Bookkeeping and accounting costs €1,200–€2,400 per year depending on transaction volume. A company with 20–50 transactions per month costs approximately €1,200–€1,500 per year. A company with 100–200 transactions per month costs €1,800–€2,400. Monthly management accounts, bank reconciliations, and VAT return preparation are typically included. The accounting fee covers the corporate tax return (IR4, filed by 31 March), provisional tax calculations (two instalments: 50% by 31 July, 50% by 31 December), and the annual return (HE32) filing with the Registrar.
If you have employees, add payroll processing: €200–€500 per month depending on headcount. The TD7 employer return is filed by 30 September each year, and PAYE is paid monthly. If you are VAT-registered, quarterly returns are due by the 10th of the second month after quarter-end (10 February, 10 May, 10 August, 10 November) — preparation costs €200–€400 per quarter, often bundled into the monthly accounting fee. If you pay dividends, the SDC return is filed by 31 January of the following year.
Provisional tax is based on the estimated annual tax liability. If you underestimate by more than 25%, a 10% under-estimation penalty applies on the shortfall. If you overestimate, you can claim a refund — but the refund process can take 6–12 months. The standard approach is to estimate conservatively based on the prior year\'s actual liability, adjusted for known changes. Your accountant should handle this calculation and remind you of the two instalment deadlines (31 July and 31 December).
For a company with €200,000 turnover, 3–5 employees, and VAT registration, the total annual cost breaks down as: registered office €600, company secretary €600, accounting and bookkeeping €2,000, audit €1,800, payroll processing €1,800 (€150/month x 12). Total: €6,800 per year. For a company with €50,000 turnover (below the audit threshold), no employees, and no VAT registration: registered office €600, company secretary €600, accounting €1,200. Total: €2,400 per year — and no audit is required because turnover is below €120,000.
