With automated corporation tax returns, your firm can save hours on your corporate tax returns with our broad set of CT600s, tax schedules all pre-populated with live data from your workpapers. Data from working papers templates, such as the Fixed Asset Register, flow automatically into the tax schedules so you avoid having to manually export data from accounts production software into your tax software, and ensure errors are eliminated. With much of the data pre-populated, the time it takes to produce a final CT return is dramatically reduced.
