When do I need to register for HST?

You must register for HST if your worldwide taxable supplies (revenue) exceed $30,000 over four consecutive calendar quarters or in a single quarter. You can also voluntarily register before reaching this threshold to claim ITCs on startup expenses.

What's the quick method for HST?

The quick method is a simplified way to calculate your HST remittance. Instead of tracking ITCs, you remit a fixed percentage of your revenue (usually 8.8% for service businesses in Ontario). It's often beneficial for service businesses with few input expenses.

How often do I need to file HST?

Filing frequency depends on your annual revenue: under $1.5M files annually, $1.5M-$6M files quarterly, and over $6M files monthly. CRA may also assign a different frequency based on your history.

What are Input Tax Credits (ITCs)?

ITCs are the HST you paid on business expenses that you can claim back against the HST you collected. Proper ITC tracking can significantly reduce your HST remittance or generate a refund.

What happens if I file HST late?

CRA charges a penalty of 1% of the balance owing, plus 0.25% for each month late (up to 12 months). Interest also accrues daily. We help you stay on schedule and avoid these costly penalties.

“Just had my personal income tax return filed and the entire experience was seamless. I'm based in Toronto and couldn't make it into their Oakville office, but they handled everything 100% virtually: collected my documents online, walked me through every deduction I qualified for, and filed my T1 return with the CRA quickly and accurately. Communication was fast, the pricing was fair, and I filed a T4A for the first time with no headaches. If you're in Oakville (or anywhere in the GTA) looking for a knowledgeable personal tax accountant who actually responds and gets the job done right, I'd highly recommend them.”
