In NZ we generally don't have ANY deductions (nor a tax on capital gains) - this makes filing tax easy - if you have one employer chances are they got your tax exactly right - most people don't even need to file - and certainly none of that fluffing around telling your employer how many 'deductions' you want them to fudge your PAYE with. As an employer it's equally simple, I do my payroll with a simple line in a spreadsheet.
