Why IT Support & Computer Repair Often Owe Taxes
Service Income Without Withholding Adds Up Across Many Clients
An IT tech handling 10–15 small business clients and occasional residential repairs can earn $60,000–$100,000 annually. Each client represents a relatively small income source, but combined, the SE tax and income tax obligation is real and entirely unwithheld.
Parts and Inventory Purchased for Jobs Are Deductible Costs
Replacement drives, RAM, power supplies, cables, and diagnostic tools purchased for client jobs are deductible costs of goods or supplies. Techs who buy parts personally without tracking those costs miss real deductions.
Vehicle Costs for On-Site Service Calls Are Often Not Claimed
IT professionals who drive to client sites — businesses, offices, residences — accumulate significant business mileage. The mileage deduction for on-site service calls can be worth thousands of dollars annually.
Deductions That Matter for IT Support & Computer Repair
The point is not to get aggressive with deductions. The point is to document the real cost of earning your income so you are not paying tax on money you had to spend to do the work.
