This is what you pay yourself out of the business. You pay tax on the amount of your profit and not on the amount of Drawings you take from the business. However you have to tell the Revenue how much they are so that the Revenue can see you have enough Drawings to live on.

Q20. I work from home. Can I claim my mortgage as a business expense?

You could claim part of your mortgage interest as an expense based on the amount of space used in your house as an office. However, you could be reducing the benefit of the capital gains tax exemption for your private home so this matter needs to be carefully considered.

Q21. When working from home how do I claim for Light and Heat if not separately billed?

Separate billing is not required provided a reasonable amount only is claimed as a business expense having regard to the nature of the business.

Q22. Can I claim for home phone rentals and calls?

Yes. However we recommend that you obtain separate lines for business use and then the full cost can be claimed as a business expense. Otherwise if you use the house phone for business you can claim a fraction of the bill based on how much you use it for business.

Q23. Can I claim the cost of Office Furniture and Equipment for tax purposes?

Yes, subject to the normal rules i.e. the cost is allowed over a period of eight years.

Q24. Can I charge a rent for the use of my house?

If the house is owned in joint names and you carry on business in your sole name then the answer is yes, but it must be a reasonable rent having regard to your circumstances. Remember that the rent received is subject to tax under rental income rules. Generally speaking a rent is not charged for use of one’s house.

Q25. If I run my business from home and I sell the house will I pay capital gains tax on the sale?

You may have to pay capital tax if you sell your house at a profit in proportion to the amount of space used for business purposes. This is an important matter that needs to be kept in mind when running your business from home. The benefit of either claiming mortgage interest relief as a business tax deduction (as distinct from the normal tax relief for mortgage interest) or of charging a rent for the space used needs to be weighed up against the Capital Gains Tax exemption for selling your house.

Q26. If I benefited from the owner-occupiers stamp duty relief when buying the house is there a problem in running my business from home?

Assuming the business is of a minor nature and you do not charge a rent for the use of same then in practice there should be no difficulty.

Q27. I rent an apartment and run my business from it. Can I claim the rent as a business expense?

Yes, based on how much of the apartment is used for business e.g. using 50% of the apartment as an office then claim 50% of the rent as an expense.

Q28. I use my car for business purposes. How do I claim tax relief for it?

There are two separate tax claims. One for the annual running expenses (ongoing expenses) e.g. petrol, tax, insurance, repairs etc. and the other for the capital cost of the car as a Fixed Asset.

Q29. How much of the annual running costs can I claim as a tax deduction?

You claim is based on the percentage business use of the car e.g. Total annual running costs €5,000 Business Use 75% Tax claim for €3750 (€5,000 x 75%)

Q30. I paid €30,000 for the car in 2023 How much of this can I claim?

The limit for cars is €24,000 and you can claim 12 ½ % (1/8th) of this figure multiplied by the percentage business use of the car. Example- Car cost €30,000 Limit €24,000 = Annual Claim € 3,000 X (% Business Use) 75% = Tax Claim €2,250. This claim is allowed every year up to a maximum of 8 years from year of purchase provided you continue to use the car for business purposes. If all this sounds very confusing, our Fixed Assets calculators do all the figure work for you.

Q31. Can I claim a mileage allowance for motor expenses?

No, self-employed people cannot charge themselves mileage. You claim for motor expenses as explained in Q23.

Q32. I paid €1,500 for new computers. How do I claim this as a tax deduction?

The cost is allowed for tax over 8 years at 12.5% per annum as a Fixed Assets claim. The annual claim is €188.

Q33. Three years ago I paid €2,400 for a laptop which is now broken and useless. I claimed my annual tax allowance as a Fixed Asset for the last 3 years. What do I claim now?

As the laptop is now useless you can claim for all of the remaining 5 years of the Fixed Asset claim at once. The tax claim is for €2,400 x 12.5% x 5 = €1,500 Our calculators do this for you.

Q42. Can I reduce last year’s tax bill by making a pension contribution?

Yes if you make the payment and claim for the tax relief by the 31st October in the following year.

Q43. How do I know what amount I should pay as a pension payment?

Our pension calculator does this for you as it depends on your age and amount of your income.

Q44. Are Vat returns hard to complete?

No they are relatively easy. You have to add the total Vat you have collected from customers and take off the Vat you have paid to suppliers and the difference will either be a Vat refund owed to you or Vat owed to the Revenue. Our online accounts system will do all of this for you.

Q45. How often do you have to make Vat returns?
