Renewing with your current lender usually does not require you to prove your income again. Switching to a new lender does, and the new lender will typically qualify you on your two-year income average, not your best year. If that average has fallen since you last applied, staying put often protects you, while switching can pull your qualifying income down with it.

Does a Same-Lender Renewal Retest Your Self-Employed Income?
In most cases, no. A straight renewal with your existing lender, same balance and same amortization, is generally treated as a continuation of your existing mortgage rather than a brand new application. The lender already holds your file and is offering you a new rate and term, not re-underwriting you from scratch.
That means your current lender typically does not re-pull your Notices of Assessment, re-run your two-year average, or re-verify your declared income for a straight renewal. Some lenders reserve the right to ask for updated documents in specific cases, so this is not an absolute guarantee across every file. For a self-employed borrower whose income has softened, that is usually good news: the renewal itself is not the moment your income gets tested again.
A same-lender renewal typically does not require you to re-prove your self-employed income.
Why Switching Lenders Means Requalifying on Your Lower Average
Switching lenders is a new application from the new lender’s point of view. They will pull fresh Notices of Assessment, business financial statements, and bank statements, and they will run their own income calculation, usually built around a two-year average of your declared self-employed income.
Here is an illustrative example. Say your declared net self-employed income was $110,000 two years ago and $70,000 last year, the drop year.
A straight two-year average puts your qualifying income at $90,000, not your stronger $110,000 year and not your weaker $70,000 year. Some lenders instead qualify you on the lower of the two years, which in this illustrative case would mean qualifying on $70,000 alone. This is an illustrative example only, not a quote of what any specific lender will do with your file.
Switching lenders at renewal generally means requalifying on a two-year average of your declared income, which can be lower than the figure your current lender approved you on originally.
How Lenders Average Self-Employed Income (Method Varies by Lender)
There is no single formula every lender uses, and the method matters as much as the numbers. The table below lays out the common approaches, described directionally since exact policies vary by lender and can change.
| Approach | How It Generally Works | Effect on a Drop Year |
|---|---|---|
| Straight two-year average | Adds the two most recent years of declared income and divides by two | Softens the drop but still pulls the qualifying figure down |
| Lower of the two years | Some lenders qualify you on whichever year is lower, no averaging | Can push qualifying income all the way down to the drop-year figure |
| Weighted toward the most recent year | Gives more weight to the latest tax year than the prior one | Can land close to the drop-year figure |
| With add-backs applied | Adds certain non-cash or one-time deductions back to declared income before averaging | Can partly offset the drop, where the lender offers add-backs at all |
No dollar thresholds or percentages above are guaranteed; a broker who knows which lenders use which method can steer you toward the one that treats your specific file best.
When Staying With Your Current Lender Is the Right Move
Staying is usually the safer path when your income drop is recent and your business is stable or recovering. Because a straight renewal typically skips the income test, you keep the mortgage you already qualified for without your lower year ever entering the conversation.
This matters most if the drop was tied to a one-off event, a slow year, reinvestment in the business, or a temporary contract gap. It also matters if your two-year average would not clear a new lender’s bar at all. Renewing does not mean you cannot still negotiate; you can push your current lender on rate even while skipping requalification.
If your recent income drop makes a new lender’s math harder, a same-lender renewal is often the lower-risk choice.
When Switching Still Makes Sense Despite the Lower Average
Switching can still be worth it in a few specific situations. If your current lender’s renewal offer sits well above market and you can still clear a new lender’s bar even on the lower average, the rate saving may outweigh the paperwork. If the drop year is about to roll off your two-year window because a new tax year is coming, waiting a few months before switching can restore a stronger average.
If you already need to add money or extend your amortization for another reason, you will face full requalification whether you stay or switch, so the stay-versus-switch decision changes. In that case, comparing lenders becomes worthwhile since you are requalifying regardless. Our guide to switching lenders at renewal covers the mechanics of a straight switch in more detail.
When a B-Lender Bridge Makes Sense
A B-lender bridge is worth considering when your two-year average is too low for any A-lender switch but you need to move away from your current lender anyway. B-lenders weigh actual business cash flow, bank deposits, and recent activity more heavily than a strict two-year average of declared income. They charge a higher rate and often a broker fee in exchange for that flexibility.
The usual play is to bridge with a B-lender for a year or two while your declared income recovers, then refinance to an A-lender once your file is stronger. This mirrors the approach we lay out in our guide to self-employed borrowers with low declared income, which goes deeper on add-backs, stated-income programmes, and the B-to-A bridge. Our broader self-employed mortgage guide is a good starting point if you are new to how self-employed income gets assessed at all.
Stay or Switch: A Quick Decision Table
| Your Situation | Likely Better Move | Why |
|---|---|---|
| Income dropped in the last year only, business is stable or recovering | Stay and renew with your current lender | A straight renewal typically does not retest income |
| Current lender’s offer is well above market and you can still qualify on the lower average | Shop the switch | The rate saving can outweigh the requalification effort |
| Two-year average is too low for any A-lender to approve | Renew with your current lender, or consider a B-lender bridge if you must move | Preserves financing without forcing a decline |
| You need to add money or extend amortization regardless | Expect full requalification either way | New borrowing triggers a full application whether you stay or switch |
How to Prepare, Whichever Way You Lean
Start gathering documents well before your maturity date, even if you plan to stay. You will want two years of Notices of Assessment, two years of business financial statements, and recent personal and business bank statements ready, since a change of plan late in the process costs you time.

Frequently Asked Questions
Does renewing with my current lender require new proof of income if I’m self-employed?
Generally no, for a straight renewal with the same balance and amortization. Your current lender is typically offering a new rate and term on the mortgage it already holds, not re-underwriting the file. Some lenders may still request updated documents in specific circumstances, so confirm directly if you are unsure.
Will a new lender use my most recent year’s income or my average when I switch?
Most lenders build your qualifying income around a two-year average of your declared self-employed income, though the exact method varies. Some average the two years, some use the lower of the two, and some weight the recent year more heavily. Ask any lender you are considering which method they apply before you commit to a switch.
Can I still switch lenders if a B-lender is my only option?
Yes. A B-lender assesses actual business cash flow rather than relying solely on a two-year average of declared income, which can make a switch possible when an A-lender says no. Many self-employed borrowers use a B-lender as a bridge for a year or two and refinance to an A-lender once their income recovers.
Should I fix my income drop before I try to switch?
If the drop is recent and your two-year average has not yet recovered, waiting even one tax year can meaningfully change your qualifying number once the drop year is replaced by a stronger one. In the meantime, a same-lender renewal usually lets you avoid the income test altogether. Talk to a broker about the timing before you approach a new lender.
Does switching lenders at renewal still mean skipping the stress test?
The stress test question is separate from income averaging. A straight switch of an uninsured mortgage, same balance and amortization, has not required the stress test since a 2024 OSFI change, but the new lender still verifies your income and credit. Read our guide on switching lenders at renewal for the full mechanics.
Renewing Self-Employed? Get the Numbers Right Before You Commit
A dropped income year does not have to force your hand at renewal. Knowing whether your lender’s renewal skips the income test, and how a new lender would actually average your numbers, is what decides whether staying or switching is the smarter move.
Work through the stay-or-switch math with a broker before your maturity date, not after you have already applied somewhere new.
