If you run a business or side hustle in Canada, Australia, New Zealand, the UK, or anywhere else that uses a value-added or goods-and-services tax, every receipt you collect carries a small piece of your next tax return. HST, GST, and their provincial cousins add up to a real number on your quarterly or annual filing, and the Canada Revenue Agency, HMRC, and the ATO will all ask the same question if you are audited: can you show what you paid, when you paid it, and how much tax was charged?
Tracking receipts for HST and GST is not glamorous work, but it is the kind of task that pays for itself the first time you file cleanly. The goal is a paper trail you can hand to your accountant (or the tax office) without spending a weekend sorting shoeboxes. This guide walks through the practical steps a freelancer, bookkeeper, or small business owner can follow to keep a clean, audit-ready record of every tax-bearing receipt.
What you need
Before you start a tracking workflow, gather the basics:
- A consistent place to capture receipts. A single folder on your phone, a cloud drive, or a dedicated app. Pick one and stick with it; the value of the system comes from using it every time.
- A way to read the tax line. Most modern receipts break out HST or GST as a separate line item, and you need to capture that number, not just the total.
- A destination for the data. Spreadsheet, accounting software, or your bookkeeper's inbox. The export format should match where your numbers already live.
- A retention policy. Six years for CRA, five years for HMRC, five years for the ATO. Keep digital copies in case the paper fades.
Phase 1: Capture every receipt the day you get it
The single biggest cause of missing input tax credits is the receipt that lives in a wallet, glove box, or laptop bag for three months before someone remembers to deal with it. Capture on the day, even if you do not process it until later.
Two practical habits help:
- Photograph paper receipts the moment you set them down. Hold the phone flat, make sure the merchant name, date, total, and tax line are all legible, and save the image to a dedicated folder. Receipt paper fades fast, especially the thermal kind used at gas stations and coffee shops.
- Forward digital receipts to one inbox. If a vendor emails you a PDF or e-receipt, send it to a single address or cloud folder as soon as it arrives. Out of sight is out of mind, and "I'll file it later" is where the tax credit goes to die.
Phase 2: Extract the fields that matter
Once a receipt is captured, you need the numbers out of the image and into a structured record. At minimum, capture:
- Merchant name (who you paid)
- Date of purchase (when you paid)
- Subtotal (before tax)
- HST or GST amount (the recoverable tax)
- Total (what left your account)
- Tax rate or breakdown (some provinces have multiple rates on one receipt)
- Category (office supplies, travel, software, meals, etc.)
This is where most people give up. Typing seven fields for thirty receipts a week is tedious, which is why so many small businesses end up with a year-end stack of unsorted paper. SlipSheet reads the QR code or OCR text on a receipt and pulls merchant, date, subtotal, tax, and total into a spreadsheet in under three seconds. You review the fields, correct anything that is off, and move on.
Phase 3: Review and reconcile weekly
Daily capture plus weekly review is the rhythm that actually works. Block 20 to 30 minutes on Friday afternoon or Sunday evening and:
- Open the week's captured receipts.
- Confirm each tax line was read correctly. GST and HST rates vary by province and territory in Canada (5% GST federally, plus 7% to 10% provincial), so do not trust a single rate.
- Tag the category so your accountant does not have to.
- Flag anything ambiguous for follow-up. A receipt with no tax line might be a tax-exempt purchase, an out-of-country vendor, or a missed line item. Do not guess; check.
Weekly review catches problems while the receipt is still fresh. Trying to reconcile 200 receipts in April for a March 31 year-end is how people end up paying tax on expenses they actually paid.
Phase 4: Export and hand off
At month-end or quarter-end, export your reviewed data to wherever the rest of your books live. CSV is the universal format and opens in Excel, Google Sheets, QuickBooks, Xero, Sage, and Wave. If you work with a bookkeeper, send the export rather than the raw scans; they will thank you.
Keep both the structured data and the source image together. If the CRA asks for proof of an input tax credit, you want the PDF or photo on file, not just a number in a spreadsheet. A typical SlipSheet export keeps the line items and a link back to the original receipt image so the audit trail stays intact.
Common mistakes to avoid
- Tracking only the total, not the tax. The CRA and ATO both want the recoverable tax broken out. A $112.98 lunch receipt might include $7.02 of HST, and that $7.02 is what lowers your tax bill.
- Mixing business and personal expenses in the same pile. If you buy a personal item on the same trip as a business purchase, log them separately from the start. Combining them creates a paper-trail mess that is hard to untangle later.
- Throwing out the paper too soon. Digital copies are great, but the CRA's standard is six years from the end of the tax year in which the expense was claimed. Keep the original or a clear scan for the full retention period.
- Forgetting the small stuff. Software subscriptions, domain renewals, parking, and bank fees all carry HST or GST and all count toward your input tax credits. A $9 monthly SaaS charge is only $108 a year, but that is also $13 of recoverable HST you should not be paying tax on.
Getting started
Set up your system this week, not next quarter. Pick a capture spot, choose a tool to extract the numbers, and decide where the export lands. The first month will feel like overhead; by month three, you will have a clean, queryable record of every tax-bearing purchase and a filing process that takes an afternoon instead of a week. When the tax notice arrives, you will be ready.
If you want a head start, SlipSheet reads HST and GST receipts, exports to CSV or Google Sheets, and keeps the source image linked to each line item. Start a 14-day trial and run your last month of receipts through it; you will see exactly how much recoverable tax you have been leaving on the table.
FAQ
Do I need to track HST and GST separately if I am registered for both?
Yes. Even though HST includes the federal GST portion, the CRA reports them on different lines of your return. Capture the full tax amount on the receipt and note the rate; your bookkeeping tool should split the federal and provincial components.
How long do I need to keep HST and GST receipts?
Six years from the end of the tax year in which you claimed the input tax credit in Canada, five years in the UK for HMRC, and five years in Australia for the ATO. Digital copies are accepted as long as they are legible and tied to the original transaction.
What if a receipt does not show a tax line?
It could be tax-exempt, an out-of-country vendor, or a missed line item. Do not guess; ask the vendor for an itemized receipt or check whether the product category is zero-rated in your province. Logging a zero-tax entry is better than skipping the receipt entirely.
Can I claim HST or GST on small recurring expenses like software subscriptions?
Yes. Any business expense that includes recoverable tax counts, regardless of size. A $9 monthly SaaS charge carries HST or GST that adds up over a year, and the CRA, HMRC, and ATO all allow input tax credits on legitimate business purchases.
What is the fastest way to capture a stack of paper receipts?
Photograph each one with your phone the day you receive it, save to a single folder, and run the images through an OCR or QR reader like SlipSheet to pull merchant, date, subtotal, tax, and total into a spreadsheet. Review weekly, export monthly.
