How Retirees Use Three Accounts to Pull $110,000 a Year and Pay $0 in Federal Tax in 2026

Picture a married couple, both 67, who need $110,000 to cover their 2026 spending. Their savings sit in three places: a traditional 401(k), a Roth IRA and a Roth 401(k). Neither spouse has claimed Social Security yet. Which account each dollar comes from will set their federal tax bill.

A commenter on Reddit’s r/personalfinance put the core idea simply. A retiree with no other income gets “full access to the standard deduction (effectively a 0% bracket)”. For a couple over 65 in 2026, that 0% bracket is wider than most people assume.

How $47,500 of Pretax Money Leaves the Tax Return

Traditional 401(k) distributions are taxable to the person who receives them. Qualified Roth 401(k) distributions are excluded from gross income, and qualified Roth IRA withdrawals get the same treatment. That means only the traditional dollars need a deduction to cover them.

In 2026, the couple has three deductions working for them. The standard deduction for married couples filing jointly is $32,200. The extra deduction for being 65 or older adds $3,300 for the two of them. The new senior deduction allows $6,000 per qualifying spouse, or $12,000.

Those deductions add up to $47,500, which exactly matches the taxable withdrawal. Taxable income comes to zero, and so does the federal tax bill.

Same Spending, a $7,004 Bill

Now say the couple pulls the full $110,000 from the traditional 401(k). Their taxable income rises to $62,500. The 2026 brackets tax the first $24,800 at 10% and the rest at 12%.

The result is roughly $7,004 in federal tax. They spend the same amount from the same balances. Taking out all of it from one account is what triggers the bill.

Four Conditions Behind the $0 Result

1. Both Roth withdrawals must be qualified. Withdrawals must come after age 59½ and after a five-tax-year period, according to IRS Publication 590-B. For a Roth 401(k), that clock starts with your first Roth contribution to that particular plan, under § 402A(d)(2)(B).Both spouses must be 65 and file jointly. A married couple can claim the senior deduction only on a joint return, and each spouse’s Social Security number must be on the return, per § 151(d)(5)(C).
2. Income must stay under the phaseout. The senior deduction shrinks by 6% of modified adjusted gross income (MAGI) above $150,000, and it covers tax years before 2029 only. At this income, the couple has plenty of room. They also stay far below the $218,000 point where the  Medicare premium surcharge known as IRMAA starts.
3. They can have no other taxable income. Bank interest, brokerage dividends, a pension or capital gains each use up part of the $47,500 deduction. That income means one less tax-free traditional dollar for every dollar.

Social Security Puts a Tax Bill Back

Say the couple claims Social Security and collects the average benefit for a retired couple, $3,208 a month, or $38,496 a year. They keep the traditional withdrawal unchanged and reduce the Roth withdrawals to $24,004 to keep total spending the same.

The IRS test for taxing benefits adds half of your benefits to your other income and ignores Roth withdrawals. Every traditional dollar counts in full. Their total on that test comes to $66,748, well above the $44,000 joint threshold. About $25,336 of their benefits becomes taxable, which results in roughly $2,544 in tax.

In this income range, each extra traditional dollar also makes more of their benefits taxable. A 12% bracket ends up being about 22%.

Three Moves Before December 31

1. Add up every taxable dollar first. Count interest, dividends and any pension income, then set the traditional 401(k) withdrawal so it fills only the deduction room that’s left.
2. Check each Roth’s five-year clock. Find the year of your first Roth IRA contribution and your first Roth contribution to each Roth 401(k) plan. A nonqualified withdrawal of Roth earnings could undo the plan.
3. Draw down traditional money before claiming Social Security. Once benefits start, each traditional dollar can bring more tax, and the senior deduction runs out after 2028. Traditional money withdrawn or converted before benefits start can have a lower tax cost.

Two couples with the same balances can owe very different amounts of tax. The order of withdrawals and the year you claim Social Security decide most of the bill. That silent stretch between the last paycheck and the first required withdrawal is the cheapest tax rate most retirees will ever see again, and we sized up how to use it in a free Roth guide here.
