Compare obligations with the possible benefit

Voluntary registration can create a different customer-pricing and recordkeeping position. Review who your clients are, what you sell and the kinds of costs you incur. A potential input tax credit is only one part of the decision. Consider the practical work of invoicing, collecting, reporting and paying the tax under the applicable rules.

Choose the timing with complete records

Before registering, organize recent purchases, contracts and projected activity for review. Do not assume every earlier tax payment becomes recoverable when the account opens. Ask which effective date and opening information apply to the circumstances. Once registered, keep filing deadlines and invoice treatment aligned rather than waiting until the annual income-tax return to address the account.

What to gather before the review

• Description of taxable and other supplies
• Customer mix and expected business activity
• Recent purchases and proposed registration timing

Is voluntary registration always a tax-saving move?

No. The effects depend on the business, customers, costs and obligations. Compare the full position before registering, and distinguish voluntary registration from a situation where registration is already mandatory.

Your next step

Prepare expected sales and costs and identify whether customers can recover the tax you would charge.
