Why VDAs for Sales Tax Compliance Matters for SaaS Companies

Why voluntary disclosure agreements matter for SaaS companies with past sales tax exposure: reducing penalties, back taxes, and audit risk.

Why VDAs for Sales Tax Compliance Matters for SaaS Companies

This guide explains why VDAs matter for sales tax compliance at SaaS companies. It also shows how they help lower money and legal risks. As SaaS businesses grow, they need to understand and follow sales tax rules. That's how they avoid penalties, audits, and even prosecution. With automation and data checks, companies can report what they owe accurately. They can also keep up as tax laws change.

Why SaaS Companies Should Care About Sales Tax Compliance?

Sales tax compliance matters for SaaS companies because the cost of getting it wrong is high. It can include:

  • Heavy penalties
  • Back taxes
  • Possible criminal prosecution

With help from the Multistate Tax Commission, states watch closely for taxpayers who haven't met their tax duties. That's most true for companies with nexus in many states. (Nexus is the link to a state that means you must collect its tax.)

Ignoring sales tax duties can lead to audits. Audits disrupt your business and hurt your name. SaaS companies that sell in many states must put compliance first to keep running smoothly.

Resources like the California Department of Tax and Fee Administration's (CDTFA) guide to out-of-state sales tax duties show why it's key to understand and meet your tax obligations.

Strong compliance habits help SaaS companies stay safe. When they deal with what they owe early, they can avoid audits, lower penalties, and cut the legal risk of criminal prosecution. That protects their long-term growth and their name.

Kintsugi is the only sales tax compliance company in the world that offers in-house VDAs at no additional cost on our premium plan.

What Is a Voluntary Disclosure Agreement (VDA)?

A Voluntary Disclosure Agreement (VDA) is a formal deal between a taxpayer and a state tax agency. It lets a business come forward on its own about unpaid sales tax, use tax, and other taxes it owes. In return, it gets lower penalties and a limited look-back period (the number of past years the state can collect for).

This process is a big help for SaaS companies that missed tax duties by accident. That often happens when they didn't know they had nexus. It might come from sales in many states.

The VDA process is private. Many states let you disclose without giving your name at first. That protects your sensitive data in the early talks. The Multistate Tax Commission's (MTC) voluntary disclosure programme also makes things easier for companies in many states. You don't have to deal with each state on its own.

A VDA helps you avoid criminal prosecution. It also shows you're serious about compliance. It gives you money relief by lowering penalties and heading off costly audits. In the end, voluntary disclosure agreements let SaaS companies fix past mistakes, limit future risks, and stay in good standing with tax agencies.

How SaaS Companies Benefit from VDAs

For SaaS companies, a VDA offers many benefits:

  • Financial Relief: A shorter look-back period means you owe less for past years. That can save a lot.
  • Reduced Penalties: States often lower penalties when you come forward on your own. That also lowers the risk of criminal prosecution.
  • Confidentiality: The VDA process often keeps your name private during talks. That protects sensitive data and business details.
  • Streamlined Reporting: You can add automation and data-check tools to your compliance process. That makes ongoing reporting faster.
  • Improved Compliance: Coming forward shows you're serious about following the law. It lowers audit risk and builds trust with stakeholders.

Businesses with heavy tax duties gain a lot from the clear structure a VDA offers. For SaaS companies, this means fewer audit disruptions and better control of sales tax rules.

When Should a SaaS Company Consider a VDA?

SaaS companies should think about a Voluntary Disclosure Agreement (VDA) when they find tax duties they haven't met. These gaps could lead to penalties, audits, and even criminal prosecution. A VDA becomes key once you have nexus in a state—through sales, employees, or property—but haven't collected or remitted (paid to the state) sales tax or use tax.

Here are four scenarios when a SaaS company should consider a VDA.

  • Unregistered Sales Tax Nexus in Multiple States – Say a SaaS company has been selling in states where it meets economic nexus thresholds. But it hasn't registered for sales tax. A VDA can lower penalties and limit what it owes for the past.
  • Recent Nexus Discovery During a Tax Compliance Review – Say a company runs a nexus study and finds tax it didn't report. A VDA gives it a clear way to come forward and pay past-due taxes before states start an audit.
  • Before a Merger, Acquisition, or Funding Round – Investors and buyers often check a company's books closely. Unpaid sales tax can delay deals or lower the company's value. A VDA helps clear up past issues and makes the deal go smoother.
  • Failure to Collect Sales Tax on Digital Products and Services – Many SaaS businesses think their products are tax-exempt. But several states tax digital goods and software subscriptions. If you didn't collect the tax, a VDA can help you fix it before penalties pile up.

Voluntary disclosure agreements help businesses get lower penalties, limit the look-back period, and keep things private. In the end, that protects their finances and their name.

A highly rated SaaS app, available worldwide on the Apple App Store and Google Play Store, used Kintsugi's in-house VDA service. It settled its compliance across many states and saved $236,000 in back taxes and penalties.

How to Successfully Execute a VDA

A successful VDA takes several key steps:

  • Assess Tax Obligations: Study your data in depth to find where you have nexus and what you already owe.
  • Seek Expert Guidance: Work with experts in sales tax, income tax, and use tax to get a plan that fits you.
  • Automate Reporting Processes: Use automation tools to simplify reporting. That cuts human error and makes your checks more accurate.
  • Negotiate Terms: Focus on getting lower penalties, setting the look-back period, and keeping things private the whole way.
  • Ensure Future Compliance: Put long-term compliance systems in place.

The Multistate Tax Commission stresses what a good VDA needs: steady reporting, smart disclosure, and good data management. These help you avoid future audits and criminal prosecution.
