In Philippine practice, the question “who pays the Documentary Stamp Tax” is often answered in two different ways, and they should not be confused.

The first is the statutory incidence of the tax: who is treated by tax law as the party on whom the Documentary Stamp Tax, or DST, is imposed with respect to a particular taxable instrument or transaction.

The second is the economic burden by agreement: which party, as between themselves, ultimately shoulders the cost under their contract.

These two are related, but they are not always the same. A loan agreement may state that the borrower must reimburse or shoulder DST, but that does not necessarily change the legal character of the tax under the National Internal Revenue Code and the liability rules applicable to the parties involved.

This article explains, in Philippine context, who pays DST on a loan, a real estate mortgage or chattel mortgage given as security, and a promissory note, how the rules interact, and the practical drafting and compliance issues that matter.

1. What is Documentary Stamp Tax?

Documentary Stamp Tax is an excise tax on documents, instruments, loan agreements, and papers evidencing the acceptance, assignment, sale, or transfer of an obligation, right, or property incident thereto. It is not a tax on property itself, nor purely a tax on income. It is imposed because a document or instrument of a specified class exists or because a taxable transaction is evidenced by such document.

In lending transactions, DST may arise because the parties execute one or more of the following:

a loan agreement or similar evidence of indebtedness,
a promissory note,
a mortgage agreement securing the debt.

A single financing deal may therefore generate DST issues at more than one level. The key is to determine which instrument is taxable, whether the tax has already attached to the principal obligation, and whether a related security instrument gives rise to a separate DST.

2. General principle: the law may impose the tax, but the parties may reallocate the cost

Under Philippine tax law, the person or persons primarily liable to the government for DST are determined by the tax statute and implementing rules. However, as between lender and borrower, the parties may agree who will actually bear the cost.

So when asking “who pays,” there are really three different questions:

Who is the taxpayer or statutory obligor?
Who remits the tax to the BIR in practice?
Who bears the cost under the contract?

In actual lending practice:

the lender often computes and remits DST because it is the party maintaining the loan records and handling tax compliance,
the borrower is often contractually required to shoulder or reimburse all taxes and charges connected with the loan documents, including DST,
but the answer still depends on the specific taxable instrument involved.

3. DST on a loan: who pays?

A. As a matter of tax law

A loan evidenced by a taxable instrument is generally subject to DST under the provisions of the Tax Code governing debt instruments or loan agreements. In substance, the tax attaches to the instrument evidencing the indebtedness.

In practice, the lender or creditor is commonly the party that handles the DST compliance because:

it prepares or controls the lending documentation,
it is the party most directly engaged in the lending business,
it is usually in the best position to compute the DST base and ensure timely filing and payment.

But the tax burden may be passed on contractually.

B. As a matter of contract

In most Philippine loan documents, especially bank and commercial credit documents, the loan agreement contains a clause saying that the borrower shall pay, reimburse, or hold the lender free from all taxes, fees, charges, and expenses arising from the execution, perfection, and enforcement of the loan and security documents, except taxes on the lender’s net income.

Because of this, while the lender may be the one that pays the BIR, the borrower usually shoulders DST economically.

C. Bottom line for loans

For a standard loan transaction:

The lender commonly remits the DST, but
the borrower commonly bears it by agreement.

If there is no contractual allocation, disputes may arise, and one must return to the tax law and the exact nature of the instrument executed.

4. DST on a promissory note: who pays?

A promissory note is a classic example of a debt instrument. It is a written unconditional promise to pay a sum certain in money, either on demand or at a fixed or determinable future time.

A. Why a promissory note matters for DST

A promissory note is often the very document that evidences the indebtedness. Because DST is imposed on specified debt instruments, a promissory note may itself be the taxable basis.

B. Who is primarily associated with the tax?

A promissory note is executed by the maker, who is usually the borrower. From a practical and legal standpoint, the note is the borrower’s written promise to pay.

That is why many lawyers and accountants will say, in simple terms, that the borrower pays the DST on the promissory note, because the borrower is the one issuing the note and is the one obtaining the loan proceeds.

However, in commercial practice, especially where a financial institution is involved, the lender frequently calculates and pays the DST to the BIR and then charges it back to the borrower under the facility documents.

C. Important anti-duplication issue

A critical issue is whether the loan agreement and the promissory note executed for the same indebtedness both attract separate DST.

The usual rule in tax analysis is that one must avoid double taxation of the same taxable incident where the law and regulations indicate that the principal evidence of debt has already been subjected to DST. If the note merely evidences the same indebtedness already taxed under the principal debt instrument, one must carefully determine whether separate DST is still due or whether only one taxable debt instrument should be recognized for that obligation.

This becomes highly document-specific. The decisive question is whether there are separate taxable instruments representing distinct taxable incidents, or whether one document merely implements the same indebtedness already evidenced and taxed elsewhere.

D. Bottom line for promissory notes

In ordinary lending usage:

the borrower, as maker of the note, is commonly treated as the one economically bearing DST, while
the lender often handles remittance and documentary compliance.

If the promissory note is the principal evidence of debt, it is usually the focal DST instrument for the loan.

5. DST on a mortgage agreement: who pays?

A mortgage is generally a security arrangement, not the principal debt itself. There are two common forms:

Real Estate Mortgage (REM), covering immovable property;
Chattel Mortgage, covering movable property.

A. The mortgage is separate from the loan

A mortgage secures the performance of the borrower’s obligation. It is accessory to the principal obligation, but it can still be a separately taxable document if the Tax Code imposes DST on mortgages, pledges, and deeds of trust.

So even if DST has already been paid on the loan or promissory note, there may also be DST on the mortgage instrument itself, because the law taxes certain security instruments separately.

B. Who usually pays it?

In practical Philippine transactions, the mortgagor usually shoulders the DST on the mortgage. Since the mortgagor is ordinarily the borrower or the property owner giving the collateral, the borrower usually bears this cost.

Even when the mortgagee is the lender, the mortgage is being constituted over the borrower’s or third party’s property to secure the borrower’s obligation, so the loan documents almost always require the borrower to pay all charges for registration, notarization, annotation, and DST on the mortgage.

C. Special case: third-party mortgage

Sometimes a third party gives a mortgage to secure someone else’s debt. In that case:

the third party is the mortgagor,
the borrower remains the principal debtor,
and the contract may specify whether the borrower reimburses the third-party mortgagor for DST and related expenses.

As to the government, the taxable instrument is still the mortgage. As between the private parties, reimbursement and cost allocation depend on the contract.

D. Bottom line for mortgages

For mortgage DST, the borrower or mortgagor usually pays in substance and by contractual allocation. In institutional lending, the lender often arranges compliance, but the cost is commonly charged to the borrower.

6. The clean practical answer: in Philippine lending, the borrower usually shoulders DST

If the question is asked in the ordinary commercial sense, the most practical answer is this:

In Philippine loan transactions, the borrower usually shoulders the Documentary Stamp Tax on the loan documents, promissory note, and mortgage, because the loan documents almost always require the borrower to bear all taxes and expenses related to the credit facility and its security.

That said, this should not be oversimplified.

A better legal answer is:

DST liability depends on the specific taxable instrument;
the lender often pays and remits it in practice;
the borrower usually bears the cost under the contract.

7. Why confusion happens

Confusion comes from several sources.

A. People mix up “liable to the BIR” with “who shoulders it”

The party who actually files and pays is not always the party who ultimately bears the cost.

B. Multiple documents exist in one financing deal

A transaction may include:

a principal loan agreement,
one or more promissory notes,
a mortgage,
amendments, renewals, or restructuring documents.

Each may have different DST consequences.

C. Lawyers and accountants often speak from different vantage points

A tax lawyer may focus on the statutory taxable instrument.
A bank lawyer may focus on the loan covenant that the borrower pays all taxes and expenses.
An accountant may focus on which side books the tax as an expense or advances it first.

All three may sound different while describing the same transaction.

8. Can the parties agree that the lender pays DST?

Yes. As between themselves, the parties may stipulate that the lender absorbs the DST. This is a matter of private agreement, subject to ordinary contractual freedom.

For example:

a lender trying to attract borrowers may advertise “zero DST charges” and absorb the cost;
affiliated parties in an intra-corporate loan may allocate the cost to the lender for convenience;
a seller-financing arrangement may roll the tax into the financed amount.

But that private arrangement does not erase the tax. It only changes which party bears the burden between themselves.

9. Can the borrower be made to reimburse DST even if the lender initially paid it?

Yes. This is standard practice.

A typical loan clause will provide that the borrower shall pay or reimburse:

DST,
registration fees,
notarial fees,
annotation fees,
sheriff’s fees or legal costs in case of enforcement,
all other charges relating to the documentation, perfection, protection, and enforcement of the lender’s rights.

So the lender may initially pay DST and then:

deduct it from the loan proceeds,
bill it separately,
capitalize it into the borrower’s obligations where permitted by the contract.

10. What if the documents are silent?

If the documents do not say who shoulders DST, the issue becomes more technical.

One must then examine:

the exact taxable instrument,
which party executed it,
which party’s act or transaction caused the tax to arise,
the specific Tax Code provision governing that instrument,
the implementing regulations and revenue issuances applicable to the document.

In a dispute between lender and borrower, the court will likely construe the contract as written and then determine the statutory tax consequences. In practice, however, well-drafted credit documents almost never leave this point unaddressed.

11. What about renewals, extensions, and restructuring?

This is one of the most important practical areas.

DST may arise again if there is a renewal, extension, or restructuring that produces a new taxable instrument or materially modifies the debt evidenced by the original one.

Examples that may trigger further DST analysis:

execution of a new promissory note,
increase in principal amount,
extension of maturity under a new instrument,
replacement of one note with another,
amendment and restatement of a loan agreement,
additional mortgage or increased secured amount.

The mere label “amendment” does not control. What matters is whether there is a new or renewed taxable debt instrument or security instrument.

In these situations, the borrower is still usually the party that shoulders the DST by contract.

12. What about revolving credit lines and multiple availments?

Credit facilities can be structured in different ways:

a single term loan,
a revolving line,
multiple drawdowns evidenced by separate promissory notes,
omnibus security arrangements.

DST analysis can differ depending on whether:

there is one principal taxable debt instrument for the facility,
each drawdown is evidenced by a separate taxable note,
each renewal or rollover creates a new taxable event.

In many bank facilities, each availment may be evidenced by a separate promissory note, and that note may carry its own DST consequence depending on the structure and prevailing tax treatment.

Again, as a practical matter, the borrower usually pays.

13. Mortgage DST is separate from registration fees and annotation fees

Another common misconception is that DST on a mortgage is the same as:

Registry of Deeds fees,
transfer or annotation fees,
notarial fees,
filing fees for chattel mortgage registration.

They are not the same.

A borrower who grants a mortgage may have to pay all of the following separately:

DST on the mortgage instrument,
notarial fees,
registration or annotation fees,
and other incidental charges.

Thus, even if the lender says “borrower pays the mortgage costs,” those costs may include much more than DST.

14. What if the lender is exempt or the transaction is exempt?

Some entities or transactions may enjoy statutory exemptions from DST, whether by special law, treaty, charter, or specific tax provision. If a valid exemption applies, then the question of “who pays” may become moot because no DST is due.

But exemptions are construed strictly against the taxpayer and must be clearly grounded in law. One should not assume exemption merely because:

the lender is a government-related entity,
the borrower is a corporation registered with an investment promotion agency,
the transaction is internal or related-party,
the loan is for a special purpose.

The precise legal basis of exemption must be identified.

15. Consequences of non-payment of DST

DST compliance is not a minor housekeeping issue. Non-payment can have serious consequences.

Possible consequences include:

deficiency DST assessments,
surcharges, interest, and compromise penalties,
issues in enforcement or evidentiary use of the document,
delays in registration or annotation where proof of tax compliance is required,
disputes between borrower and lender over reimbursement obligations.

A lender will therefore usually make sure DST is paid before or at the time of release, and then recover it from the borrower if the contract so provides.

16. How loan documents usually allocate DST in the Philippines

A typical allocation clause in Philippine finance documents does one or more of the following:

states that the borrower shall shoulder all DST and other taxes, fees, and expenses in connection with the execution and implementation of the loan and security documents;
allows the lender to debit or deduct such amounts from the loan proceeds;
requires the borrower to reimburse the lender on demand if the lender advances the payment;
excludes only taxes on the lender’s net income, franchise taxes, or similar taxes properly imposed on the lender itself.

This is why practitioners often answer, in ordinary business terms, that the borrower pays DST.

17. If there is both a loan agreement and a promissory note, which one governs the payment clause?

Usually, the loan agreement governs overall allocation of taxes and expenses, while the promissory note serves as evidence of the particular availment or indebtedness.

So even if the promissory note does not expressly say who shoulders DST, the broader credit agreement may already provide that the borrower bears all documentary taxes and related charges.

In case of conflict:

check the hierarchy clause, if any;
check which document specifically addresses taxes;
check cross-default, incorporation, and entire agreement clauses;
apply basic rules of contract interpretation.

18. In consumer loans versus commercial loans

Consumer or retail loans

Banks and financing companies often incorporate DST into:

processing charges,
amount financed,
deductions from proceeds,
amortization disclosure.

The borrower still typically bears it, though sometimes the lender markets the product as absorbing certain fees.

Commercial and corporate loans

DST is usually separately identified in the term sheet, closing memorandum, or disbursement computation. The borrower almost always shoulders it unless the lender expressly waives or absorbs it.

19. In intercompany loans and shareholder advances

Related parties often neglect DST because they assume internal transactions are informal. That is risky.

If there is a promissory note, loan agreement, or other debt instrument evidencing the obligation, DST issues can still arise even for related-party loans. The parties may agree that either side will shoulder it, but absent clear documentation, tax exposure remains.

A common mistake is documenting advances only after the fact, then overlooking the DST impact of the instrument eventually executed.

20. Does notarization determine DST liability?

No. Notarization does not by itself determine whether DST is due. DST depends on whether the document is of a class taxed by law.

However, notarization often matters in practice because:

mortgages are typically notarized before registration,
lenders often complete DST payment together with closing formalities,
notarized documents are more likely to be formally reviewed for tax and registration compliance.

So notarization is related administratively, but it is not the legal source of the DST.

21. The most accurate concise answers

If asked in different settings, the answers can be framed as follows:

Business answer

The borrower usually pays.

Banking practice answer

The lender often remits it, but charges it to the borrower.

Technical legal answer

DST is imposed according to the taxable instrument involved; contractual allocation may shift the economic burden to the borrower without changing the existence of the tax.

Mortgage-specific answer

DST on the mortgage is usually borne by the mortgagor or borrower, unless the parties agree otherwise.

Promissory note answer

DST on the promissory note is commonly borne by the borrower as maker, though the lender often handles payment and collection.

22. Sample practical formulations

These are the kinds of practical conclusions lawyers usually give:

On the loan itself: the borrower generally shoulders DST, especially where the loan agreement says all taxes and expenses for the facility are for the borrower’s account.
On the promissory note: the borrower, as maker and debtor, commonly bears the tax, though the lender may pay first and recover it.
On the mortgage: the mortgagor or borrower typically shoulders DST and all registration-related expenses.
As to the BIR: the party in control of the documentation, often the lender, usually ensures payment and compliance.

23. Drafting guidance for Philippine practitioners

A well-drafted loan package should clearly state:

that the borrower shoulders all DST on the loan and security documents;
that the lender may advance payment and recover it from the borrower;
that the lender may deduct it from the proceeds;
that the borrower must cooperate in executing any tax filings and supporting documents;
that additional DST due to amendments, renewals, or increases in exposure will also be for the borrower’s account.

For mortgages, it should also say that the borrower shoulders:

notarization,
registration,
annotation,
cancellation and release expenses where applicable.

This avoids later arguments.

24. Final conclusion

In the Philippines, the safest and most practical legal answer is this:

Documentary Stamp Tax on a loan, mortgage agreement, and promissory note is usually borne by the borrower as a matter of contractual allocation, even though the lender often computes, remits, or initially advances the tax as part of documentation and closing.

More precisely:

Loan / debt instrument: usually charged to the borrower, often remitted by the lender.
Promissory note: usually borne by the borrower as maker of the note, though lender-side compliance is common.
Mortgage agreement: usually borne by the borrower or mortgagor, together with other perfection and registration costs.

The fully correct legal analysis always depends on:

the exact instrument executed,
whether multiple documents evidence the same indebtedness,
whether the mortgage is separate and independently taxable,
whether an exemption applies,
and what the parties agreed in their contract.

Where the documents are silent, the issue becomes technical and turns on the tax statute and the nature of the instrument. But in actual Philippine lending practice, the borrower almost always ends up paying the DST.

If you want, I can turn this into a more formal law-journal style article with headings, footnote-style formatting, and a stronger bar-exam or practitioner tone.
