Making Tax Digital Portsmouth
ICAEW chartered accountants providing Making Tax Digital compliance for Portsmouth businesses and landlords. We specialise in MTD for naval defence contractors, Solent marine trades, and student property investors across Portsmouth and Gosport. Free consultation for all Portsmouth businesses.
Why Portsmouth Businesses Need Specialist MTD Support
Portsmouth is the home of the Royal Navy and the UK's premier naval city. The economy revolves around defence procurement and engineering at HMNB Portsmouth, a thriving Solent marine industry, the Gunwharf Quays retail and leisure district, a large University of Portsmouth student rental market, and cross-Solent ferry operations connecting to the Isle of Wight and continental Europe. Each sector brings specific MTD compliance needs that require more than generic accounting knowledge.
Naval Defence Supply Chain
The defence supply chain is particularly complex for MTD. Contractors range from large tier-one suppliers like BAE Systems to individual CIS-registered tradespeople doing refit work on warships.
Multi-Contract CIS Complexity
Naval contractors often hold multiple contracts simultaneously, receive CIS deductions from different principal contractors, and need to reconcile complex payment structures within MTD's quarterly rhythm.
Risk of Penalties & Drag
Getting CIS and MTD wrong means penalty points, overpaid tax, or severe cash flow problems that can cripple a small defence subcontractor operating under tight margin conditions.
Student Rental Market
With a large University of Portsmouth student rental market across Southsea, Milton, and Fratton, landlords with 3+ properties face multi-property tracking and Section 24 MTD ITSA rules.
Solent Marine & Ferry Trade
Cross-Solent transport, marine engineering, boat sales, and Gunwharf Quays retail face complex mixed-rate VAT treatments and international service zero-rating requiring exact software setup.

Portsmouth Case Study: Multi-Contract Naval Contractor Saves £6,100
A self-employed marine pipefitter working at HMNB Portsmouth held contracts with three different principal contractors simultaneously. Turnover was approximately £82,000, with CIS deductions being taken at 20% by all three contractors, and standard VAT registration. His previous accountant filed annual Self Assessment but had no CIS reconciliation process and had never assessed Gross Payment Status eligibility.
- Applied for Gross Payment Status (approved within 5 weeks, eliminating 20% cash flow drag on future invoices)
- Reconciled CIS deductions from 3 contractors and reclaimed £2,800 in over-deducted tax from HMRC
- Switched from simplified flat rate vehicle expenses to actual cost method (£2,100 additional annual claim)
- Claimed Annual Investment Allowance (AIA) on specialist tools and safety equipment (£1,200 per year)
- Configured FreeAgent with separate tracking for each principal contractor for seamless MTD filing
Result: £6,100 annual saving (£2,800 CIS reclaim + £2,100 vehicle + £1,200 tools) plus GPS eliminating cash flow drag. Software cost: £0. Our fee: £95 per month.
