## Answer
Quick Answer When you inherit mineral rights, your cost basis generally “steps up” to the interest’s fair market value on the date of the previous owner’s death — the number that sets your capital gain if you ever sell. Most heirs never document it and default to a zero basis, the worst outcome. Establish date-of-death value now from a dated appraisal, comparable sales, or contemporaneous lease terms, and confirm with a CPA. Not tax advice. Key Takeaways Your cost basis — not the sale price — sets how much of a future sale is taxable; the tax is generally on the gain. Inherited minerals generally get a stepped-up basis: fair market value on the date of death, not what the original owner paid. Rank your evidence of date-of-death value: dated appraisal, comparable sales, lease/bonus terms, court-set figures, production records. Producing interests are valued from discounted income; non-producing from comparable sales and lease terms. An appraisal is worth it for larger interests; for a small fraction, well-kept comparable evidence often does the job. A written purchase offer is dated market evidence worth keeping — but it is not a date-of-death appraisal. Confirm basis with a CPA.

## Frequently Asked Questions
**What is my cost basis in inherited mineral rights?**
Generally the fair market value of the interest on the date the previous owner died — inherited property usually receives a “stepped-up” basis to that date, rather than carrying over what the original owner paid. That figure is what a future capital gain is measured against. How it applies to your situation depends on the estate and current law, so confirm with a CPA. This is not tax advice.

**How do I prove the date-of-death value of my minerals?**
With dated evidence of fair market value around the death: strongest is a professional appraisal dated to that time, then comparable arm’s-length sales nearby, contemporaneous lease and bonus terms, court-set consideration figures, and production records for producing interests. Keep whatever you rely on, with sources and dates, so the figure can be defended.

**Is a stepped-up basis the same for producing and non-producing minerals?**
The step-up rule is the same — basis resets to date-of-death fair market value — but the way you value the interest differs. A producing interest is generally valued from its expected future income discounted to that date; a non-producing interest leans on comparable sales and lease terms for similar acreage. A CPA and, for larger interests, an appraiser can establish the figure.

**Do I need a formal appraisal to set my basis?**
Not always. An appraisal is the cleanest evidence and is usually worth it for larger interests or when a sale is likely, but for a small fractional interest its cost can exceed what it saves — well-kept comparable sales and lease terms may suffice. Your CPA can tell you whether an appraisal is warranted for your interest.

**Can I use a purchase offer as evidence of value?**
A written offer is real, dated market evidence of what a buyer will pay today, and it is worth keeping as a data point and as the transaction record your tax advisor needs. It is not a substitute for a date-of-death appraisal, though — an offer reflects today’s market, not the value on the date someone died. Buckhead Energy provides offers, not tax opinions.
