But it can also be used by partners in a business partnership, if you have to pay Capital Gains Tax, if you have to pay the High Income Child Benefit Charge, or if you\u2019ve simply got any untaxed income, such as income from savings, investments or pensions.<\/p>\n\n\n\n<p>To use Self Assessment, you\u2019ll first need to register with HMRC. This gives you a Unique Taxpayer Reference, or UTR, that will be linked to your account. Each year you can then either send a paper tax return by 31 October following the end of the tax year, or submit an online tax return by 31 January. The majority of people use the online service.<\/p>\n\n\n\n<p>The tax return details your business income and expenses, by which your tax liability is derived. If you use the online Self Assessment tax return, HMRC will calculate this for you.<\/p>\n\n\n\n<p>Any outstanding tax liability must be paid by 31 January, as well as any payment on account for the current year, if HMRC has agreed this with you.<\/p>\n\n\n\n<p>If you\u2019re employed then Income Tax is collected automatically by your employer from your wages via the Pay as you Earn (PAYE) system, so there\u2019s usually no need to use Self Assessment unless you have additional income outside of this (e.g. you\u2019re a landlord, or you have a side hustle that generates more than the \u00a31,000 trading allowance).<\/p>\n\n\n\n<div class=\"single-cta gated-content\">\n\t<div class=\"single-cta__positioner\">\n\t\t<div class=\"single-cta__wrapper
