What is business tax preparation?

Business tax preparation is the preparation and filing of your company's annual income tax returns: Form 1120 for C corporations, Form 1120-S for S corporations, Form 1065 for partnerships and multi-member LLCs, or Schedule C within a personal return for single-member LLCs and sole proprietors. Florida imposes a 5.5% corporate income tax reported on Form F-1120 for C corporations, while S corporations and partnerships generally pass income through to owners. Kingsley Accounting Group prepares the return, delivers the K-1s, and walks you through what drove the number before anything is filed.

Sound familiar?

These are the situations that bring people to this service most often.

Your K-1 arrives on September 12 and your personal return is already late.
Nobody has ever explained why your taxable income differs from your book profit.
You suspect you are missing deductions but have no way to check.
Last year's preparer filed an extension and then went quiet for four months.

What’s included

Every engagement covers the following as standard. Nothing here is an upsell.

  • Federal return preparation: Form 1120, 1120-S, 1065 or Schedule C as applicable
  • Florida corporate income tax return (Form F-1120) where required
  • Schedule K-1 preparation and distribution to every owner, on a committed date
  • Book-to-tax reconciliation so you can see exactly where the two diverge
  • Depreciation and Section 179 optimization, including bonus depreciation elections
  • Qualified Business Income (Section 199A) analysis and supporting calculations
  • Estimated tax calculations for the year ahead, not just a rear-view filing
  • A review call before filing: we explain the return, you approve it, then it goes

How it works

You get a short, business-specific request list, not a generic 40-page organizer. Everything uploads to a secure portal.

Prepare and review

We prepare the return, reconcile book to tax, and Dariel reviews it. Anything unusual gets flagged and discussed, not silently absorbed.

Explain, then file

We walk you through what drove the number and what to do differently next year. You approve, we e-file, and you get the full package.

Frequently asked questions

For calendar-year filers: S corporation (1120-S) and partnership (1065) returns are due March 16, 2026, extendable to September 15, 2026. C corporation (1120) returns are due April 15, 2026, extendable to October 15, 2026. Florida F-1120 is generally due one month after the federal due date. We confirm every date against your specific fiscal year.

Generally no. Florida's 5.5% corporate income tax applies to C corporations. S corporations and partnerships typically pass income through to owners, and because Florida has no personal income tax, that income is often not taxed at the state level at all: one of the genuine advantages of operating here.

No. An extension is an automatic, routine filing and does not increase audit risk. It extends the time to file, not the time to pay, so any tax owed is still due on the original date. A well-prepared extended return beats a rushed one filed on time.

Yes, and we recommend it. When the same firm handles both, the K-1 flows straight through, planning is coordinated across entity and owner, and nobody is waiting on anybody.
