The IRS allows you to deduct expenses that are "ordinary and necessary" for running your trade or business. An ordinary expense is one that is common and accepted in your industry. A necessary expense is one that is helpful and appropriate for your trade. When you write off an expense, you subtract its cost from your gross business income. This reduces your net self-employment profit, which is the amount subject to both self-employment tax (15.3%) and ordinary federal/state income taxes. Therefore, every dollar written off saves you a percentage of that dollar in taxes, depending on your marginal tax bracket. ## The Mathematics of Tax Savings from Deductions The calculator sums four categories of deductions — home office (based on the percentage of your home's square footage used exclusively for business), business mileage (at the IRS standard rate of $0.67 per mile), internet (70% of your monthly bill, a common business-use estimate), plus any equipment and other expenses you enter directly — then applies a single combined tax rate you provide: $$\text{Total Deductions} = \text{Home Office} + \text{Mileage} + \text{Internet} + \text{Equipment} + \text{Other}$$ $$\text{Tax Savings} = \text{Total Deductions} \times \text{Your Tax Rate}$$ For the "Your Tax Rate" input, most freelancers enter their combined self-employment tax rate (approximately 15.3%, or about 14.13% effective on 92.35% of net earnings) plus their marginal federal and state income tax bracket — for example, 15.3% self-employment tax plus a 15-20% income bracket lands many freelancers around a 28-35% combined rate, though your actual figure depends on your total income and state. ## Common Deductible Expense Categories Freelancers can write off a wide range of operational costs, provided they are business-related. Typical categories include: **Home Office**: A portion of rent, utilities, and internet based on the square footage of a dedicated, exclusive workspace. **Software and Subscriptions**: Monthly or annual SaaS tools, hosting, design software, invoicing platforms, and professional memberships. **Hardware and Equipment**: Laptops, cameras, desks, office chairs, and other devices used for client work. **Travel and Meals**: Business travel lodging and transport, plus 50% of the cost of business meals with clients or while traveling. ## How to Use This Calculator Enter your home office square footage and total home square footage, monthly rent and utilities, monthly internet bill, annual business mileage, equipment purchases, other business expenses, and your combined tax rate. The calculator applies the home-office percentage to rent and utilities, the $0.67/mile IRS mileage rate to your business mileage, and a 70% business-use assumption to your internet bill, adds equipment and other expenses directly, then multiplies the total by your tax rate to estimate tax savings. ## Worked Example: 150 sq ft Home Office, 3,000 Business Miles A freelancer works from a 150 sq ft home office in a 1,200 sq ft home, pays $1,500 monthly rent and $300 monthly utilities, $80/month for internet, drives 3,000 business miles a year, bought $1,200 of equipment, and has $500 in other deductible expenses, at a 25% combined tax rate. Home office deduction: ($1,500 + $300) × 12 × (150 ÷ 1,200) = $2,700. Mileage deduction: 3,000 × $0.67 = $2,010. Internet deduction: $80 × 12 × 70% = $672. Total deductions: $2,700 + $2,010 + $672 + $1,200 + $500 = $7,082. Tax savings at 25%: $7,082 × 0.25 ≈ $1,770.50 — real cash kept out of the tax bill for expenses the freelancer was already paying for. ## Related Calculators Feed your after-tax income into the [freelance rate calculator](/calculators/freelance-rate-calculator) to make sure your billing rate covers taxes and expenses, and track invoicing with the [invoice generator](/calculators/invoice-generator). ## Frequently asked questions ### What is a tax write-off? A tax write-off (or deduction) is an ordinary and necessary business expense that you can subtract from your gross income to lower your taxable net profit. ### How much do tax deductions save me? Deductions save you money by reducing your taxable income. Your actual savings equal the deduction amount multiplied by your combined marginal tax rate (self-employment tax + income tax). ### Can I write off my home office? Yes, if you use a specific area of your home regularly and exclusively for your business. You can use the simplified method ($5 per square foot up to 300 sq ft) or the actual expense method. ### Are business meals 100% deductible? No. Typically, business meals with clients or while traveling are only 50% deductible, and you must document the business purpose and attendees. ### Can I write off my personal cell phone? You can write off only the business percentage of your cell phone bill. If you use your phone 60% for work and 40% for personal calls, you can deduct 60% of the bill. ### What is the self-employment tax rate? The self-employment tax rate is 15.3%, which covers Social Security (12.4%) and Medicare (2.9%) on your net business earnings. ### Do I need receipts for deductions under $75? While the IRS does not require receipts for travel expenses under $75 (except lodging), you must still document the date, amount, location, and business purpose of the expense. ### What is a Schedule C? Schedule C (Form 1040) is the IRS tax form used by sole proprietors and single-member LLCs to report net profit or loss from business activities. ### Can a hobby have tax write-offs? No. Under current tax laws, hobbies cannot claim tax deductions. You must demonstrate a clear profit motive for the activity to qualify as a business. ### What is the difference between a tax deduction and a tax credit? A tax deduction reduces your taxable income, saving you a percentage based on your tax bracket. A tax credit reduces your actual tax bill dollar-for-dollar. ## Related concepts - **Schedule C** — The tax form used by sole proprietors to report business income and expenses. - **Self-Employment Tax** — The 15.3% tax covering Social Security and Medicare for self-employed individuals. - **Ordinary and Necessary** — The IRS standard requiring business deductions to be appropriate, helpful, and common in the industry. ## Related guides - [Freelance Tax Write-Offs: Calculator Guide and Recordkeeping Checklist](https://dothecalculation.com/blog/business/freelance-tax-write-offs-guide) — Estimate freelance business deductions with the DTC calculator, understand home office, mileage, internet, equipment, and other expense inputs, and separate planning math from tax filing advice. ## Related calculators - [HSA Tax Savings Calculator](https://dothecalculation.com/calculators/hsa-tax-savings-calculator) — Estimate federal income tax and FICA tax savings from contributing pre-tax dollars to a Health Savings Account each year. - [Business Valuation Calculator](https://dothecalculation.com/calculators/business-valuation-calculator) — Estimate your business value using practical valuation methods such as earnings multiples and asset-based approaches for buyers or investors. - [Depreciation Calculator](https://dothecalculation.com/calculators/depreciation-calculator) — Estimate annual and accumulated depreciation of business assets using straight-line or declining balance methods for accurate accounting. - [Freelance Rate Calculator](https://dothecalculation.com/calculators/freelance-rate-calculator) — Calculate your ideal freelance hourly and project rates from income goals, expenses, and billable hours to price your work with confidence. - [Operating Margin & EBIT Calculator](https://dothecalculation.com/calculators/operating-margin-calculator) — Calculate gross profit, operating income, operating margin percentage, and gross margin to evaluate your core business profitability. - [Weighted Average Cost of Capital (WACC) Calculator](https://dothecalculation.com/calculators/wacc-calculator) — Estimate Weighted Average Cost of Capital, after-tax cost of debt, and capital weights to evaluate investment and financing decisions. --- _This calculator is for educational and business planning purposes only and does not constitute professional tax, financial, or legal advice.
