Tax in Vietnam

Who is the tax authority and where do filings live?

The General Department of Taxation (GDT, Tong cuc Thue), under the Ministry of Finance, administers Vietnam's tax system through 63 provincial tax departments and district-level tax sub-departments [SC1]. The General Department of Customs (GDC, Tong cuc Hai quan) administers import-export duties and import VAT. Filings flow through the GDT's electronic tax portal (thuedientu.gdt.gov.vn) for VAT, PIT, CIT, foreign-contractor withholding tax (FCWT), and personal-income tax. Mandatory e-invoicing operating since 1 July 2022 channels invoice data directly to GDT in near-real-time. The Law on Tax Administration No. 38/2019/QH14 (effective 1 July 2020) governs procedure; the Law on Personal Income Tax No. 04/2007/QH12 (as amended by Law 26/2012, Law 71/2014, and other amendment laws) and Law on Corporate Income Tax No. 14/2008/QH12 (as amended by Law 32/2013, Law 71/2014, Law 03/2022) govern substance. The Law on Value-Added Tax No. 13/2008/QH12 (as amended) governs VAT. The credentialed Vietnamese tax-and-accounting professions are Kiem toan vien (auditor) regulated by the Ministry of Finance, Ke toan truong (chief accountant) under the Law on Accounting, and Tax Agent (Dai ly thue) regulated under Decree 51/2010/ND-CP and Circular 117/2012/TT-BTC for tax-specialist practice. Tax disputes proceed through GDT administrative review (Decision-on-Tax-Liability protest, Letter-of-Tax-Inspection objection) and then the People's Court system (district court for first instance, provincial court for appeal, Supreme People's Court for cassation). Sub-statutory law: Decree 132/2020/ND-CP (transfer pricing), Decree 126/2020/ND-CP (tax administration implementation), Decree 65/2013/ND-CP (PIT implementation), Decree 218/2013/ND-CP (CIT implementation), Decree 209/2013/ND-CP (VAT implementation), and successive Circulars implementing each.

What is the tax year and when are returns due?

The individual tax year is the calendar year. Annual PIT finalisation returns are due by the last day of the third month after year-end (31 March of the following year for self-finalising employees, or 30 April where the employer finalises and the employee has additional non-employment income) [SC1]. Monthly/quarterly PIT and VAT returns are due by the 20th of the following month or the last day of the first month of the following quarter. CIT is paid quarterly by the 30th of the month following each quarter (provisional CIT instalments based on actual quarterly performance, with the prior-year-based safe-harbour formula no longer available since Decree 91/2022/ND-CP), with annual CIT finalisation due by the last day of the third month after fiscal year-end. Foreign Contractor Withholding Tax (FCWT) returns are due by the 10th of the following month for the foreign-contractor's CIT plus VAT components withheld by Vietnamese payers. Late-payment interest accrues at 0.03 percent per day (10.95 percent annualised). Mandatory e-invoicing transmission to GDT applies to all enterprises since 1 July 2022 (Decree 123/2020/ND-CP and Circular 78/2021/TT-BTC), with B2B and B2C invoices flowing to GDT in near-real-time. The 30 December annual CIT-instalment-true-up calculation requires that aggregate quarterly CIT paid is not less than 80 percent of the actual annual CIT liability — a 20 percent safe-harbour shortfall threshold. The annual PIT finalisation also requires reconciliation between employer-withheld PIT and the actual progressive-bracket calculation including all employee deductions; over-withheld amounts are refunded via the GDT portal.

Who is a Vietnamese tax resident?

Under Article 2 of the PIT Law and Article 1 of Circular 111/2013/TT-BTC, an individual is tax resident if (a) physically present in Vietnam for 183 days or more in a calendar year or any 12-month period from first arrival, OR (b) maintaining a regular place of residence in Vietnam (registered permanent residence under Vietnamese household-registration framework, or a leased dwelling under a contract of 183 days or more in the tax year) [SC2]. Residents are taxed on worldwide income at progressive rates; non-residents are taxed on Vietnam-source income at a flat 20 percent on employment and 0.1-10 percent on other categories. The 12-month-rolling-period from first arrival creates a fact-pattern where foreign-national arrivals in mid-year may qualify as resident for the first 12-month period (counting forward from arrival) and then for subsequent calendar years on the calendar-year basis. Foreign individuals on assignment frequently sit between regimes mid-year and need careful day-counting plus host-country treaty consideration; the 183-day count includes arrival and departure days. Vietnamese citizens working abroad as long-term assignments may qualify as non-residents if they cease maintaining a Vietnamese registered residence and physically leave for the requisite period. Treaty residency tie-breakers under Vietnam's bilateral DTC network apply where two jurisdictions both treat a person as resident, with Foreign-Contractor Withholding Tax (FCWT) rules under Circular 103/2014/TT-BTC providing the operational framework for cross-border-services taxation. Non-resident status for foreign nationals on short-term assignments enables the 20 percent flat-rate-on-Vietnam-source-employment treatment, frequently more favourable than the resident worldwide-income progressive treatment for short-stay senior assignees.

What are the personal income tax rates?

Residents face seven brackets on employment income: 5 percent up to VND 60 million annual taxable income; 10 percent on VND 60 million to 120 million; 15 percent on VND 120 million to 216 million; 20 percent on VND 216 million to 384 million; 25 percent on VND 384 million to 624 million; 30 percent on VND 624 million to 960 million; and 35 percent above VND 960 million [SC1]. Personal deduction is VND 11 million/month (VND 132 million/year) under Resolution 954/2020/UBTVQH14 (raised from VND 9 million in 2020); dependent deduction is VND 4.4 million/month per qualifying dependent. Business and investment income face separate flat rates: 0.5-5 percent on business income (depending on activity — 0.5 percent on goods distribution and supply, 1 percent on transport, 2 percent on services, 1.5 percent on production/transport/services-with-goods, 5 percent on lease of assets, 2 percent on agency-and-brokerage), 5 percent on capital investment (interest from non-VND-deposit instruments, foreign-bond interest, dividends from foreign companies), 5 percent on royalties/franchising, 0.1 percent on securities transfers (gross, on each disposal), and 2 percent on real-estate transfers (gross, with elective alternative of 25 percent on net gain for individual sellers). Non-residents pay flat 20 percent on employment and source-specific rates on other Vietnam-source categories. Capital gains on shares: residents pay 0.1 percent on gross transfer value or alternatively 20 percent on net gain (for unlisted-share transfers between non-public-company shareholders). Inheritance and gifts of specified assets above VND 10 million face 10 percent flat tax. Insurance compensation, lottery winnings above VND 10 million, casino winnings (where applicable), and prize-promotion winnings are taxed at 10 percent flat. Social insurance contributions (8 percent employee + 17.5 percent employer for SI; 1.5 percent + 3 percent for HI; 1 percent + 1 percent for UI; capped at 20x base salary level) reduce taxable PIT base.

How does Vietnam's corporate tax work?

The standard CIT rate is 20 percent on taxable income (cut from 22 percent in 2014 and from 25 percent in 2009) [SC2]. Preferential rates of 10 percent and 15 percent apply to specific encouraged sectors (high-tech, infrastructure in difficult socio-economic areas, software production, environmental protection, supporting industries, agricultural-product processing in difficult areas) for 15 years (10 percent rate) or 10 years (15 percent rate), often combined with tax holidays of 4 years' full exemption plus 9 years' 50-percent reduction (the so-called '4+9' regime under Decree 218/2013/ND-CP Article 16). Encouraged-area projects in extremely difficult socio-economic areas may qualify for 10 percent for the entire project life. Oil and gas extraction is subject to elevated rates of 32-50 percent depending on the field, with petroleum-resource-tax overlay. From 1 January 2024, Resolution 107/2023/QH15 implements the Pillar Two Qualified Domestic Minimum Top-up Tax (QDMTT) and Income Inclusion Rule (IIR) at 15 percent for in-scope MNE groups (consolidated revenue at least EUR 750 million in two of the prior four fiscal years), reducing the effective benefit of the preferential regimes for affected groups [SC3]. The Pillar Two implementation accompanies a separate Investment Support Fund (Quy ho tro dau tu) under Resolution 106/2023/QH15 providing direct fiscal subsidies to qualifying MNE-group entities to partially offset the QDMTT bite — a Vietnamese-specific approach to retaining FDI competitiveness post-Pillar-Two. Tax loss carryforward: 5 years (must be used in chronological order); carryback unavailable. Transfer pricing under Decree 132/2020/ND-CP follows OECD Transfer Pricing Guidelines with master-file + local-file + CbCR documentation thresholds aligned with OECD principles for groups above VND 18 trillion consolidated revenue. Withholding tax on cross-border payments (Foreign Contractor Withholding Tax, FCWT, under Circular 103/2014/TT-BTC) operates as a hybrid CIT-VAT withholding mechanism: 5 percent CIT + 5 percent VAT (deemed) for general services; 0.1 percent CIT + 5 percent VAT (deemed) for trading-related; 10 percent CIT + 5 percent VAT for royalties; treaty rates apply for CIT component but not VAT.

What about VAT?

The standard VAT rate is 10 percent under the VAT Law No. 13/2008/QH12 (as amended). The government has applied a temporary 2-percentage-point cut to 8 percent for most goods and services as a stimulus measure in successive tranches: through 30 June 2024 under Resolution 110/2023/QH15, extended through 31 December 2024 under Resolution 142/2024/QH15, and further extensions into 2025 under subsequent National Assembly resolutions tracked by GDT and Ministry of Finance [SC4]. Excluded from the 8-percent rate are telecoms, finance/banking/insurance, real estate, metal products, mining (except coal), refined petroleum, and items subject to special consumption tax (SCT) — these remain at the 10 percent rate. Zero rate applies to exports (goods exported abroad, services consumed outside Vietnam, international transport, gold-bullion exports for processing), with strict input-VAT-credit-claim documentation requirements (export contract, customs declaration, bank-transfer evidence, foreign-customer-payment trail). The 5 percent reduced rate applies to essentials (clean water, healthcare services, education materials, agricultural products at first sale by farmer, fertilisers, animal feed, certain mechanical equipment for agriculture). Exempt categories include life insurance, medical insurance, banking-loan-and-credit-services, securities transfers, real-property transfers (excluding state-leased land), educational services, public broadcasting. VAT registration applies above VND 100 million annual turnover for individuals/households (raised under Decree 91/2022/ND-CP from VND 50 million); companies are mandatory regardless of size. Mandatory e-invoicing under Decree 123/2020/ND-CP and Circular 78/2021/TT-BTC has been operating for all enterprises since 1 July 2022, with strict authentication-via-digital-signature requirements and real-time data transmission to GDT — fundamentally restructuring the VAT-compliance environment from the legacy paper-invoice-and-monthly-reconciliation model. Cross-border digital services to Vietnamese consumers by non-resident vendors are subject to VAT under FCWT framework or under the 2022-introduced offshore-supplier registration regime under Decree 126/2020/ND-CP requiring direct GDT registration. VAT refunds are available for export businesses (input-VAT-credit balances above VND 300 million held for 3+ months) and for new investment projects in pre-revenue stages.

How are cryptoassets taxed?

Vietnam has no formal crypto tax law. The State Bank of Vietnam (SBV) does not recognise cryptoassets as legal tender or means of payment under SBV Circular 09/2014/TT-NHNN and successive guidance reinforcing this position; using crypto as a means of payment is administratively prohibited under Decree 88/2019/ND-CP with administrative fines on payment-instrument violations. The Ministry of Finance has issued draft frameworks (most recently the Decision 1437/QD-TTg policy roadmap on digital asset industry development) but no operative tax statute. In practice, crypto trading by individuals is not subject to PIT under current rulings (because it falls outside the listed taxable income categories under Article 3 of the PIT Law — the 'investment income' category requires regulated-financial-instrument character which cryptocurrency does not meet), though the National Assembly's draft Law on the Digital Asset Industry (under consideration through 2025-2026) will likely change this framework substantially [SC5]. Several Supreme Court rulings have confirmed that cryptocurrency disposals do not constitute taxable income under the current PIT framework — the Ben Tre Provincial People's Court ruling 22/2017/HC-ST and subsequent appeals are the principal precedents. Crypto-related corporate revenue is subject to 20 percent CIT under general income provisions: companies engaged in cryptocurrency trading, mining operations, or providing exchange/wallet services account for revenue under accounting standards and pay CIT on net profit. Mining-rig importers face customs-duty and import-VAT exposure on equipment imports. Practitioners should track Ministry of Finance circulars closely; the draft digital-asset-industry law contemplates dedicated crypto-tax framework potentially including PIT on individual disposals and clarified VAT treatment, with implementation expected in the 2026-2027 horizon. NFTs and stablecoins fall in the same regulatory uncertainty pending the dedicated framework. The 2024-2025 SBV regulatory sandbox for fintech and digital-asset business models has progressively explored licensing structures.

What is the treaty network and what are the audit triggers?

Vietnam has approximately 80 active double tax treaties [SC1]. Treaty benefits require Foreign-Contractor Withholding Tax (FCWT) procedures and Form 02-DCNCT-TNDN documentation submitted to the GDT, supported by Tax Residency Certificate (TRC) of the foreign-counterparty and beneficial-ownership confirmation. Vietnam signed the OECD MLI on 7 June 2017 (deposit of ratification still pending as of 2025), so most treaty modifications still flow via bilateral protocols rather than multilateral synchronous changes; this creates per-treaty timing variation that practitioners must track individually. Audit triggers include: FCWT under-declaration on cross-border services (a perennial focus area, particularly for software-licence-and-cloud-services payments to overseas vendors); transfer-pricing non-compliance under Decree 132/2020/ND-CP (which mandates contemporaneous documentation, master file, local file, and CbC report for in-scope groups); invoice anomalies on the e-invoicing system mandatory for all enterprises since 1 July 2022 (with GDT risk-engine flagging via real-time data analysis); unexplained capital injections relative to declared profitability (the unaccounted-net-worth-growth presumption framework under Article 43 of the Tax Administration Law); CRS-driven foreign-bank-balance flagging (Vietnam acceded to CRS effective 2024 with first exchanges in 2025); and the post-Pillar-Two GIR (GloBE Information Return) reconciliation gaps for in-scope MNE groups. Standard statute of limitations is 5 years for additional assessment under Article 110 of the Tax Administration Law; 10 years where evasion is established. Penalties for tax evasion under Article 200 of the Penal Code can reach 1-3 times the underpaid tax plus criminal prosecution with imprisonment of 6 months to 7 years for grossly-significant evasion (VND 1 billion+ thresholds scaled by aggravating factors); administrative fines under Decree 125/2020/ND-CP range from 1 to 3 times the underpaid amount for tax-evasion violations and 0.03 percent per day default interest applies on the underlying liability.

What are the common penalties and pitfalls for foreigners?

The Vietnamese penalty framework under Decree 125/2020/ND-CP imposes administrative-fine sanctions for late filings (VND 2-15 million depending on violation severity), failure to file (escalating up to VND 25 million and assessment-by-GDT-estimate exposure), incorrect declarations (10-20 percent surcharge on underreported tax for ordinary cases; up to 3x for tax-evasion intent), and failure to maintain accounting records (VND 5-25 million plus reconstruction-by-tax-authority exposure) [SC6]. Default interest accrues at 0.03 percent per day on unpaid tax (10.95 percent annualised). Tax-evasion criminal exposure under Article 200 of the Penal Code carries imprisonment of 6 months to 7 years for grossly-significant evasion above VND 1 billion threshold, with progressive aggravation for organised or sophisticated schemes. Common foreign-national pitfalls: (1) the 12-month-rolling-period residency calculation from first arrival creates fact-patterns where foreign nationals become Vietnamese tax residents on a rolling basis even when they may have planned for non-resident status under the calendar-year framework — careful day-counting and treaty-tie-breaker analysis is required for cross-year assignments; (2) Foreign Contractor Withholding Tax (FCWT) under Circular 103/2014/TT-BTC operates as a hybrid CIT-VAT withholding mechanism that cannot be fully neutralised by treaty access (the VAT component of FCWT is not treaty-relief-eligible) — overseas service providers and Vietnamese payers need careful contract structuring to allocate FCWT economic burden; (3) Pillar Two QDMTT and IIR under Resolution 107/2023/QH15 effective 1 January 2024 caught many in-scope MNE groups operating through Vietnamese encouraged-sector preferential-rate vehicles, whose effective tax rate jumped from 5-10 percent to 15 percent overnight — the Investment Support Fund under Resolution 106/2023/QH15 provides partial subsidy offset but requires affirmative application; (4) e-invoicing mandatory transmission to GDT since 1 July 2022 created compliance disruption for foreign-managed enterprises whose accounting systems were not GDT-API-integrated; (5) the 2 percent minimum-revenue safe-harbour quarterly CIT instalment threshold under Decree 91/2022/ND-CP eliminated the prior-year-based safe-harbour, requiring real-time profitability tracking for quarterly CIT calculation; (6) Treaty-relief application via Form 02-DCNCT-TNDN requires GDT pre-approval for many treaty articles — failure to obtain pre-approval before payment results in full FCWT withholding with refund only via subsequent claim within 6 months; (7) the 80 percent quarterly-CIT-of-annual-CIT safe-harbour under Decree 126/2020/ND-CP creates year-end true-up risk where quarterly instalments fell short — the gap is paid with default interest from the 30 January following year deadline; (8) the personal-deduction VND 11 million/month threshold has been static since 2020 and inflation has eroded its protective value — taxpayers should ensure dependent-deduction claims are properly substantiated for every dependent claimed; (9) cross-border digital-services VAT registration under the offshore-supplier framework introduced 2022 has been progressively enforced with GDT increasingly tracking foreign-supplier non-compliance via payment-flow analysis; and (10) cryptocurrency disposals are not yet PIT-taxable under current rulings but the draft Digital Asset Industry Law contemplated for 2026-2027 enactment will close this gap — Vietnamese-resident crypto holders should track legislative developments and consider documentation of acquisition-cost-basis to prepare for retroactive-equivalent computation should the framework apply with look-back provisions.
