Getting to this point means you have already filled your retirement accounts, which puts you ahead of most households. But a taxable brokerage account is a different game with different rules, and applying retirement-account habits to it quietly costs a meaningful share of your return.
Why the rules change
Inside a 401(k) or IRA, nothing you do has an immediate tax consequence. You can rebalance, sell, switch funds and take distributions of dividends without a taxable event. That means you choose purely on cost and allocation.
In a taxable account, three things create tax:
| Event | Tax |
|---|---|
| Dividends and interest received | Annually, whether you withdraw them or not |
| Selling at a gain | On the gain, at short-term or long-term rates |
| Fund capital gains distributions | Annually, even if you never sold anything |
The third one surprises people most. A mutual fund manager selling holdings inside the fund passes the realised gains out to shareholders, who owe tax on them. You can be taxed on gains you did not cause, in a year you did not trade. This is the single strongest argument for ETFs in taxable accounts — see index fund vs ETF vs mutual fund for the mechanism.
Capital gains rates
Long-term rates apply to assets held more than one year and are substantially lower than ordinary income rates. Short-term gains — held one year or less — are taxed as ordinary income, at your full marginal rate.
There are three long-term brackets depending on taxable income, plus a 3.8% net investment income tax that applies above certain thresholds. High earners should factor that in when modelling.
The practical consequence is stark: the same $10,000 gain can be taxed at 0%, 15%, or a short-term marginal rate depending on your income and how long you held it. Two behaviours follow:
- Never sell at a gain inside eleven months if you can wait one more
- If you must realise gains in a low-income year, do it then — retirement, a career break, or a year with reduced bonus income are all opportunities to fill the 0% bracket
In the US, inherited assets generally receive a cost basis stepped up to market value at the date of death. Capital gains accrued during the deceased's lifetime are never taxed. For appreciated taxable holdings, this means the optimal strategy for many older investors is simply to hold and not sell — the gain disappears for heirs. This is estate-planning territory and worth raising with a professional if you have substantial appreciated positions.
What to hold
The taxable account should hold your most tax-efficient assets. This is asset location, and it is worth more than any fund-picking skill.
| Asset | Tax efficiency in a taxable account | Better location |
|---|---|---|
| Broad-market equity ETF, low turnover | Excellent | Taxable |
| Total international stock ETF | Good, plus a possible foreign tax credit | Taxable |
| Individual growth stocks held long-term | Good — you control the timing | Taxable |
| Municipal bond fund | Excellent for high earners — interest often federally tax-free | Taxable |
| Target-date index fund | Moderate | Either |
| Corporate or Treasury bond fund | Poor — interest is ordinary income | IRA |
| REIT fund | Poor — distributions mostly ordinary income | IRA |
| Actively managed high-turnover fund | Very poor | Nowhere — avoid entirely |
| Money market fund | Poor | IRA, or use for cash needs only |
The clean version of this: equity ETFs and municipal bonds in taxable; anything generating ordinary income in the IRA.

Choosing tax-efficient funds
Three metrics to check, in order:
1. Turnover ratio. Below 10% is excellent; below 25% is fine; above 50% means the manager is trading constantly and passing gains to you. Broad index funds run at single digits.
2. Tax-cost ratio. Morningstar and several brokers publish this — the annual percentage of return lost to tax, calculated from actual distributions. Compare it across funds you are considering. The gap between the most and least efficient broad equity funds is usually small; the gap between an index fund and an active one is often large.
3. Distribution yield. A fund distributing 4% a year in a taxable account is generating a permanent tax drag. Broad equity ETFs distribute closer to 1.3%.
Tax-loss harvesting
The one genuinely valuable technique unique to taxable accounts.
If you sell a holding at a loss, you can use that loss to offset capital gains. If losses exceed gains, up to $3,000 a year can offset ordinary income, with the remainder carried forward indefinitely.
The process:
- Identify a position with an unrealised loss
- Sell it
- Immediately buy a similar but not "substantially identical" replacement so you stay invested
- Bank the loss
Example: sell a total-market ETF at a loss, buy an S&P 500 ETF the same day. You remain fully invested in US equities with near-identical exposure, and you have realised a loss worth thousands against future gains.
The wash sale rule is the trap. If you buy a substantially identical security within thirty days before or after the sale, the loss is disallowed and added to the basis of the replacement. The window includes purchases in any account — including your IRA — which catches people automatically reinvesting dividends. Turn off dividend reinvestment on the affected holding before you harvest, or the reinvestment can wash part of the loss.
Worth doing: on broad positions, during market falls, in years when you have gains to offset. Not worth doing: manufacturing small losses, ignoring the wash sale window, or letting tax considerations drive you out of the asset class you actually want to hold.
What this account is for
A taxable brokerage is not a worse retirement account. It is a different tool with different advantages:
- No age restriction. You can withdraw at any time without penalty. This makes it the correct vehicle for early retirement, a house deposit in five to ten years, a career break or starting a business.
- No contribution limits. You can invest as much as you have.
- No required minimum distributions. You control the timing of gains indefinitely.
- Estate benefits. Step-up in basis, as above.
Practically, most people use it as a bridge account: money needed between early retirement and the age at which retirement accounts become accessible, or as a large flexible reserve sitting above the emergency fund and below retirement savings.
If you have not filled your retirement accounts yet, go back and fill them. The tax shelter inside a 401(k) or Roth IRA is worth more than any taxable-account optimisation. Our funding order guide covers the sequence.
Practical setup
- Open the account at the same broker as your IRA if possible — one login, one set of tax documents, and easier transfers.
- Turn on automatic monthly contributions. Same behavioural argument as everywhere else in investing.
- Turn dividend reinvestment on, unless you are actively harvesting losses or need the income.
- Enable specific-lot identification for cost basis. The default is usually FIFO; specific-lot lets you choose which shares to sell and minimise the gain. This setting must often be elected before you sell, so set it up on day one.
- Hold at least one year before selling anything, unless you are harvesting a loss.
- Keep records. Your broker tracks basis, but corporate actions, transfers between brokers and inherited positions can produce errors that are your problem to correct.
Moving an existing retirement portfolio's habits into a taxable account: rebalancing quarterly by selling, holding REIT and bond funds, and running dividend reinvestment while harvesting losses. Each is harmless in an IRA and expensive here. Before your first trade in a taxable account, decide what goes in it and what stays in the retirement account — that one decision does most of the work.
Is a taxable brokerage account worth it?
Yes, once your retirement accounts are filled. It is the only vehicle with no limits and no age restrictions, which makes it essential for early retirement or any goal inside ten to fifteen years. It just needs different holdings than a retirement account.
Do I pay tax if I do not withdraw the money?
Yes. Dividends, interest and capital gains distributions are taxable in the year received regardless of whether you withdraw them. Only realised capital gains from your own sales are within your control. This is why fund tax efficiency matters so much in this account type.
What is the best account for a house deposit in five years?
Not a taxable equity portfolio — five years is inside the range where a serious drawdown is possible. Use a high-yield savings account or a CD ladder timed to your purchase date. See our house deposit guide for the full breakdown.
Should I hold individual stocks in a taxable account?
If you want to, this is the account to do it in — you control the timing of gains, and long-term holding gets preferential rates. Keep it to money you can afford to lose entirely and to a small share of the portfolio. The tax efficiency of a concentrated position held for twenty years is genuinely good.
