With vs. Without Deductions — Tax Impact
What this calculator means+
Formula and example
Home Office = sq ft × $5 (max $1,500) + Equipment + Travel + Health Insurance + Retirement = Total Deductions. Taxable Income = Income − Total Deductions. Tax Savings = Total Deductions × Marginal Rate.
$80,000 freelance income, 150 sq ft home office = $750, $3,000 in equipment, $3,350 in mileage, $6,000 in health insurance, $5,000 in retirement: total deductions = $18,100. Taxable income drops to $61,900. At an estimated 24% marginal rate, that's $4,344 in tax savings — money you keep by claiming what you're already spending.

Industry-specific deductions — What you might be missing
What tax deductions can tech / software freelancers claim?+
Many devs and IT contractors miss these: Cloud infrastructure (AWS, DigitalOcean, Vercel), IDE and tool subscriptions (JetBrains, VS Code extensions, Postman), SSL certificates and domain fees, API keys and SaaS subscriptions, AWS/Azure certification exams, co-working space for team meetings, and home internet (pro-rated for business use). Keep receipts for all of them — the IRS expects documentation.
What tax deductions can creative / design freelancers claim?+
Creative professionals have unique deductions: Camera and equipment rentals (you don't need to buy — leasing is fully deductible), stock photo subscriptions (Adobe Stock, Shutterstock), portfolio hosting (Squarespace, Adobe Portfolio), studio space rental, art supplies and samples, printer ink and photo paper, domain and portfolio CMS costs, and even Wacom tablets or iPads used primarily for work. Design software subscriptions (Adobe CC, Figma, Sketch, Affinity) are 100% deductible.
What tax deductions can consultants and coaches claim?+
Consultants and coaches leave thousands on the table: Client meals are 50% deductible — yes, that coffee meeting counts. Certification renewals and continuing education courses, online course platform subscriptions (Teachable, Thinkific, Kajabi), co-working day passes (WeWork, local spaces), books and industry publications, professional liability insurance, phone and internet (percentage of business use), CRM software, and conference tickets (including travel if the primary purpose is business). Keep a log — "I met Client X at Y Cafe on Z date" is enough.
What tax deductions can e-commerce / retail sellers claim?+
E-commerce sellers have expenses most employees don't: Inventory storage costs (warehouse rent, shelving, bins), shipping supplies (boxes, tape, bubble wrap, poly mailers), marketplace fees (Etsy listing fees, Amazon FBA fees, Shopify transaction fees), packaging samples and prototyping materials, product photography equipment and studio setups, commercial liability insurance, business licenses and permits, and return/shipping loss write-offs. The cost of goods sold (COGS) is already above-the-line — these are the extras that add up.
Methodology & assumptions
Last updated: 2026-06-25Calculation method
Estimates 5 major self-employed deductions: (1) Home office — simplified method at $5/sq ft (max 300 sq ft); (2) Equipment & software — 100% deductible in year of purchase; (3) Travel & mileage — IRS standard rates; (4) Health insurance — 100% above-the-line deduction; (5) Retirement contributions — SEP IRA or Solo 401(k). Tax savings estimate uses your marginal rate (assumed from income bracket). Does not include meals, continuing education, Section 179, or QBI deduction.
Data sources
Uses the numbers you enter and standard IRS deduction rules for self-employed individuals. Home office simplified method ($5/sq ft) per IRS Publication 587. Mileage rate based on 2026 IRS standard business rate. Health insurance deduction per IRS Section 162(l). Retirement contribution limits per IRS Publication 560.
Limitations
Uses simplified home office deduction — not the actual expense method, which may yield a larger deduction. Mileage assumes standard rate; actual vehicle costs may differ. Does not include Section 179 depreciation, bonus depreciation, meals (50%), continuing education, or the QBI deduction (20% of qualified business income). Consult a CPA for your specific situation. These are educational estimates, not tax filing numbers.
