A parent or relative dies, and somewhere in the estate is a few hundred records, built up over decades, with no receipts and often no memory of what anything cost. You have the Discogs grading knowledge and the eBay account already, so you take on selling it. Then tax season arrives and the obvious question has no obvious answer: what's your cost basis on something nobody bought — at least not by you?
The instinct is to guess at what the original owner paid, or to assume inherited property has no basis at all since it didn't cost you anything. Both are wrong, and the actual rule is better news than either guess.
The rule: basis resets to fair market value on the date of death
Under IRC Section 1014, property acquired from a decedent generally takes a basis equal to its fair market value on the date of death — not the decedent's original cost, and not zero. This is the "stepped-up basis" rule (it works the other direction too, stepping basis down, if the property had lost value by the time of death), and it applies regardless of what the original owner paid or whether they kept a single receipt. A record your father bought for $4 in 1979 that's worth $60 today gets a basis of $60 the moment it passes to you through inheritance — full stop, no connection to that $4 at all.
That's a materially different rule from the one that governs clearing out your own closet, which caps your basis at the lesser of cost or fair market value when you convert personal property to inventory — a rule designed specifically to stop a personal loss from becoming a business deduction. Section 1014 has no such ceiling. An inherited collection can step basis up past what was ever paid for it, and that's not a loophole — it's the statute working exactly as written.
An executor can pick a different date, but almost never will for this
The statute allows an estate's executor to elect an alternate valuation date, six months after death, instead of the date of death itself — but that election is only available when the estate is filing a federal estate tax return, and only when using it lowers both the estate's value and its tax bill. For 2026, the federal estate tax exemption is $15,000,000 per individual, a fixed figure set by the One Big Beautiful Bill Act (with inflation indexing starting in 2027). The estate behind a record collection is almost never anywhere near that number, which means no Form 706 gets filed and no alternate date ever enters the picture — date of death is the only value that exists for basis purposes.
This isn't the same thing as being given the collection while they were alive
If a relative handed you the same collection as a gift while they were still living, none of the above applies. Lifetime gifts fall under IRC Section 1015 instead, which carries over the donor's original basis to you — generally whatever they paid, not the value on the day you received it. A $4 record gifted to you in 2020 still has a $4 basis in your hands today, step-up or not. The date-of-death reset in Section 1014 is specific to property that actually passes through an estate — inheritance, not a gift made before death. If you're not sure which happened, that single fact changes your basis on every item in the box.
What it's worth once it's inventory: ordinary income, not a capital gain
A one-off sale of a single inherited item — say, a nephew who sells his late uncle's complete Blue Note first-pressing a single time and never touches reselling again — is a capital transaction, reported on Schedule D. Gain or loss is measured against the stepped-up basis, and because that basis was set at the date of death, there's usually little gain left to tax if the sale happens soon after.
That's not what's happening once the collection becomes stock in an actual reselling business. Under Section 1221(a)(1), property held primarily for sale to customers in the ordinary course of a trade or business isn't a capital asset — the same exclusion that applies to a closet-clearing sale once it becomes inventory. The stepped-up basis still applies; what changes is where the eventual gain lands. Sell an inherited record through your Discogs or eBay business and any amount above its date-of-death value runs through Schedule C as ordinary income, subject to self-employment tax on top of income tax — not Schedule D, and not capital-gains rates.
Documenting a fair market value nobody wrote down
Most inherited collections never get a formal appraisal, and the IRS doesn't require one for typical reseller-scale inventory — it requires a reasonable, documented estimate made around the time of death, the same standard that applies to establishing basis on items pulled from your own closet. What holds up:
- An estate inventory or probate filing, if one exists — those often
- already list collection values for exactly this purpose.
- Comparable sold listings from around the date of death — Discogs'
- own sold-item history and eBay's completed listings are the most direct
- evidence a reseller has on hand, and the same source [this blog already
- flags as unreliable for current pricing](/blog/discogs-median-price-want-have-resellers-2026)
- works fine here as a historical snapshot rather than a live asking price.
- A per-item allocation of one lump valuation, using [the same
- proportional method used for any purchased lot](/blog/cost-basis-per-item-vs-per-lot)
- — appraise or estimate the collection as a whole, then split that total
- across individual records by relative value, not evenly.
What doesn't hold up: a number estimated at tax time with nothing behind it, assembled from memory months or years after the fact.
A worked example
Say your mother passes away in March, leaving 240 LPs. No appraisal gets done — the estate is well under the federal exemption and no 706 is filed. You research comparable Discogs sales from around that time and estimate the collection's total fair market value at $4,200, then allocate that total across the 240 records by relative value rather than splitting it evenly ($17.50 each would badly overstate the cheap ones and understate the rare pressings).
A mid-tier soul record gets allocated $35 of that $4,200 as its basis. You list it eight months later and it sells for $48. Basis is $35 — not the $6 your mother might have paid for it at a record store in 1976, and not $0. Gain is $13, reported as ordinary income on Schedule C, same as any other sale in your inventory. If that same record had instead sold for exactly $35, there'd be no taxable gain at all — the step-up already did its job before you ever listed it.
What this doesn't settle
- Whether any of this applies to jointly owned property, trust
- distributions, or a collection you inherit alongside siblings as
- co-owners. Those situations layer additional rules (community property
- treatment, how co-owned basis splits) on top of Section 1014 that depend
- on your state and the specific instrument — not something to extrapolate
- from this post.
- State inheritance or estate tax. A handful of states (not currently
- including anywhere resale-heavy tax content on this blog has covered
- federally) levy their own inheritance tax separate from the federal
- estate tax exemption — check your state's rule rather than assuming the
- $15,000,000 federal number is the only threshold that exists.
What to actually do
- Confirm it was an inheritance, not a lifetime gift, before you assume
- Section 1014 applies at all — the two rules produce completely different
- basis numbers from the same box of records.
- **Pin down a fair market value estimate dated to the death, not to
- whenever you get around to listing the first item.** An estate filing,
- if one exists, is the strongest evidence; comparable sold listings from
- around that date are the realistic fallback.
- Allocate a lump valuation across items by relative value, the same
- way you'd allocate any purchased lot — not evenly across every record in
- the box.
- **Report sales through your reselling business as ordinary Schedule C
- income**, not capital gains, once the collection is functioning as
- inventory rather than a one-off sale.
PalmFlow logs a cost basis per item from the day you add it to inventory, whatever that basis actually is — inherited, gifted, sourced from a thrift lot, or pulled from your own shelf. It doesn't estimate fair market value or determine which basis rule applies to a given item; that judgment call, and the documentation behind it, is yours to make.

Determining whether property passed by inheritance or lifetime gift, establishing fair market value on a specific date, and any state-level inheritance tax exposure all depend on your specific facts — confirm your basis and reporting approach with a CPA or estate attorney before relying on it, especially for a higher-value collection.
