Expert Tax Filing and Planning for Independent Professionals, Freelancers, and Small-Business Owners

If you operate your own business or earn income as an independent contractor, your taxes are more complex than a standard W-2 filing.
 At Premier Tax & Resolution LLC, we specialize in Schedule C preparation for self-employed individuals across Oregon and Washington, ensuring every deduction is documented, every form is accurate, and every opportunity to reduce taxes is identified.

Who Files
Schedule C?

If you receive 1099-NEC or 1099-K forms, or run any business not incorporated as a partnership or corporation, Schedule C is part of your federal Form 1040 return.

Schedule C (Profit or Loss from Business) is required for:

Sole proprietors and single-member LLCs not taxed as S-Corps
Gig-economy and contract workers (Uber, DoorDash, consultants, creatives, etc.)
Freelancers, online sellers, and independent professionals
Side-business owners with supplemental income

Comprehensive Rental Property Tax Services

Our Schedule E preparation includes:

Federal Form 1040 + Schedule E and applicable state returns
Income and expense reconciliation for each property
Depreciation calculation and asset basis adjustments
Passive-activity loss and at-risk limitation tracking
Allocation of shared expenses for multi-property owners
Support for short-term rental and vacation-home rules

We use proven systems to organize your data, from 1099s and rent rolls to property-management statements, so nothing is missed.

Maximizing Deductions and ROI

Every property is different, but nearly all landlords can benefit from deductions such as:

Mortgage interest and real-estate taxes
Repairs, maintenance, and supplies
Utilities and HOA fees
Insurance premiums
Professional management fees and commissions
Travel and mileage for property visits
Depreciation on buildings and improvements

We help you document and categorize expenses correctly, reducing taxable income while maintaining full IRS compliance.

Short-Term and Vacation Rental Expertise

If you host on Airbnb or VRBO, we’ll help you navigate:

Rental vs. personal-use days calculations
Local lodging-tax reporting requirements
Passive vs. non-passive income classification
Depreciation of furnishings and equipment

Properly classifying your short-term rental activities ensures you remain eligible for deductions and minimizes exposure to unexpected audits or penalties.

Multi-State and Local Compliance

Owning property in Oregon or Washington often means filing additional state or local forms. We assist with:

Oregon CAT (Corporate Activity Tax) for high-revenue sole proprietors
Washington B&O Tax and city-level licensing compliance
Local-tax filings for Portland, Multnomah County, and Vancouver WA

Our dual-state knowledge ensures you’re correctly registered, reported, and optimized.
