Sales Tax vs VAT vs GST: A Guide for Global SaaS Founders
Anyway Team
· 7 min read ·
Sales tax, VAT, and GST are consumption taxes, but they are administered differently. US sales tax is generally imposed by state and local rules at the final sale. VAT is collected through stages of the supply chain with credits for tax paid on business inputs. GST is a VAT-style consumption tax used under that name in countries such as Canada, Australia, and Singapore.
For SaaS, the result depends on where the customer is, whether the buyer is a business or consumer, how the product is classified, and who is the legal seller.

This table is an orientation, not a substitute for advice based on a specific entity, product, and customer base.
What is sales tax?
Sales tax in the United States is mainly governed at the state and local level. There is no single federal sales-tax system for SaaS.
A state may tax SaaS, exempt it, or apply different treatment according to how the product is delivered and used. A seller can create an obligation through physical presence or economic activity that passes a state threshold. Local rates can also affect the amount charged to the buyer.
A direct SaaS seller may need to answer:
Is this product taxable in the customer’s state?
Has the business created a registration obligation there?
Which address evidence determines the customer location?
Does the buyer have a valid exemption?
Which state and local rate applies?
When is the return due?
How are refunds reflected in the next filing?
The answers can differ from one state to another.
What is VAT?
Value-added tax is charged on consumption and collected at stages of the supply chain. A registered business generally charges output VAT on taxable sales and may claim eligible input VAT under the applicable rules.
For cross-border digital services, place-of-supply and customer-status rules are central. A consumer sale may require tax based on the customer’s country. A business purchase may receive different treatment when the buyer supplies valid registration information and the relevant reverse-charge rule applies.
Invoices also matter. European Commission guidance states that EU rules generally require invoices for many business-to-business supplies and some business-to-consumer transactions, while exact national requirements can vary. Seller and customer details, invoice date and number, description, taxable amount, tax rate, tax amount, and reverse-charge wording are among the fields that can be required.
What is GST?
Goods and services tax is another name used for a broad consumption-tax system. Its mechanics often resemble VAT, but registration thresholds, rates, invoice requirements, and digital-service rules belong to each country.
Canada’s digital-economy guidance, for example, explains GST/HST rules that can apply to digital-economy businesses selling to Canadian consumers. Australia and Singapore use their own GST systems and definitions. Founders should not copy a VAT setup into a GST market without checking the local rules.
The shared lesson is simple: “GST” does not mean one worldwide registration or one worldwide rate.
Why SaaS tax depends on the buyer
The same subscription can receive different tax treatment when sold to two customers.
Customer location
Digital-service rules often use the customer’s location rather than the seller’s server location. Checkout may need reliable location evidence such as billing details and payment information, according to the applicable rules.
Business or consumer status
A business buyer may provide a valid tax registration number. In some VAT systems, that can support reverse-charge treatment. A consumer purchase is more likely to require the seller to collect local tax at checkout.
Product classification
Downloaded software, remotely accessed SaaS, human-delivered consulting, online education, and marketplace services can be classified differently. Describe the product accurately before assigning a tax code.
Seller obligation
Registration may depend on thresholds, transaction counts, physical presence, or special rules for overseas digital sellers. A calculation tool needs the seller’s registrations and product data before it can return the right result.
Direct seller vs Merchant of Record
The legal-seller model determines who performs the transaction-tax work.
Direct SaaS seller
The SaaS company sells to the customer and remains responsible for its registrations, calculation settings, collection, invoices, filings, and records. Payment and tax software can help perform those tasks.
Merchant of Record
The MoR becomes the seller for covered customer transactions. It calculates and collects applicable sales tax, VAT, or GST, files it under the MoR arrangement, and issues the customer transaction document. The SaaS company receives net revenue and continues to account for its own business income.

How Anyway handles transaction tax
Anyway states that it is Merchant of Record for covered sales through Anyway Business. It calculates, collects, and files applicable sales tax, VAT, and GST, and connects that work with hosted checkout, invoices, receipts, orders, subscriptions, and payouts.
The current public price is 3.9% + $0.50 per successful transaction, with no monthly fee and no setup fee.
For a founder, the customer flow is:
Publish an approved SaaS or digital product.
Send the buyer to the Anyway payment link.
Let checkout apply the transaction treatment for the sale.
Verify the paid order on the server.
Deliver the product or activate the subscription.
Reconcile net revenue and payouts through the order and Finance records.
This gives the transaction one seller and one connected payment-and-tax record.
A tax checklist for global SaaS
1. Describe the product precisely
Write one sentence explaining what the customer receives and whether delivery is automated. Use the same description on the website and merchant application.
2. Decide who will be the seller
Choose between direct selling and an MoR before assembling tax tools. That decision assigns the main transaction duties.
3. Collect only the data the tax flow requires
The checkout needs enough information to determine location and customer status under the applicable rules. Keep the data model purposeful and secure.
4. Make business-buyer fields clear
If business tax information can change the treatment, collect it in the provider’s supported format and validate it through the proper workflow.
5. Keep customer documents with the order
An invoice or receipt should be linked to the payment, seller, customer, product, currency, tax, and refund history. Read SaaS invoices and receipts for a field checklist.
6. Reconcile tax and refunds
A refund can change the taxable amount and the merchant balance. Match the original order and later adjustment instead of treating them as unrelated entries.
7. Review new markets as sales grow
Tax rules and product coverage change. Check official guidance and professional advice when the business adds a country, entity, marketplace model, or materially different product.
Do not treat the tax name as the whole rule
Sales tax, VAT, and GST all tax consumption, but the registration test, customer evidence, rate, invoice, return, and record rules differ. A correct setup begins with the buyer, product, seller, and jurisdiction.
Anyway gives global SaaS founders a direct way to put applicable transaction-tax handling inside the sale, with the same MoR responsible for checkout, customer documents, orders, and merchant payout.
Frequently asked questions
Is VAT the same as sales tax?
No. Both are consumption taxes, but VAT is collected through stages of the supply chain, while US sales tax is generally imposed at the final taxable sale under state and local rules.
Is GST the same as VAT?
GST often uses a VAT-style structure, but each country has its own registration, rate, invoice, filing, and digital-service rules.
Is SaaS always taxable?
No single answer applies worldwide. Taxability depends on jurisdiction, product classification, customer type, customer location, and seller obligation.
Who pays VAT on a SaaS subscription?
The buyer may pay VAT as part of the checkout total, while the legal seller collects and files it. Business-buyer and reverse-charge rules may change the treatment.
Does Anyway handle sales tax, VAT, and GST?
Anyway states that it calculates, collects, and files applicable sales tax, VAT, and GST as Merchant of Record for covered sales.
Does using an MoR remove business-income reporting?
No. The MoR handles transaction tax for covered customer sales. The founder or company still keeps payout and income records under the rules that apply to it.
