Missed the 5 October Self Assessment registration deadline? Don’t panic, but don’t ignore it either.
If you’re newly self-employed, started renting out a property, earned income outside PAYE, or have untaxed income to report, you may still need to register with HMRC.
Leaving it until January can create unnecessary stress, especially if you still need to gather records, understand what expenses you can claim, and work out what tax may be due.
The sooner you deal with it, the easier it is to get back on track. Not sure whether you need to file? Speak to APS Advisory.
