This tool gives general guidance to help you understand HMRC correspondence. It is not tax, legal or financial advice, and it cannot tell you the right response for your own circumstances. Deadlines and consequences depend on the exact notice and your situation, so always read the letter itself and, if in doubt, speak to your accountant or a tax adviser. Solar Protect arranges tax fee protection and business insurance; we do not act as your tax agent.
Worried about the cost of an HMRC enquiry? Tax fee protection covers the cost of your accountant defending you. Speak to the team if you want to talk it through.
