The £50,000 MTD ITSA threshold catches more London Uber drivers than most realise because the test runs on gross fares received, not on the net income after expenses. A typical full-time London PCO driver pulling £900-£1,200 per week of gross fares is at £47,000-£62,000 of annual gross income, sitting squarely on the threshold. Multi-apping (Uber plus Bolt plus Deliveroo, or any combination) combines for the test. Knowing whether you are in or out from April 2026 is the difference between starting quarterly reporting now or carrying on with the annual Self-Assessment.
This piece walks the threshold test for PCO drivers, the gross-fares definition, the multi-app combining rule, and the partial-year scenarios common for new drivers. Sister pieces in [the MTD ITSA Uber driver hub](/insights/mtd-itsa-uber-driver-2026-mandate/) cover [the quarterly submission mechanics for drivers on the road](/blog/submit-quarterly-mtd-updates-on-the-road/) and [the best MTD software for PCO drivers](/blog/mtd-software-pco-quickbooks-xero-freeagent/).
How HMRC tests the threshold for drivers
The £50,000 threshold is gross qualifying income from self-employment and property combined, measured against the 2024-25 Self-Assessment return on file. For a typical Uber or PCO driver, the relevant figure is the gross fares total on the SA103 self-employment supplementary page, before deducting platform fees, fuel, insurance, MOT, finance, or any other allowable expense.
A driver with 2024-25 figures of £52,000 gross fares and £20,000 of allowable expenses (giving £32,000 of taxable profit) is inside MTD because the test ignores the expenses. The profit figure is irrelevant for the threshold test; what matters is what arrived in the driver's payment account from Uber, Bolt, or whichever platform.
What counts as gross fares
- Total fare collected from passenger before Uber/Bolt/other platform commission.
- Tips received via the platform.
- Cleaning fees, cancellation fees, and surge multipliers.
- Promotional bonuses paid by the platform.
- Tolls paid by passengers passed through.
- Excluded: VAT on the fare if VAT-registered; only the net-of-VAT fare counts.
- Excluded: any reimbursements that are not income (e.g., congestion charge passed through).
Multi-apping combining
A driver working across Uber, Bolt, Free Now, Addison Lee, and Deliveroo combines all platforms for the threshold test. The Self-Assessment return treats the activity as a single self-employment business (typically "private hire driver" or "delivery driver" depending on primary activity), with one set of accounts summing all platforms. If the combined gross is above £50,000, the driver is inside MTD regardless of how the income is split between platforms.
Drivers who run separate sole-trader operations for each platform (rare but seen) test each separately, but the practical reality is that almost all multi-app drivers run a single self-employment. The single-self-employment approach is also simpler operationally and is what HMRC expects.
The threshold reduction schedule
A London full-time PCO driver typically grosses £45,000-£70,000 per year. The £50k threshold catches most of the upper half of the distribution from April 2026. The £30k threshold from April 2027 catches almost all full-time London drivers and a significant share of part-time drivers. By April 2028, MTD is the universal regime for working drivers.
Partial-year scenarios
A driver who started in October 2024 has only 6 months of 2024-25 income (perhaps £25,000 of gross fares from a £50,000-annualised pace). They are outside MTD for April 2026 entry. The 2025-26 return, filed January 2027, will show a full year above threshold, putting them inside MTD from April 2027 onwards. The lag means a fast-growing driver may be outside MTD for one year longer than their actual income would suggest.
The HMRC notification letter
HMRC writes individually to drivers it identifies as inside MTD from April 2026, based on the 2024-25 Self-Assessment data. Letters typically arrive between October 2025 and February 2026. The letter confirms the entry date and provides initial guidance. Drivers who filed 2024-25 late may not receive the letter even if inside the threshold; the legal obligation still applies.
What goes in a quarterly update for a driver
A driver's quarterly update under MTD ITSA summarises gross fares received plus the broad expense categories: motor expenses (fuel, insurance, MOT, finance, depreciation or mileage), platform fees, professional fees, other allowable. The data sits underneath in the driver's MTD-compatible software, with bank feed integration covering the platform payments and fuel purchases.
Should I voluntarily enter MTD if below threshold?
For drivers approaching £50k of gross fares, voluntary entry from April 2026 avoids the disruption of a mid-year switch when the threshold is crossed. The marginal admin cost is small (£10-£20 per month of software, plus accountant fees that would already apply). For drivers materially below threshold (£20k-£35k of gross fares), voluntary entry is rarely worthwhile; the next threshold reduction will catch them in due course.
What about the VAT side?
Most PCO drivers are below the £90,000 VAT threshold and not VAT-registered. MTD ITSA applies regardless of VAT status. For the small minority of high-earning drivers above the VAT threshold (typically multi-vehicle operators), both MTD VAT and MTD ITSA apply, with separate filings on different schedules. See also [the 2026 Private Hire VAT changes](/insights/private-hire-vat-changes-january-2026/) for the wider VAT reform context.
Practical next steps for affected drivers
Can my accountant submit on my behalf?
Yes, under the new MTD agent authorisation. Most accountants serving the PCO and ride-hail driver community submit quarterly updates and the Final Declaration on the driver's behalf, with the driver reviewing and approving. The fee differential between annual Self-Assessment and quarterly MTD ITSA is typically £200-£400 per year for a typical PCO driver. Most drivers find the agent-led model materially less stressful than self-managing.
