Philippine Legal and Tax Treatment
I. Introduction
The purchase of an electric vehicle by a VAT-registered consultant raises an important Philippine tax question: may the consultant claim input VAT on the purchase price of the electric vehicle?
The answer is not automatic. It depends on several factors, including:
- whether the seller charged VAT;
- whether the vehicle is used in the VAT-registered consultant’s taxable business;
- whether the purchase is supported by a valid VAT invoice;
- whether the vehicle is classified as a capital good;
- whether the vehicle is subject to any special VAT exemption;
- whether the Bureau of Internal Revenue may view the vehicle as a personal, non-business, or mixed-use asset; and
- whether the input VAT is deductible, amortizable, deferred, or disallowed under Philippine VAT rules.
In Philippine taxation, input VAT is not claimed merely because a buyer is VAT-registered. The taxpayer must establish that the VAT was properly passed on, that the purchase is connected with VAT-taxable activities, and that the documentary and substantiation requirements are satisfied.
For a VAT-registered consultant, an electric vehicle may be a legitimate business asset. A consultant may use it to visit clients, attend meetings, conduct site inspections, transport work materials, or perform professional services outside the office. However, because vehicles are commonly capable of personal use, the claim for input VAT on the purchase of an electric vehicle is likely to be scrutinized more closely than ordinary office expenses.
II. Basic VAT Framework in the Philippines
A. Nature of VAT
Value-added tax is an indirect tax imposed on the sale, barter, exchange, or lease of goods or properties and on the sale or exchange of services in the course of trade or business, as well as on importation of goods.
A VAT-registered consultant who renders professional services subject to VAT is generally required to:
- impose output VAT on taxable professional fees;
- issue VAT invoices;
- file VAT returns;
- remit excess output VAT over creditable input VAT; and
- maintain proper books and records.
The VAT system is designed so that VAT paid on purchases used in VAT-taxable business activities may generally be credited against VAT collected from customers or clients.
B. Output VAT and Input VAT
Output VAT is the VAT due on the taxpayer’s taxable sales or receipts.
Input VAT is the VAT due from or paid by the taxpayer on purchases of goods, properties, or services used in the course of business.
For a VAT-registered consultant, input VAT may arise from purchases such as:
- office rent;
- professional software;
- equipment;
- supplies;
- utilities;
- subcontracted services;
- vehicles used in the business; and
- other capital goods or operating expenses.
The key issue is whether the electric vehicle is considered a purchase used or to be used in the course of the VAT-registered consultant’s taxable business.
III. General Rule: Input VAT May Be Credited If Business-Related
A VAT-registered person may generally credit input VAT on purchases of goods, properties, and services against output VAT if the purchases are attributable to VAT-taxable activities.
Thus, if a VAT-registered consultant purchases an electric vehicle and the seller properly charges VAT, the input VAT may generally be creditable if:
- the consultant is VAT-registered at the time of purchase;
- the vehicle is purchased in the course of trade or business;
- the vehicle is used or intended for use in VAT-taxable professional services;
- the purchase is supported by a valid VAT invoice;
- the VAT is separately indicated in the invoice;
- the vehicle is recorded in the books as a business asset;
- the input VAT is reported in the VAT return; and
- no special rule disallows or limits the claim.
The consultant’s burden is to prove that the electric vehicle is not merely a personal asset but a business asset used in the conduct of taxable professional practice.
IV. Is the Purchase of an Electric Vehicle Subject to VAT?
A. General Rule on Vehicle Sales
The sale of motor vehicles by a VAT-registered seller is generally subject to VAT, unless a specific exemption applies. If the car dealer is VAT-registered and the transaction is VATable, the dealer should issue a VAT invoice and pass on VAT to the buyer.
If the seller is not VAT-registered, no input VAT may be claimed, even if the buyer is VAT-registered.
A VAT-registered buyer cannot claim input VAT unless VAT was actually passed on by a VAT-registered seller and properly documented.
B. Electric Vehicles and Philippine Tax Incentives
The Philippines has enacted laws promoting electric vehicles and related infrastructure, particularly under the Electric Vehicle Industry Development Act, or EVIDA. Electric vehicles may enjoy certain incentives, including tax and duty incentives, depending on the type of vehicle, source, and applicable implementing rules.
However, from a VAT input-tax standpoint, the crucial question is whether the specific purchase transaction was:
- subject to VAT;
- VAT-exempt;
- zero-rated; or
- not subject to VAT because of the seller’s status.
If the electric vehicle purchase is VAT-exempt, then no input VAT exists to be claimed by the buyer.
If the seller charged 12% VAT and issued a valid VAT invoice, the buyer may potentially claim input VAT, subject to the usual rules.
If the vehicle was imported, the VAT treatment may depend on importation rules, customs documentation, and whether VAT was paid to the Bureau of Customs.
C. VAT-Exempt Sale Means No Input VAT
A common mistake is assuming that because a purchase is tax-incentivized, the buyer gets input VAT. The opposite may be true.
If the law or regulation exempts the sale of the electric vehicle from VAT, then the buyer has no input VAT to claim because no VAT was imposed.
A VAT exemption benefits the buyer by reducing the purchase price, but it generally does not create creditable input VAT.
V. Consultant as VAT-Registered Buyer
A. Professional Consultants Are Engaged in Sale of Services
A consultant rendering services for a fee is generally engaged in the sale of services. If the consultant exceeds the VAT threshold or voluntarily registers as a VAT taxpayer, the consultant’s professional fees are subject to VAT unless exempt or zero-rated under a specific provision.
Examples of VAT-registered consultants include:
- management consultants;
- engineering consultants;
- IT consultants;
- business advisers;
- project consultants;
- financial consultants, subject to applicable rules;
- marketing consultants;
- technical specialists; and
- other independent professionals.
Where the consultant’s services are VAT-taxable, purchases used in rendering those services may generally give rise to creditable input VAT.
B. VAT Registration Is Necessary but Not Sufficient
VAT registration alone does not automatically validate an input VAT claim. The consultant must still show:
- the purchase was made in the course of business;
- the purchase is attributable to VATable sales or services;
- the invoice complies with VAT invoicing requirements;
- the expense or asset is properly recorded;
- the VAT was not claimed as part of deductible cost for income tax purposes if separately claimed as input VAT; and
- the transaction is not a sham, personal purchase, or improperly documented claim.
VI. Business Use Requirement
A. The Central Test
The central test is whether the electric vehicle is used or to be used in the course of the taxpayer’s trade or business.
For a consultant, business use may include:
- travel to client offices;
- travel to project sites;
- meetings with prospective clients;
- transport of work equipment;
- attendance at business conferences;
- official errands related to the consultancy practice;
- travel between branch offices or work locations;
- client servicing; and
- performance of field-based advisory work.
The more the consultant’s work requires mobility, the stronger the business-use justification.
B. Personal Use Risk
A vehicle is inherently susceptible to personal use. The BIR may question whether the vehicle is actually used for business or whether it is primarily a personal convenience.
Red flags include:
- the consultant has no employees or field operations;
- the consultancy is performed mostly online or from home;
- the vehicle is registered under the individual’s personal name without proper business records;
- there is no trip log or documentation of business use;
- fuel, charging, repairs, and insurance are not recorded consistently;
- the vehicle is used by family members;
- the vehicle is luxury or disproportionate to business needs;
- the taxpayer cannot connect the vehicle to taxable sales; or
- the vehicle is not recorded as a business asset.
C. Mixed Business and Personal Use
If the electric vehicle is used partly for business and partly for personal purposes, the taxpayer should be prepared to allocate the input VAT and related deductions according to actual business use.
For example, if the vehicle is used 70% for business and 30% for personal purposes, a conservative position is to claim only the business-related portion of input VAT, depreciation, insurance, repairs, and related expenses.
The Tax Code and VAT regulations do not always provide a simple mileage-based rule for every mixed-use case, but the principle remains: only purchases attributable to taxable business activities should generate creditable input VAT.
VII. Documentary Requirements
A. Valid VAT Invoice
To claim input VAT on the purchase of an electric vehicle, the consultant must have a valid VAT invoice issued by the seller.
The invoice should generally show:
- the seller’s registered name;
- the seller’s TIN;
- the seller’s VAT registration status;
- the buyer’s registered name;
- the buyer’s TIN;
- the description of the vehicle;
- the gross selling price;
- the VAT amount, separately indicated;
- the date of transaction;
- the invoice number;
- required BIR authority or invoice details, where applicable; and
- other information required under invoicing rules.
The invoice must be issued to the VAT-registered consultant, not to another person.
B. Invoice Must Be in the Taxpayer’s Name
If the consultant is a sole proprietor, the invoice should ideally be issued in the registered trade name or legal name associated with the VAT registration.
If the consultant operates through a corporation or professional corporation, the invoice should be issued to that corporation, not to the individual shareholder, officer, or employee.
A mismatch between the taxpayer claiming input VAT and the buyer named in the invoice can lead to disallowance.
C. Proof of Payment
Although VAT creditability primarily depends on the invoice and business use, proof of payment is still important for substantiation and audit defense.
Useful documents include:
- official receipt or collection receipt, if applicable;
- bank transfer confirmation;
- check voucher;
- financing documents;
- installment agreement;
- delivery receipt;
- sales contract;
- certificate of registration;
- insurance policy;
- OR/CR from the LTO; and
- accounting entries.
D. Vehicle Registration Documents
The LTO registration should align with the taxpayer’s business position.
If the vehicle is registered under the consultant’s personal name, that does not necessarily destroy the claim if the consultant is a sole proprietor and the business is legally tied to the same individual. However, the taxpayer must still show business use and proper accounting treatment.
If the buyer is a corporation but the vehicle is registered under an individual, the input VAT claim becomes much more vulnerable.
VIII. Capital Goods Treatment
A. Electric Vehicle as Capital Good
An electric vehicle used in business is normally a capital asset or depreciable property, not an ordinary operating expense.
For VAT purposes, capital goods generally refer to goods or properties with useful life exceeding one year and which are treated as depreciable assets for income tax purposes.
A vehicle used in business will usually fall under this category.
B. Input VAT on Capital Goods
The input VAT on capital goods may be creditable against output VAT, subject to VAT rules applicable at the time of purchase.
Historically, Philippine VAT rules contained special treatment for input VAT on capital goods exceeding a certain amount, including amortization over a period of months. Amendments under tax reform laws changed certain rules on amortization of input VAT on capital goods.
The current treatment should be checked against the applicable Tax Code provisions and BIR regulations for the taxable period in question. As a practical matter, taxpayers should determine whether the full input VAT may be claimed immediately or whether any transitional rule applies.
C. Accounting Treatment
The taxpayer should not simply expense the full vehicle cost. For income tax purposes, the vehicle is generally capitalized and depreciated over its useful life.
For VAT purposes, the VAT component, if creditable and separately claimed, should be recorded as input VAT rather than included in the depreciable cost.
For example, if the VAT-inclusive price is ₱2,240,000 and the VAT-exclusive selling price is ₱2,000,000 with ₱240,000 VAT:
| Item | Amount |
|---|---|
| Vehicle cost, VAT-exclusive | ₱2,000,000 |
| Input VAT | ₱240,000 |
| Total invoice price | ₱2,240,000 |
If the input VAT is claimed as creditable input VAT, the depreciable cost should generally be the VAT-exclusive amount of ₱2,000,000, not ₱2,240,000.
The taxpayer should avoid double benefit: claiming the VAT as input tax while also capitalizing and depreciating it as part of the asset cost.
IX. Timing of Input VAT Claim
A. Claim in the Proper Taxable Period
Input VAT should be claimed in the VAT return for the period when the purchase is properly supported and the input VAT becomes creditable under applicable rules.
For a vehicle purchase, the timing will usually be based on the VAT invoice date and the rules on purchases of goods or capital goods.
B. Installment Purchases and Financing
Many vehicles are acquired through financing. This creates additional issues.
Where a vehicle is purchased from a dealer and financed by a bank, the VAT invoice from the dealer may reflect the sale price and VAT. The buyer may pay a down payment, while the financing company pays the balance.
The input VAT claim depends on the nature and documentation of the sale, not merely on the fact that the buyer pays in installments.
Important documents include:
- dealer’s VAT invoice;
- chattel mortgage agreement;
- bank financing approval;
- schedule of payments;
- down payment receipt;
- statement of account;
- proof that the vehicle was sold to the taxpayer; and
- accounting entries.
The interest component of financing is separate from the VAT on the vehicle purchase. Interest may have its own tax treatment and is not part of the input VAT on the vehicle sale unless VAT is separately imposed on a taxable service by a VAT-registered entity.
X. Allocation Where Consultant Has Mixed VAT and Non-VAT Activities
A consultant may have:
- VAT-taxable services;
- VAT-exempt services;
- zero-rated services;
- non-business transactions; or
- compensation income from employment.
If the electric vehicle is used only for VAT-taxable consulting services, input VAT may generally be credited against output VAT.
If the vehicle is used partly for VAT-taxable and partly for VAT-exempt activities, input VAT may need to be allocated.
If the vehicle is used for non-business or personal activities, the input VAT attributable to such use should not be claimed.
Example
Assume a VAT-registered consultant provides both VAT-taxable advisory services and VAT-exempt educational services. The consultant buys an electric vehicle used for both lines of activity.
If actual use records show:
| Use | Percentage |
|---|---|
| VAT-taxable consulting | 60% |
| VAT-exempt educational work | 20% |
| Personal use | 20% |
A conservative VAT position is to claim input VAT only on the 60% attributable to VAT-taxable consulting, subject to applicable allocation rules.
XI. Electric Vehicle Used for Zero-Rated Services
If the consultant renders zero-rated services, input VAT may still be relevant.
Zero-rated sales are taxable sales subject to 0% VAT. A VAT-registered taxpayer engaged in zero-rated transactions may generally claim input VAT attributable to zero-rated sales, subject to refund or tax credit rules.
However, zero-rating in the Philippines is highly technical. The taxpayer must prove that the transaction qualifies for zero-rating under the Tax Code and applicable regulations.
Where the consultant’s services are zero-rated, the input VAT on an electric vehicle used in those services may be part of input VAT attributable to zero-rated sales, potentially recoverable through a VAT refund or tax credit certificate, subject to strict substantiation and filing deadlines.
XII. VAT Refund Considerations
If the VAT-registered consultant has excess input VAT, the excess may generally be carried over to succeeding periods. Refunds are more limited and usually arise in specific cases, such as zero-rated or effectively zero-rated sales.
A consultant who merely has regular VATable domestic sales usually credits input VAT against output VAT and carries over excess input VAT. A cash refund is not ordinarily available simply because the consultant bought an expensive vehicle and has excess input VAT, unless the taxpayer falls within a statutory refund situation.
If the consultant has zero-rated sales and claims a VAT refund, the electric vehicle input VAT will likely be examined carefully. The taxpayer must establish:
- VAT registration;
- zero-rated sales;
- valid invoices for sales and purchases;
- actual payment or incurrence of input VAT;
- attribution of input VAT to zero-rated sales;
- compliance with filing deadlines;
- proper accounting treatment; and
- absence of prior carry-over or double claim.
XIII. Income Tax Treatment Distinguished from VAT Treatment
VAT treatment should not be confused with income tax treatment.
A. VAT Input Tax
Input VAT is credited against output VAT. It is not the same as an income tax deduction.
B. Depreciation
The electric vehicle, being a business asset with useful life beyond one year, is generally depreciated over its useful life for income tax purposes.
C. Operating Expenses
Recurring expenses related to the electric vehicle may be deductible if ordinary, necessary, and business-related. These may include:
- electricity or charging costs;
- repairs and maintenance;
- insurance;
- registration;
- parking for business trips;
- tolls;
- cleaning;
- tires;
- batteries, where applicable; and
- other operating costs.
If these expenses are subject to VAT and supported by valid VAT invoices, the VAT component may also be creditable input VAT, subject to business-use allocation.
D. Personal Use Disallowance
Expenses attributable to personal use are not deductible for income tax purposes and should not generate creditable input VAT.
XIV. Withholding Tax Considerations
The purchase of a vehicle itself may not usually be treated like a regular professional service payment subject to expanded withholding tax, but taxpayers should consider whether any related payments may trigger withholding obligations.
Examples:
- payments for repair services;
- payments for charging station installation;
- lease of parking space;
- payments to contractors;
- payments to independent service providers;
- interest or financing charges, depending on payee and transaction type.
A VAT-registered consultant who is also a withholding agent may need to withhold on certain payments connected with the electric vehicle.
XV. Special Issues for Sole Proprietor Consultants
Many consultants operate as sole proprietors. In this case, the individual and the business are not separate juridical persons, but the tax registration and accounting records still matter.
A sole proprietor should ensure:
- the vehicle is recorded in the business books;
- the invoice bears the taxpayer’s registered name and TIN;
- the vehicle is used for business;
- personal use is tracked and excluded;
- depreciation is properly recorded;
- input VAT is claimed only to the extent allowed;
- the vehicle is included in fixed asset schedules;
- business travel is documented; and
- expenses are not mixed with purely household or family expenses.
A sole proprietor may have both professional income and personal consumption. Because of this overlap, the BIR may more closely examine whether the vehicle is genuinely used in the VATable consulting business.
XVI. Special Issues for Corporate Consultants
If the consulting practice is operated through a corporation, the analysis is stricter in certain respects.
The corporation should be the buyer of record. The VAT invoice, registration documents, insurance, and accounting records should ideally be in the corporation’s name.
If the vehicle is used by a shareholder, director, or officer, the corporation should document the business purpose. Otherwise, the BIR may treat the arrangement as:
- personal benefit;
- fringe benefit;
- constructive dividend;
- non-deductible expense;
- improperly claimed input VAT; or
- a transaction not directly connected to taxable business operations.
Where a corporate consultant allows an officer or employee to use the electric vehicle partly for personal purposes, fringe benefit tax and compensation tax issues may arise.
XVII. Fringe Benefit Tax Risk
For corporate taxpayers or employers, a vehicle made available to managerial or supervisory employees may give rise to fringe benefit tax if the use is personal or partly personal.
A consultant corporation that purchases an electric vehicle and assigns it to an executive should evaluate whether the arrangement creates a taxable fringe benefit.
This is separate from VAT but may affect the overall tax treatment and audit risk.
If the vehicle is demonstrably used for business operations and not for personal benefit, the fringe benefit risk is lower. Documentation is crucial.
XVIII. Audit Risks and BIR Scrutiny
The BIR may disallow input VAT on the purchase of an electric vehicle if:
- the invoice is invalid;
- the seller is not VAT-registered;
- the vehicle is not used in business;
- the vehicle is used primarily for personal purposes;
- the taxpayer cannot produce records;
- the vehicle is not recorded as a business asset;
- the input VAT was claimed in the wrong period;
- the VAT was also capitalized and depreciated;
- the taxpayer has no VATable sales to which the purchase relates;
- the purchase is excessive or unreasonable relative to the business;
- the taxpayer failed to allocate mixed use;
- the invoice is not in the taxpayer’s registered name;
- the transaction is VAT-exempt; or
- the input VAT was claimed despite lack of actual VAT passed on.
Because a motor vehicle is a high-value asset, it may attract audit attention.
XIX. Best Practices for Claiming Input VAT on an Electric Vehicle
A VAT-registered consultant planning to claim input VAT should observe the following best practices:
1. Ensure the Seller Is VAT-Registered
Before purchase, verify that the dealer or seller is VAT-registered and will issue a valid VAT invoice.
2. Check Whether the Transaction Is VATable
Confirm whether the specific electric vehicle sale is subject to VAT or exempt under applicable incentives.
3. Require a Proper VAT Invoice
The invoice should separately show the VAT amount and should be issued in the correct registered name and TIN of the consultant or consulting entity.
4. Record the Vehicle as a Business Asset
The vehicle should appear in the fixed asset register and books of accounts.
5. Maintain a Trip Log
A trip log is highly advisable. It should show:
- date of trip;
- destination;
- client or business purpose;
- odometer reading;
- driver;
- related project or engagement; and
- whether the trip was business or personal.
6. Track Charging Costs
Electric charging expenses should be supported by invoices or billing statements. Where home charging is used, the taxpayer should have a reasonable method for determining the business portion.
7. Allocate Mixed Use
Where personal use exists, only the business portion should be claimed for VAT and income tax purposes.
8. Keep Client Engagement Evidence
The consultant should retain engagement letters, contracts, emails, meeting invitations, site visit reports, and other documents linking vehicle use to taxable consulting work.
9. Avoid Double Claiming
Do not both claim the VAT as input VAT and include the same VAT in the depreciable cost of the vehicle.
10. Review Fringe Benefit Issues
For corporations or employers, determine whether the vehicle’s use by an officer or employee creates fringe benefit tax exposure.
XX. Sample Tax Treatment
Assume the following:
| Item | Amount |
|---|---|
| VAT-exclusive price of electric vehicle | ₱2,500,000 |
| VAT at 12% | ₱300,000 |
| Total invoice price | ₱2,800,000 |
The buyer is a VAT-registered consultant. The vehicle is used 80% for VAT-taxable consulting services and 20% for personal use.
A. Conservative VAT Claim
| Item | Amount |
|---|---|
| Total input VAT | ₱300,000 |
| Business-use percentage | 80% |
| Creditable input VAT | ₱240,000 |
| Non-creditable personal portion | ₱60,000 |
The ₱240,000 may be claimed as input VAT, assuming all requirements are met.
The ₱60,000 personal portion should not be claimed as creditable input VAT.
B. Income Tax Asset Basis
If the VAT attributable to business use is claimed as input VAT, the depreciable cost should generally exclude the claimed input VAT.
The treatment of the non-creditable VAT portion should be analyzed separately. Depending on facts, it may form part of cost or be treated as non-deductible personal expense to the extent attributable to personal use.
XXI. Common Mistakes
Mistake 1: Claiming Input VAT Without a VAT Invoice
A sales invoice, acknowledgment receipt, quotation, or delivery receipt that does not comply with VAT invoicing requirements may be insufficient.
Mistake 2: Claiming VAT on a VAT-Exempt Purchase
If the transaction is VAT-exempt, there is no input VAT to claim.
Mistake 3: Invoice Issued to the Wrong Person
A corporation cannot safely claim input VAT on a vehicle invoiced to its president personally.
Mistake 4: No Business-Use Records
The absence of a trip log or business-use evidence weakens the claim.
Mistake 5: Claiming 100% Input VAT Despite Substantial Personal Use
A full claim may be challenged if the vehicle is used personally.
Mistake 6: Capitalizing VAT and Also Claiming It as Input VAT
This creates a double tax benefit and may lead to disallowance.
Mistake 7: Treating Vehicle Purchase as an Ordinary Expense
The vehicle should normally be treated as a depreciable capital asset, not a one-time deductible expense.
Mistake 8: Ignoring Fringe Benefit Tax
Where a company vehicle is used by an employee or officer, fringe benefit tax may arise.
XXII. BIR Assessment Consequences
If the BIR disallows the input VAT claim, the consultant may face:
- deficiency VAT;
- interest;
- surcharge, where applicable;
- compromise penalties;
- disallowance of depreciation or expenses;
- possible withholding tax issues;
- fringe benefit tax assessment, where applicable; and
- documentary or bookkeeping violations.
The taxpayer may also lose the benefit of excess input VAT carry-over or refund claim if the input VAT is found invalid.
XXIII. Practical Legal Position
A VAT-registered consultant may claim input VAT on the purchase of an electric vehicle only if the vehicle purchase is VATable and the vehicle is used in the consultant’s VAT-taxable business.
The strongest position exists where:
- the consultant is VAT-registered;
- the seller is VAT-registered;
- the transaction is not VAT-exempt;
- a valid VAT invoice is issued;
- the vehicle is registered and recorded as a business asset;
- the consultant’s work requires travel;
- business use is documented;
- personal use is excluded or allocated;
- the input VAT is claimed in the correct VAT period;
- the vehicle is depreciated properly for income tax purposes; and
- the taxpayer avoids double claiming.
The weakest position exists where the vehicle is primarily personal, the invoice is defective, the vehicle is not in the taxpayer’s records, the transaction is VAT-exempt, or the consultant cannot show actual business use.
XXIV. Conclusion
Under Philippine tax law principles, the purchase of an electric vehicle by a VAT-registered consultant can give rise to creditable input VAT, but only when the statutory and regulatory requirements are satisfied.
The electric vehicle must be connected with the consultant’s VAT-taxable professional practice. The seller must have properly imposed VAT. The consultant must possess a valid VAT invoice. The vehicle must be recorded and treated as a business asset. If there is personal use, the input VAT should be reasonably allocated, and only the business-related portion should be claimed.
The fact that the vehicle is electric does not by itself determine the input VAT treatment. Electric vehicle incentives may affect whether VAT is imposed on the transaction at all. If the sale is VAT-exempt, there is no input VAT to claim. If the sale is VATable and VAT is properly passed on, the consultant may claim input VAT to the extent the vehicle is used in VAT-taxable business operations.
The core rule remains: input VAT is creditable only when it is validly imposed, properly documented, and attributable to the VAT-registered taxpayer’s taxable business activities.
