Everything an S corp files.

  • 1120-⁠S & state returns

    Federal and state returns, including California and New York, which tax S corps their own way.

  • Stock & debt basis

    Each shareholder's basis tracked every year, so losses and distributions are taxed correctly.

  • Elections & eligibility

    Form 2553 on time, late-⁠election relief when it wasn't, and a check that nothing has broken your election.

  • Reasonable compensation

    An owner salary set from your duties and what the role pays, documented in case it's questioned.

  • C-⁠to-⁠S conversions

    Old C corp earnings and built-⁠in gains tracked, so distributions and asset sales don't bring a surprise tax.

  • Pass-⁠through entity tax

    State PTET elections, made only where they lower your total tax.

Four steps, then it's off your plate.

  1. Send your records

    Last year's 1120-⁠S, payroll reports, and the IRS letter that accepted your election.

  2. We check your salary

    Owner pay reviewed before year end, while payroll can still change.

  3. We file the 1120-⁠S

    Federal and state returns by March 15, with a K-⁠1 and basis schedule for each shareholder.

  4. Your 1040, alongside

    Your personal return starts from the same numbers, so your K-⁠1 flows straight in.

    Profit came in higher than expected this year. Should I raise my salary?

  2. Jazlyne HarristonRivet2:30 PM

    Yes, to about $140K, in line with comparable roles. We'll true it up in December payroll with your health insurance on the W-⁠2, then file your 1120-⁠S by March 15.

    Great. Glad that's settled before year end. Thank you.
