Among the copious data advisors require from clients, tax returns are mission critical.
The documents are necessary to better design the plan, because taxes are fees, too, making tax alpha a priority. (While I’m still a licensed CPA, you don’t have to be one to find savings from tax returns.) The alpha from taxes is paramount because building tax-efficient portfolios and strategies is often a better way to add alpha than trying to beat the market. Here are six investing insights that can benefit clients:
Look to see if clients have a capital loss carryforward. With markets nearing all-time highs again, you’d think this would be fairly rare. It’s not, and clients regularly have huge tax-loss carryforwards. This provides two key insights. First, determine where the loss came from to shed light on possible poor behavior, such as panicking and selling during past market plunges. Many have said they buy in down markets only to have the tax return show otherwise. Understanding where the losses came from is critical in determining how much risk a client should take.
The second insight is that a loss carryforward opens possibilities to exit investments with high fees or those that are otherwise undesirable, such as expensive funds, or concentrated positions, while paying no taxes. (I jokingly tell the client: “I’m sorry for your loss, but let’s make the best of it.”) Estimate how much in the way of gains can be recognized without paying any federal income tax. That’s not to say that you should use all of it up because that loss carryforward has value for future years. Any unrealized losses can also be sold and used to offset gains or add to the tax-loss carryforward.
Understand Recognized Capital Gains and Dividends
Is the client recognizing capital gains and showing high dividend income? Sometimes this shows frequent trading but, more often than not, it’s due to being in tax-inefficient vehicles. When a mutual fund trades and recognizes a gain, it pushes out that gain to the client via a 1099. ETFs can almost always eliminate passing through gains via the creation and redemption process they use.
Also look at dividend income. That’s because total return is far more important than chasing dividends. Not only are they tax-inefficient (even qualified dividends) but they have also badly underperformed.
Manage to Marginal Tax Rates. Investment decisions have tax consequences. So, to the extent we can manage the tax brackets below, we add value. For example, we can manage how much of a Roth conversion the client should do. Or perhaps a retired client might be in the 0% federal long-term capital gains rate and can recognize gains with no federal taxes. (I typically recommend always using up the 10% and 12% marginal bracket and frequently using up all of the 24% bracket.) You can also assess how much benefit the client is getting from owning municipal bonds. And don’t forget state income taxes if the client is domiciled in a state that has income taxes.
Understanding Marginal Tax Rates on Capital Gains Is Also Critical. How much long-term gain can be recognized before the client hits the federal 20% marginal tax? Even if they are in the 15% marginal rate, are they being hit with the 3.8% net investment income tax (income over $200,000 single and $250,000 married filing jointly)? Often, the client can spread the gain over a couple of years.
Assess the Benefit of Debt. I’ve noted for decades that a mortgage is the inverse of a bond. If the client has enough liquidity, it rarely makes sense to borrow money at a higher after-tax rate than they lend it out at. Look at the clients’ itemized deductions in schedule A and compare the after-tax cost of the debt to the after-tax interest income they are receiving on a high-quality bond in their taxable account. Paying off the debt is typically what I call “low hanging fruit” in that it provides a risk free and tax-advantaged higher return than bonds.
Make Charitable Contributions the Right Way
Don’t tell clients how much they should be donating to charity or which charities to donate to, but advise clients that they can do this in a tax-efficient way and still provide the same benefit to the charity. If you see they have made large cash contributions, explore making large lumpy donations of appreciated security to a low-cost Donor Advised Fund and doing so every few years rather than annually. The appreciated security can then be sold in the DAF without taxable consequences. Then, over the next several years, the client can have the fund give to that same charity.
This gives them both tax savings from avoiding taxes on those unrealized gains and a much bigger tax-benefit from the gift itself. And you get a bonus for the client if they have such an underperforming investment with a big gain.
If the client is over 70.5 years old, a qualified charitable distribution is even better. A QCD allows those individuals to donate up to $111,000 total to one or more charities directly from a taxable IRA instead of taking their required minimum distributions. This not only reduces taxable income, it reduces the client’s modified adjusted gross income, which helps with other taxes such as the Medicare premiums from the Income-Related Monthly Adjustment Amount.
Find Investment Deductions They Haven’t Been Taking. The biggest miss I see is that the client’s CPA typically hasn’t taken a state deduction from interest income from US government obligations (such as Treasury bills, notes and bonds). They are exempt for state and local income tax. Most (but not all states) allow a deduction from a fund that has some government interest. For example, the Vanguard Total Bond Market ETF (BND) had 44.06% of its income from US government obligations.
Another example of tax alpha is using a health savings account like a Roth. I often tell clients to max out their HSA contributions but pay for medical costs from taxable money. They can then keep the receipts and reimburse themselves tax-free decades later.
These are only some of the insights one can gain from a tax return. Remember, finding that tax-alpha can actually be better than trying to beat the market.

Opening Takes

"Tax-efficient portfolio construction is a legitimate fee-justifier for advisors but is not a market-timing or security-selection edge; it's a cost-reduction play that benefits individual clients without signaling broader market opportunity."

This article is a how-to guide for financial advisors, not investment analysis. The real insight: tax optimization is being positioned as alpha generation, but this conflates two different things. Tax efficiency is table stakes for professional advisors—it's not a market edge, it's a fee justification. The article correctly identifies genuine inefficiencies (mutual fund turnover, dividend chasing, debt management), but these are behavioral/structural problems, not forward-looking market signals. The strongest tactical point is the DAF arbitrage for appreciated securities and the HSA reimbursement float, but these are niche strategies affecting portfolio margins, not sector rotation or macro positioning.

Devil's Advocate

If tax optimization were truly as valuable as claimed, why haven't passive index funds and robo-advisors already captured most of this alpha? The article assumes advisors aren't already doing this—but the real question is whether tax alpha still exists at scale, or if it's been competed away.

"Tax-efficient structural shifts, such as moving from mutual funds to ETFs and utilizing HSAs for long-term investing, provide more predictable alpha than active stock picking."

The article correctly identifies 'tax alpha' as a reliable driver of net returns, particularly through the use of ETFs over mutual funds to avoid capital gains distributions. I am particularly focused on the 'mortgage as the inverse of a bond' argument; with the 10-year Treasury yielding around 4.2% and new mortgage rates significantly higher, paying down debt is a guaranteed risk-free return that beats most fixed-income allocations. However, the strategy of using HSAs as long-term Roth-style vehicles is the real sleeper hit here, as it provides a triple-tax advantage that outperforms traditional brokerage accounts by 20-30% over a 20-year horizon due to tax-free compounding.

Devil's Advocate

Aggressively harvesting losses and paying down low-interest legacy debt (3-4%) ignores the opportunity cost of being out of a momentum-driven equity market that has historically averaged 10% annual returns. Furthermore, over-optimizing for current tax brackets can lead to 'tax traps' where massive RMDs in later years push retirees into higher brackets than they anticipated.

"Tax returns reveal low-hanging alpha like loss carryforwards and ETF swaps that can add 1%+ annually without market risk."

This article rightly elevates tax returns as a goldmine for advisors, spotlighting capital loss carryforwards (often $50k+ even in bull markets) to harvest tax-free gains from high-fee funds, and pushing ETFs over mutual funds to curb embedded gains—Vanguard's BND (44% gov't income) exemplifies state-tax deductions missed by CPAs. Debt payoff math is spot-on: 4% after-tax mortgage vs. 3% taxable bond yield screams arbitrage. QCDs ($105k limit in 2024, not $111k) and DAFs amplify charity alpha. Yet, it underplays execution: client resistance to selling winners, CPA pushback, and TCJA sunsets post-2025 could erode brackets. Tax alpha reliably adds 0.5-1.5% annually vs. elusive market outperformance.

Devil's Advocate

Tax strategies demand precise coordination with CPAs and constant law updates; botched advice risks IRS audits, penalties, or suboptimal portfolios chasing tax efficiency over returns.

"HSA tax arbitrage only works if clients actually leave money untouched for decades—a behavioral assumption the article glosses over."

Gemini's 20-30% HSA outperformance claim needs scrutiny. That assumes max contributions ($4,150 individual, 2024), tax-free growth for 20+ years, and never touching it pre-65. Reality: most HSA holders spend it annually on medical bills, gutting the compounding thesis. Grok's 0.5-1.5% annual tax alpha is more defensible—but that's portfolio drag reduction, not alpha generation. Claude's core point stands: this is fee justification, not market edge.

"Tax-loss harvesting can lead to portfolio paralysis and ignores the looming 2025 TCJA sunset risk."

Grok and Gemini are ignoring the 'Tax-Efficiency Trap.' By prioritizing tax-loss harvesting and debt payoff to secure that 1.5% 'alpha,' you risk creating a portfolio of 'zombie' holdings—low-basis assets you can never sell without a massive hit. Furthermore, Grok’s mention of the TCJA sunset is the real macro risk; if brackets jump in 2026, accelerating income now is the play, yet the article and panel focus almost exclusively on deferral.

"Paying down a mortgage isn't an automatic risk-free win; you must model after-tax cost, liquidity/option value, and portfolio trade-offs probabilistically."

Treating a mortgage as the inverse of a bond and calling prepayment a 'guaranteed' risk-free return is oversimplified: mortgage interest is after-tax (sometimes deductible), principal is illiquid, and prepayment destroys liquidity and optionality valuable in downturns. Advisors should compare the after-tax cost-of-debt to expected, risk-adjusted portfolio returns using probabilistic cash‑flow and refinance scenarios—not a simple rate-vs-yield rule.

"Mortgage prepayments secure superior after-tax returns with HELOC liquidity, especially pre-TCJA sunset."

ChatGPT's liquidity critique of mortgage prepayments misses that extra principal builds home equity, tappable via HELOCs (currently 8-9%, but refinancable), while delivering 5-7% after-tax risk-free returns on outstanding 6%+ mortgages ( Freddie Mac avg $400k balance). This trumps 4.2% T-bills post-tax for 70% of homeowners. TCJA deduction phaseout post-2025 amplifies the urgency—no simple rule, but math favors payoff over bonds.
