Understanding BIR’s Rules on Deductible Business Expenses: What SMEs Need to Know

Running a business in the Philippines comes with its fair share of financial challenges. For many SMEs in the Philippines, every peso matters. Knowing which expenses can be deducted for tax purposes can make a big difference in managing cash flow and ensuring compliance with the Bureau of Internal Revenue (BIR).

Recently, the BIR reiterated the criteria and guidelines on the deductibility of ordinary and necessary expenses under Section 34 (A)(1)(a) of the Tax Code. For SMEs, this isn’t just technical accounting, it’s about making smarter financial decisions that support growth.

In this article, we’ll break down what the circular means, share real-life examples, and show how working with outsourced accounting in the Philippines can help businesses stay compliant while maximizing allowable deductions.

What Does “Ordinary and Necessary” Mean for SMEs?

The BIR defines deductible expenses as those that are:

• Ordinary – Normal, usual and customary in your business
• Necessary – Appropriate and helpful for the development of your operations.
  

For an SME, this translates into everyday costs like:

• F&B businesses: raw materials, packaging, kitchen equipment, salaries of staff.
  
• Digital-ready service providers: software subscriptions, digital marketing costs, professional fees.
  
• Subsidiaries of larger groups: administrative expenses, management fees, and shared services.

Why Does It Matter for Your Business?

Understanding which expenses are deductible allows you to:

• Reduce taxable income legally.
  
• Free up more funds for reinvestment and growth.
  
• Avoid penalties from incorrect reporting.
  

For example, if your SME earns ₱5,000,000 in revenue and has ₱3,000,000 in deductible expenses, your taxable income becomes ₱2,000,000. At the 25% corporate income tax rate, that’s ₱500,000 tax due instead of ₱1,250,000 if deductions weren’t claimed.

Common Deductible Expenses for SMEs

The BIR highlights several categories that SMEs can focus on:

1. Salaries and Wages

• Deductible if properly documented with payroll records and taxes withheld.
  
• Example: A small café with 10 employees paying ₱15,000/month each can claim ₱150,000 monthly as deductible payroll costs.
  

2. Rent and Utilities

• Both office and commercial spaces qualify, provided contracts are in place and taxes are withheld from landlords if required.
  
• Example: A logistics SME renting a warehouse at ₱50,000/month deducts ₱600,000 annually.
  

3. Marketing and Advertising

• For digital-first businesses, online ads and social media campaigns are deductible.
  
• For brick-and-mortar businesses, in-store promotions, posters, and events are valid deductions.
  

4. Depreciation of Equipment

• F&B SMEs can claim deductions for ovens, refrigerators, or delivery vehicles.
  
• Digital businesses can depreciate laptops and IT equipment.

Real-World Scenarios SMEs Face

Scenario 1: Digital-Ready SME Expanding Services

A professional services SME invests ₱120,000 annually in project management and accounting software. With proper documentation, this expense is fully deductible, reducing taxable income and aligning with cloud accounting services adoption.

Scenario 2: Brick-and-Mortar F&B Business

A restaurant spends ₱1,000,000 a year on ingredients and ₱200,000 on marketing. These are deductible, provided they’re supported with official receipts and invoices. If missed, the business risks overpaying taxes by hundreds of thousands.

Scenario 3: Subsidiary of a Larger Group

A subsidiary pays ₱500,000 annually for shared HR and finance services from its parent. With service agreements and invoices in place, this is deductible. Without documentation, the BIR may disallow it.

Documentation: The Key to Compliance

Even if an expense qualifies as ordinary and necessary, the BIR will only allow it if supported by:

• Official Invoices and Vouchers
  
• Withholding tax remittances where applicable.
  
• Contracts, service agreements, or board resolutions for intercompany charges.

For SMEs, missing paperwork is the most common reason expenses are disallowed during audit.
