Partnerships vs. S Corporations: What You Need to Know About Taxes

Pass-Through Taxation for Partnerships and S-Corporations

Both partnerships and S-corporations are considered pass-through entities, which means they don’t pay corporate income tax themselves. Instead, they distribute profits, losses, deductions, and credits to their owners, who report these items on their individual tax returns. But there are key differences in how each is structured, taxed, and reported.

🏢 Partnerships: The Basics

  • A partnership is an unincorporated business owned by two or more individuals.

  • It files IRS Form 1065, and each partner receives a Schedule K-1 showing their share of the profits or losses.

  • The partner reports this K-1 data on their personal tax return.

  • Losses may be deductible but are subject to basis and at-risk limitations.

Audit-Proof It:
Use Zoho Expense to assign each business expense to the appropriate partner or project. Upload receipts, note business purpose, and categorize transactions under tax-compliant tags (like “Meals – 50% deductible” or “Home Office Utilities”). This ensures each K-1 item is documented, traceable, and ready for IRS scrutiny.

🧾 S-Corporations: Tax-Efficient but Structured

  • An S-corp files Form 1120S and distributes a Schedule K-1 to each shareholder.

  • Shareholders report their K-1 income on their personal return.

  • S-corps do not pay corporate-level income tax.

  • Reasonable compensation rules require owners who work in the business to pay themselves a W-2 salary.

Pro Tip for S-Corps:
Track owner draws, payroll disbursements, and fringe benefits (like health insurance) in Zoho Expense. Attach backup docs like payroll stubs and insurance invoices. Tag entries clearly to support reasonable compensation documentation in case of an audit.

🏢📄 C-Corporation vs. Pass-Through: A Quick Note

  • C-corps file Form 1120, pay their own tax, and issue Form 1099-DIV to shareholders if dividends are paid.

  • No K-1s for C-corp shareholders.

  • Result: potential double taxation (corporate level + shareholder level).

📑 Understanding the Schedule K-1

Your K-1 summarizes your share of:

  • Business income (passive or active)

  • Rental income or losses

  • Capital gains, interest, dividends

  • Deductions and tax credits

Use Zoho Expense to mirror the K-1 categories in your chart of accounts. By doing so, reconciliation becomes seamless at tax time, and your CPA can pull audit-ready reports straight from your dashboard.

🚨 IRS Compliance Tips:

  • Retain documentation for all K-1 related items for at least 7 years.

  • Avoid commingling personal and business funds.

  • Maintain a digital trail—Zoho Expense integrates with Zoho Books, syncing transaction metadata with receipt images and tags.
