IR35 Public Sector Changes for Contractors and Freelancers

Following the Autumn Statement, what does the IR35 public sector changes mean for contractors? Our easy to read FAQ will hopefully answer some of those key questions. 

1. Who is affected by the IR35 legislation changes?

The new legislation, referred to by HMRC as the ‘off-payroll working in the public sector: reforming the intermediaries’ legislation’ affects public sector bodies, but that does not necessarily mean that contractors will naturally fall within IR35. These changes apply to public authorities who hire off-payroll contractors. A public authority means a public authority as defined for the Freedom of Information Act 2000 and the Freedom of Information (Scotland) Act 2002. For example, areas that could be affected include: 

  • Government departments
  • The BBC
  • Channel 4
  • The Bank of England
  • The NHS
  • Police and Fire authorities

2. What has prompted these changes?

There have been a series of high profile media stories on the growing use of contractors in the public sector.

HMRC is convinced that a large proportion of contractors, are disguised employees. This new legislation change, means the way which IR35 is enforced in the public sector, shifts the responsibility away from HMRC and onto the end client i.e. the public sector body.

Therefore, the contract should already be pre-determined before the contract comes over to the agency.

3. When will the changes come into force?

The changes will come into force from 6th April 2017. They will only apply to contractors working for public sector organisations. Instead of contractors determining their IR35 status, the government now wants public sector organisations, to determine the IR35 status for them.

If a contractor is deemed to be inside IR35, the engager, i.e. this could be the public sector or the agency, will deduct income tax and National Insurance as they would for employees.

4. How will the public sector organistations and agencies decide if a contract is inside or outside of IR35?

HMRC's online IR35 tool. The tool will ask users a series of questions about the nature of a contractor’s engagement, and determine their IR35 status based on the answers given. HMRC have now published the IR35 tool. Click here to use this service.

5. What if my contract is ‘deemed outside IR35’? Can I still be deemed an employee?

Yes. If the contract does not reflect the reality of the working practices, then it offers no defence. This has always been the case but in practice is very difficult to enforce. By shifting the burden to the end client and asking questions about the day-to-day reality of the engagement, HMRC is hoping to arrive at a solution which is quick and inexpensive to administer.

6. Is there a risk that the online IR35 tool will be biased?

Organisations which represent contractors, including SJD Accountancy, have raised this concern. As such, we will be working with HMRC to test the tool and ensure that it accurately reflects workers’ employment status. As and when more information is available we will be sure to share this.

7. Is it still beneficial for contractors to work in both public and private sectors?

Yes, it is still beneficial for the contractor. This is dependent on the length of the public sector contract and each individual’s personal circumstances. We would always ask clients to speak to their accountant for a more comprehensive understanding on this.

8. If you are a Limited Company working inside IR35, is this still a beneficial option?

Working through a Limited company whilst inside IR35 still comes with the following benefits:

  • Contractors can still register for the flat rate VAT scheme whist working inside IR35 saving more of their hard-earned money throughout the year.
  • Contractors will be no worse off using an umbrella company over a limited company as fees are often the same, in fact some umbrella companies charge more than accountancy fees.
  • Once a limited company is set up contractors can then trade through it for other assignments which might be outside IR35.
  • With a limited company, all payment is paid directly into the company’s bank account. However, with an umbrella company the money flows to them and then to the contractor. A few years ago an umbrella called Prosperity 4 went bankrupt and the contractors didn’t get paid.

SJD Accountancy provides Umbrella Company Services to contractors and freelancers through our sister company, Parasol. For more information please call 0800 470 1549 or email

9. Are the underlying criteria of the IR35 test changing?

The criteria for determining whether a contract falls inside or outside IR35 will remain the same. For example, if a worker is under the supervision, direction and control of the end client, they will be deemed inside IR35.

The only thing changing is that the responsibility for determining the contractors IR35 status is moving from the contractor/PSC to the public sector body.

10. Is this part of a wider crackdown on non-compliance with IR35?

Determining whether a contractor passes or fails IR35 requires a detailed knowledge of their working arrangements, not just the contract. Hirers are ideally placed to know the details of their contractors’ working arrangements, which is why HMRC is keen to shift responsibility and liability to them.

11. How will the public sector changes affect contractors take home pay from 2017?

Below you will find an average take home calculation for those working inside IR35, outside IR35 or through PAYE Umbrella. All contracts are different, so we always advise that should a more detailed breakdown be required please speak to your accountant.


  Outside IR35 Inside IR35 PAYE/Umbrella
Daily contract value £400 £400 £400
Take home * £57,890.46 £55,785.88 £54,927.51






  Outside IR35 Inside IR35 PAYE/Umbrella
Daily contract value £400 £400 £400
Take home * £58,591.92 £55,312.93 £55,239.51




*Please note, the above calculations are just an estimate and are based on 230 working days, some basic expenses and the contractor being on the flat rate VAT scheme (including 1% discount).

So contrary to much uncertainty in the market, as a contractor, you may be better working inside IR35 through your own limited company. For more details on going Limited, take a look at our easy to read guide: Advantages and Disadvantages of going Limited
