Roth Conversions Are Just the Beginning: Understanding Retirement Tax Events


Tax season has a funny way of making people look backward.
We focus on what already happened — last year’s income, last year’s deductions, last year’s bill. But for many people, tax season is also when they first realize that some financial decisions don’t just affect today — they create long-term tax consequences.
One of the most talked-about examples right now is the Roth conversion. And while Roth conversions can be a useful strategy, they’re also a perfect illustration of a bigger issue most people overlook: many retirement decisions trigger tax events — often without people fully realizing it at the time.
What Is a Tax Event?
A tax event is any action that creates taxable income or changes how your money is treated by the IRS — and sometimes by your state as well.
Some tax events are obvious, like earning income or selling an investment for a gain. Others are less obvious, especially when it comes to retirement planning. That’s where many people get caught off guard.
Roth Conversions: A Popular - and Taxable - Move
A Roth conversion happens when pre-tax retirement money, such as a Traditional IRA or 401(k), is moved into a Roth account.
What many people don’t realize until tax season arrives is that the converted amount is treated as taxable income in the year the conversion occurs. Depending on the size of the conversion, this can push someone into a higher tax bracket or affect deductions, credits, or future Medicare premiums.
A Roth conversion isn’t inherently good or bad — but it is a tax event. And like any tax event, it should be planned, not done reactively.

Required Minimum Distributions (RMDs)
Starting at age 73, the IRS requires withdrawals from certain retirement accounts. These withdrawals are taxable and can increase overall tax liability. They may also cause more of a retiree’s Social Security benefits to become taxable.
Social Security Becoming Taxable
Depending on total income, up to 85% of Social Security benefits can be subject to federal income tax. Many people don’t realize this until other income sources push them over the threshold.
Capital Gains Events
Selling investments, rebalancing portfolios, or selling a business can all trigger capital gains taxes. Timing and strategy often matters more than expected.
Cryptocurrency Transactions
Cryptocurrency, including Bitcoin, is treated as property for tax purposes — not currency. As a result, selling, trading, or even using crypto to purchase goods or services can trigger capital gains taxes. Many people are surprised to learn that crypto transactions create taxable events even when no traditional cash is involved.
State-Level Tax Treatment in Retirement
Not all income is treated the same at the state level. Some states tax certain types of retirement income more heavily than others, while some assets are treated differently under state tax rules. This can significantly affect net income in retirement.
Why Tax Diversification Matters
One of the most common retirement planning mistakes is having all future income taxed the same way. When all retirement income comes from tax-deferred accounts, flexibility is limited later in life.
Tax diversification — having money treated differently under the tax code — can create more control over when and how taxes are paid. That flexibility can matter just as much as how much money is saved.
Planning vs. Reacting
Tax preparation focuses on what already happened. Tax planning looks ahead.
For many people, tax season is the moment they realize they’ve been reacting instead of planning. That realization isn’t a failure — it’s an opportunity to make more informed decisions moving forward.
