# Do I Need to Do a Tax Return? 2026/27 UK Tax Guide

Determining exactly "do I need to do a tax return?" for the 2026/27 tax year requires navigating a reformed set of income thresholds. The government has aggressively targeted administrative burdens, removing hundreds of thousands of low-income traders and standard employees from the Self Assessment regime, while pushing higher earners into mandatory digital reporting.

Whether you must file a personal tax return depends on the type of income you receive, whether it breaches specific statutory allowances, and whether HMRC has formally demanded one.

## The Legal Obligation: Section 8 vs Section 7

The requirement to file a [tax return](https://www.accountingfirms.co.uk/blog/role-of-accountants-in-mergers-and-acquisitions/) stems from two distinct statutory mechanisms in the Taxes Management Act 1970 (TMA 1970).

### **1. HMRC Notice to File (Section 8)**

If HMRC explicitly sends you a notice requiring a return, you must comply. Section 8(1) of the TMA 1970 empowers HMRC to give a notice requiring a person to make and deliver a return for the purpose of establishing the amounts in which they are chargeable to [income tax](https://www.accountingfirms.co.uk/blog/all-change-furnished-holiday-lettings/) and capital gains tax.  The Court of Appeal in *Stephen Hoey v HMRC* confirmed that any person issued with a notice under section 8 must declare their income in their return, even if that income has already been accounted for under PAYE.

### **2. Duty to Notify Chargeability (Section 7)**

If you owe tax but HMRC has *not* sent you a Section 8 notice, the law places the burden on you. Section 7 of the TMA 1970 requires individuals to notify HMRC of their chargeability to income tax or capital gains tax by 5 October following the end of the tax year.  However, the Court in *Hoey* highlighted a crucial exemption:

> "The requirement to notify chargeability does not apply to a taxpayer if all of his or her income is subject to PAYE... In these circumstances the requirement to notify HMRC of chargeability to income tax under section 7 of TMA does not apply."

Therefore, if your sole source of income is a standard PAYE salary, you do not need to register for or complete a tax return unless you trigger one of the specific secondary thresholds below.

###

## PAYE Employees and General Tax Rates (2026/27)

For the 2026/27 tax year, the government has maintained the freeze on baseline income tax thresholds. The Personal Allowance remains at £12,570, and the basic rate limit is fixed at £37,700.  This combination creates a higher rate threshold of £50,270.

The statutory default rates of income tax for 2026/27 are:

- **Basic rate:** 20%
- **Higher rate:** 40%
- **Additional rate:** 45%

Following the removal of the £100,000 mandatory filing threshold in April 2025, high-earning PAYE employees no longer automatically need to file a tax return purely based on their salary level, provided their employer correctly operates PAYE and they have no untaxed secondary income.

###

## Self-Employment and Property Income (The £3,000 Rule)

If you generate trading [income or property rental](https://www.accountingfirms.co.uk/blog/friends-without-benefits/) income, you must test your gross receipts against two distinct thresholds for the 2026/27 tax year.

- **The £1,000 Trading Allowance:** Section 783AD(1) of the Income Tax (Trading and Other Income) Act 2005 (ITTOIA 2005) provides an individual trading allowance of £1,000.  If your gross trading income is below £1,000, it is entirely tax-free and requires no reporting.
- **The £3,000 Reporting Threshold:** As part of its modernisation roadmap, the government increased the Income Tax Self Assessment (ITSA) reporting threshold for gross trading and property income to £3,000.

**Application to the facts:** If an individual earns £2,500 in gross trading income from a side hustle, they exceed the £1,000 tax-free allowance under section 783AD ITTOIA 2005, meaning the £1,500 excess is technically taxable.  However, because the gross income remains below the new £3,000 reporting threshold, the taxpayer is taken out of the Self Assessment return system.  The liability can instead be settled via a simplified reporting mechanism or a PAYE tax code adjustment.

###

## High Income Child Benefit Charge (The £60,000 Trigger)

If you or your partner claim Child Benefit, your income level may mandate a tax return. The High Income Child Benefit Charge (HICBC) applies when a taxpayer's [adjusted net income](https://www.accountingfirms.co.uk/blog/childcare-benefit-and-the-tax-charge/) exceeds the statutory threshold.

For the 2026/27 tax year, the HICBC starting threshold is £60,000.  The charge is calculated on a tapered basis between £60,000 and £80,000. Legislation amends the formula so that the charge withdraws 1% of the Child Benefit for every £200 of income above £60,000.

**Application to the facts:** If a taxpayer has an adjusted net income of £70,000 and claims £2,000 in Child Benefit:

1. Income above threshold: £70,000 - £60,000 = £10,000.
2. Taper calculation: £10,000 / £200 = 50%.
3. HICBC liability: 50% of £2,000 = £1,000. The taxpayer *must* complete a tax return to report and pay this £1,000 charge.

###

## Capital Gains and Dividends

If you dispose of assets or receive investment income, you must file a return if you breach the following annual allowances:

- **Capital Gains Tax (CGT):** The Annual Exempt Amount is strictly capped at £3,000 for individuals.  If your net chargeable gains for the year exceed £3,000, you must file a tax return.
- **Dividends:** The tax-free dividend allowance remains at £500. Dividend income exceeding this limit requires a return so HMRC can apply the relevant [dividend tax rates](https://www.accountingfirms.co.uk/blog/interesting-dividends/).

## Making Tax Digital for ITSA (The £50,000 Mandate)

If you have self-employment or property income, answering "do I need to do a tax return?" also dictates *how* you must file it.

From 6 April 2026, the Making Tax Digital (MTD) for Income Tax Self Assessment mandate legally requires sole traders and landlords to use MTD-compatible software if their total qualifying income exceeds £50,000.  If you breach this £50,000 threshold, you can no longer submit a traditional annual Self Assessment return; instead, you must maintain digital records and submit quarterly digital updates to HMRC, followed by a final end-of-year declaration.

For completeness, the government has legislated that this MTD threshold will lower to £30,000 from April 2027, and subsequently to £20,000 from April 2028, pulling progressively more taxpayers into the quarterly digital reporting regime.

## Summary of 2026/27 Filing Requirements

| Taxpayer Element | Statutory Event / Provision | 2026/27 Threshold | Consequence |
| --- | --- | --- | --- |
| **PAYE Employee** | s 7 TMA 1970 (Notification) | No arbitrary limit | Exempt from notifying chargeability if all income is taxed at source via PAYE. |
| **Sole Trader / Landlord** | HMRC Roadmap Reporting Rule | £3,000 (Gross Income) | Below £3,000: No Self Assessment return required. |
| **Child Benefit Claimant** | s 681B ITEPA 2003 (HICBC) | £60,000 (Adjusted Net Income) | Must file a return to pay the charge; benefit fully withdrawn at £80,000. |

| **Qualifying Business/Landlord** | MTD for ITSA Mandate | £50,000 (Qualifying Income) | Must discard paper returns and use software for quarterly digital updates from 6 April 2026. |
| **Any Individual** | s 8 TMA 1970 (Notice to File) | N/A | Must legally file a return if HMRC issues a formal section 8 notice, regardless of income level. |
