MTD for Dentists and Dental Associates —
NHS, Private, and the ESA Problem
Use your gross self-employed fees before lab bills, associate deductions or ESA costs are deducted.
If you are a self-employed dental associate, a practice principal, or a hygienist working under an Expense Sharing Agreement (ESA), Making Tax Digital applies to you individually — not to the practice collectively. This is the most common source of confusion for dental professionals in 2026, and the rules have specific implications depending on whether you earn NHS fees, private fees, or both.
MTD Threshold for Dental Professionals
Your qualifying income for MTD is your gross self-employment income — this means gross fees received before any practice expenses, lab fees, materials, or ESA cost-sharing deductions. For dental associates:
| Income over (previous tax year) | MTD mandatory from | Estimated associates affected |
|---|---|---|
| £50,000 | 6 April 2026. Live | ~15,000 |
| £30,000 | 6 April 2027 | ~25,000 additional |
| £20,000 | 6 April 2028 | ~10,000 additional |
A dental associate earning £65,000 gross in NHS and private fees in 2024–25 is mandatory since April 2026, regardless of how much of that gross was absorbed by lab costs, materials, or ESA overhead contributions.
The ESA Problem — Why Standard Software Fails
Most dental practices operate under an Expense Sharing Agreement (ESA). Each associate is legally self-employed but shares overhead costs through the ESA. HMRC treats each associate as an individual sole trader for MTD purposes — each must maintain their own digital records and submit their own quarterly updates.
The problem is that most HMRC-approved software (QuickBooks, FreeAgent, Xero) is built for either a sole trader with their own expenses, or a practice with employees. ESA practices do not fit neatly into either model because the expense allocation happens at practice level, not at individual associate level.
Practical solution: Each associate needs their own software subscription. The practice manager or accountant reconciles ESA cost allocations at year-end for the Final Declaration. QuickBooks Sole Trader or FreeAgent work well for associates who receive a clean income figure from the practice management system.
NHS Fees vs Private Fees
Both NHS fees and private fees count as qualifying income for MTD. There is no distinction in the MTD rules between NHS contract income (UDA payments) and private patient fees — both are gross self-employment income.
Associates paid through a practice payroll for NHS work and receiving private fees separately should check whether their NHS income is truly self-employed (on a self-employed basis contract) or PAYE employment. If NHS fees are PAYE — they do not count towards the MTD threshold. Verify your contract type with your practice principal.
Hygienists and Therapists
Self-employed dental hygienists and therapists are treated identically to dental associates. If your gross self-employment income from all practices combined exceeds the threshold, you are in scope for MTD. Hygienists working at multiple practices must aggregate all self-employment income — not just income from a single practice.

Key Deadlines for Dental Associates
| Deadline | Date | What you must do |
|---|---|---|
| Q1 quarterly update | 7 August 2026 | Submit income and expenses for 6 April – 5 July 2026 |
| Q2 quarterly update | 7 November 2026 | 6 April – 5 October 2026 |
| Q3 quarterly update | 7 February 2027 | 6 April 2026 – 5 January 2027 |
| Q4 quarterly update | 7 May 2027 | 6 April 2026 – 5 April 2027 |
| Final Declaration | 31 January 2028 | Full year 2026–27, replaces Self Assessment |
The soft landing for 2026–27 means no penalty points for late quarterly updates in Phase 1's first year — but late payment interest still applies from day one.
Frequently Asked Questions
Does NHS income count towards the MTD threshold?
Yes — gross NHS fees from self-employed associate contracts count as qualifying income. If your NHS fees are processed as PAYE employment income through a practice payroll, they do not count. Check your contract basis with your practice principal.
I work at three practices — do I combine all income for the MTD threshold?
Yes. You must aggregate gross self-employment income from all dental practices where you are self-employed. If your combined gross fees across three practices exceed £50,000, you are in scope from April 2026.
Does my ESA mean I am in a partnership for MTD?
No. Expense Sharing Agreements do not create a partnership for MTD purposes. Each associate is an individual sole trader. HMRC is explicit on this. Confirmed in BHP's April 2026 guidance for dental practices.
What counts as gross income for a dental associate?
Gross fees received from the practice — before any deductions for lab costs, materials, ESA cost shares, or practice overheads. The gross figure is what appears on your practice statement before any deductions, not your net take-home.
Do I need to be registered for MTD now?
Yes. If you had qualifying income over £50,000 in 2024–25, you should already be registered and using HMRC-approved software. Your first quarterly update, for Q1 (6 April to 5 July 2026), was due 7 August 2026. Your next update, covering 6 April to 5 October 2026, is due 7 November 2026.
