Personal Tax Compliance

Annual self assessment compliance run accurately on time
and with senior review

Speak to the team

A personal tax return looks straightforward until it is not. For individuals with multiple income sources, capital gains, business interests, foreign elements, trusts or other complex features, the compliance work requires genuine care – and the consequences of an error or a missed position are harder to manage now than they were even a few years ago as HMRC’s data-matching capabilities and appetite for enquiry have both increased.

The penalties for late or incorrect returns have tightened. HMRC enquiries are more frequent. The introduction of Making Tax Digital for Income Tax is changing the way the work is delivered for unincorporated landlords and sole traders.

Our personal tax compliance service is built around a defined annual timetable, senior review and a named team that stays with you year after year.

The work is delivered well in advance of the statutory deadline and the position is reviewed for planning opportunities as part of the cycle.

How we deliver personal tax compliance process

The same named team handles your return year after year. The knowledge of your position, the elections previously made and the planning previously considered all stays in the relationship.

Where the return raises a planning question, we explore it as part of the cycle rather than waiting for a separate conversation.

Our expertise covers

  • Self assessment preparation and filing
  • Multiple sources of income and complex returns
  • Capital Gains Tax computations
  • Property income, including portfolio landlords
  • Foreign income and gains, including the post-April 2025 rules
  • Partnership returns
  • Trust returns and beneficiary reporting
  • Non-resident tax returns
  • Pension annual allowance and tapering calculations
  • Making Tax Digital for Income Tax

Where your return has features that require specialist input, such as crypto assets, trust interactions, complex employment-related securities or international elements, the relevant specialist within the firm joins the compliance team for that part of the return.

What you can expect
from our compliance team

Three principles run through the work:

Delivered to a defined timetable

The annual cycle runs to fixed dates well ahead of the filing deadline. The return is filed in good time and any payments are clear in advance.

Continuity year to year

The same named team handles your compliance year after year. The cumulative understanding of your position supports the work being done well.

Planning surfaced from the work

Where the return exposes a planning point, such as a relief becoming available, an election worth making or a position worth reviewing, we put it in front of you with the analysis. Compliance and planning are joined at the point of the work.

Individuals move their personal tax compliance to us because they want a service that runs reliably in the background – accurate, timely and backed by senior review – with a team they trust to flag the planning points when they arise rather than waiting to be asked

Frequently Asked Questions faq

What does Making Tax Digital for income tax mean for us?

From April 2026, individuals with combined income from self-employment and property above the threshold will need to keep digital records and submit quarterly updates to HMRC alongside the annual final declaration. The threshold reduces over the following years. We are working with affected clients on the practical implementation including software, record-keeping and the quarterly cycle.

What happens if I file late?

Late filing triggers an initial £100 penalty with further penalties accruing if the delay continues. Interest is charged on tax paid late and surcharges apply for prolonged delays. Our cycle is designed so the return is filed well ahead of the deadline. Where late filing is unavoidable, for example because of late source data, we manage the position with HMRC and minimise the consequences.

Can you handle our compliance alongside our existing financial adviser?

Yes. That is a common arrangement. Where you have a financial adviser handling investments and we handle the tax compliance, we co-ordinate so the information needed for the return is collected efficiently and the planning advice is consistent. We work alongside existing professional teams routinely.
