There are multiple dates in the tax calendar. Some will cost you money if you miss them. Here are some of the important ones:
31st January. Online self-assessment deadline. Payment of last tax return and/or 1st payment on account due
5th April, end of tax year
6th April, start of tax year. Self-assessment filing opens
31st July, second payment on account due
You don’t have to remember these otherwise uneventful days anymore. TAXO'D will remind you when there’s something important coming up.
