Student loans & Self Assessment
If you’re in Self Assessment and the Student Loans Company (SLC) says you were in repayment for the year, HMRC will add a student loan charge to your return: 9% of income above your Plan 1/2/4 threshold and 6% above the Postgraduate Loan threshold. It’s based on your total SA income (employment, self-employed, property, etc.), minus anything already taken via […]
Side income & Self Assessment
What counts as “side income”? Anything you earn outside your main PAYE job: online selling, crafting, freelancing, rides/deliveries, tutoring, photography, pet care, short-term lets, hiring out kit, content/influencer income, matched-betting affiliate fees, etc. Income from letting property, interest/dividends, or one-off sales of valuable items can also sit alongside, but they’re taxed under different rules than trading.
Pension income
Most pension income is dealt with through PAYE, so you only use Self Assessment when something isn’t fully taxed, for example, State Pension, drawdown/annuity shortfalls, or any untaxed payments. If you’re a higher- or additional-rate payer, claim extra relief on relief-at-source personal contributions (such as a SIPP); net pay and salary sacrifice already give full relief in payroll. Enter contributions in the SA100 […]
