Frequently Asked Questions
What income should I include in my Self Assessment if I have multiple jobs?
When managing multiple sources of income, it’s essential to keep accurate records. Here are some key points to remember:
Report all income: It’s important to declare all sources of income, including wages, rental income, freelance earnings, oversea income and any other taxable income you receive.
P60s & P45s: Safeguard your P60s (annual income statements) and P45s (leaving certificates) as they contain crucial information for your tax return.
Self-employed income: If you’re self-employed, you’ll need to calculate your profits and losses for the tax year.
By staying organised and mindful of these details, you can ensure that no income goes unaccounted for.
Do I need to file a Self Assessment if I’m a director of a company with no salary?
Even if you’re not receiving a salary, serving as a company director can still have tax implications. Here are the key points to keep in mind:
Benefits-in-kind (BiKs): Any benefits you receive from your company, such as a company car or accommodation, may be subject to taxation.
Director’s loan account: Any loans you receive from your company could have tax implications.
Company dividends: If your company distributes dividends, these are typically taxable.
We will guide you in understanding your circumstances and determining whether you need to complete a Self Assessment.
Can you help me claim expenses on my Self Assessment return?
laiming legitimate expenses can effectively lower your tax bill when filing your taxes. It’s essential to identify and claim the following:
Business expenses: If you are a self-employed individual, you can claim the costs directly related to your business, including travel, office supplies, and equipment.
Employee expenses: If you are an employee, you may be eligible to claim specific expenses, such as work-related travel costs or safety clothing.
Our tax experts will assist you in uncovering all the potential tax benefits hidden within your expenses.
What if I make a mistake on my submitted Self Assessment?
