Tax Forms

Operational skill for preparing supporting schedules and specialized forms that attach to the federal Form 1120 corporate tax return. Covers depreciation, capital transactions, foreign tax credits, intercompany compliance, investment reporting, and digital assets.

Depreciation and Amortization (Form 4562)

Section 179 Expensing

Allows immediate deduction of qualifying tangible personal property, QIP, and certain real property improvements (roofs, HVAC, fire protection, security systems). Limited by three caps: dollar limit ($1,250,000 for 2025), investment phase-out threshold ($3,130,000 for 2025), and taxable income from active trades or businesses. Excess carries forward indefinitely. SUV limit ($31,300 for 2025) applies to vehicles over 6,000 lbs GVW classified as SUVs.

For C-corporations, the taxable income limitation is computed at the corporate level (before the Section 179 deduction). Section 179 is a tax election only -- book depreciation follows GAAP straight-line, creating a temporary book-tax difference.

Bonus Depreciation Phase-Down

Applies to MACRS property with recovery period of 20 years or less, QIP, computer software, and water utility property. Both new and used property eligible (used property since 9/27/2017 under TCJA).

Key 2025 rule: P.L. 119-21 restored 100% bonus for property acquired and placed in service after January 19, 2025. Property acquired before that date but placed in service in 2025 follows the 40% rate. Elect-out is per-class, per-year, irrevocable.

Phase-down trajectory: 100% (2017-2022), 80% (2023), 60% (2024), 100% restored post-1/19/2025, 20% (2026), 0% (2027+) absent new legislation.

MACRS Property Classes

GDS (default) uses 200% DB for 3-20 year property and straight-line for 27.5+ year property. ADS required for foreign-use property, tax-exempt use/bond-financed property, and Section 163(j) electing real property trades. Key classes:

• 5-year: computers, office equipment, autos, light trucks
• 7-year: office furniture, fixtures, property without class life
• 15-year: QIP, land improvements, telephone distribution
• 39-year: nonresidential real property (straight-line, mid-month convention)

Conventions

• Half-year (default for personal property) -- first/last year deduction is half
• Mid-quarter (triggered when >40% of depreciable basis placed in service in Q4) -- all property that year uses quarter-specific factors (Q1=87.5%, Q2=62.5%, Q3=37.5%, Q4=12.5%)
• Mid-month (real property only) -- 27.5-year and 39-year classes

Listed Property

Passenger automobiles, transportation property with personal use potential, and entertainment/recreation property. Must exceed 50% qualified business use for accelerated depreciation or Section 179. Investment use does not count toward the 50% threshold. If business use drops to 50% or below, recapture excess depreciation and switch to ADS straight-line. Annual auto depreciation caps apply regardless of MACRS class ($20,400 with bonus / $12,400 without for 2024).

Amortization

• Section 197 intangibles (goodwill, covenants not to compete, customer lists, patents, trademarks): 15-year straight-line
• Section 174 R&E (2025+ per P.L. 119-21): domestic R&E deductible currently or amortized 60+ months; foreign R&E amortized 15 years. For 2022-2024: all Section 174 costs capitalized (5-year domestic, 15-year foreign)
• Startup/organizational costs: $5,000 immediate (if total <$50,000), remainder over 180 months

Decision Points

1. Section 179 vs. bonus -- Section 179 is limited by business income; bonus is not. For profitable corps, bonus is simpler
2. Elect out of bonus? -- preserves depreciation for future high-income years
3. Mid-quarter convention triggered? -- check Q4 placements before year-end acquisitions
4. GDS or ADS? -- ADS required in specific situations; otherwise GDS provides faster recovery

Capital Gains and Losses (Form 8949 / Schedule D)

Form 8949 Structure

Part I (short-term, held 1 year or less): Box A (1099-B with basis reported, no adjustments), Box B (1099-B without basis), Box C (no 1099-B). Part II (long-term, held more than 1 year): Boxes D/E/F mirror A/B/C.

Adjustment codes in column (f): W (wash sale), B (incorrect basis), T (wrong holding period), O (other), S (gross vs. net proceeds), N (noncovered security), H (short sale holding period). Multiple codes can combine on one line.

Corporate Capital Gains Rules

C-corporations receive no preferential capital gains rate -- all gains taxed at the flat 21% rate (post-TCJA). The short-term/long-term distinction matters only for netting gains against losses and tracking carryback/carryforward character.

Capital losses deduct only against capital gains -- no deduction against ordinary income (individuals get $3,000; corporations get none). Net capital loss carries back 3 years, then forward 5 years, always treated as short-term in the destination year.

Schedule D Flow

Form 8949 totals flow to Schedule D Part I (lines 1a/1b/2) and Part II (lines 8a/8b/9). Schedule D adds installment sales (Form 6252), like-kind exchanges (Form 8824), pass-through gains/losses, capital gain distributions, and carryovers. Line 17 net result flows to Form 1120 Line 8 (if positive; zero if net loss).

Box A/D transactions with no adjustments can skip Form 8949 and report directly on Schedule D.

Section 1231 Interaction

Depreciable/real business property held >1 year: net Section 1231 gain is long-term capital gain (flows to Schedule D); net Section 1231 loss is ordinary (fully deductible, bypasses capital loss limitation). Apply the 5-year lookback -- current 1231 gains recharacterized as ordinary to the extent of unrecaptured 1231 losses from prior 5 years. Depreciation recapture (Section 1245 for personal property, Section 1250 + Section 291 additional 20% for corporate real property) applies before 1231 netting.

Wash Sale Rule (Section 1091)

Applies to corporations. Loss disallowed when substantially identical security repurchased within 30 days before/after sale (61-day window). Disallowed loss adds to replacement security basis; holding period tacks on. Report with code W on Form 8949. Related party purchases (>50% ownership) can trigger wash sales for corporations.

Cost Basis Methods

• Specific identification: most flexibility, requires contemporaneous documentation
• FIFO (default): oldest shares sold first
• Average cost: mutual fund/DRIP shares only (not individual stocks or ETFs)

Decision Points

1. Any adjustment codes needed? -- compare 1099-B basis to taxpayer records, check for wash sales
2. Specific ID vs. FIFO? -- specific identification optimizes loss timing for carryback/carryforward planning
3. Net capital loss? -- compute carryback eligibility (3 years back), track carryforward (5 years, then expires)
4. Waive carryback? -- only beneficial if carryforward years have higher capital gains; election is irrevocable
5. Capital loss carryforward expiring? -- plan asset sales to generate offsetting gains before the 5-year window closes

Foreign Tax Credit (Form 1118)

Separate Limitation Categories

A separate Form 1118 is required for each applicable category:

• Section 951A (GILTI) -- no carryback or carryforward of excess credits
• Foreign branch income -- QBU business profits, excluding passive income
• Passive category -- foreign personal holding company income (dividends, interest, rents, royalties, gains), with exceptions for financial services and active rents/royalties
• General category -- residual; includes high-taxed passive income reclassified via HTKO
• Section 901(j) -- sanctioned country income
• Treaty-resourced -- U.S.-source income re-sourced as foreign under treaty

Credit Computation

Limitation per category: (foreign-source taxable income in category / worldwide taxable income) x U.S. tax. Eligible taxes: income, war profits, excess profits taxes paid or accrued to foreign countries; taxes deemed paid under Section 960 for CFC inclusions. Section 78 gross-up: deemed-paid taxes added to gross income to properly compute the limitation numerator.

High-Tax Kickout (HTKO)

Passive income reclassified to general category when the effective foreign tax rate exceeds the highest U.S. corporate rate (21% post-TCJA).

Look-Through Rules (CFCs)

Dividends, interest, rents, and royalties from a CFC to a 10% U.S. shareholder are classified by the CFC's underlying earnings category, not automatically passive.

Carryback/Carryforward

Excess credits: carry back 1 year, then forward 10 years (same category). Exception: GILTI category credits have no carryback or carryforward. OFL/SLL accounts track situations where foreign losses offset U.S.-source income, requiring future recapture.

Foreign Tax Redeterminations

Redetermine credit when: accrued taxes differ from amounts paid, taxes unpaid within 24 months of year-end, foreign taxes refunded, or CFC inclusions change.

Section 960(d)(4) (New for 2025)

Disallows 10% of foreign income taxes on PTEP distributions attributable to prior Section 951A inclusions.

Intercompany and Related-Party Compliance

Related Party Definition (IRC 267(b))

Related parties include: individual and >50%-owned corporation, two corporations in the same controlled group (>50% common ownership), corporation and partnership with >50% common owners. Constructive ownership rules (IRC 267(c)) expand ownership through family, partnerships, estates/trusts, corporations (50%+ shareholders), and options.

Section 267 Loss Disallowance

Losses on related-party sales are disallowed (not deferred). Recovery only when the buyer sells to an unrelated third party -- buyer's gain reduced by previously disallowed loss (not below zero). If the buyer later sells at a loss to an unrelated party, the disallowed loss is permanently lost.

Accrual-to-Cash Timing (Section 267(a)(2))

When an accrual-basis corporation accrues an expense to a cash-basis related party, deduction deferred until actually paid and includible in the payee's income. Common scenarios: year-end officer bonuses, management fees to related LLCs, interest on shareholder loans.

Form 5472 Reporting

Required when a 25% foreign-owned U.S. corporation has reportable transactions with a foreign related party. Also required for foreign-owned disregarded entities (since 2017). Separate Form 5472 for each foreign related party.

Reportable transactions (Parts IV/V/VI): sales/purchases of property, rents, royalties, services, commissions, interest, insurance premiums, PCT/CST payments, nonmonetary transactions at FMV, and related-party debt balances.

Penalty: $25,000 per form (post-TCJA; was $10,000), plus $25,000 per 30-day period after IRS notification, no cap. Reasonable cause defense is narrow.

Intercompany Loans (IRC 7872/AFR)

Must charge adequate stated interest at or above AFR. Below-market loans trigger imputed interest. Demand loans at short-term AFR (recomputed annually); term loans at AFR for applicable term on loan date. No $10,000 gift loan exception for corporation-shareholder loans.

Transfer Pricing (Section 482)

Methods (Best Method Rule -- No Hierarchy)

1. CUP -- direct price comparison; strongest when exact comparables exist
2. Resale price -- resale price minus appropriate gross profit margin; best for limited-function distributors
3. Cost plus -- costs plus appropriate markup; best for contract/toll manufacturers
4. Comparable profits (CPM/TNMM) -- net profit margin comparison using PLIs; most commonly used due to data availability
5. Profit split -- allocate combined profit by relative contributions; for highly integrated operations with significant intangibles on both sides

Documentation for Penalty Protection (Reg. 1.6662-6)

Contemporaneous documentation (by return due date with extensions): organizational structure, controlled transaction description, comparability analysis, best method selection and application, economic analysis, document index. Late-created documentation does not qualify for penalty protection.

Penalties

• 20% substantial valuation misstatement: transfer price 200%+ (or 50%-) of correct price, net adjustment >$5M or 10% gross receipts
• 40% gross valuation misstatement: transfer price 400%+ (or 25%-) of correct price, net adjustment >$20M or 20% gross receipts
• Contemporaneous documentation creates rebuttable presumption of reasonable cause

APAs

Binding IRS-taxpayer agreements on transfer pricing method. Unilateral (IRS only), bilateral (IRS + one foreign authority), multilateral. Typical term: 5 prospective years with rollback. User fee: $113,500 large cases, $56,750 small. Timeline: 12-24 months unilateral, 24-48 months bilateral.

BEAT (Section 59A)

Base erosion payments to foreign related parties create minimum tax exposure. Threshold: $500M average annual gross receipts, 3% base erosion percentage. BEAT applies regardless of arm's length pricing.

Investment Tax Reporting

1099 Processing

• 1099-DIV: Box 1a ordinary dividends (1b qualified subset), Box 2a capital gain distributions, Box 3 return of capital (reduces basis), Box 4 federal withholding, Box 11 tax-exempt interest
• 1099-B: Sales data flows to Form 8949. Reconcile broker-reported basis against taxpayer records before filing. Aggregate by holding period for Schedule D
• 1099-INT: Taxable and tax-exempt interest segregation

Brokerage Reconciliation

Match brokerage statements to the accounting system's investment accounts at cost basis. The accounting system tracks cost basis; unrealized gains are off-book until disposition. Maintain lot-level detail in a supplemental schedule (most accounting systems do not natively track individual security lots).

Separate income accounts by type: Short-Term Capital Gains, Long-Term Capital Gains, Short-Term Capital Losses, Long-Term Capital Losses, Qualified Dividends, Ordinary Dividends, Taxable Interest, Tax-Exempt Interest. For account setup and journal entry mechanics, invoke qbo-integration:qbo-bookkeeping.

Digital Asset Compliance

Tax Classification

Digital assets (cryptocurrency, NFTs, stablecoins, tokenized securities) are property under Notice 2014-21. Every disposition is a realization event. For C-corporations, short-term/long-term distinction affects only character and capital loss limitation analysis, not the tax rate (flat 21%).

Taxable Events

Sale for fiat, exchange for another digital asset, payment for goods/services, receipt as payment (ordinary income at FMV), mining rewards (ordinary income when dominion and control established), staking rewards (ordinary income at FMV when received -- IRS position), hard forks with airdrop (ordinary income per Rev. Rul. 2019-24).

NOT taxable: purchasing with fiat, wallet-to-wallet transfers, soft forks without new assets.

Cost Basis

• Specific identification (preferred): requires lot-level tracking with transaction hashes and wallet addresses
• FIFO (default if specific ID not established)
• Average cost is NOT available for digital assets

Wash Sale Exemption

IRC Section 1091 currently does not apply to digital assets. A corporation can sell crypto at a loss and immediately repurchase without deferral. Monitor pending legislation that would extend wash sale rules to digital assets.

Reporting

Form 1120 mandatory digital asset question (since TY2023). Dispositions on Form 8949/Schedule D. Form 1099-DA (new TY2025+) from custodial brokers -- reconcile against internal records. FIFO becomes default for broker-reported basis if no specific identification election made with the broker.

Accounting System Integration Notes

• Fixed assets at cost basis; depreciation via journal entries (the accounting system does not compute MACRS). Section 179 is a tax election creating a book-tax difference
• Capital gains/losses in separate accounts by holding period; wash sale adjustments are tax-only (book tracks original cost, tax tracks adjusted)
• Foreign taxes paid to an expense account; Section 78 gross-up is return-level only
• Intercompany due-to/from balance sheet accounts reconciled monthly; management fee allocations documented in JE memos
• Digital assets as separate Other Current Asset accounts per holding; lot tracking in supplemental schedule or crypto tax software
• Investment accounts reconciled to brokerage at cost basis; 1099 totals tied to year-end balances

For platform-specific account setup, journal entry creation, and reporting, invoke the appropriate qbo-integration skill.
