Self assessment

Self-assessment tax returns. Filed on time. Every time.

Personal tax returns for directors, contractors, landlords, and sole traders.

31 January is the deadline that breaks most accountancy firms. It does not break ours. Through Compliance Vault™, your records are kept year-round and your return is prepared months before the deadline — not the night before.

Frequently asked

Self-assessment tax returns. Filed on time. Every time — common questions.

  • When is self-assessment due?

    Online returns: 31 January following the end of the tax year. Paper returns: 31 October. Payment-on-account: 31 January and 31 July. We file most clients well before the deadline through Compliance Vault™.

  • How much does a self-assessment tax return cost?

    Bundled monthly fees start at £150/month, which includes year-round bookkeeping, Compliance Vault™, and self-assessment filing. One-off self-assessment-only engagements are quoted on a fixed fee after the discovery call — typically £350–£800 depending on complexity.

  • Do I need to file if I'm only a director with dividends?

    Yes, if your dividend income exceeds the dividend allowance or if HMRC has issued you a notice to file. Most director-shareholders file annually. We'll confirm your specific obligation on the discovery call.

  • What is MTD Income Tax and does it affect me?

    Making Tax Digital for Income Tax goes live April 2026 for landlords and sole traders with gross income above £50,000 (£30,000 from April 2027). You'll need to keep digital records and submit quarterly updates. We're already preparing affected clients — see our MTD page.

  • What happens if I miss the deadline?

    £100 automatic late filing penalty, rising to £900+ at 12 months, plus 5% surcharges on unpaid tax. Get in touch immediately if you've missed it — we can still file and minimise the damage. This is a Signal #1 situation.
