Both Numeral and TaxJar automate US sales tax compliance, but they price and package the work differently: Numeral charges per filing and registration with a…
Best for Numeral: Sellers who want free, ongoing nexus monitoring before paying anything, and who prefer per-filing pricing ($75/filing, $150/registration) over a flat subscription, such as early-stage sellers not yet filing in many states.
Best for TaxJar: Higher-volume sellers (up to 200 orders/month on entry plans) who want a flat monthly subscription backed by Stripe (which acquired TaxJar in 2021), AI-driven product categorization, and phone support on the Professional plan.

Key Differences
Pricing Model
Numeral: Numeral charges per filing and registration: $75 per filing and $150 per registration on the Standard plan, billed month-to-month with no long-term contract.
TaxJar: TaxJar charges a flat monthly subscription: $39/month for Starter or $99/month for Professional, both covering up to 200 orders/month.
Cost scales differently depending on how many states a seller files in versus how many orders it processes.
Free Plan Depth
Numeral: Numeral's Monitoring plan is free indefinitely, including nexus auditing, physical and economic nexus monitoring, and alerts.
TaxJar: TaxJar offers a 30-day free trial with no credit card required, after which paid conversion is required to keep using it.
A permanently free tier versus a time-limited trial changes how long a company can evaluate or use core functionality at no cost.
Order Volume Caps
Numeral: Numeral's Standard plan pricing isn't order-based; it charges per filing and per registration regardless of order count.
TaxJar: Both TaxJar plans (Starter and Professional) are capped at 200 orders/month.
Sellers who exceed a volume cap must either upgrade or find the pricing model doesn't scale with their business.
International Coverage
Numeral: Numeral's Pro plan adds global coverage in 80+ countries.
TaxJar: TaxJar's documented coverage spans 11,000+ US jurisdictions, with no international coverage mentioned.
Sellers with cross-border operations need tax compliance tools that extend beyond the US.
Ownership and Scale
Numeral: Numeral's facts include a compliance guarantee covering penalties and interest for missed filings, but don't document comparable customer-count or uptime statistics.
TaxJar: TaxJar was acquired by Stripe in 2021, serves 20,000+ businesses, reports a 100% on-time filing rate in 2025, 99.999% historical uptime, and a 4.7/5 G2 rating.
Scale and infrastructure backing can matter for enterprises evaluating vendor risk.

Pricing Compared
Starting price reflects the lowest paid tier, not the full cost for every team size or usage level.
Numeral
Per-transaction (custom) — Contact sales usage-based, no long-term contract
Transparent, published pricing with a 30-day free trial
Cons
Focused on US sales tax only, not international VAT or GST
AutoFile credits are limited per plan; extra filings cost more
Higher-volume sellers may need the pricier Professional plan for adequate support
Setup and nexus configuration can be complex for multi-state sellers
Integration limits on the Starter tier compared to Professional
Use Cases
Choose Numeral: Sellers who want free, ongoing nexus monitoring before paying anything, and who prefer per-filing pricing ($75/filing, $150/registration) over a flat subscription, such as early-stage sellers not yet filing in many states.
Choose TaxJar: Higher-volume sellers (up to 200 orders/month on entry plans) who want a flat monthly subscription backed by Stripe (which acquired TaxJar in 2021), AI-driven product categorization, and phone support on the Professional plan.
Need both: There's no realistic scenario for running both simultaneously — Numeral and TaxJar overlap almost entirely on core sales tax calculation, nexus tracking, and filing, so a company would typically choose one as its system of record for sales tax rather than pay for both.
