It&#8217;s the UK&#8217;s tax, payments and customs authority. In short, it collects the money that pays for public services. It also gives targeted financial support to families and individuals, and it values property to help work out tax and benefits.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Which taxes does HMRC collect?<\/h3>\n\n\n\n<p>HMRC collects several taxes, including:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><a href=\"https:\/\/taxfix.com\/en-uk\/glossary\/income-tax\/\">Income Tax<\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/taxfix.com\/en-uk\/glossary\/capital-gains-tax-cgt\/\">Capital Gains Tax<\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/taxfix.com\/en-uk\/glossary\/inheritance-tax-iht\/\">Inheritance Tax<\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/taxfix.com\/en-uk\/glossary\/company-tax\/\">Corporation Tax<\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/taxfix.com\/en-uk\/glossary\/vat\/\">VAT<\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/taxfix.com\/en-uk\/calculator\/national-insurance\/\">National Insurance<\/a><\/li>\n<\/ul>\n\n\n\n<p><strong>Income Tax<\/strong> and <strong>Capital Gains Tax<\/strong> are the ones most relevant to <a href=\"https:\/\/taxfix.com\/en-uk\/glossary\/self-assessment\/\">Self Assessment tax returns<\/a>.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Does your tax return end up with them?<\/h3>\n\n\n\n<p>Yes. HMRC collects tax, so it also receives the tax returns that go with it. No matter who prepares your tax return, it ends up with HMRC.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What is Taxfix?<\/h2>\n\n\n\n<p><a href=\"https:\/\/taxfix.com\/en-uk\/self-assessment-tax-returns\/\"><strong>Taxfix<\/strong><\/a> is a paid tax platform, separate from HMRC. It connects people with <a href=\"https:\/\/taxfix.com\/en-uk\/platform\/changing-tax-accountants-5-reasons-to-switch-to-taxscouts\/\">UK tax accountants<\/a> and <a href=\"https:\/\/taxfix.com\/en-uk\/bookkeeping\/\">digital tools<\/a>, so their returns can be prepared and filed with HMRC.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">How Taxfix works<\/h3>\n\n\n\n<p>Taxfix UK offers services for <a href=\"https:\/\/taxfix.com\/en-uk\/self-assessment-tax-returns\/\">tax returns<\/a>, <a href=\"https:\/\/taxfix.com\/en-uk\/tax-advice\/\">tax advice<\/a>, <a href=\"https:\/\/taxfix.com\/en-uk\/limited-company-tax-returns\/\">company tax returns<\/a>, bookkeeping and <a href=\"https:\/\/taxfix.com\/en-uk\/making-tax-digital\/\">Making Tax Digital for Income Tax (MTD)<\/a>. You can access them through the Taxfix app and platform.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">What else does Taxfix offer?<\/h3>\n\n\n\n<p>Taxfix also offers <a href=\"https:\/\/taxfix.com\/en-uk\/tax-consultation-advice\/\"><strong>tax advice<\/strong><\/a><strong> <\/strong>from an accountant, to help you understand your tax position. You can choose the tax return service, the tax advice service, or both together in one bundle.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">What Taxfix does not do<\/h3>\n\n\n\n<p>Taxfix does not replace HMRC or your obligation to register for Self Assessment. It also does not work out your tax bill. HMRC does that. Taxfix does not file your return until you have confirmed the information you provided.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Is Taxfix an alternative to HMRC?<\/h2>\n\n\n\n<p>There is no alternative to HMRC as the tax authority, because every UK Self Assessment return is submitted to HMRC. You can file yourself through HMRC&#8217;s free online service, or use a paid service such as Taxfix that prepares and submits the return for you.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><td><strong>Option<\/strong><\/td><td><strong>What it is<\/strong><\/td><td><strong>Cost<\/strong><\/td><td><strong>What you do<\/strong><\/td><\/tr><tr><td>HMRC online<\/td><td>Online service for filing your return<\/td><td>Free<\/td><td>You prepare and submit the return yourself<\/td><\/tr><tr><td>Taxfix<\/td><td>Return prepared by an accountant<\/td><td>Fixed fee<\/td><td>You upload your documents and approve the return before it is filed<\/td><\/tr><tr><td>Traditional accountant<\/td><td>An ongoing relationship with one accountant<\/td><td>Varies, so check fees before you agree<\/td><td>Depends on your agreement with the accountant<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">Who needs to file a Self Assessment?<\/h2>\n\n\n\n<p>If you&#8217;re an employee with only a salary, you usually don&#8217;t need to file.
