The problem
A lump-sum settlement is not periodic support, and the two are taxed differently under the Income Tax Act: periodic spousal support is taxable to the recipient and deductible to the payor, while a one-time lump-sum settlement is generally neither. Getting this file right meant treating both sides of that distinction correctly -- what the lump sum funds, and what it does not.
What the lump sum is, and is not
- ▸It is capital -- a one-time settlement she can put toward a down payment, exactly as she planned
- ▸It is not qualifying INCOME -- there is no monthly amount to add to her application the way periodic support would provide
- ▸Her ex-spouse's own separate mortgage application correctly gets no debt-service deduction for it either, since a lump sum was never a recurring payment to begin with
A broker unfamiliar with the distinction could have made either mistake: inflating her qualifying income with a support figure that doesn't exist month to month, or letting her ex-spouse's file claim a deduction for a payment that already happened once and is now finished.
The numbers
Once the lump sum was correctly kept out of the income side of the calculation, the purchase math is a straightforward insured file on her employment income alone.
| Qualifying on income alone, with the lump sum as capital only | Amount |
|---|---|
| Purchase price | $475,000 |
| Down payment (from the lump sum, 17.9%) | $85,000 |
| Base mortgage | $390,000 |
| CMHC premium — 2.80% at 80.01-85% LTV | +$10,920 |
| Total insured mortgage | $400,920 |
| Qualifying on her income | Figure |
|---|---|
| Minimum qualifying rate on a 4.65% contract rate | 6.65% |
| Qualifying payment, 25 years | $2,722/mo |
| GDS / TDS on $8,600/mo income | 36.3% / 39.1% |
Both ratios sit inside CMHC's 39% GDS and 44% TDS maximums on her $8,600/mo income alone -- the $85,000 lump sum appears only on the down-payment side of the file, exactly where it belongs, and nowhere on the income side.
The solution
A mortgage agent treated the lump sum's tax character as the first thing to confirm, before doing anything else with the file.
First, documented the separation agreement's own characterization of the payment as a one-time settlement rather than periodic support, confirming it wasn't structured as disguised monthly payments.
Second, sourced the full $85,000 down payment directly to the settlement funds, with a clear paper trail from the separation agreement to the funds actually being used.
Third, qualified the file on her employment income alone, deliberately not adding any support income to the application, since there was no recurring support payment to add.
The outcome
The purchase funded on her $8,600/mo income alone, GDS 36.3% and TDS 39.1%, both inside CMHC's maximums, and Ontario's land transfer tax on the $475,000 purchase came to $5,975.
This file addressed only her own purchase; her ex-spouse's separate mortgage application on his own file correctly claimed no debt-service deduction for a payment that was never recurring.
What to take from this file
- 01A lump-sum support settlement is capital, not income. It correctly funds a down payment without inflating what the recipient can qualify to borrow.
- 02Periodic and lump-sum support are taxed differently, and qualify differently as a result. Only the recurring kind belongs on the income side of an application.
- 03The payor gets no debt-service deduction for a lump sum. A deduction only ever applied to an ongoing, recurring obligation, and a one-time settlement isn't one.
- 04Confirm the separation agreement's own characterization of the payment. Whether it's genuinely a lump sum, not disguised periodic payments, decides which treatment applies.
- 05Trace settlement funds with a clear paper trail. A down payment sourced to a lump-sum settlement should be as well-documented as any other source of funds.
