How Does Owning an S Corporation Affect My Personal Tax Return?
Owning an S corporation can affect Form 1040 through W-2 wages, K-1 items, basis, health insurance, estimated tax and distributions.
How it works
The rule, and what it turns on.
Shareholders generally report allocated income whether or not cash is distributed, and losses can be limited by basis/at-risk/passive rules.
Example
$60,000 W-2 plus $40,000 K-1 income both affect the 1040; a $25,000 distribution is analyzed separately under basis rules.
Common mistakes
What we see go wrong, and what we do instead.
- Equating K-1 income with cash distributions.
- Ignoring Form 7203.
A better approach
- Coordinate corporate and individual returns in the same year-end process.
