Asset Location and Rebalancing Under a Tax Constraint
Eleanor, 67, has $3.2 million: $1.1 million taxable brokerage, $1.6 million traditional IRA, $500,000 Roth IRA. She draws $140,000 gross annually and is in the 24% federal bracket plus 5% state; NIIT applies to her investment income. Her taxable account currently holds investment-grade corporate bonds yielding 5.0%, while her IRA holds municipal bonds yielding 3.1% because 'the munis were the safe ones.' Her IPS targets 55/45 with a 10% band. Equities rallied, pushing the portfolio to 63/37. She wants to rebalance without adding taxable income and asks whether the bond placement matters. She also has $60,000 of unrealized losses in a legacy stock position in the taxable account.
1. Does the bond placement matter? Quantify before answering.

Yes, and the current placement is backwards. Approximate after-tax yields:
| Asset / account | Pre-tax yield | Tax treatment | After-tax yield |
|---|---|---|---|
| Corporate bond in taxable | 5.0% | 24% federal + 3.8% NIIT + 5% state = 32.8% | 5.0 x (1 - 0.328) = 3.36% |
| In-state muni in taxable | 3.1% | 0% federal, 0% state | 3.10% |
| Corporate bond in IRA | 5.0% | deferred; ~29% at withdrawal | ~3.55% equivalent |
| Muni in IRA | 3.1% | deferred; ~29% at withdrawal | ~2.20% equivalent |
Placement A (current): muni in IRA 2.20% + corporate in taxable 3.36% = 5.56% per dollar of each. Placement B (swapped): corporate in IRA 3.55% + muni in taxable 3.10% = 6.65%.
B is better by roughly 1.1 percentage points on the bond sleeve. The general rule 'bonds belong in the IRA' is wrong here because the muni's tax exemption is wasted inside the IRA. Caveats: the muni must be in-state to avoid state tax; check credit quality and duration; the IRA comparison ignores the time value of deferral and RMD timing, which strengthens the case slightly. If she has no in-state muni of acceptable quality, the advantage narrows and may reverse.
2. How should she rebalance from 63/37 to 55/45 without creating taxable income?
Read the worked answer
Reduce equity by 8% of $3.2 million = $256,000. Do it inside the tax-deferred accounts:
- In the IRA, sell $256,000 of equities and buy corporate bonds. This is tax-free and also begins correcting the bond location.
- In the IRA, sell the municipal bonds and buy the corporate bonds she needs.
- In the taxable account, sell the corporate bonds (minimal gain if near par) and buy the in-state munis.
Net effect: equity falls to 55%, corporates sit in the IRA, munis sit in taxable, and no capital gain is realized. Do not use the $60,000 harvested losses for this rebalance; they are not needed and should be preserved. If the taxable corporate bonds carry gains, check before selling; if gains exceed the losses, swap only the amount that can be offset. Re-check the 10% band and set a calendar review rather than reacting to headlines. Also confirm the IRA sale does not disturb any pending RMD calculation; RMD is based on prior-year balances, so this year's trade does not change this year's RMD.
3. What should she do with the $60,000 of unrealized losses, and what is the trap?
Read the worked answer
Harvest them, but do not force a use. The losses first offset realized capital gains; up to $3,000 per year offsets ordinary income; the rest carries forward indefinitely. Because she is drawing $140,000, she will likely have some realized gains from rebalancing or distributions, so the losses have value.
The traps:
- Wash sale: if she repurchases the same or substantially identical security within 30 days before or after, the loss is disallowed. Use a different but similar fund or wait 31 days.
- Harvesting for its own sake: a loss that is never used is worth less than the risk taken to create it. Pair it deliberately with gains.
- State treatment: confirm the state conforms to federal capital loss rules.
- Basis and step-up: if the legacy stock is intended for heirs or charity, the loss may be better used now; if it is intended for a charitable gift, do not harvest and then donate the cash. Preserve the loss until a gain appears. Do not burn it on a low-value transaction.
