This will apply to my friend, as her recent 2024/25 self assessment is over the £50,000 threshold
Based on reading up a few weeks ago…..
Her 2025/26 self assessment will be due in 2027 as standard, but she begins MTD quarterly submissions this year for 2026/27, followed by the full self assessment in 2028)
(that means she is looking at sorting out the 25/26 early to get rid of it, or keeping to her normal timetable to concentrate on the MTD)
There have been early voluntary trials of MTD, and this ‘first’ year apparently won’t have late penalties against the quarterly MTD dates - but they must all be submitted before the full self assessment can be submitted - so putting it off will just compress all
of the grief into a limited time
As you are around the £30,000 then unless that includes other things such as PAYE that don’t apply then add one year to the following dates
(simple for me as mine is in the pocket money zone of requiring self assessment but nowhere near any of the planned periods)

there is a wide range of MTD software, which is chargeable or free, may be included with your banking, and can be either linked to your existing accounting or handled on a standalone basis
When we spoke she had not decided on software, but was veering towards dedicated software - the disadvantage being another piece of admin repitition, but the ‘advantage’ of being able to cross check it
