The official guidance from the UK Student Loans Company (SLC) is straightforward. What gets confusing is the advice you may have read online, crewmate chat and calculating what you actually owe each month.

If you’re looking for the short answer – Yes, you do need to pay back your student loan, even if you work overseas on a Superyacht, Cruise Ship or any other vessel and qualify for Seafarers Earnings Deduction (SED).

Whether you work at home or overseas, are employed or self employed, your student loan payback is calculated on your gross income. Gross income is the total amount you earn (including base salary, tips, and bonuses) before any deductions are taken.

Bearing ‘gross income‘ in mind, this means that qualifying for Seafarers Earning Deductions holds no relevance to your student loan repayments.

If you qualify for SED (we can help you figure that out), the tax liability on your income will be £0, which is a great perk of working at sea. However, it does not mean your gross income goes to £0, that gross income that is stated on your payslip will be the same no matter what deductions have taken place.

Before we go any further. The information in our article reflects direct policy clarification provided by the Student Loans Company (SLC) via customer support calls in September 2026. If you work overseas, it is your obligation (not your employer, tax advisor, or anyone else) to contact the SLC for any further clarification and to pay back your loan.

How your repayments are collected

If you are employed by a UK company and are on their payroll (PAYE), student loans repayments are taken automatically from your salary. This article is to guide you through the steps if you are working overseas.

If you work overseas on a foreign-flagged vessel or Superyacht paid gross without UK payroll deductions, nothing is taken at source. You must self-report your gross pay directly to the SLC and make direct repayments.

Step-by-Step: Reporting to the SLC

If you are still seeking work on a ship and are not employed yet, you do not need to report to the SLC. It’s only once you have signed your contract and your employment status confirmed you need to do something about it.

Step 1: Declare employment once your job starts

Log into your Student Finance portal (or call 0300 100 0611) to declare that you are now working overseas. Check your contact details and correspondence address and update if needed.

Step 2: Gather your income evidence

Prepare standard proof of your gross earnings (gross means before any deductions were taken from your payslip). SLC will ask for:

  • A contract of employment (or Seafarers Employment Agreement) dated within the last 6 months.
  • Or 3 consecutive recent payslips showing total gross pay.

Step 3: Complete the Overseas Income Assessment

Fill out the online assessment form in your portal, upload your evidence, and enter the registered country address of your employer (the management company or vessel owner listed on your contract).

Step 4: Wait for your assessment

Processing normally takes 2–3 weeks. The SLC will calculate your repayment threshold based on your employer’s registered location and email you when your schedule is ready in your portal inbox.

Step 5: Set up your repayment method

If your gross salary exceeds the overseas threshold, you will pay 9%:

  • Direct Debit: Set up automatically using an active UK bank account.
  • Standing Order: Arranged manually with your bank using your SLC Customer Reference Number as the payment reference.

If you don’t give SLC all the information they need, they will charge a fixed monthly repayment, up to £618.80 per month, which is likely considerably higher than the amount you should be paying back. Fixed monthly repayment amounts can be found on the earnings thresholds table.

How much will I need to repay every month?

To understand what you will owe, it helps to know how UK student loans differ from regular debt.

How does a student loan work?

If we take a car loan or a mortgage, both loans are repaid in full with repayments starting the moment you receive the loan. A student loan is contingent on you earning a certain salary, called the “threshold” above which you start to repay the loan.

A student loan is provided via a Student Loan Company (SLC) a non-for profit organisation run by the Department for Education and funded by the UK tax payer.

There are many different types of student loans. Rules and regulations are applied differently depending on when you took the loan out, how much you earn and whether you are English, Scottish, Welsh or from Northern Ireland.

As of September 2026, there are four types of student loan:

  • Plan 1 taken out before 2012, payment threshold £26,900
  • Plan 2 taken between 2012 and 2023, payment threshold £29,385
  • Plan 4 Scottish undergraduate, payment threshold £33,795
  • Plan 5, taken after 2023, threshold £25,000

What are my monthly repayments

Calculating your repayment is simpler than it looks and is often smaller than people expect.

You do not pay 9% on your total earnings; you only pay 9% on what you earn above your plan’s threshold. If your monthly gross income is below the threshold, you pay £0.

The calculation is:

(Gross Monthly Pay − Monthly Threshold) × 9% = Monthly Repayment

Monthly Out-of-Pocket Cost (Plan 2 Benchmark)

Because the majority of active Superyacht crew currently repaying loans fall under Plan 2 (UK threshold of £29,385/year or ~£2,448/month), here is what actually comes out of your bank account each month based on total gross earnings (including base salary, charter tips, and bonuses):

  • £30,000 gross/year (~£2,500/month): ~£4.60 per month
  • £35,000 gross/year (~£2,916/month): ~£42 per month
  • £40,000 gross/year (~£3,333/month): ~£79.50 per month
  • £50,000 gross/year (~£4,166/month): ~£154.50 per month

The overseas employer adjustment

If you are working on Superyachts, it is likely your Superyacht management company is registered abroad so the SLC doesn’t use the standard UK threshold. Instead, they apply a country-specific cost-of-living threshold amount based on the registered country address of your employer (found on page 1 of your employment contract).

It basically means in countries with higher cost-of-living countries, the threshold goes up, meaning you pay less per month. In lower cost-of-living countries, the threshold drops, meaning you pay more per month.

Here is how Plan 2 thresholds changes across 5 example employer locations:

Country / TerritoryMonthly Threshold (Plan 2)Annual Threshold (Plan 2)
Cayman Islands£3,321£39,860
Isle of Man / Channel Islands£2,372£28,470
Marshall Islands£2,372£28,470
British Virgin Islands (BVI)£2,372£28,470
Malta£1,898£22,780

What about interest on the loan?

Interest accrues on your student loan continuously from the day it is issued until the balance is cleared in full or written off. If you do not make repayments, that interest keeps compounding in the background. As a result, your overall balance grows, and the total amount you owe becomes larger over time.

When you make regular repayments and reduce the main balance of your loan, the relative amount of interest added each month decreases alongside it. A smaller remaining balance naturally generates less interest over time.

What are my obligations to the SLC?

When taking out a student loan, you sign a contract with the SLC. This contract sets out the terms of the loan, prepayments and obligations on both sides. You have an obligation to keep the SLC informed of any changes, examples include:

  • Any changes to your circumstances.
  • If you move house
  • Leave your course or absent for more than 60 days
  • Plan to leave the country

Why does my SLC keep contacting me?

If you have left university and have not landed a job they will want to know what you are up to.

If you’re working overseas, the SLC might not automatically know your income status. Ignoring their requests can lead to higher, default repayment settings. It’s much easier to stay in touch and let them know your situation.

If you have taken a year out to travel or are not in full time employment or education, that’s fine, just let the SLC know what you are up to, they will update the system and leave you alone.

What happens if I do nothing…

If you work at sea you may think, “they can’t find me” or “I work offshore” I don’t pay tax” and just ignore your student loan. Sadly the SLC sees it differently, they will not give up.

If the SLC stops seeing income via PAYE or Self-assessment and flags you as overseas

  • If you have just left University, have not started UK employment but have opted for a career on a Superyacht/Cruise ship then at some point your SLC will contact you.
  • They will send you an Overseas Income assessment form. Reminders will be sent
  • You ignore the reminders
  • If the SLC can’t get hold of you then they will note you are non-compliant overseas borrower and may set higher monthly repayments, which can be as much as £618.80 per month
  • The SCL can put you onto the highest interest rate possible within the contract
  • Your debt accumulates
  • When you finally come back to the UK to start a new career you will have a big mess on your hands!

Getting help

Your Student Finance account is the best place to check your plan, balance and monthly repayment. If your situation has changed, or you’re about to head off on a new contract, it’s worth calling the SLC before you go rather than after.
