Over 100K self access form - how do I know?

[aCupOfTeaSunday]

[Name changed as it is personal finance related.]

First time post here and hope can get some clarification. Thank you very much in advance.

1. 100K calculation period. What is the start and end date to counting the 100K? financial year (i.e. 05/04/2022-06/04/2023) or calendar year (i.e. 01/01/2022-31/12/2022/).

Context: I start a new job in Aug which has a higher salary, I may fall short of 100K if counting from the calendar year.

1. Is the deadline 31st Jan 2023 or can I (afford) wait till April and see if HMRC sends me a self access letter (if they do?)

Googled everywhere but only get segmented information, hope can get some clarification here.

3.I registered on the government's tax online service portal and it shows I am paying correct tax etc and no reminder of the SA form. Does this mean I don't need to fill one?

Thank you very much.

It's called Self-Assessment. You have to sign up for it if you are required: the name gives an indication of this.

Read the stuff on HMRC website to start with. The period is the tax year.

Not clear if you will start your new job on August 2023 or you started it last August 2022 but either way it's 6/4-5/4 following, so depending what you were earning previously you may or may not go over £100k in the first year of your job.

The £100k threshold is for income in the tax year, ie 06/04/2022 - 05/04/2023.

If you started a new job that took you over £100k in August 2022, then you would May need to submit a tax return for 2022/23, which is due 31 January 2024. So a year from now.

Remember most employer pensions are paid via salary sacrifice, which works by reducing your gross taxable income, so you may not have actually breached the threshold.

Best to wait until after April 2023 to see how much you earned and if you need tor register for self assessment or not!

@Christmascracker0 - Thank you very much, this is very clear. Think I will wait till April 2023 to see. I thought I need to fill the SA four months in advance in January 2023 rather than January 2024.
