# POST /tax/rates stops working

Calls to POST /tax/rates on Printful API stopped working on September 8, 2025.

On September 8, 2025, Printful will shut down the POST /tax/rates endpoint entirely. Calls made to POST /tax/rates after this date will fail. The sunset process began on July 29, 2025, gradually lowering the rate limit until the endpoint's final removal.

## What to use instead

There is no direct replacement endpoint. To calculate totals with tax, use the order estimation endpoint POST /orders/estimate-costs, or switch to an external tax provider if standalone tax rates are required.

Printful offers no standalone tax rate endpoint anymore: tax rates must come from another provider.

## Printful API's words

> On July 29, 2025 , we started the sunset process. The rate limit is being reduced by 10 RPM each week (starting with 60) until it reaches 0 on September 8, 2025 , at which point the endpoint will be removed entirely.
