Kelly, Tammy and Matthew = $100,000 each
Matthew and Joshua own 50% of stock of Best each.
Best’s income is $425,000
Tax liability for Best’s stockholders
Joshua = 425,000/2 = $212500
Tax liability of Matthew = $212500
Total Tax liabilities
Matthew = 212500 + 100,000 =$312500
Kelly = $100,000
Tammy = $100,000
Joshua = $212500
In the above case, Matthew’s taxable income will include his share of stock in both Avis and Best. His tax liability will be $312500. Kelly and Tammy’s will be $100,000 and Joshua’s liability will be $212500.
Avis’s Taxable Income = $300,000
Avis own 85% of Best’s Income = 0.85 * 425,000 = $361250
Total Tax Liability of Avis = $661250
Tax Liability of Best = 0.15* 425,000 = $63750
