Quick Facts

Individuals (including spouses filing jointly) who sold QSBS and want to claim the Section 1202 gain exclusion.
The form captures the amount of stock sold, the date acquired and sold, the basis, the qualifying period, and the calculated exclusion amount.
Attach Form 8834 to your Form 1040 for the tax year in which the QSBS was sold, typically by the regular April 15 filing deadline (or extended deadline if you filed an extension).
Mail the completed form with your Form 1040 to the IRS address listed in the Form 1040 instructions, or file electronically if your tax software supports Form 8834.
Errors can reduce or eliminate the exclusion, leading to unnecessary tax, interest, or penalties. The IRS cross‑checks QSBS data with corporate filings, so inaccurate dates or amounts are flagged.
1. Gather purchase and sale documents for the QSBS (stock certificates, broker statements, corporate shareholder records). 2. Verify the stock meets Section 1202 criteria (qualified corporation, five‑year holding period, etc.). 3. Complete Part I with stock details, then calculate the exclusion in Part II using the worksheet attached to the form. 4. Transfer the exclusion amount to the appropriate line on Form 1040 and attach Form 8834.

Common confusion points

Holding period vs. calendar year

Taxpayers often count years instead of days

→ Verify exact number of days between acquisition and sale

Qualified corporation definition

Small business does not automatically qualify

→ Review active business and gross asset tests

Exclusion percentage change over time

Different rules for stock acquired before/after 2010

→ Check acquisition date against IRS tables

Adjusted basis adjustments

Stock splits, returns, and reinvestments can alter basis

→ Reconcile with broker statements

Reporting on Schedule D vs. Form 1040 line

Misplacement can cause double counting

→ Cross‑check line references in the instructions
