Beware of mixed private and professional costs!
Telephone and internet costs 📱 are considered as "mixed" costs by the tax authorities (a telephone subscription is generally also used for private purposes).
For tax and VAT purposes, a distinction must be made between the following two cases :
Individuals: you apply a professional quota limiting the deduction. Example: if you are self-employed as your main occupation, a professional use rate of 75% is consistent (50% in the case of additional self-employment). On this professional share, you recover 100% of the VAT.
Company: a benefit in kind is applied to the manager. This is a form of fictitious remuneration, the consequence of which is an increase in personal income tax. A fixed amount is set by the ONSS (see ONSS website). For VAT, a tolerance allows you to apply a general flat rate of 75% recovery, unless you prove a different % of professional use.
💡 When you have a telephone subscription shared between private and professional use, deductibility is necessarily limited. Thanks to the BILLY application, which requires a telecom subscription and is essential for keeping track of your accounting, you can justify a higher deductibility.
