Understanding Cash Flow Forecasting

Key concepts for managing cash flow in your Irish business

Why is cash flow forecasting important?

Cash flow forecasting helps you predict when your business will have surplus cash and when it might face shortages. This is critical for Irish businesses, especially around VAT return dates (bi-monthly for most) and preliminary tax due dates (31 October / mid-November via ROS).

VAT and cash flow

If your business is VAT-registered (compulsory if turnover exceeds €37,500 for services or €75,000 for goods), you need to account for VAT collected at 23% and VAT paid. VAT collected is not your money -- it must be remitted to Revenue. Plan your outflows to include bi-monthly VAT payments.

Preliminary tax impact

If you are self-employed or a company, preliminary tax must be paid by 31 October each year (extended to mid-November for ROS filers). For companies, Corporation Tax at 12.5% (trading) or 25% (non-trading) must be factored into your cash flow forecast.

Note: This is a simplified cash flow projection. For comprehensive cash flow management including VAT, Corporation Tax, and payroll obligations, consult a qualified chartered accountant.
