Question 1

What is Form 8949?

Accepted Answer

Form 8949 reports sales and exchanges of capital assets. Lists each transaction: description, date acquired, date sold, proceeds, cost basis, gain/loss. Separates short-term (held less than 1 year) and long-term (held more than 1 year) transactions. Totals flow to Schedule D. Required for stock, bond, mutual fund, real estate, crypto sales. Brokerage 1099-B provides transaction data for Form 8949.

Question 2

How do I fill out Form 8949?

Accepted Answer

Part I: Short-term transactions (held less than 1 year). Part II: Long-term transactions (held more than 1 year). Enter each transaction: description, acquisition date, sale date, proceeds, cost basis, adjustment code if needed, gain/loss. Calculate totals for each part. Totals transfer to Schedule D lines 1b and 8b. Use 1099-B data from brokerage statements. Software and tax preparers automate Form 8949 preparation.

Question 3

What are short-term vs long-term capital gains?

Accepted Answer

Short-term: Asset held less than 1 year. Taxed at ordinary income rates (10%-37%). Same rate as wages, salary. Long-term: Asset held more than 1 year. Taxed at preferential rates (0%, 15%, 20%). Much lower tax burden. Always try to hold investments over 1 year for long-term treatment. Selling before 1 year triggers short-term rates.

Question 4

How does Schedule D work with Form 8949?

Accepted Answer

Schedule D summarizes capital gains/losses. Line 1b: Short-term totals from Form 8949 Part I. Line 8b: Long-term totals from Form 8949 Part II. Schedule D calculates net gain/loss, combines short and long-term, applies loss limits ($3,000 against ordinary income). Final net capital gain/loss flows to Form 1040 line 7. Schedule D is summary, Form 8949 is detail.

Question 5

What if I have capital losses?

Accepted Answer

Capital losses offset capital gains first. Net loss reduces ordinary income up to $3,000 per year ($1,500 married filing separately). Excess loss carries forward indefinitely. Example: $10K loss, $2K gain = $8K net loss. $3K used this year against wages, $5K carries forward. Loss carryforward tracks on Schedule D. Use losses strategically to reduce tax burden.

Question 6

Do I need Form 8949 for every stock sale?

Accepted Answer

Yes, generally. Exception: If 1099-B reports basis to IRS (Box A checked), transactions can be reported directly on Schedule D without Form 8949 (line 1a for short-term, line 8a for long-term). However, most taxpayers use Form 8949 for all transactions. Keeps records organized. Required if basis not reported to IRS or adjustments needed.

Question 7

What are adjustment codes on Form 8949?

Accepted Answer

Adjustment codes modify reported gain/loss: B - basis reported on 1099-B differs from actual basis. C - wash sale disallowed loss. D - short sale gain/loss adjustment. E - multiple transactions aggregated. F - like-kind exchange. G - distribution from partnership. H - other adjustments. See Form 8949 instructions for complete code list. Use when 1099-B data needs correction.

Question 8

How do I report cryptocurrency on Form 8949?

Accepted Answer

Crypto is property, every sale/trade reported on Form 8949. Record: purchase date, cost basis (including fees), sale date, proceeds (minus fees). Track each crypto-to-crypto trade as taxable event. Long-term if held over 1 year. Short-term if less. Crypto exchanges may provide 1099-B, but often incomplete. You must track all transactions yourself. Keep detailed records.

Question 9

Can I group transactions on Form 8949?

Accepted Answer

Limited grouping allowed. Same-day purchases/sales: combine identical transactions. Multiple lots sold together: aggregate if basis reported to IRS. Most transactions reported separately. Cannot group different assets or different holding periods. Keep individual transaction records. Grouping simplifies Form 8949 but not universally allowed.

Question 10

What records do I need for Form 8949?

Accepted Answer

Keep: purchase statements showing date and cost basis, sale statements showing date and proceeds, brokerage confirmation receipts, dividend reinvestment records (DRIP), stock split records, wash sale adjustments, fee/commission records. Records needed for 3 years after filing (6 years if underreported income). Brokerage 1099-B provides much data but verify accuracy. Basis tracking apps help manage records.

Description	Term	Proceeds	Cost	Gain/Loss
Stock A	Long-Term (>1 yr)	$ 10000.00	$ 8000.00	$ 2000.00
Stock B	Short-Term (<1 yr)	$ 5000.00	$ 6000.00	$ -1000.00
ETF C	Long-Term (>1 yr)	$ 15000.00	$ 12000.00	$ 3000.00
