Most accountants appear once a year with a tax bill. Forti keeps your books current every month, flags what matters before it becomes a problem, and gives you the financial clarity to run your company with confidence — not guesswork.
A decade ago, monthly management accounts were something only larger businesses could justify. Cloud accounting eliminated the manual data entry that made them expensive — and made real-time financial visibility the standard, not the exception.
Most Irish limited companies start with a traditional accountant who files the year-end accounts and tax return. That covers compliance — but it leaves directors making decisions without current information all year.
Six core service areas available within our monthly accounting packages. Exact inclusions depend on your plan — management accounts and payroll are available on specific plans or as add-ons.
Five stages — from onboarding through to year-end — designed so you spend as little time on finance admin as possible.
Beyond the compliance cycle, Forti advises on the reliefs, structures and planning opportunities that make a material difference to what a company pays and keeps.
The most common financial planning question Forti gets from Irish directors. There is no single correct answer — but the structure matters significantly to what you keep.
Forti maintains a forward compliance calendar for every client. This table covers the main recurring deadlines — with the consequences of missing each one.
| Obligation | Deadline | Filed with | Consequence of missing | Risk |
|---|---|---|---|---|
| CRO Annual Return (B1) | Filed within 56 days of the ARD. First ARD is 6 months after incorporation; no financial statements are attached to the first B1. Subsequent B1s carry full financial statements | CRO | €100 initial late fee + €3 per day (max €1,200 per return) + €20 filing fee. Loss of audit exemption where late filing occurs more than once within any five-year period (since 16 July 2025) | High |
| Preliminary Corporation Tax | Small companies (prior-year CT ≤€200k): 31 days before the accounting-period end and no later than the 23rd of that month. Large companies: sixth-month and eleventh-month instalments | Revenue (ROS) | Interest on any underpayment of preliminary tax from the due date | High |
| Corporation Tax (CT1) | Within 9 months of the accounting-period end and no later than the 23rd day of that ninth month (ROS filers) | Revenue (ROS) | 5% surcharge on tax due (max €12,695) if under 2 months late; 10% (max €63,485) if later. Late filing can also restrict loss relief, group relief and excess capital allowances | High |

| Annual VAT RTD | Generally within 23 days of the end of the accountable person's tax/accounting year (ROS filers) | Revenue (ROS) | Revenue query risk — RTD reconciles against VAT3 returns filed during the year | Lower |

Allowable expenses reduce the company's taxable profit and therefore its Corporation Tax bill. Getting this right — claiming everything allowable and nothing that isn't — is part of the monthly bookkeeping service.
