What happens the following year(s) after GILTI tax planning?

When GILTI planning is done correctly, you shouldn’t need an in-depth plan in subsequent years. However, like any plan, it’s important to check in regularly to make sure that the plan still makes sense. Each year, a year-end review can show whether changes in your business or the tax law might materially affect the original GILTI plan. Think of this as a GILTI “check-up.”
