Tax Invoice Template
Sales tax compliance is one of the most complex obligations facing businesses today, and it becomes even more challenging when your billing documentation is not structured to handle it correctly. A tax invoice template is specifically designed to ensure that your sales tax is calculated, displayed, and documented in a manner that satisfies both your client's accounts payable requirements and the reporting requirements of your state, provincial, or national tax authority. Getting your tax invoice right is not optional—it is a legal requirement that protects your business, your clients, and your standing with tax authorities.
Eonebill's free tax invoice template takes the guesswork out of tax-compliant billing. It includes clearly labeled fields for your tax identification number, the client's tax ID (for B2B transactions), itemized tax rates and amounts, and a professional layout that makes tax breakdown transparent and easy to verify. Whether you operate in a single-tax-state like Oregon or Montana, or you are navigating the multi-state complexity of the United States, our template adapts to your specific tax situation.

What Is a Tax Invoice?
A tax invoice is an invoice that contains the specific information required by a tax authority for VAT, GST, or sales tax purposes. While a standard invoice serves as a commercial record between buyer and seller, a tax invoice additionally serves as a legal instrument that documents the collection and remittance of indirect taxes. It is the document that enables businesses to claim input tax credits, allows tax authorities to audit transactions, and gives buyers the evidence they need to support their own tax deductions.
The key differentiator between a standard invoice and a tax invoice is the level of tax detail. A standard invoice might show a single tax amount at the bottom of the document. A tax invoice must show:
- The seller's tax identification number
- The buyer's tax identification number (in many jurisdictions, particularly for B2B transactions)
- The tax rate or rates applied
- The taxable amount at each rate
- The tax amount charged at each rate
- Whether any items are exempt from tax and why
Tax invoices are mandated in most jurisdictions for any business that is registered to collect and remit sales tax, VAT, or GST. The specific rules vary by jurisdiction, but the underlying principle is consistent: whenever a taxable supply is made and tax is collected, a proper tax invoice must be issued.
United States: Sales tax is levied at the state and local level. A sales tax invoice must show the total amount paid, the tax rate applied, and the seller's sales tax permit number. Some states require additional information, such as the buyer's D.M.V. number for vehicle sales.
European Union: VAT invoices are governed by EU Directive 2006/112/EC and must include the seller's VAT ID, the buyer's VAT ID (for B2B transactions), the VAT rate and amount for each rate category, and a description of the goods or services.
Canada: GST/HST invoices must include the seller's business number, the GST/HST rate and amount, and—for supplies over $30—must be in writing and contain sufficient detail to identify the transaction.
How to Create a Tax Invoice
Creating a tax-compliant invoice using Eonebill's free template involves several important steps beyond those of a standard invoice.
Step 1: Determine Your Tax Registration Requirements
Before you can issue a tax invoice, you must be registered for tax collection in your jurisdiction. In the U.S., this means obtaining a Sales Tax Permit from each state where you have sales tax nexus. In the EU, this means registering for VAT with your local tax authority. In Canada, it means registering for GST/HST with the Canada Revenue Agency.
Step 2: Identify the Correct Tax Rates
Tax rates vary by product or service category, not just by jurisdiction. Many states exempt certain items from sales tax, such as groceries, prescription medications, or professional services. Some items may be subject to a reduced tax rate. Make sure you are applying the correct rate to each line item on your invoice.
Step 3: Classify Items by Taxability
Organize your line items by taxability. Group taxable items together and exempt items together. This organization will be reflected in the tax calculation section of your template.
Step 4: Enter Tax Identification Numbers
Fill in your tax ID (EIN, VAT ID, or Business Number) in the designated field. For B2B transactions where the buyer is registered for tax, also enter the buyer's tax ID number. In many jurisdictions, a B2B sale to a registered business is zero-rated or exempt, so the buyer's ID is critical for them to claim input tax credits.
Step 5: Calculate Tax by Rate Category
For each tax rate that applies to your sale, calculate the taxable subtotal and the tax amount. Show these separately in the tax breakdown section. For example:
- Taxable subtotal at 7%: $5,000.00 → Tax: $350.00
- Taxable subtotal at 6.5%: $2,000.00 → Tax: $130.00
- Exempt items: $500.00 → Tax: $0.00
Step 6: Present the Grand Total
The grand total should reflect the sum of all line items plus all taxes. Show the tax components clearly so the buyer can verify the tax being charged.
Step 7: Review Against Local Requirements
Before sending, review the invoice against your specific jurisdiction's requirements. Eonebill's template covers the most common fields, but some industries or products may have additional requirements.
Key Elements of a Tax Invoice
Seller's Tax Identification Number: This is your registered tax number (EIN, VAT ID, BN) that identifies your business to the tax authority.
Buyer's Tax Identification Number: Required for B2B transactions in most jurisdictions. Allows the buyer to claim input tax credits.
Invoice Number: A unique, sequential identifier for the invoice.
Date of Supply (Tax Point): In many tax systems, the tax point is the date when the supply was made, not the invoice date. Some jurisdictions allow the invoice date to serve as the tax point.
Description of Goods or Services: A clear description sufficient for the tax authority to determine the nature of the supply.
Quantity and Unit Price: Standard invoice elements.
Taxable Amount: The amount subject to tax at each applicable rate.
Tax Rate(s): The percentage rate(s) of tax applied.
Tax Amount: The calculated tax amount at each rate.
Total Tax Amount: Sum of all tax amounts.
Total Amount (Including Tax): The grand total including all taxes.
Currency: Clearly state the currency.
