Self-Employed Tax Help

Self-Employed Tax Help in Aurora, CO

Clear, organized support for 1099 earners, contractors, and gig workers—so your taxes are accurate, complete, and handled the right way.

1099 Income Is Different From W-2 Income

If you’re self-employed, your tax return is more than entering a W-2. Independent contractors, freelancers, and gig workers must track income, expenses, and quarterly estimated taxes. Mark Christiansen Associates LLC provides self-employed tax help in Aurora CO, with structured support for Schedule C filings and related reporting.


If you’re asking, “I got a 1099—do I need to file quarterly taxes?” the answer often depends on how much you earn and whether taxes are being withheld elsewhere. We review your situation and help determine appropriate estimated payments.

What We Handle for Self-Employed Clients

  • 1099 Tax Preparation

    We report income from 1099-NEC and 1099-MISC forms, along with any direct payments received.

  • Schedule C Tax Help

    Schedule C reports business income and expenses. We help organize deductions and ensure expenses are categorized properly.

  • Quarterly Estimated Taxes

    If required, we calculate quarterly estimated tax payments to reduce penalties and prevent large balances due.

  • Small Business Deductions

    Common deductions may include:


    • Home office expenses
    • Mileage and vehicle use
    • Equipment and software
    • Professional services
    • Health insurance premiums (when applicable)

    Using a structured checklist helps ensure deductible expenses are not overlooked.

Common Questions From Self-Employed Clients

  • Can you help with Schedule C?

    Yes. Schedule C preparation is a core part of self-employed tax returns.

  • What expenses can I deduct as self-employed?

    Deductible expenses must be ordinary and necessary for your business. We review your specific situation to determine which expenses qualify under current tax rules.

  • Do I need to file quarterly taxes?

    If you expect to owe a certain threshold in tax and no withholding covers it, quarterly estimated payments are often required. We evaluate your projected income to determine whether they apply.

Avoid IRS Surprises

Self-employment income increases audit risk if records are incomplete or deductions are not well documented. Organized bookkeeping and clear reporting reduce that risk.
