Which cost basis method minimizes taxes?

Specific identification lets you choose highest-cost lots to minimize gains or maximize losses. FIFO often results in the largest gains in rising markets. Average cost is simple but inflexible.

What happens to cost basis when I inherit stock?

Inherited assets receive a step-up in basis to fair market value at the date of death. Heirs can sell immediately with no capital gains tax regardless of the original purchase price.

How does a stock split affect cost basis?

In a 2:1 split, you have twice the shares at half the per-share basis. Total cost basis is unchanged. Example: 100 shares at $50 basis becomes 200 shares at $25 basis.
