UK Tax Return Sample

Personal Details

Have you ever filed a tax return in the past before?

If so, it may be useful to have these available depending on the period of filing.

You will need your national insurance number and your UTR number (tax ID).

If you do not have a UTR number then an accountant can apply for one for you.

How long have you been working as a seafarer?

HMRC have a 4 year audit period.

This should be considered when deciding how many years returns to complete to achieve a position of tax transparency in the eyes of HMRC.

How many days have you spent in the UK?

Whilst there are other rules to consider, the most important one to comply with in order to qualify for the SED is the limit of 183 days spent onshore in the UK in any rolling 365 days.

Although it is not necessary to provide at the time of submitting a tax return, it would be prudent to keep records to prove where you were during any 12 month period.

This can be supported by records of air tickets, travel vouchers, hotel bills, visas and passports, and your seafarers discharge book.

Try using our free online seafarers tax days calculator.

It's quick and easy to use and will give you an instant answer as to whether you qualify under the seafarers earnings deduction.

What currency were you paid in and how much?

Although it is useful to have payslips, they are not mandatory when filing a tax return.

The objective is to report your income accurately and should include salary, tips and bonuses, plus the name of your employer and the vessel you worked on.

Have you received any income from land based employment?

Payslips, P60 or P45 will determine the tax paid on this and should be included as part of your return as a seafarer.

Do you receive any income from savings, investments or pensions?

It is important to include all income in relation to these as they may be subject to UK tax.

Have you ever used any cryptocurrency?

Cryptocurrency is an investment like any other and will be treated as such when assessing any gains, and therefore must be declared within your tax return.

Do you have any properties you rent out?

You will need to include any rental income from properties you own anywhere in the world.

For UK rental income, provided you have not exceed your personal allowance you will not be liable for tax on this.

Certain expenses can be offset so it is important to keep evidence of costs in relation to the property.

This includes loan interest, insurance payments, rates and ground rent, repairs and maintenance, legal and management costs along with other allowable expenses.
