Common Deductions for New Jersey Freelancers
New Jersey freelancers should maximize deductions to reduce their progressive state tax burden. **Home office expenses**: Claim dedicated business space using simplified ($5/sq ft) or actual expense method—valuable given NJ's high housing costs. **Business mileage**: 67 cents/mile for 2025; important for those traveling to client sites across the state or into NYC. **Equipment and software**: Computers, professional tools, and business software; Section 179 allows immediate expensing. **Professional services**: Legal, accounting, bookkeeping, and tax preparation fees are fully deductible. **Health insurance premiums**: Self-employed individuals can deduct 100% of health insurance costs. **Retirement contributions**: SEP-IRAs and Solo 401(k)s reduce both federal and NJ taxable income. **Marketing and advertising**: Website costs, business cards, and promotional materials qualify. **Phone and internet**: Claim the business-use percentage of monthly bills. New Jersey follows federal AGI calculations closely, so most federal deductions automatically reduce your NJ taxes. However, verify NJ treatment of specific items like bonus depreciation with the NJ Division of Taxation.
