The MTDfITSA saga has been running for many years,
and as of 23 November 2023, this is the current state:
Go live: start 5
April 2026 and apply to a way smaller base than the original intended group of
4.5 million users. These are the key changes and points:
- Who is
in? Self-employed people and
property landlords (outside of Limited companies) need to register. Initially, landlords with joint property
ownership are not mandated to join (HMRC must provide more
information). Individuals MTDfITSA that previously did a Self
Assessment can have ten or multiple self-employment businesses and 0 to 3
(4 - Foreign property is unclear) property businesses under MTDfITSA (Ord
UK property, FHL UK, FHL EEA, Foreign property).
- Who is
out? Partnerships are out, and non-dom
status (has specific rules). If a
person is currently self-employed but has complications such as joint
individual property ownership that generates rental income, being a
partner in a partnership - will mean you are outside and continue to fill
in self-assessments. Trusts/estates, LLP and Ltd are out at the
start. Specific exemptions for income from foster care and
individuals without a National Insurance Number do not need to register for MTDfITSA.
- EOPS
concept is removed from MTD for ITSA.
- Quarterly
submissions are now cumulative booking numbers for the business. The quarterly figures are cumulative per
business for the year, i.e. Q2 submission consists of all data from Q1 and
Q2. Unlike VAT, ITSA quarters are
cumulative during the year, whereas VAT is for a specific quarter.
- For
each self-employed business or property business, a quarterly per-business
submission is due to HMRC within 30 days of the quarter’s completion.
Declaration per business is still required (31 January the following
year).
- A
single crystallisation submission for the user at the year-end is
due 31 January each following year.
A yearly declaration is also required.
·
Digital links/keeping (digital records).
Can’t re-key/copy and paste. There is no requirement to use bank
feeds/PDS2 data. Some booking software firms will likely file
quarterly MTDfIT returns for each self-employed (and property)
business. Spreadsheets are an acceptable form of record-keeping. Excel
and bridging software are sufficient for the source for filing. Recording
sales can use daily sales totals for the digital source but, ideally, link to
the raw input system.
· Quarterly
submissions requiring corrections are cumulative now, so you merely correct a
mistake by adjusting in the next period/quarter.
- Starting 6 April 2026, this shall
apply to less than 750k users
- Self-assessment people with a combined income of £50k for the two
years previous need to register for MTDfITSA; the plan is to drop to £30k
the following year.
- There
is a new penalty system. Late
payment has interest penalties, basically no penalty for 15
days late, then 2% for 16-31 days and then 4% is paid after this. 4% is on the outstanding balance from the
day past due. Payment is due the following year on the 31 January. There are points, fines, and interest
charges. Penalty points for late
filing, missing four quarters in 24 months, is £200 penalty. Record
of last 24 months retained.
Summary of comparison between ITSA & SA:
|
SA |
ITSA |
|
1 SA return is done each year per person. |
Four quarterly returns via approved software per business required a
digital record link to the underlying transactions per self-employed
business. Ask HMRC to explain how to correct business
totals for the year as 1. missing
types of expenses, 2. As EOPS was removed,
assume you have 30 days to finalise business accounts from business
year-end, bringing this forward nearly eight months. Crystallisation/Finalisation using HMRC-approved software per
person, not per business. |
|
Paper submission due 31 October for the previous year. Online submissions are due 31 January – 9 months after the financial/tax
year-end. |
Approved Digital Software to submit (no paper returns). One month after each quarter, submit the quarterly cumulative return. No EOPS is due on 31 January the following
year with new rules. The Crystallisation/Finalisation/Final Declaration is also due 31 January
the following year. |
Quarterly MTDfITSA is done per business and is due one
month after the quarter period ends. Property business
quarters and year-end run in the same cycles as personal tax, starting
on 6 April and ending the following year on 5 April. As MTDfIT begins on
6 April 2026, the four quarterly submissions for the 2026-2027 tax year and
filling due dates are:
