Sales tax software comparisons — FAQs
Compare the list of your potential tax providers on five dimensions:
- multi-state filing coverage (all 50 states, or just a subset)
- pricing transparency (published rates vs. quote-based, no trial)
- support quality (can you reach a real person by phone when a state sends a notice)
- integration depth (does it connect to Shopify, BigCommerce, WooCommerce, or your platform natively)
- compliance automation (does it handle calculation, nexus tracking, filing, remittance, and registration, or just pieces)
For businesses filing in multiple states, also ask whether the vendor is an SST Certified Service Provider, which determines whether you pay for filing in 24 states or get it free.
It depends on your business. Enterprise companies with tax teams tend toward enterprise level providers like Avalara or Vertex. Self-serve single-channel sellers often start with their platform’s native tool. Growing mid-market businesses that want filing owned by the provider tend toward platforms like TaxCloud.
Easier than most vendors make it sound. For Shopify and BigCommerce sellers, the checkout calculation is already handled by the platform, so switching compliance providers is primarily a credential transfer and data migration.
Most migrations take about a month. The key is timing the cutover between filing periods so no returns are missed or duplicated. TaxCloud provides a dedicated onboarding person and imports historical order data.
A CSP is certified under the Streamlined Sales Tax (SST) program to file and register on behalf of remote sellers in 24 participating states at no cost.
Only TaxCloud and Avalara hold CSP certification among major sales tax platforms. For ecommerce businesses filing in 10 or more states, SST access is the single biggest cost lever in sales tax compliance, saving up to $20,000 per year for a 20-state brand. Most newer and startup-focused tools are not CSPs, so every state filing carries a fee regardless of volume.
The cost of sales tax software depends on your sales volume, the number of states where you sell, and the integrations you use. Pricing models vary across the industry: some providers charge a flat subscription, others use tiered or volume-based pricing, and some charge per filing or per transaction.
At TaxCloud, we believe that sales tax compliance should not be overpriced. Our two plans start at $19/month for Starter and $79/month for Premium, with additional services available as your business needs them. As you scale, volume discounts apply, making the per-unit cost even lower.
