Qualification•By Ratellow Research Team•Verified 2026-09-01•How we research

How does variable income — bonuses, commissions, overtime — affect my mortgage qualification?

Lenders typically use a 2-year average of variable income components (bonuses, commissions, overtime) from your T4s and NOAs. The key is demonstrating consistency — a one-time bonus doesn't help much, but 2 years of regular commissions usually qualifies at 80-100% of the average.

Variable income can count toward your qualification, but lenders apply a stability test before including it — the less predictable the income, the more documentation you need.

How Lenders Treat Each Type

Commissions (sales roles)

  • A-lenders: Use 2-year average of gross commissions from T4s. If you've been in the role less than 2 years, approval is challenging at A-lenders.
  • Gross vs net: Lenders use the T4 gross amount, not net after business expenses.
  • Declining commissions: If year 2 is lower than year 1, some lenders use only the lower year.

Bonuses

  • 2-year average: Used if the bonus is recurring and documented on T4s for both years.
  • One-time bonus: Typically excluded entirely.
  • Guaranteed bonus: If an employment letter confirms a guaranteed annual bonus amount, it may be included at 100%.

Overtime

  • Same 2-year T4 average rule. If overtime is mandatory and documented as part of the role (e.g., union contract), it's more likely to be included in full.

Part-Time Employment

  • Included in full if you've held the part-time role for 2+ years alongside primary employment.

Tips to Strengthen Your Application

  • Provide a 3-year average if years 1-2 show increasing income — it tells a better story.
  • Employment letter: Ask your employer to confirm the variable income is recurring and expected to continue.
  • Pay stubs: 90 days of pay stubs showing recurring variable component strengthen the case.

Your Next Steps

  1. Gather your last 2 years of T4s and NOAs before applying
  2. Request an employment letter confirming your expected variable income
  3. Speak with a mortgage advisor to determine which lenders are most favorable for your income profile
