Over 16 million people have set up their PTA and enjoy the real benefits of instant accessing their personal tax data.

The personal tax account (PTA) is effectively Making Tax Digital for individuals. Ultimately, HMRC’s intention is to develop a full range of services to allow taxpayers to self-serve without having to contact HMRC by phone or post.

Although developments to the PTA have temporarily stalled because of the demands on HMRC resources created by Brexit, there are already many services that individuals can access via their PTA. These include:

  • reviewing PAYE coding notices
  • filing self-assessment returns
  • obtaining state pension forecasts
  • updating tax credits and child benefit claims
  • making marriage allowance transfers


Any taxpayer can set up their PTA but the service is particularly valuable for employees as it enables them to check that HMRC holds the correct information about their employment, and to review and request amendments to PAYE coding notices.

Checking whether HMRC holds the correct employment details is particularly useful as RTI data can contain errors: mismatches and duplicated payroll records do occur. In such cases, the individual’s form P60 or P45 is the only proof of their income, tax deductions and national insurance contributions for the period. Using their PTA, employees can check that the details of their employment income held by HMRC are correct and resolve any discrepancies.

Estimated income

Within the PAYE section, an individual can also check whether HMRC’s estimates of any other income are reasonable. Following the introduction of dynamic coding, where HMRC updates coding notices in-year as a result of certain triggers, it is very important that HMRC’s estimates of the taxpayer’s total income for the year are reasonable.

The dynamic coding system uses the total estimated income figure to recalculate tax codes so, if the estimated total income is unreasonable, the taxpayer will receive an inappropriate code and end up paying too much or too little tax.

Individuals can apply for adjustments to be made to their estimated income through their PTA, without having to call HMRC.

State pension and NIC records

Probably the first thing most people do (okay, it was the first thing that I did) on creating a PTA though is to check their state pension entitlement. It is possible to see your full history of NI contributions at the click of a button – far quicker than writing off for a forecast. It is easy to see if there are any years where contributions are missing, or if anything looks odd.

Since this data is not necessarily reconciled to other HMRC systems, it is important to check that your history of contributions is what you expect. Again, it is far better to resolve any discrepancies now, than to find out years or decades down the line that your state pension is less than you expected.
