due: 60 days from notice

Example 3: Capitalization vs. Expensing Challenge

Issue: $125K office renovation claimed as § 179 expense; IRS asserts it should be capitalized.

Defense argument: "Under IRC § 179 and TCJA amendments, eligible property placed in service during the tax year qualifies for immediate expensing. Reg. § 1.179-1(c) defines qualified property. Your renovation qualifies because: (1) property is tangible personal property, (2) placed in service date is documented as [DATE], and (3) total cost falls within the § 179 limit. CCA 200747003 supports expensing of similar office improvements where facts align with taxpayer's scenario."
