In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740), “Simplifying the Accounting for Income Taxes”.

The standard also simplifies accounting for income taxes under U.S. GAAP by clarifying and amending existing guidance, including the recognition of deferred taxes for goodwill, the allocation of taxes to members of a consolidated group and requiring that an entity reflect the effect of enacted changes in tax laws or rates in the annual effective tax rate computation in the interim period that includes the enactment date.
