In the pursuit of smart tax planning, nothing is more frustrating than discovering that a timely switch costs you more than it saves. You made a loss-harvesting trade, sold a dog of a stock, and depended on the deduction, only to discover that the IRS disallowed it because of a technicality you were unaware of.
This is what happens to those investors who fall into the wash sale rule, an overly complex and generally unnoticeable rule, which is able to bring serious impediments to the otherwise advanced tax plans.
If you’re a wealthy investor dedicated to building tax-efficient wealth, it’s not an option to be cognizant of how to avoid wash sale rules and avoid impact. It’s required.
So what is this rule, and why does it come as a shock even to the most seasoned investors?
What Exactly Is the Wash Sale Rule, and Why Does It Matter So Much?
The IRS wash sale rule does not permit investors to manufacture tax losses. It disallows deducting the loss on the sale of a security or stock if you purchase the same, or a “substantially identical,” investment within a 61-day window surrounding the sale.
In particular, the rule applies if you purchase exactly the same security (or one that is highly similar) within 30 days prior to or following the sale, establishing a 61-day period of prohibition.
So, how does the wash sale work? Let’s say you sell a share of a tech stock for a loss of $10,000 on December 15. If you purchase the same stock or a mutual fund or option that closely follows it, between November 15 and January 14, you won’t be able to claim that loss on your tax return.
The prohibited loss isn’t lost forever. It’s credited to the cost basis of the replaced security. But this postpones the tax benefit, which can be a huge issue if what you’re doing relies on quick offsets to capital gains.
According to the Electronic Code of Federal Regulations, Title 26, §1.1091, the stock wash sale rules, securities, mutual funds, and options, with some exceptions. Even “substantially identical” investments can lead to a violation—a carefully ambiguous term that has caught many investors off guard and infuriated them at tax time.
But what is the real cost of breaking the rule? That is where it becomes dangerous.
How the Wash Sale Rule Can Disrupt Your Tax Strategy
If you handle tax-loss harvesting correctly, it can really lower your tax bill. But the wash sale rule can sneakily undo those savings if you’re not paying attention.
This is what occurs when a wash sale is executed:
- Loss of capital is prohibited this year
- The amount lost is added to the cost basis of the re-purchased security
- The holding period of the new holding reverts, which may affect long-term capital gains treatment
It creates two problems:
- You forego immediate relief that may have reduced taxable gains in the same year.
- You make your future tax returns more complicated by including a cost-basis adjustment that needs to be replicated exactly.
For high-net-worth investors, the ramifications are even more dire. A misplaced $50,000 loss can engender an unexpected $10,000 – $20,000 tax expense, depending on your actual rate of capital gains taxation. And if these mistakes accumulate across several accounts or transactions, the tax expense can compound.
So who’s likely to get caught in this tax trap? The answer may surprise you.
Who Is Most at Risk of Triggering the Wash Sale Rule?
The wash sale rule unfairly penalizes active investors who are most involved in portfolio optimization. Ironically, the more active and strategic you are, the more likely you are to break it.
Here’s who needs to be most cautious:
- Active traders: Any time you’re trading equities on a frequent basis especially within short time frames, you’re constantly in the wash sale 61-day rule risk zone.
- Automated tax-loss harvesting platforms: Robo-advisors will typically automate loss harvesting but won’t necessarily review all positions on all accounts. What’s the end result? An illusion of security.
- Crypto traders: Although the wash sale rule is not yet applicable to crypto, the IRS has indicated that this loophole could be closed in future legislation. It is best to prepare on the assumption that crypto regulations will change.
- Retirement account investors: The most prevalent missed trap is the wash sale IRA trap. When you sell a security in your taxable account for a loss and then buy the same security within thirty days in your IRA account, the loss is disallowed, not merely delayed.
The SEC’s Investor.gov glossary on wash sales informs investors about how trades are executed between accounts and platforms and how they may affect one another. It should be noted that the majority of the platforms won’t notify you if a cross-account wash sale is executed.
So, how do you protect yourself without forgoing opportunities for tax efficiency? It’s all about more intelligent implementation.
How to Avoid Wash Sale Without Losing Your Strategy
Not following the wash sale rule is not a stop loss harvesting disqualification—it just means you must do so through a system that considers timing, substitutions, and proper coordination.
The following are essential means of avoiding violations:
- Wait for a minimum of 31 days before you purchase the same security again. This is the easiest way out. Invest the proceeds for the period in a money market fund or short-term Treasury.
- Replace the security with a substitute, but not the same type of investment. For example, instead of selling and purchasing a specific tech stock, exchange a diversified tech sector ETF for other underlying securities.
- Coordinate all accounts. Wash sales may be created in any account of the same taxpayer ID, such as IRAs, trusts, and joint accounts.
- Use tax-smart software or work with a fiduciary advisor. A fiduciary wealth strategist can track tax lots, trades, and timing between accounts precisely, allowing you to harvest losses while staying IRS compliant.
- Stocks or securities of different corporations are not considered substantially identical. Preferred stock and common stock of the same company are generally not considered substantially identical, but there are exceptions, such as convertibility or similar voting rights.
- Utilize the “double up” strategy: If you want to maintain your position in a specific stock, you could purchase additional shares at the current price and then wait at least 31 days before selling the original shares that were at a loss. This allows you to claim the loss while still holding the desired investment amount.
However, even if you do play by the numbers, the rule itself is not necessarily cut and dried—especially in the liquid world of crypto, ETFs, and hybrid portfolios, in those grey areas where experience trumps theory. Let’s take a gander at a few of them.
Gray Areas and Exceptions You Need to Know
The wash sale rule is somehow non-applicable or unclear in some instances. But that doesn’t necessarily mean they are safe to disregard.
- Crypto: At present, cryptocurrencies are “property” and not securities according to the IRS. That is to say, the wash sale rule on crypto does not apply—yet. Legislation in progress could reverse that, and astute investors would do well to look ahead.
- Mutual funds and options: Swapping one mutual fund for another with identical holdings can still raise the IRS’s eyebrows if they’re “substantially identical.” Options on the same underlying security are on the target list.
- IRAs: Selling a stock from your tax account and buying it in your Roth IRA or traditional IRA is not an exception. It’s a permanent loss disallowance—one of the limited cases in which the IRS will not permit you to recover.
So, how do you weather this uncertainty most effectively? It starts with creating strategies that are planned out across all your accounts, and it requires collaboration at a high level.
