It was the first time that Ron’s tax return had a balance due, and he kind of freaked out. On the recommendation of the advisor at his bank, Ron purchased municipal bonds because they were tax exempt. He was shocked to learn that his Social Security benefit became partially taxable. I explained that tax free muni interest was added in with other sources of income to determine if any Social Security income would become taxable. He immediately called his bank person, who assured him that the muni interest would not cost him any tax dollars. I had to explain the concept of Modified Adjusted Gross Income, or MAGI to her.
One way to understand MAGI, is to think of your Adjusted Gross Income, or AGI, as the bottom line, and to consider MAGI as the ‘fine print’. And you should always read the fine print. MAGI is your AGI plus a few things like tax-exempt municipal bond interest and excluded foreign income. It affects a basket-full of credits and deductions, and can bring some unpleasant surprises come tax time.
So what moving parts of your tax return can MAGI gum up?
- The deductibility of a Traditional IRA contribution
- Your ability to contribute to your Roth IRA
- The Child Tax Credit
- The Premium Tax Credit for health insurance
- Your premiums for Medicare, IRMAA
- The Net Investment Income tax
- The Additional Senior Tax Deduction
- The State and Local Tax Cap Expansion
What are you gonna do about it?
What I’m really talking about here is avoiding the MAGI surprise.
- Worker bees can use defined contribution plans and traditional IRAs to lower income. Of course, these things only defer the tax man’s bite.
- Here’s a great advantage of the Roth 401(k). If you know that IRRMA will be an issue in retirement, contributions to a Roth 401(k) will soothe the sting of paying tax now. Eventual Roth distributions do not affect MAGI.
- Fixed annuities are another tool for deferring income. Sadly, they share the same disadvantage as in item #1.
- If you are at least 70.5, using Qualified Charitable Distributions avoids the MAGI worksheet.
- Tax Loss Harvesting. No one likes to lose money, still, this method wipes out capital gains and up to $3000 of ordinary income per year from the IRS’s prying eyes. Remember, even if your income puts you in the 0% long term capital gain rate, they still contribute to both MAGI and state income tax (if your state has a tax).
- Taking full advantage of your Health Savings Account. Is there another method to deduct contributions, invest as you wish, and then withdraw the money tax free, and also avoid MAGI? These are a powerful tool for those eligible to have one.
- A Home Equity Line of Credit may help. If you have a big one time expense looming, and you are close to the IRMAA cliff, you can use your HELOC instead of taking a huge distribution from your IRA.
- Using Exchange Traded Funds, rather than managed funds in your brokerage account can cut down on those pesky capital gain distributions. Also, keeping those big dividend payers inside your IRA will help as well.
- If your income spiked due to retirement, divorce, or the death of a spouse, you can file form SSA-44, claiming a ‘life changing event’. This won’t lower your income, but can result in a one time reset of the ‘cliff’.

Thanks for your article pointing out AGI and MAGI. I learned that just a couple of years ago. However, my take is, do not be sad to pay higher taxes, it usually means you can more than afford it! We all would like no taxes, but that is no longer an option.
[Comment deleted because I thought better of it…. need more coffee before posting….]
I’m starting to look at future RMDs the same way. There was recently some discussion in another thread about very aggressive Roth conversions to reduce future RMDs/taxes. I did some math and it works, but the math is based on continued strong market performance. Of course we hope and expect this will be the case, but one never knows. So we’ll do some converting, but not too aggressively, and not high enough to cause higher MAGI to unduly impact things in the near term. If things turn south, we’ll be glad to have the money we would have spent on taxes to convert. If markets continue to do wonderfully, we’ll pay the tax and count our blessings.
”If things turn south” it will be another opportunity (decision 🤔) to do more Roth conversions, right ;)?
Depends on how far south, and when
Agree! When it comes to Roth conversions, tax arbitrage is usually the focus of discussion, but “portfolio return“ arbitrage (if that’s a proper term?) is usually less mentioned.
“He immediately called his bank person, who assured him that the muni interest would not cost him any tax dollars.”
The bank person made a big mistake by saying that, unless they made it clear that they only meant that the Muni income would not be DIRECTLY taxed by the federal government.
Thanks, Dan. Useful information.
I will forever don’t understand why IRS prevent seniors ability to invest into Health Saving Account, with long term care will be coming into view. It doesn’t make a lot of sense.
Tax revenue
Social Security taxability is not based on MAGI. It is based on combined income which includes AGI plus non-taxable interest plus half of Social Security benefits.
Again the illogical favoring of ROTH income, right? How can income taxable or not be treated differently when making any determination based on income. If anything, the tax free income should mean the ability to pay more for something, not less 😢🤑
Nice article Dan. I remain thankful my MAGI is my AGI.
Honestly you lost me at “tax nazi”. I’m a big fan of legal tax avoidance. However, throwing around such a term with its vile connotation is beneath the standards of this forum.
Adam, you’re right, totally. It is especially insensitive to anyone having ties to that era. I have edited that out of the piece. Thanks for your comment.
This is one of my pet peeves. Where is the logic in Roth distributions being excluded from MAGI while tax-free municipal bond interest is included?
In fact, where is the logic excluding any income for purposed of IRMAA and taxability of SS? Income is income, money is money.
Theoretically, a person could have a Roth income of $200,000 a year and be exempt from IRMAA premiums. That makes sense? And yet we complain about billionaires using loans🤑
It might make sense to include Roth earnings in the IRMAA calculation. However, the contributions were included in income/MAGI when you put the funds in. Including it again at withdrawal would be double dipping.
This would be similar to how your brokerage account is treated; you invest with after-tax funds and then only earnings are included as income/MAGI when withdrawn. Ken
Earnings only. Contributions were after tax as you say, but so were purchases of muni bonds so earnings there too.
I understand, Dick, and I suspect that your theoretical comment is already in practice. We could surely debate fairness inside the tax code. Speaking of which, despite having over 4 million words, the word “fair” appears in the tax code almost exclusively in the context of “fair market value,” rather than any philosophical definition of fairness.
A few years ago I read of a guy who put IPO shares in his Roth IRA when they had minimal value and later were worth millions later.
You’re probably thinking of Peter Thiel, founder of PayPal and I think the appreciated tax-free value of his Roth contribution has been widely estimated to be in the vicinity of $5 billion.
Great article with actionable recommendations! Thanks!
What is really interesting is that MAGI is calculated in different ways for different benefits. The MAGI for IRMAA is not the MAGI for the ACA.
Yeah, it’s confusing as all get out. Thank goodness for computer programs that do all the heavy lifting.
It seems like every time there’s a change to the tax code, a new worksheet is created. I can’t imagine doing tax returns by hand any longer.
