S corporation vs. C corporation: The
similarities
The C corporation is the standard corporation, while the S
corporation has elected a special tax status with the IRS. It gets
its name because it is defined in Subchapter S of the Internal
Revenue Code. To elect S corporation status when forming a
corporation, Form 2553 must be filed with the IRS and all S
corporation guidelines met. But C corporations and S corporations
share many qualities:
- Limited liability protection. Both offer
limited liability protection, so shareholders (owners) are
typically not personally responsible for business debts and
liabilities.
- Separate entities. Both the S corp and C corp
are separate legal entities created by a state filing.
- Filing documents. Formation documents must be
filed with the state. These documents, typically called the
Articles of Incorporation or Certificate of Incorporation, are the
same for both C and S corporations.
- Structure. Both have shareholders, directors
and officers. Shareholders are the owners of the company and elect
the board of directors, who in turn oversee and direct corporation
affairs and decision-making but are not responsible for day-to-day
operations. The directors elect the officers to manage daily
business affairs.
- Corporate formalities. Both are required to
follow the same internal and external corporate formalities and
obligations, such as adopting bylaws, issuing stock, holding
shareholder and director meetings, filing annual reports, and
paying annual fees.
S corporation vs. C corporation: The
differences
Despite their many similarities, S corporations and C
corporations also have distinct differences.
- Taxation. Taxation is often considered the
most significant difference for small business owners when
evaluating S corporations vs. C corporations.
- C corporations. C corps are separately taxable
entities. They file a corporate tax return (Form 1120) and pay
taxes at the corporate level. They also face the possibility of
double taxation if corporate income is distributed to business
owners as dividends, which are considered personal income. Tax on
corporate income is paid first at the corporate level and again at
the individual level on dividends.
- S corporations. S corps are pass-through tax
entities. They file an informational federal return (Form 1120S),
but no income tax is paid at the corporate level. The
profits/losses of the business are instead “passed-through” the
business and reported on the owners’ personal tax returns. Any tax
due is paid at the individual level by the owners.
- Personal Income Taxes. With both types of
corporations, personal income tax is due both on any salary drawn
from the corporation and from any dividends received from the
corporation.
- Corporate ownership. C corporations have no
restrictions on ownership, but S corporations do. S corps are
restricted to no more than 100 shareholders, and shareholders must
be US citizens/residents. S corporations cannot be owned by C
corporations, other S corporations, LLCs, partnerships or many
trusts. Also, S corporations can have only one class of stock
(disregarding voting rights), while C corporations can have
multiple classes. C corporations therefore provide a little more
flexibility when starting a business if you plan to grow, expand
the ownership or sell your corporation.
S corporation (S corp) election
To become an S corporation, you must file Form 2553 with the
IRS. The IRS instructions—which can be a bit tough to
follow—require that an election is considered effective in the
current tax year only if the Form 2553 is completed and filed:
- Any time before the 16th day of the 3rd month (for calendar
year tax payers, this means it needs to happen by March 15th)
- Any time during the preceding tax year (however, an election
made no later than 2 months and 15 days after the beginning of a
tax year that is less than 2½ months long is treated as timely for
that year).
Generally, an election made after the 15th day of the 3rd month
but before the end of the tax year is effective for the next tax
year (unless you can show failure to file on time was due to
reasonable cause).
Keep in mind that some states also require you to file a
state-level S corporation election after incorporating your
business.
