Accounting Built for Contractors and PSCs
Contractors face challenges that general accountants rarely handle. IR35 status determinations, off-payroll working rules, Status Determination Statements, salary and dividend extraction, the 5% deemed payment allowance and umbrella company alternatives all demand advisors who understand how contractor PSCs operate.
ABM Chartered Accountants works with IT contractors, engineering contractors, management consultants, project managers and specialist freelancers across England, delivering structured financial support for contractor PSCs and individual professionals. Every Self Assessment, corporation tax and VAT return is handled accurately.
Helping Contractors Navigate IR35 and Optimise Tax
Contractors need more than basic compliance. ABM Chartered Accountants prepares contract income records, IR35 status reviews, dividend planning, VAT returns and tax forecasts, giving contractors clear visibility over after-tax income, allowable expenses and the right operating structure for each engagement.

Frequently Asked Questions
Here are answers to common questions IT contractors, engineering contractors and specialist freelancers ask about PSC accounting and tax.
What is IR35 and who decides status?
IR35 prevents disguised employment through a PSC. Medium and large clients issue a Status Determination Statement. Small clients leave it to your PSC. Inside IR35 means PAYE deductions apply.
How is contractor income best extracted?
Outside IR35 contractors typically take a small salary up to NIC threshold plus dividends from post-tax profits. This is more tax-efficient than full salary. The optimal split depends on circumstances.
What expenses can contractors claim?
Outside IR35 PSCs can claim home office costs, equipment, software, training, mileage, accommodation, professional indemnity insurance and accountancy fees. Inside IR35 engagements restrict expenses to a 5% admin allowance only.
Should contractors use the VAT Flat Rate?
Many contractors qualify as limited cost traders and pay 16.5% on gross VAT receipts. This is simpler than standard VAT accounting. The benefit depends on purchase costs and turnover patterns.
When should contractors use an umbrella?
Umbrella companies suit short inside IR35 contracts where running a PSC creates unnecessary admin. PAYE is applied automatically. Many contractors switch between PSC and umbrella depending on each contract.
Can ABM support contractors nationwide?
Yes. ABM Chartered Accountants serves contractors across England using secure cloud-based platforms, delivering specialist accounting to PSCs, sole trader contractors and umbrella users in IT, engineering and consulting.
