Key Takeaways
- Taiwan withholding tax is an advance income tax collection mechanism under which a payer may need to deduct tax when making specified payments and remit it to the tax authority.
- The applicable rate depends on the type of income, the status of the recipient, and, for foreign enterprises, whether the enterprise has a fixed place of business or business agent in Taiwan.
- For Taiwan-resident individuals, common withholding rates include 10% on commissions, interest, rent, royalties and professional practice income, while salary withholding generally follows the salary withholding table or a 5% election.
- For non-resident individuals, salaries are generally subject to 18% withholding, although a 6% rate can apply to lower monthly salary payments. Taiwan’s 2026 monthly minimum wage is NT$29,500, making the relevant 1.5-times threshold NT$44,250.
- A foreign profit-seeking enterprise without a fixed place of business or business agent in Taiwan may generally face 20% withholding on applicable Taiwan-source service or business income, but the effective tax burden may be reduced under approved methods, Article 25 of the Income Tax Act, or an applicable income tax agreement.
- Taiwan-source income must be identified before applying a withholding rate. The location of the payer alone does not determine the tax treatment.
- Non-resident withholding generally carries a much shorter reporting timetable: payment of tax and filing of the withholding statement are generally required within 10 days after withholding.
- From 1 January 2026, certain foreign electronic-service businesses registered for Taiwan VAT purposes also became withholding agents for relevant payments they make.
Introduction
Withholding tax is an important part of Taiwan’s income tax collection system. It affects salaries, interest, rent, commissions, royalties, professional fees and many cross-border payments made to foreign individuals and enterprises.
For businesses, the difficult part is rarely finding a single percentage. The correct treatment depends on several questions: Who is being paid? What kind of income is it? Is the income Taiwan-source? Is the recipient resident or non-resident? Does a foreign company have a fixed place of business in Taiwan? Does a special tax assessment method or income tax agreement apply?
This guide consolidates those issues into one practical framework for Taiwan withholding tax in 2026.
What Is Withholding Tax in Taiwan?
Withholding tax in Taiwan is a system under which a person or business making specified income payments deducts income tax at the time of payment and remits it to the tax authority. Article 88 of Taiwan’s Income Tax Act identifies income subject to withholding, while Article 92 establishes the principal remittance and reporting deadlines.
Withholding does not mean every payment is taxed at the same rate. The payer must first identify the recipient, income category and source before determining the applicable rate and filing procedure.
Who Is a Taiwan Resident or Non-Resident for Withholding Tax Purposes?
A common oversimplification is that an individual becomes a Taiwan tax resident only after spending more than 183 days in Taiwan.
Under Article 7 of the Income Tax Act, an individual is treated as residing in Taiwan if either:
- the individual has a domicile in Taiwan and resides in Taiwan on a regular basis; or
- the individual does not have a Taiwan domicile but stays in Taiwan for more than 183 days during a taxable year.
An individual who does not meet the statutory resident criteria is treated as a non-resident individual for income tax purposes.
The 183-day test is therefore important, but it is not the only statutory residence test.
For companies, the relevant withholding analysis is different. A foreign profit-seeking enterprise may be treated differently depending on whether it has a fixed place of business or business agent in Taiwan.
Taiwan Withholding Tax Rates at a Glance
The following table summarizes commonly encountered domestic withholding rates. These are Taiwan’s domestic rules before considering an applicable income tax agreement or an approved special tax computation.
Type of income | Taiwan resident / applicable local recipient | Non-resident individual or foreign recipient | Key point |
Salary | Salary withholding table or generally 5% election | Generally 18%; 6% may apply to qualifying lower monthly salary | Special salary thresholds apply |
Commission | 10% | 20% | Classification of payment matters |
Interest | Generally 10% | 15% for certain specified financial income; otherwise generally 20% | Treaty rate may be lower |
Rent | 10% | 20% | Applies to qualifying Taiwan rental income |
Royalties | 10% | 20% | Treaty relief may be available |
Professional practice income | 10% | Generally 20% | Specific exceptions may apply |
Pension / retirement income subject to withholding | 6% on taxable amount | 18% on taxable amount | Only taxable balance is relevant |
Structured-product income | 10% | 15% | Separate statutory category |
Dividends | Different domestic resident rules apply | Generally 21% | Treaty rate may reduce foreign-recipient withholding |
Other applicable Taiwan-source income of a foreign enterprise without a Taiwan fixed place of business or business agent | — | Generally 20% | Special relief may change the effective burden |
The rates are based on the Ministry of Finance’s withholding standards. The income category must be determined before selecting a percentage.
2026 Salary Thresholds
For 2026, Taiwan’s monthly minimum wage is NT$29,500. Accordingly, the 1.5-times minimum-wage threshold relevant to the reduced non-resident salary withholding rule is NT$44,250 per month. Qualifying non-resident salary at or below that level may be subject to 6% withholding rather than the ordinary 18% rate.
For resident individuals receiving non-monthly or part-time salary, the official 2026 withholding threshold is NT$90,501 per payment under the applicable salary withholding rules.
The Resident Small-Payment Rule Is Not a Universal NT$20,010 Threshold
A gross-payment figure such as NT$20,010 should not be treated as a universal statutory withholding threshold.
Under the official withholding standards, the general small-payment exemption for qualifying payments to Taiwan-resident recipients is based on the amount of tax that would otherwise be withheld. Where the withholding tax for a payment does not exceed NT$2,000, withholding may be exempt, subject to statutory exceptions.
The correct gross payment threshold therefore depends on the applicable withholding rate and income category.
What Income Is Considered Taiwan-Source Income?
Before determining the withholding rate, the payer should establish whether the payment represents Taiwan-source income.
Article 8 of the Income Tax Act includes several important categories of Taiwan-source income, including:
- remuneration for services rendered in Taiwan, subject to applicable statutory qualifications;
- interest obtained from Taiwan government bodies, enterprises, organizations or individuals;
- rental income from property situated in Taiwan;
- royalties from patents, trademarks, copyrights, secret formulas, franchises and similar rights made available for use in Taiwan;
- business profits from operations conducted in Taiwan; and
- other income obtained within Taiwan.
For cross-border contracts, the analysis may require more than checking the payer’s address. Businesses should examine the actual services performed, location of activities, rights being granted, contractual terms and applicable Taiwan-source-income guidance.
This distinction is particularly important for:
- consulting and technical-service agreements;
- software and cloud-service payments;
- licences of intellectual property;
- digital-platform transactions;
- bundled service-and-licence arrangements; and
- contracts involving both Taiwan and offshore activities.
Who Must Withhold Taiwan Income Tax?
Taiwan’s Income Tax Act identifies withholding agents for payments within the withholding system. Depending on the payment structure, the withholding agent may be a company, organization, institution, business operator or other person responsible for making the payment.
The withholding obligation normally arises when the payment is made, rather than when an invoice is issued.
Accordingly, businesses should determine the withholding treatment before releasing funds to the recipient rather than waiting until the annual tax reporting process.
What Are the Withholding Tax Payment and Filing Deadlines?
The deadlines differ materially between ordinary domestic withholding and payments to certain non-resident recipients.
Payments Under the General Withholding Timetable
For withholding falling within the ordinary timetable, tax withheld during a month generally must be paid to the tax authority by the 10th day of the following month.
Annual withholding statements generally must be filed by the end of January, with the relevant certificates issued to income recipients within the statutory timetable.
Payments to Non-Residents and Foreign Enterprises Without a Taiwan Fixed Place of Business
Where income is paid to a non-resident individual or to a foreign profit-seeking enterprise without a fixed place of business in Taiwan, the withholding agent generally must:
- withhold the tax when making the payment;
- pay the tax to the tax authority within 10 days; and
- file the required withholding statement within the same statutory period.
Special extensions can apply where the 10-day period includes at least three consecutive national holidays.
The short timetable is one reason cross-border payments should be reviewed before payment approval.
How Does Taiwan Withholding Tax Apply to Foreign Companies?
A foreign company that has no fixed place of business and no business agent in Taiwan can be subject to withholding on qualifying Taiwan-source income.
For applicable service remuneration or business income, the gross-payment withholding rate can often be 20% under the domestic rules. However, that does not mean every foreign service contract necessarily bears an effective 20% tax cost.
Depending on the facts, possible alternatives include:
- determining that all or part of the income is not Taiwan-source;
- applying for an approved net profit ratio and domestic profit contribution ratio;
- obtaining approval under Article 25 of the Income Tax Act where its conditions are satisfied; or
- applying an applicable income tax agreement.
Each method has different eligibility, documentation and approval requirements.
What Is the Correct Legal Basis for the Net Profit Ratio and Domestic Profit Contribution Ratio Method?
An earlier formulation referring to “Article 8, Section 15-1 of the Income Tax Act” is inaccurate.
The relevant mechanism is Article 15-1 of the Directions/Guidance for Determining Income from Sources in the Republic of China, used in connection with Taiwan-source service remuneration under Article 8, subparagraph 3, or business profits under Article 8, subparagraph 9 of the Income Tax Act.
An eligible foreign profit-seeking enterprise without a Taiwan fixed place of business or business agent may apply, generally before receiving the relevant payment, for approval to calculate Taiwan-source taxable income using an approved:
- net profit ratio (NPR); and
- domestic profit contribution ratio (DPCR).
A simplified conceptual formula is:
Taiwan taxable income = Relevant Taiwan-source revenue × approved NPR × approved DPCR
The withholding tax is then calculated by applying the applicable tax rate to that assessed Taiwan taxable income.
How Is the Net Profit Ratio Determined?
The tax authority may consider evidence such as:
- actual accounting records and supporting documents;
- profit ratios accepted for the same enterprise under comparable contracts in previous years;
- applicable industry profit standards; and
- the factual nature of the business activity.
How Is the Domestic Profit Contribution Ratio Determined?
Where activities occur both in and outside Taiwan, the enterprise should provide documents demonstrating how much of the profit-producing activity is attributable to Taiwan.
Evidence may include:
- contract terms;
- work scope;
- transaction and operating flows;
- location of personnel and activities;
- previous approved cases involving comparable transactions; and
- other records demonstrating the respective Taiwan and offshore contribution.
If the taxpayer cannot substantiate an appropriate allocation, the official rules may result in a substantially less favorable Taiwan contribution ratio.
Illustrative Example
Assume, solely for illustration:
- Taiwan-source contract revenue: NT$2,000,000
- approved NPR: 25%
- approved DPCR: 40%
- applicable tax rate: 20%
The assessed taxable income would be:
NT$2,000,000 × 25% × 40% = NT$200,000
The tax would then be:
NT$200,000 × 20% = NT$40,000
The NPR and DPCR in this example are hypothetical. They are not standard statutory ratios and should not be used without an applicable approval.
Main Tax Treatment and Relief Routes for Foreign Companies
Route | Tax base | Typical use | Approval / evidence |
Ordinary withholding | Relevant gross Taiwan-source payment | Default treatment where no special relief applies | Income-source and payment classification must still be correct |
Article 15-1 Taiwan-source-income method | Revenue × approved NPR × approved DPCR | Foreign enterprises earning qualifying Taiwan-source service remuneration or business profit | Application and supporting contract/business evidence required |
Income Tax Act Article 25 | Statutorily deemed percentage of gross revenue | Certain qualifying international transport, construction, technical-service, machinery-leasing and specified businesses | Prior approval is required |
Income tax agreement | Treatment determined under applicable agreement | Eligible residents of Taiwan’s treaty partners | Tax residence, income classification and treaty conditions must be established |
Article 25 permits approved foreign enterprises in specified businesses to use deemed-profit treatment where allocating costs and expenses is difficult. The statute provides a 10% deemed profit ratio for qualifying international transportation and 15% for other qualifying Article 25 businesses. With a 20% tax rate applied to the deemed income, this can produce an effective gross tax burden of approximately 2% or 3%, respectively, where the Article 25 treatment is validly approved.
Article 25 is not a general alternative available to every foreign service provider. The activity and conditions must fall within the statutory scope.
How Are Electronic Services and Royalties Distinguished for Taiwan Withholding Tax?
Cross-border digital transactions require particular care because a payment described commercially as a “technology fee” or “software fee” can contain different tax elements.
Under Article 8 of the Income Tax Act, a royalty can arise where consideration is paid for the use in Taiwan of rights such as:
- patents;
- trademarks;
- copyrights;
- secret formulas;
- franchises; or
- other qualifying intellectual-property rights.
An electronic or technical service, by contrast, may derive from the actual provision of services rather than the grant of a right to exploit intellectual property.
The contractual label is therefore not decisive. A business should consider:
- what the customer actually receives;
- whether intellectual-property rights are licensed;
- whether the customer receives only access to a service;
- where relevant services are performed or used;
- whether the arrangement contains separable service and royalty elements; and
- whether special rules for cross-border electronic services apply.
A single technology agreement may contain more than one tax character. Where that occurs, the components should be analysed based on their substance rather than automatically applying one withholding rate to the entire contract.
2026 Withholding-Agent Change for Foreign Electronic-Service Businesses
A significant change took effect on 1 January 2026.
Taiwan’s Ministry of Finance clarified that businesses registered for tax under Article 28-1 of the Value-Added and Non-Value-Added Business Tax Act—including relevant foreign platform and non-platform electronic-service businesses—can themselves become income tax withholding agents when making payments that fall within Taiwan’s withholding rules.
These businesses may therefore have obligations to:
- deduct withholding tax from qualifying payments;
- remit that tax;
- file withholding statements; and
- issue the required withholding certificates.
A foreign electronic-service business may perform these obligations directly or through an eligible Taiwan agent in accordance with the applicable rules.
This development concerns the withholding obligations arising from payments made by the business and should be distinguished from the business’s own Taiwan income tax or VAT obligations on its electronic-service sales.
How Can Taiwan's Income Tax Agreements Reduce Withholding Tax?
Taiwan’s domestic withholding rate is not always the final rate for a foreign recipient.
Where the recipient qualifies as a resident of a jurisdiction that has an applicable income tax agreement with Taiwan, the agreement may provide:
- a lower dividend withholding rate;
- a lower interest rate;
- a lower royalty rate;
- protection for business profits where the foreign enterprise does not have the required permanent establishment in Taiwan; or
- other relief depending on the type of income.
Treaty relief is not automatic merely because the recipient is incorporated in a treaty jurisdiction. Eligibility, tax residence, beneficial ownership where relevant, income characterization, permanent-establishment provisions and procedural requirements should be reviewed before relief is claimed.
Taiwan’s Ministry of Finance reports that 36 comprehensive income tax agreements and 13 international transportation income tax agreements have been signed and are in force. The applicable agreement should therefore be checked transaction by transaction rather than assuming the domestic withholding rate always applies.

What Documents Should a Foreign Company Prepare When Applying for Reduced Taiwan Tax Treatment?
Documentation requirements depend on the relief route, but foreign companies should generally be prepared to substantiate both the legal arrangement and the economic activity behind it.
Typical documentation can include:
- signed contracts and amendments;
- Chinese translations where required;
- invoices and payment information;
- detailed descriptions of services;
- transaction-flow diagrams;
- explanation of activities performed in and outside Taiwan;
- evidence supporting the net profit ratio;
- evidence supporting the domestic profit contribution ratio;
- financial information;
- prior Taiwan tax approvals for comparable transactions;
- certificate of tax residence where treaty relief is sought; and
- power of attorney where a Taiwan representative handles the application.
For an Article 15-1 application, the official directions specifically contemplate supporting contracts, Chinese translations, descriptions of business operations and transaction flows, evidence relevant to the ratios requested, and authorization documents where an agent applies.
Applications should be considered before payment rather than after the withholding event wherever prior approval is required.
What Are Common Taiwan Withholding Tax Mistakes?
1. Treating the 183-Day Rule as the Only Residence Test
Taiwan’s statutory residence definition also addresses individuals who have a Taiwan domicile and reside in Taiwan. The residence analysis should not automatically begin and end with a day count.
2. Using One Withholding Rate for Every Payment to an Overseas Company
A foreign recipient does not automatically mean 20% applies to every payment. The income source and character must first be identified.
3. Applying a Universal NT$20,010 Payment Threshold
The general small-payment withholding exemption for resident recipients is linked to the amount of tax otherwise required to be withheld, rather than one universal gross-payment amount.
4. Assuming All Software or Digital Payments Are Service Fees
Some contracts may contain royalty elements. Intellectual-property rights and the commercial substance of the arrangement should be examined.
5. Calling Article 15-1 Part of the Income Tax Act
The foreign-enterprise NPR/DPCR procedure is found in the Taiwan-source-income guidance associated with Article 8 of the Income Tax Act, not in an “Article 8, Section 15-1” of the Income Tax Act itself.
6. Applying for Relief After the Payment Has Already Been Made
Where advance approval is needed, waiting until after the withholding event can create unnecessary tax and refund issues.
7. Missing the Non-Resident 10-Day Deadline
The withholding and reporting period for qualifying non-resident payments is substantially shorter than the ordinary domestic monthly and annual timetable.
8. Ignoring an Applicable Income Tax Agreement
A domestic 20% or 21% rate should not be applied automatically without checking whether the foreign recipient can legitimately claim treaty treatment.
What Happens If a Withholding Agent Fails to Comply?
Taiwan’s Income Tax Act imposes penalties for withholding failures.
Where a withholding agent fails to deduct the required tax, the tax authority can require payment of the tax shortfall and supplemental reporting. A penalty of up to one time the amount of tax that should have been withheld may apply. If the withholding agent continues to fail to comply after being instructed to correct the violation, the penalty can increase to as much as three times the amount that should have been withheld.
Separate penalties can arise for failures involving withholding statements, certificates or other reporting obligations.
Because the potential exposure can exceed the original withholding amount, businesses making cross-border payments should build withholding review into the payment-approval process.
Taiwan Withholding Tax Compliance Checklist
Before making a potentially taxable payment, consider the following sequence:
- Identify the payee.
Determine whether the recipient is an individual or enterprise and whether it is resident, non-resident, domestic or foreign. - For a foreign enterprise, determine its Taiwan presence.
Confirm whether it has a fixed place of business or business agent in Taiwan. - Classify the income.
Determine whether the payment is salary, commission, interest, rent, royalty, professional remuneration, service income, business profit or another category. - Determine whether the income is Taiwan-source.
Review Article 8 and the applicable Taiwan-source-income rules rather than relying only on the payer’s location. - Identify the domestic withholding rate.
- Check for special treatment.
Consider Article 15-1 NPR/DPCR treatment, Article 25 or another applicable tax regime where appropriate. - Check the relevant income tax agreement.
Confirm whether the recipient qualifies for treaty relief and complete the procedural requirements. - Obtain approvals before payment where necessary.
- Withhold tax at the payment date.
- Remit and report within the correct deadline.
Pay particular attention to the 10-day rule for specified non-resident payments. - Retain supporting documentation.
Preserve contracts, source-of-income analysis, tax-residence documents, approvals, calculations and filing records. - Recheck rates and thresholds each year.
Salary thresholds and administrative rules can change even where the underlying legislation remains the same.
Conclusion
Taiwan withholding tax should not be treated as a simple rate table. The correct result comes from applying the rules in the right order: identify the recipient, classify the income, determine whether the income is Taiwan-source, establish the domestic withholding rate, and then consider any special assessment method or income tax agreement.
This is particularly important for foreign service providers, electronic-service businesses, technology contracts and royalty arrangements, where source rules and approved tax-computation methods can materially change the effective tax cost.
Businesses should therefore review withholding treatment before making payment, secure required approvals in advance and retain the documents supporting the tax position taken.
