Home Loan Refinancing and Tax Deductions in the Philippines: What the BIR Actually Allows

If you're refinancing your home loan — or thinking about it — you're probably focused on the monthly savings from a lower interest rate. But there's another financial angle most Filipino homeowners overlook entirely: the tax treatment of refinancing costs and home loan interest under Philippine law.

This guide breaks down exactly what the Bureau of Internal Revenue (BIR) allows, what's deductible, what isn't, and how to document everything correctly so you're fully compliant and not leaving money on the table.

Is Home Loan Interest Tax Deductible in the Philippines?

The short answer: it depends on how you use the property and how you file your taxes.

For Individuals Filing Under the Itemized Deduction Method

Under the National Internal Revenue Code (NIRC) and BIR Revenue Regulations, individual taxpayers who opt for itemized deductions instead of the Optional Standard Deduction (OSD) may deduct interest paid on loans — including home loans — subject to specific conditions.

Key condition: The interest expense must be reduced by an amount equal to 33% of the interest income you earned that year that was subjected to final withholding tax. This is called the "interest arbitrage" rule and it prevents taxpayers from double-benefiting on interest.

Example: If you paid 120,000 in home loan interest in a year and earned 30,000 in bank interest income (subjected to 20% final tax), your deductible interest is reduced by 33% × 30,000 = 9,900. So you can deduct 110,100 instead of the full 120,000.

For Salaried Employees (Pure Compensation Income Earners)

If you earn purely from employment and your employer withholds your income tax, you generally cannot claim itemized deductions — including home loan interest — on your annual tax return. Your tax is computed based on gross compensation with only basic personal exemptions (which were removed under the TRAIN Law). This is the situation for most employed Filipino homeowners.

For Self-Employed Individuals, Freelancers, and Business Owners

If you file your own income tax return and your home is used partly or wholly for business purposes, the interest on your home loan may be deductible as a business expense. You'll need to be able to justify the business use of the property to the BIR. Sole proprietors, professionals, and mixed-income earners are the most likely to benefit here.

Are Refinancing Costs Tax Deductible?

When you refinance, you incur a set of upfront costs — processing fees, appraisal fees, notarial fees, mortgage redemption insurance (MRI), fire insurance, and documentary stamp taxes (DST). Here's how BIR treats these:

Processing and Administrative Fees

These are generally treated as capital expenditures related to acquiring or restructuring a loan. For most individual homeowners, they are not immediately deductible in the year paid. However, self-employed taxpayers and businesses may amortize loan origination costs over the life of the loan as a deferred charge, spreading the deduction across the loan term.

Documentary Stamp Tax (DST) on the New Mortgage

When you refinance, a new mortgage contract is executed, and DST applies. Under Section 195 of the NIRC, DST on mortgage documents is computed at 20 centavos for every 200 pesos (or a fraction thereof) of the loan amount. On a 3,000,000 refinanced loan, that's approximately 3,000 in DST. This is a real out-of-pocket cost — for individual homeowners, it's generally not deductible on a personal return, but for business taxpayers, it may be expensed.

Appraisal Fees

The bank will require a new appraisal of your property. This fee — typically ranging from 3,500 to 8,000 depending on property value and location — is a cost of the refinancing transaction, not a deductible expense for most individual borrowers.

Mortgage Redemption Insurance (MRI) and Fire Insurance Premiums

Insurance premiums paid in connection with a home loan are generally considered personal expenses and are not deductible for employees. For business taxpayers using the property for income-producing purposes, these may be deductible as business expenses.

BIR-Compliant Documentation: What to Keep

Whether or not your specific situation allows deductions, good documentation protects you in case of a BIR audit. Here's what you should retain for at least 10 years (the BIR's standard prescriptive period for tax assessments):

The TRAIN Law's Impact on Home Loan Deductions

Republic Act 10963, known as the TRAIN Law (Tax Reform for Acceleration and Inclusion), which took effect in January 2018, made significant changes. Most notably, it removed personal and additional exemptions (the old 50,000 basic personal exemption and 25,000 per dependent) and replaced them with higher income tax brackets that are more favorable for most earners.

For purely employed taxpayers, the removal of itemized deductions on personal income tax returns means home loan interest is no longer a path to tax savings. However, for self-employed individuals and mixed-income earners, the option to choose between OSD (40% of gross sales/receipts) and itemized deductions remains — and itemized deductions can still include qualifying home loan interest.

Real Example: Self-Employed Taxpayer Refinancing

Maria is a freelance graphic designer who owns a condominium unit in Quezon City. She uses one room as a dedicated home office — roughly 20% of the unit's floor area. She has a home loan with an outstanding balance of 2,500,000 currently at 8.5% per annum, which she refinances to 5.99% per annum through Nook.

Under the old loan, her annual interest payment was approximately 212,500. Under the new loan, it drops to approximately 149,750 — a saving of 62,750 per year before tax effects.

Because Maria is self-employed and uses 20% of her property for business, she may potentially argue that 20% of her home loan interest — about 29,950 annually — qualifies as a deductible business expense. She should consult a CPA to structure this properly and ensure she has documentation (floor plan, photos, business registration) supporting the business use claim.

To see how much Maria or someone in a similar situation could save just from the rate reduction alone, use the Nook home loan refinance calculator to run the numbers on your own loan.

VAT on Bank Services: What Refinancing Borrowers Should Know

Banks in the Philippines are VAT-exempt on their core lending and borrowing activities under Section 109 of the NIRC. This means the interest you pay on your home loan does not carry a 12% VAT. However, certain bank service fees — such as processing fees for loans — may be subject to VAT, which the bank should indicate on their invoices. If you're a VAT-registered business and you can demonstrate the loan is connected to your taxable business activity, you may be able to claim input VAT on these fees. Again, consult a CPA for your specific situation.

When to Consult a CPA Before Refinancing

Most homeowners won't need to engage an accountant just because they're refinancing. But you should seek professional advice if:

The Bigger Picture: Rate Savings vs. Tax Benefits

Here's the honest reality for most Filipino homeowners: the tax angle of refinancing is secondary. The primary financial win comes from securing a significantly lower interest rate.

If you're currently paying 8% or higher on your home loan, you could be overpaying by tens of thousands of pesos every year. Current home loan interest rates in the Philippines from major banks show that refinancing to rates as low as 5.99% p.a. is achievable through Nook — and for a 3,000,000 loan, that rate difference alone can save over 50,000 per year.

Tax deductions, where available, are a bonus — not the foundation of the refinancing case. Focus first on locking in the best possible rate, then work with a CPA to optimize your tax position based on your specific circumstances.
