What are back taxes?

What are back taxes?

Back taxes are taxes that are delinquent or overdue, typically from previous years. The IRS begins to charge penalties and interest on late or unpaid taxes the day after the tax filing deadline for that year. If the bill remains unpaid, notices will follow, and the agency may eventually begin other collection measures.

If the bill remains unpaid, notices will follow, and the agency may eventually begin other collection measures.

The IRS typically doesn't charge penalties or fees on late or unfiled tax returns that result in a refund. However, there are many reasons why people in this group should consider filing their prior-year tax returns. For starters, you can't collect your refund until you file, and if you don't file within three years of the tax deadline for that year, you forfeit your right to collect the funds

If you don't file a return by the tax day of the year it's due (typically in mid-April), you'll be subject to a late-filing penalty. On top of that, any taxes you owe after the filing deadline passes will begin to amass fees in the form of penalties and interest. The IRS will usually inform you that you're in delinquency by sending notices and bills to the address on file for you. If those bills are ignored, the agency will ramp up the collection process by assessing a tax lien and eventually a tax levy.

This is called a substitute return. The IRS takes the information it has on hand for you, uses it to file a tax return on your behalf, and sends you the bill. That may sound convenient, but it's almost always a guaranteed headache. In addition, the IRS often won't factor in any tax deductions or tax credits you might have qualified for, leading to a bill higher than what you might've had if you'd done it yourself.
