When it comes to managing your finances, every euro truly counts. Yet, time and time again, many small businesses across Ireland leave money on the table simply because they overlook valuable tax deductions.
Not to worry — today, we’re lifting the lid on the top 10 tax deductions Irish small businesses often miss, helping you keep more of what you earn. Let’s get stuck in!
1. Home Office Expenses
Working from home? You may be entitled to claim a portion of your household costs — think heating, electricity, broadband, rent or mortgage interest. The key is keeping a reasonable record of the space you use exclusively for business purposes.
Pro Tip: Revenue expects claims to be fair and proportionate, so make sure you can justify your figures if asked.
2. Pre-Trading Expenses
Setting up your business wasn’t free — and guess what? Many of those initial costs (like legal fees, marketing, or professional advice) incurred before you officially started trading are tax deductible.
Important: Pre-trading expenses must be incurred within three years of starting the business and must relate directly to the trade you’re now running.
3. Professional Fees and Subscriptions
Memberships to professional bodies, trade associations, or industry-specific organisations are often allowable expenses. Legal and accountancy fees (for regular business operations) also fall under this category.
Tip: Make sure your memberships are directly relevant to your business activities to qualify.
4. Bad Debts
If you’ve invoiced a customer and tried everything reasonable to collect payment, but the money remains unpaid, you may be able to claim it as a bad debt and deduct it from your taxable income.
Heads Up: There are specific conditions — for example, the debt must have been previously included as taxable income.
5. Motor Expenses
Using your personal vehicle for business purposes? You can claim motor expenses — fuel, maintenance, insurance, and even leasing costs. Alternatively, some small businesses opt for Revenue’s flat-rate mileage allowances to simplify things.
Note: Only the business-related portion of your driving counts.
6. Training and Development
Investing in training courses, seminars, or workshops that enhance your (or your staff’s) skills? These costs are usually tax deductible — as long as they’re directly relevant to your trade.
Watch Out: Personal development courses unrelated to your business usually won’t qualify.
7. Bank Charges and Interest
Business account fees, service charges, and even loan interest for business purposes are deductible expenses.
Small detail, big impact: Keep your business and personal accounts separate to make this deduction crystal clear to Revenue.
8. Marketing and Advertising
Whether you’re running Google ads, designing a new website, printing flyers, or sponsoring a local event — your marketing and advertising spend is usually fully deductible.
Reminder: The marketing must promote your business activities. Personal branding or unrelated sponsorships could cause issues.
9. Pension Contributions
Setting up a pension scheme not only secures your future but can also offer significant tax relief now. Contributions made through an approved occupational pension scheme can be deducted against your profits.
Smart move: It’s a win-win — saving tax today while investing for tomorrow.
10. Capital Allowances
Buying equipment, machinery, computers, or office furniture? Instead of claiming the full cost upfront, Irish businesses use Capital Allowances to spread the deduction over several years.
Extra Tip: Even second-hand equipment qualifies — and don’t forget about the Accelerated Capital Allowance (ACA) for energy-efficient equipment!
Final Thoughts: Small Changes, Big Savings
Tax rules can seem overwhelming, but missing these common deductions could cost your business dearly over time.
The truth is, being proactive and working closely with an experienced advisor can turn your finances around. A second set of expert eyes often spots opportunities you didn’t even know you were missing.
