Filed Your Taxes Late? How It Affects Your Self-Employed Mortgage — and How to Recover

The offer is accepted and your deposit is in. Then your broker asks for your two most recent Notices of Assessment, and the room goes quiet, because the last return you filed was two years ago.

It happens constantly. Running a business and keeping your own paperwork current are two different jobs, and the second one loses. If you've filed your taxes late, it does affect your self-employed mortgage — but it's a delay far more often than a dead end. Here's what lenders check, why owing money is a bigger problem than simply being behind, and the order of steps that gets your file moving again.

Why a Late Filing Stalls a Self-Employed Mortgage

When you work for someone else, your income is easy to prove: a job letter, a couple of pay stubs, a T4. When you work for yourself, none of that exists. The Notice of Assessment becomes the proof, because it's the government confirming what you told them you earned.

Most banks and credit unions ask for the same short list: your two most recent Notices of Assessment, the matching returns, and a statement of account from the CRA showing nothing outstanding. Miss one year and the file has a hole in the middle of it. There's no way to average two years of income when one of them hasn't been assessed yet.

The second problem is timing, and it's the one that costs people houses. File electronically and the assessment usually shows in your CRA online account within a couple of weeks, sometimes days. File on paper and you're looking at eight weeks or more. On a 30-day close, that difference decides whether you fund on time.

There's also a deadline mix-up that catches a lot of business owners. If you're self-employed, your return isn't due until June 15 — but any money you owe was due April 30. People hear "June 15" and assume it covers both. It doesn't. Interest runs on the balance from May 1, whether or not the return is in.

Not Filing and Owing Money Are Two Different Problems

Lenders treat these very differently, so it's worth knowing which one you have.

Behind on filing, but you don't owe much. This is a paperwork gap, and it's the easier version. Get the returns in, get the assessments back, and the file can move. If you don't owe a balance, there's generally no late-filing penalty either — the penalty is calculated on what you owe.

Filed, but there's a balance sitting there. This one is heavier. That balance shows on your statement of account, and most banks and credit unions won't fund while it's there. Many alternative and private lenders also want tax arrears cleared, though a lot of them will let the balance be paid out of the mortgage proceeds at closing — which is how plenty of business owners clear a CRA debt and refinance in one move.

Two things make an unpaid balance worse the longer it sits:

• The penalty. Filing late generally costs 5% of the balance owing, plus 1% for every full month the return is late, up to 12 months. If you were charged the same penalty in any of the previous three years, it can climb to 10% plus 2% per month for up to 20 months. Arrears interest applies on top, set quarterly and sitting around 7% as of 2026. Filing stops the penalty clock even if you can't pay yet, which is why "I'll file when I can afford it" is the most expensive plan there is.
• A lien on title. The CRA can register against your property, and once that's on title it blocks a refinance or a sale until the debt is handled. If you're incorporated there's an extra wrinkle: payroll source deductions and GST/HST are treated as deemed trust money and can rank ahead of a lender's mortgage. That's why an incorporated owner with a CRA balance gets a closer look than a sole proprietor with the same number.

The Canada Revenue Agency sets out the current rules on its interest and penalties page. Figures change, so check there or ask your accountant rather than working off an old number.

Your Options for a Self-Employed Mortgage While You Catch Up

Here's the part most people don't know, and it's why a late filing usually isn't fatal. Not every lender in Canada reads your income the same way. There are three broad tiers, and only one of them lives and dies by your Notice of Assessment.

• A-lenders — the big banks, credit unions, and monoline lenders. They usually average your last two years of declared income from your Notices of Assessment, or use a business-for-self program where declared income is supported a different way, sometimes with a reasonable add-back on the business portion. Best pricing, debt ratios around 39% and 44%, and the federal stress test applies. They want recent, clean assessments, so this is the tier a missing year shuts down.
• B-lenders, or alternative lenders. Often they don't need your most recent Notice of Assessment at all. Many will take roughly the last twelve months of business bank statements to establish gross revenue, then qualify you on the business net income. They can also go below a 600 credit score depending on how the rest of the file looks, and can stretch debt ratios toward roughly 50% and 50%. In exchange they generally want more down, often around 20%, plus a lender fee. For someone mid-catch-up, this is frequently the actual answer.
• Private lenders, who lend on the equity in the property far more than on your paperwork. Expect 20% to 25% or more in down payment or equity, a short term of about a year, and fees. This is a bridge, not somewhere to live — you go in with a written plan to get your filings current and move to a better lender when they're done.

So "the bank said no because I haven't filed" and "I can't get a mortgage" are not the same sentence. We've written full guides to how B-lender and alternative mortgages work and to when a private mortgage lender makes sense. If your declared income is low because of write-offs rather than late filing, the piece on how stated income mortgages work covers that side of it.

How to Recover: the Order That Actually Works

Do these in sequence. People who jump to step four first tend to spend money in the wrong place.

1. Find out exactly where you stand. Log into CRA My Account and pull your statement of account. You need two facts: which years are unfiled, and what the balance is. Guessing is how people discover a lien three days before closing.
2. File everything, oldest year first — even if you can't pay a cent. The penalty is based on what you owe and stops growing the day the return goes in. Interest keeps running, but that's the smaller half.
3. File electronically. The assessment lands in your CRA account far faster than a paper return, and your lender can work from something you can actually see and print.
4. Deal with the balance. Pay it if you can. If you can't, call the CRA and set up a payment arrangement before they come to you — an arrangement in good standing reads much better than silence. Some lenders still want the balance at zero before funding, and clearing arrears out of mortgage proceeds is a normal structure your broker can look at.
5. Ask about relief if there was a real reason. If illness, a death in the family, or something else outside your control put you behind, the CRA can cancel or waive penalties and interest through the taxpayer relief process using Form RC4288. It reaches back roughly ten years and decisions generally take several months, so start early. The underlying tax still has to be paid.
6. Bring in your broker while this is happening, not after. Where your file should go depends on how many years are missing, how big the balance is, and what you have for a down payment. That conversation is free, and having it in week one usually shortens the whole timeline.

The Mistakes That Cost People the Deal

A few patterns show up over and over:

• Rushing a return just to produce an assessment, then amending it later. When your application says one number and your assessment says another, the file gets a much harder look.
• Writing off every possible dollar for years, then wanting a large mortgage. You can have low declared income or high borrowing power. Getting both takes planning with your accountant a year or two ahead.
• Waiting until the offer is accepted. Catching up on two years of returns takes weeks. Conditions don't.
• Not telling your broker. It comes out anyway, at the worst moment. Told early, it's a plan. Found late, it's a collapsed deal and a deposit at risk.

How Gold Lion Mortgages Can Help

Self-employed files are most of what we do, and nobody here is going to be shocked that you're behind. We've sat with contractors, truckers, restaurant owners, and consultants who were three years back and certain they'd never own a home. Most of them own one now.

What we do is look at your situation before anyone runs your credit, and tell you plainly which tier your file belongs in today. Sometimes the answer is to file two returns and wait six weeks for a better lender. Sometimes it's an alternative lender using your bank statements now, with a plan to move you once your filings are current. Sometimes it's clearing a CRA balance out of a refinance so the lien comes off title. We'll tell you which one it is and what it costs, including when the right advice is to wait.

Our self-employed mortgage page covers the programs available to business owners, and the full guide to getting approved when you're self-employed walks through the documents in more detail. We work with clients across Canada.

Call (587) 740-0048 or visit goldlionmortgages.com/apply. The first conversation is free and confidential, and it's worth having even if you're a year from buying.

Frequently Asked Questions

Can I get a mortgage if I haven't filed my taxes?

It depends which lender the file goes to. Most banks and credit unions want your two most recent Notices of Assessment plus a statement of account showing nothing owed, so an unfiled year usually stops that application. Alternative lenders can often use roughly twelve months of business bank statements instead, and private lenders look mainly at the equity in the property. Not filing narrows your options rather than ending them.

How long does it take to get a Notice of Assessment after filing late?

If you file electronically, it usually appears in your CRA online account within a couple of weeks, and often much sooner. A paper return typically takes about eight weeks or more, and longer during busy periods. If a closing date is involved, file electronically and watch your CRA account rather than waiting for mail.

What is the penalty for filing taxes late in Canada?

Generally 5% of the balance you owe, plus 1% for each full month the return is late, to a maximum of 12 months. If you were charged the same penalty in any of the previous three years, it can rise to 10% plus 2% per month for up to 20 months. Arrears interest applies on any unpaid balance and is set quarterly, around 7% as of 2026. If you owe nothing, there's generally no late-filing penalty — but a lender still needs the return filed.

Do I have to pay off my CRA balance before I can get a mortgage?

For most bank and credit union files, yes. Lenders normally ask for a statement of account showing no taxes owing before they fund. Some alternative and private lenders will let arrears be paid out of the mortgage proceeds at closing, which is a common way people clear a balance and refinance in one step. A payment arrangement in good standing helps with some lenders; others still want the balance at zero.

Can the CRA put a lien on my house for unpaid taxes?

Yes. The CRA can register a lien against your property, and once it's on title it can block a refinance or a sale until the debt is dealt with. Business amounts like payroll source deductions and GST/HST are treated as deemed trust funds and can rank ahead of a lender's mortgage, which is why incorporated owners with a CRA balance get a closer look. Handling it early is far easier than clearing a lien mid-transaction.
