NAQIXOman VAT return: how to prepare it from your ledger
The Oman VAT return summarises one tax period of sales, purchases and adjustments. When every figure traces back to an invoice, credit note or supplier bill you can open, the return is quick to review and easy to defend. Here is how to prepare it from the ledger before anyone signs in to the Oman Tax Authority portal.
Oman VAT in brief
Oman introduced VAT in April 2021 at a standard rate of 5%. It is administered by the Oman Tax Authority (OTA). Businesses above the mandatory registration threshold, set by reference to the value of taxable supplies, must register; businesses below it may be able to register voluntarily. Registered businesses file a return for each tax period the OTA assigns, generally a quarter, and pay any VAT due by the return deadline, through the OTA's online portal.
Thresholds, deadlines, penalties and the lists of zero-rated and exempt supplies are set by the VAT law and its executive regulations, and they change from time to time. Treat the figures in this guide as background, and confirm the current position for your business with your tax adviser or the OTA.
What the return covers
The OTA's return form and user guide are the reference for the layout and for what belongs on each line. In broad terms, the return brings together the following:
| Area | What it holds |
|---|---|
| Standard-rated supplies | Sales of goods and services at 5%, and the VAT charged on them |
| Zero-rated supplies | Sales taxed at 0%, such as exports and other categories listed in the law |
| Exempt supplies | Sales the law exempts, which also affect how much input tax you can recover |
| Reverse charge | Services and other supplies bought from abroad on which you account for the VAT yourself |
| Imports of goods | Goods brought into Oman, and the VAT due on them, depending on how import VAT is accounted for |
| Input tax | Recoverable VAT on purchases, expenses and imports |
| Adjustments | Corrections and other changes allowed by the law |
Your accountant maps your figures to the current form; write the mapping down once and reuse it every period.
Seven steps from the ledger to the return
1. Use the right period, in Oman time
Prepare the return for the dates the OTA assigned to you, and read every document date on the company's own calendar. An invoice raised late on the last evening of the quarter belongs to that quarter, even if the server that stored it runs on another time zone.
2. Count only issued tax documents
Issued invoices, credit notes and debit notes belong on the return. Drafts, quotations, proforma invoices, sales orders and cancelled invoices do not. On the purchase side, count supplier bills for goods and services you actually received, and expenses supported by a valid tax invoice, and leave out purchase orders that were never billed.
3. Decide the treatment when the invoice is raised
Each sale should carry its treatment from the start: standard-rated, zero-rated, exempt or out of scope. Reconstructing it at quarter end from item names or memory is where classification errors begin. Agree default treatments with your adviser, using Oman's own law rather than another GCC country's.
4. Separate recoverable from blocked input tax
Not all VAT you pay can be recovered. Some costs, often entertainment and items for personal use, are blocked, and input tax related to exempt supplies may be restricted. Mark these when the bill or expense is entered, so they never reach the input total in the first place.
5. Review imports and the reverse charge
Services bought from suppliers outside Oman with no VAT charged usually fall under the reverse charge. Goods imported through customs create import VAT, which appears on the return in a way that depends on how it was accounted for. Keep customs declarations with the bills they relate to, and list reverse-charge purchases separately so they are not missed.
6. Convert foreign-currency documents consistently
VAT is reported in Omani rials. A sale invoiced in US dollars or dirhams needs a rate fixed on the invoice, and the same rate should flow to the ledger and the return. Agree the source of rates with your accountant and use it every time.
7. Tie the return to the VAT accounts
Compare output and input VAT on the draft return with the balances on your VAT accounts for the same dates. Differences are usually timing, a document posted to the wrong account, or a manual journal that moved VAT without a document behind it. Explain each one before you file.
Review points before filing
- Credit notes in the right period. A credit note generally adjusts the period in which it is issued, which is not always the period of the original invoice.
- Customer details on business sales. Check that business customers carry the details your tax invoices need, and fix the customer record, not just the printout.
- Advance payments. When VAT becomes due on an advance rather than on the invoice, make sure your books follow the same rule. Ask your adviser how the tax point rules apply to you.
- Documents left out. Ask for the list of documents excluded from the return and why: drafts, cancelled invoices, bills without VAT. Errors often hide there.
How NAQIX helps prepare an Oman return
A new NAQIX company set up for Oman starts with a 5% standard rate, a zero rate and an exempt rate. Products carry a default VAT rate, and each invoice carries a tax treatment: standard, zero-rated, exempt or out of scope. Prices can be entered including VAT at the counter, with the VAT worked back from the price.
- The VAT report lists output VAT per invoice and rate, with debit notes included and credit notes as negative rows, and input VAT per supplier bill, with purchase returns as negative rows and expenses included when the supplier's tax number is recorded. It shows the net VAT payable for any date range, read on the company's calendar dates, and can be narrowed to one branch.
- Output and input VAT post to their own ledger accounts, and every journal opens into the document behind it.
- Sales invoices can be raised in other currencies with the exchange rate saved on the invoice. Supplier bills and expenses are recorded in the company's base currency.
- A month-end close signed off by a second person locks the month, so a filed period cannot change underneath you.
NAQIX does not provide an Oman VAT return form, a filing connection with the OTA or an Oman e-invoicing connector. The VAT report lists documents that carry VAT, so your accountant totals zero-rated and exempt sales from the sales register, maps the figures to the OTA form and files the return in the OTA portal. The Tax & compliance and Accounting & reports pages list the features, the NAQIX page for Oman describes the local setup and the overview for Oman, Qatar, Kuwait and Bahrain covers the wider product.
A quarterly rhythm that works
Reconcile banks and review the VAT accounts every month, then close the month. At quarter end, run the VAT report, compare it with the VAT accounts, list the exclusions and hand the pack to the reviewer. Keep the working papers for as long as the law requires, and confirm deadlines and penalties with your tax adviser.
