S-corporation tax services for Indiana small business owners — corporate documents reviewed by a CPA

When should an Indiana business elect S-corp status?

Roughly: when net profit (after a reasonable salary to the owner) exceeds about $40k–$50k. Below that, the S-corp tax savings don't cover the additional payroll and tax-prep costs. Above it, the savings compound — typically $3k–$15k+ per year of FICA savings on the distribution portion of owner compensation.

The election (Form 2553) must be filed within 2 months and 15 days of the start of the tax year you want it effective; late-election relief exists but is conditional. We handle the timing and filing.

How does Indiana tax S-corporations?

Indiana doesn't impose a separate S-corp income tax — income passes through to the shareholders' Indiana IT-40 returns. There's a $250 annual minimum corporate fee. S-corps with nonresident shareholders may file a composite return paying Indiana tax on their behalf. The 2026 Indiana flat tax rate is 2.9%, which affects pass-through math significantly.

What is reasonable salary and why is it the most-audited S-corp issue?

S-corp owners can take part of their compensation as salary (subject to FICA / Medicare) and part as distributions (not subject to FICA). The IRS audits this aggressively because too-low salary equals lost payroll tax. Reasonable salary must reflect what you'd pay someone else to do your job — documented with comparable-position data, hours, and duties.

We do a written reasonable-comp study annually with BLS data, the Bureau of Labor Statistics, and industry-specific surveys. The result is defensible documentation — not just a number we pick.

Can a single-member LLC be an S-corp?

Yes. The LLC is the legal entity; the S-corp is the tax election. We file Form 8832 (if needed) and Form 2553 simultaneously so a single-member LLC files as an S-corp federally and pass-through in Indiana. The LLC's operating agreement and Indiana INBiz registration don't change.

What's included

  • S-election. Form 2553 prepared, late-election relief if needed, Indiana INBiz coordination.
  • Reasonable salary study. Documented methodology — BLS comparables, hours, duties — defensible if audited.
  • 1120-S preparation. Federal and Indiana IT-20S with K-1s for shareholders, on time.
  • Basis tracking. Stock and debt basis maintained shareholder-by-shareholder, year-over-year.
  • Distributions vs. salary modeling. Annual Q4 modeling — and quarterly updates if material change.

Common questions

S-Corp Tax Services — questions we get

I'm a Schedule-C filer with $100k profit. Should I elect S-corp?
Almost certainly worth modeling. At $100k profit, S-corp typically saves $5k–$8k/year in FICA after accounting for added payroll, tax prep, and reasonable-comp obligations. We'll run the math before you decide.
What if I missed the S-election deadline for this year?
Late-election relief (Rev. Proc. 2013-30) lets you file an S-election up to 3 years and 75 days late with a reasonable-cause explanation. We've gotten dozens of late elections approved.
How often should reasonable comp be reviewed?
Annually, in Q4. Comp set in year one stops being defensible if profit doubles in year three. Annual review with documentation closes the audit risk.
Do you handle the Indiana IT-20S?
Yes — federal 1120-S + Indiana IT-20S filed together, with K-1s and IT-65/IT-40 coordination for shareholders.
What's a composite return and do I need one?
An Indiana composite return is filed by the S-corp on behalf of nonresident shareholders so they don't have to file their own Indiana return. Required for most nonresident S-corp shareholders.
Should I have an Accountable Plan for my S-corp?
Yes if you reimburse yourself for business mileage, home office, or other personal-pay business expenses. We set up an Accountable Plan as part of S-corp onboarding so reimbursements aren't taxed.
