Yes for sure it's complicated and yeah I have to pay a lot but I use my accountant all year round, not just at tax return time. Without disclosing more than I want to here it's difficult to explain.
Ok, so I get that your employer removes tax and pays to the government prior to you getting paid, but can't you do a claim for "deductions" to reduce your taxable income to them potentially get a tax "return" from the government?
