Best Accounting Software for Contractors in Ireland (2026) - PAYE vs Self-Employed

Irish contractors typically operate in one of three ways: as a sole trader, through a personal service company (PSC) limited company, or via an umbrella company. Each has different accounting software requirements, different tax obligations, and different relationships with Revenue.

This guide is written for IT contractors, consultants, engineers, and other self-employed professionals working in Ireland - whether through an agency or directly with clients.

Contractor Structure and Accounting Implications

Sole Trader Contractor

Straightforward structure - you invoice clients directly and declare income on Form 11. No corporation tax, no CRO returns, no directors’ duties.

Accounting needs: Invoicing, expense tracking, VAT returns (if registered), and an income/expense summary for your accountant’s Form 11 preparation.

Software: Xero Starter, Zoho Invoice, QuickBooks Simple Start, or Surf Accounts. See Accounting Software for Sole Traders in Ireland for full comparison.

Limited Company (PSC)

The most tax-efficient structure for higher-earning Irish contractors (typically €70,000+ annual revenue). You operate through your own company, pay yourself a mix of salary and dividends, and file both a personal Form 11 and a company CT1 corporation tax return.

Accounting needs: Company accounts (profit and loss, balance sheet), payroll (even if just for yourself), VAT returns, CT1 preparation, and CRO annual return. Significantly more complex than sole trader.

Software: Xero Standard or Plus, Sage Business Cloud, or QuickBooks Essentials. You’ll need a company accountant - most Irish contractor accountants have a preferred platform.

Umbrella Company

You’re employed by an umbrella company and paid PAYE. Zero accounting software needed - the umbrella handles everything. The trade-off is higher cost (umbrella fees of €100-€200/month) and less tax efficiency.

Accounting Software for Irish Limited Company Contractors

If you’re operating through a personal service company, here’s what your accounting software needs to do:

Invoicing - issuing VAT-compliant invoices to your client or agency. Most contractors raise one invoice per month to one client - very low volume.

VAT returns - filing bi-monthly VAT3 returns to ROS (if turnover exceeds €40,000 for services). Direct ROS integration saves time.

Payroll - processing your own salary, calculating PAYE, PRSI, and USC, and submitting PSRs to Revenue under PAYE Modernisation. Even a company with one director-employee needs a payroll system.

Expense tracking - recording allowable company expenses: home office costs, professional development, hardware, software subscriptions, travel to client sites.

Year-end accounts - profit and loss and balance sheet for CT1 corporation tax filing. Your accountant typically prepares these from your accounting software data.

Directors’ loan account - tracking money paid out to yourself that isn’t salary (expenses reimbursed, dividends declared).

Recommended Software for Irish PSC Contractors

Xero Standard is the most popular choice among Irish IT contractors operating through a limited company. Its clean interface handles the low invoice volume typical of contractor businesses, has direct VAT3 ROS filing, and integrates with BrightPay or Collsoft for payroll.

Most Irish contractor accountants are on Xero, which means shared access and faster year-end preparation. The USD billing is a minor irritation; the functionality more than justifies the cost.

Pricing: ~$46/month (Standard). Your accountant fees are the dominant cost - software typically represents 5-10% of your total accounting cost.

Sage Business Cloud is the alternative for contractors whose accountant is Sage-based. Sage’s built-in payroll is an advantage - one fewer system to manage for a single-employee company.

Surf Accounts suits Irish contractors who want euro billing and a local support team. Solid product, particularly if your accountant uses it.

VAT for Irish Contractors

Most Irish contractors with annual revenue above €40,000 (services) must register for VAT and charge 23% VAT on their invoices. Key points:

Reverse charge VAT - if your client is VAT-registered in another EU country (common for Irish IT contractors working with UK or EU clients via Irish agencies), you may not charge VAT on cross-border B2B services. The reverse charge mechanism applies - the client accounts for VAT in their own country. Your accounting software must support this correctly.

Zero-rated exports - invoices to non-EU clients (US tech companies, for example) are typically zero-rated for VAT purposes. Confirm with your accountant.

VAT3 filing frequency - bi-monthly for most contractors. Some lower-volume contractors may qualify for annual filing - ask your accountant.

Payroll for a One-Person Company

Running payroll for yourself through your limited company is straightforward but must comply with PAYE Modernisation:

Set up your company as an employer with Revenue
Run payroll using Irish payroll software (BrightPay, Collsoft, or Thesaurus)
Submit a Payroll Submission Report (PSR) to Revenue after each payrun
Pull Revenue Payroll Notifications (RPNs) at the start of each payroll cycle

Payroll software cost: Thesaurus Payroll Manager is the most cost-effective option for a single-employee company, from ~€120/year for up to 5 employees. BrightPay starts from ~€159/year. Both handle PAYE Modernisation fully.

Most Irish contractor accountants include payroll processing in their annual fee - confirm whether this is the case before buying payroll software separately.

The Contractor Accountant Question

Almost every Irish contractor using a limited company structure uses a specialist contractor accountant. Several Irish accountancy firms specialise in IT contractor and PSC accounting and offer fixed monthly fees (typically €100-€250/month) that cover:

Monthly bookkeeping review
VAT3 filing
Payroll processing
Annual company accounts
CT1 corporation tax return
Personal Form 11 income tax return
Company secretarial (CRO returns)

Given this, your accounting software choice is often driven by your accountant’s preference. Ask your contractor accountant what platform they recommend before signing up for any software.

IR35 / S110 and Off-Payroll Working

Irish contractors working through UK clients need to understand IR35 implications for UK work. Since the UK’s off-payroll working rules changed in 2021, many UK-based clients require contractors to be assessed for deemed employment status. This doesn’t change your Irish accounting structure, but it does affect whether you can claim contractor tax rates on UK-sourced income.

If a significant proportion of your income comes from UK clients via UK agencies, discuss this with your Irish contractor accountant before structuring your income.
