Does Your IRA Trigger a Wash Sale on Your Taxable Account? (w/Examples) + FAQs

This article reflects federal tax rules as of June 2026 and covers tax year 2025 (the 2026 filing season). State rules are addressed separately below. Tax law changes — confirm current figures with the IRS or a licensed professional before you file.

Quick Answer

Yes. Selling a security at a loss in your taxable account and buying the same or a “substantially identical” security in your IRA or Roth IRA within 30 days does trigger a wash sale for tax year 2025. Under Revenue Ruling 2008-5, that loss is disallowed — and permanently lost.

Why This Trap Catches So Many Investors

You sold a losing stock in your brokerage account to claim a tax deduction, then your IRA bought the same fund a week later. The IRS now treats that pair of trades as one wash sale, your loss vanishes from your tax return, and — unlike a normal wash sale — you never get it back. The dollars you expected to save shrink your refund or raise your bill instead.

This matters because the two accounts feel completely separate to you, but they are not separate to the IRS. The agency confirmed in Revenue Ruling 2008-5 that an IRA purchase counts as a wash-sale repurchase, and brokers usually do not flag this on your Form 1099-B because the two accounts are reported on different statements. According to Fidelity, you cannot get around the rule by buying back in a tax-advantaged account. That gap between what your broker reports and what the law requires is exactly where people get hurt.

What a Wash Sale Actually Is

A wash sale is a tax rule that blocks you from claiming a loss when you sell a security at a loss and buy the same or a “substantially identical” security within a short window. The rule lives in Internal Revenue Code Section 1091 and is explained in plain language in IRS Publication 550.

The window is 61 days total: the day you sell, the 30 calendar days before the sale, and the 30 calendar days after the sale. If a repurchase of a substantially identical security lands anywhere inside that window, the loss is disallowed. Per Fidelity, the rule applies to stocks, bonds, mutual funds, ETFs, and options.

The consequence of a normal wash sale is usually a deferral, not a death sentence. Normally the disallowed loss gets added to the cost basis of the replacement shares, and the old holding period carries over, so you recover the benefit later. The example below shows that normal mechanic — and the next section shows why the IRA breaks it.

A common misconception is that the wash-sale rule only matters if you trade fast or trade often. In truth, a single automatic dividend reinvestment or one routine IRA contribution can trigger it without any active trading on your part.

What you should do about it: before you harvest any loss, check every account in your household — taxable, IRA, Roth, and your spouse’s — for any purchase of the same security inside the 61-day window.

The IRA Twist: Why the Loss Disappears Forever

Here is the part that makes the IRA version uniquely painful. In a normal wash sale, your disallowed loss is added to the basis of the replacement shares, so you eventually claim it. But shares inside an IRA or Roth IRA have no recognized cost basis for capital-gains purposes, because gains and losses inside those accounts are never taxed as capital items.

Revenue Ruling 2008-5, effective for transactions on or after December 21, 2007, settled the question directly: when the replacement security is bought in your IRA, the wash-sale loss is disallowed and the basis of the IRA shares is not increased. As Fidelity puts it, the disallowed loss is “effectively forfeited, not deferred.”

The consequence is a permanent loss of the deduction. If you sold a stock at a $5,000 loss in your taxable account and your IRA bought it back inside the window, that $5,000 deduction is gone — you cannot use it this year and you cannot recover it later through a basis bump.

A common misconception is that you can simply “add the loss to the IRA shares’ basis” the way you would in a taxable account. You cannot, because the IRA has no basis to adjust for this purpose, which is the entire point the IRS made in the ruling.

What you should do about it: never let your IRA or Roth IRA buy a security you just sold at a loss in your taxable account within 30 days — set a calendar reminder for day 31, or use a non-identical replacement instead.

Which Situation Applies to You?

The answer depends on which account did the buying and what it bought. Find your case below, then read the matching example.

Repurchase in a Traditional IRA → wash sale applies, loss permanently disallowed under Rev. Rul. 2008-5. See Maria’s example.
Repurchase in a Roth IRA → same outcome; the ruling covers Roth IRAs explicitly. See David’s example.
Repurchase in your taxable account → ordinary wash sale; loss is deferred into basis, not lost. See the basis example above.
Partial repurchase (fewer shares than you sold) → only the matched portion is a wash sale; the rest of the loss is allowed. See Priya’s example.
Repurchase by your spouse’s account or a controlled corporation → the IRS treats this as a wash sale too; all household accounts count together.

Worked Example: The Full Wash Sale

Meet Maria, who in tax year 2025 bought 100 shares of an S&P 500 ETF in her taxable account for $10,000. By November the position is worth $7,000, so she sells all 100 shares to harvest a $3,000 loss.

Eight days later, her Traditional IRA’s automatic monthly contribution buys 100 shares of the same ETF for $7,050. Because the IRA repurchase falls inside the 30-day post-sale window, the entire $3,000 loss is a wash sale under Revenue Ruling 2008-5.

Here is the math, step by step:

What Maria Does	Tax Result for 2025
Sells 100 shares, realizes $3,000 loss	Loss reported on Form 8949
IRA buys 100 identical shares within 8 days	Triggers wash sale on full $3,000
Tries to add $3,000 to IRA share basis	Not allowed — IRA basis cannot increase
Net deductible loss for 2025	$0 — the $3,000 is gone forever

If Maria is in the 24% federal bracket, that lost $3,000 deduction costs her about $720 in tax she could have saved.

Worked Example: The Roth IRA Version

David sells 200 shares of a tech stock in his taxable account for a $4,000 loss in tax year 2025. Three weeks later he makes his annual Roth IRA contribution, and the Roth buys 200 shares of the same stock.

The Roth IRA gets the same treatment as a Traditional IRA under the ruling. David’s $4,000 loss is disallowed, and because Roth shares also have no capital-gains basis to adjust, the loss is permanently forfeited.

What David Does	Tax Result for 2025
Sells 200 shares, realizes $4,000 loss	Loss appears on his 1099-B
Roth IRA buys 200 identical shares in window	Wash sale on full $4,000
Recovery of the loss later	None — Roth basis is not adjusted

The lesson: a Roth IRA gives you no special escape. If anything, the loss is even more painful because future Roth growth is tax-free anyway, so you gained nothing and lost the deduction.

Worked Example: The Partial Sale

Priya owns 100 shares of a fund she bought for $5,000, now worth $3,000, so a full sale would create a $2,000 loss. In tax year 2025 she sells all 100 shares, then her IRA buys only 50 shares back within the window.

Only the matched 50 shares trigger the wash sale. Following the partial-match logic explained at Financial Ducks in a Row, half of the loss is disallowed and half survives.

Portion of Priya’s Sale	Tax Result for 2025
50 shares matched by IRA repurchase	$1,000 loss disallowed and forfeited
50 shares with no repurchase	$1,000 loss fully allowed

So Priya keeps a $1,000 deductible loss and forfeits the other $1,000. Partial repurchases create partial wash sales — the IRS matches share for share.

How Brokers Report It (and Why They Often Miss It)

Your broker reports sales on Form 1099-B and flags wash sales it can see. But a broker only sees inside the accounts it holds, so it generally cannot match a taxable-account sale at one firm to an IRA purchase — even at the same firm, because IRAs and taxable accounts are separate tax entities.

The consequence is that the cross-account wash sale is your responsibility to catch and report. The IRS expects you to apply the rule across all your accounts, even when no 1099-B shows the adjustment. Missing it means filing an incorrect return, and the IRS can disallow the loss on audit and add interest and penalties.

A common misconception is “if my 1099-B doesn’t show a wash sale, there isn’t one.” That is false for IRA-triggered wash sales, which almost never appear on the 1099-B.

Reporting It on Form 8949 and Schedule D

You report the sale and the wash-sale adjustment on Form 8949, then carry the totals to Schedule D. The wash sale does not disappear from your return — you report the sale, then back out the disallowed loss.

Follow these steps for tax year 2025:

Enter the sale on Form 8949 in the correct part: Part I for short-term holdings (one year or less), Part II for long-term.
In column (f), enter adjustment code W for “wash sale loss disallowed.”
In column (g), enter the disallowed loss as a positive number, which reduces the loss in column (h).
Carry the Form 8949 totals to Schedule D, then to Form 1040.

For a line-by-line walkthrough, see our guide on how to fill out Form 8949 and the related Schedule D instructions.

The deadline is the normal filing date: April 15, 2026, for tax year 2025 returns, or October 15, 2026, with an extension. Missing the adjustment means an inaccurate return you may have to amend on Form 1040-X.

Federal vs. State Treatment

The wash-sale rule is a federal rule, but it flows into most state returns automatically. Here is the difference between the two layers.

Federal Rule	State Treatment
Wash sale disallows the loss under IRC §1091	Most states start from federal adjusted gross income, so the disallowance carries over
Rev. Rul. 2008-5 forfeits the IRA-triggered loss	States following federal AGI generally honor the same forfeiture
Applies nationwide	States with no income tax (e.g., Florida, Texas, Washington) do not tax the gain or loss at all

Because most states begin their calculation from your federal income, the disallowed loss is already baked in before the state sees it. States with no personal income tax — including Florida, Texas, Washington, Nevada, South Dakota, Wyoming, Alaska, Tennessee, and New Hampshire (which taxes only certain interest and dividends through 2024) — simply do not tax investment gains or losses, so the wash-sale question never reaches a state return there.

A few states adjust from federal AGI or taxable income but do not decouple from the wash-sale rule itself, so the practical answer for nearly every filer is: if it is disallowed federally, it is disallowed on your state return too. Confirm with your state’s department of revenue if your state uses its own starting point.

How to Avoid the IRA Wash Sale

The cleanest fix is time or substitution. Per Fidelity, waiting until the 31st day after the sale to repurchase keeps you fully clear of the window.

Wait 31 days. Sell on July 1, do not let any account buy back until August 1.
Use a non-identical replacement. Sell an S&P 500 fund and buy a total-market fund instead, which Financial Ducks in a Row shows is not substantially identical.
Turn off automatic IRA reinvestment of the security around a harvest.
Pause scheduled IRA contributions that buy the same fund during the window.

Mistakes to Avoid

Letting an automatic IRA contribution buy the same fund — it triggers the wash sale silently and forfeits the loss.
Forgetting dividend reinvestment (DRIP) — automatic reinvested dividends count as repurchases and can disallow the loss, per Fidelity.
Assuming the 1099-B catches everything — cross-account IRA wash sales rarely appear, so you under-report.
Ignoring your spouse’s accounts — the IRS treats a spouse’s purchase as your own, disallowing the loss.
Counting only 30 days, not 61 — the window includes 30 days before the sale too.
Believing the Roth IRA is exempt — it is not; the same forfeiture applies.
Trying to add the loss to IRA basis — IRA shares have no adjustable basis, so the loss is simply lost.
Repurchasing on day 30 instead of day 31 — one day early voids the deduction.

Do’s and Don’ts

Do’s

Do check every household account before harvesting — because all accounts count together under the rule.
Do wait the full 31 days — because day 30 is still inside the window.
Do use a similar-but-not-identical fund — because that legally preserves the loss.
Do keep records of every trade date — because you must self-report cross-account wash sales.
Do consult a CPA for heavy trading — because overlapping windows get complex fast.

Don’ts

Don’t auto-reinvest dividends during a harvest — because reinvestment can trigger the wash sale.
Don’t assume separate accounts are separate to the IRS — because Rev. Rul. 2008-5 links them.
Don’t rely on your broker’s 1099-B alone — because it misses cross-account matches.
Don’t repurchase in any IRA inside 30 days — because the loss is forfeited forever.
Don’t ignore your spouse’s trades — because they are attributed to you.

Pros and Cons of Loss Harvesting Near IRA Activity

Pros

Harvesting losses lowers your taxable income — because allowed losses offset gains and up to $3,000 of ordinary income per year.
A done-right harvest is free money — because it converts a paper loss into a real tax saving.
Substitute funds keep market exposure — because you stay invested while harvesting.
Long holding periods can carry over — because in a normal (non-IRA) wash sale the clock continues.
Awareness prevents costly errors — because knowing the rule avoids permanent forfeiture.

Cons

An IRA repurchase forfeits the loss permanently — because no basis adjustment is allowed.
The rule is easy to trigger by accident — because contributions and DRIPs are automatic.
Brokers don’t warn you — because cross-account matches aren’t on the 1099-B.
Tracking across accounts is tedious — because you must monitor every household account.
“Substantially identical” is fuzzy — because the IRS gives no bright-line list.

What to Do Next

List every account in your household — taxable, Traditional IRA, Roth IRA, SEP/SIMPLE, and your spouse’s accounts.
Map the 61-day window around any loss sale (30 days before through 30 days after).
Check for matching purchases in all those accounts, including automatic contributions and DRIPs.
If you find an IRA match, report the wash sale on Form 8949 with code W and carry it to Schedule D.
If no match exists, claim your loss normally — and set a calendar block for the next harvest.
Call a CPA or tax attorney if you trade frequently, have overlapping windows, or already received an IRS notice. Expect to pay roughly $200–$500 for a focused consultation.

FAQs

Does buying in my IRA really trigger a wash sale on my taxable account?

Yes. Under Revenue Ruling 2008-5, a purchase in your Traditional or Roth IRA within 30 days of a taxable-account loss sale triggers a wash sale and disallows the loss for tax year 2025.

Is the disallowed loss gone forever or just delayed?

Gone forever. Unlike a normal wash sale that adds the loss to replacement-share basis, an IRA repurchase cannot increase the IRA’s basis, so the loss is permanently forfeited, not deferred.

Does the Roth IRA get a pass?

No. The ruling covers Roth IRAs the same as Traditional IRAs. A Roth repurchase inside the window forfeits the loss just as completely.

How long is the wash-sale window?

61 days total. It covers the 30 days before the sale, the sale day itself, and the 30 days after — so wait until day 31 to repurchase safely.

Will my broker show this on my 1099-B?

Usually no. Brokers generally cannot match a taxable sale to an IRA purchase, even at the same firm, so you must self-report the wash sale.

Do dividend reinvestments count?

Yes. Automatic reinvested dividends are treated as repurchases of a substantially identical security, per Fidelity, and can disallow the loss.

Does my spouse’s IRA count?

Yes. The IRS treats a security your spouse buys within the window as your own repurchase, triggering the wash sale.

What if I only buy back some of the shares?

Only the matched shares. A partial repurchase creates a partial wash sale; the unmatched portion of the loss stays deductible for tax year 2025.

Which form reports a wash sale?

Form 8949. Enter the sale, use adjustment code W in column (f), and put the disallowed loss as a positive number in column (g), then carry totals to Schedule D.

Does my state honor the wash-sale rule?

Almost always yes. Most states start from federal AGI, so the disallowance carries over; no-income-tax states like Florida and Texas don’t tax the loss at all.

How do I avoid it entirely?

Wait 31 days or substitute. Repurchase on the 31st day, or buy a similar but not substantially identical fund, to keep the loss deductible.

Can I fix a wash sale I already filed wrong?

Yes. File Form 1040-X to amend your return; the deadline is generally three years from the original filing date.
