How to Plan for Tax Before the Year Ends, Not After It
Tax planning works best before the year ends.
Once the financial year has closed, many options become limited. The accounts can still be prepared, tax can still be calculated and returns can still be filed, but some decisions are harder to change after the event.
The key point is this: tax planning is not only about reducing tax. It is about knowing your likely tax position early enough to make sensible business decisions.
A business that reviews profit, expenses, dividends, VAT, payroll and cash flow before year-end is less likely to be surprised by tax bills later. It also has more time to correct bookkeeping issues, gather missing records, review director withdrawals, plan investment and reserve cash.
For year-end accounts and Corporation Tax support, see Merranti’s Annual Accounts page.
Why tax planning before year-end matters
Many business owners only think about tax when the accounts are being prepared or when a payment deadline is close.
That is usually too late for proper planning.
Before year-end, you may still have time to:
- review profit
- check allowable expenses
- correct bookkeeping errors
- estimate Corporation Tax
- review dividends
- manage director’s loan accounts
- consider equipment purchases
- check VAT and payroll liabilities
- reserve cash for tax
- review pension contributions
- chase unpaid invoices
- plan Self Assessment liabilities
- avoid rushed year-end decisions
After year-end, the focus becomes more about reporting what has already happened.

Start with up-to-date bookkeeping
Tax planning depends on accurate records.
If bookkeeping is behind, you cannot reliably estimate profit, tax, VAT, payroll, director’s loan accounts or cash flow.
Before year-end, review whether the bookkeeping includes:
- sales invoices
- supplier bills
- receipts
- bank transactions
- credit card transactions
- payroll entries
- VAT returns
- CIS records, where relevant
- loan repayments
- asset purchases
- director withdrawals
- dividends
- personal costs paid by the business
If the records are incomplete, the first step is to clean them up. Tax planning based on poor bookkeeping can create false confidence.

Estimate your profit before the year closes
Profit is the starting point for most tax planning.
For limited companies, profit affects Corporation Tax, retained profit and dividend capacity. For sole traders, profit affects Self Assessment, Income Tax and National Insurance. For VAT-registered businesses, profit and cash-flow reviews also help show whether VAT is being handled properly.
Before year-end, review:
- income to date
- expected income before year-end
- direct costs
- overheads
- unpaid customer invoices
- unpaid supplier bills
- stock or work in progress
- finance costs
- payroll costs
- expected year-end profit
This does not need to be perfect, but it should be realistic enough to estimate tax and make decisions.

Review expenses before year-end
Pre-year-end is a good time to check whether business expenses have been recorded properly.
This does not mean spending money just to reduce tax. Spending £1 only to save a fraction in tax is not automatically sensible. The expense still needs to be commercially useful.
Review whether the business has recorded:
- accountancy fees
- software subscriptions
- insurance
- training
- office costs
- travel costs
- business mileage
- tools and equipment
- marketing
- professional fees
- home office costs
- phone and internet
- repairs and maintenance
- subcontractor costs
- materials
The key question is whether genuine business costs have been missed or coded incorrectly.

Consider equipment and asset purchases carefully
Some businesses consider buying equipment before year-end.
This might include:
- laptops
- tools
- machinery
- vans
- plant
- office furniture
- software
- workshop equipment
- safety equipment
Asset purchases can affect tax, but the timing and treatment depend on the type of asset, how it is used and the capital allowance rules.
The business should not buy equipment purely for tax reasons. The better question is whether the business genuinely needs the asset and whether cash flow can support the purchase.
Before buying, ask:
- Does the business need it?
- Will it improve profit, efficiency or capacity?
- Can the business afford it after tax, VAT and payroll?
- Is it a repair, expense or capital asset?
- Is finance involved?
- Will there be private use?
- What is the accounting and tax treatment?
For asset treatment in year-end accounts, see Merranti’s Annual Accounts page.

Review Corporation Tax early
Limited companies should estimate Corporation Tax before the accounts are finalised.
The Corporation Tax payment deadline is usually earlier than the Company Tax Return deadline. This can catch directors out if they wait until the filing deadline to think about tax.
Before year-end, directors should estimate:
- taxable profit
- Corporation Tax rate
- disallowable costs
- capital allowances
- losses brought forward
- expected Corporation Tax due
- cash reserved for payment
- effect of planned dividends
- retained profit after tax
This helps directors decide whether dividends are affordable and whether enough cash is being reserved.

Check dividends before declaring more
Dividends should not be based only on the bank balance.
A company may have cash in the bank but still owe VAT, PAYE, Corporation Tax, supplier bills or loan repayments. Dividends should usually be paid from available distributable profits after considering company tax and previous losses.
Before declaring dividends, directors should review:
- current profit
- retained profit
- previous losses
- Corporation Tax estimate
- dividends already paid
- available cash
- VAT and payroll liabilities
- supplier bills
- director’s loan account
- dividend paperwork
If the company does not have enough profit, dividends may create problems. Money already taken may need to be treated as a director’s loan account balance instead.

Review director’s loan accounts
A director’s loan account should be reviewed before year-end, not after.
This account records money moving between the director and company where the payment is not salary, dividends, expense reimbursement or repayment of money previously lent.
Problems often arise when directors:
- use the company card for personal spending
- take money out without payroll or dividend records
- pay personal bills from the company account
- take dividends without checking retained profit
- leave bookkeeping until year-end
An overdrawn director’s loan account can create tax issues and cash-flow pressure.
Before year-end, check:
- personal spending paid by the company
- director expenses paid personally
- dividends credited to the account
- repayments made
- whether the account is overdrawn
- whether action is needed before the year closes

Check VAT before the next return is due
If your business is VAT registered, year-end tax planning should include VAT.
VAT is not profit. VAT collected from customers may need to be paid to HMRC after input VAT is offset. If VAT is treated as spare cash, the business may run into pressure when the return is due.
Before year-end, review:
- VAT returns submitted
- VAT payments made
- VAT control account
- VAT on sales
- VAT on purchases
- VAT invoices
- reverse charge treatment
- VAT registration threshold, if not registered
- whether voluntary registration is worth considering
- whether VAT cash has been reserved
For VAT support, see Merranti’s VAT Services page.

Check payroll, PAYE and pension liabilities
Payroll can create liabilities that are easy to overlook.
If the business has employees or pays directors through payroll, pre-year-end planning should include a review of:
- gross pay
- PAYE
- employee National Insurance
- employer National Insurance
- pension contributions
- bonuses
- benefits
- payroll journals
- unpaid PAYE
- payroll year-end records
- directors’ salaries
Employers should also check whether payroll records agree with the accounts. If payroll figures are posted incorrectly, profit and liabilities may be wrong.
For payroll support, see Merranti’s Payroll page.
Sole traders should review Self Assessment early
Sole traders pay tax personally through Self Assessment.
A sole trader should estimate tax before the end of the tax year rather than waiting until January.
Before the tax year ends, review:
- turnover
- allowable expenses
- business mileage
- home office costs
- equipment purchases
- pension contributions
- payments on account
- student loan repayments
- property income
- other taxable income
- savings or dividend income
- expected tax due
Payments on account can surprise sole traders because they may need to pay towards the next tax year as well as settle the previous year.
For Self Assessment support, see Merranti’s Self Assessments page.
Construction businesses need extra pre-year-end checks
Construction businesses often need more detailed year-end planning because CIS, VAT, subcontractors, materials and retentions can affect both profit and cash flow.
Before year-end, construction businesses should review:
- CIS suffered
- CIS deducted from subcontractors
- subcontractor statements
- VAT domestic reverse charge
- retentions
- staged payments
- materials
- job costing
- plant and tool purchases
- payroll
- work in progress
- customer balances
- supplier balances
A construction business may look profitable overall but still have weak cash flow if retentions, materials and subcontractor payments are not tracked properly.

Build a tax reserve before the deadline
One of the simplest ways to reduce stress is to set tax cash aside before the payment deadline arrives.
This might include separate reserves for:
- Corporation Tax
- VAT
- PAYE
- Self Assessment
- CIS
- dividend tax
- payroll liabilities
A separate bank account or internal cash pot can help stop tax cash being confused with trading cash.
The right amount depends on the business. A VAT-registered company with payroll and subcontractors needs a different reserve strategy from a sole trader consultant.
The important point is to estimate regularly and reserve cash before the bill arrives.
Pre-year-end tax planning checklist
Before the year ends, review:
- Is bookkeeping fully up to date?
- Are all sales invoices raised?
- Are supplier bills recorded?
- Are expenses categorised correctly?
- Are any receipts or invoices missing?
- What is the estimated profit?
- What tax is likely to be due?
- Is Corporation Tax being reserved?
- Are VAT records reconciled?
- Is payroll posted correctly?
- Are PAYE and pension liabilities clear?
- Are dividends supported by profit?
- Is the director’s loan account under control?
- Are asset purchases planned properly?
- Are unpaid customer invoices being chased?
- Are supplier balances accurate?
- Are Self Assessment payments on account expected?
- Are CIS records complete?
- Is there enough cash for tax?
- What decisions need to be made before year-end?
This checklist should be reviewed before the accounting period closes, not after accounts are due.

FAQ
Why should I plan for tax before year-end?
Planning before year-end gives you time to review profit, expenses, dividends, VAT, payroll and cash reserves while decisions can still be made. After year-end, many options are more limited.
What should a limited company review before year-end?
A limited company should review profit, Corporation Tax, dividends, director’s loan accounts, VAT, payroll, supplier bills, customer invoices, asset purchases and retained profit.
Can tax planning reduce my tax bill?
Tax planning may help identify allowable expenses, timing issues or reliefs, but it should not be treated as a guaranteed tax reduction. It mainly helps you understand and manage your tax position earlier.
Should I buy equipment before year-end to reduce tax?
Only if the equipment is genuinely needed and affordable. Buying something just to reduce tax can weaken cash flow. The tax treatment also depends on the asset and current rules.
How early should I start tax planning?
Many businesses should review tax at least quarterly. A detailed pre-year-end review is useful a few months before the accounting period or tax year closes.
Can Merranti help with pre-year-end tax planning?
