1. Introduction

Ohio’s sales and use tax rules can be especially complex for the software industry, SaaS
providers, and technology firms. The state doesn’t take a one-size-fits-all approach when it
comes to digital goods and tech services. Instead, taxability depends heavily on factors like how software is delivered (physically or electronically), whether it’s prewritten or custom-built, and how related services are structured—especially if they fall under categories like automatic data processing (ADP), computer services, or electronic information services (EIS).

Purpose of This Guide

This guide is meant to help software and technology companies understand Ohio’s sales and use tax laws as they relate to:

• Nexus Considerations – How physical presence or economic activity in Ohio can create
  a tax obligation.
• Taxability of Software & Services – What’s taxable vs. exempt when it comes to
  prewritten software, custom development, cloud platforms, and data services.
• Sourcing Rules – Where Ohio considers a sale to take place for tax purposes, especially
  for multi-location businesses.
• Audit Considerations – Common red flags and documentation tips to reduce audit risk.
• Voluntary Disclosure Agreements (VDAs) – How to fix prior noncompliance and limit
  penalties before an audit starts.

Why This Matters for Technology Companies

Ohio’s tax rules can affect a wide range of business models, from SaaS subscriptions to software downloads and IT support contracts. Misunderstanding how the state treats these products and services can lead to unintended tax liabilities, penalties, or audit exposure.

For example:

• Prewritten software—whether downloaded or installed from a disk—is taxable.
• Hosted cloud applications used for business purposes may also be taxed under ADP rules.
• Exemptions exist for custom software, internal data sharing within corporate affiliates,
  and temporary storage, but those exemptions must be applied correctly and well-
  documented.

This guide draws on Ohio statutes, administrative rules, and formal guidance from the
Department of Taxation, along with interpretations from resources like the Sales Tax Institute
and Avalara. It’s built to serve as a practical reference point for staying compliant while doing
business in Ohio’s digital economy.
