Common Tax Mistakes Businesses Make
Even with the best intentions, many businesses in the Philippines fall into common tax traps that can cost time and money. Here are the most frequent tax compliance issues:
1. Late Tax Filing
With so much going on in running a business, it’s easy to miss tax filing deadlines sometimes. However, missing these can be costly—and the Bureau of Internal Revenue (BIR) takes them seriously.
According to the National Internal Revenue Code (NIRC) of the Philippines, the following penalties apply for late filing of tax returns with tax due:
- Surcharge: 25% of the tax due
- Interest: 20% per annum on the unpaid amount, starting from the due date until full payment
- Compromise Penalty: Ranges from ₱1,000 to ₱50,000 depending on the unpaid tax amount (based on Annex A of Revenue Memorandum Order No. 7-2015)
For example, if you owe ₱100,000 in taxes and file late, you may be charged:
- ₱25,000 (25% surcharge)
- ₱20,000 (20% interest per annum, prorated)
- ₱15,000 (compromise penalty, based on BIR’s schedule)
This brings the total penalty burden to as much as ₱60,000, which is a substantial hit to any business’s budget.
And it’s not just about penalties. Under Section 255 of the NIRC, willful failure to file returns or pay taxes may lead to criminal charges, punishable by ₱10,000–₱50,000 in fines and imprisonment of 1 to 10 years.
For instance, the deadline for filing the Annual Income Tax Return (BIR Form 1700) for individuals earning purely compensation income is April 15 each year. Filing past this date means you’re automatically subject to the penalties above, regardless of the reason.
2. Incorrect Computation of Tax Dues
Incorrectly computing your tax dues is another common yet critical mistake that can lead to serious consequences. Whether it’s miscalculating your Value-Added Tax (VAT), underreporting income, overstating expenses, or applying the wrong tax rates, these errors raise red flags with the BIR.
These mistakes don’t just happen to small businesses. In fact, the BIR has been increasing its audit efforts across sectors to improve tax collection. In its 2023 annual report, the BIR highlighted intensified tax mapping and audit activities to ensure better compliance from taxpayers.
Under the NIRC:
- Underdeclaration of Income by more than 30% is considered prima facie evidence of fraud, which can lead to:
- 50% surcharge on the tax due (instead of the usual 25%)
- 20% annual interest
- Criminal charges, including fines and imprisonment under Section 255 and 256
For example, if you mistakenly underreport your income by 35%, not only will the BIR assess the tax difference, but they may also add a 50% fraud penalty along with interest. This could easily double what you owe.

3. Incomplete or Disorganized Records
Maintaining accurate and complete records is a legal requirement under the NIRC. Failure to do so can result in:
- Difficulty in substantiating deductions and tax credits, leading to higher tax liabilities
- Potential disallowance of expenses during BIR audits
- Penalties for non-compliance, including fines for failing to maintain books of accounts properly
- Increased risk of audit and investigation by the BIR
All registered taxpayers are required to preserve accounting records such as books of accounts, official receipts, invoices, and other supporting documents for at least 10 years (per RR No. 17-2013).

4. Failure to Withhold the Right Amount of Taxes
Under the NIRC, businesses are required to withhold and remit the correct amount of taxes when making payments subject to withholding—such as compensation, professional fees, rent, or income payments to suppliers. Failure to do so can result in:
- Disallowance of related expenses for income tax purposes
- 25% or 50% surcharge, depending on whether the failure is due to negligence or fraud
- 12% annual interest (under the TRAIN Law) on the unpaid withholding tax
- Compromise penalties or criminal charges under Sections 251, 253, and 255 of the NIRC
- Personal liability of the withholding agent or responsible officers
Even if the income recipient has paid their taxes, the BIR may still hold the withholding agent liable for non-compliance.
5. Ignoring BIR Notices or Audit Letters
Failing to respond to BIR notices, Letters of Authority (LOA), or audit-related correspondences can escalate issues and lead to more severe consequences. Under the NIRC, such inaction may result in:
- Presumptive assessments based on BIR’s best judgment, which may not reflect actual liabilities
- Higher tax assessments due to unrefuted findings
- Additional penalties, surcharges, and interest for failure to comply or submit requested documents
- Possible criminal prosecution for willful neglect or refusal to comply under Section 266 of the NIRC
Businesses are legally obligated to respond to BIR communications within the specified timeframe. Non-compliance signals potential tax evasion or fraud and may trigger more aggressive enforcement actions.
How to Avoid These Tax Mistakes
Avoiding tax compliance errors helps you protect your business from unnecessary costs and legal trouble. Here’s how you can stay on top of your tax obligations in the Philippines:
1. Hire a Qualified Tax Professional
Working with a licensed accountant or tax consultant can help ensure proper filing, accurate computations, and timely submissions. They can also help you interpret updated regulations and assist in handling BIR audits or notices.
2. Use Reliable Accounting Software
Digitizing your bookkeeping can significantly reduce human error. These errors can cost businesses up to $3.1 trillion a year. Modern accounting tools can automate tax computations, track filing deadlines, and generate reports that comply with BIR formats—helping you stay organized and audit-ready.
3. Keep Complete and Organized Records
Maintain proper books of accounts, invoices, receipts, and tax filings for at least 10 years. Develop a system for tracking all your financial documents and train staff to input data accurately.
4. Set Up Internal Controls for Withholding Taxes
Regularly review transactions to ensure correct withholding. Designate a responsible officer for tax compliance and cross-check payments made to employees, freelancers, or suppliers for proper deductions.
5. Respond Promptly to BIR Communications
Never ignore a BIR notice. Always acknowledge and act within the deadline stated. If you’re unsure how to respond, consult your tax advisor immediately to avoid escalating the issue.
6. Stay Updated on Tax Rules and Deadlines
The tax landscape changes frequently. Follow BIR announcements, subscribe to updates, or partner with a professional (like Manila Bookkeepers) who stays on top of regulatory developments for you.
