Expense ≠ VAT

An expense may reduce taxable profit even when its VAT cannot be recovered. Passenger-car costs are the classic example: business deductibility is considered under Articles 22–23, while input VAT on purchase, fuel, maintenance or leasing is normally restricted by a separate VAT rule.

1. What does “tax-deductible” mean?

A deductible expense reduces taxable profit; it does not reduce tax euro for euro. Revenue of €30,000 less €8,000 of qualifying expenses gives €22,000 before other tax adjustments. The €8,000 reduces the tax base rather than creating an €8,000 tax saving.

2. Article 22 conditions

The expense must be incurred in the business interest or ordinary course of business, represent a genuine transaction, be entered in the accounting records, be supported by appropriate evidence and not be disallowed by Article 23.

The question is not only “do I have an invoice?” It is “can I demonstrate why this cost relates to my business?”

3. What does Article 23 disallow?

Key categories include private consumption, income tax, fines and penalties, unpaid social-security contributions, non-genuine transactions and expenses paid incorrectly where banking payment is mandatory. Entertainment, food, accommodation and hospitality also have specific limits. This is not an exhaustive list.

4. What evidence is required?

For ordinary B2B purchases, request an invoice in the business details. Evidence depends on the category and may also include a contract, ticket, toll receipt, bank transaction, lease or other lawful record. The correct rule is “appropriate evidence”, not “nothing is deductible without an invoice”.

5. Does myDATA make the expense deductible?

No. Transmission confirms that data reached the platform; it is not a tax audit. Business purpose, evidence and Articles 22–23 still apply.

Myth: “The supplier sent it to myDATA, so it passes.” Wrong.

6. Business premises rent

Rent for genuine business premises is generally deductible when the lease is properly declared and the premises are used by the business. Rent must be paid electronically or through a banking channel under its specific payment rule, regardless of the general €500 threshold.

7. Home office

Electricity, internet, landline, shared building costs and heating are often mixed costs. Only a reasonable business portion should be claimed, supported by floor area, duration and intensity of use, and the nature of each cost.

For an 80 m² home with a separate 12 m² office, floor area may support an allocation but does not automatically make 15% of every bill deductible. Likewise, one third is not a statutory safe percentage for every home business.

No universal home-office percentage should be applied mechanically.

8. Internet and phones

A dedicated business connection is easier to support. Mixed private/business use needs a reasonable allocation. There is no safe general rule that a mobile phone is “always 50% deductible”.

9. Laptops, phones, monitors and fixed assets

A purchase may be a current expense or a depreciable asset. Computers and software have a 20% tax depreciation rate. An asset with depreciable value below €1,500 may be depreciated fully in the acquisition year. A €1,200 business laptop may therefore be fully depreciated, while a €2,000 laptop normally follows the category’s depreciation schedule.

10. Cars: the most common confusion

Income tax

Fuel, servicing, repairs, insurance, tolls, parking and lease costs are tested under the general business-purpose rules. The old blanket 70%/35% approach is not the current test. Mixed use requires a documented allocation.

VAT

For an ordinary passenger car with up to nine seats, VAT on purchase, fuel, repairs, maintenance and leasing is generally not deductible. Statutory exceptions include relevant vehicle sale or rental businesses and passenger transport for consideration.

Leasing a passenger car does not by itself make fuel VAT deductible.

11. When can fuel VAT be deducted?

CaseFuel VAT
Consultant’s passenger carGenerally no
Leased passenger carNot merely because it is leased
Commercial truck used in taxable businessGenerally yes, subject to normal conditions
TaxiYes, where legal conditions are met
Rent-a-car fleetYes for relevant qualifying use

12. Car leasing

The lease expense may reduce business profit where the vehicle genuinely serves the activity. VAT on an ordinary passenger-car lease is generally blocked. Leasing also does not automatically remove every imputed-income consequence; the contract and liable user must be examined.

13. Business travel

Flights, ferries, rail, taxis, hotels, vehicle rental, tolls and other travel may qualify with a specific business purpose and proper evidence. A planned client meeting can support the cost; a leisure trip does not become business travel because one call was made. VAT on accommodation, meals and passenger transport is a separate issue and is often restricted.

14. Meals, coffee and hospitality

An owner’s daily coffee or meal remains private consumption. Genuine hospitality, events or client meals need a documented business purpose and remain subject to Article 23 restrictions; a client’s presence does not make every meal deductible.

15. Accountants, lawyers and advisers

Accounting, tax, legal, business, engineering and IT services are ordinary qualifying costs when they serve the business and are properly evidenced.

16. Software, SaaS, domain and hosting

Microsoft 365, Adobe, CRM, ERP, antivirus, cloud, AI tools, hosting and domains may qualify when genuinely used in the activity. For foreign suppliers, check supplier country, VAT status, reverse charge and VIES for relevant intra-EU services.

17. Advertising

Google Ads, Meta Ads, websites, SEO, design, branding, printing and promotional material are generally business expenses when they promote the activity. Foreign-platform invoices require correct business details and reverse-charge review; not every foreign supplier requires VIES.

18. Foreign purchases and VIES

The EU and third countries are different. Software from an Irish company may be an intra-EU service subject to reverse charge and VIES. Software from a US company does not use VIES merely because the supplier is foreign.

19. e-EFKA contributions

Paid compulsory social-security contributions are deductible in the tax period recognised by the applicable rules. Unpaid contributions are not deductible while outstanding; late payment requires a check of the actual payment period.

20. Payroll and employer contributions

Salaries, employer contributions, bonuses and lawful benefits may qualify. Payroll has its own electronic-payment rule and is not tested only by the general €500 threshold.

21. Banks, POS and other operating costs

Bank charges, POS and payment-gateway fees, foreign-exchange costs, courier, postage, freight and logistics qualify when connected to the activity. Business liability, equipment and premises insurance may also qualify; purely private insurance does not.

22. Memberships and training

Chambers, professional bodies, databases, journals, online platforms, conferences, certifications and training may qualify where materially connected with the existing activity. Tax training for an accountant or Adobe training for a designer is directly relevant; unrelated personal education is not.

23. Clothing

Ordinary clothing and suits capable of private use are not automatically business expenses. Specialist uniforms, personal protective equipment and genuine branded workwear are assessed differently.

24. Interest, R&D and employee benefits

Business financing interest is subject to specific restrictions; a personal loan is not automatically deductible. Qualifying scientific and technological R&D may receive enhanced deduction under Article 22A with special evidence. Employee meal vouchers have their own tax and social-security conditions.

25. Payments above €500

A purchase of goods or services above €500 may be disallowed when not settled through the required banking method. Business rent and payroll have stricter special electronic-payment rules regardless of the general threshold.

26. Summary: non-deductible costs

CostGeneral treatment
Private shopping, meals or coffeeNot deductible
Income taxNot deductible
Fines and penaltiesNot deductible
Unpaid social contributionsNot deductible while unpaid
Non-genuine or unrelated transactionNot deductible
Insufficient evidenceMay be rejected
Incorrect payment methodMay be disallowed

29. Checklist before recording an expense

✓ Does it genuinely concern the business?

✓ Was it recorded correctly and paid correctly?
✓ Is there private use requiring allocation?
✓ Is it a fixed asset requiring depreciation?
✓ Does it reduce profit?
✓ Is input VAT also recoverable?
✓ Does Article 23 impose a special restriction?
