What is VAT?

Value Added Tax (VAT) is an indirect tax levied on the supply and import of goods and services, with some exemptions. This consumption-based tax is applied at each stage of the supply chain, from production to final sale.

In Saudi Arabia, VAT was introduced in 2018 at 5%, but in response to the COVID-19 pandemic, the rate increased to 15% from July 1, 2020. Businesses and individuals are required to comply with VAT regulations as per government policies.

How to Calculate VAT in KSA?

VAT in Saudi Arabia can be calculated in two ways: adding VAT to a sale price or extracting VAT from an inclusive price.

  • Adding VAT to a Sale Price (Exclusive VAT Calculation)

    This method is used when the VAT is not included in the sale price.

    A. VAT Amount = Sale price × (VAT Rate ÷ 100)

    B. Gross Amount = Sale price × ( 1 + VAT Rate ÷ 100 )

  • Excluding VAT from sale price (Inclusive VAT Calculation)

    This method is used when the sale price already includes VAT.

    A. VAT Amount = Sale Price × ( VAT rate ÷ (100 + VAT rate) )

    B. Net Sale amount = Sale Price × (100 ÷ (100 + VAT rate))

VAT Calculation Example in KSA

Let’s take an example to understand VAT calculation:

Sale amount = SAR 1,000. VAT rate = 15%.

  • If the sale price is exclusive of VAT:

    VAT amount = SAR 1,000 × (15 ÷ 100) = SAR 150

    Gross Amount = SAR 1,000 × (1 + 15) ÷ 100 = SAR 1,150

  • If the sale price is inclusive of VAT:

    A. VAT Amount = SAR 1,000 × (15 ÷ (100 + 15)) = SAR 130.43

    B. Net Sale amount = SAR 1,000 × (100 ÷ (100 + 15)) = SAR 869.56

Benefits of using the KSA VAT calculator

Using our Saudi VAT calculator offers several advantages:

  • Instant VAT Calculation – Quickly compute VAT for any transaction.
  • Accurate Invoicing – Ensure your invoices are correct and compliant.
  • Eliminates Human Errors – Reduces miscalculations and incorrect tax applications.
  • Time-Saving – Automates VAT computation, streamlining business operations.

Frequently Asked Questions

The standard VAT rate in Saudi Arabia is 15%. VAT was introduced on 1 January 2018 at 5% and tripled to 15% on 1 July 2020. Some supplies — such as exports and qualifying international transport — are zero-rated, and a small number are exempt.

Multiply the inclusive price by the rate divided by 100 plus the rate: VAT Amount = Sale Price × (VAT rate ÷ (100 + VAT rate)). At 15%, that is the price × 15 ÷ 115. Subtract the result from the price to get the net amount.

Two ways, depending on what the price already contains. If the price excludes VAT, VAT Amount = Sale price × (VAT Rate ÷ 100) and the gross is the price plus that. If the price already includes VAT, VAT Amount = Sale Price × (VAT rate ÷ (100 + VAT rate)).

MRP is a VAT-inclusive price, so use the inclusive formula. At 15%, VAT = MRP × 15 ÷ 115 and the net value = MRP × 100 ÷ 115. Set the toggle above to “Yes” and the calculator does both for you.

Registration is mandatory for residents whose annual taxable supplies exceed SAR 375,000, and voluntary once they exceed SAR 187,500. Non-resident businesses making taxable supplies in the Kingdom must register regardless of turnover.

Multiply the net amount by 0.15 for the VAT, or by 1.15 to get the gross straight away. SAR 1,000 × 1.15 = SAR 1,150, of which SAR 150 is VAT.

The UAE VAT Calculator works out the 5% VAT on a transaction in either direction — adding it to a net price, or extracting it from a price that already includes it.

What is a VAT Calculator in UAE?

A VAT calculator UAE is an online tool that computes the 5% VAT on a transaction. It works out both VAT-inclusive and VAT-exclusive prices for goods or services.

VAT Calculation Formula

  • For a price exclusive of VAT

    A. VAT Amount = Sale price × VAT rate

    B. Gross Amount = Sale price × (1 + VAT rate)

  • For a price inclusive of VAT

    A. VAT Amount = Sale price × [ VAT rate ÷ (1 + VAT rate) ]

    B. Net Sale Amount = Sale price ÷ (1 + VAT rate)

VAT Calculation Example

Take an item priced at AED 100, with VAT at 5%.

  • Exclusive of VAT: VAT = AED 5, and the gross amount = AED 105.
  • Inclusive of VAT: VAT = AED 4.76, and the net amount = AED 95.24.

VAT Registration Threshold in UAE

  • Mandatory registration – taxable supplies above AED 375,000. Register within 30 days.

The Malaysia SST Calculator works out Sales Tax or Service Tax in either direction — adding it to an exclusive amount, or extracting it from an amount that already includes it.

What is SST?

SST stands for Sales and Service Tax. It is the major consumption tax levied on goods and services traded in Malaysia. It comprises Service Tax, charged on taxable services, and Sales Tax, a single-stage tax levied on goods that are imported into or manufactured in Malaysia.

SST Calculation Formula

Establish the taxable value first, then apply the rate that fits the goods or service.

  • Exclusive of SST

    Use this when the amount does not yet include the tax.

    A. SST Amount = Taxable Value × (Tax Rate ÷ 100)

    B. Total Amount = Taxable Value + SST Amount

  • Inclusive of SST

    Use this when the amount already includes the tax.

    A. SST Amount = Total Amount × ( Tax Rate ÷ (100 + Tax Rate) )

    B. Net Sales Value = Total Amount − SST Amount

SST Calculation Example

Consulting services valued at RM 20,000 attract Service Tax at 6%.

SST Amount = RM 20,000 × (6 ÷ 100) = RM 1,200. Total Amount = RM 20,000 + RM 1,200 = RM 21,200.

Benefits of using the Malaysia SST calculator

  • Works in both directions – add SST to a net amount or extract it from a gross one.
  • Covers every rate – 5% and 10% Sales Tax, 6% and 8% Service Tax.
  • Removes manual error – no rounding slips on invoice values.
  • Speeds up invoicing – the tax and total update as you type.

Frequently Asked Questions

SST in Malaysia is calculated on the taxable services provided or on the sale of goods. Service tax is due when payment is received; sales tax is levied at the point of importation or sale.

Select the type of tax, choose the tax rate, specify whether the amount is inclusive or exclusive, enter the amount, and review the results.

There are four SST rates in Malaysia: service tax at 8% or 6%, and sales tax at 5% or 10%, depending on the nature of the services and goods.

For Sales Tax, registration applies to manufacturers whose taxable goods exceed RM 500,000 over 12 months. For Service Tax, the threshold is also RM 500,000 over 12 months — except for restaurants and food and beverage operators, where it is RM 1,500,000.

An SST calculator is generally better for both accuracy and speed, particularly for inclusive amounts where the reverse formula is easy to get wrong.

Check whether it falls within the gazetted taxable goods or taxable services categories, and whether any exemption order applies to it.

Frequently Asked Questions

ROI in compliance stands for Return on Investment. It measures the financial benefits you gain by investing in a compliance solution. This includes not only the money you save but also the value you gain from increased productivity and risk mitigation.

ROI is crucial in tax and GST compliance because it shifts the focus from compliance as a cost center to a value driver. By quantifying the financial return, you can justify investments in new technology, reduce business risk, and show clear savings from preventing penalties, litigation, and lost credits.

Three. Productivity ROI covers the time and effort taken out of manual compliance work. Money ROI covers Input Tax Credit management. Assurance ROI covers avoiding notices and penalties.

Effective GST compliance directly impacts your ROI by ensuring you meet regulatory requirements and maximize financial benefits. This includes properly claiming ITC, avoiding interest on late payments, and reducing the risk of penalties and legal costs.

The mandatory fields are number of GSTINs, number of PANs, annual sales revenue, B2B sales invoices per year, purchase invoices per year, and industry. Active vendors, payment blocking, and your lost and delayed ITC percentages are optional inputs that make the estimate more precise.

While the calculator provides a strong estimate based on industry averages and your specific data, the final results for your business may vary. The tool uses a set of proprietary assumptions and inbuilt mappers to give you a realistic and data-driven projection.

Input Tax Credit (ITC) is a key component of the Money ROI calculation. The calculator helps you quantify the financial benefits of optimising your ITC process, including recovering lost credits and preventing delayed credits.

Section-level search. The 21 HS sections and their chapter ranges are the stable WCO classification; the exact 6- or 8-digit code and its GST rate live in ClearTax's full HSN database.

How to use

  • Type what you sell — a material, a product or a chapter number
  • The matching HS sections and their chapter ranges filter as you type
  • Note the chapter your goods fall under — the first two digits of the HSN code
  • Open the full ClearTax lookup for the exact 6- or 8-digit code and GST rate

What is an HSN code?

HSN code stands for “Harmonized System of Nomenclature”. This system has been introduced for the systematic classification of goods all over the world. It was developed by the World Customs Organisation and is used consistently across the countries that are party to it.

How the HSN structure works

The Harmonized System is a 6-digit international code. India extends it to 8 digits for greater precision. The digits read outwards from the broadest grouping to the most specific one.

  • First 2 digits – the chapter the goods fall under.
  • Next 2 digits – the heading within that chapter.
  • Next 2 digits – the subheading, which completes the 6-digit international code.
  • Final 2 digits – the Indian tariff item, added on top of the WCO code.

How many digits must you declare?

The requirement is tiered by aggregate turnover. Taxpayers with annual turnover above ₹5 crore must declare 6-digit HSN codes on all invoices. Below that threshold, 4-digit codes are required on B2B invoices only.

SAC codes for services

Services use the Services Accounting Code instead. SAC follows a similar pattern but a different classification system — HSN classifies goods, SAC classifies services.

Frequently Asked Questions

HSN codes are used for the classification of goods, whereas SAC codes are used for services.

Yes, with tiered requirements based on aggregate turnover. Above ₹5 crore, 6 digits on all invoices; below it, 4 digits on B2B invoices.

HSN was developed by the World Customs Organisation and is used to classify goods. The codes are the same to 6 digits across the countries that are under the WCO; digits beyond that are national extensions.

The wrong code can mean the wrong GST rate on the invoice, which leads to short payment or excess payment of tax, mismatches in the recipient's ITC, and notices at reconciliation.

GST calculation formulas

  • Price exclusive of GST

    Use this when the amount does not yet include the tax.

    A. GST Amount = (Value of supply × GST rate) ÷ 100

    B. Price to be charged = Value of supply + GST Amount

  • Price inclusive of GST

    Use this when the amount already includes the tax.

    A. GST Amount = Value of supply – [Value of supply × {100 ÷ (100 + GST rate)}]

    B. Taxable value = Value of supply × {100 ÷ (100 + GST rate)}

GST calculation example

A product valued at ₹1,00,000 charged at 18% GST:

  • Value of product = ₹1,00,000
  • Add: GST @18% = ₹18,000
  • Price to charge on the invoice = ₹1,18,000

CGST, SGST and IGST

CGST, or Central Goods and Services Tax, is GST charged on the sale of goods or services within the same state or Union Territory, the revenue of which is passed to the Central Government.

SGST, or State Goods and Services Tax, is GST charged on the sale of goods or services within the same state or Union Territory, and goes to that state. On an intra-state sale the rate splits equally between the two; on an inter-state sale the whole rate is charged as IGST instead.

Frequently Asked Questions

GST inclusive price means the price or amount already contains the GST value. GST exclusive price means the price or amount before adding the GST value to it.

Yes, the rate list carries the GST rates in force, as notified by the CBIC.

Yes. Toggle the “Selling within the same state?” field to No. That implies an inter-state sale, and the whole rate is charged as IGST.

Yes. Businesses can use a GST calculator to arrive at the amounts to be mentioned on an invoice.

Set “Does the amount include GST?” to Yes. The calculator then works backwards with the inclusive formula to give you the taxable value and the tax within it.

GST Amount = (Value of supply × GST%) ÷ 100, and the price to charge is the value of supply plus that amount.

  • Leave the inclusive toggle on Yes to work backwards out of the total
  • Read off the taxable value and the tax hidden inside the amount

What is a reverse GST calculation?

A reverse, or inclusive, GST calculation starts from a gross amount and works out how much of it is tax. It is the calculation you need whenever the figure in front of you is an MRP, a receipt total, or any price a customer has already been quoted.

Reverse GST formula

  • Extracting GST from an inclusive amount

    A. Taxable value = Total amount × {100 ÷ (100 + GST rate)}

    B. GST Amount = Total amount – Taxable value

    On an intra-state sale that GST amount splits equally into CGST and SGST; on an inter-state sale it is all IGST.

Reverse GST example

An invoice total of ₹1,18,000 at 18% GST:

  • Taxable value = ₹1,18,000 × (100 ÷ 118) = ₹1,00,000
  • GST Amount = ₹1,18,000 – ₹1,00,000 = ₹18,000
  • Intra-state: CGST ₹9,000 + SGST ₹9,000

When you need it

  • Working out the tax inside an MRP before raising a tax invoice.
  • Reconciling a gross receipt against a supplier's invoice.
  • Checking that a quoted all-in price carries the rate you expect.

Frequently Asked Questions

MRP is inclusive of GST, so use the reverse formula: taxable value = MRP × 100 ÷ (100 + rate), and the GST is the difference. At 18%, that is MRP × 100 ÷ 118.

GST Amount = Value of supply – [Value of supply × {100 ÷ (100 + GST%)}]. That is what this calculator does when the inclusive toggle is set to Yes.

No. Reverse GST here means extracting tax from an inclusive amount. Reverse charge mechanism is a separate provision where the recipient, not the supplier, is liable to pay the tax.

Because the reverse calculation divides by 100 plus the rate. Only totals that are exact multiples of (100 + rate) reduce to round taxable values — ₹1,18,000 at 18% does, ₹1,00,000 at 18% does not.
