Tax Avoidance Strategies in Multinational Corporations

Tax avoidance entails a series of legal engineering maneuvers (tax planning) conducted by companies to minimize their tax burden without literally violating the law. This practice is incredibly popular among multinational corporations operating across multiple jurisdictions with asymmetrical tax rate regimes. This topic serves as a gold mine for empirical tax accounting research.

The Transfer Pricing Mechanism

One of the most dominant strategies is Transfer Pricing, the pricing of transactions between related parties (intercompany transactions). Multinational companies can 'shift' profits from high-tax countries to low-tax countries (tax havens) by manipulating the transfer prices of goods, services, or intellectual royalties (intangible assets). Researchers frequently dissect the arm's length principle as an indicator of tax aggressiveness.

Thin Capitalization Practices

The second strategy is Thin Capitalization, which involves financing a subsidiary's operations using an exceedingly large portion of inter-company debt rather than equity capital. Because interest expense is a tax-deductible element, a subsidiary in a high-tax country can negate its taxable income by paying exorbitant interest to the parent company in a tax haven.

Measurement Proxies in Theses

How do researchers measure something that is intentionally hidden? Academic literature generally employs the Cash Effective Tax Rate (CETR) (Cash taxes paid divided by Pre-Tax Income) or Book-Tax Differences (BTD) (The difference between accounting income and taxable income) as proxies. The lower the CETR value compared to the statutory tax rate, the higher the indication of tax avoidance. Through NgepetData, Current Tax and Pre-Tax Income values from hundreds of financial reports can be extracted instantly to generate CETR metrics ready for regression.
