Unsure where you owe sales or use tax or dealing with legacy compliance pain?

Check Your Exposure

What happens if I do not file sales tax or use tax?

Not filing sales tax or use tax returns can create compounding issues over time, but outcomes vary based on where filing was required, how long returns were missed, and whether tax was owed or collected. Many businesses do not realize filing was required until exposure has already accumulated. The most important first step is understanding where filing obligations actually exist before taking action.

When sales tax and use tax filing is actually required

Sales tax and use tax returns are required only after a business has a filing obligation. Filing obligations typically arise when a business has sales tax nexus or has registered with a jurisdiction.

Not filing is an issue when:

Not filing is not automatically a problem if no filing obligation existed.

What can happen when sales tax or use tax returns are not filed

Penalties

Many jurisdictions impose penalties for late or missing returns. Penalties may be fixed amounts or calculated as a percentage of tax due.

Interest

Interest often accrues on unpaid tax balances over time. Interest continues to accumulate until liabilities are resolved.

Estimated assessments

Some tax authorities issue estimated assessments when returns are not filed. These estimates are frequently higher than actual liability.

Audit and enforcement risk

Missing filings can increase the likelihood of audit notices, collection letters, or enforcement actions, especially when authorities use marketplace, payment processor, or third-party data.

Common misconceptions about not filing sales tax or use tax

Facts matter more than fear.

What makes the situation better or worse

Several factors influence outcomes:

  • How long returns were missed
  • Whether tax was collected but not remitted
  • Whether registration already exists
  • Whether the jurisdiction discovered the issue or the business did
  • Whether corrective steps are taken proactively

These details matter more than the number of missed returns alone.

What not to do first

Many businesses make the situation worse by:

  • Filing returns without understanding exposure
  • Registering in new states without planning
  • Paying estimated assessments without review
  • Taking action based on fear rather than facts

The correct first step is clarity.

How to decide the right compliance steps

A practical approach looks like this:

Step 1

Identify where filing obligations actually exist

Step 2

Determine how many returns may be missing

Step 3

Understand whether tax was owed during those periods

Step 4

Evaluate remediation options calmly

This avoids unnecessary filings and overpayment.
