Kotso Consulting is a licensed CPA firm delivering business tax preparation with the technical rigor and documentation discipline you’d expect from Big Four environments—without the “drop it off and hope” experience common in filing-only shops. If you need reliable federal and state filing, clean workpapers, and a controlled process built to reduce surprises and penalties, this is your baseline tier.
✔️ Accurate filing
✔️ Audit-ready support
✔️ Built for scale
What Is Business Tax Preparation?
Business tax preparation is the process of preparing and filing federal and state business tax returns using finalized accounting records and supporting documentation. Strong tax preparation doesn’t just “submit forms”—it emphasizes technical accuracy, clean classifications, and audit-ready workpaper support so your return is defensible and your compliance posture stays intact.

CPA Firm Advantage
Elite Compliance Is a Strategic Asset
Traditional tax prep often becomes reactive—built from whatever arrives at year-end. Our approach prioritizes clean inputs, defensible support, and a repeatable process that helps you:
reduce exposure to preventable errors and penalties
improve documentation quality for lenders, investors, or future diligence
create consistency year-over-year so filings don’t become a recurring scramble
Monthly Bookkeeping Deliverables
What’s Included in Business Tax Preparation

✔️ Federal business return preparation: 1120 / 1120-S / 1065
✔️ State return preparation (scope-based; multi-state as required)
✔️ Extension coordination (when applicable)
✔️ Workpaper and support documentation discipline for key positions
✔️ Filing status tracking and confirmation once complete

Business Tax Preparation FAQs
How much does business tax preparation cost?
Tax preparation starts at $1,200. Multi-state filing and complex entities are priced after intake based on footprint, complexity, and records quality.
Do you prepare 1120-S (S-corp) and 1065 (partnership) tax returns?
Yes. We commonly prepare 1120, 1120-S, and 1065 returns. We confirm entity type, ownership, and filing requirements during intake.
Do you handle multi-state business tax filing?
Yes—multi-state filing is scope-based. We confirm where you have filing obligations based on your operational footprint, then prepare the required state returns.
What do you need from my bookkeeper or accountant to file business taxes?
We typically need finalized financial statements plus supporting schedules. If records aren’t stable, we may recommend cleanup/catch-up before final filing to reduce risk.
Do you file extensions for business tax returns?
Yes, when appropriate. Extensions generally extend the filing deadline, but they don’t automatically extend payment obligations. We align timelines and expectations during intake.
How long does business tax preparation take?
Timing depends on record readiness, complexity, and multi-state scope. After intake, we set a clear timeline and milestones so you know what to expect.
Can you file business taxes if our books are behind?
Sometimes—but it depends on how far behind and what’s missing. If records are unreliable, we may scope cleanup support or coordinate with your accounting provider first.
What does “audit-ready” tax preparation mean?
Audit-ready means key positions are supported with consistent documentation and workpapers, prepared with technical discipline so support is easier to produce if reviewed later.
What happens if I receive an IRS or state notice after filing?
If a notice arrives, we can scope response and representation support under IRS Defense, depending on the notice type, timeline, and facts involved.
When should I upgrade from tax preparation to tax planning?
If you’re facing recurring surprises, expanding across states, or want proactive strategy for structure, timing, and estimated payments, planning is typically the better fit than filing-only.
