Configure any tax wrapper with the "Custom" Account in Timeline
Summary
-
Custom tax account enables advisers to model complex investment wrappers not supported by default in Timeline Planning.
-
A Configuration section offers granular tax controls such as withdrawal tax, capital gains tax, growth tax, and IHT exclusion.
-
Allows approximate modeling of all non-standard accounts
Description
Financial plans often include investments in accounts with complex tax treatments like Venture Capital Trusts (VCTs), Onshore Bonds, Loan Trusts, and more.
The Custom account type can become a powerful account to rule them all. The custom account has a Configuration section, which appears in the account page when a custom tax account is selected.
Advisers now have direct control over tax-related behaviours to reflect real-world account dynamics.
