Is this you?
- I worked multiple jobs
- Each job withheld tax
- I owe tax unexpectedly
"Payroll withholding always covers my tax."
Each employer applies the Basic Personal Amount (about $16,452 for 2026), but you only get it once on your return.
Why guessing is risky
- Under-withholding appears at filing
- Repeats annually if unchanged
- Interest applies if unpaid
Safe to ignore if
- I had only one employer
- Extra tax was withheld
Stop and check if
- I had multiple T4s
- I owed tax unexpectedly
