After identifying transactions that may trigger Documentary Stamp Tax (DST), the next critical step is understanding how DST is computed and which party is legally liable to pay it. In practice, many taxpayers recognize that a transaction is subject to DST but still incur deficiencies due to incorrect tax base selection, misapplication of rates, failure to identify the proper taxpayer, or mistaken reliance on contractual shifting clauses.
Because DST is imposed on specific instruments and privileges under the National Internal Revenue Code of 1997 (NIRC), the method of computation depends on the nature of the document executed, while liability depends on the specific provision of law governing the transaction.
Legal Basis for Computation and Liability
DST is imposed under Title VII, Sections 173 to 198[1] of the NIRC, as amended. Each section provides a specific taxable document, corresponding rate, and in many cases the person primarily liable for the tax.
Unlike income tax, DST is not computed on profit. It is generally based on one of the following:
- Par value of shares issued
- Actual consideration paid
- Face value or principal amount of indebtedness
- Fair market value or consideration for transferred property
- Amount of rental or premium stated in the contract
- Fixed statutory amount per instrument
Accordingly, accurate DST compliance begins with identifying the correct taxable base, not merely the transaction value recorded in accounting books.
General Rule on the Person Liable
As a rule, the person making, signing, issuing, accepting, or transferring the taxable document may be held liable for DST under Section 173 of the NIRC, as amended.
In practical terms:
- The issuer usually bears DST on original issue of shares;
- The borrower or lender may bear DST on debt instruments depending on arrangement and documentation;
- The seller, buyer, or both parties may become liable depending on the instrument involved;
- In many transactions, the BIR may assess any party participating in the taxable instrument if the tax remains unpaid.
Even if parties contractually agree that one side will shoulder DST, such private agreement does not bind the government. The BIR may still assess the legally liable party under the NIRC.
Common Corporate Transactions: Computation and Liability
1. Original Issue of Shares of Stock
Under Section 174 of the NIRC, as amended, DST applies to the original issuance of shares.
Tax Base
- Par value shares – based on par value of shares issued
- No-par shares – based on actual consideration received
DST Rate
0.75% of the par value of the shares issued, or 0.75% of the actual consideration received for no-par value shares.
Who Pays
The issuing corporation is generally responsible for remitting DST because the tax is imposed on the privilege of issuing shares.
Common Errors
- Computing DST based on the subscription price instead of the par value of shares issued
- Confusing subscribed shares with issued shares for DST purposes
- Late payment, after SEC approval instead of upon issuance
2. Sale or Transfer of Shares
Under Section 175, DST applies to the sale, agreement to sell, transfer, or memorandum of transfer of shares.
Tax Base
Generally based on the par value or as prescribed by applicable rules.
DST Rate
₱1.50 for every ₱200.00, or fractional part thereof, of the par value of the shares transferred.
Who Pays
Liability may fall upon the seller, transferor, broker, or party effecting the transfer, depending on circumstances and documentation.
Common Errors
- Assuming no DST applies because the transaction is exempt from capital gains tax
- Assuming that intra-group transfers are exempt from DST merely because they occur between related parties or entities within the same corporate group
- Treating tax-free exchange as automatically exempt from DST
3. Loans, Advances, and Debt Instruments
Under Section 179, DST applies to debt instruments, including promissory notes, loan agreements, credit facilities, and instruments evidencing indebtedness.
Tax Base
Based on the issue price or principal amount of the debt instrument.
DST Rate
₱1.50 for every ₱200, or fractional part thereof, of the issue price of the debt instrument.
Who Pays
Usually borne by the borrower, though lenders often collect and remit under contractual arrangements.
Common Errors
- Ignoring shareholder advances which are those in the nature of loans
- Failure to stamp intercompany loans
- Non-payment on renewals or restructured loans
- Understating principal amount
4. Real Property Sales and Conveyances
Under Section 196, DST applies to deeds of sale, conveyances, and transfers of real property.
Tax Base
Computed on the higher of:
- Contract price; or
- Fair market value / zonal value where applicable.
DST Rate
₱15.00 for every ₱1,000, or fractional part thereof, based on the taxable consideration.
Who Pays
Commonly shifted by contract to the buyer, but legal liability depends on the taxable instrument and governing rules.
Common Errors
- Using undervalued consideration
- Ignoring assumed mortgage as part of consideration
- Treating related-party transfers as exempt without basis
5. Lease Agreements
Under Section 194, DST applies to lease agreements.
Tax Base
Based on the rental amount or consideration stated in the lease contract.
DST Rate
₱6.00 for the first ₱2,000, plus ₱2.00 for every additional ₱1,000 or fractional part thereof in annual rental.
Who Pays
Often contractually passed to the lessee, though parties may allocate by agreement.
Common Errors
- Failure to pay DST on lease amendments
- Ignoring extension agreements
- Recomputing only on monthly rent changes without reviewing full term
6. Mortgages and Security Instruments
Under Section 195, DST applies to mortgages, pledges, deeds of trust, and similar security instruments.
Separate DST may apply to:
- Real estate mortgages
- Chattel mortgages
- Pledges
- Deeds of assignment as collateral
Tax Base
Usually based on the amount secured.
DST Rate
- ₱40.00 on the first ₱5,000 of the amount secured; and
- An additional ₱20.00 for every additional ₱5,000, or fractional part thereof.
Who Pays
Typically the borrower or mortgagor, subject to contractual allocation.
Common Errors
- Paying DST on loan agreement only
- Forgetting separate DST on collateral documents
- Refiling deficiencies after increase in secured amount
Filing and Payment of DST
Under Section 200 of the NIRC of 1997[2], DST returns must generally be filed and the corresponding tax paid within five (5) days after the close of the month in which the taxable document was made, signed, issued, accepted, or transferred.
Importantly, the deadline is generally reckoned from the execution or issuance of the taxable instrument.
Failure to timely file and pay DST may result in the imposition of surcharges, interest, and compromise penalties under the Tax Code.
Conclusion
Identifying transactions subject to DST is only the first step. The next, and often more costly, issue is whether the tax was correctly computed and paid by the proper party.
Because DST rules vary depending on the instrument involved, taxpayers must evaluate each transaction individually under the NIRC of 1997. A disciplined review of rates, tax bases, and legal liability can prevent significant assessments and transform DST compliance from a recurring risk into a controlled process.
