Freelancer Tax Guide 2026: Quarterly Payments & Deductions

Freelancing offers incredible freedom: you set your own hours, choose your clients, and work from anywhere. But that freedom comes with a significant trade-off when tax season arrives. Unlike traditional employees who have taxes automatically withheld from their paychecks, freelancers are responsible for calculating, reporting, and paying their own taxes. If you are new to freelancing or want to make sure you are not leaving money on the table, this guide covers everything you need to know about freelancer taxes in 2026.

Understanding Self-Employment Tax

The biggest surprise for most new freelancers is the self-employment (SE) tax. When you work as an employee, your employer pays half of your Social Security and Medicare taxes (7.65%), and the other half (7.65%) is withheld from your paycheck. As a freelancer, you pay both halves, totaling 15.3% on your net self-employment income.

This 15.3% breaks down as follows:

• Social Security: 12.4% on the first $168,600 of net earnings (2026 wage base)
• Medicare: 2.9% on all net earnings, with no cap
• Additional Medicare: 0.9% on earnings above $200,000 (single) or $250,000 (married filing jointly)

The SE tax is calculated on 92.35% of your net self-employment income (this adjustment accounts for the fact that employers deduct their half as a business expense). You can also deduct the employer-equivalent portion (half of your SE tax) from your adjusted gross income, which reduces your income tax.

Self-employment tax is in addition to your regular income tax. A freelancer earning $100,000 could owe roughly $14,130 in SE tax alone, before any income tax.

Quarterly Estimated Tax Payments

The IRS expects you to pay taxes as you earn income, not just once a year. If you expect to owe $1,000 or more in taxes for the year, you are required to make quarterly estimated tax payments. Missing these payments can result in underpayment penalties and interest charges.

2026 Quarterly Due Dates

• Q1 (Jan 1 - Mar 31): Due April 15, 2026
• Q2 (Apr 1 - May 31): Due June 15, 2026
• Q3 (Jun 1 - Aug 31): Due September 15, 2026
• Q4 (Sep 1 - Dec 31): Due January 15, 2027

How to Calculate Quarterly Payments

There are two safe-harbor methods to avoid underpayment penalties:

• 100% of last year's tax: Pay at least 100% of what you owed last year, divided into four equal payments. If your AGI was above $150,000, this threshold increases to 110%.
• 90% of current year's tax: Estimate your current year's tax liability and pay at least 90% of it in quarterly installments.

Most freelancers find it easiest to estimate their annual income, apply the effective tax rate (income tax + SE tax), and divide by four. If your income is irregular, you can use the annualized installment method to make payments based on actual income received each quarter.

Essential Tax Deductions for Freelancers

Deductions reduce your taxable income, which lowers both your income tax and self-employment tax. Here are the most valuable deductions available to freelancers.

Home Office Deduction

If you use a dedicated space in your home regularly and exclusively for business, you can claim the home office deduction. There are two methods:

• Simplified method: $5 per square foot of your home office, up to 300 square feet (maximum $1,500 deduction).
• Regular method: Calculate the percentage of your home used for business and apply it to actual expenses (rent/mortgage, utilities, insurance, repairs). This often yields a larger deduction but requires more recordkeeping.

Equipment and Software

Computers, monitors, cameras, microphones, software subscriptions, and other tools purchased for your business are deductible. Items over a certain threshold may need to be depreciated over several years, but Section 179 allows you to deduct the full cost of qualifying equipment in the year of purchase (up to $1,220,000 in 2026).

Mileage and Transportation

If you drive for business purposes (meeting clients, going to a coworking space, picking up supplies), you can deduct mileage at the IRS standard rate of $0.70 per mile in 2026. Alternatively, you can deduct actual vehicle expenses (gas, insurance, repairs) proportional to business use. Keep a mileage log with dates, destinations, business purposes, and miles driven.

Health Insurance Premiums

Self-employed individuals can deduct 100% of health insurance premiums (medical, dental, and vision) for themselves, their spouse, and dependents. This is an “above the line” deduction, meaning it reduces your AGI even if you do not itemize.

Retirement Contributions

Contributing to a retirement account is one of the most powerful tax-reduction strategies for freelancers. Options include:

• SEP IRA: Contribute up to 25% of net self-employment income (max $69,000 in 2026). Easy to set up and administer.
• Solo 401(k): Contribute as both employee (up to $23,500) and employer (up to 25% of compensation). Total limit: $70,000 in 2026. Offers a Roth option.
• Traditional IRA: Up to $7,000/year ($8,000 if over 50). Deductibility may be limited if you have a workplace plan.

Other Common Deductions

• Professional services: Accounting, legal, and tax preparation fees
• Education and training: Courses, books, and conferences related to your business
• Marketing and advertising: Website hosting, domain names, business cards, online ads
• Internet and phone: Business percentage of your bills
• Coworking space membership
• Travel expenses: Airfare, hotels, and meals (50% for meals) for business trips
• Business insurance: General liability, professional liability (E&O), cyber insurance

Qualified Business Income (QBI) Deduction

The Section 199A deduction allows eligible freelancers to deduct up to 20% of qualified business income. This is a significant benefit that can reduce your effective tax rate substantially. The deduction is available for pass-through entities (including sole proprietors and single-member LLCs) with taxable income below $191,950 (single) or $383,900 (married filing jointly) in 2026. Above these thresholds, limitations may apply based on your business type, W-2 wages paid, and property held.

Recordkeeping Best Practices

• Open a separate business bank account and credit card
• Use accounting software (QuickBooks Self-Employed, Wave, FreshBooks) to track income and expenses
• Save receipts digitally for all business purchases
• Keep a mileage log for vehicle deductions
• Track time spent in your home office
• Maintain records of all 1099 forms received from clients
• Set aside 25-30% of every payment for taxes

Paying taxes as a freelancer does not have to be stressful.
