WHY USE FONOA LOOKUP?

Instant, accurate tax ID validation

Ensuring the accuracy of your customers' tax IDs is crucial to managing compliance. Without verification, you may be charging the wrong amount of tax, providing a poor customer experience, and be liable for any missing taxes. With Fonoa Lookup you can:

Recover indirect taxes charged on domestic purchases
Confirm if your platform sellers charged tax correctly.
Confirm your customer’s tax status
To calculate tax on cross-border sales, you must know if your buyer is a business or a consumer - and that they've got a valid/active tax ID.
Know the right tax treatment of your transactions, any time
If you’re a marketplace, you must know if your sellers are registered for taxes before making calculations on their behalf.
Ensure your Data Sharing report contains valid tax IDs
Affected platforms must confirm tax ID numbers before fulfilling their reporting obligations (e.g. DAC7).

CHALLENGES

What can go wrong if I don’t validate tax ID numbers?

Charging the wrong amount of tax.
You’re at risk of reducing your profit margins. And it may cause issues with local tax authorities.
Poor customer experience.
Approving tax incorrectly can result in customer complaints and time spent on unwinding transactions (and correcting invoices)

CHALLENGES

Know when your customers are taxable and when not

Improve your margins

By validating your business customers' Tax IDs, you are ensuring that you are dealing with tax registered business customers (B2B) and know when not to charge indirect taxes on your cross-border transactions. This leads both to cost-savings and gross margin increase vs approaching every transaction as taxable (B2C) and charging unnecessary taxes like VAT and GST that you have to remit to the tax authorities once you charge it.

B2B complexities

Any business that sells to business customers cross-border, will need to collect their Tax IDs to determine if the transaction is taxable and for invoicing purposes.

Not charging for VAT or GST

If tax IDs are not valid for various reasons, or have expired, merchants will not be able to properly invoice these customers and will wrongfully not charge sales tax, VAT or GST.

Merchants are held liable for taxes

Tax authorities across the world hold merchants liable for under-declared and unpaid taxes, along with late interest fees and penalties.

Automated solution for your online business

B2B / B2C

Automatically determine if a transaction is B2B or B2C

Tax rate determination

Understand whether the transaction is subject to sales tax, VAT or GST
