Your guide to personal tax in 2017/18

With each new tax year there will be changes – some positive, some perhaps not so. Either way you should understand what the new tax year means for you.

Every year it’s inevitable there will be changes to the tax system. The 2017/18 tax year is no exception with a number of changes coming into effect from April 6th 2017 including:

  • For most individuals the personal tax-free allowance increases by £500 to £11,500 (from £11,000)
  • Higher rate tax will be due on total earnings above £45,000 (from £43,000)
  • The Corporation Tax rate for small companies will be decreasing from 20% to 19%

Being aware of these changes and how they impact you is important to ensure you are making the most of new allowances and so you can meet your tax planning objectives.

Closing out the 2016/17 tax year

Don’t forget that just because the 2016/17 tax year has ended, it’s not all over on 5th April. You may still need to file personal tax returns and making sure you’re up to date is key to ensuring HMRC deadlines are met to avoid penalties.

Self Assessment Tax Returns for 2016/17 tax year

April is a great time to get ahead with 2016/17 Self Assessment Tax Returns that need to be filed before 31st January 2018.

Normally during April and May you’ll receive annual interest statements from banks or dividend vouchers / statements from your investments. Make sure you keep this information safe as it’s needed for your personal tax return. If you have a rental property, you’ll also want to be compiling your records for the tax year in readiness for your Self Assessment Tax Return.

Shortly after the start of the new tax year, when you log in to inniAccounts you’ll be able to tell us if you would like us to complete Self Assessment Tax Returns for the members of your company. Simply complete and submit the questionnaire on your dashboard along with sending us any additional information.


Due to the large number of returns we have to prepare, we complete them on a first come first served basis. Please submit the questionnaire on your dashboard and send us additional information before 31st October to benefit from our discounted fees and to avoid additional charges.

P11D – Benefits in Kind for 2016/17 tax year

If you or any of your employees have enjoyed the benefit of something paid for by your company during the tax year, a P11D must be submitted to HMRC to declare the ‘benefit in kind’. Common taxable perks include company cars, gym memberships, directors loans over £10,000 and medical insurances / treatments.

The majority of individuals won’t need a P11D. When someone does receive a benefit the company will pay class 1A National Insurance (13.8%) on the value of the benefit and the employee’s tax code will be adjusted meaning additional income tax will be deducted from their salary.

Shortly after the start of the new tax year, on your dashboard you’ll see a questionnaire about personal benefits. Take a look to see if we think anyone in your company needs a P11D and answer the few simple questions to confirm. If you need one, we can take care of it for you.


We need you to let us know by 31st May if you’d like us to take care of your P11Ds in time for the HMRC deadline.

Check and update your 2017/18 payroll

inniAccounts has been updated with 2017/18 rates and thresholds and we’ve recalculated the Employment Allowance. We’ve updated each of your tax code in line with HMRC’s instructions.

Before your first payslips of the new tax year are issued and submitted to HMRC, you should:

  • Review your company’s salaries for any automatic changes and make any changes that you require. Take a look at our updated guide on choosing a salary
  • Check your tax code has been accurately updated

If you had a salary of £10,800 – £11,200 during the 16/17 tax year, this will have been increased in your payroll to make use of the extra tax-free Personal Allowance. Salaries outside this range remain unchanged.
