VAT is a routine part of running many Irish businesses, but it can also be one of the areas that causes the most confusion for new business owners.
When do you need to register? Which VAT rate should you charge? What VAT can you reclaim? And when does the VAT actually need to be reported and paid to Revenue?
For businesses across Leinster, getting these basics right early can help avoid incorrect invoices, unexpected tax liabilities and unnecessary compliance work later.
What is VAT?
Value-Added Tax, or VAT, is a tax on the supply of many goods and services.
A VAT-registered business will generally charge VAT on its taxable sales and may be entitled to reclaim VAT incurred on qualifying business purchases and expenses.
The difference between the VAT collected and the VAT that can properly be reclaimed is then reflected in the business's VAT return.
In practice, the business is collecting and accounting for VAT rather than treating it as part of its own income.
When does an Irish business need to register for VAT?
VAT registration is generally compulsory once turnover exceeds the relevant registration threshold.
The current principal thresholds include €42,500 for persons supplying services only and €85,000 for persons supplying goods. An €85,000 threshold can also apply to certain businesses supplying both goods and services where 90% or more of turnover relates to qualifying goods.
That means a business should not simply wait until the end of the year and look at historic turnover.
If your business is growing and you expect to exceed the relevant threshold, your VAT position should be monitored in advance.
A business below the threshold may also elect to register voluntarily. Whether that makes commercial sense will depend on factors such as your customer base, the level of VAT-bearing costs in the business and the type of supplies you make.
What VAT rate should you charge?
Not every sale in Ireland is subject to the same VAT rate.
From 1 January 2026, Ireland's standard VAT rate remains 23%. Reduced rates of 13.5% and 9% also apply to certain goods and services, with additional specific rates and zero-rating applying in particular circumstances.
The important point is that the VAT rate should be established based on the actual product or service being supplied.
Businesses should avoid assuming that a rate applies simply because another business in the same broad industry uses it.
There is also an important distinction between a zero-rated supply and a VAT-exempt supply. Both can result in no VAT being charged to the customer, but the consequences for recovering VAT on business costs can be different.
Where the treatment is unclear, it is worth checking before invoicing customers.
Output VAT and input VAT
Once registered, there are two concepts that business owners will regularly encounter.
Output VAT is VAT charged on taxable sales to customers.
Input VAT is VAT incurred on purchases and expenses of the business which may, subject to the applicable rules, be deductible against the VAT charged on sales.
This is why keeping proper invoices and records matters.
Revenue requires VAT returns to be true and correct, and businesses need adequate supporting records for the amounts included in their returns.
Not every item of VAT incurred by a business is automatically recoverable, so the nature of the cost and how it is used in the business should also be considered.
How often are VAT returns filed?
The normal VAT taxable period in Ireland is two months.
The standard periods begin in January, March, May, July, September and November. Revenue can authorise different filing frequencies in certain circumstances, including four-monthly or six-monthly periods for businesses with relatively low annual VAT liabilities.
A VAT3 return records the VAT payable to Revenue or the VAT reclaimable by the business for that taxable period.
The normal filing and payment deadline is the 19th day of the month following the end of the VAT period. For businesses filing and paying electronically through ROS, the deadline is extended to the 23rd.
Businesses also generally have an annual Return of Trading Details, or RTD, which provides a breakdown of annual sales and purchases by VAT rate.
Common VAT issues for small businesses
Some of the most common problems arise not from complicated transactions, but from relatively basic matters being missed.
These include:
registering too late after exceeding the threshold;
charging an incorrect VAT rate;
failing to keep valid VAT invoices;
reclaiming VAT that is not deductible;
forgetting to include particular sales;
mixing personal and business expenditure;
filing VAT3 returns late; and
failing to consider different rules for EU or UK transactions.
For businesses selling internationally, VAT can become considerably more complicated because Irish VAT, EU VAT/OSS arrangements and UK VAT obligations can potentially interact depending on what is being sold, where the customer is located and whether the customer is a business or consumer.
VAT should form part of your bookkeeping process
The easiest time to deal with VAT is throughout the accounting period, not the night before the return is due.
Keeping bookkeeping up to date means the business should have a clearer picture of:
VAT collected on sales;
VAT incurred on purchases;
upcoming VAT liabilities;
missing invoices; and
whether the business's accounting records agree with the figures being submitted to Revenue.
It also makes management accounts and cash-flow forecasting more useful.
A VAT liability should not come as a surprise simply because the return deadline has arrived.
