Common Tax Traps in Retirement Income

 
 

Taxes don’t end when you stop working — they just get trickier.

Every account type you own is taxed differently. Traditional IRAs and 401(k)s are fully taxable. Roth accounts are tax-free. Brokerage accounts have capital gains. The mix of where your income comes from determines how much you actually keep.

One of the biggest mistakes I see is waiting until the Required Minimum Distribution (RMD) age to take withdrawals from an IRA. That often means a few years of low taxes followed by years of unnecessarily high taxes — and it didn’t have to be that way.

The real trap is when all your income comes from one bucket — usually a large IRA.

Every withdrawal pushes you into higher brackets and can make more of your Social Security taxable.

Good retirement tax planning looks ahead. It balances withdrawals across accounts, fills lower tax brackets each year, and uses Roth conversions strategically.

It’s not about avoiding taxes — it’s about controlling when and how you pay them.
