Reverse Charge Mechanism in UAE VAT: The Plain-English Guide
The reverse charge mechanism (RCM) is the single biggest source of FTA penalty notices we see for UAE SMBs. Not because the rules are complex — they aren't — but because most accounting software doesn't post the second leg of the entry by default, and the company never realises until the audit. This guide explains when RCM applies, how to book it correctly, and exactly where each piece lands on the VAT return.
What reverse charge actually means
Normally, the seller charges VAT, collects it from the buyer, and pays it to the FTA. Under reverse charge, the seller does not charge VAT — instead, the buyer accounts for both the output and the input VAT on the same return. The buyer is effectively self-assessing the tax that a foreign or special-case supplier could not collect.
For most VAT-registered buyers, the net cash impact is zero — the output and input cancel out — but you still have to record both legs. If you only record the expense without the VAT entries, you'll under-declare your output VAT on Box 3 and your input on Box 10, and the FTA will eventually find it during an audit reconciliation.
When does RCM apply in the UAE?
The Federal Decree-Law No. 8 of 2017 (the VAT Law) and its Executive Regulation list specific cases. The most common ones for SMBs:
1. Imports of goods from outside the GCC
When you import goods into the UAE from a country outside the GCC, the customs declaration triggers RCM. The clearance amount appears on your FTA portal pre-populated under Box 6. You also need to record the matching input VAT on Box 10.
2. Services received from outside the UAE
Software subscriptions (AWS, Google Workspace, Microsoft 365, Stripe, Slack), consulting from a foreign firm, advertising on Meta or Google, design services from an overseas freelancer — any service supplied by a non-resident to a VAT-registered UAE recipient triggers RCM. The supplier's invoice has no VAT; you self-account at 5%.
3. Goods supplied from a designated zone to the UAE mainland
Covered in detail in our free zone vs mainland article. The mainland buyer treats it as an import and applies RCM.
4. Specific domestic categories
- Gold and diamonds traded between VAT-registered dealers (Cabinet Decision No. 25 of 2018) — the buyer issues a written declaration that they are registered and acquiring for resale or manufacturing.
- Scrap metal and recyclable materials traded between registered businesses (Cabinet Decision No. 99 of 2022).
- Hydrocarbons — crude oil, natural gas, and refined products supplied to a registered buyer that will resell or use in producing energy.
The bookkeeping entries — service import example
Suppose your UAE-registered company subscribes to AWS for AED 10,000 per month. AWS's Ireland-billed invoice shows no VAT. Here is the correct entry on receipt of the invoice:
| Account | Debit (AED) | Credit (AED) |
|---|---|---|
| Cloud services expense | 10,000 | |
| Input VAT (recoverable) | 500 | |
| Accounts payable — AWS | 10,000 | |
| Output VAT — reverse charge | 500 |
On the next VAT return:
- Box 3 (Supplies subject to reverse charge): AED 10,000 net + AED 500 output VAT
- Box 10 (Recoverable input tax): AED 500 input VAT
Net VAT payable: zero. But the values still need to appear on the return. Skipping them is the most common error.
What if your input VAT isn't fully recoverable?
If your business makes some exempt supplies — typically residential rent, bare land sales, or certain financial services — your input VAT is only partially recoverable. The reverse charge output VAT is still 100% payable, but the matching input is restricted. In that case RCM has a real cash cost, and you must run a partial-exemption calculation each return period. Don't skip it; the FTA audits this hardest in mixed-use businesses.
Invoicing under RCM — what your invoice must say
When you make a supply that the buyer will reverse-charge (for example, you sell scrap metal to another registered dealer), your tax invoice must show "Reverse charge applies — VAT to be accounted for by the recipient" in a clearly visible place, and the VAT amount column must be zero (not 5%). You still issue a sequential tax invoice with all the standard fields, your TRN, the buyer's TRN, and a description of the goods.
The five RCM mistakes that trigger penalties
- Missing the output VAT side. Booking the AWS bill as a simple expense without the corresponding output. Net VAT looks the same, but Box 3 is understated and the FTA's data-matching catches it.
- Wrong period. RCM is due in the period in which the supply takes place, not the period in which the payment leaves your bank. Foreign invoices in foreign currency must be converted at the Central Bank rate on the date of supply.
- Treating zero-rated as RCM. Exports outside the GCC are zero-rated, not reverse charged. They go in Box 4, not Box 3.
- Not getting the buyer's written declaration in gold/scrap deals. If you supply gold or scrap without the written declaration on file, the FTA will deny the reverse charge and treat the supply as standard rated — making you liable for the 5%.
- Forgetting to reverse-charge software subscriptions. Many founders quietly absorb AWS, Stripe, Notion, Figma and similar bills without ever reverse-charging them. Three years of monthly subscriptions × hundreds of vendors adds up fast at audit.
How to make this painless
The right ERP setup makes RCM invisible. Configure a single tax code — call it RCM Services — that posts both the output and input legs automatically. Tag your foreign vendors (AWS, Google, Meta, Stripe, etc.) with that tax code as their default. Then every foreign supplier bill produces the correct four-line entry without anyone thinking about it.
