QSBS Reporting Requirements: How to Report Qualified Small Business Stock on Tax Returns

Proper reporting of Qualified Small Business Stock (QSBS) sales and exclusions on your tax return is critical for claiming benefits and avoiding audit issues. While QSBS exclusions reduce taxable income, the transactions must still be properly reported on tax returns.

This page explains how to report QSBS sales and exclusions on federal tax returns, documentation requirements, and important reporting considerations.

General Reporting Requirements

All Sales Must Be Reported

Even though QSBS gains may be excluded from income, all sales of QSBS must be reported on your tax return. The exclusion is claimed by reporting the sale and showing the excluded amount separately.

Form 8949 and Schedule D

QSBS sales are reported on:

• Form 8949 (Sales and Other Dispositions of Capital Assets)
• Schedule D (Capital Gains and Losses)

Form 8949 is used to report individual transactions, and Schedule D summarizes the totals.

Reporting the Sale

Form 8949 Reporting

On Form 8949, report the QSBS sale with the following information:

1. Description of Property: Description of the QSBS sold (e.g., "100 shares XYZ Corp. QSBS")

2. Date Acquired: Date the QSBS was acquired

3. Date Sold: Date the QSBS was sold

4. Proceeds: Amount realized from the sale

5. Cost or Other Basis: Your adjusted basis in the QSBS

6. Code: Use code "Q" in column (f) to indicate QSBS exclusion

7. Adjustments to Gain or Loss: Show the excluded amount as a negative adjustment

Schedule D Reporting

Totals from Form 8949 flow to Schedule D, where:

• Short-term capital gains and losses are reported
• Long-term capital gains and losses are reported
• Net capital gain is calculated
• Excluded amounts reduce the net capital gain

Reporting the Exclusion

Showing Excluded Amounts

The excluded portion of the gain is shown as a negative adjustment on Form 8949 in the "Adjustments to Gain or (Loss)" column.

Example:

• Proceeds: $1,000,000
• Basis: $100,000
• Gain before exclusion: $900,000
• Exclusion (100%): ($900,000) [shown as negative adjustment]
• Gain after exclusion: $0

Code "Q" for QSBS

Use code "Q" in column (f) of Form 8949 to indicate that the Section 1202 exclusion applies.

Partnership Reporting

Partnership K-1 Reporting

If QSBS is held through a partnership:

• The partnership reports the sale on its tax return
• Each partner receives a Schedule K-1 showing their distributive share of:
  • Capital gain from the sale
  • Any Section 1045 rollover information (if applicable)
• Partners report their share on Form 8949 and Schedule D
• Partners apply Section 1202 exclusion rules at the partner level

Section 1045 Partnership Elections

If the partnership makes a Section 1045 election:

• The partnership must notify all partners
• Partners receive information necessary to report deferred gain
• Partners must track basis adjustments in replacement QSBS

Documentation Requirements

Records to Maintain

Maintain comprehensive documentation to substantiate QSBS status, including:

1. Stock Purchase Documents:

   • Stock purchase agreements
   • Wire transfer records or checks
   • Corporate records showing original issuance

2. Corporate Qualification Documents:

   • Corporate representations regarding QSBS qualification
   • Financial statements showing asset levels at issuance
   • Documentation of business activities
   • C corporation status verification

3. Holding Period Documentation:

   • Purchase dates
   • Sale dates
   • Records of any transfers (gifts, inheritances, etc.)

4. Basis Documentation:

   • Original purchase price
   • Adjustments to basis
   • Contributions to capital (if any)

5. Partnership Documents (if applicable):

   • Partnership agreements
   • Schedule K-1s
   • Documentation of partnership interests held

Why Documentation Matters

Proper documentation is critical because:

• The IRS may audit QSBS claims
• You must substantiate that stock was acquired at original issue
• You must prove the corporation qualified as a qualified small business
• You must demonstrate the holding period was met
• You must show that exclusion limits were correctly applied

Section 1045 Rollover Reporting

Partnership Rollovers

If a partnership makes a Section 1045 election:

• The partnership reports the election on its return
• Partners receive information on Schedule K-1
• Partners report deferred gain and basis adjustments
• Partners must track basis in replacement QSBS

Individual Rollovers

If you make a Section 1045 election as an individual:

• Report the sale on Form 8949
• Show deferred gain as a negative adjustment
• Maintain records of replacement QSBS purchased
• Track basis adjustments in replacement QSBS

Per-Issuer Limit Tracking

Tracking Exclusions Per Issuer

You must track excluded gains per issuer because the exclusion limit applies per issuer:

• Track excluded gains from each QSBS issuer separately
• Monitor remaining exclusion capacity per issuer
• Apply limits correctly when selling stock from the same issuer in multiple years

Documentation for Limits

Maintain records showing:

• Excluded gains claimed for each issuer in prior years
• Remaining exclusion capacity per issuer
• Calculation of "10 times basis" alternative limit

State Tax Reporting

State Conformity Varies

Section 1202 is a federal tax provision. State tax treatment varies:

• Some states conform to federal QSBS exclusion rules
• Some states (including California and New Jersey) do not conform
• You may need to report excluded gain as taxable income for state purposes

State Tax Returns

Check your state's tax laws and reporting requirements. You may need to:

• Add back excluded gain for state tax purposes
• Report the full gain on state returns
• Pay state tax on gains excluded for federal purposes

Audit Considerations

Common Audit Issues

The IRS may audit QSBS claims focusing on:

• Whether stock was acquired at original issue
• Whether the corporation qualified as a qualified small business
• Whether holding period requirements were met
• Whether exclusion limits were correctly applied
• Whether active business requirements were met

Reducing Audit Risk

• Maintain comprehensive documentation
• Report accurately and completely
• Use professional tax preparers familiar with QSBS
• Obtain corporate representations where appropriate
• Follow all reporting requirements
