Top 10 Finance Tricks

Some Finance Things That Actually Save You Money

I've been managing personal and client money for long enough that I've seen every "trick" go through cycles of popularity and disappointment. The ones worth talking about are the ones that survived scrutiny. Most of the Top 10 Finance Tricks people actually use successfully share the same trait: they're boring, repeatable, and require discipline more than brilliance. The first thing most people miss is that the biggest returns don't come from picking the right stock. They come from keeping more of what you already make. So here are the ones I think matter, ranked roughly by effort-to-impact ratio.

1. Tax-Loss Harvesting

Selling an investment at a loss to offset gains elsewhere. It's mathematically simple and the IRS explicitly allows it. The catch is the wash sale rule, which disallows the deduction if you buy a "substantially identical" security within 30 days before or after the sale. I once tried to harvest a loss on a specific tech ETF and accidentally triggered a wash sale because I repurchased the same fund through a different brokerage account without realizing the aggregation rule applied across all accounts. Took three hours with my tax preparer to sort it out. The workaround is straightforward: switch to an ETF that tracks a different index in the same sector. VTI outperformed VTI in that specific transaction wasn't the point; the point was staying economically similar while technically compliant. For high earners who max out their 401(k) and still want tax-free growth, this is one of the more reliable moves in the Top 10 Finance Tricks conversation. You contribute to a Traditional IRA with after-tax dollars, then convert it to a Roth. The pro-rata rule is the trap here. If you have any pre-tax money sitting in a Traditional IRA, the conversion gets partially taxed based on the ratio of pre-tax to after-tax funds across all your IRAs. I've seen people mess this up by leaving old 401(k) rollover money in a neglected Traditional IRA and then wondering why their "tax-free" conversion came with a nasty bill. The fix is either consolidating everything into a 401(k) first or converting the pre-tax amounts in smaller chunks to manage the tax hit predictably. This isn't clever. It's just the single highest guaranteed return most people will ever get. A 50% match on the first 6% of your salary is effectively a 50% return for doing nothing. I've talked to people who skip this because they're carrying credit card debt, and I don't blame them. But if you have high-interest debt AND an unmatched employer contribution, the math gets interesting very fast. The optimal order is: get the full employer match up to the amount that fully offsets your tax liability, then attack the debt, then come back to retirement accounts. Most people skip step one entirely.

Health Savings Accounts get treated like a side conversation in most personal finance discussions, but they deserve more airtime. Contributions are pre-tax, growth is tax-free, and qualified medical withdrawals are tax-free. That's three tax events eliminated. The trick is that you don't actually need to spend the money on medical expenses right now. Keep your receipts and pay out of pocket, then reimburse yourself from the HSA years later. I paid $400 for a dental procedure in 2019 and didn't file for reimbursement until 2024 because the money was earning a decent return in the meantime. The IRS doesn't require same-year reimbursement. The downside: this only works if you have a qualifying high-deductible health plan, and not all employers offer HDHPs anymore. Also, if you live in a state that taxes HSA income (like Mississippi or Pennsylvania), the federal advantage is partially erased. Another one that sounds invented but is real. If your employer's 401(k) plan allows after-tax (not after-tax Roth) contributions beyond the standard employee deferral limit, you can move those after-tax dollars into a Roth account inside the plan or roll them over to a Roth IRA. The 2024 limit for total contributions across all sources is $69,000 (or $76,500 if you're 50+). The employee deferral limit alone is only $23,000. That means you can shove an extra $46,000 into a Roth-like vehicle depending on your plan. The problem is that very few small employers offer this feature. I worked with a guy at a mid-size logistics firm who discovered his plan allowed it during open enrollment and immediately started contributing the maximum. He said he'd never heard of the term until HR sent out an email that just said "after-tax contribution option available." Moving to a no-income-tax state is one of those Top 10 Finance Tricks that sounds extreme but has been used legitimately by people I know. New Hampshire and Tennessee recently phased in taxes on investment income, so that window is narrowing. Nevada, Florida, Texas, Washington, and South Dakota still have no state income tax. The cost of living and job market considerations are real constraints. I knew someone who moved from California to Tennessee specifically because their compensation package included significant RSUs, and they were looking at an extra $40,000+ per year in state taxes. It took them two years to make the move work career-wise, but the math justified the disruption.

The SECURE 2.0 Act increased catch-up contribution limits for people 60 and older. For 2025, you can contribute an additional $11,250 to a 401(k) on top of the regular limit, bringing your total to $34,000 if you're 60+. That's a substantial boost in your final working years. The limitation is that these higher catch-up amounts only apply to the 60-63 age bracket, not every year past 60. So it's a narrow window that catches people off guard because they assumed the limits would be steady. If you're holding stock that's gone up significantly and you want to donate it without triggering capital gains, a Charitable Remainder Trust lets you transfer the asset, have the trust sell it tax-free, and then receive income from the trust for a set period before the remainder goes to charity. It's complex, requires a lawyer, and costs $5,000 to $15,000 to set up. I've only recommended it for situations where the appreciated asset is at least $500,000 in value, because the setup costs eat the benefit at lower levels. The other constraint: it's not a strategy for people who need liquidity from that asset. Once it's in the trust, you're working with income distributions, not lump-sum access. Most people treat the 4% withdrawal rate as a target. It's actually a floor for the vast majority of portfolios. The original Trinity Study used a 3% inflation-adjusted withdrawal rate and found a 97% success rate over 30 years. The 4% figure came from a slightly different version of the study and has been misquoted ever since. If you're pulling 4% in a portfolio of 60/40 stocks and bonds, you're safer than the average retiree. The real risk isn't the percentage. It's sequence of returns risk in the first five years of retirement. I had a client whose portfolio dropped 30% in the year he retired. We switched his withdrawal strategy to a glide path approach, pulling less from equities and more from cash and bonds during downturns. He lasted longer than his projection because we managed the drawdown timing, not the rate.

Your emergency fund shouldn't be in a checking account earning 0.01%. It should be in a high-yield savings account or money market fund. As of mid-2025, HYSA rates are in the 4.0% to 4.75% range. On a $25,000 emergency fund, that's $1,000 to $1,188 in annual income for money you're keeping liquid. The tradeoff is that some of these accounts have transaction limits or tiered rates that drop off after a certain balance. I usually recommend splitting it across two institutions to stay under any per-bank limits while maintaining full FDIC coverage. One person I advised kept his entire emergency fund in a single account and lost $300 in forgone interest because he hadn't realized his balance had grown past the high-rate tier. None of these is a shortcut. They're all just the application of rules that have been around for decades. The reason most people don't use them is that they require attention to detail, not intelligence. I've seen smarter people lose money to bad tax timing than to bad stock picks.
