What Is Sales Tax Software?

Sales tax software solutions are created to help small businesses charge, collect, report, and submit sales tax. This type of software automates the calculation of the correct amount of sales tax to charge on goods or services based on customers' and businesses' locations.

How Does Sales Tax Software Work?

Sales tax software is meant to simplify and automate managing sales tax data. It typically works by:

• Integrating with software. The best sales tax software connects to a company’s sales systems, such as Shopify, Stripe, or bookkeeping software, and automatically accesses the required state tax information.
• Determining product taxability. Every product or service is taxed differently. Sales tax software should identify which items are taxable and at what rate. This is especially important for businesses that sell various goods and services or sell on multiple platforms.
• Automatic and location-based calculation. Sales tax software should automatically calculate sales tax rates by state and tax jurisdictions. It should use the customer’s delivery or billing address to determine the exact tax rate for each sale.
• Reporting and state filing. The best software for small businesses compiles and calculates the total sales tax that the company owes for each tax period.
• Updates and compliance. It’s no secret that tax laws and rates change frequently. Sales tax providers automatically update their systems to reflect these changes, allowing businesses to stay compliant without worrying about changing laws from tax authorities themselves.
• In-house tax professionals. While the software is important, having tax professionals who can maintain it and work with you is just as vital. One of the best companies for small businesses that offers hands-off onboarding is Zamp. We configure your client account to save you time and ensure everything is done right from start to finish.

How to Choose a Sales Tax Software for Your Small Business

As a small business owner, there’s a lot at stake when you choose sales tax software for your business. Here are some things to think about as you’re choosing selecting a tax solution:

1. The needs of your business

There are several things to consider about your business needs, including:

• Your volume of sales: Consider how many transactions you’re processing daily. Your sales volume can directly impact the type of sales tax software you’ll need.
• Transaction variety: What are the types of transactions you handle? Do you have a lot of products with different taxability rules? If you offer a range of products, you’ll want sales tax software to handle and process correct taxability.
• Your current tax situation: Is your current tax situation working? Or are you spending a lot of time handling it manually? Understanding your situation can help guide you as you develop a strategy for what you need.
• Multi-state operations: Businesses operating in multiple states should consider getting software capable of handling different tax laws across states and local jurisdictions.
• Scalability: When thinking about sales tax software, you want to think about your current and future needs. Look for a solution that can grow and evolve with your business.
• Long-term support: You should not purchase sales tax automation software without long-term support. Several newer tax companies do not emphasize customer service. It’s always important to read reviews and do research before choosing a solution.

2. Research sales tax software solutions

After you’ve assessed your business needs, you’ll want to start researching what solutions may work well for your business needs. Some key features to look for are:

• Customer support: Look for a sales tax software solution with strong customer support that will answer any questions you have about sales tax.

3. Scalability with your business

As your business grows, you want software that can grow and adapt to it. Be on the lookout for:

• Software that is capable of scaling with your business growth: Any software you choose should be able to handle increased transaction volume as your business grows. You’ll also want to ensure it can scale into new geographic areas, whether more states or internationally. Look for software that offers multiple tiers or plans so you can upgrade as your business changes.
• Flexibility: Tax laws constantly change, so you want to ensure that your sales tax solution will adapt to changes. How has the software responded to changes? Does it have a good record of staying up to date with legislative changes? You should consider these things in addition to asking for reviews and references.
• New features and services: You may need more features as your business scales. Look for a sales tax solution that offers a range of add-ons or integrations.
