Asset location: which account each investment goes in

The same investments can cost you a different amount of tax every year depending on which account holds them. This shows how much you could avoid just by putting each one in the right place, which is called asset location.

How much is in each account
Traditional means pre-tax money: a traditional 401(k) or IRA. Roth is a Roth 401(k) or Roth IRA.
What you own, across all of them
These should add up to the same total as your accounts.

    How the math works

    In a traditional or Roth account, interest and dividends aren't taxed as they come in. In a regular taxable brokerage account, they are, every year. So it makes sense to keep the investments that throw off the most taxable income inside the traditional and Roth accounts, and leave the ones that are cheapest to hold in the taxable account.

    For each investment, this figures the yearly federal tax on holding it in a taxable account, at your 2026 rates:

    If your income is over $200,000 single or $250,000 married filing jointly, the 3.8% net investment income tax goes on top of all of it, REIT dividends included.

    The best placement fills your traditional and Roth space with the investments that cost the most to hold first, and whatever doesn't fit goes in the taxable account. The worst placement does the opposite. The difference between the two is the yearly tax you can avoid, and it repeats every year.

    Inside the traditional and Roth space, stock funds go in the Roth first and bonds in the traditional account. That's not about this year's tax, since both accounts shelter it. It's that a Roth's growth is never taxed, so you'd want the investments you expect to grow the most in there, and stocks have grown more than bonds over long periods. That's an expectation, not a guarantee.

    I put a lot of my high-dividend stocks, particularly my REITs, in IRAs for exactly this reason (I talk about it here). But the right answer depends on your own accounts and rates.

    What this leaves out

    It's a rule of thumb, not a plan. It leaves out capital gains distributions that funds pay out, municipal bonds (their interest is free of federal tax, so for people in high brackets they can make sense in a taxable account), state taxes, and the foreign tax credit. Many international funds pay foreign taxes you can usually claim as a credit in a taxable account, but not inside an IRA, which makes them a bit cheaper to hold in taxable than shown here.

    It also leaves out the tax you'd owe selling something in a taxable account to move it. Rearranging inside your traditional and Roth accounts doesn't trigger tax, but selling in a taxable account can, and a one-time tax bill can wipe out years of savings. Don't sell to rearrange without running the numbers in the capital gains calculator first.

    And it uses one yield per investment. Real yields change, and so does how much of a fund's dividend is qualified; your 1099-DIV shows the actual split.
