The Grayscale Bitcoin Trust (GBTC) is one of the most widely held cryptocurrency investment vehicles, especially among investors who prefer exposure to Bitcoin through traditional brokerage accounts. However, when tax season arrives, many filers are unsure how to report GBTC transactions accurately on TurboTax. This guide breaks down everything you need to know—from tax treatment and cost basis reporting to navigating TurboTax’s crypto section and understanding regulatory nuances.
Understanding GBTC and Its Tax Implications
GBTC is a grantor trust that holds Bitcoin and issues shares traded on public markets. Unlike direct Bitcoin ownership, GBTC shares are treated as non-covered securities by the IRS. This means your broker may not report the original cost basis on Form 1099-B, placing the responsibility on you to track and report it accurately.

How Is GBTC Treated for Tax Purposes?
When you sell or redeem GBTC shares, the transaction is a taxable event. The proceeds are reported on Form 1099-B, but since GBTC is a non-covered security, the IRS does not receive cost basis data from your broker. You must manually report your original purchase price and holding period on Form 8949, which then flows into Schedule D of your Form 1040.
Capital gains are categorized as:
- Short-term: Held for one year or less (taxed at ordinary income rates)
- Long-term: Held for more than one year (eligible for lower capital gains rates)
Is GBTC Considered Virtual Currency?
No. Despite being a Bitcoin-backed investment, GBTC is not classified as virtual currency by the IRS. It is treated as a stock-like security. This distinction matters because virtual currency transactions (like direct Bitcoin trades) have different reporting rules in TurboTax compared to stock or trust sales.
Because GBTC is not crypto per se, you’ll report it under the stock and investment section, not the cryptocurrency section of TurboTax.
Reporting GBTC Fees and Transactions in TurboTax
How Do I Report GBTC Fees on TurboTax?
Transaction fees related to buying or selling GBTC can be added to your cost basis (for purchases) or subtracted from proceeds (for sales), reducing your taxable gain or increasing your deductible loss.
In TurboTax:
- When entering a sale, look for the option to adjust cost basis or sale proceeds.
- Include any commissions or fees paid during the transaction.
- This ensures accurate capital gain/loss calculation.
How Do I Enter Crypto or Investment Transactions in TurboTax?
Although GBTC isn’t crypto, many investors hold both. Here’s how to report investment transactions:
- Log in to TurboTax Online and select Premier or Self-Employed (required for investment reporting).
- Answer initial prompts until you reach “I Sold Stock, Crypto, or Other Investments.”
- Choose Stocks, Mutual Funds, Bonds, and Other Investments.
- Enter your 1099-B details manually or via import.
- For non-covered securities like GBTC, TurboTax will prompt you to enter cost basis information.

Key Regulatory Questions About GBTC
Is GBTC Regulated by the SEC?
Yes. GBTC is an SEC-reporting company, making it one of the few crypto-related investment trusts with regulatory oversight. It files regular reports (10-K, 10-Q) with the Securities and Exchange Commission.
This transparency adds investor protection but doesn’t change tax treatment.
Is GBTC Approved by the SEC as an ETF?
No. The SEC has denied Grayscale’s application to convert GBTC into a spot Bitcoin ETF—though this could change in the future. Currently, GBTC operates as a closed-end fund, which can trade at a premium or discount to its net asset value (NAV).
What Happens When GBTC Becomes an ETF?
If GBTC transitions to an ETF:
- Arbitrage mechanisms would align share price with NAV
- Trading discounts could shrink
- Tax reporting may become more standardized
- Liquidity and investor access would likely improve
Until then, investors must manage premiums/discounts and manual tax reporting.
Cost Basis and Tax Compliance
Why Is Some Cost Basis Not Reported to the IRS?
For non-covered securities like GBTC purchased before 2012 (the start of IRS cost basis reporting), brokers aren’t required to report your original cost. You must keep your own records.
If you lack documentation:
- Use brokerage statements
- Reconstruct purchases using trade confirmations
- Consider using financial history tools
Failure to report cost basis can result in the IRS taxing the entire sale amount as gain.
How Is GBTC Premium Calculated?
The premium (or discount) is the difference between:
- Market price per share
- Net asset value (NAV) per share
Formula:
Market Price = NAV + Premium (or – Discount)
Premiums occur due to supply and demand. For example, if GBTC trades at a 5% premium, you’re paying more than the underlying Bitcoin value.
While this affects investment returns, it doesn’t directly impact taxes—only your cost basis and sale proceeds do.
Common Crypto Tax Questions
Do I Have to Report Every Crypto Transaction?
Yes. The IRS requires reporting of all taxable crypto events, including:
- Sales for fiat
- Trades between cryptos
- Payments for goods/services
- Mining or staking income
Even small transactions must be reported if they generate gain or income.
How Much Crypto Income Must Be Reported?
You must report crypto activity regardless of amount. There is no minimum threshold. Even $1 in gains must be declared.
Note: A Form 1099-K may be issued if you have over $20,000 in payments and 200+ transactions—but this doesn’t exempt smaller activities from reporting.
Frequently Asked Questions
Can I use TurboTax Free Edition for GBTC?
No. TurboTax Free Edition doesn’t support stock sales or investment income. Use TurboTax Premier instead.
Should I report GBTC under crypto or stocks in TurboTax?
Report GBTC under stocks and investments, not cryptocurrency, because it’s a securities trust, not direct virtual currency.
What if I can’t find my GBTC purchase records?
Reconstruct your cost basis using:
- Brokerage account history
- Annual statements
- Tax records from prior years
If necessary, consult a tax professional.
Does holding GBTC trigger taxable events annually?
No. Simply holding GBTC is not taxable. Only selling or redeeming shares creates a taxable event.
How do I add Form 8949 to TurboTax?
TurboTax automatically generates Form 8949 when you enter investment sales. Just ensure you input correct cost basis and date acquired for each transaction.
Can I claim a loss if GBTC is trading below my purchase price?
Yes. Capital losses from selling GBTC can offset other capital gains. Up to $3,000 in net losses can be deducted against ordinary income annually; excess carries forward.
