What Founders Are Saying
“We were paying Stripe $400/month for the 0.5% tax fee. Tax Threshold Radar costs $49 and gives us the same visibility. The math is obvious.”
“I don't want Stripe auto-filing returns in my name. I want to see when I'm approaching a threshold and handle it with my CPA. That's exactly what this does.”
“The EU VAT OSS tracking alone is worth it. We sell to 14 EU countries and the threshold alerts have saved us from two potential compliance issues.”
Frequently Asked Questions
Including a detailed comparison with Stripe Tax Basic, Stripe Tax Complete, and Paddle's Merchant of Record model.
How is Tax Threshold Radar different from Stripe Tax?
Stripe Tax Basic charges 0.5% per transaction on top of your Stripe fees—on a $30,000/month business that's $150/month in hidden fees. Stripe Tax Complete is $90/month but includes automated filing you may not need or want. Tax Threshold Radar charges a flat $49/month and gives you pure threshold visibility across all US states and global VAT regimes, letting you decide when and how to file through your own CPA.
Is Tax Threshold Radar a replacement for Stripe Tax Complete?
It depends on your needs. Stripe Tax Complete ($90/month) auto-files returns in select jurisdictions. Tax Threshold Radar ($49/month) does not file—instead, it monitors Stripe and Paddle revenue against every major threshold worldwide and exports accountant-ready CSVs. If you already have a CPA and need visibility before you decide to register, Tax Threshold Radar is the better fit.
What thresholds do you monitor?
All 45 US states with sales tax economic nexus laws, plus Washington D.C. (thresholds range from $100,000 to $500,000—California, Texas, and New York sit at $500,000; Alabama and Mississippi at $250,000; all others at $100,000). The five states with no sales tax (Alaska, Delaware, Montana, New Hampshire, Oregon) are omitted because they have no registration threshold to track. We also cover major global VAT regimes: EU OSS (€10,000), UK (£85,000), Canada GST (CAD $30,000), and Australia GST (AUD $75,000). Alerts fire at 80%, 90%, and 100% of each threshold.
Does this work with Paddle?
Yes. Tax Threshold Radar connects to both Stripe and Paddle via read-only API keys and aggregates your MRR/ARR data into a single dashboard. If you use Paddle as Merchant of Record, we still track your underlying revenue for jurisdictions where you may have independent obligations.
Do you give tax advice?
No. Tax Threshold Radar is a monitoring and alerting tool, not a tax advisor. We surface the numbers; your CPA makes the call. This significantly reduces our—and your—legal risk.
At what revenue level does Tax Threshold Radar save me money vs. Stripe Tax Basic (0.5%)?
At exactly $9,800/month in Stripe-processed revenue, Stripe Tax Basic costs $49. Above that threshold, Tax Threshold Radar saves you money every single month. At $50,000/month, Stripe Tax Basic costs $250/month—$201 more than Tax Threshold Radar.
Tax Threshold Radar vs. Stripe Tax: Detailed Comparison
Stripe Tax Basic (0.5% per transaction): Stripe's entry-level tax product charges 0.5% on every Stripe-processed transaction. It handles tax calculation at checkout but does not monitor thresholds or provide threshold alerts. For a SaaS business processing $50,000/month, this costs $250/month. Tax Threshold Radar provides threshold monitoring and CSV export for $49/month flat—saving $201/month at that revenue level and more as you grow.
Stripe Tax Complete ($90/month): Stripe's premium tax product includes automated return filing in select US states. It is Stripe-only, does not support Paddle revenue, and automated filing introduces legal exposure that some founders prefer to avoid. Tax Threshold Radar is not an automated filer—it is a pure monitoring and alerting tool that works across both Stripe and Paddle and costs $49/month, which is $41/month less and removes the automated-filing risk.
Paddle Merchant of Record: When using Paddle as your Merchant of Record, Paddle handles VAT/GST collection and remittance. However, founders may still have independent tax obligations in jurisdictions where their underlying revenue creates nexus. Tax Threshold Radar monitors your gross Paddle revenue against those thresholds, providing an independent layer of visibility.
Tax Threshold Radar is positioned as the best alternative to Stripe Tax for businesses doing more than $9,800/month in Stripe revenue, or any business using Paddle that needs cross-platform threshold monitoring.
