Kintsugi Capabilities at a Glance

Understanding Kintsugi’s Current Scope

Kintsugi automates sales tax and VAT compliance. It does not cover every tax, every platform, or every scheme, and knowing where the edges are saves you from finding out at a deadline. This article is the single place where those edges are written down.

• Kintsugi covers sales tax, use tax, and VAT. Other tax types are outside its scope

• Kintsugi calculates and files tax. It does not give tax advice for your specific situation

• Read-only integrations report tax. Only tax-engine integrations calculate tax at checkout

• Some jurisdictions, integrations, and features require a specific plan or manual enablement by our team

• Kintsugi does not write data back to your platform except through a tax-engine integration

Tax Types Kintsugi Does Not Handle

Kintsugi is responsible for your sales tax compliance and nothing beyond it.

Registering for sales tax in a state can enroll you in other taxes administered by the same agency, which is why you may receive a notice for a tax Kintsugi did not register you for. Those filings remain yours. See Why You May Receive Notices for Taxes Kintsugi Didn't Register You For.

Calculation Limits

• Kintsugi does not calculate input VAT or input tax credit. You can enter it in Kintsugi if you want it reflected in your figures

• Kintsugi does not calculate late-registration, late-filing, or late-payment penalties and interest

• Kintsugi calculates on standard VAT accounting. Special schemes, including Flat Rate, Cash Accounting, Annual Accounting, and the retail schemes, change how VAT is calculated and are not supported

• Northern Ireland goods rules are not yet in scope

Integration Limits

• Read-only integrations import your data for exposure monitoring and filing preparation. They do not calculate tax at checkout and they do not set tax on invoices in your platform

• Tax-engine integrations are not available on every platform.

• Address changes you make in Kintsugi affect data inside Kintsugi only. They do not sync back to your source system, so fix the address in both places

• Transactions you upload by CSV stay in Kintsugi. They do not sync back to your source platform

• Exemptions are not available from every platform. Rillet, for example, has no exemption data to send, so you import or create exemptions in Kintsugi

• QuickBooks Online is supported. QuickBooks Desktop and QuickBooks Enterprise Desktop are not

Payment and Remittance Limits

• Kintsugi remits tax by ACH only. Credit cards are not accepted for tax remittance, both for security reasons and because ACH supports larger transaction amounts

• Kintsugi pays the tax you owe from the bank account on file. It does not extend credit or front funds on your behalf

Coverage that Depends on your Plan

Some capabilities are gated rather than absent. If something is unavailable to you, the app tells you and offers a path.

If a jurisdiction is not yet enabled for your account, you keep full visibility into your exposure there while the rest is arranged.

What Kintsugi Handles vs. What You Handle

Kintsugi handles:

• Monitoring nexus and exposure across jurisdictions

• Calculating tax on synced transactions

• Preparing, filing, and remitting returns in registered jurisdictions

• Suggesting product categories and corrected addresses for your review

You handle:

• Reviewing and approving product categorizations and address corrections

• Keeping your own invoices and records for the periods each jurisdiction requires

• Filing tax types outside Kintsugi's scope

• Deciding, with a tax advisor where the answer is genuinely unclear, how your business should be treated

What This Article Does Not Cover

This article states scope limits at the platform level. It does not list every platform-specific quirk, since those live in each platform's own article, and it does not list jurisdiction-level taxability rules, which live in the per-country and per-state references. For a limitation specific to one integration, start with that platform's guide.

FAQs

Q: What are Kintsugi's drawbacks?

A: The honest answer is scope. Kintsugi is deliberately a sales tax and VAT platform, so it does not touch income tax, franchise tax, or payroll tax. It also does not give tax advice, it remits by ACH only, and a read-only integration reports tax rather than collecting it. Everything above is listed on this page rather than discovered later.

Q: What does Kintsugi not support?

A: See the tables above. The most common answers are non-sales tax types, VAT special schemes, input tax credit, penalty and interest calculation, credit card remittance, and QuickBooks Desktop.

Q: Is Kintsugi tax advice?

A: No. Kintsugi is software that automates compliance, supported by tax professionals. Articles here are general information about how the product works, not advice about your specific situation.

Q: Can I use Kintsugi if my platform is not supported?

A: Yes. Upload your transactions as a file from Data Sources using the provided CSV template.

Q: Does Kintsugi guarantee I will never receive a notice?

A: No. States send notices for many reasons, including tax types outside Kintsugi's scope. Kintsugi Mail triages the mail and responds to notices that fall within sales tax compliance.

Q: Why does my read-only integration not charge tax to my customers?

A: Because that is what read-only means. To calculate and collect tax at checkout, you need a tax-engine integration, or you enable tax collection in the platform itself.
