Ottawa's business base skews toward technology, government contracting and professional services. The corporate-tax risks here are less about inventory and more about missed elections and avoidable penalties. This post is about the penalties Ottawa corporations most often walk into, and how to sidestep them.
The late-filing penalty
File your T2 late with a balance owing and the CRA charges 5% of the unpaid tax plus 1% for each month late, up to 12 months. A second late filing within three years doubles that to 10% plus 2% per month. On a mid-sized balance this escalates fast, and it is entirely avoidable by filing on time even if you cannot pay in full.
Instalment interest
A corporation that owed more than $3,000 in tax last year is generally required to pay tax by monthly instalments. Miss them and the CRA charges instalment interest, and where that interest is large enough, an additional instalment penalty on top. Many profitable Ottawa consultancies get caught here in their second year, having paid nothing in instalments during a strong first year.
SR&ED: the election Ottawa tech firms miss
Ottawa's software and hardware companies frequently perform work that qualifies for Scientific Research and Experimental Development credits, but the claim has a hard filing deadline of 12 months after the T2 due date. Miss it and the credit is gone; there is no relief. Documenting eligible work contemporaneously, not reconstructing it a year later, is what makes a claim survive CRA review.
Payroll remittance timing
Corporations that pay salaries must remit source deductions on a schedule tied to their remittance size. Late remittances draw penalties of up to 10%, rising for repeat lateness. Government contractors scaling up their headcount often outgrow their remittance frequency without realising the deadline moved.
The common thread
Every penalty above is a deadline problem, not a tax-rate problem. An accountant who tracks your filing, instalment, SR&ED and remittance dates as a calendar, rather than reacting at year-end, eliminates the entire category of cost. For Ottawa corporations, that vigilance is worth more than any single deduction.
