S-Corp Election in Connecticut
For Connecticut business owners with net income above $50,000, electing S-Corp status can save $5,000 to $20,000+ annually in self-employment taxes. As an S-Corp, you pay yourself a "reasonable salary" and take the remaining profits as distributions, which are not subject to the 15.3% self-employment tax.
Example: Connecticut S-Corp Savings
A Connecticut business owner earning $150,000 in net business income pays themselves a reasonable salary of $60,000. The remaining $90,000 in distributions avoids the 15.3% SE tax, saving $13,770 in self-employment taxes alone — before any additional state-specific savings.
