Then you&#8217;ll need to determine what share of your mileage is professional. This percentage determines:<\/p>\n<ul>\n<li class=\"font-inter\">\n<p class=\"no-margin font-inter\">how much VAT you can reclaim on your car expenses<\/p>\n<\/li>\n<li class=\"font-inter\">\n<p class=\"no-margin font-inter\">how much you can deduct on your personal income tax<\/p>\n<\/li>\n<\/ul>\n<p class=\"no-margin font-inter\">The higher your professional use, the more you can deduct. But the tax authorities will also expect you to be able to substantiate this percentage in case of an audit.<\/p>\n<p class=\"no-margin font-inter\">\n<hr>\n<p class=\"no-margin font-inter\">\n<h1 class=\"font-degular\" id=\"h_cf336a91d2\">\ud83d\udc49 How do you calculate your professional use percentage?<\/h1>\n<p class=\"no-margin font-inter\">The formula is simple: you divide your business mileage by your total mileage.<\/p>\n<div class=\"intercom-interblocks-callout\" style=\"background-color: #feedaf80; border-color: #fbc91633;\">\n<p class=\"intercom-align-center no-margin font-inter\"><b>(number of professional km per year \u00f7 total number of km per year) \u00d7 100<\/b><\/p>\n<\/div>\n<p class=\"no-margin font-inter\"><b>Example:<\/b> in 2025, you drive a total of 20,000 km, of which 13,000 km are for professional purposes.<\/p>\n<p class=\"no-margin font-inter\">\n<p class=\"no-margin font-inter\">\u2192 Your professional use: (13,000 \u00f7 20,000) \u00d7 100 = <b>65%.<\/b><\/p>\n<p class=\"no-margin font-inter\">\n<hr>\n<p class=\"no-margin font-inter\">\n<h1 class=\"font-degular\" id=\"h_6db096c118\">\ud83d\ude97 What about commuting to your usual workplace?<\/h1>\n<p class=\"no-margin font-inter\">\n<p class=\"no-margin font-inter\">There&#8217;s an important exception to keep in mind: your daily commute.<\/p>\n<ul>\n<li class=\"font-inter\">\n<p class=\"no-margin font-inter\">Your commute to a fixed workplace counts as private use, not professional use.
