If you are self-employed in the UK you can pay for your hearing aids through your business as an expense. This could result in significant savings especially if you are a higher tax payer.
If you are VAT registered you can also claim back the VAT.
If your accountant or bookkeeper questions your request to place your hearing aids through the business please refer them to HMRC guidelines.
“EIM21846 – Particular benefits: exemption for equipment or services provided to employees with a disability
Section 316 and Section 210 ITEPA 2003 and S.I.2002 No.1596
The provision of equipment and services solely to carry out the duties of the employment, where private use is not significant, is exempt from a tax charge under Section 316 ITEPA 2003 (see EIM21610). For employees with a disability, special rules in Regulations (S.I.2002 No.1596) laid under powers in Section 210 ITEPA encourage employers to provide equipment and services to assist them to work. Normally if an employee also used the equipment or services for significant private use this would represent a taxable benefit but these Regulations ensure that no tax charge arises on this benefit when provided to an employee with a disability, even if the employee uses the equipment both in work and outside work (for example, a wheelchair or a hearing aid), and private use is significant.”
