Which accounting software handles sales tax and VAT the best?

Most accounting software includes basic tax rate management - you set up your rates and they apply to invoices. Note.now supports multiple VAT and sales tax rates and applies them automatically based on customer location. For businesses with complex multi-jurisdiction needs, dedicated tools like Avalara or TaxJar offer automatic rate updates and filing.

The key difference between basic built-in tax handling and dedicated tools is rate maintenance. With a built-in system, you are responsible for keeping rates up to date when jurisdictions change their rules. Avalara and TaxJar maintain rate tables continuously, so the correct rate is always applied without manual updates. For businesses selling across multiple US states - where rate changes happen frequently - this automation is worth the additional cost.

Avalara AvaTax is the enterprise choice for sales tax automation - it connects to most accounting and e-commerce platforms and handles rate lookup, calculation, and filing for every US state and many international jurisdictions. TaxJar is a simpler, more affordable alternative popular with e-commerce businesses.

Both Avalara and TaxJar also handle economic nexus rules - the threshold-based rules that determine when a business has sales tax obligations in a state where it has no physical presence. Since the South Dakota v. Wayfair Supreme Court ruling in 2018, most US states impose sales tax obligations on businesses that exceed a transaction or revenue threshold, even without a physical location. Tracking these thresholds manually across 45+ taxing states is effectively impossible without dedicated software.
