[ANSWERED] Estate Planning: Size of Partial Gift Credit

In Reading 10, section 4.1.3, the curriculum says that the size of the partial gift credit = size of the gift x TgTe

However the formula works ONLY when the tax rates (Tg and Te) are equal. Am I doing something wrong or is there a fallacy in the formula???


The curriculum develops an example like this:

Scenario 1 - Partial gift and then bequest

Estate value = 500,000

Gift = 100,000

Gift Tax (40%) = 40,000

Total Disbursement = 100K +40K = 140,000

Taxable Estate = 500K - 140K = 360,000

Estate Tax (40%) = 144,000

Net After-Tax Amount = 216,000

After-Tax Estate + Gift = 216K + 100K = 316,000

Scenario 2 - all assets left in estate until bequeathed at death

Taxable Estate = 500,000

Estate Tax (40%) = 200,000

Net After-Tax Amount = 300,000

After-Tax Estate (+ Gift) = 300,000 (no gift in this scenario)

Gift credit Tax savings from gift = size of the gift x TgTe = 100,000 x 40% x 40% = 16,000

which is exactly = 316,000 - 300,000 = 16,000


However, if I pick different rates (say 40% and 60%), here’s what you get:

Scenario 1 - Partial gift and then bequest

Estate value = 500,000

Gift = 100,000

Gift Tax (40%) = 40,000

Total Disbursement = 100K +40K = 140,000

Taxable Estate = 500K - 140K = 360,000

Estate Tax (60%) = 216,000

Net After-Tax Amount = 144,000

After-Tax Estate + Gift = 144K + 100K = 244,000

Scenario 2 - all assets left in estate until bequeathed at death

Taxable Estate = 500,000

Estate Tax (60%) = 300,000

Net After-Tax Amount = 200,000

After-Tax Estate (+ Gift) = 200,000 (no gift in this scenario)

Gift credit Tax savings from gift = size of the gift x TgTe = 100,000 x 40% x 60% = 24,000

But 244,000 - 200,000 = 44,000 ≠ 24,000 … ???


When I develop the calculations of the example, I see that actually

tax savings = size of gift x [1 - (1+Tg) x (1-Te)]… and the formula given in the curriculum works only for Tg=Te

So… is the curriculum teaching completely wrong stuff!!! I’m losing my mind… Please help!

I was right. They will issue an erratum:

… not sure if I did a favor to the other candidates by reporting this mistake… whatever
