Tax season opens! Do you have to file taxes? Why you may want to even if you don't.

Not everyone is required to file taxes, but most Americans must and likely will submit a return. Some will even do so today, the first day the IRS is accepting and processing returns this tax season.

Then, there are those who don't have to file taxes but may want to anyway. Certain benefits can come from filing taxes, believe it or not. You can claim tax credits and overpayments that could result in money being returned to you.

Of the 176.2 million individuals and married couples who could file a return in 2020, about 144.5 million of them did, according to the nonpartisan Washington think tank the Tax Policy Center.

Whether you need to file usually depends mostly on your income, filing status and age.

In special situations, you may have to file regardless of your income. If you have net earnings of at least $400 from self-employment, for example, you’re required to file taxes. If you earn at least that much, you pay self-employment tax.

Important things: When does tax filing season start? Here's when the IRS will start processing returns

What is the minimum income to file taxes in 2025?

To determine if you’re one of the millions who have to file a return, start with three things: Your gross income – total income before taxes and adjustments – and your age and filing status.

Filing status means whether you’re single; married filing jointly or separately; head of household; or a widow(er).

Depending on your age and filing status, the IRS has minimum income thresholds that determine whether you must file a tax return. Here are the breakdowns:

Single filing status: 

◾ $14,600 if younger than 65.

◾ $16,550 if 65 or older.

Married filing jointly: 

◾ $29,200 if both spouses are younger than 65.

◾ $30,750 if one spouse is younger than 65 and one is 65 or older.

◾ $32,300 if both spouses are 65 or older.

Married filing separately:

◾ $5 for all ages.

Head of household: 

◾ $21,900 if younger than 65.

◾ $23,850 if 65 or older.

Qualifying widow(er) with dependent child: 

◾ $29,200 if younger than 65.

◾ $30,750 if 65 or older.
