Yes—HMRC can collect your Self Assessment bill through your PAYE tax code, but only if you meet **all** the eligibility rules. In practice, this means the tax is collected from your salary or pension via PAYE deductions rather than you making a separate payment. ## HMRC’s conditions (what must be true) You can pay through your PAYE tax code if **all** of the following apply: - **You owe less than £3,000** on your Self Assessment bill. - **You already pay tax through PAYE** (for example you’re employed or you receive a company pension). - **You submit your return by the right deadline** (see below). > Important: You **cannot** make a part payment to bring what you owe below £3,000 in order to qualify. ## The submission deadlines (to use your tax code) To have your Self Assessment collected through your PAYE tax code, you must submit: Return type Deadline to submit (to pay via tax code) Paper return 31 October Online return 30 December ## How it’s set up (do you need to request it?) If you meet the conditions, HMRC will **automatically** collect what you owe through your tax code—**unless you asked them not to** on your tax return. ## When you cannot pay this way (common reasons) Even if you’re within the £3,000 limit and have PAYE income, you may not be able to use your tax code if: - you do not have enough PAYE income for HMRC to collect it - you would pay more than 50% of your PAYE income in tax - you would end up paying more than twice as much tax as you normally do - you owed £3,000 or more but made a part payment to reduce the amount you owe to less than £3,000 Also, if you’re self-employed, you cannot pay **Class 2 National Insurance** through your tax code unless it’s been due since before 6 April 2015. ## What it looks like in your payslip If HMRC collects the bill through your tax code, the amount is usually taken in **equal instalments over 12 months**, alongside your normal PAYE deductions. ## Quick checklist - My Self Assessment bill is **under £3,000** - I already pay tax through **PAYE** - I submitted my return by **31 October (paper)** or **30 December (online)** - I did not opt out of paying through my tax code on my return ## Summary You can pay your Self Assessment bill through your PAYE tax code if you owe **less than £3,000**, already pay tax through **PAYE**, and submit your return by **31 October (paper)** or **30 December (online)**. If you qualify, HMRC will normally collect it automatically through your tax code unless you opted out.
