Many business owners in the Philippines are still confused about whether to issue a Sales Invoice or an Official Receipt, especially after the changes introduced under the Ease of Paying Taxes (EOPT) Act. This confusion is common among service providers, small businesses, and growing companies trying to stay compliant with BIR requirements.

Since the EOPT regulations were released in April 2024, the focus has shifted from understanding the change to proper implementation and compliance.

This guide explains the difference between a Sales Invoice and an Official Receipt, when to issue each, and what businesses need to do today to stay compliant.

The Ease of Paying Taxes (EOPT) Act, signed on January 5, 2024, modernizes and simplifies tax administration in the Philippines, making it more taxpayer-friendly.

This regulation outlines amendments to our tax system, including the reclassification of businesses, easier tax return filing, and simplified value-added tax (VAT) rulings.

Watch this to learn more about the EOPT Law and other recent tax changes in the country:

In addition, the EOPT Act involves significant changes to the invoicing requirements, pushing businesses to now use invoices instead of official receipts (ORs).

The Bureau of Internal Revenue (BIR) also released the following memoranda—RR 7-2024 and RR 11-2024—to provide more clarification on this transition.

Before the EOPT Act took effect on April 27, 2024, companies could use official receipts or invoices depending on the nature of their business.

Businesses selling goods and properties use invoices as their primary documents, while those selling services or leasing properties use official receipts.

However, the EOPT Act has amended the use of these documents.

Here are the key differences between official receipts and invoices:

According to the EOPT Act, businesses should now issue invoices as the primary document for selling goods and services.

Also, it’s worth noting that an invoice doesn’t just refer to a sales invoice. Businesses can add any descriptive name to label their invoices, such as “Cash Invoice,” “Credit Invoice,” “Service Invoice,” “Billing Invoice,” and more.

On the other hand, official receipts are only secondary and optional. If your business still decides to use ORs, you must register them to the BIR as a supplementary document to get a new Authority to Print (ATP).

Under the EOPT Act, businesses must use invoices as proof of their sales, regardless of whether customers pay in cash or on credit. If the customer pays in credit, meaning the business collects the payment later, business owners should not issue a second invoice upon collection.

Instead, businesses can issue an official receipt as proof or acknowledgment of payment once the customer settles their outstanding balance.

If you want to take advantage of tax-deductible expenses, remember that invoices are considered valid documents for tax deductions.

Moreover, VAT-registered businesses can now use the invoices they receive as input VAT when buying from other VAT-registered companies.

Meanwhile, official receipts are no longer valid when claiming a tax-deductible expense or input VAT.

Since the release of the EOPT Act, many businesses are still adjusting to the new invoicing rules. To help clarify what applies today, this section addresses the most common questions about Sales Invoices, Official Receipts, and proper invoicing compliance.

Invoices are categorized based on VAT status: VAT invoices for taxable sales and Non-VAT invoices for exempt or non-VAT transactions. Each must show the correct breakdown of VATable, zero-rated, and exempt sales.

The BIR defines an invoice as a written account evidencing the sales of goods and services issued to customers. There are also two categories of invoices as follows:

If you’re a VAT-registered business selling zero-rated or VAT-exempt products, note that you can use a single invoice for mixed transactions, including goods/services subject to VAT, Zero-rate, and VAT-exempt sales.

When doing so, it’s essential to show a breakdown of the amounts for each type of sale: VATable sales, VAT amount, VAT-exempt sales, and zero-rated sales.

VAT-registered businesses must issue an invoice for every sale, regardless of amount. Non-VAT businesses must issue an invoice when the sale exceeds ₱500, the buyer requests it, or total daily sales under ₱500 exceed ₱500.

The timing of when to issue an invoice depends on whether you’re VAT-registered and the amount involved in the transaction.

VAT-registered sellers should always invoice all sales transactions, regardless of the amount.

Meanwhile, non-VAT-registered businesses must issue an invoice when they meet at least one of these three conditions:

• The single transaction amount exceeds ₱500
• The buyer asked for an invoice, regardless of the amount
• If the total of all transactions under ₱500 exceeds the ₱500 threshold by the end of the day

Also, note that the BIR will adjust the ₱500 threshold every three years based on the Consumer Price Index.

Unused Official Receipts can still be used as supplementary proof of payment, or they can be converted into invoices by striking out “Official Receipt” and stamping “Invoice.”

If you still have unused booklets of official receipts in your hand, don’t throw them away! Even though invoices are now the primary document, you still have two options for utilizing your unused receipts until they’re fully consumed.

The first option is to use your remaining receipts as supplementary documents for your business. If you still issue an invoice for the same transaction, you can issue a receipt to acknowledge your customer’s payment.

If opting for the first option, stamp the OR with the words “THIS DOCUMENT IS NOT VALID FOR CLAIM OF INPUT TAX.” Doing so reminds buyers that they can’t use ORs to claim input tax.

The second option is to convert unused receipts into invoices, which is very beneficial for businesses that have yet to print their invoices.

To do this, just strike out the words “Official Receipt” in your OR and stamp it with “Invoice,” “Sales Invoice,” “Cash Invoice,” or any other variation that includes the word “Invoice”.

Additionally, you must report the inventory of unused receipts to the BIR to be converted to invoices.

Businesses with CRM or POS systems can replace “Official Receipt” with “Invoice” in their system without prior BIR approval, but must report the starting invoice serial number to the BIR.

If your business uses cash register machines (CRM) and point-of-sale (POS) machines, you can simply replace “Official Receipt” with “Invoice” in your systems without notifying the BIR.

However, these businesses must still submit a notice to the BIR specifying the invoice’s starting serial number, which should follow the serial number of the last issued OR.

Yes. Online sellers using e-receipting or e-invoicing software must issue invoices instead of traditional receipts and report their starting serial number to the BIR.

Similar to the new withholding tax rule, the recent changes in invoicing regulations are also applicable to online sellers.

Although online sellers don’t use CRM or POS, they typically rely on e-receipting or e-invoicing software to issue their sales documentation. Like businesses using CRM and POS, online sellers can replace “Official Receipt” with “Invoice” in their software.

Additionally, they must report to the BIR the starting serial number of their invoice, following the same procedure as those with CRM and POS.

Businesses using computerized accounting systems or computerized books of account must ensure their system configuration complies with current BIR invoicing rules and that any system changes are covered by an approved CAS or CBA application.

If your business uses a computerized accounting system (CAS) or computerized books of account (CBA), you should reconfigure your systems and file for a new application to use CAS or CBA.

Filing a new application involves surrendering your current Acknowledgement Certificate (AC) or Permit to Use (PTU) and applying for a new one.

The BIR previously required affected businesses to complete CAS or CBA updates by December 31, 2024. While this transition period has passed, businesses that updated or modified their systems must ensure their CAS or CBA is properly reconfigured and covered by an approved BIR application.

A compliant invoice must include the seller’s TIN, registered business name and address, invoice label and serial number, buyer details, itemized goods/services, VAT breakdown (if applicable), and total amount.

Now that invoices are the primary document for proof of sales, businesses should secure an Authority To Print (ATP) from the BIR before going to an Accredited Printer to print their invoices.

Here are the following information to include in your invoice format:

• Taxpayer’s registered name
• Statement that the seller is VAT or Non-VAT registered, TIN, and branch code
• Registered business address
• “Invoice” label
• Space for buyer’s information
• Serial number
• Quantity, unit cost, description of goods or services
• Total amount of sale, with separate VAT amount, if applicable
• Breakdown of sales, if applicable
• Space for details of customers who are senior citizen/s, person/s with a disability, national athletes and coaches, solo parents, and Medal of Valor awardees
• Additional information based on guidelines for manual and system-generated invoices

Failing to issue the proper invoices, using ORs as primary proof of sale, or incorrect documentation can lead to fines (₱1,000–₱50,000) and even possible imprisonment under BIR rules.

Non-compliance with the new invoicing regulations set by the EOPT Act, such as non-issuance of invoices, failing to stamp an OR, and the like, is subject to a penalty of ₱1,000 to ₱50,000.

In addition, non-compliant business owners may be imprisoned for two to four years.

Yes. While the core invoicing rules introduced in 2024 remain in effect, the major focus in 2026 is on electronic invoicing (e-invoicing) compliance and proper implementation.

In 2026, businesses are expected to move beyond understanding the invoicing rules and focus on how invoices are issued, recorded, and transmitted.

Selected taxpayers, particularly e-commerce sellers, large taxpayers, and businesses using computerized accounting systems, are required to comply with BIR e-invoicing requirements, with deadlines extending through December 31, 2026.

At the same time, businesses must ensure that all invoices, whether electronic or manual, contain the mandatory information and fields required by the BIR.

Using Official Receipts as primary sales documents, issuing incomplete invoices, or failing to comply with e-invoicing requirements can still result in fines or legal penalties.
