You just realized you should have filed an NR6 but didn't. Maybe you didn't know about it. Maybe your accountant never mentioned it. Whatever the reason, you're now wondering: How bad is this?
First: Don't Panic
Missing the NR6 deadline isn't the end of the world. There are no direct "late filing penalties" for NR6 itself. But there are significant financial consequences you need to understand.
What is the NR6 Deadline?
Let's be clear about what "deadline" actually means for NR6:
NR6 Timing Rules
- 1
For existing properties:
File by December 31 for the NR6 to be effective January 1 of the next year
- 2
For new properties:
File before your first rental payment
- 3
Processing time:
CRA takes 4-8 weeks to approve, so factor that in
The key point: NR6 only applies going forward from when it's approved. It's not retroactive.
Can NR6 Be Filed Retroactively?
No. This is the most important thing to understand. NR6 cannot be backdated. If you file NR6 in March, it only applies from March onward (once approved). January and February withholding is still at 25% of gross.
Real Example:
John forgot to file NR6 for 2026. He realizes in April and files immediately. His NR6 is approved in May. For January-April, his property manager withheld 25% of gross rent ($2,500/month × 4 months = $10,000 withheld). With NR6, it would have been $1,000/month ($4,000 total). John overpaid $6,000 for those 4 months. He can get it back via Section 216, but not until 2027.
How to Minimize Damage If You Already Missed It
If you're reading this and haven't filed NR6 yet:
- 1
File NR6 immediately
Every day you wait is another day of 25% gross withholding.
- 2
Track your expenses carefully
You'll need them for your Section 216 return to claim a refund.
- 3
Set a reminder for next year
File by December 31 for the following year. Don't let this happen again.
- 4
File Section 216 on time
Due June 30 of the following year. This is how you get your overpaid tax back.
The Bottom Line
There's no specific "NR6 late filing penalty" from CRA. But the consequence of not filing—or filing late—is that you overpay tax and have to wait 12+ months to get it back.
