Notice of Assessment (NOA)

Definition

A Notice of Assessment (NOA) is the Canada Revenue Agency’s summary of a filed tax return, showing reported income and any balance owing, and it is one of the standard documents Canadian lenders request to verify a borrower’s qualifying income.

Why do lenders ask for the NOA specifically?

A pay stub or offer letter shows what an employer says a borrower earns; the NOA shows what the borrower actually reported to the CRA and whether the CRA agreed with it. For self-employed borrowers and anyone with variable or commission income, lenders typically want two or more years of NOAs alongside T1 Generals to establish a reliable average.

Lenders also check the NOA for a balance owing. An outstanding tax debt can affect approval because it represents an undisclosed liability and, in some cases, a potential lien position ahead of the mortgage. Borrowers who file late or amend a return should expect lenders to ask for the most current NOA available.

How it’s used in Canada

Self-employed files: brokers commonly request two to three years of NOAs plus T1 Generals to document income that isn’t a fixed salary.

Paired with employment documents: salaried borrowers are typically asked for an NOA alongside a letter of employment or recent pay stubs, not one or the other.

Available through CRA My Account: borrowers can retrieve current and prior-year NOAs directly from the CRA rather than relying only on a mailed copy.

Privacy handling: NOAs contain sensitive personal and financial information, so brokers and lenders handle and store them under PIPEDA obligations.
