GST/HST Registration Requirements in Canada: Who Must Register & Key Rules 🚀💼

Understanding GST/HST registration is critical for tax preparers, business owners, and anyone advising entrepreneurs in Canada. This guide breaks down who needs to register, how registration works, and important distinctions between business types — in simple language ✅

🧾 Who Must Register for GST/HST?

In Canada, most businesses must register for the GST/HST unless they qualify as a Small Supplier or only provide exempt supplies.

Category	Registration Requirement
Business providing taxable goods/services	✅ Must register
Small Supplier (under threshold)	❌ Not required, but can choose to register
Business providing only exempt supplies	❌ Do NOT register
Corporation	✅ Needs business number; GST/HST may not open automatically
Sole proprietor/Partnership	✅ Automatically gets GST/HST account when registering business number (unless exempt)

📌 Key Concepts to Know

✅ GST/HST Business Number vs GST/HST Account

When a business registers, CRA provides:

Business Number (BN) – universal tax identifier
GST/HST account – adds RT extension (e.g., 123456789RT0001)

Many people use the terms “Business Number” & “GST Number” interchangeably — but technically the GST/HST account is a sub-account of the BN.

🏢 Corporations vs Sole Proprietors — Registration Differences

Sole Proprietor / Partnership 👤	Corporation 🏢
GST/HST account usually opens automatically when BN issued	BN issued first, but GST/HST account NOT automatic
Must monitor threshold/exempt status	Must request GST/HST account separately unless automatically assigned
Business + individual legally same entity	Business is a separate legal entity

🛑 Common mistake:
New corporations assume they are automatically registered for GST/HST — they aren’t. Always verify or request CRA to open RT account.

🧠 Exempt vs Taxable vs Zero-Rated Supplies

Type	GST/HST Charged?	Example
Taxable	✅ Yes	Consulting, retail sales
Zero-Rated	❌ No but still eligible for ITCs	Basic groceries, exported services
Exempt	❌ No, cannot claim ITCs	Medical services, daycare, rent (residential)

If business supplies are exclusively exempt, the business must not register.

⚖️ When Registration Becomes Mandatory

If a business exceeds the Small Supplier limit, registration becomes mandatory.
(Detailed small supplier rules covered in the next blog section)

💡 Why Register Even If You Don’t Have To?

Some businesses voluntarily register because:

✅ They want to claim Input Tax Credits (ITCs)
✅ It improves business credibility
✅ They expect rapid growth
✅ Their clients are registered (so they don’t care about being charged GST/HST)

“Should I register voluntarily?” is one of the most common client questions — knowing how to answer builds trust and authority.

🏁 How to Recognize GST/HST Account Formats

Account Type	Ending Code
GST/HST	RT
Corporate Tax	RC
Payroll	RP
Import/Export	RM

Example business profile might look like:

123456789RT0001 → GST/HST
123456789RC0001 → Corporate filing
123456789RP0001 → Payroll

🧠 Pro Tax Preparer Tip Box

💡 Pro Tip:
When a new client incorporates, verify BN and sub-accounts immediately.
Many businesses unknowingly operate without RT activation, risking audits & late penalties.

📣 Red-Flag Situations to Watch For

⚠️ Clients running a business but not charging GST/HST
⚠️ Corporations with BN only, no RT account
⚠️ Businesses thinking exempt = small supplier (not always true!)

📝 Quick Cheat Sheet

Most businesses must register ✅
Exempt supply providers do not register ❌
Small suppliers may skip but should consider voluntary registration 🌱
Corporations must request GST account separately ⚠️
BN ≠ GST account — watch for RT code 🕵️‍♂️

💬 Final Thought for Tax Beginners

Mastering GST/HST registration rules helps you:

Advise clients confidently
Avoid costly mistakes
Build trust & grow your tax practice 💼📈

This is one of the first “consulting-level” skills you will use in real practice — learn it well!

Small Supplier Rule for GST/HST: Full Guide & Criteria 💡📊 (Canada)

The Small Supplier Rule is one of the most important GST/HST concepts in Canada — especially for new tax preparers and new business owners. This rule determines when a business must register for GST/HST and when they are exempt from registration.

This guide breaks it down clearly, with real-world context and practice tips ✅

🎯 What Is a Small Supplier?

A Small Supplier is a business or individual whose worldwide taxable supplies are $30,000 or less in a rolling 4-quarter period.

If you qualify as a small supplier, you do NOT have to register for GST/HST.
However, you may choose to register voluntarily (for Input Tax Credits and credibility reasons).

🧮 What Counts Toward the $30,000 Threshold?

Includes ✅
✔️ Taxable supplies (products/services subject to GST/HST)
✔️ Zero-rated supplies (0% tax — but still taxable category)
✔️ Worldwide sales (Canada + international)

Does NOT include ❌
❌ Exempt supplies (e.g., healthcare, daycare, residential rent)
❌ Employment income
❌ Financial services income (exempt category)

📍 Zero-Rated Still Counts!
If $28,000 taxable + $5,000 zero-rated = $33,000 → You MUST register.

🏆 Important Rule: Worldwide Sales Count

If a Canadian business has customers outside Canada, those sales still count toward the $30K threshold.

The Small Supplier test is based on total taxable worldwide sales, not just Canadian sales.

🔁 Rolling 4-Quarter Test (NOT Calendar Year)

This is crucial — many people misunderstand this.

The CRA uses four consecutive calendar quarters, constantly rolling.

Example:
Quarter 1 + Quarter 2 + Quarter 3 + Quarter 4
Then Quarter 2 + Quarter 3 + Quarter 4 + Quarter 1 (next year)

If at any point those four quarters exceed $30,000, registration becomes mandatory.

🕒 Deadline to Register Once You Pass $30K

Action	Deadline
Threshold passed	Immediately considered required to register
Registration deadline	Within 29 days of surpassing $30K

📍 Once Registered, You MUST Stay Registered

You cannot stop charging GST/HST just because your sales drop below $30K later.

To stop, you must formally deregister with CRA.
Until CRA approves deregistration → you must keep charging tax.

This rule prevents businesses from “jumping in and out” of the tax system.

🏢 Multiple Businesses? You MUST Combine Revenues

If a person owns multiple sole-prop businesses, they must combine revenue for the threshold.

Example:

Business	Annual Sales
Drywall services	$15,000
IT consulting	$12,000
Online electronics sales	$9,000
Total	$36,000 — MUST register ✅

Also applies to associated corporations — CRA prevents using multiple entities to avoid GST/HST.

👨‍⚕️ Exception: Exempt Suppliers

Businesses offering only exempt supplies do not register — even if they exceed $30K.

Examples:
🦷 Dentists
🏥 Medical professionals
🏫 Tutoring (depends on rules)
🏡 Residential landlords

They cannot charge GST/HST and cannot claim ITCs.

📌 Quick Reference Table

Business Type	Must Register?
Taxable business over $30K	✅ Yes
Taxable business under $30K	❌ No, optional
Zero-rated business over $30K	✅ Yes
Exempt supplier	❌ Never register
Multiple businesses crossing $30K combined	✅ Yes

📦 Zero-Rated vs Exempt (Easy View)

Category	Tax Charged?	ITCs Claimable?	Count Toward $30K?
Zero-rated	0%	✅ Yes	✅ Yes
Exempt	❌ No	❌ No	❌ No

📘 Tax Preparer Success Tips 💼✨

⭐ Always check total revenue across all businesses and sources.
⭐ Track rolling 4-quarter revenue, not calendar-year revenue.
⭐ Once registered, client must stay registered until approved deregistration.

⚠️ Common trap:
Client passes $30K in September → thinks they wait until January.
Wrong — must register within 29 days of passing threshold.

📝 Case Example (Simple)

Quarter	Sales
Q1	$5,000
Q2	$8,000
Q3	$10,000
Q4	$9,000
Total	$32,000 — must register ✅

Even though one year = only $32K, the rule applies as soon as 4 consecutive quarters exceed $30K.

🧠 Memory Trick

“30K / 4Q / 29 Days”

30K limit
4-Quarter rolling
29 days to register

🟦 Info Box — Good to Know

Even if small suppliers don’t have to register —
sometimes voluntary registration helps (e.g., business expenses high, clients are businesses).

🎁 Pro Tip Box

If a client sells to consumers (B2C), staying below $30K is sometimes used as a competitive pricing strategy — no GST/HST charged.

If selling to businesses (B2B), register early to look professional & claim ITCs.

🧾 Example: When a Business Stops Being a Small Supplier (GST/HST Canada)

Understanding exactly when a business ceases to be a small supplier is crucial for tax preparers. This example will help you master the rule and confidently guide clients.

👤 Scenario: John’s Consulting Business

John starts a consulting business and decides not to register for GST/HST initially because he isn’t sure he will exceed the $30,000 small supplier threshold.

He monitors his sales during the year:

Period	Sales	Notes
Jan – Jun	$18,500	Below threshold ✅
July 5	$14,000 invoice	This single invoice pushes total above $30,000 🚨

Total = $32,500 → Now above the $30,000 limit

📌 Key GST/HST Trigger Event

✅ The moment John issues the invoice that pushes him over $30,000, he stops being a small supplier.

📆 Important: It does not wait until the end of the year.
🧾 It is triggered by the invoice that crosses the limit.

⚠️ Must Charge GST/HST Immediately

Once John issues the invoice that puts him over $30,000:

He must charge GST/HST on that very invoice
Even if he has not registered yet
He has 29 days to register after exceeding the threshold

🔥 The GST/HST applies to the entire invoice, not just the amount above $30,000.

👉 So John charges GST/HST on the full $14,000 invoice.

📅 29-Day Rule

Action	Rule
Threshold exceeded	Registration becomes mandatory immediately
Deadline to register	Within 29 days
Tax collection	Begins on the invoice that crosses $30K

🧠 Why This Matters

Many taxpayers mistakenly think they only register starting the next year or next quarter — that is incorrect.

The law requires registration as soon as the threshold is exceeded, not at year-end.

Failing to charge GST/HST can result in the business needing to pay the tax out of pocket, penalties & interest.

💡 Practical Tip For Tax Preparers

Encourage clients to track rolling 12-month sales, not calendar year sales.

Use a spreadsheet or bookkeeping software and set an alert at around $25,000 to avoid surprises.

⭐ Quick Summary Box

Rule	Explanation
Threshold	$30,000 in global taxable supplies
Trigger	Invoice that crosses the threshold
GST/HST applies to	Full invoice amount
Registration deadline	Within 29 days of crossing
Must charge tax before registration completed?	✅ Yes

🟦 Example Breakdown

Date	Event	GST/HST Requirement
Jan–Jun	Earns $18,500	No GST/HST required
Jul 5	Issued invoice $14,000 → total $32,500	Must charge GST/HST on this invoice
Next 29 days	Registers	Must continue charging GST/HST

📎 Note Box — Common Mistake to Avoid

🚫 “I only start charging GST/HST on January 1 next year.”
✅ Wrong — you charge on the invoice that crosses $30K.

🏁 Final Takeaways

Track sales continuously, not annually
Once threshold is crossed → register & charge immediately
GST/HST applies to the full amount of the invoice
Client has 29 days to complete registration

🧠 Practical Guide: Navigating the Small Supplier Rules (GST/HST Canada)

The $30,000 small supplier threshold may sound simple — but in real practice, it can get tricky. As a future tax professional, understanding how to handle real-world situations will set you apart.

This guide explains what to expect, how to avoid mistakes, and how to protect clients when dealing with borderline cases.

🎯 Quick Recap — What Is the Small Supplier Rule?

A business does not have to register for GST/HST until its worldwide taxable sales exceed:

✅ $30,000 in any 4 consecutive calendar quarters (rolling)
✅ Or $30,000 in a single quarter

Once passed → registration becomes mandatory and GST/HST must be charged immediately.

🧩 Why It Gets Complicated in Real Life

In theory, you just track sales until they hit $30,000.

In practice, you face challenges like:

Issue	Why It’s Hard
Rolling 4-quarter calculation	Doesn’t always match the business fiscal year
Seasonal businesses	Revenue spikes only in certain seasons
Information delay	Accountants often see data after year-end
Borderline revenue clients	Hovering near $30K requires monitoring

❄️ Example: Seasonal Business Challenge

Think of seasonal businesses like:

Landscaping businesses 🌱
Snow removal contractors ❄️
Summer vendors 🎪

They may:

📍 Earn $28,500 January–December
but
📍 Earn $34,000 in a single summer quarter

They technically must register, but:

Clients may not realize it
CRA may not detect it right away
The accountant sees records months later

⚠️ CRA Reality Check

CRA generally looks at annual income lines on tax returns (e.g., T2125).

So if annual revenue is below $30K, they usually do not pursue registration issues.

💡 But that doesn’t remove the legal obligation — the business still had to register!

As a tax professional, you must advise properly, even if CRA doesn’t automatically catch it.

🧑‍💼 Best Practices for Tax Preparers

✅ Track Clients Near the Threshold

If a client earns:

$0–$15,000 → No need to stress
$20,000–$30,000 → Monitor carefully ‼️
$30,000+ → Registration required

Revenue Range	Action
Below $15K	Low risk — standard review
$20K–$30K	Discuss sales patterns, seasonal spikes
Crosses $30K	Must register & charge GST/HST

✅ Identify Seasonal Clients Early

Ask clients questions like:

📌 Which months do you earn most of your revenue?
📌 Do you have seasonal contracts?
📌 Have you ever billed over $30K in 4 months?

This helps you catch registration triggers before CRA inquiry.

✅ Document Your Advice

Keep a record or direct clients to a webpage explaining the small supplier rule.

This protects you if CRA questions the client later.

🛡️ “I advised the client and provided written resources.”

💬 Pro-Tip Box — Client Communication

🗣️ “The $30,000 limit is based on rolling quarters, not just calendar year. If you’re close, tell me during the year so we can avoid penalties.”

📦 Helpful Tools to Offer Clients

✅ Quarterly revenue tracking spreadsheets
✅ Reminder emails for seasonal clients
✅ A page on your tax website explaining the rule
✅ GST/HST registration guide & deadlines

⭐ Bonus Tip — Register Voluntarily Sometimes

Even if under $30K, registering might help if clients:

✅ Buy equipment & want ITC refunds
✅ Work with corporations that prefer GST-registered vendors
✅ Expect to grow quickly

(You’ll cover these benefits in another section.)

📘 Summary — Practical Small Supplier Rule Management

Key Point	Meaning
Watch $30K closely	Rolling quarters can trigger registration
Seasonal revenue?	Monitor more often
CRA often unaware	But legal obligation still exists
Track & advise early	Protects your clients — and your practice
Document advice	Essential for professional protection

Understanding these real-world nuances is what separates a basic preparer from a trusted tax advisor.

🚀 Why Register for GST/HST Even if You’re Under $30,000? (Beginner-Friendly Guide)

Many new entrepreneurs ask:
“I earn less than $30,000 — do I really need to register for GST/HST?”

Technically — no, you don’t have to until your worldwide taxable revenues exceed $30,000 in a rolling 4-quarter period.

But here’s the secret that great tax professionals know 👇
👉 In many cases, it’s smarter to register before hitting that threshold.

This guide breaks down the real-world reasons why registering early can be a smart financial and business move.

✅ 1. You Can Claim Input Tax Credits (ITCs)

If you’re not registered, every time you pay GST/HST on business expenses, that tax becomes a real cost.

Once registered, you can recover GST/HST paid on eligible business expenses (called Input Tax Credits).

📌 Example

Scenario	Without GST/HST Registration	With Registration
Revenue	$10,000	$10,000 + collected HST ($1,300 in ON)
Expenses	$5,000 + HST ($650) = $5,650	$5,000 (claim $650 ITC)
Outcome	You lose $650 in tax	You get the $650 back

Result: ✅ Profit higher when registered
Instead of losing HST on expenses, you recover it.

💡 If you’re serious about scaling your business, those ITCs add up fast.

✅ 2. Boosts Business Credibility & Professionalism

Clients and companies often see GST/HST registration as a sign of a serious business.

🧠 Psychology matters in business.
Many customers assume:

“If they aren’t registered, maybe they’re not a real business or don’t earn much.”

For B2B clients especially, GST/HST registration:

Shows stability and legitimacy ✔️
Signals you expect growth ✔️
Avoids “small-time operator” perception ✔️

✅ 3. Can Help You Win Contracts

Some businesses won’t work with unregistered suppliers.

This is very common in:

Construction & contracting 🛠️
Design and marketing 🎨
Consulting & services 👔
E-commerce and product businesses 📦

If you don’t have a GST/HST number, they may choose someone else.

❗ Many contractors refuse to hire subcontractors without GST/HST registration.

✅ 4. Especially Important If You Sell Products or Inventory

Product-based businesses benefit the most because:

You often pay GST/HST on supplies & inventory
Without registration, those taxes increase your cost of goods sold

💥 That means lower profit margins if you stay unregistered.

✅ 5. Future Growth Planning

If a business expects to grow, registering early:

Builds proper systems from the start
Avoids scrambling once you cross $30K
Helps avoid costly mistakes (e.g., not charging HST on an invoice when required)

🧠 Smart tax advisors tell clients:
“If you plan to take your business seriously, register early.”

🧠 When Staying Unregistered Might Make Sense

It may be okay to remain unregistered if:

You’re doing small occasional side work or freelancing
You don’t expect to exceed $30,000 anytime soon
Your services are to individuals, not businesses (they can’t claim ITCs anyway)
You want to avoid administrative filing for now

But remember ⬇️

🎯 The moment you cross $30,000, you must register and start charging GST/HST.

📝 Pro Tax-Advisor Tip

Tell clients: If your goal is a real business, treat it like one early.

GST/HST registration:

Doesn’t cost you money
Helps you reclaim tax
Makes you look more professional

📦 Quick Summary

Benefit	Why It Matters
✅ Claim ITCs	Save money on business expenses
✅ Professional image	Clients trust registered businesses
✅ Competitive advantage	Required by many industries
✅ Better for product sellers	Avoid higher costs on inventory
✅ Growth-ready	No scrambling once you hit $30K

📌 Final Thought

Registering early often makes business sense.
And as future tax preparers, this is the advice that builds trust and positions you as a professional.

If a client says:

“I don’t want to charge tax — I’ll lose customers.”

Your answer should be:

“Businesses don’t pay that tax — they claim it back.
It won’t cost them more, and you’re protecting your profits.”

📅 Date of GST/HST Registration & Why It Matters (Canada)

Understanding the date of GST/HST registration is crucial for both new business owners and tax preparers. This date determines when a business must start charging GST/HST, when it may claim Input Tax Credits (ITCs), and how its accounting system should be managed.

This guide explains everything you need to know in a simple, beginner-friendly way ✅

🧾 What Is the Registration Date?

The GST/HST registration date is the effective date set when a business registers for GST/HST with the CRA.

From this date forward:

✅ The business must charge GST/HST on taxable sales
✅ The business can claim Input Tax Credits (ITCs) on eligible expenses
❌ The business cannot treat itself as a small supplier anymore

📌 Important: If a business registers voluntarily (before hitting $30,000 in sales), they still must charge GST/HST from that effective date, even if their sales are low!

⚠️ Key Rules You MUST Know

Rule	Explanation
Once registered → MUST charge GST/HST	Even if sales are only $100!
Small supplier rules no longer apply	Registration overrides small-supplier exemption
Must remit tax collected	Cannot keep GST/HST just because revenue is under $30k
ITCs allowed only after registration date	With some exceptions (see below)
Accounting system must change	Sales and expenses need GST/HST tracking

📊 Example

Situation	What Happens
Business registers June 1	All invoices from June 1 onward must include GST/HST
Business makes only $25,000 that year	Still must charge GST/HST on all $25,000
Business collected GST but didn’t remit	CRA will penalize — big trouble 🚨

✅ Input Tax Credits (ITCs) — When Allowed?

Expense timing	Can claim ITC?
After registration date	✅ Yes
Before registration date	❌ No (with exceptions)

📦 Exceptions — ITCs Before Registration

A business may claim ITCs on certain items owned on the registration date, such as:

✅ Inventory on hand
✅ Equipment still in use
✅ Supplies not yet consumed

📝 Example:
If a business bought office supplies and has half the box left when registering → they can claim ITC on the unused portion.

💡 Pro-Tip for Tax Preparers

Always ask new registrants to list assets, inventory, and unused supplies on hand as of the registration date.

This ensures they don’t miss eligible ITCs 💰

🛠️ Accounting Setup After Registration

Once a business registers:

Add GST/HST accounts in bookkeeping software
Track:
- GST/HST collected on sales
- GST/HST paid on expenses (ITCs)
Ensure invoices show GST/HST number & rate

If using QuickBooks / Xero / Wave → update settings immediately!

🚫 Common Mistakes to Avoid

Mistake	Why It’s Wrong
Charging GST but not remitting	Illegal; CRA audit risk
Thinking threshold still applies after registering	❌ Threshold only matters before registration
Claiming all past expenses	Only allowable for certain assets/supplies

📦 Pro Tip Box

📌 Pro Tip
If your client crossed $30,000, their registration date is the day they exceeded the threshold — not the day they filed!

They must charge GST/HST from that sale onward, even if registration paperwork is pending.

🧠 Final Takeaways

Key Concept	Remember
Date of registration	Sets the start of tax charging & ITCs
Below $30k but voluntarily registered	Still must charge GST/HST
Collected tax but kept it	CRA penalties 😬
Expenses before registration	Mostly no ITCs (some exceptions)

🎯 Bottom Line

Understanding the GST/HST registration date helps you:

✅ Advise clients properly
✅ Avoid CRA penalties & errors
✅ Maximize ITC claims
✅ Maintain compliant records

Whether you’re a business owner or future tax preparer, mastering this rule protects you — and your clients — from costly mistakes. 🛡️💰

✅ What Happens Once You Register for GST/HST (Canada)

Once a business registers for GST/HST, a new phase begins — with new responsibilities, opportunities, and compliance requirements. As a future tax preparer, understanding what happens right after registration is key to guiding clients properly and keeping them audit-safe ✅

This guide breaks down exactly what happens next and what steps you (or your client) should take.

📬 1. CRA Sends Registration Confirmation

After registration, CRA will issue:
📄 GST/HST program account number
📅 Effective registration date
🔁 Reporting frequency (annual/quarterly/monthly)

🗂️ Keep this letter safe — you will need the number for invoices, filings, and CRA interactions.

🧾 2. Start Charging GST/HST Immediately

From the effective date onward:

✅ Must charge GST/HST on all taxable sales
✅ Must issue GST/HST-compliant invoices
✅ Must remit collected tax to CRA
❌ Cannot use small-supplier exemption anymore

📌 Even if sales are below $30,000, once registered — GST/HST is mandatory.

💰 3. Begin Claiming Input Tax Credits (ITCs)

After registration, the business can claim ITCs on GST/HST paid on:

✅ Business expenses
✅ Supplies
✅ Services
✅ Eligible capital purchases

Exception: Some items purchased before registration can also qualify — like inventory and equipment still on hand at the registration date.

🧮 4. Update Accounting Records & GL Accounts

Proper accounting setup is critical.

Businesses (or you, as practitioner) must set up:

Type of Account	Purpose
GST/HST collected	Tracks tax charged on sales
GST/HST paid (ITCs)	Tracks recoverable tax on expenses
GST/HST payable/refundable	Net payable or refund balance

If the client uses software (QuickBooks, Xero, Wave, Sage), update tax settings immediately.

💡 Pro Tip: Many small startups don’t have accounting software — keep thorough working paper notes.

🗂️ 5. Review and Record Assets & Inventory at Registration Date

To maximize ITCs, note the value of:

📦 Inventory on hand
🖨️ Equipment still in use
📎 Supplies not yet used

✅ Keep documentation
✅ Enter into bookkeeping system OR practitioner working papers

⏰ 6. Determine First Filing Deadline

You must know filing frequency and first due date:

Filing Frequency	First Return Covers	Due Date
Quarterly (e.g., June 1 registration)	June 1 – June 30	July 31
Annual (non-fiscal period chosen)	June 1 – fiscal year end	3 months after year-end

🗓️ Add first reporting date to your calendar immediately to avoid penalties.

🧑‍💼 7. Meet the Client & Educate Them

Walk the client through:

✅ How invoices must look
✅ When to charge GST/HST
✅ How to organize expense receipts
✅ When returns are due
✅ How to track GST/HST separately

🤝 Ideally, visit the client’s office to see their setup and guide them.

🧠 Your Compliance Checklist

Task	Completed
Receive CRA registration confirmation	✅
Update accounting system	✅
Create GST/HST ledger accounts	✅
List inventory & assets on registration date	✅
Note filing frequency	✅
Add deadlines to calendar	✅
Train business owner on charging + documentation	✅

🟦 Info Box — Practitioner Tip

📌 Firm Policy Tip
Make a standard onboarding checklist for newly GST/HST-registered clients.
It should include a client meeting, asset list, calendar reminders, and accounting setup steps.

This system protects your clients — and your firm — from costly errors.

🚨 Common Mistakes to Avoid

Mistake	Result
Charging GST/HST but not remitting	Penalties + CRA audit
Not tracking tax separately	Messy filings, missed credits
Missing first return deadline	Interest + penalties
Failing to review inventory at registration	Lost ITC opportunity
Not informing clients about invoice requirements	CRA compliance issues

🎯 Final Takeaway

Once a business registers for GST/HST, tax responsibilities start immediately.
Correct setup and early compliance ensure:

✅ Maximum ITCs
✅ Smooth reporting
✅ Professional business image
✅ CRA-ready records

As a tax preparer, your guidance here builds trust, credibility, and long-term client relationships. 💼🌟
