FASB #96
Assume year 3 taxable income = $9,000 x .3 = tax payable of $2,700.
Now reversal: year 4 excess still $4,000 x .3 = $1,200.
- Total liability should now be $1,200.
- Liability already carries a balance of $3,000. You must adjust to the correct balance.
Deferred tax liability 1,800
Next year should completely reverse out.
