What is Tax Management (Sales Tax / VAT / GST)?
Calculating, collecting, reporting, and remitting indirect taxes such as sales tax, VAT, and GST on transactions.
Definition
Tax management covers the determination and compliance of indirect taxes applied to sales and purchases, including US sales and use tax, European VAT, and GST in various countries. The correct rate depends on factors such as the product or service, the locations of buyer and seller, and any exemptions, and rates and rules change frequently. Businesses must charge the right tax, keep supporting records, file returns, and remit the tax to the relevant authorities on time. Errors lead to penalties and audit exposure, so accuracy and automation are essential, especially across multiple jurisdictions.
How Tax Management Works in ERP
An ERP determines the applicable tax on each transaction using built-in tax engines or integrations with specialist tax services that maintain current rates and rules by jurisdiction. It records input and output tax separately, handles reverse charge and exemptions, and produces tax reports and returns such as VAT filings. For complex or multi-country operations, the ERP connects to tax automation providers to keep rates current and support electronic filing and e-invoicing mandates.

Frequently Asked Questions
What is the difference between sales tax and VAT?
Sales tax, used in the US, is charged only at the final point of sale to the end consumer, and businesses buying for resale are exempt. VAT, used across Europe and many other countries, is charged at each stage of the supply chain, with businesses reclaiming the VAT they pay on inputs and remitting the net. The end result is similar, but VAT involves tracking both input and output tax. ERPs handle each model and the reporting each requires.
Why do companies integrate a dedicated tax engine with their ERP?
Tax rates, rules, and jurisdiction boundaries change constantly, and in the US alone there are thousands of taxing jurisdictions. Maintaining all of this inside the ERP is impractical, so many companies connect a specialist tax service that keeps rates current and determines tax in real time at transaction entry. The ERP calls the engine, applies the result, and stores it for reporting. This reduces compliance risk and the manual burden of rate maintenance.
