UAE VAT Calculator 2026: Add & Reverse 5% VAT

How Do I Calculate VAT in the UAE?

To calculate VAT in the UAE you work from the standard rate of 5%. To add VAT to a net price, multiply the net amount by 1.05, so a net price of AED 1,000 becomes AED 1,000 x 1.05 = AED 1,050, of which AED 50 is the VAT. To reverse or remove VAT from a gross price that already includes it, divide the gross by 1.05, so a gross total of AED 1,050 / 1.05 = AED 1,000 net, leaving AED 50 as VAT. The VAT amount alone is the net multiplied by 0.05 when you add, or the gross multiplied by the VAT fraction 5/105 when you reverse. The standard UAE VAT rate is set at 5% by the Federal Tax Authority.

Those two formulas, net x 1.05 to add and gross / 1.05 to reverse, are the entire engine of UAE VAT arithmetic, and almost every calculation you will ever do is a variation on them. This guide turns them into a practical calculator you can use without any software: clear formulas, a quick-reference table, and a long run of worked AED examples covering invoices, retail prices, professional fees, imports and multi-item bills. At Noble Core Ventures we set up and advise UAE businesses every day, and getting the 5% maths right, on both the add and the reverse side, is one of the most common things founders ask us about once they cross the registration threshold. Read on for the full method, the thresholds that decide whether you charge VAT at all, and the mistakes that quietly cost businesses money.

The Two Core Formulas: Adding and Reversing 5% VAT

Everything in UAE VAT calculation reduces to two directions of travel. Either you have a price before tax and you need to add VAT on top, or you have a price that already includes tax and you need to pull the VAT back out. Get comfortable with both and you can handle any quote, invoice or receipt in the country.

Adding VAT is the simpler of the two. You start with the net price, the genuine value of the goods or service before any tax. Because VAT is 5%, the gross price is the net plus five percent of the net, which is the same as multiplying the net by 1.05. The factor 1.05 is simply 1 (the original price) plus 0.05 (the 5% tax). If you want the VAT figure on its own, you multiply the net by 0.05. So for any net price, the VAT equals net x 0.05 and the gross equals net x 1.05. These are the only two operations you need on the add side, and they always agree: the VAT you calculate at 0.05 will always be exactly the difference between the net and the gross.

Reversing VAT is where most errors creep in, so it deserves care. When a price already includes 5% VAT, that gross figure represents 105% of the net, because it is the net (100%) plus the VAT (5%). To recover the net you therefore divide the gross by 1.05, not by 1.05 of some other number, and not by subtracting 5% of the gross. Once you have the net, the VAT is simply the gross minus the net. A faster single step for the VAT portion alone is to multiply the gross by the VAT fraction, which for a 5% rate is 5/105 (this simplifies neatly to 1/21). Both routes, dividing by 1.05 then subtracting, or multiplying by 5/105 directly, give exactly the same VAT figure, so use whichever you find easier to remember.

The reason the reverse calculation trips people up is that the 5% is measured against the net, not the gross. A common instinct is to take a VAT-inclusive total and simply subtract 5% of that total to "remove" the tax. That is wrong, because 5% of the larger gross figure is more than the 5% that was originally added to the smaller net figure. We will demonstrate this with hard numbers later in the worked examples, because seeing the small but real discrepancy is the quickest way to never make the mistake again.

UAE VAT Rate and Threshold Quick Reference (2026)

The table below gathers the headline figures you need for any VAT calculation in the UAE. These are indicative figures for 2026 based on the standard VAT regime; the 5% standard rate and the registration thresholds are official, but you should always confirm current rates and thresholds with the authority before relying on them for invoicing or registration decisions.

These nine rows are, in effect, your pocket calculator. The top half handles the arithmetic of any single price, and the bottom half tells you whether you are even required to be charging VAT in the first place. We will now put the arithmetic rows to work across a series of realistic AED scenarios.

Worked Example 1: Adding 5% VAT to a Net Invoice

Imagine you run a consultancy and you are billing a client a net professional fee of AED 4,000. You need to add VAT and show the client a correct, tax-compliant invoice.

Start with the net amount of AED 4,000. The VAT is the net multiplied by 0.05, so AED 4,000 x 0.05 = AED 200. The gross invoice value is the net multiplied by 1.05, so AED 4,000 x 1.05 = AED 4,200. As a check, the net plus the VAT should equal the gross: AED 4,000 + AED 200 = AED 4,200, which it does. On the invoice you would show three lines: the net amount of AED 4,000, the VAT at 5% of AED 200, and the total payable of AED 4,200. Your client pays you AED 4,200, of which AED 200 is the output VAT you are collecting on behalf of the Federal Tax Authority and will report on your next return.

Now scale it up. Suppose the engagement is larger and the net fee is AED 27,500. The VAT is AED 27,500 x 0.05 = AED 1,375, and the gross is AED 27,500 x 1.05 = AED 28,875. Again the arithmetic ties out: AED 27,500 + AED 1,375 = AED 28,875. Whether the number is small or large, the method never changes; the 5% is always taken on the clean net figure, and the factor of 1.05 always delivers the gross in one step.

Worked Example 2: Reversing VAT Out of a Gross Price

Now flip the direction. A supplier sends you a receipt showing a total of AED 1,050 and tells you the price is VAT-inclusive. You want to know how much of that AED 1,050 is the genuine net cost and how much is recoverable input VAT.

Divide the gross by 1.05 to find the net: AED 1,050 / 1.05 = AED 1,000. The VAT is the gross minus the net: AED 1,050 − AED 1,000 = AED 50. As a cross-check, use the VAT fraction directly on the gross: AED 1,050 x 5 / 105 = AED 50, which matches exactly. So of the AED 1,050 you paid, AED 1,000 is the net cost and AED 50 is the input VAT you may be able to recover on your return if you are registered and the purchase is for taxable business use.

Take a larger, less round example to prove the method works for any figure. A VAT-inclusive equipment invoice comes to AED 8,925. The net is AED 8,925 / 1.05 = AED 8,500, and the VAT is AED 8,925 − AED 8,500 = AED 425. Checking with the fraction: AED 8,925 x 5 / 105 = AED 425. The two methods agree, confirming that AED 8,500 is the net and AED 425 is the input VAT contained in that gross figure. This is the calculation you run on virtually every supplier receipt that quotes a tax-inclusive total.

Worked Example 3: The Reverse-VAT Mistake That Costs Money

This example exists purely to burn the most common reverse-VAT error out of your habits, because it is the single mistake we see most often. Take the same VAT-inclusive total of AED 1,050.

The correct method divides by 1.05: AED 1,050 / 1.05 = AED 1,000 net, with AED 50 of VAT. The incorrect method, which many people reach for instinctively, is to subtract 5% of the gross: 5% of AED 1,050 is AED 52.50, giving a "net" of AED 997.50 and overstating the VAT at AED 52.50. The two answers differ by AED 2.50 on a small invoice, which feels trivial, but the error scales linearly. On a VAT-inclusive total of AED 105,000 the correct net is AED 100,000 with AED 5,000 of VAT, while the wrong subtract-5% method gives a "net" of AED 99,750 and overstates the VAT by AED 250. Across a year of invoices that misstatement compounds into a real reporting and reconciliation problem. The lesson is permanent: never subtract a flat 5% from a gross figure to remove VAT; always divide by 1.05 or multiply by 5/105.

Worked Example 4: A Multi-Item Invoice

Real invoices rarely have a single line. Suppose you are billing a client for three net items: design work at AED 1,500, printing at AED 700, and delivery at AED 400, all standard-rated at 5%.

First sum the net line items: AED 1,500 + AED 700 + AED 400 = AED 2,600. Apply 5% to that combined net subtotal: AED 2,600 x 0.05 = AED 130 of VAT. The gross invoice total is AED 2,600 x 1.05 = AED 2,730, which also equals AED 2,600 + AED 130. The general best practice is to total the net first and apply VAT to the subtotal, rather than calculating and rounding VAT on every individual line, because per-line rounding can introduce tiny discrepancies that accumulate. Your final invoice shows a net subtotal of AED 2,600, VAT at 5% of AED 130, and a total payable of AED 2,730.

The picture changes when an invoice mixes VAT categories. Suppose the same invoice also includes a zero-rated export service of AED 1,000. Zero-rated supplies are taxable at 0%, so they carry no 5% charge. You apply 5% only to the standard-rated subtotal of AED 2,600, producing AED 130 of VAT as before, and you add the AED 1,000 zero-rated line with AED 0 VAT. The total payable becomes AED 2,600 + AED 130 + AED 1,000 = AED 3,730. Keeping the standard-rated, zero-rated and exempt portions clearly separated on the invoice is essential; applying 5% across the whole bill, including the zero-rated line, would overcharge the client and misstate your output VAT.

Worked Example 5: Working Out Input VAT vs Output VAT on a Return

The real point of all this arithmetic is the periodic VAT return, where you net your output VAT against your input VAT. Suppose that in a quarter your taxable sales had a net value of AED 200,000, and your VAT-bearing business purchases had a net value of AED 120,000.

Your output VAT is the 5% you charged on sales: AED 200,000 x 0.05 = AED 10,000. Your input VAT is the 5% you paid on purchases: AED 120,000 x 0.05 = AED 6,000. The amount you pay to the Federal Tax Authority is the output VAT minus the input VAT: AED 10,000 − AED 6,000 = AED 4,000. That AED 4,000 is the net VAT you remit for the period.

Now consider a quarter dominated by investment. Your taxable sales net AED 50,000 while you spend heavily, with VAT-bearing purchases of AED 90,000 net. Output VAT is AED 50,000 x 0.05 = AED 2,500, and input VAT is AED 90,000 x 0.05 = AED 4,500. Because input VAT exceeds output VAT, you are in a net refund position of AED 4,500 − AED 2,500 = AED 2,000, which you can typically reclaim from the Federal Tax Authority. This is exactly why some startups register voluntarily once they reach AED 187,500: registering lets them recover the input VAT on their setup and equipment costs rather than absorbing it.

Worked Example 6: VAT on an Import

VAT also applies to imported goods and certain imported services, often through a reverse-charge mechanism, and the underlying 5% arithmetic is identical. Suppose you import goods with a customs value of AED 30,000.

The VAT due is the value multiplied by 0.05: AED 30,000 x 0.05 = AED 1,500. Under the reverse-charge mechanism that commonly applies to imports for VAT-registered businesses, you generally account for this AED 1,500 as both output VAT and input VAT on the same return, so for a fully taxable business the net cash effect can be neutral. The exact treatment depends on your registration status, the nature of the goods or services, and whether any customs duty applies on top, all of which are separate from VAT. The calculation principle, however, never changes: the VAT element is the value multiplied by 0.05, the same factor you use everywhere else. Because import VAT, customs duty and reverse-charge reporting interact in ways specific to your activity, confirm the correct treatment with the Federal Tax Authority or a tax adviser before filing.

When You Actually Have to Charge VAT: The Thresholds

All of the arithmetic above only matters if you are required to charge VAT in the first place, and that depends on your turnover relative to two thresholds set by the Federal Tax Authority. Registration becomes mandatory once the value of your taxable supplies and imports over the previous twelve months exceeds AED 375,000, or you reasonably expect it to exceed AED 375,000 within the next thirty days. That second, forward-looking test matters: a business that wins a large contract can become liable to register before its trailing twelve-month figure has caught up, so the threshold is a rolling test rather than an annual one.

The second figure, AED 187,500, is the voluntary registration threshold. Once your taxable supplies, imports or taxable expenses reach this level you may register even though you are not obliged to, and below AED 187,500 you cannot register at all. Crucially, both thresholds are measured on taxable turnover, not profit. They include standard-rated supplies at 5% and zero-rated supplies at 0%, plus taxable imports. This catches founders off guard, because a high-revenue, low-margin trading business can cross AED 375,000 on turnover while making very little profit, and is therefore firmly inside the mandatory regime despite feeling small in cash terms. If you are weighing up where you sit, our guide to whether small businesses pay VAT in the UAE and our walkthrough of VAT registration in the UAE cover the decision and the process in detail.

It is also worth being clear that VAT is not the same tax as corporate tax. VAT is a 5% consumption tax collected on sales, while UAE corporate tax is a 9% tax on business profits above AED 375,000 of taxable income. They are completely separate regimes with separate registrations, returns and thresholds that happen to share a number, and a business can easily be liable for both, one, or neither depending on its turnover and profit. If the relationship between the two is unclear, our comparison of corporate tax versus VAT in the UAE sets them side by side. The Ministry of Finance is responsible for the broader UAE tax policy framework, while the Federal Tax Authority administers both VAT and corporate tax day to day, including registration through the EmaraTax portal.

Rounding, Tax Invoices and Getting the Details Right

Once your calculations are correct, the way you present them on a tax invoice matters just as much. A valid tax invoice generally needs to show the net amount, the VAT rate and amount, and the gross total, along with your Tax Registration Number and the other particulars required by law. Showing the 5% VAT as a distinct line, rather than burying it in a single combined price, is what allows your customer, if registered, to recover the input VAT and is what the Federal Tax Authority expects to see.

Rounding deserves a brief, careful word. Because 5% of many AED amounts produces fractions of a fil, you will sometimes need to round the VAT figure. The standard approach is to calculate VAT on the net subtotal and round the result using a consistent, conventional rounding method, applying it once to the total rather than repeatedly across every line. For the round numbers most businesses deal with, the VAT lands exactly, but for awkward figures a consistent policy avoids the tiny discrepancies that otherwise show up when an auditor or a client reconciles your invoice. Whatever convention you adopt, apply it consistently, and keep the underlying net, VAT and gross figures visible so the arithmetic can always be checked back to the two core formulas.

Common Mistakes to Avoid

The first and most expensive mistake is reversing VAT by subtracting a flat 5% from a gross, tax-inclusive figure instead of dividing by 1.05. As Worked Example 3 showed, 5% of the gross is larger than the 5% that was originally added to the net, so this method always understates the net and overstates the VAT. On small invoices the gap looks negligible, but it scales directly with value and quietly corrupts your input VAT recovery and reconciliations across a year. The correct reverse is always divide by 1.05, or multiply the gross by 5/105.

A second common error is treating the VAT you collect as your own money. The output VAT in your prices is collected on behalf of the Federal Tax Authority and is never your revenue. Founders who spend it as income find themselves short of cash when the return falls due. The discipline of setting collected VAT aside, or at least never counting it as earnings in your cash-flow planning, is one of the most valuable habits a registered business can build, and it prevents the painful scramble that catches out so many young companies at their first return.

The third mistake is applying 5% to supplies that should not carry it. Zero-rated supplies are taxed at 0% and exempt supplies fall outside VAT entirely, so charging 5% across a whole invoice that contains zero-rated or exempt lines overcharges the customer and misstates your output VAT. Always separate the categories and apply 5% only to the standard-rated portion, as in Worked Example 4. Conversely, forgetting to charge VAT on genuinely standard-rated supplies once you are registered leaves you owing the tax out of your own pocket.

A fourth mistake is ignoring the thresholds, in both directions. Some businesses cross AED 375,000 in rolling twelve-month turnover and keep trading without registering, exposing themselves to penalties and back-dated VAT they may never have collected from customers. Others register voluntarily without thinking through whether they are ready for the ongoing filing obligations. Monitor your rolling turnover continuously rather than once a year, and make the registration decision deliberately. If your turnover is climbing toward AED 187,500 or AED 375,000, plan the registration before you cross the line, not after.

The final mistake is treating any figure, including those in this guide, as the last word. The 5% standard rate and the AED 375,000 and AED 187,500 thresholds are official, but VAT categories, special zone rules, import treatment and the precise particulars of a valid tax invoice can change and can turn on the specifics of your activity. Always confirm current rates, thresholds and treatment with the Federal Tax Authority at tax.gov.ae before relying on a number for invoicing, registration or a return.

How Noble Core Ventures Helps

Getting VAT right is partly arithmetic and partly judgement, about which supplies are standard-rated, zero-rated or exempt, whether you have crossed a threshold, how imports and the reverse charge apply to your activity, and how to structure compliant invoices from day one. The two formulas in this guide, net x 1.05 to add and gross / 1.05 to reverse, will carry you through the everyday calculations, but the surrounding decisions are where founders most often want a steady hand. At Noble Core Ventures we help UAE businesses assess where they sit against the registration thresholds, register through the correct channels, set up VAT-compliant invoicing and accounting, and stay aligned with the Federal Tax Authority's requirements as they grow. If you are approaching a threshold, unsure how VAT and corporate tax interact, or simply want your 5% maths and your invoices to be unquestionably correct, talk to us before your next return is due.
