This page sets out how Hassab (operated by RAMZ for Information Technology LLC) handles VAT on the supplies we make to our customers in Oman and abroad. It is published for transparency and to help our customers reconcile our invoices in their own books.
Registration status
RAMZ for Information Technology LLC is registered for VAT in the Sultanate of Oman. Our Tax Registration Number (TRN) is shown on every tax invoice we issue. The OTA Tax Identification Card is available on request to legitimate counterparties.
Taxable supplies
Subscriptions to the Hassab service supplied to customers established in Oman are standard-rated at 5% VAT. The VAT amount is shown separately on every invoice in OMR.
Cross-border supplies
Subscriptions supplied to a business customer established outside the GCC implementing states are zero-rated as exports of services, where the place of supply rules permit. Supplies to non-resident customers in GCC implementing states follow the place-of-supply rules in force at the time of supply. Where the customer is required to self-account under a reverse charge mechanism in their own jurisdiction, our invoice indicates this.
Prices
Prices quoted on this website and in proposals are exclusive of VAT unless explicitly marked "VAT-inclusive". The applicable VAT (if any) is added at invoicing.
Invoice format
Every invoice we issue meets the OTA tax-invoice requirements: it carries our legal name, address, TRN, the customer's details (and TRN for B2B Oman customers), a sequential invoice number, the issue date and supply date, the description of services, the taxable amount, the VAT rate and amount, and the total payable. Where amounts are not in OMR, the OMR equivalent and exchange rate are shown.
Credit notes and refunds
Where we issue a credit note we follow the OTA Executive Regulations: the credit note references the original invoice, states the reason for issue, and shows the corrected VAT. Refunds are paid in the original currency to the original payment method.
Records and audit
We retain all VAT-relevant records (invoices issued and received, contracts, customs documents, supporting correspondence) for at least 10 years from the end of the relevant tax period, and 15 years for immovable-property records, in line with the Oman Executive Regulations. Customer-side copies remain accessible to the customer in their Hassab tenant for the duration of the subscription.
Disputes and corrections
If you believe an invoice we issued is incorrect (wrong rate, missing TRN, calculation error), email billing@hassab.io within 30 days. We will investigate, issue a credit note where appropriate, and reissue a correct tax invoice.
