For the purpose of US Federal income tax, if your income was enough that WITHOUT any deductions, you COULD owe $0.01, you are legally required to file a tax return. If you are not otherwise required to file, but had $1.00 in withholding, you SHOULD file a return to claim your refund. As long as you have a social security number or taxpayer identification number, you

CAN file a return.

You have to file if you had income over a certain amount even if you don't owe.

You can't be serious. There is no way anyone would really ask that. The deadline was April 17. You know that right?

If you owe money, are owed money, or you estimated perfectly, you still file your taxes with the Federal, State and perhaps local governments.

There is only one reason to file if you don't owe and your income is below the filing requirement, and that is when tax was withheld from your income and you want it refunded. You must file for it. If you earn more than $12,000 in 2018 as single, $24,000 married filing separately or $18,000 head of household, you must file even if you don't owe tax. If you are not required to file and you had no tax withholding, there is no reason to file. You can file if you want to, but why?

You MUST file a tax return if your taxable income is more than the personal exemption plus standard deduction, even if you will claim enough other credits to reduce your tax to zero.

You MAY file a tax return if your taxable income is below that limit but you paid income tax, since you are due a refund.

Waiting a year would just make your tax return a year late, it wouldn't have any effect on the numbers. And after 3 years you can no longer claim a refund.

You have to file - to show them that you don't owe them money. If they owe you money, don't you want to receive it?

Yes. And in most cases, you must file. You usually don't even have the option to wait until next tax season.

But even if you don't have to file, you certainly can file. Everyone is allowed to file. There is no one who can't file. There used to be one guy who couldn't file, but that was mainly because he was being held hostage by terrorists who wouldn't let him go where he needed to go to file. When he died, was released, or escaped, the worldwide total number of living humans who couldn't file dropped from one to zero.

The requirement to file taxes is based on the amount of income you earned - not if you owe money or not.

You file a tax return to determine if you owe or if you get a refund.

You file a tax return to prove to the IRS that you did pay the right amount of taxes for your tax situation.

Yes, and if you made over a certain amount of income, you are required to.
