What Is Self-Employment Tax for Denver Freelancers?

As a Denver freelancer, you’re responsible for paying self-employment tax on your net income. This tax covers Social Security and Medicare, the same programs that traditional employees and employers contribute to together. Understanding how this works is essential for Denver freelancer taxes planning.

The self-employment tax rate for 2026 remains 15.3%, consisting of 12.4% for Social Security and 2.9% for Medicare. However, the Social Security portion only applies to income up to the wage base limit, which increased to $184,500 for 2026. This means income above $184,500 is only subject to Medicare tax (2.9%), not Social Security tax.

How to Calculate Your Self-Employment Tax

To calculate your self-employment tax, start with your net income from Schedule C (self-employment income minus business expenses). Multiply by 92.35% (the self-employment tax threshold), then apply the 15.3% rate. For example, if you have $60,000 in net freelance income, your calculation would be: $60,000 × 0.9235 × 0.153 = $8,497 in self-employment tax.

The good news is that you can deduct half of your self-employment tax as an above-the-line deduction when filing your 2026 tax return. This reduces your adjusted gross income (AGI) and your overall tax liability. Many Denver freelancers overlook this deduction, leaving money on the table.

Social Security Wage Base Changes for 2026

The Social Security wage base increased from $176,100 in 2025 to $184,500 for 2026, a 4.8% increase. This means freelancers earning above this threshold will see a benefit. For every dollar earned above $184,500, you only pay 2.9% Medicare tax instead of the full 15.3%.

When Are Your Quarterly Estimated Tax Payments Due in 2026?

As a freelancer, you don’t have an employer withholding taxes from your paycheck. Instead, the IRS expects you to pay estimated taxes quarterly. Missing these deadlines can result in penalties and interest, even if you ultimately owe little or no tax overall.

How to Calculate Quarterly Estimated Payments

To estimate your quarterly payment, calculate your expected annual net income, add self-employment tax, subtract any available deductions, and divide by four. Use IRS Direct Pay or apply for an installment plan if you can’t pay in full.

For Denver freelancers, the safe harbor rule means you can avoid penalties if you pay either 100% of your prior year tax or 90% of your current year tax. If your 2025 tax was $10,000, paying $2,500 quarterly in 2026 would meet the safe harbor, even if your actual 2026 tax is higher.

Best Methods to Pay Estimated Taxes

Denver freelancers can pay estimated taxes using several methods: IRS Direct Pay (free), Electronic Federal Tax Payment System (EFTPS), or credit card (with processing fees). Mark payment dates on your calendar to avoid missing deadlines.

What Deductions Can Denver Freelancers Claim?

One of the biggest advantages of being self-employed is the ability to deduct business expenses. These deductions reduce your taxable income and can save you thousands on your 2026 return. To qualify, an expense must be ordinary and necessary for your freelance business.

Common Deductions for Denver Freelancers

• Home Office Deduction: Deduct a percentage of rent, mortgage, utilities, and insurance based on your office’s square footage. Simplified method allows $5 per square foot (up to 300 sq ft).
• Equipment and Supplies: Computers, monitors, keyboards, software, office furniture, and supplies are fully deductible.
• Internet and Phone: The portion of your internet and phone bills used for business is deductible.
• Professional Services: Accounting, legal, tax preparation, and consulting fees are fully deductible.
• Marketing and Advertising: Website hosting, domain names, social media ads, and business cards are deductible.
• Professional Development: Courses, certifications, conference attendance, and books related to your business.
• Travel and Meals: 50% of meal expenses and actual travel costs for business purposes (mileage at IRS rates).

The key to maximizing deductions is keeping meticulous records. For Denver freelancer taxes, maintain receipts for all expenses, track mileage, and document the business purpose of purchases. The IRS is more likely to audit Schedule C filers, so documentation is critical.

Schedule C and Schedule SE Filing Requirements

When filing your 2026 tax return, Denver freelancers must complete Schedule C (Profit or Loss from Business) and Schedule SE (Self-Employment Tax). Schedule C reports all income and expenses, while Schedule SE calculates self-employment tax. Filing these forms properly ensures you’re taking advantage of all available deductions.

What Are the Major 2026 Tax Law Changes Affecting Freelancers?

The 2026 tax year brings significant changes that benefit Denver freelancers. The One Big Beautiful Bill Act (OBBBA) introduced several provisions that take effect this year, offering new opportunities to reduce your tax burden.

Enhanced Charitable Donation Deduction

Starting in 2026, all taxpayers—including those who don’t itemize—can deduct up to $1,000 in charitable donations if filing single ($2,000 if married filing jointly). This above-the-line deduction doesn’t require itemizing, making it valuable for Denver freelancers who take the standard deduction.

For example, if you donate $2,000 to qualified charities in 2026 and take the $15,750 standard deduction as a single filer, you can deduct an additional $1,000 of donations. This effectively increases your total deductions to $16,750.

Permanent Bonus Depreciation Reinstatement

Freelancers who purchase equipment, software, or other depreciable assets can now take 100% bonus depreciation. This was set to phase out but is now permanently reinstated under OBBBA. If you buy a $5,000 computer in 2026, you can deduct the full amount immediately rather than depreciating it over time.

New Senior Deduction (If Age 65+)

If you’re 65 or older, you can claim an additional $6,000 deduction in 2026 (up to $12,000 if married), provided your modified adjusted gross income is below $75,000 for single filers. This deduction is available whether you itemize or take the standard deduction.

How Should Freelancers Plan for Retirement in 2026?

Retirement planning is crucial for Denver freelancers who don’t have employer-sponsored plans. Contributing to retirement accounts provides immediate tax deductions while securing your financial future. For 2026, several options are available.

Solo 401(k) Plans (Ideal for Freelancers)

A Solo 401(k) allows you to contribute up to $24,500 as an employee deferral in 2026, plus an additional contribution as an employer. This can total up to $72,000 annually. If you’re 50 or older, you can add an extra $8,000 catch-up contribution.

For example, a 40-year-old Denver freelancer with $100,000 in net self-employment income could contribute up to approximately $30,000 to a Solo 401(k)—$24,500 as an employee deferral plus employer contributions. This immediately reduces 2026 taxable income.

SEP IRA Option for Denver Freelancers

A Simplified Employee Pension (SEP) IRA allows you to contribute up to 25% of net self-employment income, with a 2026 maximum of $72,000. It’s easier to set up and maintain than a Solo 401(k) but offers lower contribution limits for higher-income freelancers.

Are There Denver or Colorado-Specific Tax Considerations?

While federal tax rules apply to all freelancers, Denver has specific tax considerations. Colorado imposes a flat 4.4% state income tax on all residents, which applies to your self-employment income alongside federal taxes.

Colorado State Income Tax and Denver Local Tax

Denver doesn’t levy a separate city income tax, but Colorado residents pay state income tax on all income. Denver freelancers earning $50,000 would owe approximately $2,200 in Colorado state income tax in addition to federal taxes. Ensure you’re tracking this liability for quarterly payment planning.

Colorado Conformity with Federal Tax Changes

Colorado generally conforms to federal tax law but makes selective adjustments. Some federal deductions (like the enhanced charitable deduction for 2026) may not be allowed by Colorado, requiring separate state calculations. Working with a tax professional familiar with Denver freelancer taxes ensures compliance.

Frequently Asked Questions

What if I Miss a Quarterly Estimated Tax Payment Deadline?

Missing a quarterly deadline triggers underpayment penalties. However, the safe harbor rule (paying 100% of prior year tax or 90% of current year tax) can help. If you realize you’ve missed a deadline, pay as soon as possible to minimize penalties. Contact the IRS at IRS.gov/payments to arrange a payment arrangement if needed.

Can I Deduct Home Office Expenses as a Denver Freelancer?

Yes, absolutely. You can deduct a percentage of your home expenses if you have a dedicated office space. Use the simplified method ($5 per square foot, up to 300 sq ft) for $1,500 maximum, or calculate actual expenses. Keep documentation of your home’s total square footage and office space dimensions.

How Much Should I Save for Quarterly Estimated Taxes?

A general rule is to save 30-40% of your net income for taxes. This covers federal (10-24%), self-employment (15.3%), and state (4.4% in Colorado) taxes. If you earn $5,000 monthly, save $1,500-$2,000 quarterly. Adjust based on your actual tax calculation using IRS Publication 1040-ES.

Do I Need Professional Help with Denver Freelancer Taxes?

While not required, a tax professional familiar with Denver freelancer taxes can save thousands through deduction optimization and tax planning. DIY tax software works for simple situations, but freelancers with variable income or multiple income streams benefit from professional guidance. The investment often pays for itself through tax savings.

What Records Should I Keep for an Audit?

Keep all receipts, invoices, bank statements, and proof of payment for business expenses for at least three years (IRS standard). Document the business purpose of expenses, especially for travel, meals, and entertainment. Use accounting software to organize records. The IRS may audit Schedule C returns, so good documentation is essential protection.

Are There Special Rules for 1099-NEC vs. 1099-MISC Forms?

Form 1099-NEC reports non-employee compensation from clients, while 1099-MISC reports miscellaneous income. Both must be reported on Schedule C. You should receive these by January 31 from clients who paid you over $600. Reconcile these forms with your own records when filing your 2026 return.

How Does the Income Tax Bracket System Work for Freelancers?

Income is taxed in brackets: 10%, 12%, 22%, 24%, 32%, 35%, and 37% for 2026. For single filers, the brackets are: 10% on first $11,600, 12% on $11,601-$47,150, and so on. Your tax liability depends on your total income after deductions. Higher deductions lower your tax bracket, reducing your overall rate.
