VAT & GST Registration Guide for New Businesses

TL;DR: VAT/GST registration is mandatory once you exceed the turnover threshold in each country, and carries strict invoicing and filing obligations. Voluntary registration below the threshold often makes sense for B2B businesses that want to recover input tax from day one.

What You Need to Know

Value Added Tax (VAT) and Goods and Services Tax (GST) are consumption taxes charged on most business sales of goods and services. They are the largest source of tax revenue for most governments and the most administratively demanding tax for small businesses to manage.

The mechanics are straightforward: you charge VAT/GST on your sales (output tax), you pay VAT/GST on your purchases (input tax), and you remit the difference to the government. If your output tax exceeds your input tax (normal for most businesses), you pay the difference. If your input tax exceeds your output tax (common for exporters and businesses in early growth stages with high capital investment), you receive a refund.

The complexity lies in: knowing which of your products and services are taxable (and at what rate), understanding the thresholds and timing of registration, issuing compliant VAT invoices, and filing returns accurately on time.

How It Works: A Practical Overview

Understanding VAT/GST Rates

Most jurisdictions apply multiple rates:

Standard rate: Applied to most goods and services

Reduced rates: Applied to specified categories (food, healthcare, residential property in the EU; no reduced rates in Australia or NZ)

Zero rate: Taxable supply but at 0% (often exports, international services, some food items)

Exempt: Not subject to VAT at all — and the seller cannot recover input VAT on related costs

The distinction between zero-rated and exempt is critical: if your sales are zero-rated, you can still reclaim input VAT on your costs (making you effectively a VAT-free business). If your sales are exempt, you cannot reclaim input VAT — the VAT on your costs becomes an irrecoverable cost.

Standard rates (2024):

• UK: 20% (standard); 5% (reduced); 0% (zero-rated)
• France: 20% (standard); 10%, 5.5%, 2.1% (reduced rates)
• Sweden: 25% (standard); 12%, 6% (reduced)
• Australia: 10% GST (standard); some supplies GST-free or input-taxed
• New Zealand: 15% GST (standard, broad-based with few exemptions)
• Canada: 5% GST federal (standard); provinces add PST/HST (combined 5–15%)
• USA: No federal VAT; sales tax rates vary from 0–10.75% by state and locality

Registration Thresholds

You must register for VAT/GST when your taxable turnover reaches the threshold. Key dates: in most countries, the trigger is either when you exceed the threshold over the past 12 months, or when you expect to exceed it in the next 30 days.

Should You Register Voluntarily?

If you are below the registration threshold, you can still register voluntarily in most countries. Should you?

Arguments for voluntary registration:

• Recover VAT/GST on business purchases from day one (can be significant for capital-intensive businesses)
• Professional credibility with VAT-registered B2B customers (who can reclaim the VAT you charge them)
• Avoid a disruptive mid-year price increase when you cross the threshold

Arguments against:

• Increased administrative burden (quarterly returns, VAT invoicing compliance)
• If most of your customers are consumers (B2C), charging VAT makes you 20% more expensive than non-registered competitors below the threshold
• Compliance costs (accounting software, accountant time for returns)

For most B2B businesses, early voluntary registration is usually advisable. For B2C businesses below the threshold, the calculation is more nuanced.

Schemes and Special Rules

Many countries offer simplified schemes for small businesses:

UK Cash Accounting Scheme: Pay VAT when your customers pay you (not when you invoice them). Useful for businesses with slow-paying customers. Available if taxable turnover is below GBP 1.35M.

UK Flat Rate Scheme: Pay a fixed percentage of gross turnover (varying by industry, 4–16.5%) instead of calculating actual VAT on each transaction. Simplifies administration for very small businesses.

Australian GST Cash Basis: GST is accounted for when cash is received/paid rather than when invoiced.

French Franchise en Base: Exemption from charging VAT if below threshold — but no input VAT recovery.

Canada Quick Method: Simplified calculation for small businesses (taxable supplies below CAD 400,000).

Filing Requirements

Once registered, you must file VAT/GST returns at specified intervals:

• UK: Quarterly (monthly option available; mandatory for large businesses)
• France: Monthly (quarterly for small businesses under certain thresholds)
• Sweden: Monthly or quarterly depending on turnover
• Australia: Monthly, quarterly, or annually (for very small businesses)
• New Zealand: Monthly, 2-monthly, or 6-monthly
• Canada: Monthly, quarterly, or annually
• USA: Varies by state, typically monthly or quarterly

Returns must be filed on time even if the amount is nil. Late filing penalties apply in all jurisdictions.

Country-by-Country Comparison

Common Mistakes to Avoid

1. Registering late. When you exceed the registration threshold, you must register immediately (registration is typically effective from the date of exceeding the threshold, or the next day if you reasonably expected to exceed it). Late registration means you are liable for VAT on all sales since the threshold was crossed — even if you did not collect it from customers.
2. Charging VAT to customers before you have a registration number. You cannot legally charge VAT until you have a VAT registration number. If your application is pending, issue invoices showing "VAT registration pending" and issue corrected invoices once your number is confirmed. Some countries allow you to show zero VAT while registration is in progress.
3. Incorrectly treating zero-rated supplies as exempt. Both zero-rated and exempt supplies are "not charged at 20%," but the difference matters enormously: zero-rated suppliers can reclaim input VAT on costs; exempt suppliers cannot. Getting this wrong causes systematic over- or under-recovery of input VAT.
4. Not keeping VAT invoices from suppliers. To claim input VAT on purchases, you need a valid VAT invoice from each supplier showing their VAT number, the VAT amount, and your details. A credit card statement alone is not sufficient for input VAT reclaim in most jurisdictions.
5. Missing the VAT return deadline. Late VAT returns attract penalties and interest, even for small amounts. Set calendar reminders for filing deadlines. Most jurisdictions offer direct debit payment options that prevent missed payment deadlines.

Frequently Asked Questions

Q: Do I charge VAT/GST on international sales?

A: Generally: goods exported to overseas customers are zero-rated (you charge 0% VAT/GST but can reclaim input VAT/GST). Services exported to overseas business customers (B2B) are typically outside the scope of VAT/GST in the supplier's country under the "place of supply" rules. Services sold to overseas consumers (B2C) may require you to register and charge VAT/GST in the customer's country — this is the EU's OSS (One Stop Shop) regime for digital services. The rules are complex and depend on the nature of the service and the customer's location. Consult a qualified tax advisor.

Q: Can I reclaim VAT paid before my business was VAT-registered?

A: Yes, in most countries. In the UK, you can reclaim VAT on goods purchased up to 4 years before registration (if still in use) and on services purchased up to 6 months before registration. Similar provisions exist in Australia (4 years) and most EU countries. Keep pre-registration VAT invoices — they have value.

Q: What is Making Tax Digital (MTD) in the UK?

A: Making Tax Digital for VAT requires VAT-registered businesses in the UK to maintain digital records and submit VAT returns using compatible software (via HMRC's API) rather than manually entering data on HMRC's website. MTD for VAT applies to all VAT-registered businesses (from April 2022). MTD for Income Tax (self-assessment) is planned from April 2026 for businesses and landlords with income above GBP 50,000. Non-compliance risks penalties. Most modern accounting software (Xero, QuickBooks, FreshBooks) is MTD-compatible.
