  • You have multiple owners or want to bring in investors easily

When an S-Corp Makes More Sense

  • Your business generates over $60,000 in annual profits consistently
  • You want to minimize self-employment taxes on business distributions
  • You're comfortable with payroll requirements and corporate formalities
  • You have a single owner or small group of US citizen shareholders

Tax Deep Dive

Llc Default Tax

Connecticut LLCs are taxed as pass-through entities by default, meaning all business profits flow to your personal tax return. You'll pay self-employment tax (15.3%) on the entire profit amount, plus Connecticut's business entity tax with a $250 minimum.

S Corp Tax

S-Corps split income into salary (subject to payroll taxes) and distributions (not subject to self-employment tax). You must pay yourself a reasonable salary, but additional profits can be distributed tax-free at the federal level, though Connecticut still imposes its entity tax.

Breakeven Income

In Connecticut, S-Corp election typically becomes worthwhile around $60,000 in annual business profits, where the self-employment tax savings offset the additional payroll and compliance costs.
