What Expenses Can a Sole Trader Claim in Ireland? (2026 Guide)

If you're a sole trader in Ireland, understanding which business expenses you can claim is important because allowable expenses can reduce the profit on which your business tax is calculated.

But an expense doesn't become tax deductible simply because you paid for it from your business account.

Revenue's basic principle is that deductible expenses must be related to running your business. Some costs are fully deductible, some need to be divided between business and private use, while others aren't deductible from trading profits at all.

Quick answer: Irish sole traders can generally claim qualifying expenses directly related to running their business, including goods for resale, business premises costs, accountancy fees and qualifying vehicle or machinery costs. Personal expenses and certain other costs are not deductible. Where something is used partly for business and partly privately, only the business portion can generally be claimed.

Why do business expenses matter for a sole trader?

A sole trader is generally taxed on the profits of the business rather than simply on the amount invoiced to customers.

At its simplest:

Business income − allowable business expenses = business profit

Imagine your business has:

Income: €60,000

and:

Allowable business expenses: €18,000

A simplified calculation gives:

€60,000 − €18,000 = €42,000 business profit

That does not mean your final tax bill is simply a fixed percentage of €42,000.

Income Tax, PRSI, USC, tax credits, other income and your individual circumstances can all affect the final result.

But it demonstrates why recording legitimate business expenses correctly matters.

What expenses can a sole trader claim in Ireland?

Revenue says deductible expenses can include costs directly related to running your business.

Its current examples include:

• goods purchased for resale
• employees' pay
• rent and bills for business premises
• running costs for vehicles or machinery used in the business
• lease payments for vehicles or machinery used in the business
• accountancy fees
• interest on money borrowed to finance the business

These are examples rather than a rule that every payment within one of those categories is automatically deductible.

The expense still needs to meet the appropriate tax conditions.

Can I claim the cost of stock and materials?

Generally, goods purchased for resale can form part of the costs of running the business.

This can be particularly relevant to:

• retailers
• online sellers
• tradespeople
• manufacturers
• businesses carrying stock
• businesses using materials to provide their services

For example, an electrician purchasing qualifying materials for customer jobs is in a very different position from an individual buying materials for improvements to their own home.

Keep purchase invoices and receipts so there is a clear record of what the business bought and why.

Can I claim business rent and utility bills?

Revenue includes rent and bills for business premises among its examples of deductible business expenses.

If you rent a workshop, office, shop or other premises solely for the business, qualifying costs associated with those premises may therefore be deductible.

The situation becomes more complicated when the premises or utility is also used privately.

That's where apportionment becomes important.

What if an expense is partly business and partly personal?

You cannot generally claim the private part of a mixed-use expense.

Revenue specifically gives examples including:

• telephone bills
• motor expenses
• rent

Where an expense has both business and private use, Revenue says you should determine how much relates to the business and claim only that amount.

Simple example

Suppose a qualifying cost is:

€1,200

and a reasonable calculation shows that:

75% relates to the business

and:

25% is private

The potentially deductible business portion would be:

€1,200 × 75% = €900

You wouldn't simply claim the entire €1,200.

The method used to divide the cost should be reasonable and supported by your records.

Can I claim my mobile phone bill?

A phone used for business can potentially create a deductible business expense.

However, if you use the same phone for both business and personal calls or data, Revenue's mixed-use principle applies.

You should determine the business proportion and claim that portion rather than automatically treating the entire bill as a business expense.

Keeping a separate business phone or plan can make the distinction easier, although the tax treatment still depends on the actual circumstances.

Can I claim broadband and internet costs?

Where broadband or internet costs are genuinely incurred for the purposes of your trade, an appropriate business portion may potentially be deductible.

If the same broadband connection is used by your household privately, you should not automatically claim the entire household bill.

Use a reasonable basis to identify the business element and retain the underlying bills.

Don't confuse this with the separate Remote Working Relief rules for employees. A self-employed person's business expenses are considered under the rules applying to the trade.

Can I claim software and subscriptions?

Software used directly in running your business can potentially be a business expense, subject to the normal rules.

Examples might include qualifying subscriptions for:

• accounting software
• design software
• cloud storage
• project-management tools
• business email
• website services
• specialist software used in your trade

The important question is whether the cost genuinely relates to the business.

A personal entertainment subscription doesn't become deductible simply because the payment comes from your business bank account.

Can I claim accountancy fees?

Revenue specifically lists accountancy fees among its examples of expenses that may be claimed.

That could include qualifying fees incurred in dealing with the accounts and tax affairs of the business.

Keep the accountant's invoice with your other business records.

Good bookkeeping can also make professional accounting work more efficient because your accountant receives organised records rather than a collection of unexplained transactions.

Can I claim advertising and marketing costs?

Qualifying advertising and promotional costs incurred for the purposes of the trade can generally be relevant business expenses.

These might include costs associated with activities such as:

• online advertising
• printed promotional materials
• business cards
• website promotion
• directory listings
• other genuine business marketing

The normal principle still applies: the expense needs to relate to the business.

Can I claim website costs?

Costs genuinely associated with operating and promoting your business online may potentially qualify, depending on the nature of the expenditure.

For example, recurring costs such as certain:

• domain fees
• website hosting
• business email
• website services

may be different in tax treatment from substantial expenditure creating a long-term capital asset.

This distinction matters because revenue expenses and capital expenditure are not treated in the same way.

If you're spending a substantial amount developing or acquiring a long-term business asset, check the appropriate tax treatment rather than automatically entering the entire amount as an ordinary expense.

Can I claim the cost of a laptop or equipment?

This is an important distinction.

Revenue states that capital expenditure cannot normally be deducted as an ordinary expense when calculating business profit.

Capital expenditure can include money spent acquiring certain longer-term business assets such as equipment.

That doesn't necessarily mean there is no tax relief.

Instead, qualifying capital expenditure may be eligible for capital allowances, with the deduction given according to the applicable capital-allowance rules rather than treating the entire purchase as an ordinary day-to-day expense.

So if you purchase equipment for your business, don't automatically assume:

Cost €2,000 = €2,000 ordinary expense this year.

The appropriate treatment depends on what you've purchased and the applicable rules.

What are capital allowances?

Capital allowances provide tax relief for qualifying capital expenditure on certain business assets.

They are different from normal operating expenses.

For example, certain plant and machinery used in a trade can qualify for wear-and-tear capital allowances.

This means your bookkeeping should distinguish between:

day-to-day business expenses

and:

purchases of capital assets

rather than putting every outgoing into one general "expenses" category.

If you're uncertain whether a significant purchase should be treated as an expense or capital asset, professional advice can be worthwhile.

Can I claim vehicle expenses?

Revenue includes running costs for vehicles used in the business among its examples of potentially deductible expenses.

It also specifically identifies motor expenses as an example of a cost that can have both business and private use.

If you use a car or van for your business, see our detailed guide to Business Mileage & Motor Expenses for Sole Traders in Ireland (2026), including how to separate business and private use, what vehicle costs to record, and why Civil Service mileage rates should not simply be used by sole traders.

If a vehicle is used partly for business and partly privately, you need to identify the appropriate business portion.

Relevant costs might include qualifying business proportions of certain running expenses.

However, the treatment of purchasing a vehicle is different from simply paying its running costs because the purchase can involve capital-allowance rules.

Vehicle tax treatment can also depend on the type of vehicle and how it is used.

Keep appropriate records rather than estimating the business use at year-end without evidence.

Can I claim travel expenses?

Some genuine business travel expenses may qualify, but you need to be careful here.

Revenue specifically states that your own food and travel expenses are not generally deductible except in circumstances covered by the relevant Revenue rules.

The tax treatment of travel depends on why the journey was made and the nature of the business.

Don't assume that every journey made while self-employed is deductible business travel.

For example, ordinary travel between home and a regular place of business may be treated differently from necessary travel undertaken in the course of carrying on the trade.

Where travel costs are significant, keep records of:

• date
• destination
• business purpose
• distance where relevant
• associated receipts

Can I claim meals and food?

Your normal personal food costs aren't business expenses simply because you're self-employed.

Revenue specifically excludes your own food expenses except where the circumstances satisfy the rules set out in its guidance on food and accommodation expenses.

Buying lunch during an ordinary working day therefore shouldn't automatically be entered as a business expense.

Different rules can apply where qualifying business travel or other specific circumstances are involved.

Can I claim work clothing?

Ordinary clothing is generally not deductible.

Revenue specifically identifies clothing as a non-deductible expense, with an exception for protective clothing.

That distinction is important.

Buying an ordinary jacket, shirt or pair of shoes to look professional when meeting clients does not necessarily make the clothing a tax-deductible business expense.

Protective clothing required for the work can be treated differently.

For tradespeople, this can be particularly relevant when distinguishing ordinary clothes from genuine protective workwear.

Can I claim business entertainment?

Revenue specifically says that business entertainment expenses cannot be claimed as deductible business expenses.

So paying for entertainment involving customers or business contacts does not automatically make the expenditure deductible.

This is a common area where "business related" and "tax deductible" are not necessarily the same thing.

Can I claim my own wages as a sole trader?

No.

Revenue specifically lists your own pay among expenses that cannot be claimed.

This makes sense because as a sole trader you and the business are not separate in the same way that you and a limited company would be.

Money you take from the business for yourself is not an employee wage expense that reduces your sole-trader profit.

It is important not to confuse:

money you withdraw from the business

with:

a deductible business expense.

Can I claim employee wages?

Revenue includes employees' pay among its examples of expenses that may be deductible.

If your sole-trader business employs staff, qualifying employment costs can therefore form part of the expenses of running the business.

Having employees also creates separate payroll and employer obligations, so the accounting goes beyond simply recording one expense.

Can I claim loan interest?

Revenue lists interest payments on money borrowed to finance the business among its examples of deductible expenses.

The distinction between the loan itself and qualifying interest expense is important.

Borrowing €20,000 doesn't mean you have a €20,000 deductible business expense merely because the money came into and later leaves the business.

The tax treatment concerns the nature and purpose of the borrowing and the associated qualifying costs.

Can I claim expenses from before I started the business?

Potentially, yes.

Revenue's pre-trading expense rules provide relief for certain qualifying expenditure incurred before a trade or profession begins.

Current Revenue guidance explains that qualifying pre-trading expenditure can relate to the three-year period before the trade or profession commences, provided the expenditure would have been deductible if incurred after the business had started.

Examples given by Revenue include:

• accountancy fees
• advertising costs
• feasibility studies
• preparing business plans
• rent for the premises from which the business operates

This can be valuable for a new sole trader who incurs legitimate costs while getting the business ready to launch.

Keep those records even though they pre-date your first customer.

What expenses can a sole trader not claim?

Revenue's current guidance specifically identifies several examples of expenses that cannot normally be deducted in calculating business profit.

These include:

• clothing, except qualifying protective clothing
• your own pay
• business entertainment
• your own food or travel costs except where Revenue's specific rules allow them
• the private portion of mixed-use expenses
• capital expenditure as an ordinary trading expense

Personal expenditure should not be recorded as a business expense merely to reduce taxable profit.

The objective isn't to claim as much as possible.

It's to claim the legitimate expenses to which the business is entitled and maintain records supporting them.

What happens to VAT on business expenses?

If you are VAT registered, there is another important distinction.

Revenue states that where a VAT-registered business is entitled to reclaim VAT on an expense, the deductible expense for Income Tax purposes should not include that recoverable VAT amount.

Simple example

Suppose a qualifying business purchase costs:

€1,230 including €230 VAT

and the business is entitled to reclaim the full €230 VAT.

For bookkeeping purposes, the transaction needs to distinguish between:

Net business cost: €1,000

and:

VAT: €230

rather than simply treating the full €1,230 as the Income Tax expense.

The precise VAT deductibility rules depend on the transaction.

Our VAT3 Ireland guide explains how deductible VAT contributes to T2 on the VAT3.

What if I'm not VAT registered?

If you are not VAT registered and therefore cannot reclaim VAT in the normal way, the treatment of the cost differs because the VAT can form part of the expense cost where the underlying expenditure is otherwise deductible.

Whether you need to register for VAT depends on your business and circumstances.

See our VAT Registration Threshold Ireland guide for the current Irish thresholds and special rules.

Do I need receipts for business expenses?

You need adequate records to support the expenses included in your accounts and tax return.

A bank transaction alone may show that money was paid, but it doesn't always establish:

• what was purchased
• why it was purchased
• whether VAT was included
• whether it was for the business
• whether any private element existed

Keep invoices, receipts and other supporting records associated with the transaction.

This becomes much easier if you record the expense when it happens rather than trying to identify it months later.

How long should I keep expense records?

Revenue generally requires business records to be retained for six years.

That includes records supporting income and expenses.

Our Sole Trader Accounting Ireland guide explains the wider bookkeeping and record-keeping responsibilities for Irish sole traders.

Digital copies can make record keeping much more manageable, provided your records meet the applicable requirements and remain accessible.

A simple way to categorise sole-trader expenses

Rather than keeping one enormous list called "expenses", it is useful to categorise transactions consistently.

For example:

Sales and materials

• stock
• materials
• subcontracted services where applicable

Premises

• rent
• electricity
• heating
• other qualifying premises costs

Administration

• accounting
• software
• business telephone
• postage
• stationery

Marketing

• advertising
• website costs
• promotional costs

Transport

• qualifying vehicle running costs
• qualifying business travel

Assets

• equipment
• machinery
• other capital purchases

The categories you need depend on your business.

The important thing is consistency.

Common sole-trader expense mistakes

Claiming everything paid from the business account

The bank account used doesn't determine whether an expense is tax deductible.

Forgetting mixed personal use

If something is partly private, you generally need to identify the business portion.

Treating equipment as an ordinary expense

Some purchases are capital expenditure and may need to be dealt with through capital allowances instead.

Claiming your own drawings as wages

Money you take from the business personally is not automatically a deductible wage expense.

Claiming ordinary clothes

Revenue specifically excludes clothing other than qualifying protective clothing.

Claiming business entertainment

Revenue specifically identifies business entertainment as non-deductible.

Forgetting pre-trading expenses

Some qualifying costs from up to three years before the business commenced may be deductible.

Losing receipts

If you can't support an expense, you can create problems for yourself if Revenue later asks how the tax-return figure was calculated.

Recording recoverable VAT as part of the expense

VAT-registered businesses need to distinguish recoverable VAT from the underlying expense where applicable.

A practical expense checklist

Before recording something as a business expense, ask:

1. Was this genuinely incurred for my business?
2. Is any part of it personal?
3. Do I have an invoice, receipt or other supporting record?
4. Is it an ordinary expense or a capital purchase?
5. If I'm VAT registered, is any VAT recoverable?
6. Have I categorised it correctly?

If you're uncertain about a significant or unusual expense, check Revenue guidance or ask a qualified tax professional rather than guessing.

How MyLedgerBook helps with business expenses

MyLedgerBook is accounting software built specifically for Irish businesses.

Instead of collecting receipts and trying to reconstruct your expenses at tax-return time, you can record expenses as the business incurs them.

That helps keep:

• supplier details
• expense amounts
• paid and unpaid bills
• input VAT where applicable
• supporting records
• expense categories

connected to your bookkeeping.

For VAT-registered businesses, correctly recorded expenses help prepare the VAT figures needed for your VAT3.

For sole traders, keeping expenses properly organised also helps build the accounting figures needed when preparing your annual Income Tax information.

MyLedgerBook does not decide whether a particular expense is legally deductible for your individual circumstances, and it doesn't file your Revenue return for you.

You remain in control of the records and can review them yourself or with your accountant.

The objective is much simpler:

Record the expense when it happens, keep the evidence with it and avoid rebuilding a year's accounts from receipts at tax time.
