Common Deductions for Alabama Freelancers

Alabama freelancers should understand the state's unique deduction rules. **Home office expenses**: Claim dedicated business space using simplified or actual expense method. **Business mileage**: 67 cents/mile for 2025; important for rideshare drivers in Birmingham, Mobile, or Huntsville. **Equipment and supplies**: Computers, cameras, tools, and office supplies are deductible. **Professional services**: Accounting, legal, and tax preparation fees are fully deductible. **Health insurance premiums**: Self-employed individuals can deduct health insurance costs. **Retirement contributions**: SEP-IRAs and Solo 401(k)s provide federal tax savings but verify Alabama treatment. **Important**: Alabama has its own deduction rules that differ from federal—the federal standard deduction doesn't apply directly in AL. Alabama allows its own standard deduction ($2,500 single) OR itemized deductions. Federal self-employment income is reported on Alabama Schedule E, and business expenses from Schedule C reduce your Alabama taxable income. Consult the Alabama Department of Revenue for specific conformity rules.
