# Tax savings under FIFO vs. LIFO scheme

Here are the data. I am using semi-colons to indicate different years. There is no way of posting a pretty Excel sheet.

Years: 2002; 2001; 2000 Net Income (LIFO) : 3557; 3541; 3537 Inventory: 8781; 7204; 6351 LIFO Reserve: 3183; 2617; 2403 Tax rate: 20%; 30%; 30%

Question: What is the total tax savings that above company has generated through 2002 by using LIFO instead of FIFO Method?

My solution: Under FIFO, COGS would go down, so net income should go up.

Let’s first calculate net income under FIFO method.

Change in LIFO Reserve = (3183-2617=566); 2617-2403=214; for 2002 and 2001 respectively. New Net Income under FIFO = 3557 + .8*566 = 4009.8; 3541 + 0.7*214 = 3690.8 for 2002 and 2001 respectively after factoring the taxes on change in LIFO Reserve (i.e. COGS savings).

Therefore, tax savings would be additional tax paid under FIFO scheme (= the tax saved by using LIFO scheme) = (0.2 * 566) + (0.3 * 214) = 113.2 + 64.2 = 177.4

However, the answer is 898.3. Official answer says that tax savings = 566*0.2 + 0.3*2671. I have no clue why the official answer uses 2671 (i.e. the entire LIFO reserve for 2001) to calculate tax savings. Wouldn’t we use 0.3*214? Moreover, the total tax paid under FIFO scheme would have been 177.4, so I am not sure whether tax savings of 898.3 even make any sense.

I’d appreciate thoughts. I am really lost. I have spent about 1.5 hours on trying to solve this, but ended up nowhere.

Read S2000’s answer. Basically, LIFO is cumulative. You are using the change in LIFO reserve in 2002 as well as previous years, which the entire 2001 LIFO is a total of.
