Self assessment as a Go Mammoth netball umpire, referee, or fitness instructor

If you’re earning money from umpiring netball, refereeing sports, or instructing fitness classes through GoMammoth, you’ll need to submit a self assessment tax return to HMRC. Accurately reporting your income and expenses is crucial to ensure compliance with UK tax laws. This guide will walk you through the process, making it simple and manageable.

Step 1: Register for self assessment

The first step in your self assessment journey is to register with HMRC. Here’s how you can do it:

1. Visit the HMRC website and go to the self assessment registration section.

2. Complete the registration form: You’ll need your National Insurance number and personal details about your income.

3. Receive your Unique Taxpayer Reference (UTR) number: HMRC will send you a UTR by post. Keep this number safe as it’s essential for all your tax dealings.

Registering early is advisable to avoid any last-minute issues.

Step 2: Track your income and expenses

Keeping accurate records of your income and expenses is vital for a successful self assessment. Here’s what you need to do:

• Track your income: Record all payments received for umpiring, refereeing, or instructing. This includes fees from GoMammoth and any other related income.

• Maintain detailed records: Store all transaction records, including payment receipts, bank statements, and other relevant documents. This will help you accurately report your income and claim expenses.

Step 3: Understanding allowable expenses

You can reduce your taxable income by deducting allowable business expenses. Here are common expenses for netball umpires, sports referees, and fitness instructors:

• Sports equipment: Costs for any equipment used in your activities.

• Travel expenses: Mileage or public transport costs for traveling to and from your sessions.

• Uniform costs: Expenses for uniforms or clothing specific to your role.

• Insurance: Any insurance policies required for your work.

• Training materials: Costs for any courses or materials needed to maintain or improve your skills.

Keep all receipts and records of these expenses to ensure you can claim them accurately.

Step 4: Completing the self assessment form

Filling out your self assessment form involves several steps. Here’s a guide to help you through:

1. Log in to your HMRC account using your UTR and password.

2. Verify your personal details: Confirm and update your information if necessary.

3. Declare your income: Enter the total amount earned from umpiring, refereeing, and instructing.

4. Claim your expenses: List your allowable expenses to reduce your taxable income.

5. Calculate your tax owed: HMRC’s system will help you calculate the amount of tax you owe based on the information provided.

Ensure all information is entered correctly and double-check your entries.

Step 5: Review and submit

Before submitting your self assessment, it’s important to review all the information carefully:

• Check all entries: Make sure your income and expenses are accurately reported.

• Correct any errors: Fix any mistakes or typos.

• Submit your form: Once everything is correct, submit your self assessment online.

• Save a copy: Download and keep a copy of your completed return and the submission confirmation for your records.

• Start early: Give yourself plenty of time to gather documents and complete your return.
