FastTax review
A capable Form 11 service, with expert review and filing help at a high one-time price.
Reviewed by iTechGuides Editors · Editorial team · Updated Nov 2026
FastTax is a web-based Irish tax service for individuals filing Form 11 returns. It is aimed at self-employed people, landlords, PAYE earners with additional income, retirees and investors. The service guides users through income and expenses, calculates tax and produces a ROS-compatible Form 11 file. Its coverage includes self-employment accounts, rental income, investment income and capital gains reporting, making it suited to returns that go beyond straightforward employment income.
The three plans are priced as one-time rates: Plan 1 Core costs €145 and includes guided entry, tax calculation and a pre-populated ROS-compatible Form 11 file, but no expert review. Plan 2 Plus costs €240 and adds review of the completed return, checks for errors and missed deductions, and phone support. Plan 3 Premium costs €390 and includes expert review, phone support, submission of the Form 11 to Revenue by FastTax.ie and submission confirmation. The published terms state that prices include VAT and that refunds are unavailable once service commences.
FastTax’s main practical distinction is the choice between preparation, reviewed preparation and a full-service submission option. Plan 1 suits filers comfortable submitting through Revenue Online Service, while Plan 2 adds professional checking without transferring submission responsibility. Premium is the clearest fit for customers who want FastTax.ie to handle the Revenue submission. The service is less suitable for anyone seeking free software, a lower-cost starting point or access beyond the web. Irish solo filers and small operators with mixed income should consider it when expert review or filing assistance matters more than price and platform flexibility.
