Claiming expenses for phone bills when doing your taxes can seem a little complicated at first, but it doesn’t have to be.  SimpleTax’s offer a hassle-free approach to completing your tax return, including everything you need to know about claiming phone bill expenses. Can I claim? Yes, but only for business-related calls. Conditions This depends on whether your business is registered to your personal address, or to another premises such as an office complex.  In the latter case, providing all the calls you make are for business use only, you can claim your phone bills as an expense when doing your taxes.  If you work from home and do not have a separate line for business and personal calls, you will need to look at what percentage of the calls you make are specifically for your business, and claim only for these calls. On SimpleTax In both of the above scenarios, SimpleTax makes it incredibly easy to claim phone bills as an expense on your tax return. Under Self-Employed Expenses, choose either "Use of Home as an Office" if your business is registered to your home address, or "Office Space & Utilities" if it’s registered elsewhere. Then, enter the appropriate details under "Phone & Fax". *** More Information Again, you can claim for utility bills providing they are directly related to the running of your business. If you use your business assets for both work and personal use, work out the percentage that is just business use, and claim for that only.  If you work from home you might not want to claim for every single utility bill. In this instance, you can claim a flat rate on your tax return under Use of Home as Office: Home as Office Allowance (SimpleTax).    You can only use simplified expenses if you work for 25 hours or more a month from home. Hours of business use per month Flat rate per month 25 to 50 £10 51 to 100 £18 101 and more £26     other keywords: telephone, call, contact, ring, invoice, receipt, utility, bills, value, dues, tariff, charge, handset, desk, desktop
