Quick answer

How much does a Self Assessment tax return cost?

A done-for-you personal Self Assessment tax return (SA100) typically costs from around £99 for a straightforward return, rising with complexity such as multiple income sources, rental properties, capital gains, or foreign income. The deadline to file online is 31 January following the end of the tax year on 5 April, and the same date is the deadline to pay any tax owed. HMRC charges an automatic £100 penalty for filing even one day late, with further daily penalties after three months, so filing early is the cheapest and least stressful option.
