Income evidence supports visas, tenancy and credit applications abroad. The figures on payslips, the salary certificate and the bank statement must reconcile with one another.

Legal status: Thailand deposited its instrument of accession to the 1961 Hague Apostille Convention on 30 June 2026; it enters into force for Thailand on 28 February 2027 (source: HCCH). Until then, Thai employment documents used before a foreign employer, professional body or immigration authority follow the existing route: an original signed by a person with real authority (or an agency-certified copy), a translation into the required language, legalisation of that translation by the Department of Consular Affairs, and, where required, endorsement by the destination country's embassy in Bangkok. Note that an apostille or legalisation authenticates only the signature and seal — it does not certify that the statements in a certificate of employment are true. A destination employer may still verify them with your employer.

Income evidence is never read document by document; it is read as a set that must reconcile. An assessor compares the net figure on the payslip with the credit that landed in the bank account that month. If they differ with no explanation — a welfare loan deduction, a split payment — the whole set is questioned. Preparing a short explanation with supporting proof up front materially improves credibility.

A payslip is issued by the employer, and a salary certificate is the employer's confirmation of regular income. Both are private documents, so both need signature certification by a Notarial Services Attorney before consular legalisation. Bank statements certified by the bank follow their own separate route.

How many months you need is entirely the receiver's call: three, six or twelve, and often with a rule on how recently the document must have been issued. Asking precisely first and running the chain once is cheaper than over-preparing and finding documents have aged out while queuing.

Where income includes variable elements such as commission or bonus, have the certificate separate fixed pay from variable pay. Most assessors calculate on fixed income only; lumping everything together usually triggers a request for more documents and another round.

Documents to prepare

Payslips for the number of months the receiver requires
A salary certificate on company letterhead signed by an authorised person
Bank statements for the same period, certified by the bank
A recently issued company affidavit for the employer
The applicant's passport, plus explanations for any unusual account entries

Step order

Confirm with the receiver how many months, in what format, and how recently issued
Collect payslips and the salary certificate; check the figures against the bank statements
Have an authorised person sign, then certify the signature with a Notarial Services Attorney
Translate the whole set consistently, using identical terminology for each deduction and allowance
Legalise the translations at the Department of Consular Affairs, then the destination embassy where required

Pre-filing checklist

Each month's net pay reconciles with the credit in the bank account for that month
The salary certificate separates fixed pay from variable pay
Currency is stated on every document and the date format is uniform across the set
The payee name on payslips matches the bank account holder and the passport
Every document is still within the receiver's validity window on the actual filing date

Practical tips

Prepare a one-page month-by-month reconciliation between payslips and bank credits; it speeds up assessment considerably
If you are paid in cash, obtain signed payment receipts and withholding-tax evidence to support it
Never crop or redact bank statements — any alteration destroys the credibility of the whole set
If an unusual lump sum landed in the account, prepare evidence of its source in advance

Common pitfalls

Submitting system-printed payslips with no employer signature or seal, which makes signature certification impossible
A certificate quoting a total that includes bonus, so the receiver cannot reconcile fixed pay with the payslips
Documents issued too long before filing under the receiver's recency rule, forcing a full re-issue
Translating tax and social security deductions with different wording on each document, suggesting a different pay structure

Frequently asked questions

How many months of payslips are needed?

There is no universal standard; it depends on the receiving authority or embassy. Three to six months is common. Ask for the requirement in writing before preparing anything.

Are payslips printed from an online portal acceptable?

Yes, where HR certifies them as true copies and an authorised person signs, because signature certification needs a real signature to certify.

Do I need both payslips and a salary certificate?

Many receivers want both: payslips show actual monthly payments, while the certificate confirms current employment status and regular income.

Who certifies bank statements?

The issuing bank. That is a separate route from employer-issued documents, so allow time for the two chains to run in parallel.

How do I prove income paid in cash?

Use signed payment receipts together with withholding-tax evidence and social security records for the same period, so the set reconciles.

Should figures be converted into the destination currency?

Generally not within the document itself — keep the original Thai baht figures and state the currency clearly. If the receiver wants an indicative conversion, attach it as a separate supporting sheet.
