VAT Flat Rate Scheme Calculator for Architect, civil and structural engineer or surveyor
For sole-practice and small-firm architects, civil and structural engineers, building surveyors, and property surveyors registered for VAT.
Why this matters for architect, civil and structural engineer or surveyor
The 14.5% FRS rate covers architects, civil and structural engineers, and surveyors. Software (CAD, BIM, Revit, AutoCAD) is the dominant non-payroll cost — and being SaaS-licensed counts as services for LCT purposes, leaving most practices over the LCT line.
A sole-practice architect billing £85,000 net might reclaim £500–£1,200 of input VAT (CAD subscriptions, surveys, occasional plotter / hardware). FRS at 14.5% beats Standard only when input VAT is under ~£2,210 (2.6% of net).
Limited Cost Trader trap
High risk — most caughtCAD/BIM subscriptions, professional body fees, indemnity insurance, and printing services all count as services. Plotters, ink, paper, and physical equipment are goods — but rarely add up to enough to clear the 2%/£1,000 threshold for a digital-first practice.

Frequently asked questions
I subcontract structural calcs to other engineers. Are those services or goods?
Sub-consultant fees are services in your hands. They count toward your VAT-inclusive turnover (output) but do not help you meet the LCT goods test. If subcontracting is a large share of your costs you almost certainly hit the 16.5% Limited Cost rate.
Are surveying instruments (theodolite, GPS units, drone) goods that count for the LCT test?
Yes — physical equipment used exclusively for the business is goods. But capital items (single purchases that go on the balance sheet) are explicitly excluded from the LCT goods test. Smaller items under the capitalisation threshold do count.
What is the FRS rate for architect, civil and structural engineer or surveyor?
HMRC publishes a flat rate of 14.5% for "Architect, civil and structural engineer or surveyor" under the VAT Flat Rate Scheme.

If your business is classed as a Limited Cost Trader (goods spend below 2% of VAT-inclusive turnover or below £1,000/year), the rate becomes 16.5% regardless of sector.
What is the break-even input VAT for architect, civil and structural engineer or surveyor on FRS?
