Paying the IRS and your state

What Happens If You Don’t Pay Taxes on 1099 Income

Short answerThe IRS already gets a copy of your 1099s. When it catches up, it bills tax on every dollar with no credit for your work costs, plus penalties and interest. Six years can top $150,000.

Checked against IRS guidance, October 2026

Some techs on a 1099 never file and never pay. Nothing happens at first. No letter, no call. That’s what makes it dangerous.

How the IRS knows

Every company that pays you $2,000 or more in a year sends the IRS a copy of your 1099. The IRS already knows what you were paid. It just takes time to catch up, often a few years.

What happens when it does

The IRS writes up a return for you. It’s not a friendly one:

  • It counts every dollar on your 1099s.
  • It gives you no credit for tools, miles, phone or anything else you can’t prove.
  • Then it adds penalties and interest.

What gets added on

Charge How much
Not filing and not paying Up to about half the tax
Interest About 7% a year, and it keeps growing
Fraud (if the IRS says you hid it on purpose) Up to 75% of the tax

What it adds up to

Rough federal numbers for a tech who skips six years:

Paid by companies each year Tax for 6 years With penalties and interest
$72,000 about $89,000 about $155,000
$100,000 about $134,000 about $234,000

Add state tax on top. If the IRS calls it fraud, the higher-paid tech is past $300,000.

How the IRS collects

  • Takes money straight out of your bank account
  • Takes a cut of what the companies pay you, before you see it
  • Puts a lien on your truck or house
  • Keeps any refunds you would have gotten

There’s no time limit. If you never filed for a year, the IRS can come after it any time.

Willfully not filing can also be a crime, up to a year in jail for each year. Hiding income on purpose is worse.

If you’re already behind

It’s fixable, even living check to check, and it’s much cheaper to fix before the IRS finds you. Behind on taxes? Step by step to get caught up.

The easiest fix is never getting there: set aside about a third of every check and pay four times a year. How much to set aside.
