Understanding Gross Sales for Online Sellers
If you're selling on Shopee, Lazada, TikTok Shop, or doing live selling on Facebook and Instagram, understanding how the Bureau of Internal Revenue (BIR) calculates your gross sales is crucial for tax compliance. This guide breaks down everything you need to know about gross sales basis for online sellers in the Philippines.
What Are Gross Remittances?
According to BIR Revenue Regulation No. 16-2023, gross remittances refer to the total amount that e-marketplace operators like Shopee, Lazada, and TikTok remit to online sellers.
What's Included in Gross Sales
Gross remittances include total sales value of products sold, shipping fees collected from customers (if remitted to seller), platform fees deducted by the marketplace, and any other payments related to your sales transactions.
Important Note
Gross remittances are calculated BEFORE deducting your costs of goods sold, operating expenses, or other business deductions. This is different from your net income or taxable income.
The P500,000 Threshold: Exemption vs. Taxation
Exempt from Withholding Tax:
Online sellers with annual gross remittances NOT exceeding P500,000
You can continue selling without immediate BIR registration for withholding tax purposes
However, you may still need to register if you exceed other income tax thresholds
Subject to 1% Withholding Tax:
Sellers whose gross remittances EXCEED P500,000 within a taxable year
The withholding applies on HALF of your gross remittances (effectively 0.5%)
E-marketplace operators will automatically withhold this tax once you exceed the threshold
How Different Platforms Calculate Gross Sales
Shopee Sellers
Shopee calculates your gross remittances based on:
- Total order value from all completed transactions
- Shipping fees (if applicable)
- Voucher discounts applied by Shopee (still counts as gross sales)
- Returns and cancellations are deducted from total
Lazada Sellers
Lazada's gross remittance calculation includes:
- Total sales from all successful orders
- Shipping fees collected and remitted
- Platform service fees (deducted before remittance)
- Promotional discounts sponsored by Lazada
TikTok Shop Sellers
For TikTok Shop, gross remittances cover:
- Total value of products sold through live streams and videos
- Affiliate commissions (if applicable)
- Platform fees
- Any bonuses or incentives from TikTok
Live Sellers (Facebook, Instagram)
For social media live sellers, gross sales include:
- Total value of products sold during live sessions
- Payment received through GCash, Maya, bank transfers
- Shipping fees collected
- Any platform-specific fees (if using selling tools)
When Does Withholding Tax Start?
The 1% withholding tax obligation begins in three scenarios:
Upon exceeding P500,000 threshold
When your cumulative gross remittances exceed P500,000 at any point during the year
Failure to submit Sworn Declaration
If you don't submit the required BIR-received Sworn Declaration (SD) within the prescribed period
Platform determination
When the e-marketplace operator determines your gross remittances have exceeded P500,000
Important Note
Once you exceed the threshold, withholding tax applies only on the amount that exceeds P500,000, not on your entire gross sales.
Gross Sales vs. Net Income: Key Differences
Many online sellers confuse gross sales with net income. Here's the difference:
Gross Sales (Gross Remittances):
- Total revenue from sales BEFORE any deductions
- Used by BIR to determine withholding tax eligibility
- Includes all fees, shipping, and platform charges
Net Income (Taxable Income):
- Gross sales MINUS cost of goods sold
- MINUS operating expenses (shipping, packaging, marketing)
- MINUS allowable business deductions
- Used to calculate your income tax liability
Example:
- Gross sales: P600,000
- Cost of goods sold: P300,000
- Operating expenses: P100,000
- Net taxable income: P200,000
Registration Requirements
If your gross remittances exceed P500,000, you must:
Register with BIR
as a self-employed individual or business entity
Obtain a Tax Identification Number (TIN)
if you don't have one
Submit a Sworn Declaration (SD)
to the e-marketplace operator
Provide certification of exemption
if you qualify for tax incentives
Issue official receipts or sales invoices
for every transaction
Record-Keeping Requirements
To properly track your gross sales and stay compliant, maintain records of:
- Daily sales transactions from each platform
- Bank statements showing remittances
- Platform-generated sales reports
- Shipping and delivery records
- Customer invoices and receipts
- Expense receipts and proofs of payment
Tip
Use accounting software or spreadsheets to consolidate sales from multiple platforms into one system.
Common Mistakes to Avoid
Mistake 1: Not tracking gross sales across platforms
Many sellers forget to combine sales from Shopee, Lazada, and TikTok. The P500,000 threshold applies to TOTAL gross remittances from ALL platforms.
Mistake 2: Confusing gross sales with net income
Some sellers think they only need to register when they make a profit. Registration is based on gross sales, not net income.
Mistake 3: Ignoring platform fees
Platform fees are part of gross remittances. Don't deduct them when calculating your threshold.
Mistake 4: Late registration
Registering after exceeding P500,000 may result in penalties. Proactive registration is always better.
Mistake 5: Not keeping proper records
Without records, you can't prove your gross sales if audited. Keep all platform reports and bank statements.
