Selling online? Whether it’s a hobby or a business, you may need to pay tax if your earnings exceed £1,000. From services to content creation, it’s vital to understand self-assessment rules and new reporting obligations for online platforms starting in 2024.

If you are selling anything through an online marketplace, it is important to know that you might be liable to pay tax, whether it is your main source of income or just something a part-time hobby. This applies to a range of activities, so it is worth understanding when you need to register for self-assessment and pay tax.

You may need to report your earnings and pay tax if you are doing any of the following:

• Buying goods to resell, or making things to sell (even if it’s just a hobby that you sell items from);
• Offering services online, such as dog walking, gardening, repairs, tutoring, food delivery, babysitting, or hiring out equipment;
• Creating online content, whether that's videos, podcasts, or even social media influencing; or
• Earning income by renting out property or land, like letting a holiday home, running a bed and breakfast, or renting out a parking space on your driveway.

There is a Trading Allowance you can claim that allows you to earn up to £1,000 a year from self-employment without having to pay tax or register as self-employed. But if you go over that £1,000 threshold, you will need to register with HMRC as self-employed and submit a self-assessment tax return.

If you are just selling personal items, such as second-hand clothes or unwanted electrical goods, you typically do not need to worry about registering for tax. This is not considered a business activity, so it does not count as trading in the eyes of HMRC.

For those using online platforms to sell goods or services, there are new reporting obligations. Any relevant information about your sales may be reported to HMRC by the platform you use. There is a new requirement for online platforms to report pertinent information collected about online sellers between 1 January 2024 to 31 December 2024 to HMRC by 31 January 2025. This will only happen if you have sold 30 or more items or earned £1,700 (or €2,000) in the calendar year. The platform will also provide you with a copy of the information they send to HMRC, which can be helpful when you need to submit your own tax return.

A significant amount of online information about companies is available to the public on the Companies House website. The information available through Companies House can be an important resource for anyone looking to research a company. What makes this particularly valuable is that a significant portion of the data is freely available to the public.

The range of publicly available information can be used for various purposes, including due diligence, background checks, and monitoring the financial health of companies.

Among the key details that can be accessed through Companies House are:

• Company Information: This includes basic but essential details such as the company’s registered address, its date of incorporation, and its status.
• Company Officers: You can access a list of current and resigned officers of the company, which includes directors, company secretaries, and other key individuals.
• Document Images: Companies House maintains a digital archive of official documents filed by companies, such as annual accounts, articles of association, and resolutions.
• Mortgage Charge Data: For companies that have taken out loans or entered into security agreements, information about mortgage charges is available.
• Previous Company Names: If a company has changed its name in the past, this information is also made available.
• Insolvency Information: Companies House also holds records of any insolvency proceedings.

In addition to this, Companies House offers a convenient service where individuals and businesses can set up free email alerts. These alerts notify you whenever there are updates to a company’s details, such as a change in director or registered address.

Beneficial loans, where employees benefit from cheap or interest-free loans from their employer, can trigger tax implications. However, certain exemptions, like loans under £10,000 or qualifying loans, eliminate the need for employers to report or pay tax on them.

An employee can receive a benefit when they are provided with a loan from their employer that is either cheap or interest-free. The benefit arises from the difference between the interest the employee pays, if any, and the market rate they would have to pay if they obtained a loan from another source. These types of loans are commonly referred to as beneficial loans.

However, there are several situations in which beneficial loans may be exempt, meaning employers don’t have to report anything to HMRC or pay tax and National Insurance. One of the most common exemptions applies to small loans where the total outstanding balance to the employee is less than £10,000 throughout the entire tax year.

Other exemptions include:

• Loans given in the normal course of a domestic or family relationship, where the loan is made by an individual (not a company they control, even if they are the sole owner and employee).
• Loans provided to an employee for a fixed, invariable period, with a fixed, invariable interest rate that is equal to or greater than HMRC’s official interest rate when the loan was taken out.
• Loans offered on the same terms and conditions to the general public, typically seen with commercial lenders.
• Loans that are ‘qualifying loans’ for tax relief, meaning all the interest is eligible for tax relief.
• Loans made through a director’s loan account, as long as the account is not overdrawn at any point during the tax year.

In these cases, no tax or reporting requirements would apply to the employer.

Employers can voluntarily register to report and account for tax on certain benefits and expenses via the RTI system before the start of the tax year. This process, known as payrolling, eliminates the need to submit P11D forms for the selected benefits at the end of the tax year.

The deadline for submitting P11D, P11D(b), and P9D forms for the 2024-25 tax year is 6 July 2025. These forms can be submitted via commercial software or HMRC’s PAYE online service, as HMRC no longer accepts paper submissions. Employees must also receive a copy of the information by the same date.

Employees must also be provided with a copy of the information relating to them on these forms by the same date. P11D forms are used to provide information to HMRC on all Benefits in Kind (BiKs), including those under the Optional Remuneration Arrangements (OpRAs) unless the employer has registered to payroll benefits.

A P11D(b) is still required for Class 1A National Insurance payments regardless of whether the benefits are being reported via P11D or payrolled. The deadline for paying Class 1A NICs is 22 July 2025 (or 19 July if paying by cheque).

If no benefits are provided during the tax year, employers can either submit a 'nil' return or notify HMRC that no return is required. Penalties apply for late submissions or payments, of £100 per 50 employees for each month a P11D(b) is late.

Inheritance Tax (IHT) impacts estates over £325,000, with rates of 40% on death and 20% on certain gifts. A 36% reduced rate applies if 10% of the estate is left to charity. Executors must value estates and may need to file tax returns for the deceased and their estate.

The current IHT nil rate band is £325,000 per person, below which no IHT is payable. This is the amount that can be passed on free of IHT as a tax-free threshold.

A reduced rate of IHT of 36% (reduced from 40%) applies where 10% or more of a deceased’s net estate after deducting IHT exemptions, reliefs and the nil rate band is left to charity.

In order to ascertain whether or not IHT is due, the personal representative (an executor or administrator) of the deceased must value the deceased's estate. The personal representative is legally responsible for dealing with the deceased’s money, property and possessions (their estate). As part of this process, a tax return for the deceased may be required.

 This could be:

• a self-assessment tax return for income the person earned before they died; or
• a separate self-assessment tax return for income the ‘estate’ generated after the person died.
