Many people think “filing taxes” means “paying taxes.” But in reality, you have been paying taxes all year if you are working as an employee (every time you get a paycheck, taxes are being withheld).
Filing your return (Form 1040) is just a reconciliation process. It means you and the government compare notes to see if you paid the correct amount. The entire process comes down to one simple equation:
Total Tax Owed − Taxes Already Paid = Final Result (Refund or Due)
- The Refund: If you paid more during the year than you actually owed, the government (IRS) sends you the difference as a refund check.
- Amount Due: If you paid less during the year than you owed, you must write the IRS a check for the difference, which may also include an underpayment penalty.
Even if you owe nothing or are owed a refund, you have to file a return to settle the account. For the IRS to send you a refund, you have to ask (file) for it.
The cleanest way to make the refund vs. due equation zero out is to fill out your W-4 as accurately as possible when you start a new job.
