Frequently asked questions
need more info?
Everything you need to know about switching to TaxCalc.
How long does it take to switch from IRIS to TaxCalc?
The typical migration takes 2-8 weeks. This timeline includes data transfer, setup, and staff training. We plan the switch around your practice's schedule, with most firms completing their move during quieter periods. Our structured process means minimal disruption to your daily operations.
Is TaxCalc compatible with both desktop and cloud environments?
Yes – we offer both desktop and cloud solutions, with complete flexibility between the two. You can run taxCalc purely on desktop, fully in the cloud, or mix both approaches. This means your team can work remotely or in the office, accessing the same powerful features and shared database wherever they are.
Will I receive support during the migration process?
Our UK support team manages your entire migration journey. We start with a detailed planning phase, handle the data transfer, provide comprehensive staff training, and offer post-migration support. You'll have a dedicated migration specialist, plus direct access to our support team, who maintain our industry-leading NPS score of 81.
How much can I save by switching to TaxCalc?
Our clients typically save up to 40% on their annual software costs compared to IRIS. This comes from our transparent pricing model, no hidden fees, and modular approach – you only pay for what you need. Plus, with no long-term contracts, you're not locked into rising renewal costs.
What makes TaxCalc’s UI better than IRIS?
Our modern interface is built around how accountants work. Every module shares the same intuitive design, reducing training time and errors. We've stripped away unnecessary complexity - common tasks need fewer clicks, and key features are exactly where you'd expect them. This practical approach earned us Best Tax Preparation and Best Accounts Production awards in 2020 and 2021, voted for by 7,500 accountants.
