UK accounting basics & Making Tax Digital (MTD)
Solid books make tax filings and decisions easier. This guide outlines core ideas—record-keeping, reporting cycles, and MTD—in plain English. Always confirm current requirements on GOV.UK and with HMRC or your adviser.
Core building blocks
Most UK businesses track money in (sales), money out (purchases and expenses), and obligations (VAT, PAYE, Corporation Tax). Accounting software helps categorise transactions, reconcile the bank, and produce reports—but the underlying discipline is keeping complete, timely records.
Year-end and reporting
After your accounting year ends, you typically:
- Close the books (adjustments, accruals, depreciation where relevant).
- Prepare statutory accounts if you are a company.
- File tax returns—Corporation Tax or Self Assessment depending on structure.
Dates depend on your company year or tax year; missing deadlines can mean penalties.
Making Tax Digital (MTD)
MTD for VAT: VAT-registered businesses must keep digital VAT records and file VAT returns under MTD rules using compatible software (or bridging software where allowed). Overview: Making Tax Digital for VAT.
MTD for Income Tax: being introduced for Income Tax Self Assessment from 6 April 2026 in stages, using qualifying income thresholds (£50,000 then £30,000 then £20,000 mandation steps—see GOV.UK). Read our MTD for Income Tax guide and HMRC’s Use Making Tax Digital for Income Tax.
MTD does not replace the need for accurate supplier and bank reconciliation—if anything, consistent digital processes matter more.
Bank feeds and reconciliation
Cloud tools often import bank transactions automatically. Reconciliation means matching those lines to invoices, bills, and receipts so the ledger reflects reality. Supplier statements and emails still need to be checked—especially where amounts or VAT do not match.
