Analytical Proof & Invariants

Machine Precision

Governing Mathematical Formula:

Net Capital Gain/Loss = Realized Gains - Realized Losses | Offset Limit = $3,000 against Ordinary Income

Step-by-Step Mathematical Derivation

Dollar-for-Dollar Capital Gain Erasure

Harvested capital losses offset capital gains dollar-for-dollar without any cap: $24,000 gains - $24,000 losses = $0 taxable capital gains.

The $3,000 Ordinary Income Offset

Under IRC Section 1211, excess losses over gains can offset up to $3,000 of ordinary W-2 income ($1,500 MFS) per tax year.

Indefinite Loss Carryforward

Any remaining unabsorbed losses ($32,000 - $24,000 - $3,000 = $5,000) carry forward indefinitely to offset future gains in subsequent tax years.

Frequently Asked Questions

What is the IRS Wash-Sale Rule? +

Under IRC Section 1091, you cannot claim a tax loss if you repurchase the exact same security (or a 'substantially identical' stock or option) within 30 days before or 30 days after the sale date (61-day total window).

Can you avoid the wash-sale rule using ETFs? +

Yes! Investors sell a losing index fund (e.g. Vanguard S&P 500 VOO) and immediately purchase a similar but not identical fund (e.g. Schwab US Large-Cap SCHX or Vanguard Total Stock VTI) to harvest the tax loss while remaining 100% invested in the market.
