31. What must an invoice show before I claim a GST/HST input tax credit?
You need sufficient documentary support, and the required details increase with the invoice amount. Supplier identification, transaction details and the applicable GST/HST information matter; at specified thresholds the registration number and purchaser details are required. A credit-card statement alone may not supply them. Verify the supplier’s registration where appropriate before claiming tax that was charged.
First step: Ask for a complete invoice and keep it linked to the payment in your records.

32. Can I deduct HST as an expense and also claim it back?
Do not count the same tax twice. When you claim an input tax credit for GST/HST paid or payable on an expense, reduce the income-tax expense by the credit. Tax that is not recoverable may form part of the expense or asset cost under the applicable rules. Reconcile the tax accounts before giving your preparer a total of business costs.
First step: Identify whether your expense summary is before or after recoverable GST/HST.

33. Are zero-rated and exempt sales the same?
No. Both can result in no GST/HST being charged to the customer, but they are different categories. Zero-rated supplies are taxable at 0%; exempt supplies generally do not support input tax credits for related purchases. Classification affects more than the invoice. A business with a mixture of supplies may need to allocate expenses and recoverable tax.
First step: List each service or product you sell instead of treating every receipt as one tax category.

34. Are all services provided by a healthcare professional GST/HST-exempt?
No blanket exemption follows from a job title. Many qualifying health services are exempt, but the specific service, provider and legal conditions matter. A practice may also sell taxable products or provide services outside an exemption. Separate those activities before deciding what to charge or which input tax credits can be claimed.
First step: Bring a description of each service, your relevant professional status and sample invoices for classification.

35. Do I charge GST/HST when my customer is outside Canada?
A foreign address does not automatically make a service zero-rated. Export rules depend on the supply, recipient and applicable exclusions. Services connected with Canadian property or provided in particular circumstances can be treated differently. Check the transaction before changing all foreign-customer invoices to 0%. Income-tax reporting of the revenue is a separate obligation.
First step: Keep the contract, customer residency information and details of where and how the service is supplied.

36. Do I still file GST/HST returns during a quiet period?
Yes. A registered business must file for every reporting period, including periods with no activity or no net tax to remit. A nil return is still a return. If the business has closed, the account must be dealt with properly and a final return may be required; simply stopping sales does not close the account.
First step: Check the reporting periods in your CRA business account and list every outstanding return.

37. Should I register for GST/HST voluntarily before I am required to?
It can be worth reviewing if you make commercial supplies and have eligible tax on purchases, but registration also brings collection, filing and recordkeeping obligations. Eligible input tax credits are only one part of the decision. Customer pricing, exemptions, startup costs and continuing compliance all matter. Voluntary registration should be a considered choice, not an assumption that every purchase produces a refund.
First step: Prepare expected sales and costs and identify whether customers can recover the tax you would charge.

38. How long should I keep receipts after filing?
The general CRA rule is six years from the end of the last tax year to which the records relate. Some records need to be retained longer, including information with continuing relevance to assets, losses or unresolved matters. Filing electronically does not mean receipts can be discarded. Keep readable records and reliable backups, and check the special rules before destroying older files.
First step: Separate permanent ownership records from annual receipts and note any open review or objection.

39. Are bank statements enough if I lost the receipts?
Bank statements show payments but may not explain what was purchased or its business purpose. CRA requires records supporting income and expense claims. Try to obtain duplicate invoices and reconstruct the supporting trail honestly; never create a receipt that pretends to come from a supplier. Missing evidence can affect a deduction or input tax credit.
First step: List each missing document and contact the supplier before the return is prepared.

40. Can I claim expenses paid in cash?
Cash payment is not itself a reason to reject a genuine eligible business cost, but it does not relax the recordkeeping requirement. Keep an invoice or receipt, supplier details, the date, purpose and evidence of payment. A cash withdrawal from your bank is not proof that the entire amount was spent on the business.
First step: Record cash transactions when they occur and reconcile them to receipts rather than using one unexplained year-end total.
Official guidance: Business records
General information, not an individual tax or legal opinion. Eligibility, elections and deadlines depend on the facts and tax year. Annual CRA forms may describe a specific year; use the form and limits for your return. No particular deduction, refund or tax saving is guaranteed.
