What is a proof of income letter?

A proof of income letter is a formal document used to confirm that an individual has a stable income or salary. It is usually issued by an employer, financial institution, organisation, or—when necessary—by the individual in the form of a self-declaration. Proof of income letters are widely used during financial checks, loan or mortgage applications, tenancy agreements, embassy procedures, KYC verification, and various compliance-related processes.

Why institutions request proof of income

Many organisations require income verification to ensure financial stability, assess creditworthiness, or evaluate the ability to pay rent or loans. The letter provides assurance that the individual receives regular, documented income and helps prevent fraud or misrepresentation.

1. Banks and financial organisations

Banks require proof of income for a wide range of services, including:

• opening a bank account (especially in regulated markets);
• KYC and AML verification;
• loan or mortgage applications;
• credit card approval;
• debt restructuring;
• financial compliance checks.

A clear and professionally written proof of income letter speeds up approval and reduces requests for additional documentation.

2. Landlords and property managers

Proof of income is a standard requirement for rental applications worldwide. Landlords use it to verify that a tenant can consistently meet financial obligations. Some property managers accept only employer-issued letters, while others may accept general proof of income or self-declarations supported by additional evidence.

3. Embassies and consulates

Embassies frequently ask for income confirmation during visa applications to ensure the applicant has sufficient financial means. Salary confirmation letters from employers are widely accepted when combined with bank statements or tax declarations.

4. Employers and HR departments

Employers sometimes request income verification when transferring staff abroad, issuing relocation documents, completing internal audits, or supporting employee applications for tenancy or financial services.

5. Government and social services

Income verification may be required for government aid programs, social benefits, tax adjustments, and administrative procedures depending on the jurisdiction.

What information must be included in a proof of income letter

To ensure acceptance by banks, landlords, embassies, or authorities, the letter must contain clear and accurate financial details. These usually include:

• Full name of the individual;
• Employer or organisation name (if applicable);
• Income amount — salary, wages, or other income;
• Payment frequency — weekly, monthly, yearly;
• Employment position (for employer letters);
• Currency and format of income;
• Contact details for verification;
• Date of issue;
• Signature — handwritten or digital.

The letter must not contain confidential corporate data unless specifically required by the receiving organisation.

Types of proof of income letters

A wide range of formats exist depending on the issuer. The generator above covers the most common types used internationally.

1. General proof of income letter

This version is used when a neutral institution, financial advisor, or organisation confirms income based on available evidence. It is suitable for most financial or administrative requests.

2. Salary confirmation letter from employer

The most widely used format. Employers confirm the individual’s position, salary, employment status, and regular payment schedule. This type is typically required for:

• bank loan applications;
• visas and embassy requirements;
• employment transfers;
• rental applications;
• financial background checks.

3. Proof of income for bank or KYC

Banks often require a specific format that references compliance, KYC, or the purpose of the letter. It must be unambiguous and include clear figures to satisfy regulatory requirements.

4. Self-declared income affidavit

This is a formal self-attested letter declaring the individual’s income when no other documents are available. It is accepted for:

• online registrations;
• platform KYC checks;
• informal agreements;
• internal HR processes;
• local administrative registrations.

Banks and embassies rarely accept self-declarations without additional documentation.

Proof of income vs salary confirmation vs income affidavit

These terms may overlap but have different meanings:

Proof of income

General confirmation of incoming funds — salary, business income, rental income, contract work payments, etc.

Salary confirmation

Confirmation specifically issued by an employer that details the individual’s official salary.

Income affidavit

A self-declared income statement, often used when formal documentation is not available.

Common validity requirements

Organisations often require letters to be recently issued:

• Banks — within 30 days;
• Embassies — 30–60 days;
• Landlords — 30–90 days;
• Government institutions — varies by jurisdiction.

Some institutions require the letter to be printed on official letterhead.

Common mistakes to avoid

• unclear income period (weekly / monthly / yearly);
• incorrect corporate details;
• missing issuer information;
• no date on the document;
• informal writing style;
• using outdated or unverified income numbers;
• missing signature (if required).

Supporting documents often requested in addition

Depending on the institution, additional documents may be necessary, such as:

• bank statements;
• payslips;
• employment contracts;
• tax returns;
• business registration documents;
• invoices or proof of freelance income;
