Overview

California lawmakers are contemplating a proposal for mandatory worldwide combined reporting, a policy the state previously abandoned in the 1980s due to significant opposition from international trading partners and the federal government. The proposal aims to change California's current approach to corporate taxation, which is based on formulary apportionment.

The current system allows states to apportion net income based on factors such as property, payroll, and sales. The proposed change would make California the only state to implement mandatory worldwide combined reporting, which raises concerns about the complexities and implications of such a shift.

Key details

  • The proposal revives a policy abandoned in the 1980s due to pushback.
  • California currently uses formulary apportionment for corporate income taxation.
  • Most states, including California, adopt a water’s edge approach for combined reporting.
  • Worldwide combined reporting would extend the unitary group concept beyond domestic borders.
  • States do not typically tax foreign companies without direct contacts in the state.
  • The proposal contrasts with the international practice of separate accounting for corporate profits.
  • Proponents argue that it addresses tax avoidance by multinational corporations.
  • Critics claim it complicates taxation and overlooks legitimate business operations abroad.
  • Existing transfer pricing rules already address issues related to profit-shifting.
  • California allows a water’s edge election, but few businesses opt for it.
