E-commerce has exploded in Ireland over the past few years — from local boutiques selling online to new start-ups shipping across Europe. It’s an exciting space with huge potential, but it also comes with new responsibilities that many business owners don’t expect.
At File My Taxes Accountants, we work with Irish online retailers every day — from small Shopify and Etsy stores to larger e-commerce companies. Here’s a straightforward guide to what you should know before (and after) you start selling online.
1. Registering Your Business
If you’re selling goods or services online with the intention of making a profit, you’re running a business in the eyes of Revenue.
You’ll need to:
-
Register your business as a sole trader or limited company.
-
Register for tax – income tax (sole traders) or corporation tax (companies).
-
Register for VAT, if your turnover exceeds the current threshold (€42,500 for services / €85,000 for goods).
Even if you’re selling part-time, once you make regular sales for profit, you need to declare it.
👉 File My Taxes can help you register correctly from the start and avoid headaches later.
2. VAT — The Big One for E-Commerce
VAT is often the trickiest part of running an online shop, especially if you sell to customers outside Ireland.
Here’s what to know:
-
Irish VAT applies when selling to Irish customers.
-
If you sell to other EU countries, the One Stop Shop (OSS) scheme lets you report all EU VAT through one Irish return.
-
If you sell outside the EU, exports are generally zero-rated for VAT, but you must keep proper proof of shipment.
Getting VAT right from day one saves a lot of confusion later — especially if you’re scaling quickly.
👉 We help e-commerce clients register for OSS and manage their VAT returns accurately each quarter.
3. Record-Keeping and Accounting
E-commerce platforms make selling easy, but they can complicate your accounts. Sales, fees, refunds, and transaction charges all need to be recorded correctly.
Keep track of:
-
Sales by country (for VAT).
-
Platform fees (Shopify, PayPal, Stripe, etc.).
-
Advertising and marketing spend.
-
Stock and fulfilment costs.
Using cloud accounting software connected to your platform (like Xero or QuickBooks) makes life much easier.
👉 At File My Taxes, we help set this up and reconcile your sales automatically — no endless spreadsheets required.
4. Tax-Deductible Expenses
Running an online business involves plenty of costs — and many are tax-deductible if they’re wholly and exclusivelyfor your trade.
You can usually claim for:
-
Website hosting and development
-
Online advertising (Google, Meta, TikTok, etc.)
-
Packaging and delivery costs
-
Software subscriptions
-
Photography, design, and branding expenses
-
A business portion of phone, broadband, and electricity if you work from home
Good record-keeping is key. Keep receipts, invoices, and digital records for six years.
5. Banking, Payments, and Cash Flow
Set up a dedicated business bank account so you can clearly separate personal and business income. This makes reconciling payments much simpler and helps track profitability.
Also consider:
-
Choosing payment processors with clear reporting (Stripe, Revolut, etc.).
-
Tracking cash flow — e-commerce sales can fluctuate seasonally.
-
Planning for returns and refunds, which can affect margins.
6. Understanding Duties and Customs
If you sell outside Ireland — even to Northern Ireland or the UK — customs, duties, and VAT import rules may apply.
Post-Brexit, shipping to the UK can require:
-
An EORI number.
-
Correct VAT treatment depending on whether the customer is a consumer or business.
-
Clear customs declarations for goods shipped.
These rules can change quickly, so having an accountant who understands e-commerce trade is a real advantage.
7. Scaling Your Online Business
Once you’re trading successfully, growth brings its own challenges:
-
Do you need to register for VAT in another country?
-
Should you switch from sole trader to a company?
-
How do you manage stock, fulfilment, and cash flow efficiently?
These are the moments when having good management accounts and advice really matters.
👉 Our Business Management Package gives online sellers regular reports, cash flow insights, and full tax compliance — everything you need to grow confidently.
