Which Business Expenses Can Reduce Tax Liability in Ireland?

Whether you are a sole trader or an SME, knowing which Business Expenses can reduce your business tax liability in Ireland is vital.


The Irish tax system is quite complicated which is why you require help from accountants sometimes to negotiate it. Under the Irish taxation system, certain expenses within your business are allowable, and some which aren’t.


The difference between a Business and Personal expense


As a director of a company, you are allowed to claim expenses either directly from the company’s business bank account or have them reimbursed at a later stage. That is why it is important to keep a precise record any time the company reimburses you. An example might be somebody buying coffee for the office canteen. They are entitled to be reimbursed for that product because it has come out of their money and not out of company money.


A personal expense is for an individual. These expenses generally cannot be claimed as business expense. An example of this would be buying yourself a coffee because you don’t like the taste of the one in the canteen. This type of expense is not reimbursable by the company.


If you run a small business, your employees can also claim expenses, so it’s good practice to have a company expense form.


Revenue (  is very clear on which expenses can be treated as ‘allowable expenses’.


These expenses can help reduce your tax liability whether undertaken as a sole trader or limited company. 


As we said at the outset, Irish tax law is complicated so if you would like further advice on your specific situation contact us today for a free consultation.


You can deduct the actual business expenses you or your company paid in the operation of the business when filing your tax return. However, the expenses you can deduct are limited to the costs of running your business for a particular period.


What Business Expenses you can deduct from your income


Because the expenses area is so vast depending on what industry your business is in below is a broad outline of what is allowed and what is not allowed as business expenses.


Getting clear on what you can and can’t deduct


You can claim expenses for travel and meals for employees traveling to or from the workplace.


Buying a new suit to attend a meeting would not be tax deductible while if you are in a specialist job like a diver or miner, the workwear you need for those is specialised to that work and therefore would be deductible.


One of the areas that have been historically abused is Client Entertainment and as a result, is now one of the most closely examined by Revenue.


Client Entertainment


Most of the client entertainment expenditure is not tax-deductible. You can add it as an expense while preparing your accounts When it comes to calculating your Corporation Tax those expenses will be added back and therefore disallowed.


Use of your Home

Since the pandemic, how working from home has been treated has changed vastly.

Directors and employees are allowed to claim for the extra cost of lighting and heating. They can also claim for internet provision and/or mobile and landline phone rental.


As a business owner, you will need to establish the proportion of household costs used by the business. You will need to calculate the percentage of your property which is used for business purposes. Once that is done some of that utility bill can be apportioned to business use.


Staff Entertainment


Another area that came under the microscope due to the level of abuse. This expense covers items such as the staff Christmas party or other general moral events within the business. Businesses can also avail of the small benefit exemption for their employees. Each employee can receive up to €1000 tax fee in the form of a voucher once a year. The business is allowed claim this as an allowable expense. 


Telephone Costs


If you have an exclusive broadband/mobile line for your business, the whole amount is allowable.

If you claim business-only calls made on your mobile or landline phone bill, this is an allowable expense provided you can prove it was a business call. 


Additional Allowable Expenses For SMEs


1) Rent – For example, the cost of office rent or production facilities, whether they are shared or exclusive to your company; Office equipment, such as computers or printers; Telephone land lines; Office furniture, such as chairs and desks; or any other equipment used in connection with the business such as computers.


2) Office utensils – The cost of computer software and utensils such as internet access, e-mail software, word processing software, or database systems used by the business.


3) Supplies consumed by your business – including paper products (for example envelopes), toiletries (for example soap), stationery (for example pens), cleaning products etc.
