Tax Preparation

(Form 1120-S)

Professional S-Corp Tax Filing for Oregon and Washington Businesses

Running an S Corporation brings powerful tax advantages, but only when your filings are accurate and compliant.

At Premier Tax & Resolution LLC, we specialize in helping small-business owners and shareholders file precise, audit-ready Form 1120-S returns while maximizing legitimate tax benefits.

Accurate, Compliant,
and Stress-Free

Filing as an S Corporation adds layers of complexity, from basis tracking and shareholder distributions to reasonable-compensation requirements.

Our licensed professionals ensure every part of your return aligns with IRS Circular 230 and IRC §1366 rules so you can stay protected year-round.

Our process includes:

  • Preparing and e-filing your Form 1120-S and all state equivalents 
(Oregon / Washington).
  • Reconciling financial statements and owner payroll for compliance.
  • Calculating shareholder basis, loans, and distributions.
  • Preparing Schedule K-1s and ensuring accurate partner reporting.
  • Reviewing prior-year filings for consistency and carry-forward accuracy.

Maximizing S-Corp Advantages

The S Corporation structure can provide major savings when handled correctly. We help you:

  • Determine reasonable compensation for shareholder-employees.
  • Structure distributions to minimize self-employment taxes.
  • Leverage Section 179 and bonus depreciation strategies.
  • Manage QBI (Qualified Business Income) deductions effectively.
  • Avoid double taxation while maintaining compliance with federal and state laws.

State-Level Expertise

Our firm’s dual-state knowledge ensures compliance beyond the federal return:

  • Oregon CAT (Corporate Activity Tax) planning and apportionment.
  • Washington B&O Tax reporting for service- and product-based S-Corps.
  • Local filings for Portland, Multnomah County, and Vancouver WA jurisdictions.
