Quick answer

Documentary stamp tax (DST) does not depend on the document’s title alone. What matters is what the deed actually transfers and the payment status of the condominium:

If the registered owner assigns or sells ownership of the condominium unit, the transfer is generally subject to DST under Section 196 of the Tax Code.
If a buyer has fully paid the developer but assigns the unit before the Deed of Absolute Sale is issued, BIR rules treat the assignment for consideration as a separate sale of real property, subject to DST.
If the unit is still unpaid or partially paid under a Contract to Sell and the buyer transfers only contractual rights and obligations, the BIR has ruled in fact-specific cases that Section 196 DST does not apply because the condominium itself has not yet been sold by the assignor. A ₱30 DST on the notarial certificate may still apply.
A later Deed of Absolute Sale from the developer to the assignee normally has its own DST consequences.

When Section 196 applies, the rate is ₱15 for every ₱1,000, or fraction of ₱1,000, of the higher of the consideration and the property’s fair market value. The DST return and payment are generally due within five days after the close of the month in which the taxable deed was made, signed, issued, accepted, or transferred.

Because a small difference in the deed, payment history, or developer’s documents can change the result, do not assume that an assignment is exempt—or taxable—solely because it is called a “Deed of Assignment.”

First determine what is being assigned

Philippine law treats a condominium as an interest in real property consisting of ownership or another recognized interest in the unit, together with an interest in the land and common areas. This is why a transfer of an owned condominium ordinarily falls under the real-property DST rules. See Section 2 of the Condominium Act.

The following situations must be distinguished.

The assignor already owns the unit

If a Condominium Certificate of Title (CCT) is registered in the assignor’s name and the deed conveys that unit to the assignee for consideration, the transaction is ordinarily a sale or other onerous conveyance of real property. Section 196 DST applies even if the document is labeled “Deed of Assignment” instead of “Deed of Absolute Sale.”

The same analysis generally applies when the deed transfers a separately titled parking slot or other separate real-property interest. Each CCT, property description, and declared consideration should be checked.

The assignor has fully paid, but the developer has not issued the final deed

Revenue Regulations No. 17-2003 provide that when the purchase price has been fully paid but, before the final deed of sale, the buyer assigns the property to another person for consideration, the assignment is treated as a separate sale of real property. DST is based on the higher of:

the consideration stated in the Deed of Assignment; or
the property’s fair market value at the time of assignment.

The eventual Deed of Absolute Sale from the developer may also carry DST. Thus, a fully paid pre-selling assignment can involve two distinct transactions rather than one.

The assignor has not fully paid under a Contract to Sell

This is materially different. The assignor may be transferring only the right to complete the purchase, together with the obligation to pay the remaining balance—not legal ownership of the condominium.

In BIR Ruling No. OT-029-2024, the BIR ruled, on the represented facts, that an assignment of rights, interests, and obligations under an incompletely paid Contract to Sell was not a sale of the real property itself and therefore was not subject to Section 196 DST. The ruling nevertheless imposed the ₱30 DST applicable to the notarial acknowledgment under Section 188.

That ruling is useful but not a blanket exemption. It expressly depended on facts including the incomplete payment, the nature of the rights transferred, and the amount paid by the assignee. A different result may follow if:

the developer’s price was already fully paid;
the deed purports to convey the unit itself;
possession, beneficial ownership, or other property rights had already passed;
the assignee paid an assignment premium;
the parties’ records contradict the wording of the deed; or
the arrangement is effectively a sale despite its label.

An assignment premium or gain may also produce capital-gains, withholding-tax, VAT, or income-tax consequences even when Section 196 DST does not apply.

The transfer is gratuitous

Section 196 now expressly includes donations of real property. If the deed actually transfers ownership of the condominium without consideration, DST is generally computed from the applicable fair market value.

A gratuitous assignment of only contractual rights under an unpaid Contract to Sell requires a separate analysis. Do not automatically apply either the real-property sale rule or the donation rule without reviewing the original contract, payment history, and developer’s approval.

How much DST is payable?

Section 196, as amended by the TRAIN Law, imposes:

₱15 for every ₱1,000, or fractional part of ₱1,000, of the applicable tax base.

The practical formula is:

DST = ₱15 × round up (tax base ÷ ₱1,000)

For transfers between private parties, the tax base is generally the higher of:

the consideration contracted to be paid; or
the fair market value determined under Section 6(E) of the Tax Code.

Fair market value generally requires comparing the BIR zonal value and the value appearing in the applicable local assessor’s schedule, subject to the BIR’s valuation rules. For a condominium, the unit, parking slot, improvements, area, classification, and effective dates of the valuation schedules must be checked.

Example

Assume the deed states an assignment price of ₱6,000,000, while the applicable fair market value is ₱6,250,400.

The higher amount is ₱6,250,400:

₱6,250,400 ÷ ₱1,000 = 6,250.4

Round that up to 6,251:

6,251 × ₱15 = ₱93,765 DST

Simply multiplying by 1.5% would understate the tax whenever the base is not an exact multiple of ₱1,000.

When one contracting party is the Government, Section 196 uses actual consideration. Claims involving encumbrances, assumed balances, exemptions, or special transactions should be submitted to the BIR for a written computation rather than deducted informally.

When is the deadline?

The return and tax are generally due within five days after the close of the month in which the taxable document was made, signed, issued, accepted, or transferred.

For example:

Deed signed on January 3: deadline is February 5.
Deed signed on January 31: deadline is also February 5.

The five days are counted after month-end, not from the individual signing date. If the deadline falls on a weekend, holiday, or declared non-working day, BIR tax calendars generally move it to the next working day.

The current five-day rule is confirmed by BIR Revenue Memorandum Circular No. 67-2024. Do not rely on older materials stating a ten-day deadline.

Waiting for the developer’s approval, release of the CCT, full payment of the assignee’s price, or registration with the Registry of Deeds normally does not postpone DST that has already accrued upon execution of a taxable deed.

Who must pay?

The deed commonly assigns the cost to the buyer or assignee, but that private agreement does not by itself determine the Government’s collection rights.

Under the Tax Code, DST is imposed on persons making, signing, issuing, accepting, or transferring the taxable document or transaction. If one party is legally exempt, the non-exempt party is directly liable. Both sides should therefore confirm that the correct return was filed and the tax was paid, regardless of who agreed to shoulder the cost.

How to file and pay

1. Review the complete transaction before signing

Gather and compare:

the reservation agreement, Contract to Sell, and amendments;
the developer’s statement of account and payment schedule;
official receipts or invoices for all payments;
the proposed Deed of Assignment;
the developer’s written consent or assignment approval;
the CCT and tax declaration, if already issued;
documents for any separately sold parking slot;
the assignment price, assumed balance, and other consideration; and
the seller’s classification of the property as a capital or ordinary asset.

The deed should clearly state whether the assignor is transferring ownership or only rights and obligations under the Contract to Sell.

2. Establish the correct value and execution date

Secure the relevant tax declarations and check the BIR zonal value effective on the controlling transaction date. Confirm the actual date of signing and notarization. Do not antedate the deed.

If the unit and parking slot have separate titles or valuations, identify each separately rather than using an unsupported lump-sum allocation.

3. Apply for an ONETT computation

Transfers of real property are processed as one-time transactions. The BIR’s eONETT system allows taxpayers to submit an application and upload supporting documents. Depending on the seller’s asset classification, the application may involve capital gains tax and DST or expanded withholding tax and DST.

The application is routed to the concerned Revenue District Office for review and issuance of an ONETT Computation Sheet. The current BIR checklist under RMO No. 17-2026, Annex D generally calls for the parties’ TINs, notarized transfer document, certified tax declarations, certified CCTs, and applicable authority documents such as a Special Power of Attorney or corporate board authorization. Additional documents may be required for installment sales, foreign execution, corporations, exemptions, or antedated instruments.

For a transfer of incompletely paid contractual rights, ask the RDO to confirm in writing whether Section 196 applies. Present the entire Contract to Sell and payment record; submitting only the assignment deed can produce the wrong classification.

4. File BIR Form No. 2000-OT and pay on time

Use BIR Form No. 2000-OT for DST on a one-time real-property transaction.

For an eONETT application, the system generates the applicable return after approval of the computation. Payment may be made through the payment channels shown by the BIR system, including authorized banks, Revenue Collection Officers subject to applicable payment rules, or available electronic channels. Upload clear proof of payment afterward.

Start the process early. If the statutory deadline is approaching while the computation remains pending, immediately contact the concerned RDO. A pending eONETT application should not be assumed to extend the deadline.

5. Obtain the eCAR when registration is required

After the BIR verifies the return and payment, submit or present the required originals and claim the Electronic Certificate Authorizing Registration (eCAR). The Registry of Deeds generally requires the appropriate eCAR before registering a transfer and issuing a new CCT.

DST payment is not the entire transfer process. Capital gains tax, expanded withholding tax, donor’s tax, VAT, local transfer tax, registration fees, and developer charges may apply separately, each under its own rules and deadlines.

Evidence to preserve

Keep both electronic and physical copies of:

the signed and notarized deed and all drafts showing the agreed terms;
the original Contract to Sell and amendments;
the developer’s statement of account before and after assignment;
proof of every payment by the assignor and assignee;
proof of any assignment premium or reimbursement;
the developer’s consent, approval, or acknowledgment;
certified CCTs and tax declarations;
the zonal-value schedule used;
filed tax returns and payment confirmations;
the ONETT Computation Sheet;
eONETT transaction numbers, notices, and claim slips;
the eCAR and Registry of Deeds receipts; and
correspondence with the developer, bank, broker, accountant, lawyer, or BIR.

These records are particularly important when the parties claim that the deed transferred only contractual rights rather than ownership.

Common mistakes

Assuming every Deed of Assignment is automatically subject to 1.5% DST.
Assuming every pre-selling assignment is exempt even though the developer was already fully paid.
Looking only at the document’s title instead of its operative provisions.
Using the lowest of the contract price, zonal value, and assessor’s value.
Forgetting to round every fraction of ₱1,000 upward.
Excluding a parking slot or other separately transferred interest.
Treating the developer’s assignment or processing fee as payment of BIR DST.
Waiting for title registration before addressing the five-day deadline.
Assuming a capital-gains-tax exemption for a principal residence automatically exempts DST.
Declaring an assignment “without consideration” despite reimbursements, assumed obligations, side payments, or debt cancellation.
Filing and paying without keeping a validated return or electronic confirmation.
Cancelling or rescinding a deed without documenting the rescission and addressing any tax already accrued.

When professional help is urgent

Consult a Philippine tax lawyer or experienced tax practitioner promptly if:

the deed has already been signed and the DST deadline is near or has passed;
the parties disagree over whether the developer was fully paid;
the assignment price includes reimbursements, assumed debt, or side payments;
the deed transfers both a unit and parking slot but gives only one price;
the developer’s records and the deed describe different transactions;
a party is a corporation, foreign national, estate, trust, or tax-exempt entity;
the transaction is a donation, tax-free exchange, merger, foreclosure, dacion en pago, or court-ordered transfer;
the BIR and developer give conflicting classifications;
the deed was signed abroad, antedated, rescinded, or replaced; or
an eCAR or registration has been rejected.

Where the classification remains genuinely uncertain, a written BIR ruling or documented RDO position is safer than relying on an oral answer.

FAQ

Is every condominium Deed of Assignment subject to 1.5% DST?

No. Section 196 generally applies when the deed transfers the condominium itself or when a fully paid buyer assigns the property for consideration before the final deed. An assignment of only incompletely paid Contract-to-Sell rights may fall outside Section 196, depending on the complete facts.

What if the unit is only partially paid?

A fact-specific BIR ruling has treated an assignment of incompletely paid contractual rights as not subject to Section 196 DST. The assignment can still have income-tax or withholding-tax consequences, and a ₱30 notarial-certificate DST may apply. Obtain RDO confirmation before treating the transaction as exempt.

What if the developer has already been paid in full?

An assignment for consideration before the final deed is generally treated as a separate real-property sale under BIR regulations and is subject to DST based on the higher of the assignment consideration and fair market value.

Is DST due only after the CCT is transferred?

No. For a taxable assignment, DST generally accrues from the taxable document or transaction. Registration and issuance of the new CCT occur later.

Does a “no consideration” clause eliminate DST?

Not necessarily. If ownership is donated, Section 196 generally imposes DST using fair market value. The BIR may also examine reimbursements, debt assumptions, side payments, and the actual substance of the arrangement.

Is the developer’s assignment fee the same as DST?

No. A developer’s administrative or transfer fee is a private contractual charge. It does not replace BIR tax filing or payment.

Does the principal-residence capital-gains exemption also exempt DST?

No automatic DST exemption follows from the capital-gains-tax exemption. Each tax has its own legal basis and requirements.

What happens if DST is paid late?

Late filing or payment can result in surcharge, interest, and applicable compromise penalties. The ordinary civil surcharge is generally 25%, while taxpayers classified by the BIR as micro or small may qualify for the reduced 10% civil penalty and reduced interest under the Ease of Paying Taxes rules. The exact amount depends on taxpayer classification, delay, and circumstances. Ask the RDO to compute it and file and pay promptly rather than waiting for a demand.

Does unpaid DST invalidate the deed?

Nonpayment does not by itself settle whether the underlying agreement is valid. However, Section 201 of the Tax Code prevents a taxable unstamped document from being recorded or used in court until the required tax is paid, and a notary may not acknowledge a taxable document without the proper stamp.
