HST Collected vs ITCs: A Simple Ontario Example (So Your Return Makes Sense)

If your HST return feels like “random math,” it's usually because one concept isn't clear: HST collected and Input Tax Credits (ITCs) are two different buckets, and your return is basically the difference between them.

This post gives a simple Ontario example of HST collected vs ITCs so your HST return actually makes sense—and your bookkeeping stays clean.

Quick Answer

HST collected is the tax you charge customers. ITCs are the HST you paid on business expenses (with proper receipts). Your HST return is usually: HST collected minus ITCs (plus/minus adjustments).

The simplest way to think about it

Bucket #1: HST you collected (from customers)

This is tax you charged on your invoices/sales.

Bucket #2: ITCs (HST you paid on business expenses)

This is tax you paid to vendors/suppliers that you may be able to claim back—if you have proper invoices/receipts.

Your return is the “net” of these buckets.

A simple Ontario example (numbers)

Let's say in one reporting period:

Sales (you charged customers)

• You billed customers: $10,000 + HST
• HST collected (13%): $1,300

So your HST collected = $1,300

Expenses (you paid vendors)

You had business expenses like supplies, software, fuel, etc.:

• Expenses: $3,000 + HST
• HST paid (13%): $390

If those expenses are eligible and documented, your ITCs = $390

Net tax (what you remit)

In this simple example, you'd remit $910 for that period (before any special adjustments).

What you must track so this works in real life

1) Clean sales records (HST collected)

• invoices issued
• deposits received (if applicable)
• which sales are taxable vs zero-rated/exempt (where applicable)

2) CRA-ready receipts for ITCs

To support ITCs, keep invoices/receipts that show:

• vendor name
• date
• description
• subtotal + HST amount (or tax-included clearly stated)
• total paid

3) Reconcile to bookkeeping before filing

If your HST return doesn't match your bookkeeping, CRA questions become more likely. A quick monthly reconciliation prevents most problems.

Common mistakes with “HST collected vs ITCs”

• Claiming ITCs with no valid invoice/receipt
• Mixing personal + business expenses and claiming 100%
• Using the wrong reporting period dates
• Filing from bank totals instead of proper bookkeeping categories
