Why Kintsugi Doesn't Use Streamlined Sales Tax (SST)
Quick answer: SST is a program where a single Certified Service Provider (CSP) files on your behalf in the ~24 states that participate. Kintsugi isn't a CSP. We file directly with every state and jurisdiction you owe in, including the states SST doesn't cover.
If you're currently on an SST provider and want to switch to Kintsugi, that's absolutely possible. See Transitioning from SST to Kintsugi and How to Deregister from Streamlined Sales Tax (SST) State Registrations for the exact steps and timing.
What is SST?
Streamlined Sales Tax (SST) is a program that lets a single Certified Service Provider (CSP) register, file, and remit sales tax on your behalf across the states that participate in the program. Today, that's 24 states.
If all your sales tax obligations fall inside those 24 states, an SST provider can simplify things: one application, one provider, one process.
Why Kintsugi takes a different approach
Kintsugi isn't a CSP, and we don't route your filings through the SST program. Instead, we register and file directly with each state and country where you have an obligation. Here's what that means for you in practice:
With an SST provider (CSP) | With Kintsugi | |
|---|---|---|
Coverage | Only the 24 SST member states | Every U.S. state, plus VAT/GST jurisdictions internationally |
Filing beyond sales tax | Not included — payroll, franchise, or VAT/GST need separate tools | Sales tax, VAT, and GST all handled in one place |
If you switch providers | Your CSP is the filer of record — leaving them can mean losing direct access to your own filing history | You keep direct visibility and control of your filings at all times |
Non-SST states | Still need to be managed separately | Handled the same way as everywhere else — no second process |
The short version: SST can be a good fit if your entire footprint sits inside its 24 member states and sales tax is your only obligation. Kintsugi is built for businesses that operate more broadly, across all 50 states, internationally, or across multiple tax types, and want one platform and one point of contact for all of it.
Already using an SST provider?
Good news! You can still move to Kintsugi. Because Kintsugi files directly with each state rather than through the SST program, your SST registrations need to be closed first and replaced with standard state accounts. There's a specific window each month to do this cleanly (so nothing gets double-filed or missed).

FAQs
Q: Can I switch to Kintsugi if I'm currently registered through SST?
A: Yes. You'll need to deregister from SST first. see Transitioning from SST to Kintsugi for the exact timing so you don't create a gap or overlap in filings.
Q: Does Kintsugi charge more because it's not an SST provider?
A: No. SST's free filing applies only within its 24 member states. Kintsugi's pricing is the same flat model across every jurisdiction we cover, so you're not paying more to get broader coverage.
Q: What if I only sell in SST states right now?
A: An SST provider may work fine for a business that never expects to expand outside those 24 states. If you're growing, selling internationally, or want payroll/VAT/GST handled alongside sales tax, Kintsugi consolidates all of that in one platform.
Q: Will I lose access to my filing history if I leave my SST provider?
A: That depends on your current provider's policies. Some restrict access to historical filings once you're no longer their customer. With Kintsugi, your filing history stays visible and accessible to you directly, with no third party in between.
