Keep seeing this advice, to put bonds into tax-deferred accounts, rather than taxable. Can someone explain that to me in terms that a noob investor can understand? Don't mean to hijack..
Corporations pay taxes, and then you have to pay taxes again on your dividends from those corporations. To make up for this double taxation stock dividends get special tax treatment. Qualified stock dividends are taxed at a lower tax rate than bond income. Example: if you are in the 25% tax bracket stock dividends will be taxed at 15% and bond income at 25%. In addition, most of your return on a bond is the income, but stocks are part dividend income and part appreciation. That appreciation is also taxed at a lower rate, and it isn't taxed until you sell, which could be decades from now. This means the assets are allowed to grow partially tax deferred.
Would you rather pay 25% taxes NOW or 15% decades from now?
Conclusion: If your AA calls for bonds then you need bonds. You have to put the bonds somewhere, but for the reasons mentioned above you don't want them in your taxable account. Put your tax efficient investments* in your taxable account. This leaves the bonds in the pre-tax IRA.
*Tax efficient investments: Stock index ETFs(no company preference), Vanguard index funds(equal in efficiency to ETFs), individual stocks(which I would ignore for other reasons).
