About Tax Law in Bang Khen, Thailand

Tax in Bang Khen is governed by national Thai law and administered locally. The Revenue Code of Thailand sets the framework for personal income tax, corporate income tax, value added tax, withholding tax, specific business tax, and stamp duty. Local levies such as land and building tax and signboard tax are administered in Bangkok by the Bangkok Metropolitan Administration and its district offices, including the Bang Khen District Office.

Businesses and individuals in Bang Khen face the same national rules as elsewhere in Thailand, but compliance and interactions typically occur through the local Area Revenue Office for registration, filings, audits, and queries, and through the Bang Khen District Office for local property related taxes. This means that while the rules are national, the practical steps, timelines, and contacts are local.

Why You May Need a Lawyer

Thai tax law is rule heavy and deadline driven. A lawyer can help interpret the Revenue Code and related regulations, choose the correct tax positions, and minimize disputes with authorities. Common situations include starting or restructuring a business, registering for VAT, handling payroll and withholding, buying or selling property in Bang Khen, dealing with cross border payments, managing transfer pricing between related companies, responding to a Revenue Department audit or assessment, seeking tax refunds, and negotiating penalty reductions or compromises.

Expatriates and digital businesses often need guidance on tax residence, permanent establishment risk, VAT on electronic services, and the taxation of foreign sourced income remitted to Thailand. Property owners in Bang Khen may require advice on land and building tax, signboard tax, and transaction taxes when transferring real estate. A lawyer can also assist with appeals to the Revenue Department and the Tax Court if disagreements arise.

Local Laws Overview

Governing framework. The key laws are the Revenue Code and its regulations and rulings, the Land and Building Tax Act B.E. 2562, the Signboard Tax Act, and the Civil and Commercial Code for instruments subject to stamp duty. Thailand has many double tax treaties that can reduce withholding tax on cross border payments. Transfer pricing rules require related party documentation for companies meeting statutory thresholds.

Tax types you will commonly encounter. Individuals are subject to progressive personal income tax on Thailand sourced income and on certain foreign sourced income remitted to Thailand as described below. Companies pay corporate income tax, generally at 20 percent, with separate rules for small and medium enterprises. VAT is generally 7 percent on the supply of goods and services in Thailand and on imports, with exemptions for specific activities. Specific business tax applies to certain sectors such as banking and real estate trading. Stamp duty applies to specified instruments, including leases and share transfers. Withholding tax applies to many payments such as salaries, service fees, rent, dividends, interest, and royalties. Local taxes include land and building tax on property holdings and signboard tax on commercial signage.

Residency and foreign income. A person who stays in Thailand for 180 days or more in a calendar year is typically a tax resident. Residents are taxable on Thai source income and, under current policy, on foreign source income that is brought into Thailand. From 1 January 2024 the Revenue Department applies the rule that foreign source income remitted into Thailand by a resident is taxable when it is received in Thailand, even if the income was earned in a prior year. Double tax relief may be available under treaties or foreign tax credits in appropriate cases.

Registration and thresholds. Juristic persons and individuals engaged in business must obtain a taxpayer identification number. VAT registration is generally required once taxable turnover reaches 1.8 million baht in a 12 month period. Foreign providers of electronic services to Thai consumers may have separate VAT registration obligations under the non resident e service regime.

Filing cycles and key deadlines. Personal income tax returns for the prior calendar year are due at the end of March for paper filing, with e filing typically granted a short extension into April. Companies file an annual corporate return within 150 days after the accounting year end and a half year return two months after the first six months. VAT returns are normally due monthly in the following month. Withholding tax returns on salaries and supplier payments are due monthly. Deadlines may differ for e filing and are periodically adjusted, so always confirm the current due dates.

Property and local taxes in Bang Khen. The Bang Khen District Office administers land and building tax and signboard tax. Annual property assessments are issued and payment is typically due in the first part of the year. On property transfers, national transaction taxes may apply, such as a transfer fee, specific business tax in certain cases, and stamp duty when applicable. These are collected at the Land Office handling the transfer, but ongoing annual property tax is handled by the district office.

Rates and withholding. Domestic withholding rates vary by payment type and recipient, for example 3 percent on many service fees paid to Thai companies, 5 percent on certain rental payments, and specific rates on dividends, interest, and royalties. Payments to non residents are often subject to 15 percent withholding unless reduced by a treaty. Because rates and classifications can be technical and change over time, verify the correct rate for your specific transaction before paying.

Audits, assessments, and penalties. The Revenue Department can review returns and issue assessments within statutory limitation periods. Surcharges and administrative fines can apply for late filing, late payment, or underpayment. Taxpayers generally have the right to file an objection with the Revenue Department within a set time after receiving an assessment, and to appeal further to the Tax Court if needed. Keep tax invoices, receipts, contracts, and accounting records for at least five years, and longer if you are under audit or have ongoing disputes.

How do double tax treaties help and how do I claim benefits?

Thailand has treaties that can reduce withholding tax on cross border payments and provide relief from double taxation.

Next Steps

Clarify your objectives and timeline. Identify whether your issue involves registration, filing, refunds, an audit, a property transaction, cross border payments, or a potential dispute. Note any deadlines stated in notices you have received.

Gather documents. Collect tax IDs, past returns and receipts, withholding certificates, tax invoices, contracts, payroll records, bank statements, property title documents, and any correspondence with authorities. Organizing these early saves time and fees.

Consult a qualified lawyer or tax professional in Bangkok. Ask about their experience with Revenue Department matters, Bang Khen District issues, and your specific industry. Request an engagement letter that outlines scope, fees, and deliverables. If representation is needed, prepare a power of attorney for dealings with the authorities.

Check your registrations and systems. Confirm VAT registration status, withholding practices, e invoicing and e filing access, and document retention procedures. Correcting process gaps early reduces penalty exposure.

Plan for resolution. If you face an audit or assessment, discuss strategy for submissions, penalty mitigation, settlement, or appeal. If you are planning a transaction, obtain a written tax analysis, confirm withholding and stamp duty obligations, and align contract terms with tax outcomes.

Monitor changes. Tax rules and rates can change, such as VAT rate extensions, treaty updates, and policies on foreign source income. Recheck requirements before filing or remitting funds to avoid surprises.
