Review your finances halfway through the tax year and identify opportunities to improve your tax position.
The tax year can move quickly, and waiting until the end of the year to think about tax planning can leave small businesses with fewer options and unnecessary financial pressure.
A mid year tax planning review gives you an opportunity to look at your income, expenses, profits and future plans while there is still time to take sensible action.
For self employed individuals and small businesses, good planning is not about avoiding tax. It is about using legitimate reliefs and allowances, keeping accurate records and making informed decisions within HMRC rules.
Why mid year tax planning matters
A mid year review can help you understand where your business currently stands and what your tax position could look like by the end of the year.
It can help you:
• Estimate your potential tax liability
• Identify allowable expenses you may have missed
• Plan for upcoming tax payments
• Review planned business purchases
• Improve cash flow
• Prepare for changes in your business
Taking action early generally gives you more time to make sensible decisions.
Review your income and profit
Start by reviewing your income from the beginning of the current tax year.
Compare your current figures with previous years and consider whether your business is growing, slowing down or following a seasonal pattern.
Your review should consider:
• Total business income
• Business expenses
• Current profit
• Expected income for the remainder of the year
• Any significant changes in trading activity
Understanding your expected profit is particularly important because your tax liability is generally based on taxable profit rather than simply the amount of money coming into your business.
Check your allowable expenses
Reviewing expenses is one of the simplest areas to improve your tax position.
HMRC allows self employed individuals to claim qualifying business costs, including areas such as office costs, business travel, insurance, marketing and certain professional costs. The expense must meet the relevant HMRC rules before it can be claimed.
Check that you have recorded expenses such as:
• Business insurance
• Software and subscriptions
• Office costs
• Business travel
• Advertising and marketing
• Professional services
• Business telephone and internet costs
• Qualifying equipment and other business purchases
Do not claim a cost simply because it was paid from a business account. Personal expenses should not be treated as business deductions.
Review planned equipment purchases
If your business needs new equipment, computers, machinery or other qualifying assets, a mid year review is a good time to consider the tax treatment before making the purchase.
Depending on your accounting method and the type of asset, different rules may apply, including capital allowances.
The important point is not to buy something you do not need simply because it may provide tax relief. A tax saving does not make an unnecessary purchase financially worthwhile.
Plan for your upcoming tax bill
A profitable business can still experience cash flow problems if tax payments have not been planned for.
Review how much you may need to set aside for:
• Income Tax
• National Insurance where applicable
• Payments on account
• VAT where applicable
• Corporation Tax for limited companies
Creating a tax reserve throughout the year can make future payment deadlines much less stressful.
Review pension planning
Pension contributions can form part of wider tax and retirement planning.
For eligible individuals, pension contributions may provide tax relief while also helping build long term financial security.
The rules can be affected by your income, pension arrangements and personal circumstances, so larger contributions should be reviewed carefully before making a decision.
Consider your business structure
If your business has grown significantly, it may be worth reviewing whether your current structure remains suitable.
For example, a business operating as a sole trader may eventually consider whether becoming a limited company is appropriate.
This decision should not be based on Corporation Tax alone. You should also consider administration, National Insurance, how you take money from the business, legal responsibilities and your longer term plans.
Professional advice can help you compare the options before making a structural change.
Keep your bookkeeping up to date
Good bookkeeping is essential for effective business tax planning UK.
Review your records regularly and make sure:
• Income has been recorded correctly
• Expenses have supporting evidence
• Business and personal spending are separated
• Bank transactions have been reconciled
• Outstanding invoices are monitored
Accurate records give you a much clearer picture of your current tax position.
Prepare for Making Tax Digital
Making Tax Digital is now an important consideration for many self employed individuals and landlords.
From 6 April 2026, the rules apply to qualifying individuals with more than £50,000 of qualifying income from self employment and property. The threshold is due to reduce to more than £30,000 from April 2027 and more than £20,000 from April 2028.
Those within the rules must keep digital records and send quarterly updates using compatible software. For the 2026 to 2027 tax year, the standard quarterly update deadlines are 7 August, 7 November, 7 February and 7 May.
Preparing your bookkeeping early can make these requirements much easier to manage.
Review your tax planning before the year ends
A mid year review should not be treated as a one off exercise.
As the year progresses, revisit:
• Your expected income
• Your business expenses
• Your cash flow
• Planned purchases
• Pension contributions
• Your expected tax liability
This gives you an opportunity to adjust your plans as your business circumstances change.
Common tax planning mistakes to avoid
Small businesses can lose valuable opportunities by:
• Leaving tax planning until the end of the year
• Forgetting legitimate allowable expenses
• Making unnecessary purchases purely for tax relief
• Failing to budget for tax payments
• Mixing personal and business spending

• Making major financial decisions without checking the tax consequences
Good planning should support your business rather than complicate it.
