Tax Loss Harvesting

If you have individual stocks or other securities that have a loss in them, you may have a tax planning opportunity: tax loss harvesting.

First off, it is important to keep in mind that tax loss harvesting only applies to assets (such as stocks, bonds, mutual funds, ETFs, etc.) in taxable accounts. It does not apply to assets in retirement accounts and health savings accounts.

If you have assets in taxable accounts that have declined in value relative to your purchase price, you have an opportunity to tax loss harvest. Here’s a basic example:

Example 1: Mark purchased 100 shares of Kramerica stock two years ago for $100 a share ($10,000 total). Based on a disappointing test of an oil-tanker bladder system, Kramerica’s stock is now worth $70 per share. If Mark sells all 100 shares for $70, his total basis in the stock ($10,000) exceeds the amount he realizes on the sale ($7,000) by $3,000.

In Mark’s case, he has a $3,000 capital loss for tax purposes. Capital gains and losses from the sale of property (for most individuals, from securities) are different for tax purposes than other types of income, such as wages, rents, self-employment income, interest, and dividends (collectively, usually referred to as “ordinary income”). Federal income tax law does two things to capital gains and losses. First, it taxes capital gains at a lower tax rate than most other types of income. Second, and most importantly for the purposes of tax loss harvesting, it limits the ability of a capital loss to offset ordinary income.

Capital losses, such as Mark’s loss on Kramerica stock, can offset either capital gains or ordinary income, but only to the extent of $3,000 ($1,500 if the taxpayer files married filing separate) of ordinary income a year.

Thus, tax loss harvesting is a great play in two situations:

  1. A taxpayer has a large capital gain in a taxable year; and,
  2. A taxpayer has ordinary income and can trigger a $3,000 capital loss.

A second example can illustrate the first situation.

Example 2: Lucy sells stock with a historic cost basis of $30,000 for $50,000 in March. Thus, she will have to report a $20,000 capital gain on her tax return. If, however, Lucy has another stock/bond/mutual fund/ETF with a historic cost of $100,000 and a fair market value of $80,000, and she sells it by year-end, she will harvest the $20,000 loss in time to offset the previous $20,000 gain.

Taxpayers with significant capital gains during a year should review their taxable accounts towards year-end to see if there are any opportunities to harvest losses and offset existing capital gains.

For those taxpayers without capital gains, there still can be some opportunity to tax loss harvest.

Example 3: Edward anticipates making approximately $100,000 in 2021 in wages from his employer. If Edward can identify a stock/bond/mutual-fund/ETF with a built-in loss, he can sell the security and reduce his taxable income up to the lesser of the loss or $3,000 in 2021. If Edward owns the XYZ mutual fund with a historic basis of $5,000 and a current value of $2,000, he can sell it before year-end and reduce his taxable ordinary income from approximately $100,000 to approximately $97,000. The capital loss deduction is one taken on the first page of the Form 1040 and is not an “itemized deduction.” Thus, Edward gets the deduction regardless of whether he itemizes his deductions.

Note that Edward is limited in his ability to deduct capital losses in any one taxable year to $3,000. Let’s slightly revise the previous example.

Example 3A: The facts are the same as in Example 3, except the the stock Edward sells has a basis of $10,000. Thus, Edward’s current year capital loss is $8,000 ($10,000 basis less $2,000 sales price) instead of $3,000. However, Edward still can only deduct $3,000 because of the limit on taking capital losses against ordinary income. Thus, Edward’s 2021 taxable income is still approximately $97,000.

Edward can carry forward the excess unused capital loss ($5,000, which is the $8,000 actual loss less the $3,000 used loss) into future tax years. Thus, in 2022, he can offset capital gains and up to $3,000 of ordinary income by the $5,000 capital loss carried forward. If Edward has no capital gains or losses in 2022, he can deduct $3,000 of the $5,000 against his 2022 ordinary income, and then carryforward a $2,000 capital loss into 2023. Edward carries forward the capital loss until it is fully used.

Wash Sales

Tax loss harvesting sounds great, right? But with tax, there’s almost always a catch, and one exists here. The so-called “wash sale” rules.

They are best understood by understanding the concern they address. Say in our first Example Mark sells his 100 shares of Kramerica stock on December 15th to trigger the capital loss. Then on December 16th Mark buys 100 shares of Kramerica stock. Absent the wash sale rules, Mark has had no change in his overall economic position (he still owns 100 shares of Kramerica) yet he’s realized a $3,000 capital loss for tax purposes.

The wash sale rules step in to prevent this sort of gamesmanship. They disallow any loss on the sale of securities when the taxpayer buys the same or similar securities within the period starting 30 days before the loss sale and going through 30 days after the loss sale. The rule applies broadly. It applies to similar securities — for example, selling Vanguard’s S&P 500 index mutual fund at a loss and buying Fidelity’s S&P 500 index mutual fund. It applies to purchases of the same or similar securities by the taxpayer, the taxpayer’s spouse, and by entities controlled by the taxpayer and the taxpayer’s spouse. It can also potentially apply to purchases inside retirement accounts. The wash sale rule also bites to the extent of shares purchased through a dividend reinvestment program where the reinvestment occurs within the 61 day window described above.

Conclusion

Tax loss harvesting provides taxpayers a great opportunity to offset capital gains and possibly up to $3,000 of ordinary income. To work effectively for 2021, taxpayers must sell loss securities by December 31st and must be careful to avoid repurchasing the same or similar securities in a manner that triggers the wash sale rules and disallows the capital loss.

  1. Is the wash period 30 calendar days or business days? I’m in the position of having a tax loss harvest (actually I had set a hard stop loss order, and it was triggered)…but may want to buy back the stock.

    1. Cathleen – great question! The 30 days is 30 calendar days, so weekends and holidays count just like regular weekdays.

  2. Is there a minimum length of time you need to own the stock before you can sell it to qualify for a capital loss?

    1. Absent unusual circumstances (such as being a dealer of stock) all stock sales at a loss qualify for capital loss treatment. However, if you have owned the stock for a year or less, it will be a short-term capital loss. The significance is that short-term capital losses first offset short-term capital gains. Then if there is a net short-term capital gain, the net short-term capital gain will be taxed as ordinary income. If after the first netting there is a net short-term capital loss, that is used to first offset any net long-term capital gains, and if there is any remaining, it will offset ordinary income, but only up to $3,000 per tax return. Complicated, I know – hope that helps!
