What is Claiming OTB Retroactively for Past Years?
A surprising number of Ontario filers miss OTB because they file their return but never complete ON-BEN. That often means the sales-tax piece is automatic, but the larger housing components are missed.
Do I Qualify?
- You must have been eligible in the original year
- The missing issue is often paperwork, not lack of eligibility
- Retroactive correction windows are limited by tax adjustment rules
- Good records for rent or property tax improve the adjustment process
How Much Can I Get?
Missed OTB can add up significantly across multiple years, especially if the larger OEPTC housing component should have been paid.
How to Apply
Request a T1 adjustment for the affected year and make sure the missing OTB/ON-BEN information is properly supplied for that year.

What is a T1 Adjustment?
It is a request to change a tax return that was already filed and assessed so CRA can recalculate the result.
How far back can I claim?
The adjustment window is limited, but many taxpayers can still correct several past years if they act soon enough.
Why is my Canada PRO deposit so small?
Often because only the automatic sales-tax component was paid, while the housing component was missed due to incomplete ON-BEN information.
