Why Taxes May Be Your Largest Retirement Expense

Common Assumptions About Retirement Costs

When most people picture the big expenses in retirement, they think about healthcare premiums, the cost of long-term care, maybe housing. And those are real costs. But in my experience working with families entering retirement, there is one expense that consistently catches people off guard.

Taxes.

Most of us assume that once the paychecks stop coming in, the tax bill naturally shrinks. Less income, fewer taxes. Makes sense, right? Not always. That’s why tax planning in retirement is so important.

The “Retirement Tax Surprise” Explained

We actually call this the retirement surprise at our firm because I see it over and over again. People get to retirement expecting that the hard part is behind them, that they saved and accumulated and now they get to enjoy it. Then they get their first full-year tax return as a retiree and realize they are paying just as much in taxes as they were when they were working. Sometimes more.

How Tax-Deferred Accounts Create Future Liabilities

Think back to your 30s. Your HR person told you to open that 401(k), your mom and dad told you to open that 401(k), and you were proud of yourself for doing it. That was not a bad decision. But here is what nobody emphasized at the time: every dollar you put in there was tax-deferred, meaning you have never paid taxes on that money.

Fast forward a few decades and for a lot of people that 401(k) or IRA is their largest pool of dollars, and every one of those dollars is going to be taxed as ordinary income the moment you start pulling it out. You pay based on whatever the rates happen to be at that time, and tax rates change. Sometimes up, sometimes down, and almost never because of anything you did.

How Retirement Income Is Taxed

Taxation of 401(k) and IRA Withdrawals

Let us start with the big one. Every withdrawal you take from a traditional 401(k) or IRA is taxed as ordinary income. Not capital gains, not some preferential rate. Ordinary income, same as a paycheck. If you are pulling $60,000 a year from your IRA, the IRS treats that the same as if you earned $60,000 at a job.

Social Security Tax Brackets: 0%, 50%, and 85% Taxation Levels

Social Security has its own taxation structure and it is not intuitive. There are three brackets: 0% where none of your benefit is taxed, 50% where half becomes taxable, and 85% where the vast majority is subject to tax. You do not get to choose your bracket. Your other income determines it.

And notice there is no gradual middle ground. You cross a line and suddenly half your Social Security is taxable. Cross the next line and it is 85%.

Pensions and Their Impact on Taxable Income

If you retire with a pension, there is a double-edged quality to it. You feel grateful to have guaranteed income, but it creates a locked-in layer of taxable income you cannot control. Stack that pension on top of IRA withdrawals and Social Security and the numbers climb fast.

Capital Gains and Investment Income

Then there is capital gains tax. Like Social Security, capital gains have three brackets: 0%, 15%, and 20%. The rate you pay depends on your total income, so all that IRA money taxed as ordinary income pushes you into higher capital gains brackets too. Your real estate, stocks, bonds, mutual funds, all of that profit gets taxed on its own schedule. A lot of people I talk to do not even know how much capital gain they are carrying until we look at it together.

The “Tax Chain Reaction” in Retirement

This is what I call the tax chain reaction. You take money from your IRA and that creates ordinary income tax. That income pushes your Social Security into a higher taxation bracket. That combined income then affects your capital gains rate and potentially your Medicare premiums. One withdrawal triggers a cascade. It compounds in ways most people do not anticipate until they are already in it.

The Importance of Tax Planning in Retirement

Tax-Forward vs. Tax-Backward Mindset

So what do we do about it? It starts with a mindset shift. I call it a tax-forward mindset because most of us are conditioned to think about taxes backwards. We file in April for the previous year, whatever happened already happened, and it is too late. You cross your fingers, hope it is not too bad, and if it is unpleasant the question becomes why is my tax bill so high. Legitimate question. The timing is just off.

Tax-forward planning flips that. Instead of reacting to last year you anticipate how the next dollar will be taxed so you can be intentional about where you pull it from.

Why Timing Matters in Withdrawals

Here is a real example. A client called our office wanting to withdraw $20,000 from her IRA to pay for a retaining wall. Just landscaping. The money was there, but when we ran the analysis that $20,000 IRA withdrawal would trigger income tax on the money itself and then set off the chain reaction, affecting her Social Security taxation and capital gains rate. The real cost was significantly more than $20,000.

She could have just taken it from her checking account. She told me she was so glad she called because she was just going to pull it from her IRA without thinking. That is the difference between tax-forward and tax-backward.

The Role of Financial and Tax Advisors: Bridging the Gap Between CPA and Financial Strategy

When it comes to taxes, it is important to have an adviser willing to talk about tax as it relates to strategy. What I see often is that when people ask their financial adviser about taxes they get referred to their CPA. Then they go to their CPA and ask about financial strategy and the CPA says talk to your financial adviser. Nobody is connecting the dots.

That gap is where a lot of money gets left on the table. Your income plan is where the tax strategy lives because how you source your income creates the taxation. Pull money arbitrarily from accounts without thinking about consequences and you might be triggering taxes you never needed to trigger.

Strategies to Reduce Taxes in Retirement

Roth IRA Conversions: Benefits of Tax-Free Growth and Withdrawals

One strategy that gets a lot of attention right now and for good reason is the Roth IRA conversion. The idea is straightforward: take money that is sitting in your traditional IRA where it is still tax-deferred and convert it to a Roth IRA. You pay the taxes now, but you do it at levels you know and at brackets you can target. The upside is that once it is in the Roth, that money grows tax-free and comes out tax-free in the future.

Consider this: if Social Security taxation goes up in the future and your IRA withdrawals would push you into that 85% bracket, having a Roth changes the math. You pull from the Roth instead, it does not count as income, and you stay in a lower Social Security bracket.

Strategic Withdrawal Planning: Minimizing Tax Impact Across Income Sources

Beyond conversions, the timing and sequencing of your withdrawals matters enormously. A lot of people wait until they are required to take distributions. But you do not have to wait. If you are in a lower tax bracket right now, maybe because you have retired but have not started Social Security or hit RMD age, that window is an opportunity. Pull money from your IRA now, pay taxes at a lower rate, and reduce the pile that will be taxed later at potentially higher rates.

Managing Required Minimum Distributions (RMDs)

Required minimum distributions are just what they sound like. At a certain age the IRS says you must start taking money out of your tax-deferred accounts whether you need it or not. If you have done nothing proactive leading up to that point, you could be forced into withdrawals that push you into higher brackets. Planning ahead for RMDs is not just smart, it is one of the most impactful things you can do for your long-term tax picture.

Using Health Savings Accounts (HSAs): Triple Tax Advantage Explained

If you are under 65, a health savings account is one of the most powerful tax tools available. I call it the triple benefit:

• Whatever you contribute lowers your taxable income in that year.
• Those dollars can be invested and grow tax-free.
• If you use the money for qualified health expenses in the future, you do not pay taxes when it comes out.

So you get a tax break going in, a tax break while it grows, and a tax break coming out. That is hard to beat. The catch is that this only works until age 65, so if you are younger than that and have access to an HSA, I would strongly encourage you to take advantage of it while you can.

Case Study: IRA Withdrawal vs. Cash Payment

I already shared the retaining wall example earlier, but let me put some numbers to it because this kind of scenario walks through our door all the time. Someone needs $20,000 for a home project, a car repair, a family event, whatever it is, and their instinct is to pull it from the IRA because that is where the money is sitting. It makes sense on the surface. But the tax math tells a very different story.

Let us say you are a retiree with $45,000 in Social Security income and a small pension. At that level maybe 50% of your Social Security is taxable and your overall tax rate is manageable. Now you pull $20,000 from your IRA. That $20,000 is taxed as ordinary income, so right away you might owe $4,000 to $5,000 in federal taxes on the withdrawal itself depending on your bracket. But that is just the beginning.

That extra $20,000 in income could push your Social Security taxation from the 50% bracket up to the 85% bracket. Suddenly a larger portion of your Social Security benefit is taxable too, which adds to your overall income, which could affect your capital gains rate on any investments you sold that year and could increase your Medicare premiums down the road. What started as a $20,000 withdrawal might actually cost you $7,000 to $9,000 or more in combined tax consequences when you add up the chain reaction.

Now compare that to just writing a check from your savings account. The money comes out, no taxable event, no chain reaction. The $20,000 costs you $20,000. That is it. Same retaining wall, dramatically different outcome depending on which account you pull from. This is exactly why having an income plan matters, because these are not obvious decisions and the wrong choice can cost you thousands of dollars that you did not need to spend.

How Additional Income Affects Social Security Taxation

I have a client, Sarah, in her 70s who still works at Orchestra Hall downtown. She loves the job and the hours. But her earned income combined with required distributions pushed her Social Security taxation to 85%. Without the extra earned income she might have been at 50% instead. That is a meaningful difference in how much of her Social Security she gets to keep, and it was not something she planned for.

Action Steps to Improve Your Tax Situation

I always like to leave people with steps they can act on right now. Knowledge without action is just trivia.

Step 1: Inventory Your Tax-Deferred Accounts

Take the time to add up every tax-deferred dollar you have. That old 401(k) from a previous employer, your current IRA, any other pre-tax accounts you have accumulated over the years. All of that money represents future tax liability. I am amazed at how often I sit down with someone and they have never totaled it all up. Get a clear picture of what you are working with.

Step 2: Understand Your Capital Gains Exposure

Capital gains are a separate tax schedule from ordinary income but they are affected by it. Look at the profit you are carrying across your investments: real estate, equities, bonds, mutual funds. A lot of people have no idea how much unrealized gain they are sitting on. That number matters because it is going to be taxed at some point.

Step 3: Consider Tax-Advantaged Accounts and Conversions

If you are still working or recently retired, ask yourself: are today’s tax rates likely to be lower than future rates? If the answer is yes or even maybe, that is a reason to consider Roth conversions now, HSA contributions if eligible, and strategic withdrawals while you still have control. The window is not infinite. Once RMD age hits, a lot of your flexibility disappears.

Final Thoughts: Taking Control of Retirement Taxes

The Value of Proactive Planning

If there is one thing I want you to take away from this, it is that you have more control over your taxes in retirement than you think. But that control requires being proactive. It means thinking forward instead of backward, having an income plan that accounts for taxation, and working with someone who connects the dots between your financial strategy and your tax reality.

Turning Knowledge into Action

The tax code is roughly 75,000 pages long. Nobody expects you to master that on your own. But the big things that affect retirees, the ones we talked about today, those are knowable and actionable. If you have questions about any of this or want to see how these strategies apply to your situation, reach out to my team at Guardian Resources. We love having these conversations and helping people take control of what can feel like an overwhelming topic.

Because at the end of the day, this is your money. You worked hard for it. You saved it. And you deserve to keep as much of it as possible.
