You have a very simple tax situation. Many people do not.
In the US, if you just have wage/salary income and an investment account, and you lived the entire year in one state, your taxes are also very simple. You can fill everything out yourself in one evening, or pay $100 to do it with tax preparation software.
But things can rapidly get complicated. Did you move from one state to another during the year? Do you live in one state but work for an employer in a different state? Are there any credits or deductions you're eligible for? Or god forbid you live abroad, at which point you're dealing with double-taxation treaties and the like.
