Frequently asked questions
Do I need a dedicated solution for global VAT payments?
If your business pays VAT in multiple countries you’ll find yourself dealing with different currencies, payment instructions and deadlines. OneTax simplifies that by letting you pay in one currency through a single platform.
How does OneTax work to streamline tax payments?
OneTax lets you make one bulk payment in your chosen currency, and it handles disbursement to all the relevant tax authorities. You also get real-time tracking of payment status and standardised references so you avoid manual errors.
Can OneTax help with currency exchange and cost control?
Absolutely. OneTax fixes foreign exchange (FX) rates for up to two weeks and supports payment in a single currency. This means fewer surprises from fluctuating exchange rates and lower overall cost of global VAT payments.

OneTax supports VAT payments to many countries worldwide, including Spain, Germany, France, the UK, Australia, the US and more. Additional countries and currencies can be added on request to meet your business needs.
