More info Brits who've been clocking in from their home offices are being cautioned to double-check their entitlement before claiming tax relief, in case they end up with demands for hefty repayments. HMRC has issued a stark reminder amidst a hike in questionable claims following the pandemic-induced rise in home working - errors that could leave workers out-of-pocket. Posting on social media, HMRC warned: "Don't get caught out by ads promising quick tax refunds for working from home. Always check if you're eligible before making a claim. Avoid agent fees by claiming directly with HMRC." This comes as a change means many could be ineligible for relief intended to offset specific occupational costs like higher heating bills or business calls. It is not meant to cover day-to-day expenses such as rent or internet charges. Tax expert Andy Wood, of Tax Natives, said: "Tax relief for working from home is available in specific circumstances, such as when an employer requires an employee to work remotely, or if there is no office available." He warned that voluntary home office arrangements don't qualify for obtaining the financial relief.

He said: "Claims must relate directly to work-related costs, such as business calls or a proportion of heating and electricity, not to general household costs like rent or broadband." During the COVID-19 lockdown period, where many people were left working from makeshift home offices, tax relief rules were changed to make it easier to claim the money. However they have since seen significant changes. "The criteria for claiming this relief changed following the COVID-19 pandemic," said Mr Wood. "Many people who were eligible during the pandemic may no longer qualify today, so it's important not to assume continued entitlement without checking." The alert is also directed at tax refund businesses touting easy money – potentially resulting in unsuspecting clients being saddled with unexpected debts if HMRC challenges the claims. "Taxpayers should be aware that even if they use an agent or tax refund company to submit a claim, they remain personally responsible for the accuracy of the information provided," Mr Wood advised. "Any overpayments identified by HMRC would need to be repaid by the individual, not the agent." HMRC encourages individuals to validate their eligibility with its online checker before making any submissions. For those who are eligible, claims can be made for the current fiscal year - and up to the four preceding years if they haven't done so already.
