Retirement Plan Contributions
Retirement plan contributions are a powerful deduction for self-employed individuals because they reduce your taxable income while building long-term wealth. The IRS allows you to deduct contributions to qualified plans such as Solo 401(k)s, SEP IRAs, and SIMPLE IRAs. For 2026, the contribution limits are adjusted for inflation, allowing you to save more for retirement while lowering your current tax bill.
Calculating Your Net Self-Employment Income
To determine your deductible contribution limit, you must first calculate your net self-employment income. This figure is your total business income minus your business expenses, including the deduction for the self-employment tax itself. You cannot contribute to a retirement plan based on gross income; the calculation must reflect your actual net profit from the business. according to Quarterly Estimated Tax
Choosing the Right Plan Type
Home Office Deduction
The home office deduction is available to self-employed individuals who use a portion of their home exclusively and regularly for business. This deduction covers a percentage of your home expenses, including rent, mortgage interest, utilities, and insurance. You can calculate this deduction using either the simplified method or the regular method, depending on which provides a greater benefit.
The Simplified Method
The Regular Method
The regular method calculates the deduction based on the percentage of your home used for business. If you use 20% of your home for business, you can deduct 20% of your eligible home expenses. This method often yields a higher deduction for larger homes or higher utility costs, but it requires detailed record-keeping of all home-related expenses. You must ensure the space is used exclusively for business to qualify.
Ordinary Business Expenses
Ordinary business expenses are costs that are common and necessary in your specific industry. These include software subscriptions, office supplies, professional development, and marketing costs. The IRS requires that these expenses be both ordinary and necessary to be deductible. Tracking these expenses accurately is critical for maximizing your deductions and minimizing your tax liability.
Software and Technology Costs
Technology is a significant expense for most freelancers. You can deduct the cost of software subscriptions, cloud storage, and hardware used for business. If you use a device for both personal and business purposes, you must allocate the cost based on business use. For example, if you use a laptop 80% for business, you can deduct 80% of its cost or depreciation.
Professional Development and Education
Vehicle Mileage Rates
Vehicle mileage is one of the most common deductions for self-employed individuals. For 2026, the standard mileage rate is 72.5 cents per mile for business use. This rate covers the costs of gas, oil, tires, and maintenance. You can use the standard mileage rate or the actual expense method, but you must choose one method for the first year you use the vehicle for business.
Documenting Business Mileage
Standard vs. Actual Expense Method
The standard mileage method is simpler and often more beneficial for high-mileage drivers. The actual expense method allows you to deduct a percentage of your actual vehicle costs, such as gas, insurance, and depreciation. You should calculate both methods to determine which provides the greater deduction. Once you choose a method, you generally cannot switch to the other method for that vehicle.
QBI Deduction
The Qualified Business Income (QBI) deduction is a significant tax benefit for self-employed individuals. It allows you to deduct up to 20% of your qualified business income from your pass-through entity. This deduction is subject to income thresholds and limitations based on your taxable income and the type of business you operate. The QBI deduction can significantly reduce your overall tax liability.
Income Thresholds and Limitations
The QBI deduction is subject to phase-in and phase-out ranges based on your taxable income. For 2026, the thresholds are adjusted for inflation. If your taxable income exceeds the threshold, your deduction may be limited based on your W-2 wages paid by the business and the unadjusted basis of qualified property. Understanding these limitations is crucial for maximizing your QBI deduction.

Business Operating Expenses
Insurance and Liability Coverage
Payroll and Contractor Costs
If you hire employees or contractors, their wages and benefits are deductible business expenses. This includes payroll taxes, health insurance, and retirement plan contributions made on their behalf. You must keep detailed records of all payments to employees and contractors to support your deductions and ensure compliance with employment tax laws.
Health Insurance Premiums
Self-employed individuals can deduct health insurance premiums for themselves, their spouse, and their dependents. This deduction is available even if you do not itemize deductions. The premiums must be for a plan that meets the minimum essential coverage requirements. You can deduct the premiums as an adjustment to income, which reduces your adjusted gross income.
Eligible Coverage and Dependents
You can deduct premiums for medical, dental, and long-term care insurance. The coverage must be for you, your spouse, and your dependents as defined by the IRS. You cannot deduct premiums for coverage that is provided by an employer or that is paid with pre-tax dollars. Keeping records of all premium payments is essential to support your deduction.
Interaction with Other Deductions
The health insurance deduction interacts with other deductions, such as the QBI deduction and the self-employment tax deduction. It is important to calculate the order of deductions to maximize your overall tax benefit. Properly tracking these premiums and understanding their interaction with other deductions is crucial for accurate tax planning.
