# Adds new method to retrieve a Tax Calculation

## What’s new

Adds a method to retrieve [Tax Calculations](https://docs.stripe.com/api/tax/calculations.md?api-version=2024-09-30.acacia). You can retrieve Tax Calculations by using the Tax Calculation’s [ID](https://docs.stripe.com/api/tax/calculations/object.md?api-version=2024-09-30.acacia#tax_calculation_object-id). Tax calculations expire after 90 days and you can’t access them after that. Learn more about [calculating taxes](https://docs.stripe.com/tax/custom.md#calculate-tax).

## Impact

Provides access to and management of tax-related data, ensuring that you can reference and verify previously created calculations.
