The most common source of seller shock in Philippine property transactions is the gap between the agreed selling price and the amount the seller actually receives. Most sellers set their asking price with a net figure in mind — what they need to walk away with after the sale. What they frequently discover, at or after signing, is that the deductions between gross sale price and net proceeds are substantially larger than they anticipated. Sellers who underestimate the tax burden by 30 to 50 percent are not unusual. They are the norm.

This article builds the net proceeds calculation from the ground up — identifying every deduction that comes out of the gross sale price, explaining what each is, and showing how the sequence of deductions works. The figures used are illustrative, drawn from typical Metro Manila conditions for a resale unit at PHP 3,000,000. Apply the same framework to your specific transaction, using your actual figures, before agreeing to a sale price.

Net proceeds are what remains after all seller-side obligations have been paid from the gross sale price. The seller-side obligations in a Philippine property transaction fall into four categories: taxes, outstanding property obligations, broker commission, and any outstanding mortgage or liens. Each must be settled before the seller retains the balance.

The order matters because some obligations are fixed in amount regardless of the selling price, and some are computed as a percentage of the selling price or the BIR zonal value — whichever is higher. A seller who negotiates a price reduction to close a deal may not reduce their tax obligations proportionally, which compresses the net proceeds more sharply than the price reduction alone would suggest.

Deduction 1: Capital Gains Tax (CGT)

Capital Gains Tax is the largest seller-side deduction in most Philippine property transactions. It is computed at six percent of the higher of the actual selling price or the BIR zonal value for the property’s location — not on the profit from the sale, and not solely on the agreed price if the zonal value is higher.

On a PHP 3,000,000 sale where the BIR zonal value is PHP 2,800,000, CGT is computed on PHP 3,000,000 — the higher figure. At six percent, that is PHP 180,000. On a PHP 3,000,000 sale where the BIR zonal value is PHP 3,200,000, CGT is computed on PHP 3,200,000. At six percent, that is PHP 192,000 — despite the agreed selling price being lower than the tax base. This is the zonal value trap that catches sellers who price below or close to zonal value.

CGT is technically the seller’s obligation. In practice, some sellers negotiate for the buyer to absorb CGT as a condition of the sale — but this is a convention, not a rule, and it reduces the buyer’s effective price. A seller who negotiates “buyer pays CGT” is effectively discounting the net price to the buyer by the CGT amount, whether or not the headline selling price reflects this.

Deduction 2: Documentary Stamp Tax (DST)

Documentary Stamp Tax is levied on the Deed of Sale at a rate that should be confirmed with the BIR, as it is subject to change. As a planning figure based on prevailing rates, DST is approximately 1.5 percent of the higher of selling price or zonal value. On PHP 3,000,000, DST is approximately PHP 45,000 to PHP 52,500.

DST is conventionally paid by the buyer, but — like CGT — this allocation is negotiable. In some transactions, particularly where the seller is motivated to close and the buyer has leverage, DST ends up being absorbed partially or wholly by the seller as a concession. Whatever the agreed allocation, DST must be paid before the Registry of Deeds will process the title transfer.

Deduction 3: Real Property Tax Arrears

Any unpaid Real Property Tax (RPT) on the unit must be cleared before the sale can proceed. RPT arrears are the seller’s obligation to resolve. They are not optional and cannot be transferred to the buyer as a post-closing obligation — a buyer conducting proper due diligence will verify RPT clearance before closing, and any arrears must be cleared at or before that point.

For a unit with current RPT payments, this deduction is zero. For a unit where RPT has been allowed to accumulate — which is common in properties that have been vacant, inherited, or owned by sellers who did not maintain regular payment — the arrears and penalties can be substantial. Check the RPT status at the City Treasurer’s Office and include any outstanding balance in your net proceeds calculation before setting an asking price.

Deduction 4: Broker Commission

If the property is listed through a licensed broker, the commission — typically 3 to 5 percent of the gross selling price — is deducted from the seller’s proceeds. On a PHP 3,000,000 sale at 5 percent, the commission is PHP 150,000. This is a significant deduction that must be included in the net proceeds calculation from the outset, not treated as an afterthought once a buyer appears.

Some sellers attempt to negotiate the commission down after a buyer appears, or to absorb it by raising the selling price. Both approaches create friction in the transaction. The commission is most cleanly handled as a known deduction that is factored into the asking price from the beginning.

Deduction 5: Outstanding Mortgage Balance

If the property has an outstanding bank mortgage, the mortgage balance must be settled at closing from the sale proceeds. The mortgage bank will require full settlement — outstanding principal plus any accrued interest and fees — and will release the mortgage annotation on the title only after this is confirmed. The net proceeds available to the seller after tax, commission, and RPT clearance are further reduced by the mortgage settlement amount.

A seller with an outstanding mortgage of PHP 1,500,000 on a unit selling for PHP 3,000,000 receives not PHP 3,000,000 less taxes and commission — they receive the amount remaining after taxes, commission, RPT arrears, and the PHP 1,500,000 mortgage settlement. Sellers with significant mortgage balances relative to their sale price should run this calculation carefully before listing, as the net proceeds may be considerably lower than anticipated.

The CGT miscalculation pattern is consistent and predictable. Sellers who are aware that CGT exists frequently compute it on the profit from the sale — the difference between what they paid and what they are selling for — rather than on the gross sale price or the zonal value. On a PHP 3,000,000 sale of a unit originally purchased for PHP 2,000,000, a seller who computes CGT on the PHP 1,000,000 profit estimates a CGT liability of PHP 60,000. The actual CGT liability, computed on PHP 3,000,000, is PHP 180,000. The underestimate is PHP 120,000 — a 200 percent error.

This is the most common form of seller shock in Philippine property transactions, and it is entirely avoidable by understanding the correct computation basis before setting an asking price. A seller who knows their CGT will be PHP 180,000 can price accordingly. A seller who estimates PHP 60,000 and discovers the reality at signing has already committed to a sale that produces less net proceeds than they planned for.

The most useful application of the net proceeds framework is in reverse: starting with the amount you need to walk away with, and computing the gross selling price required to produce that amount after all deductions.

If you need to net PHP 2,500,000 from a sale, and you are paying CGT, a 5 percent commission, and have no other deductions, you need to gross approximately PHP 2,870,000 to PHP 2,900,000 at the selling price — not PHP 2,500,000. Setting your asking price at PHP 2,500,000 because that is what you need would leave you approximately PHP 370,000 short after deductions.

Work through the calculation before listing. Identify your required net, add back each deduction in sequence — CGT computed on the expected selling price or zonal value, whichever is higher; commission; RPT arrears; mortgage settlement if applicable — and the resulting figure is the minimum gross selling price you need to achieve your objective. Your asking price should be set above that figure, not below it.

If the minimum gross price required by the calculation is above what comparable transactions support in your building and location, you have a pricing problem that the market will not solve for you. You either need to adjust your required net downward, wait for market conditions to support a higher price, or accept that the sale will not produce the outcome you need and reconsider whether to sell at all.

The most important thing about the net proceeds framework is when you use it. Sellers who run the calculation after agreeing to a selling price are doing damage control. Sellers who run the calculation before setting an asking price are making informed decisions.

The calculation takes thirty minutes with the right inputs: the expected selling price, the BIR zonal value, the current RPT status, and any outstanding mortgage balance. Those inputs are all available before you list. The seller who does this work before engaging a buyer, a broker, or a listing portal is in a position to set an asking price that actually produces the net amount they need — and to negotiate with a clear understanding of what concessions cost them in net terms, not just in headline price terms.

A PHP 100,000 price concession to close a deal feels different when you know it reduces your net proceeds by PHP 100,000 versus when you are calculating for the first time, at the table, how much you are actually going to walk away with. The framework exists so the second scenario does not happen to you.
