Once you've sold off those assets, certified financial planner Cody Garrett, who runs Measure Twice Planners in Houston, advises that you can 'refresh the page and repurchase the same security right away.' Garrett is also the co-author of the fresh-off-the-press book 'Tax Planning To and Through Early Retirement' (available at www.measuretwicemoney.com/book).
However, there's a catch known as the wash sale rule (detailed in this CNBC article: https://www.cnbc.com/2024/11/15/tax-loss-harvesting-etfs.html). According to the IRS, this rule blocks you from claiming a tax break on losses harvested by buying 'substantially identical' assets within 30 days before or after the sale. But, importantly, Garrett points out that this restriction doesn't kick in when you're dealing with profitable assets – you're free to buy and sell without that hassle.
That said, reaping those gains isn't always straightforward, as Garrett warns. Generating extra income could set off a chain reaction of other financial repercussions that you might not anticipate.
So, what exactly do investors need to grasp? Let's break it down step by step to make it crystal clear, even if you're just starting out in the world of investing.
First, how does that 0% capital gains bracket actually function? For investments you've held longer than a year, any profits usually qualify as long-term capital gains, taxed at rates of 0%, 15%, or 20%, based on your overall taxable income. Some folks in higher income brackets might also face an extra 3.8% net investment income tax (explained here: https://www.cnbc.com/2023/07/05/how-to-avoid-the-net-investment-income-tax-for-2023.html).
Looking ahead to 2025, the income threshold for that zero-percent bracket stands at $48,350 for single filers or a combined $96,700 for married couples filing jointly. To calculate your taxable income, you take your adjusted gross income (learn more from the IRS at https://www.irs.gov/filing/adjusted-gross-income) and subtract the larger of your standard deduction or your itemized deductions.
Remember, the standard deduction for 2025 is set at $15,750 for singles and $31,500 for those married filing jointly. For instance, picture a married couple earning $120,000 – after deducting that $31,500, their taxable income could comfortably stay under $96,700, keeping them in the clear.
And for our seasoned citizens, there are extra perks in the form of additional standard deductions, including a brand-new $6,000 'senior bonus' (covered in this piece: https://www.cnbc.com/2025/12/10/social-security-tax-bills.html), thanks to President Donald Trump's 'big beautiful bill' (more on that at https://www.cnbc.com/2025/07/03/trump-big-beautiful-bill-tax-changes.html).
But watch out – selling those investments might unexpectedly push your taxable income over the edge of the 0% threshold, turning your tax-free profits into taxable ones.
On top of that, end-of-year distributions from mutual funds (check out this CNBC insight: https://www.cnbc.com/2025/11/06/mutual-fund-capital-gains-payouts.html) or dividends from exchange-traded funds could inflate your taxable income further. As CFP Michael DeMassa from Forza Wealth Management in Sarasota, Florida, puts it, 'A lot of people have ETF or mutual fund dividends reinvested. They've never cashed them in, but they still pop up on their tax returns, adding to the pile.'
So, what should you consider before jumping into harvesting those gains? If your taxable income sits snugly within the 0% bracket, selling assets without owing taxes might be totally feasible.
Yet, Garrett from Measure Twice Planners cautions that ramping up your income can trigger other unforeseen effects. Take older Americans, for example – they might accidentally hike up taxes on their Social Security benefits (details at https://www.cnbc.com/2025/12/10/social-security-tax-bills.html) without realizing it. Or, if your family is pursuing college aid, this could complicate things when submitting the Free Application for Federal Student Aid (FAFSA, explored here: https://www.cnbc.com/2025/09/25/education-department-opens-fafsa-ahead-of-schedule.html).
Another potential snag is qualifying for subsidies under the Affordable Care Act marketplace health insurance (more on this at https://www.cnbc.com/2025/07/22/aca-health-insurance-trump-taxes.html), which help lower those monthly premium costs. In 2025, over 22 million people – about 92% of those enrolled (per KFF, a health policy think tank: https://www.kff.org/affordable-care-act/state-indicator/marketplace-plan-selections-by-financial-assistance-status-2/?currentTimeframe=0&sortModel=%7B%22colId%22:%22Location%22,%22sort%22:%22asc%22%7D) – rely on these subsidies to make coverage affordable.
Before you make any moves, DeMassa emphasizes from Forza Wealth Management, 'you need to know the tax impact' because 'there are a lot of moving parts.' It's like assembling a puzzle – one wrong piece, and the whole picture changes.
Now, here's where the debate really heats up: Some argue that these tax rules unfairly favor savvy investors, potentially widening the wealth gap. Others say they're a smart incentive for long-term investing. What do you think – is maximizing tax brackets a savvy move for everyone, or does it just add another layer of complexity to an already tricky system? Do you agree with the wash sale rule's logic, or should it be overhauled? Share your opinions in the comments – let's start a conversation!
