Simplify Self-Assessment Filing for Your Clients

The self-assessment tax returns in Ireland are becoming more challenging for accounting firms to manage, especially during peak filing seasons. The individuals who are obliged to file under self-assessment are sole traders, directors of companies, landlords, individuals with capital gains or investment income, and any person whose income is not fully covered by PAYE. 

These clients usually have complex returns, multiple sources of income, detailed relief claims, and cross-border issues; all of these aspects need to be reviewed carefully and in compliance with the criteria used by the Revenue Commissioners. 

Managing such a level of detail can consume considerable time for your team and lead to delays, review bottlenecks, and additional workload at peak times. That is where Aone Outsourcing Solutions serves your firm.

Aone Outsourcing Solutions offer complete Form 11 preparation and self-assessment outsourcing services, helping your accounting firm scale efficiently without sacrificing accuracy or client satisfaction. So that you don't have to put an extra burden on your in-house staff.

Who must submit a self-assessment tax return in Ireland?

Self-assessment applies to individuals whose tax liability is not fully collected through PAYE. This includes sole traders, company directors, landlords, individuals with capital gains, those earning investment or foreign income, and anyone with multiple income sources. Such individuals must submit a Form 11 annually to Revenue by 31 October.
