Going Solo? Get Registered For Self Assessment Quickly

Starting your own business is exciting! But before you dive in, there’s one key step: registering as self-employed with HMRC. This ensures you pay the right taxes.

The good news? It’s:

  • Simple: The registration process is straightforward and hassle-free.
  • One-time: You only need to register once, not every year.
  • All-inclusive: This registration covers both Income Tax and National Insurance contributions (NICs).

So, get registered and get going with your self-employed journey!

Registering is Easy!

Step 1: Create your HMRC online account

This is your one-stop shop for managing your self-employed taxes. Signing up is quick, and you’ll receive a user ID.

Step 2: Register for Self Assessment

Log back into your account and choose “Add a Tax” followed by “Self Assessment.” Select “Sole Trader” if you’re running the business by yourself.

Step 3: Provide your details

Enter your start date as a self-employed individual, National Insurance number (you can find instructions for obtaining one if needed), and a brief description of your work (e.g., freelance writer, web developer).

Step 4: Submit and Activate

Review everything and click submit. You’ll receive a letter with your Unique Taxpayer Reference (UTR).

Activate your UTR using the separate activation code that arrives within 10 days.

Alternatively:

Prefer paper forms? Download the SA1 form from HMRC’s website, fill it out, and mail it in. Keep in mind this method takes longer to process.

Important Note:

Register by October 5th to avoid any penalties.

Bonus Tip:

Save your UTR and activation code for future reference!

Already Registered? Filing Your Return is Simple

Great news! Filing your self-employed tax return is similar to registering.

Here’s what you need to do:

  • Use the online CWF1 form instead of registering again.
  • Simply log in with your existing HMRC credentials (username and 10-digit UTR number) you used when you first registered.

Heads Up, Construction Workers: Register for CIS

If you’re a builder, painter, carpenter, or another self-employed worker in construction, HMRC has a special scheme for you: the Construction Industry Scheme (CIS).

Here’s the deal: registering for CIS ensures you pay the right tax rate (typically 20%). If you don’t register, you might end up paying a higher rate (30%).

Want to avoid the extra tax?

Get registered for CIS with HMRC. It’s easy and helps ensure you keep more of your hard-earned cash.

Congratulations! Now for the Extras

You’ve conquered registering for Self Assessment. Here are some key things to remember:

  • Be record-keeping savvy: Save your invoices and receipts for tax purposes.
  • File your Self Assessment tax return annually: This is how you declare your income and pay your Income Tax. The deadline is January 31st each year.
  • Pay National Insurance: You’ll likely need to pay Class 2 and/or Class 4 National Insurance contributions.
  • Register for VAT (optional): If your turnover hits £85,000 or more, you’ll need to register for VAT.
  • Heads up about Payment on Account: You’re automatically enrolled in this system to spread out your tax bill throughout the year with advance payments.
