When you get your tax return from your accountant, you probably do what 99% of people do. You flip right to the end and you're looking for one of two numbers. How much do I owe? Or how big is my refund?
But for millionaires, getting their tax return back is when the real work starts. And I know. I've seen both of these scenarios for more than 30 years. You see, your tax return is a receipt for last year's financial plan. And millionaires see their tax return as a diagnostic report that can turn into a road map for the next year.
They treat it like a doctor reads an MRI. They aren't just looking for a thumbs up or a thumbs down. They're hunting for clues. They're looking for costly mistakes, hidden financial risks, and huge opportunities that even their accountant might have missed. So in this video, I'm going to walk you through the five critical areas that millionaires scrutinize on their tax returns to protect and build their wealth.
Now the first place the wealthy look, it isn't the refund or the amount they owe. It's line 11 on your Form 1040, your adjusted gross income or AGI. This is probably the most important number on the tax return. It's the master key that unlocks or locks almost everything else. Your AGI is your gross income minus a few specific above-the-line deductions like contributions to your IRA or an HSA.
Talking about the adjusted gross income or that AGI number, it reminds me of a recent tax return that I was scanning for one of our clients. And this one was for the new year and we're working on their planning for the coming tax return. So they were thinking about everything else except the AGI. And we started looking at it and because they were working on some Roth conversions, they weren't thinking about what that could do.
But that AGI number, it tells it all and when we started applying the conversion for them to show them the outcome, they realized it was going to do a lot of things that they weren't expecting. And those things were really ugly and they're going to cost them a lot more in tax and some hidden costs that are associated with things like Medicare and their Part B and their Part D premiums. We'll talk more about that later in the show.
This is the kind of thing that shocks retirees. They sell a piece of property or take a larger than normal IRA distribution and a couple years later they wonder why their Medicare premiums jumped. They don't connect it back to that tax return two years ago. But the tax return is exactly where that story started.
Most people think, "Okay, that's just my income before my big deductions." But the wealthy, they know this number is a tripwire. Why is it so important? Because your AGI determines your eligibility for a huge range of credits and deductions. And more importantly, it dictates whether you get hit by some of the more stealth-like taxes that high-income earners they're not always thinking about.
For example, once your AGI crosses certain thresholds, your investment income could trigger a 3.8% net investment income tax on top of your regular capital gains taxes. A high MAGI or MAGI, that can also trigger something called IRMAA, the income-related monthly adjustment amount. And this is a surcharge that can dramatically increase your Medicare Part B and Part D premiums.
And the important thing here is that IRMAA is based on your tax return from 2 years ago. So, a high income event in say 2026 like selling some property or making a large IRA distribution, that could come back to bite you with a massive Medicare Part B and D cost in 2028. This is shocking to a lot of people when it happens because they don't think of tax return from 2 years ago.
Millionaires, they obsess over the AGI because they know it's not just an income figure. It's more like a control panel for the entire financial picture. They are more likely to ask, "What did this number expose me to this year? And what can I do next year to manage it?" They plan their income, their retirement contributions, their investment sales all with an eye on keeping that AGI below those critical thresholds.
All right. The second thing a millionaire checks is the refund. If they're getting a massive refund, they're not celebrating. They see that as a sign of poor planning. It doesn't always mean something is wrong, but it does mean something should be reviewed and probably adjusted. When you're getting a large refund, you're probably putting way too much in the government's pocket before it's time.
Think about it. A tax refund, that is not free money from our government. It's your money being returned to you after you loaned it to the government for 16, 17, 18 months interest free. If you got a $6,000 refund, that means you overpaid your taxes by $500 every month. That's $500 a month that could have been covering something else like paying down high interest debt. Instead, it was just sitting in the Treasury's account doing nothing for you.
The goal of a well-calibrated financial plan is to come as close to zero as possible. Owing a little, that's fine. Getting a little refund, that's okay. But a huge refund signals that your withholding is not calibrated. For an employee, this means adjusting your W-4. For a business owner or someone with investment income, it might mean you've got to reevaluate those quarterly estimated tax payments.
That money could have been working somewhere else all year. So, if they see a big refund, the first question is, "How do we fix our withholding or estimated payment so this money is put to work for us during the year, not after?"
Next, a millionaire will turn to Schedule D, and that's the form where you report all of your capital gains and losses. An amateur looks at this, and they'll ask, "How much gain did I have, and how much tax will I owe?" And that's the first level question. But the millionaire, they'll ask a second, more important question. "What did that gain cause?"
This is the ripple effect that we talked about with AGI. Realizing a big capital gain, it doesn't just create a tax bill on the gain by itself. It pours more income into your AGI bucket. And that's why I do not just look at the gain by itself. I want to know what else that gain touched. Did it trigger another tax? Did it affect Medicare down the road? Did it make Social Security more taxable? Did it push the client into a worse situation than they were expecting?
And as we saw with the higher AGI, it can push you into a higher tax bracket, and that can trigger that net investment income tax of an additional 3.8%. Potentially, increase your Medicare premiums, and maybe more. It can also cause your Social Security benefits, if you're receiving them, to become more taxable.
So, what are high net worth individuals looking for on that return? They're looking for the story behind the numbers, not just the numbers. Did they sell stock and why? Was it a planned rebalancing or did they panic and sell something? And more importantly, was it tax efficient?
For instance, if they sold shares of a stock, did their broker sell the right tax lots? Selling shares that you bought 10 years ago at a lower price, that creates a much bigger gain potentially than selling shares you bought say just two years ago at a higher price. And this is called tax lot matching and it's a fundamental strategy, but it's also one that gets missed.
Now, they're also looking for other missed opportunities. Does Schedule D show a large gain, but no corresponding losses? To me, huge red flag. It's a red flag because we're missing something called tax loss harvesting. Tax loss harvesting, basically, we're going to sell losing investments to offset the gains from your winners.
Now, a properly managed portfolio should be harvesting for losses throughout the year to minimize the tax impact, but it's not always done. Seeing a big unmanaged gain on a tax return is a sign that your investment strategy and the tax strategy are probably not coordinated.

Now, let's get into one of the most common and most costly mistakes that I see on tax returns. This next one is where fortunes can be lost just in the paperwork. A millionaire will meticulously scan lines 4A and 4B of their 1040. Now, what is 4A and 4B? Well, these report your IRA distributions. To the average person, a number here just means, oh well, I took money out of my IRA. To a more sophisticated investor, this is a potential minefield of errors.
The most common and devastating error that I see, it relates to the backdoor Roth IRA. Easy to miss here. This is a strategy used by a lot of high income earners. You might be using it, and it's done to fund the Roth IRA. In simple terms, you contribute money to your traditional IRA, which is perfectly legal even if you make too much money, and then you immediately convert that to a Roth. And since you've already paid tax on it, in theory, this should be a tax-free conversion.
So, I saw this recently. I was reviewing a return for a client in their 40s, and I saw a taxable IRA distribution. So, I walked into the advisor's office here at our firm. He services that client. And I asked, "Why did this client have a taxable IRA distribution?" And he said, "Well, they didn't." And I said, "Well, according to the tax return, they did."
What actually happened was a backdoor Roth. The after-tax contribution, it went into the IRA, then moved into their Roth. Perfect. In the short window before it converted, there was about a $153 growth. That small amount would have been taxable, but the return appeared to treat the whole transaction as taxable. That is the difference between paying tax on a small amount of growth and paying tax on the entire transaction.
The CPA had the form, the 1099, the advisor had the contacts, the client had no idea there was a problem. And that is where mistakes happen. A 1099 tells you money moved, but it doesn't always tell you why it moved. What is taxable? Was it a taxable withdrawal? A Roth conversion? A backdoor Roth? A rollover? A qualified charitable distribution? Those are not the same thing.
Here's the problem. Your financial institution, yes, they send the IRS a form, a 1099-R, that just says money moved out of a traditional IRA. It doesn't tell the story of why it moved necessarily unless someone knows how to read the other codes. It's up to your tax preparer to correctly report this story on the 8606. This form is what tells the IRS, "Hey, this wasn't a taxable withdrawal. This was a conversion of after-tax money."
If this form is missed or filed wrong or that 4A and 4B gets the wrong information, the IRS assumes the entire conversion is a taxable distribution. And I just saw clients have to pay tax on the full conversion amount when it should have been tax-free with the exception of that $153 that I mentioned. They essentially paid tax twice on the same money. And if you don't catch this error within 3 years, that money is gone forever. Fortunately for our clients, we caught the mistake, talked to their CPA, got it fixed, all is good.
So, what would a millionaire do when they're looking at their return? They would be asking, "Does this return correctly reflect the intent of my retirement moves? Did a tax-free backdoor Roth conversion get reported as a taxable distribution like in the case I just described? Did a rollover from a 401k get miscoded as a withdrawal?" The forms only show that money moved. The tax return must tell the right story about why it moved.
Now, before I give you the last red flag that millionaires are looking for, if you want a second set of eyes on your tax return, not just to file it, but to understand what it's revealing about your financial plan, click the link in the description below and reach out to our team for a second opinion. We use specialized software that helps us identify these red flags and provide scenarios and forecasting that can help you make smarter financial decisions.
If your CPA is doing tax preparation and your advisor is doing planning, you're probably assuming those two worlds are connected. But unless someone makes sure they are connected, they probably are not. Everybody on your team can be competent, they can be experts, and you can still get hurt because the information never got communicated and it wasn't coordinated.
This is not about bashing CPAs. Good CPAs are valuable. But if the CPA does not know the planning strategy and the advisor never reviews the return, the client becomes the messenger and that's not a good system. If your advisor and your CPA are not on the same page, let us help. Because your investments, your retirement plan, and your tax strategy should not live in separate worlds.
Now, finally, after looking for what's on the return, millionaires look for what isn't there. They read the tax return to find the ghosts, if you will, of missed opportunities. Was it a year with unusually low income? Maybe from a business transition or a sabbatical. Now, that shows up as a lower-than-usual adjusted gross income year. And a normal person would be perfectly happy to pay less tax for that year.
A millionaire on the other hand or our planning team, we see that as a missed opportunity. A low income year is the perfect time to do a Roth conversion to move money from a pre-tax IRA to a tax-free Roth and pay the tax at a much lower marginal rate. Seeing a low AGI without a corresponding Roth conversion, for example, is a sign of passive tax management, certainly not proactive tax management. This is the kind of thing that people only see after the year is over.
They say, "We had a lower income year." I look at it and say, "That may have been a Roth conversion window that we missed." Same tax return, different set of eyes.
That strategy lets you avoid paying capital gains tax on the stock's growth, and you still get the deduction based on its full fair market value. Absolutely a better move.
Was the business income structured correctly? Is their S-corp or LLC still the most tax efficient structure for their level of profit? This is the highest level of tax analysis. We're getting into more complex things at this point.
Okay, so let's get a little bit more complex. Let's talk business. So, was the business income structured correctly? Is their S-corp or the LLC, is that still the most tax efficient structure once they hit a certain level of profit? This is the highest level of tax analysis, and it's not just about verifying the past, it's about using the past as a diagnostic tool to make better decisions in the future. It's about asking, "What does this return tell me that we should have done differently, and what will we put in place to ensure we do it better next year?"
The next time you get your tax return, don't just flip to the last page. See it as a report card of your financial plan. That's what it is in a lot of ways. At the end of the day, your tax return is not the plan. It's the receipt for the plan you did or did not have.
