Integration
Renttix + TaxJar Integration
Use TaxJar to rate US sales tax on hire invoices, with sandbox testing and a clean separation between what is previewed and what is committed for filing.
US sales tax on hire, calculated and committed by TaxJar.

How it connects
You provide your TaxJar API key, which Renttix uses as a bearer credential. Sandbox and production hosts are both supported, and a health check confirms connectivity so a mistyped key surfaces during setup rather than on a customer's invoice.
As with Avalara, Renttix keeps preview and commitment separate. Quotes and drafts are rated for display without being recorded as filed transactions; issued invoices are committed. The distinction matters because a rental pipeline contains a lot of draft paperwork that never becomes an invoice, and none of it should reach a tax return.

Why it matters
For a hire business operating in the United States — Renttix's largest audience — sales tax is the compliance problem that scales fastest with growth. Every new state, and often every new county or city, brings its own rate and its own view of how rental is treated. Nexus rules mean crossing a threshold in a state can create an obligation you did not previously have.
Key workflows
US sales tax on hire invoices
Hire invoices are rated by TaxJar against the applicable jurisdiction, so deliveries across state and city lines carry the right rate instead of the depot's default.
Drafts stay out of filings
Quotes and drafts are rated for display only; just issued invoices are committed as transactions. The large volume of rental paperwork that never becomes an invoice never reaches a return.
Sandbox and health check
Sandbox and production hosts are both supported, with a health check that confirms the API key works before live invoicing depends on it.
TaxJar is one of two tax engines in Renttix, alongside Avalara, layered over the platform's own tax zone, tax class and tax rule engine. Whichever you use, calculated tax flows on to invoices, payments and the accounting exports unchanged.

How does this differ from the Avalara integration?
They solve the same problem with different providers, and you would normally use one or the other. Both support sandbox and production, and both keep draft previews separate from committed transactions. The choice usually comes down to which service you already hold an account with.
Are quotes reported as taxable transactions?
No. Quotes and drafts are rated so the figure can be shown, but they are not committed for filing. Only issued invoices are committed.
Can I verify the connection before invoicing with it?
Yes. Renttix offers a health check against TaxJar, and the sandbox host lets you exercise the full flow before pointing it at production.
