Student Loans and Self-Employment
If you’re self-employed, your student loan repayments work differently from PAYE. Instead of automatic monthly deductions from your payslip, you repay through your annual Self Assessment tax return — and that changes how you need to plan your finances.
How Repayments Work Through Self Assessment
PAYE (Employed)
- •Monthly deductions from payslip
- •Automatic — employer handles it
- •Based on salary each pay period
Self Assessment (Self-employed)
- •Annual lump sums (Jan & Jul)
- •You calculate and submit
- •Based on net profit for the year
When you’re employed, your employer deducts student loan repayments from your salary each month via PAYE. When you’re self-employed, there is no employer to do this — HMRC calculates your repayment based on your Self Assessment tax return instead.
This means your repayments are annual, not monthly. You typically pay in two lump sums: one in January and one in July (as part of HMRC’s payment on account system). The repayment is 9% of your net profit above the repayment threshold for Plan 2 and Plan 5, or 6% for Postgraduate Loans.
Because payments are based on your profit — not your total revenue — business expenses you claim directly reduce your student loan repayment as well as your tax bill.
What Counts as Income?
HMRC looks at your total taxable income when calculating student loan repayments. For the self-employed, this includes:
Net Profit
Revenue minus allowable business expenses from self-employment.
Employment Income
Salary from a PAYE job if you also have one alongside freelancing.
Other Taxable Income
Rental income, dividends, interest above your personal savings allowance, etc.
All of these sources are combined to determine whether you exceed the repayment threshold and how much you owe.
Mixed Employment
Many freelancers also have a part-time or full-time PAYE job. If this applies to you, HMRC collects repayments through both mechanisms:
- Your employer deducts repayments from your salary automatically via PAYE
- Your Self Assessment tops up the difference based on your combined total income
For example, if your PAYE salary is below the threshold but your combined income (salary + freelance profit) is above it, you’ll owe the full repayment through Self Assessment. If your PAYE income alone exceeds the threshold, your employer already deducts repayments — and Self Assessment adds further repayments on your self-employment profit.
Common Mistakes to Avoid
Not budgeting for annual payments
Unlike monthly PAYE deductions, Self Assessment repayments arrive as large lump sums. A sudden bill of several thousand pounds in January can catch freelancers off guard.
Late filing penalties
Missing the 31 January Self Assessment deadline means a £100 penalty — plus your student loan repayment is delayed, which can lead to estimated charges from HMRC.
Underestimating income
If your payments on account are based on a lower previous year, you may face a balancing payment when your actual profit is higher than expected.
Not claiming legitimate expenses
Every pound of allowable business expense you miss increases your net profit — and therefore your student loan repayment. Common overlooked expenses include home office costs, professional subscriptions, and travel.
Practical Tips for Freelancers
Set aside 9% monthly
Calculate 9% of your profit above the repayment threshold each month and put it in a separate savings account. This avoids a nasty surprise when your tax bill arrives.
Register for Self Assessment early
You must register with HMRC by 5 October following the end of the tax year in which you became self-employed. Registering late can result in penalties.
Keep good records
Track all income and expenses throughout the year. Good record-keeping makes filing easier and ensures you claim every expense you’re entitled to.
Consider an accountant
An accountant familiar with student loans can help you optimise your expenses, avoid mistakes, and ensure your repayments are calculated correctly.
Key Takeaways
- Self-employed borrowers repay through Self Assessment, not PAYE — expect annual lump-sum payments, not monthly deductions.
- Repayments are based on net profit, so claiming all legitimate business expenses directly reduces what you owe.
- If you have mixed income (PAYE + freelance), HMRC collects through both mechanisms based on your combined total income.
- Budget monthly by setting aside 9% of profit above the threshold to avoid being caught out by large tax bills.
