If you've calculated your taxes and know that you can't currently pay your balance owing, you should still file your tax return by the annual deadline to avoid the late-filing penalty.
After we've processed your return, we'll send you a Notice of Assessment. If your Notice shows a balance owing that you can't pay, you should arrange a mutually acceptable payment schedule by calling our toll-free number at 1-888-863-8657, Monday through Friday from 8:00 a.m. to 5:00 p.m. local time.
Any outstanding balance is subject to daily compound interest, starting on the annual filing deadline and continuing until you've paid the amount in full.
