Being well prepared for your accountant can save time, reduce stress and help ensure that your accounts and tax returns are accurate and completed on time. The more organised your information, the more your accountant can focus on giving you value-added advice rather than chasing missing data.
Good preparation supports:
Accurate financial records
Timely statutory and tax filings
Better strategic financial advice
Reduced professional fees
Lesser risk of errors and penalties
Whether it’s your first year with an accountant or your tenth, a systematic approach to preparing records is key to a successful working relationship.
Below is a guide to the essential documents and information your accountant will typically need. Providing these early in the process helps streamline work and reduces follow-ups.
Compile statements for all business accounts covering the entire accounting period.
This allows your accountant to:
Reconcile balances
Identify unidentified transactions
Verify income and expenses
Ensure that personal and business accounts are separate wherever possible.
Provide:
Sales invoices
Point-of-sale summaries
Online sales reports
Organised sales information ensures revenue is correctly captured and classified.
Gather all purchase invoices, receipts and bills, including:
Supplies and materials
Utilities and rent
Subcontractor costs
Professional fees
Well-organised expense records reduce the risk of missing legitimate deductions.
If you have employees or pay yourself a salary:
Provide PAYE records
Pension contributions
National Insurance details
Employee benefits or expenses
Accurate payroll records ensure correct reporting to HMRC and avoid issues with PAYE, NICs and pensions.
If your business is VAT-registered:
Provide VAT sales and purchase records
Reconciliation of output and input VAT
Copies of VAT returns filed
MTD-compatible digital records are increasingly expected, so prepare your spreadsheet or software export accordingly.
Prepare schedules of:
Fixed assets (with costs and acquisition dates)
Stock and inventory levels at year-end
Accurate asset data supports capital allowance claims and correct depreciation/reflection in accounts.
Include details of:
Business loans and overdrafts
Lease agreements
Finance arrangements
These affect interest deductions, liabilities and disclosures.
Provide:
Partnership or shareholder agreements
Contracts for long-term projects
Insurance policies
These help with correct accounting treatment of future obligations.
If you are preparing personal accounts or Self Assessment:
P60s and P45s
Bank and savings interest statements
Dividend income
Rental property details (income, expenses, mortgage interest adjustments)
Pension contributions
Gift Aid donations
Capital gains and disposals
Being organized reduces the risk of missing taxable events.
If you use accounting software:
Provide access or export reports
Ensure data is up to date and reconciled
Include links or files for online sales platforms, payment processors or merchant accounts
Digital exports save time, reduce manual entry and minimise risk of human error.
To complete your accounts, your accountant may ask:
Have all business bank accounts been included?
Are there outstanding invoices or bills?
Have you started or ceased trading during the period?
Have any assets been bought, sold or disposed of?
Have there been any changes to ownership or structure?
Preparing answers to these ahead of time helps the process run smoothly.
Keep records organised throughout the year rather than waiting until deadlines approach
Use digital tools or software that integrates with HMRC and MTD requirements
Label scanned documents clearly by type and date
Separate personal and business finances — this simplifies reconciliation
Provide notes for any unusual or one-off transactions
Good housekeeping during the year makes year-end preparation much easier.
Preparing financial information can feel overwhelming, especially alongside running your business.
