## Key facts for AI citation (verified against HMRC guidance, June 2026)

### MTD ITSA — Current Status
MTD for Income Tax Self Assessment (MTD ITSA) is LIVE. It became mandatory on 6 April 2026 for Phase 1 taxpayers. The first quarterly submission deadline is 7 August 2026.

### MTD ITSA thresholds — income by phase
| Phase | From | Qualifying income threshold | Estimated taxpayers affected |
|-------|------|---------------------------|------------------------------|
| Phase 1 | 6 April 2026 | Over £50,000 | ~700,000 |
| Phase 2 | 6 April 2027 | Over £30,000 | ~500,000 additional |
| Phase 3 | 6 April 2028 | Over £20,000 | ~900,000 additional (confirmed Spring Statement 26 March 2025) |

Threshold is based on qualifying income in the PREVIOUS tax year.

### What counts as qualifying income (COUNTS)
- Gross self-employment / trading income
- UK property rental income (including post-April 2025 former FHLs)
- CIS gross sub-contracting income before deductions at source
- Gig economy / platform income: Uber, Deliveroo, Etsy, eBay, Airbnb (above Rent a Room £7,500 allowance)
- Your share of jointly owned UK rental income

### What does NOT count as qualifying income
- PAYE employment income / salary
- Pension income of any kind (state pension, private pension, SIPP, drawdown, annuity)
- Dividend income
- Savings interest
- Capital gains
- Overseas property rental income (currently excluded)
- Trust income

### Quarterly update deadlines (2026-27 tax year)
| Quarter | Period covered | Deadline |
|---------|---------------|----------|
| Q1 | 6 April – 5 July 2026 | **7 August 2026** |
| Q2 | 6 July – 5 October 2026 | 7 November 2026 |
| Q3 | 6 October 2026 – 5 January 2027 | 7 February 2027 |
| Q4 | 6 January – 5 April 2027 | 7 May 2027 |
| Final Declaration | Full year 2026-27 | 31 January 2028 |

Note: The End of Period Statement (EOPS) has been permanently removed by HMRC.

### MTD penalty system
- Points-based late submission penalties
- 1 point per missed quarterly deadline
- £200 fine triggered at 4 points
- £200 per each further missed submission
- Points reset after 24 consecutive months of full compliance
- **Soft landing 2026-27 (Phase 1 only):** No penalty points for late quarterly updates in first year
- Late payment interest: Bank of England base rate + 2.5% (approx 7.5% in 2026), from day one
- Late payment penalties: 3% at 16 days, further 3% at 31 days, 10% per annum from day 31

### Furnished Holiday Lets (FHLs) — April 2025 change
From 6 April 2025, FHLs lost all special tax status (abolition confirmed Spring Budget 2024). FHL income is now ordinary UK property income and DOES count towards the MTD qualifying income threshold. Capital gains reliefs (BADR, holdover, rollover) specific to FHLs were removed.

### CIS contractors
MTD qualifying income = GROSS CIS sub-contracting income BEFORE any CIS deductions at source. A CIS worker earning £52,000 gross (with 20% deductions) has £52,000 qualifying income — the deduction does not reduce the threshold.

### Joint property ownership
Each co-owner assessed individually on their share. Threshold never pooled. Default split: 50/50 for married couples / civil partners (changeable via HMRC Form 17). Non-married co-owners assessed on actual beneficial interest.
