What Is Form 1120-S?

Form 1120-S is the U.S. Income Tax Return for S Corporations. Unlike C Corporations, S Corporations do not pay federal income tax directly. Instead, income, losses, deductions, and credits pass through to shareholders.

Each shareholder reports their share of income or loss on Form 1040 using Schedule K-1, which the corporation provides. This pass-through taxation avoids double taxation on corporate profits and ensures clarity for shareholders.

Who Must File Form 1120-S?

Any corporation that has elected S Corporation status under IRS rules must file Form 1120-S. Key requirements include:

1. 100 or fewer shareholders

2. Eligible shareholders such as individuals, certain trusts, or estates

3. Only one class of stock

Even if your S Corporation had no income or expenses during the year, filing is mandatory for IRS compliance.

Key Sections of Form 1120-S

Form 1120-S includes several important sections that require accurate bookkeeping and clear reporting:

1. Income and deductions: Report revenue, cost of goods sold, and operating expenses

2. Shareholder allocations: Schedule K details each shareholder’s share of income or loss

3. Balance sheet: Snapshot of assets, liabilities, and equity at year-end

4. Other taxes and payments: Employment taxes or excise taxes, if applicable

Following IRS instructions ensures accuracy and reduces the risk of audits. The official IRS guide for Form 1120-S provides detailed line-by-line instructions.

Filing Deadline for Form 1120-S

The regular filing deadline for Form 1120-S is March 15 for calendar-year corporations. If this date falls on a weekend or federal holiday, the IRS moves the deadline to the next business day.

S Corporations that need more time can file Form 7004 for an automatic six-month extension. Remember, an extension allows extra filing time, not extra time to pay any taxes owed.

Penalties for Late or Incorrect Filing

The IRS charges penalties for late or inaccurate Form 1120-S filings. These penalties are assessed per shareholder for each month the return is late. Even a small S Corporation with 4 shareholders can face significant fines.

Frequent mistakes include missing Schedule K-1s, misreported deductions, or incorrect shareholder allocations. Proper bookkeeping and timely filing can prevent these issues.
