Proof of income at a glance
Document- Also called

- Issued by
- Your employer's HR or payroll department if salaried; your accountant or tax adviser if self-employed or a business owner; or your home country's tax authority
- Which issuer applies depends entirely on your employment situation
- Used for
- The consolidated income-verification document for a mortgage application, a bank or developer's proof-of-funds review, or a TRC financial-means file
- Distinct from payslips (raw monthly records) and an employment contract (the underlying agreement) — never a title or ownership document
- Typical cost
- Usually free from an employer; €30–€100 if issued by an accountant or tax adviser
- Translation and notarisation for local use are billed separately, typically €30–€100
- Validity
- No fixed legal validity period

- Language
- Issued in your employer's or accountant's own language
- A certified Vietnamese translation plus notarisation is generally required for local submission
- Legally required to buy?
- No — but one of the most frequently requested income documents
- Local mortgage financing is generally unavailable to non-resident foreigners, so most buyers finance from abroad and rely on this document there
- Who typically asks for it
- Your home-country lender if financing, the receiving Vietnamese bank or developer's finance team for KYC, or immigration authorities for a TRC file
- Confirm the exact format and period requested before you order one
How to obtain your proof of income for a Vietnam purchase
⏱ A few days to about two weeks, done in parallel with the rest of your proof-of-funds file
Proof of income is not a Vietnamese-issued document, and there is no single official template to fill in — the work is confirming which version applies to your situation, requesting it from the right issuer, and packaging it correctly for a cross-border file. Most buyers complete this step alongside the rest of their income and proof-of-funds documents rather than as a separate task.

Identify which version applies to your situation
⏱ 1–3 days◈ Usually free to a modest accountant's fee
Salaried employees ask their HR or payroll department for a signed salary certificate stating current role, income and length of service. Self-employed buyers, freelancers and company owners ask their accountant or tax adviser for a signed income letter based on recent financial statements or tax filings — never try to fabricate an equivalent employer certificate if you do not have one.
DocumentsEmployee ID or payroll contact · Recent financial statements (self-employed)
⚠Asking for the wrong type of certificate — for example a generic employment letter when a figures-based income certificate was requested — is a common reason a file is sent back.

Confirm exactly what your lender or counterparty needs
⏱ Same day◈ No direct cost
Ask your home-country lender, the receiving Vietnamese bank, the developer or your lawyer precisely which period the certificate should cover, whether it must state an exact figure or an income range, and whether they also want it alongside payslips, bank statements or an employment contract. Requirements differ meaningfully between a mortgage application, a bank's proof-of-funds review and a TRC financial-means file.
⚠Ordering a generic certificate before confirming the exact wording a lender wants can mean requesting a second, corrected version later.

Request the certificate from the right issuer
⏱ 2–5 business days◈ Usually free to €100
Have HR or your accountant issue a dated, signed letter on official letterhead, stating your name, income figures, currency and the period covered — stamped or sealed where that is standard practice for the issuer. A bare printout of numbers with no letterhead, signature or issuer contact details is routinely treated as unverifiable.
DocumentsRecent payslips or financial statements · Proof of identity
⚠A certificate with no signature, date or issuer contact details is one of the most common reasons a proof-of-funds file stalls.

Translate and notarise it for local use
⏱ 2–5 business days◈ €30–€100 (≈ VND 800,000–2.7 million)
If the certificate will be filed with a Vietnamese bank, developer, lawyer or immigration office, have it rendered into Vietnamese by a certified translator and notarised — the same requirement that applies to any foreign-language paperwork used locally. The original-language certificate alone is rarely accepted on its own by a Vietnamese counterparty.
DocumentsOriginal income certificate · Certified Vietnamese translation
⚠Translating before your lender or receiving bank has confirmed the exact wording and period they need risks paying for it twice.

Package it with the rest of your income and funds file
⏱ Immediate◈ Included above
Submit your proof of income alongside payslips, your employment contract and bank statements as one coherent income and proof-of-funds pack, with figures that reconcile against each other — lenders and Vietnamese banks alike process a complete, internally consistent file faster than a single certificate sent on its own.
⚠A certified income figure that does not match the amounts shown on your payslips or bank statements is one of the fastest ways to trigger extra scrutiny — reconcile the two before you submit.

Frequently asked questions
Do I need proof of income to buy property in Vietnam?
No — it is not a legal requirement to purchase or hold title. It is supporting evidence that a lender, receiving bank, developer or immigration file may ask for, separate from the ownership documents that establish your rights under the Housing Law 2023.
What counts as proof of income if I'm self-employed?
An accountant's or tax adviser's signed income letter, based on your recent financial statements or tax filings, replaces an employer's salary certificate. Company financials and tax returns can support it. Tell whoever is requesting the file that you are self-employed so they can confirm exactly what they will accept.
How is proof of income different from payslips or an employment contract?
Payslips are your raw monthly pay records and an employment contract is the underlying agreement with your employer. Proof of income is a separate, consolidated certificate — usually one signed page stating your income level and source — that some banks, developers and immigration files specifically ask for instead of, or in addition to, the other two.
Can I use proof of income to get a mortgage for a Hanoi property?
Local mortgage financing is generally unavailable to non-resident foreigners in Vietnam, so most buyers finance from abroad instead. There, proof of income — alongside payslips and bank statements — is exactly the kind of evidence a home-country lender will ask for.
Does my proof of income need to be translated into Vietnamese?
Yes, if it will be filed with a Vietnamese bank, developer, lawyer or immigration office. A certified Vietnamese translation plus notarisation is generally required — the original-language certificate alone is rarely accepted by itself for local use.
How recent does my proof of income letter need to be?
There is no fixed statutory validity period. In practice, lenders, banks and immigration files generally want a certificate dated within the last one to three months, so request it close to when you actually plan to submit your file.
Is proof of income enough for a temporary residence card application?
Usually not on its own. If your TRC route requires evidence of financial means, proof of income typically sits alongside payslips, an employment contract or bank statements. Confirm the exact file with a licensed adviser, since requirements are handled case by case.
