6 Questions to Ask Before Selecting a Sales Tax Service Provider

What do Sales Tax Service Providers Do?

A good sales tax service provider handles virtually everything related to sales tax compliance and management. They become an invaluable asset that lifts the sales tax burden off your shoulders.

The most important services sales tax providers should offer include:

• Filing Returns and Remitting Payments. This core function involves preparing, filing, and paying your sales tax returns in every required jurisdiction by each filing due date. Reputable sales tax service providers guarantee accurate, on-time filing. But that’s just the tip of the iceberg when it comes to sales tax.
  
  
• Preparing Transaction Data for Filings. Most businesses will have transaction data in multiple e-commerce, accounting, or ERP systems that will need to be aggregated for sales tax purposes. If done manually, this could take many hours per month.
  
  
• Managing Audits. Sales tax service providers act as your audit defense team from start to finish. Their expertise protects you from penalties, fines, and other costly errors if you were to handle an audit yourself. Last year, providers managed an average of 715 notices per client.
  
  
• Monitoring Law Changes. Sales tax service providers vigilantly track relevant sales and tax law changes across jurisdictions. They then proactively implement required updates to your business. This prevents non-compliance issues before they happen.
  
  
• Cleaning Up Back Taxes. Sales tax service providers can re-file past returns, negotiate tax relief programs, and resolve outstanding liabilities from previous non-compliance. This removes a huge burden.
  
  
• Being Your Trusted Advisor. Having a team that you can turn to for advice is invaluable, especially when they understand your business’s unique history and setup. 

Additional services sales tax providers may offer include:

• Nexus Studies and Sales Tax Exposure Estimates. These are to determine where your business owes sales tax, and what your overall sales tax risk is in that jurisdiction.
  
  
• Notice and Mail Management. This may sound trivial, but if sales tax notices aren’t responded to promptly, it can result in substantial penalties. Last year, we received an average of 715 state notices and emails for each of our clients.
  
  
• Product Taxability Analysis. Providers can advise on whether products or services may qualify for tax exemptions, or if it is worth bringing in an attorney for a definitive “Product Taxability Study.”
  
  

• Sales Tax Setting Setup. Sales tax service providers can set up and test your e-commerce, accounting, and ERP systems to accurately calculate and collect sales tax based on the products you sell.
  
  

• Sales Tax Permits. Sales tax service providers can help you determine what permit is required, and then help open or close them in new jurisdictions.
  
  

• Monitoring Sales Tax Variances. Sales Tax Variance is the difference between how much sales tax you collected versus how much you should have collected. Sales tax service providers should monitor this to ensure your systems continue to work correctly.
  
  
• Exemption Certificate Management. This can include collecting, organizing, storing, and managing customer tax exemption certificates to validate non-taxed transactions.
  
  
• Sales Tax Refund Management. Submitting and tracking refund claims when overpaid tax is identified.
  
  

• Coordinating with Your CPA for Multi-State Income Tax. Most businesses that owe sales tax in multiple states will also owe income tax in multiple states. Your sales tax service provider should be able to coordinate with your CPA to provide a breakdown of what your sales are by state to assist with this process. 

Sales Tax Service Provider vs. Sales Tax Software: What’s Better for Your Business?

Deciding between sales tax software and a full-service provider comes down to understanding your business's specific needs and situation. Both options aim to simplify sales tax compliance but have key differences that make one or the other a better fit depending on your circumstances.

Consider Sales Tax Software If…

Sales tax software is best suited for businesses with straightforward sales tax needs and some expertise in handling tax compliance in-house. Specific situations where tax software could be a good fit include:

• Your business has a very simple setup, such as selling general merchandise online through just one sales channel. Complex multi-channel and mixed product/service businesses are better suited for a provider.
  
  
• You have a smaller sales volume, such as under $1M per year. Once you reach higher volumes, a provider becomes more cost-effective.
  
  
• You have in-house expertise in multi-state tax requirements and are comfortable managing the entire sales tax workflow internally. Without tax expertise, a provider is recommended.

Consider a Sales Tax Service Provider If…

For more complex business models or a high desire to outsource sales tax, a full-service provider is likely the better choice. Specific situations where a provider would be recommended:

• You sell diverse product types across multiple sales channels, like online, retail, wholesale, etc. More complexity warrants a provider.
  
  
• You want to outsource sales tax management rather than handle it internally. Providers offer full tax compliance support.
  
  
• You desire the highest level of compliance assurance and support in case of an audit. Providers offer more audit protection.

The key is aligning your resources, needs, and risk tolerance with the solution that makes the most sense. Evaluate both options to determine the optimal approach for your business.

6 Questions to Ask Before Selecting a Sales Tax Service

Here are 6 key questions businesses should ask when selecting a sales tax service provider:

• How do you determine pricing?
  Seek flat-fee pricing with unlimited support to avoid surprises. Beware of providers who nickel and dime for every service. Ask for cost examples based on your sales volume.
  
  
• Can you provide client references?
  Reputable providers should connect you with current clients for candid feedback. Speaking with references is invaluable for gauging customer satisfaction.
  
  
• How will you handle audits?
  Make sure the provider offers full audit support and representation at no extra cost. Audits are inevitable, so you need a provider who can expertly manage them on your behalf.
  
  
• What is your experience in my specific industry?
  You want a provider with expertise in your vertical to understand your business model and any niche issues. Having relevant experience ensures more tailored and strategic advice.
  
  
• How do you stay current on changing tax laws?
  The provider should proactively monitor legal changes and update your business accordingly. This prevents non-compliance and ensures you don't miss key state tax law changes.
  
  
• What technology and tools do you use?
  Look for automated solutions that integrate with your ecommerce platform for efficiency. Modern tools also allow for better data access and transparency.
