Tax Assessment Notice
A tax assessment notice (also called a tax return transcript or tax summary) is the official document issued by a country's tax authority indicating the income declared by a taxpayer and the resulting tax liability. Every jurisdiction has its equivalent: IRS Tax Return Transcript or Form 1040 (US), HMRC Tax Calculation / SA302 (UK), avis d'imposition (France), Steuerbescheid (Germany), ATO Notice of Assessment (Australia), and CRA Notice of Assessment (Canada).
Tax assessment notices are among the most authoritative proof-of-income documents because they are issued directly by government tax authorities and cover all income sources. Their content and use vary by jurisdiction:
- **United States**: The IRS issues Tax Return Transcripts and provides Form 1040 summaries. Lenders commonly request these via IRS Form 4506-T (Request for Transcript of Tax Return). The transcript shows filing status, adjusted gross income (AGI), taxable income, and tax paid. - **United Kingdom**: HMRC issues the SA302 Tax Calculation for self-assessment filers, and the P60 summarizes employment income and tax paid for the year. The Tax Overview provides the amount owed or refunded. - **France**: The avis d'imposition is issued annually by the Direction Generale des Finances Publiques. It contains the reference taxable income (RFR), number of fiscal shares, income breakdown, and a tax reference number for online verification via impots.gouv.fr. - **Germany**: The Steuerbescheid, issued by the Finanzamt, details taxable income, allowable deductions, and the final tax assessment. It serves as the official record for loan applications and government procedures. - **Australia**: The ATO Notice of Assessment confirms taxable income, tax liability, and any refund or amount owing. It is commonly requested by lenders under responsible lending obligations. - **Canada**: The CRA Notice of Assessment summarizes the return as assessed, including total income, deductions, and the refund or balance owing.
In KYC and creditworthiness verification procedures, tax assessment notices are particularly reliable proof of income because they capture all taxpayer income — salaries, rental income, capital gains, dividends, and self-employment earnings. Banks, landlords, and credit institutions systematically require them, often alongside payslips, to assess an applicant's overall financial situation.
Document verification solutions like CheckFile.ai enable authentication of tax notices from multiple jurisdictions by automatically extracting key data (income figures, tax amounts, reference numbers) and detecting inconsistencies or forgeries. AI can verify mathematical consistency between declared income and calculated tax, and official reference numbers can be used for cross-verification with tax authority portals where available.
