What’s the Difference Between Covered and Noncovered Shares? (w/Examples) + FAQs

This article reflects federal IRS rules as of June 2026 and covers tax year 2025 (the 2026 filing season). State rules vary and are noted separately. Tax law changes — confirm current figures before you file.

Quick Answer

Covered shares are those your broker must report a cost basis for to the IRS on Form 1099-B; noncovered shares are not. Covered status depends on when you bought the security — stocks bought on or after January 1, 2011, mutual funds and DRIPs on or after January 1, 2012, and most bonds and options on or after January 1, 2014. With noncovered shares, you must supply the basis yourself.

The difference matters most at tax time, when you sit down with your Form 1099-B and try to figure out which numbers the IRS already has — and which ones you must dig up on your own. For noncovered shares, the broker may leave the cost basis box blank, and if you also leave it blank, the IRS treats your basis as zero and taxes the entire sale. That single gap can turn a small gain into a large, fake one and cost you hundreds or thousands in tax you do not actually owe.

The stakes are real and the timing is tight. The IRS receives a copy of every 1099-B you do, so any mismatch between what you report and what your broker reported can trigger a CP2000 notice months later. Roughly 40 million Forms 1099-B are filed each year, and a large share involve noncovered lots from old accounts, inherited shares, or transferred positions — exactly the ones where basis errors hide.

What “Cost Basis” Means and Why It Drives Everything

Cost basis is what you paid for an investment, adjusted for things like commissions, reinvested dividends, splits, and return of capital. It is the number the IRS subtracts from your sale proceeds to find your taxable gain or loss. If you sell stock for $5,000 and your basis is $3,000, your taxable gain is $2,000 — not the full $5,000.

The reason cost basis sits at the center of this topic is a 2008 law. The Emergency Economic Stabilization Act of 2008 added cost-basis reporting rules under Internal Revenue Code §6045(g). Before this law, brokers reported only your proceeds — the cash you received — and you were on your own for basis. After it, brokers had to start reporting basis too, but only for securities you bought after certain dates.

That split — basis the broker reports versus basis you report yourself — is the entire covered-versus-noncovered distinction. Covered means the law requires your broker to track and report basis to the IRS. Noncovered means it does not, usually because you bought the share before the rule kicked in for that security type. The consequence of misunderstanding this is concrete: people assume a blank basis box means the share is worthless or that they owe tax on the full sale, when really it just means they must fill in the number.

If you ignore a noncovered lot’s missing basis, the IRS defaults your basis to $0 and taxes 100% of the sale. The fix is simple but it is your job — find your purchase records and enter the real basis on Form 8949. The misconception worth killing now: a noncovered share is not a tax penalty or a problem share. It is just a share where the paperwork burden falls on you.

Covered vs. Noncovered: The Core Difference

The cleanest way to see the difference is side by side. The split comes down to who reports the basis to the IRS and what you must do with it.

Feature	What It Means for You
Covered shares	Broker reports both proceeds and cost basis to the IRS on Form 1099-B; basis appears in box 1e; you generally copy it onto Form 8949 in Box A or D.
Noncovered shares	Broker reports proceeds but not basis (box 1e often blank); you must find and enter the basis yourself; it goes in Box B or E.

Covered status is set the moment you acquire the security, and it travels with the lot. A share you bought in 2010 stays noncovered forever, even if you sell it in 2025. A share you bought in 2015 is covered. Brokers usually print the word “covered” or “noncovered” right on your 1099-B next to each lot, so you rarely have to guess.

The practical consequence shows up in trust. For covered shares, the IRS already has your basis, so your return must match it or you must explain the difference with an adjustment code. For noncovered shares, the IRS has no basis on file, so you have more freedom — but also full responsibility for getting it right and keeping the records that prove it. The misconception here is that noncovered shares are not reported at all. They are: the proceeds still go to the IRS, only the basis is missing.

What to do about it: when your 1099-B arrives, sort every lot into covered or noncovered first. That one sorting step tells you which numbers you can trust as-is and which ones you must research before you file.

The Effective Dates That Decide Covered Status

Covered status is not one date — it phased in by security type over several years. Knowing the exact date for each type is the single most useful fact in this whole topic, because it tells you instantly which of your lots the broker tracked.

Stocks and Most ETFs — January 1, 2011

Equities were first. A share of corporate stock, an American Depositary Receipt (ADR), or most exchange-traded funds bought on or after January 1, 2011, is covered. Bought before that date, it is noncovered. The consequence: if you have held a single stock since the 1990s or 2000s, expect its basis box to be blank, and expect to supply the basis from old confirmations or statements. A common misconception is that long-held “blue chip” shares must be covered because they are well-known — date of purchase is all that matters, not the company. What to do: pull your original purchase confirmation now, before tax season, so you are not hunting for a 2003 trade slip in April.

Mutual Funds and DRIPs — January 1, 2012

Mutual funds and dividend reinvestment plans (DRIPs) came one year later. Shares bought on or after January 1, 2012, are covered; earlier shares are noncovered. DRIPs create a special trap because each reinvested dividend buys a tiny new lot, so a single fund can hold both covered and noncovered lots. The consequence of missing this is double-counting or undercounting basis across dozens of small lots. The misconception: that one fund is entirely covered or entirely noncovered — often it is mixed. What to do: ask your fund company for an average-cost or per-lot basis report, which most provide for free, before you try to fill in Form 8949.

Bonds, Options, Rights, and Warrants — January 1, 2014

The last main wave covered “less complex” debt instruments, options, rights, and warrants bought on or after January 1, 2014. More complex debt instruments were deferred to January 1, 2016. The consequence: a bond bought in 2013 or an option from 2012 is noncovered, so accrued market discount and premium adjustments are yours to compute. The misconception is that all bonds follow the 2011 stock date — they do not. What to do: for any fixed-income lot, check the acquisition date against the 2014 (or 2016) line before assuming the broker did the basis math.

Security Type	Covered If Acquired On or After
Stocks, ADRs, most ETFs	January 1, 2011
Mutual funds, ETFs, DRIPs	January 1, 2012
Less complex bonds, options, rights, warrants	January 1, 2014
More complex debt instruments	January 1, 2016

Which Situation Applies to You?

The answer changes depending on how you got the shares and when. Find your situation below and jump to the part that fits.

You bought shares yourself after the effective date — They are covered. The basis on your 1099-B is reliable; use Box A (short-term) or Box D (long-term) and usually copy the number straight across. Skip to the Form 8949 walkthrough.
You bought shares yourself before the effective date — They are noncovered. The basis box is likely blank; you must supply it from old records. Use Box B or E.
You inherited the shares — Almost always noncovered, with a stepped-up basis equal to the date-of-death value. See the inherited-shares section.
You received the shares as a gift — Noncovered, with carryover basis from the giver (special dual-basis rule for losses). See the gifted-shares section.
You transferred shares between brokers — Basis should carry over, but transfers sometimes strip basis history, turning a covered lot into one reported as noncovered. Check the new 1099-B carefully.

Worked Example: Covered Shares (The Easy Case)

Let’s make it concrete with real numbers for tax year 2025.

Maria bought 100 shares of a stock in March 2020 for $40 each, paying a $5 commission. Her basis is (100 × $40) + $5 = $4,005. Because she bought after January 1, 2011, the lot is covered. In June 2025 she sells all 100 shares for $70 each, with a $5 commission, for proceeds of (100 × $70) − $5 = $6,995.

Her broker reports both numbers on the 1099-B: proceeds of $6,995 in box 1d and basis of $4,005 in box 1e. Because she held the shares longer than one year, it is long-term and goes in Box D of Form 8949. Her taxable gain is $6,995 − $4,005 = $2,990. She copies the figures across, the IRS sees the same numbers, and there is nothing to reconcile. For most filers in 2025, that long-term gain is taxed at the 0%, 15%, or 20% rate depending on total income.

Worked Example: Noncovered Shares and the $0 Basis Trap

Now the case that bites people.

James inherited 200 shares from his father, who bought them in 2005. His father’s original cost is irrelevant — James gets a stepped-up basis equal to the fair market value on the date of death, which was $30 per share, or $6,000. Because the shares were acquired (by his father) before 2011 and basis history did not transfer, the broker reports them as noncovered and leaves box 1e blank.

In 2025 James sells all 200 shares for $50 each, for proceeds of $10,000. His 1099-B shows $10,000 in proceeds and nothing in the basis box. Here is the trap: if James copies the form as-is, the IRS treats his basis as $0 and taxes the full $10,000 as a gain. At a 15% long-term rate, that is $1,500 in tax.

The correct path: James enters the lot in Box E (long-term, basis not reported), writes proceeds of $10,000, and enters his real basis of $6,000 in column (e). His true gain is $10,000 − $6,000 = $4,000, taxed at 15% for about $600. By supplying the basis himself, James saves $900 in tax he never owed. The lesson: a blank basis box is not zero — it is your cue to do the work.

How Inherited and Gifted Shares Are Treated

Inherited and gifted shares are the most common source of noncovered lots, and they follow different basis rules — getting them backward is expensive.

Inherited Shares — Stepped-Up Basis

When you inherit stock, your basis is generally the fair market value on the date the owner died, not what they paid. This “step-up” often erases most of the built-in gain. If the estate elected an alternate valuation date, basis is the value six months after death instead. The consequence of using the wrong figure is overpaying tax (if you use the decedent’s old, lower cost) or underpaying and facing a notice (if you guess high). Inherited shares are also always treated as long-term, regardless of how long you held them. What to do: get a date-of-death valuation in writing from the broker or estate, and keep it with your tax records.

Gifted Shares — Carryover Basis

Gifted shares are different. You generally take the giver’s original basis — called carryover basis. A special dual-basis rule under §1015 applies if the share’s value dropped below the giver’s basis at the time of the gift: you use carryover basis to figure a gain but fair market value to figure a loss. The consequence of ignoring this is reporting a loss you cannot legally claim. Gifted shares are almost always noncovered because basis history rarely transfers with the gift. What to do: ask the giver, in writing, for their purchase date and cost before you ever sell.

Form 8949 and Schedule D: The Box-by-Box Walkthrough

Form 8949 is where every sale lands, and the covered/noncovered split decides which box you check. The form has two parts: Part I for short-term (held one year or less) and Part II for long-term (held more than one year). For tax year 2025, each part has boxes that depend on basis reporting.

The Six Core Boxes

Box A — Short-term, basis reported to the IRS (covered). Copy the broker’s basis; adjust only if it is wrong.
Box B — Short-term, basis not reported (noncovered). You enter the basis yourself.
Box C — Short-term, no 1099-B received at all.
Box D — Long-term, basis reported (covered).
Box E — Long-term, basis not reported (noncovered).
Box F — Long-term, no 1099-B received.

You file a separate Form 8949 (or section) for each box type, because the IRS groups transactions by how the basis was reported. The consequence of checking the wrong box is a mismatch with the broker’s filing, which can trigger a CP2000 notice and a proposed tax bill. For tax year 2025, the IRS also added digital-asset boxes (G–L), but for stocks and funds, A, B, D, and E cover almost everyone.

Columns, Adjustments, and Schedule D

Each row records a description, acquisition date, sale date, proceeds (column d), cost basis (column e), an adjustment code (column f), an adjustment amount (column g), and the resulting gain or loss (column h). When a covered share’s basis on the 1099-B is wrong, you do not erase it — you enter the broker’s figure, then use an adjustment code such as “B” in column (f) and the correction in column (g). The totals from each box flow to Schedule D, where short-term and long-term results net against each other to produce your final capital gain or loss. If your only covered transactions need no adjustments, you may be able to report them directly on Schedule D and skip Form 8949 for those lots.

Three Common Scenarios

These are the three situations that send people searching for this answer. Each shows the trigger and the consequence.

Scenario 1: Old Stock With a Blank Basis Box

What Happens	What It Costs or Saves You
You sell stock bought in 2008; broker reports it noncovered with no basis.	If you leave basis blank, IRS taxes 100% of proceeds; supply your real basis from old statements and you are taxed only on the true gain.

Scenario 2: A Mutual Fund With Mixed Lots

What Happens	What It Costs or Saves You
Your fund has pre-2012 noncovered lots and post-2012 covered lots from years of reinvested dividends.	Report covered lots in Box D using the broker’s basis and noncovered lots in Box E using the fund’s average-cost report; mixing them up triggers a mismatch notice.

Scenario 3: Inherited Shares Sold After Death

What Happens	What It Costs or Saves You
You inherit shares and sell them; the 1099-B shows them noncovered with no basis.	Enter the date-of-death stepped-up value as basis in Box E; this often wipes out most of the gain and saves hundreds or thousands in tax.

Three Named Examples in Action

Linda’s transferred account. Linda moved her brokerage account to a new firm in 2024. Shares she bought in 2016 were covered, but the transfer dropped the basis history, so the new broker reported them as noncovered with a blank box. Linda pulled the basis from her old broker’s records, reported the lots in Box D with the correct cost, and avoided a $0-basis overpayment.

Tom’s DRIP shares. Tom enrolled in a dividend reinvestment plan in 2009. His pre-2012 reinvestments are noncovered; his post-2012 ones are covered. He requested a per-lot statement, split the lots between Box E and Box D, and reported each correctly instead of guessing one basis for all of them.

Priya’s gifted stock. Priya’s aunt gifted her shares in 2023 that the aunt bought for $2,000 but were worth $1,500 at the gift date. Priya sold them for $1,200. Under the dual-basis rule, her loss is figured from the $1,500 value, not the $2,000 cost, giving a $300 loss — she reported it in Box E and kept the gift records.

7 Mistakes to Avoid

Leaving the basis box blank on a noncovered sale. The IRS defaults your basis to $0 and taxes the entire proceeds, often costing hundreds or thousands in tax you do not owe.
Assuming all your shares are covered. Old, inherited, gifted, and transferred lots are usually noncovered; treating them as covered means trusting a basis the broker never reported.
Using a decedent’s original cost on inherited shares. You lose the stepped-up basis and overpay tax on a gain that the step-up would have erased.
Checking the wrong Form 8949 box. Putting a noncovered lot in Box A or D, or vice versa, creates a mismatch with the broker’s filing and can trigger a CP2000 notice.
Overwriting a covered basis instead of using an adjustment code. When a covered figure is wrong, you must enter it and correct it in column (f)/(g); silently changing it looks like a mismatch.
Ignoring reinvested dividends in basis. Each reinvestment raises your basis; leaving them out inflates your gain and your tax bill.
Throwing away old purchase records. Without confirmations for noncovered lots, you cannot prove basis, and the IRS can deny it on audit.

Do’s and Don’ts

Do sort every 1099-B lot into covered or noncovered before you start your return — it tells you which numbers to trust.
Do keep purchase confirmations, statements, and date-of-death valuations, because basis proof is your responsibility for noncovered shares.
Do request a basis or average-cost report from your broker or fund company; most provide one free.
Do use adjustment codes in column (f) when a covered basis is wrong, rather than overwriting it.
Do treat a blank basis box as a signal to research, not as a basis of zero.
Don’t assume one fund is entirely covered or noncovered — many hold mixed lots.
Don’t report inherited shares with the decedent’s old cost when a step-up applies.
Don’t claim a loss on gifted shares without checking the dual-basis rule first.
Don’t skip Form 8949 for noncovered lots, since the IRS has no basis on file for them.
Don’t discard records right after filing; keep them at least as long as the IRS statute of limitations runs.

Pros and Cons of Each Type

Type	Pros and Cons
Covered shares	Pro: broker tracks basis, less work and fewer errors for you. Con: your return must match the broker, leaving little room for legitimate corrections without adjustment codes.
Noncovered shares	Pro: you control the basis, useful when you have records the broker lacks (like a step-up). Con: full record-keeping burden, and a blank box becomes a $0-basis trap if ignored.

Covered shares win on convenience: the basis is done for you, the numbers are reliable, and most lots need nothing but a copy-across. The downside is rigidity — if the broker’s number is wrong, you carry the burden of proving the correction. Noncovered shares flip this. The upside is flexibility and the chance to apply a basis the broker never had, like an inherited step-up. The downside is responsibility: miss the basis and you overpay, lose your records and you cannot defend the number on audit.

Does My State Follow These Rules?

The covered/noncovered distinction is a federal basis-reporting rule, so the cost basis you compute generally carries straight onto your state return. Most states that tax capital gains start from your federal adjusted gross income, so the basis you use on Form 8949 flows through automatically. Nine states — including Florida, Texas, and Washington for most income — have no broad personal income tax, so there is no state capital-gains layer at all.

A few states diverge. Washington taxes certain long-term capital gains above an annual threshold through a separate state capital gains tax, and a handful of states apply their own preferential rates or exclusions. The federal covered/noncovered status does not change in any state — it only ever affects what the broker reports to the IRS. What to do: use your federally computed basis as the starting point, then check your state revenue agency’s capital-gains page for any rate difference or exclusion before you file.

What to Do Next

Take these steps in order before you file your 2025 return:

Gather your 1099-B forms from every broker as they arrive in early 2026, and read each lot’s covered/noncovered label.
Pull records for every noncovered lot — purchase confirmations, old statements, gift letters, or date-of-death valuations.
Request a basis report from any broker or fund company that shows a blank basis box; most issue one free on request.
Sort lots by Form 8949 box (A, B, D, E) and enter each in the matching section, supplying basis yourself for B and E.
Total each box onto Schedule D and net your short-term and long-term results.
Keep all basis records for at least three years after filing, longer if large amounts are involved.
Call a CPA or tax professional if you have inherited shares, an estate with an alternate valuation date, mixed DRIP lots, or a transferred account that lost its basis history — these are the situations where a small fee prevents a large overpayment.

Frequently Asked Questions

What is the difference between covered and noncovered shares?

Covered shares have their cost basis reported to the IRS by your broker; noncovered shares do not. Covered status depends on the purchase date — generally stocks after 2011 and funds after 2012. For noncovered shares, you supply the basis yourself on Form 8949.

Are noncovered shares taxable differently than covered shares?

No. Both are taxed the same way on the actual gain. The only difference is who reports the cost basis to the IRS. With noncovered shares you must enter the basis yourself, but the tax rate on the gain is identical.

What happens if I leave the cost basis blank for noncovered shares?

The IRS treats your basis as $0 and taxes the entire sale proceeds. This can cost hundreds or thousands in tax you do not owe. Always enter your real basis from purchase records in column (e) of Form 8949.

When did cost basis reporting start?

January 1, 2011, for stocks. Mutual funds and DRIPs followed on January 1, 2012, and most bonds, options, rights, and warrants on January 1, 2014. Securities bought before each date are noncovered.

Are inherited shares covered or noncovered?

Almost always noncovered. Inherited shares usually show a blank basis box. Your basis is the stepped-up fair market value on the date of death, which you enter yourself, and the gain is always treated as long-term.

Why is my cost basis blank on my 1099-B?

Because the lot is noncovered. The broker reports your proceeds but is not required to report basis for shares bought before the effective date, inherited, gifted, or transferred without basis history. You must supply the basis.

Which Form 8949 box do noncovered shares go in?

Box B for short-term, Box E for long-term. These are the “basis not reported to the IRS” sections. Covered shares go in Box A (short-term) or Box D (long-term) instead.

Can one mutual fund have both covered and noncovered shares?

Yes. A fund or DRIP held across the 2012 effective date holds noncovered lots (pre-2012) and covered lots (post-2012). Report them in separate Form 8949 boxes using a per-lot basis report.

Do I still report noncovered shares if basis is missing?

Yes. The proceeds were reported to the IRS, so you must report the sale and supply the basis yourself. Skipping it triggers a mismatch and a possible CP2000 notice with a proposed tax bill.

How do I find the cost basis for old noncovered shares?

Check old broker statements, trade confirmations, or year-end summaries first. For inherited shares, use the date-of-death value. For gifts, ask the giver for their original cost. Some brokers reconstruct historical basis on request.

Does covered or noncovered status change when I transfer brokers?

The status should carry over, but sometimes the basis history does not. A covered lot can arrive at the new broker reported as noncovered with a blank box. Keep your old broker’s records to supply the correct basis.

Do states follow the federal covered/noncovered rules?

Generally yes, because most states start from federal income. The basis you compute federally flows to your state return. Nine states have no broad income tax, and a few like Washington apply a separate capital gains tax above a threshold.
