Why Accounting Standards Matter for Tax

In many countries, taxable income starts from accounting profit. The accounting framework used — whether IFRS, US GAAP, or a local standard like Germany's HGB — directly affects how income and expenses are measured. Understanding these differences is essential for accurate cross-border tax planning.

Key Areas of Divergence

Depreciation

IFRS uses economic useful life; many countries prescribe fixed tax depreciation rates that differ significantly.

Inventory Valuation

IFRS prohibits LIFO; US GAAP allows it, creating a tax advantage through lower taxable income in inflationary periods.

Lease Accounting

IFRS 16 puts operating leases on balance sheet, but tax treatment in most countries still follows the old rent deduction model.

R&D Costs

IFRS requires capitalizing development costs; many countries offer additional tax credits or super-deductions.

Provisions

Accounting provisions may not be tax-deductible until actually paid, creating temporary differences.

Revenue Recognition

IFRS 15 performance obligations may differ from when tax authorities consider revenue earned.

Transfer Pricing (OECD)

Businesses with related-party transactions across borders must price them at arm's length. The OECD provides five accepted methods:

  • Comparable Uncontrolled Price (CUP)
  • Resale Price Method
  • Cost Plus Method
  • Transactional Net Margin Method (TNMM)
  • Profit Split Method

Groups with consolidated revenue exceeding EUR 750M must file Country-by-Country Reports (BEPS Action 13).

Common Reporting Standard (CRS)

Over 100 jurisdictions participate in the OECD's automatic exchange of financial account information. Financial institutions report accounts held by foreign tax residents to local authorities, who share the data with the account holder's home country. The US participates through FATCA instead of CRS.
