What GST Does to Your Price
GST is a consumption tax: the end customer bears it, while a GST-registered seller collects it and accounts for it to IRAS. The current GST rate in Singapore is 9%, according to IRAS. For a dropshipped home goods order, that tax affects the amount the customer pays, the amount you remit, and the margin you should analyse (Source: Inland Revenue Authority of Singapore).
Registration can also change your effective product cost. A registered seller can generally recover eligible GST paid on business purchases as input tax. An unregistered seller cannot recover that amount, so supplier GST, eligible service GST and other tax-bearing costs remain part of the cost base. Do not treat GST collected from customers as revenue or GST recoverable from suppliers as profit.
For illustration only, assume a product costs 50 before GST and the selling price is 100 before GST. At 9%, a registered seller collects 9 and may recover 4.50 of eligible input GST, leaving a pre-advertising margin of 50. An unregistered seller selling for 100 has a 54.50 tax-inclusive cost, leaving 45.50 before advertising. Use the product pricing calculator to test the difference.
| Measure | GST-registered seller | Unregistered seller |
|---|---|---|
| Customer price before GST | S$100 | S$100 |
| GST collected | S$9 | S$0 |
| Effective product cost | S$50 | S$54.50 |
| Margin before advertising | S$50 | S$45.50 |
Registration, Imports and Cross-Border Orders
A Singapore-registered dropshipper must account for GST on taxable sales and should build the tax into its pricing and cash-flow review. IRAS says a Singapore business must register when taxable turnover for a calendar year exceeds $1 million, or when it expects taxable turnover of more than $1 million in the next 12 months. A registered seller can also need to confirm whether GST paid on imported stock is recoverable, based on the import and business records.
An unregistered seller generally does not charge GST as a separate line. That does not make imported goods tax-free: GST or other border charges may still arise when products enter Singapore. For a cross-border order, identify who is the importer, who pays the carrier or customs authority, and whether a marketplace or supplier has already collected tax. Do not assume the checkout tax treatment is correct without checking the shipment terms.
Low-value-goods treatment may change the collection point. IRAS defines low-value goods as goods with a sales value of S$400 or below imported into Singapore by air or post; a GST-registered overseas supplier charges GST at the point of purchase. Confirm whether the supplier is registered, whether the goods meet that definition, and whether the order is shipped by air or post. For a pricing check, compare the customer price, supplier charge, import tax and delivery cost in the product pricing calculator, then validate the GST position with IRAS or an adviser.
| Model | Main question to confirm | What to measure |
|---|---|---|
| Singapore-registered seller | Is GST being charged and accounted for on the taxable sale? | Net sales, GST collected and import-related tax |
| Unregistered seller | Is GST being shown incorrectly, and who bears import charges? | Delivered order cost and margin after border charges |
| Overseas supplier or cross-border order | Does low-value-goods treatment apply, and who collects GST? | Checkout tax, shipment terms and destination |
Worked example with sample numbers
This example is illustrative. It uses sample numbers for a dropshipping home goods store selling in Singapore. They are made up to show the method, they are not a benchmark, and your own figures will differ.
Formula: Tax inside an inclusive price = price - price / (1 + tax rate).
| Approach | Customer sees | Tax inside | You keep before costs |
|---|---|---|---|
| Tax included in the price | S$49.99 | S$4.13 | S$45.86 |
| Tax added at checkout | S$54.49 | S$4.50 | S$49.99 |

Inclusive and Exclusive Prices
A GST-inclusive price is the total the customer pays, with GST already built in. This is usually clearer for a consumer-facing Shopify store selling home goods: the product page, cart and checkout show one final amount. A GST-exclusive price shows the product amount first, then adds GST on the invoice or at checkout. It can be useful for wholesale quotes, business buyers or internal cost-plus pricing, but the final customer payment must still be clear.
At Singapore’s 9% GST rate, the amount you retain is the sale value before GST, not the full amount collected. For an inclusive price, extract GST by multiplying the customer price by 9/109. For an exclusive price, add 9% to the stated price. Use the product pricing calculator to test both presentations before setting a storefront price (Source: Inland Revenue Authority of Singapore).
| Pricing presentation | Customer price | GST component | Amount retained before costs |
|---|---|---|---|
| GST-inclusive | Displayed price | Displayed price × 9/109 | Displayed price × 100/109 |
| GST-exclusive | Base price × 1.09 | Base price × 9% | Base price |
How to Read the Worked Example
Read the worked computation from the customer’s payment downward. Start with the listed selling price and identify whether it is GST-inclusive or GST-exclusive. If GST is included, separate the tax portion from the amount retained as sales revenue; GST collected is not product profit. If the price is exclusive, check that the GST added at checkout is not accidentally counted again in revenue.
Next, follow each deduction by purpose. Supplier or platform charges reduce the amount available from the order, but keep them labelled separately from GST. Import freight, duties and other landed costs belong in the product’s delivered cost when they are costs you bear. Import GST needs its own treatment in your records: do not automatically treat every tax payment as either a permanent expense or recoverable tax without checking the transaction and your GST treatment.
The final margin is meaningful only when its numerator and denominator are clear. Gross margin compares revenue with product and directly related fulfilment costs; a margin after advertising also includes the advertising cost assigned to that order or product. Use the first to assess product economics and the second to decide whether customer acquisition is supportable. For a second check, enter the same assumptions in the product pricing calculator, keeping the customer price, GST, costs and margin measures separate.
| Line | What to check | Why it matters |
|---|---|---|
| Selling price | Inclusive or exclusive of GST | Defines the revenue base |
| GST | Collected tax, not ordinary profit | Prevents overstating margin |
| Supplier or platform charges | Order cost or selling fee | Shows what the sale actually costs |
| Import costs | Freight, duties and import GST identified separately | Clarifies landed cost and tax treatment |
| Margin | Which costs are included | Determines the decision the measure supports |
Records Worth Keeping
Keep two linked record sets: evidence for GST reporting and operating data for margin analysis. For each order, retain the order number, date, customer location, items, price, GST treatment, refund or cancellation status, and the tax invoice or credit note where applicable. Payment-gateway and Shopify settlement records should reconcile to the order total, refunds, and payout received.
For purchases, keep supplier invoices, product-cost records, import permits or customs documents, freight charges, and proof of payment. These support the GST treatment of purchases and imports; do not rely only on a supplier spreadsheet. Retain platform-fee invoices and settlement statements separately, because fees affect net margin even when they are not part of the customer’s taxable sale. Keep inventory receipts, stock adjustments, remaining units, and landed-cost assumptions to explain inventory value and cost of goods.
Tax records establish what was charged, paid, imported, or refunded. Operating records help decide what to sell or stop: contribution after advertising, product and collection profit, return rate, dead stock, and remaining stock value. ORVX can sync Shopify orders, products, and customers and show these profitability measures; reconcile its reports to your saved invoices, import documents, payment records, and platform statements.
