Key takeaways
- →A promotion's new salary can generally be used once it's documented in writing and reflected on at least one pay stub — there's usually no need to blend it with the lower historical rate.
- →A promotion within the same employer reads as materially lower risk than a promotion tied to changing jobs, because the employment relationship itself hasn't changed.
- →Any variable component — bonus or commission — added as part of the promotion is treated separately, under the more conservative averaging rules that apply to variable income generally.
- →What matters to underwriting is documented, guaranteed, ongoing pay — a straight raise with no title change is functionally identical to a promotion in this sense.
A borrower who was bumped from analyst to senior analyst three months ago, with a documented salary increase, is in an unusual spot: their most recent tax return doesn't reflect their current reality, and their current pay stub doesn't have two years of history behind it. Getting this file right means understanding which of the two numbers the underwriter should actually be using.
Here's how promotions and raises get read, what changes when the promotion comes with a job change instead of an internal move, and how to document the new rate so it holds up.
01 · Why does a recent promotion create tension in a mortgage file?
The two most trusted documents in a standard file — the prior year's T4 and Notice of Assessment — both reflect income the borrower no longer earns. The document that reflects reality, a recent pay stub at the new rate, doesn't have the built-in verification history a full tax year carries. Reconciling those two facts is the entire job here.
02 · Does it matter whether the promotion happened with the same employer?
Yes, meaningfully. An internal promotion means the employment relationship, tenure, and track record with that employer all carry forward intact — only the compensation and title changed. A promotion that came with a new employer is closer to a standard new-job file, and should be documented and reviewed as one, distinct from a simple internal pay increase.
03 · What documents establish the new salary as real and ongoing?
A promotion or raise letter on company letterhead, stating the new base salary and its effective date, is the anchor document. Pair it with the most recent pay stub reflecting the new rate, and an updated employment verification if the lender requires one. Where the promotion also added a bonus or commission component, document that piece separately — it doesn't get the same immediate treatment as the guaranteed base.
04 · Do underwriters average the old and new salary, or use the current rate alone?
As a general practice, once the new guaranteed base salary is properly documented in writing and confirmed on at least one pay stub at that rate, it can typically be used on its own — there's no need to blend it down with the lower historical figure. Any variable pay layered on top of the promotion is a different story: bonus and commission income generally still needs an income history to be relied on, following the same conservative logic applied to variable income elsewhere on the file.
Recent change, current capacity
Don't let a raise read as a red flag.
Treadstone's fulfillment associates document income changes — promotions, raises, job moves — so the underwriter sees the real, current picture on the first pass. Talk to us about your next file.
05 · Is a straight raise, with no title change, treated any differently than a promotion?
Not meaningfully. What matters to the underwriting decision is documented, guaranteed, ongoing pay — not the HR label attached to how the employee got there. A raise letter carries the same weight as a promotion letter, provided it states the same key details: new rate, effective date, and confirmation the change is permanent.
06 · How should a broker package a recent-promotion file?
Include the promotion or raise letter and the current pay stub together, and flag the change proactively in a short cover note rather than letting it surface as an unexplained mismatch between the T4 and the pay stub during verification. A file that explains itself moves faster than one that makes the underwriter ask why the numbers don't match.
