Why asset placement matters
Taxes can shave a substantial portion off investment returns over time. Two portfolios with identical pre-tax returns can end up with very different after-tax results depending on where individual holdings live. Asset placement—also called asset location—looks beyond asset allocation and focuses on the tax character of each holding and the account that houses it. That makes it a high-impact, low-cost way to improve long-term outcomes.
Authoritative tax rules matter. For example, Required Minimum Distributions (RMDs) apply to tax-deferred retirement accounts and the current RMD rules are set and explained by the IRS (see: https://www.irs.gov/retirement-plans/retirement-plans-faqs-regarding-required-minimum-distributions). The Consumer Financial Protection Bureau also highlights the importance of tax-aware decisions in retirement planning (https://www.consumerfinance.gov/). Use these sources when you need the legal details for implementation.
Core placement rules you can apply today
These are practical, widely used rules-of-thumb that reflect typical tax behavior of asset types:
-
Put tax-inefficient or high-cash-yield investments in tax-deferred accounts. Examples: taxable bonds, bond funds that generate ordinary income, REITs and other vehicles that produce non-qualified dividends or ordinary-income distributions. Because these generate ordinary income taxed at your top marginal rate, placing them in a traditional 401(k) or IRA avoids annual taxation and allows compounding on pre-tax dollars.
-
Put high-growth, low-current-income investments in Roth or tax-exempt accounts. Examples: small-cap growth funds, emerging-market equities, and other holdings expected to appreciate substantially. Roth IRAs (and Roth 401(k) accounts, where available) let that growth be withdrawn tax-free, which is especially valuable if you expect to be in an equal or higher tax bracket in retirement.
-
Use taxable accounts for tax-efficient equities and municipal bonds. Index funds and ETFs with low turnover, tax-managed funds, and municipals (for federal tax-exempt interest) are usually good fits in taxable accounts because they generate qualified dividends, long-term capital gains, or tax-free interest that experience preferential tax treatment. Note: municipal interest can be subject to state tax if the bond is out-of-state, so check your state rules.
-
Consider tax-coordination for accounts with different tax rules. For example, prioritize filling your Roth with assets that would otherwise be taxed heavily on withdrawal in a traditional IRA. Conversely, if you already hold a large taxable portfolio of tax-efficient index funds, you might prefer to use tax-deferred accounts for income-producing investments.
Typical placement by asset (summary)
- Equity index funds (broad-market ETFs): Taxable or Roth — because index ETFs are tax-efficient and may benefit from qualified dividends/long-term capital gains.
- Active equity funds (high turnover): Roth or tax-deferred — to avoid frequent taxable distributions.
- REITs: Tax-deferred accounts — REIT distributions are often ordinary income; tax-deferral reduces current tax drag.
- Taxable bond funds / corporate bonds: Tax-deferred accounts — interest is ordinary income.
- Municipal bonds: Taxable accounts (or taxable-bond substitutes in taxable) — municipal interest is usually federally tax-exempt and can be attractive in taxable accounts.
- International equities / Emerging markets: Roth or taxable depending on dividend profile and your tax expectations.
These are starting points; individual circumstances (tax bracket, state taxes, expected future tax rates) can change the best home for a given asset.
Advanced levers to improve results
-
Roth conversions: Converting a portion of a tax-deferred balance to a Roth in a lower-income year creates future tax-free growth and distribution flexibility. This can be an effective tool to relocate future growth to a tax-exempt bucket.
-
Tax-loss harvesting: For holdings in taxable accounts, harvest losses to offset gains or up to $3,000 of ordinary income per year; unused losses carry forward. This reduces the tax cost of rebalancing and can improve after-tax returns.
-
Use tax-efficient wrappers: ETFs and tax-managed mutual funds generally generate fewer taxable distributions than high-turnover mutual funds, making them preferable inside taxable accounts for many situations.
-
Consider Net Investment Income Tax (NIIT) and Medicare surtaxes: High earners face additional surtaxes on investment income (e.g., the 3.8% NIIT) and higher Medicare premiums tied to income. Asset placement can mitigate some of this by shifting taxable distributions into accounts that reduce reported investment income.
Practical step-by-step process to implement placement
- Inventory: List accounts (taxable, traditional tax-deferred, Roth) and holdings. Document cost basis, expected income generation, and turnover.
- Rank by tax profile: Label each holding as tax-efficient (low expected current taxable distributions) or tax-inefficient (high interest/dividend distributions taxed at ordinary rates or frequent realized gains).
- Apply placement rules: Move tax-inefficient assets into tax-deferred accounts and high-growth assets into Roths where possible. Keep tax-efficient equities and municipal bonds in taxable accounts.
- Evaluate constraints: Check plan rules (some 401(k)s restrict fund choices), transaction costs, and potential tax consequences of selling (capital gains in taxable accounts).
- Use rebalancing windows: Rebalance across accounts using new contributions, dividend reinvestments, and future trades to avoid generating unnecessary taxable events.
- Reassess annually: Update placement when tax laws, account balances, or investment objectives change.
Example scenarios (illustrative)
-
A 45-year-old maxing a 401(k) and a Roth IRA holds a REIT ETF in their Roth and a broad-market index ETF in taxable. Because the REIT distributions would be taxed at ordinary rates if held in taxable or a traditional IRA, placing it in the Roth removes future tax friction — any future growth and distributions can be tax-free after qualified withdrawal.
-
A retiree with high fixed income chooses to hold a taxable municipal bond ladder in a brokerage account to reduce federal income tax on interest, while shifting corporate bond funds into a traditional IRA to avoid ordinary income taxation during accumulation.
In my advisory practice I’ve observed measurable results: modest changes in placement often grow materially over decades because avoided taxes compound. In one prolonged client engagement, reallocating tax-inefficient holdings into tax-deferred accounts and shifting growth assets into Roth vehicles resulted in lower lifetime tax bills and more flexible retirement cash flow.
Common mistakes and how to avoid them
- Treating account balances as interchangeable without checking tax features. Don’t move assets solely to chase a short-term tax change; consider transaction costs and long-term benefits.
- Ignoring state taxes and AMT/NIIT implications. Federal tax benefits may be offset or amplified by state rules—check state tax codes and consult a tax professional.
- Over-trading in taxable accounts. Frequent turnover increases taxable gains; prefer tax-efficient vehicles in taxable accounts.
- Forgetting RMD timing and impacts. Required Minimum Distributions from traditional IRAs and 401(k)s begin under current law in later retirement (see IRS guidance). RMDs can push you into higher tax brackets if not planned for.
When to get professional help
If you have multiple accounts, complex investment types (private equity, taxable annuities, concentrated stock positions), or expect large income swings, a coordinated plan with a tax professional or financial planner pays off. Tax rules change and personal circumstances (estate plans, charitable giving, business ownership) can alter optimal placement dramatically.
