If you're running a SaaS business in the Philippines, tax filing isn't just about paying—it's about maximizing deductions legally.

This updated guide now includes:

SaaS-related expenses
Rental and internet expenses
What needs to be under the business name to be valid

STEP 1: Record Your Income

Record ₱50,000 in your Books of Accounts

Use:

Cash Receipts Journal OR
General Journal

STEP 2: Identify Your Tax Type

Non-VAT (3%)

₱50,000 × 3% = ₱1,500

VAT (12%)

₱50,000 + ₱6,000 VAT

STEP 3: Check Withholding Tax

Ask for BIR Form 2307

This reduces your tax later

STEP 4: File Business Tax

Non-VAT → 2551Q

Percentage Tax Return

VAT → 2550Q

VAT Return

STEP 5: File Income Tax

Sole → 1701Q

Quarterly Income Tax Return for Individuals

Partnership / OPC → 1702Q

Quarterly Income Tax Return for Corporations

STEP 6: Record ALL Expenses (Including SaaS, Rental, Internet)

This is critical to reduce your taxable income.

✔ Common SaaS + Operational Expenses

Domain (Namecheap, GoDaddy)
Hosting (AWS, Vercel)
Email tools (Google Workspace)
APIs / SaaS tools
Developer tools
Marketing ads

✔ Additional Deductible Expenses (IMPORTANT)

1. Rental Expense

Office space
Co-working space
Even home office (portion only)

💡 Requirement:

Lease contract OR receipt
Must ideally be under business name

2. Internet Expense

Fiber, broadband, prepaid WiFi

💡 Important Rule:

Should be under business name
OR at least supported with:
Billing statement
Proof it's used for business

3. Utilities (Optional)

Electricity (if office-based)
Can be partially allocated for home office

⚠️ VERY IMPORTANT RULE

For expenses to be fully valid and safe during audit:

👉 They should be:

Under registered business name
With official receipt (OR) or invoice

If NOT under business name:

Still usable, BUT higher risk during audit
Best practice: migrate subscriptions to business name

STEP 7: Sample Expense Computation (Updated)

Scenario:

Income:

₱50,000

Expenses:

Domain → ₱1,000
Hosting → ₱5,000
Email tools → ₱1,500
Rental → ₱8,000
Internet → ₱2,000

👉 Total Expenses = ₱17,500

Net Income: ₱50,000 – ₱17,500 = ₱32,500

STEP 8: Apply Tax

Percentage Tax:

₱50,000 × 3% = ₱1,500

Income Tax:

Based on ₱32,500 (NOT ₱50,000)

👉 This is where you save money.

STEP 9: ISSUE THE CORRECT INVOICE OR RECEIPT (VERY IMPORTANT)

This is where many SaaS founders make mistakes.

A. For Local Clients (Same City or Nearby)

👉 Issue:

Official Receipt (OR) for services
OR Sales Invoice (new BIR system allows both depending on registration)

Include:

Client name
Address
TIN (if business)
Description of service

B. For Clients in Other Cities/Provinces (Within PH)

👉 Same rule as local clients

💡 Important:

Location does NOT change the document type

You still issue:

OR or Invoice

C. For Overseas Clients (Foreign Clients)

👉 Issue:

Sales Invoice (recommended)
OR Official Receipt (if service-based)

Include:

Client company name
Country (e.g., USA, UK, Singapore)
Address (if available)

💡 Special Rule for Overseas SaaS Clients

Usually zero-rated VAT (if VAT-registered)

Or treated as export of services

👉 Requirements:

Payment proof (PayPal, Wise, Stripe)
Contract or agreement

D. When to Use Invoice vs Receipt

Type	When to Use
Sales Invoice	For goods OR SaaS billing (recommended standard)
Official Receipt	For pure service transactions

💡 Trend (BIR update):

👉 Many businesses now use Sales Invoice for everything

E. Digital / SaaS Billing Best Practice

If using:

Stripe
PayPal
SaaS subscription billing

👉 Still:

You must issue your own BIR-compliant Invoice

STEP 10: Pay Tax
