2017/18 Tax Year Key Dates

Right, let’s get organised. Below is a list of dates for the entire 2017/18 tax year that are crucial for your financial well-being. They won’t all apply to you, some only apply to the self-employed or those who are paid through the PAYE system. By making yourself aware of these requirements at the very start of the new tax year, you can save yourself time, stress and worry in the long run.

Check through this list and note which dates you need to work towards. Whether you’re using your smartphone’s diary or an old-school wall calendar – just get everything on there now to avoid any nasty, last minute surprises.

You are probably well aware that missing any of HMRC’s deadlines leads to immediate and cumulative financial penalties. Most people end up getting slapped with a fine because they have left things to the last minute. Not only does prior preparation decrease overall stress levels, it means that you avoid any mistakes that are inevitably made when completing complex paperwork under time pressure. Remember, HMRC also issue fines for mistakes – even when they are genuine.

You work too hard for your money to be spending it on unnecessary fines. Simply noting all the important dates now gives you the best chance of having everything sorted in plenty of time.

Are you owed a tax rebate?

If you have overpaid tax over the last four tax years, then you are entitled to reclaim that amount from HMRC. But you do have to meet this four year deadline, or your money is lost forever.
