Consultants and freelancers — IT contractors, management consultants, marketing freelancers, project managers, and other knowledge workers — are among the most common sole traders in scope for Making Tax Digital from April 2026. Day rate earners, retained consultants, and fixed-fee project workers are all treated as self-employed sole traders for MTD, with qualifying income calculated on gross fees before any business expenses.
Your MTD qualifying income is your gross self-employment income — total fees invoiced before any business expenses (travel, software, equipment, professional subscriptions, home office). A consultant billing £60,000 and spending £15,000 on expenses has £60,000 qualifying income, not £45,000.
| Gross qualifying income (previous year) | MTD mandatory from |
|---|---|
| Over £50,000 | 6 April 2026 — mandatory now |
| Over £30,000 | 6 April 2027 |
| Over £20,000 | 6 April 2028 |
If you operate through a limited company and are caught by IR35, the deemed employment income is PAYE — it does not count towards the MTD qualifying income threshold. MTD for Income Tax applies to sole traders and landlords, not to limited company directors.
However, if you also have self-employed income outside the limited company — for example, consulting work billed personally or overseas contract fees — that income counts towards your MTD threshold as an individual.
Important: MTD for Corporation Tax (which would affect limited companies) has been cancelled by HMRC. Limited companies will not face MTD requirements.
| Scenario | Qualifying income | MTD status (Phase 1) |
|---|---|---|
| IT contractor, £600/day, 200 days, sole trader | £120,000 | Mandatory April 2026 |
| Marketing freelancer, £40,000 gross | £40,000 | Mandatory April 2027 |
| Management consultant, £55,000, via Ltd Co only | £0 (PAYE/dividends) | Not in scope |
| Part-time consultant, £22,000 + £8,000 rental | £30,000 | Mandatory April 2027 |
Expenses reduce your taxable profit but do not reduce your MTD qualifying income threshold. MTD threshold is always gross. However, you still claim expenses in your quarterly updates and Final Declaration to calculate your actual tax liability.
Allowable expenses for consultants: professional subscriptions (CIMA, BCS, APM, CIPD), software licences (Office 365, Adobe, Slack, Zoom), home office (flat rate £6/week or actual calculation), travel to client sites (not commuting), equipment (laptops, monitors — capital allowances), professional indemnity insurance, accountancy fees.

Each quarterly update is a summary of income and expenses for the quarter — not a full tax return. You submit total fees received and total allowable expenses by category. You do not need to list individual invoices or receipts in the quarterly update (though you must keep digital records of them).
Categories for consultants: self-employment income, travel and accommodation, professional services and subscriptions, home working costs, equipment and technology, marketing and advertising, other allowable expenses.
No. Qualifying income is your gross fees before agency commission or any other deductions. If an agency bills a client £100/day and pays you £80/day, your qualifying income is £80/day — the amount you receive, not the client's total cost.
Only self-employment income counts towards the MTD qualifying income threshold. PAYE employment income is excluded. If you earn £30,000 PAYE and £25,000 consulting fees, only £25,000 counts for MTD — you would not be in scope for Phase 1.
Yes. Monthly retainer fees from clients are self-employment income and count in full towards your MTD qualifying income. They are included in the quarter in which you receive them (cash basis) or earn them (accruals basis).
Yes. If you are UK tax resident, all self-employment income — from UK and overseas clients — counts towards your MTD qualifying income threshold. The income is taxable in the UK and must be declared.
MTD requires digital record keeping — you must keep records in an HMRC-approved software. Most software allows photo receipts (Hubdoc, Dext, or built-in camera capture). Paper receipts are not required if a digital copy is stored in your software.
