Accountancy Terms Explained for Startups

UK startups encounter 12 core accountancy terms within their first trading year. Understanding these terms prevents compliance penalties, improves cash management, and supports better business decisions. Aqua Accounting, an ICAEW Registered Member Firm based in Newcastle upon Tyne, has supported North East businesses for over 13 years. This guide covers 10 essential accountancy terms explained for startups, from balance sheets to director’s loan accounts.

What Is a Balance Sheet?

A balance sheet is a financial statement showing what a company owns, what it owes, and what it is worth at a specific date. The document lists three categories: assets (cash, stock, equipment, property), liabilities (loans, unpaid bills, tax owed), and shareholder equity. Companies House requires all limited companies to file a balance sheet annually as part of their Company Accounts. A healthy balance sheet shows assets exceeding liabilities. Startups use this document to secure funding. Investors and lenders review it to assess financial stability before committing capital. According to ICAEW guidance, a balance sheet provides a snapshot of financial position at a single point in time, distinct from a profit and loss account which measures performance across a period.

What Is a Profit and Loss Account?

A profit and loss account is a financial report showing total income minus total costs over a specific period. The statement reveals whether a business generated a profit or a loss. Revenue appears at the top. Direct costs follow. Operating expenses come next. The final figure represents net profit or net loss. Limited companies submit this document to Companies House annually. Startups review their P&L monthly to track performance trends, identify rising costs, and adjust pricing strategy. The P&L does not show cash position. That information appears on the cash flow statement. Our Business Accounting Advisory service helps Newcastle startups interpret P&L data and act on the findings.

What Is Cash Flow?

Cash flow is the movement of money in and out of a business during a specific period. Positive cash flow means more money enters than leaves. Negative cash flow means outgoings exceed income. According to a 2023 UK Business Bank study, 60% of UK small businesses experience cash flow difficulties within their first 24 months of trading. Startups monitor cash flow across three categories: operating activities (sales receipts, wages, supplier payments), investing activities (equipment purchases, asset sales), and financing activities (loans, share issues, dividends). Effective cash flow management requires invoicing promptly, chasing overdue payments, and maintaining a cash reserve covering 3 to 6 months of operating costs. Our Bookkeeping Services help Newcastle startups track cash movement accurately and identify trends early.

What Is a VAT Return?

A VAT return is a quarterly or annual submission to HMRC showing VAT charged on sales minus VAT paid on purchases. Businesses with a taxable turnover above £90,000 (the 2024/25 threshold) must register for VAT. The return calculates the difference between output VAT (charged to customers) and input VAT (paid to suppliers). If output VAT exceeds input VAT, the business pays the difference to HMRC. If input VAT exceeds output VAT, HMRC issues a refund. Under Making Tax Digital, VAT-registered businesses submit returns through compatible software. Paper returns are no longer accepted. Filing late incurs a £200 penalty plus surcharges on VAT owed. Our VAT Services ensure full compliance with HMRC requirements.

What Is a Self Assessment Tax Return?

A Self Assessment tax return is an annual report to HMRC declaring personal income from all sources. Company directors, sole traders earning over £1,000, and individuals with untaxed income must file one. The deadline for online submission is 31 January each year. Late filing triggers an automatic £100 penalty. HMRC issues these returns to collect Income Tax and National Insurance contributions on earnings not taxed at source. Directors typically report salary, dividends, rental income, and any other personal income on the same form. The return covers the tax year ending 5 April, with payment due by 31 January. Our Tax Returns / Taxation service manages this process for business owners across the North East.

What Is Corporation Tax?

Corporation Tax is a tax on the profits of UK limited companies, set at 25% for profits over £250,000 and 19% for profits under £50,000 in the 2024/25 tax year. Companies with profits between £50,000 and £250,000 pay a tapered rate calculated by HMRC. The tax applies to trading profits, investment profits, and chargeable gains. Limited companies must file a Corporation Tax return (CT600) with HMRC within 12 months of their accounting period end. Payment is due 9 months and 1 day after the accounting period end. Filing late incurs penalties starting at £100, rising to £400 for delays exceeding 6 months. Aqua Accounting provides Corporation Tax compliance services as part of our ICAEW-regulated practice.

What Is a Confirmation Statement?

A confirmation statement is an annual filing with Companies House confirming a company’s registered details remain accurate. Every limited company and LLP must file one at least once every 12 months. The statement verifies registered office address, directors, shareholders, share capital, People with Significant Control, and SIC code. Filing costs £13 online or £40 by post. Companies House may strike off companies that fail to submit within 14 days of the deadline. The confirmation statement replaced the annual return in June 2016. Startups often handle this filing alongside their Limited Company Formations obligations during their first trading year.

What Is the Difference Between Gross Profit and Net Profit?

Gross profit is revenue minus the direct costs of producing goods or services, while net profit is gross profit minus all other operating expenses including overheads, interest, and tax. The two figures measure profitability at different stages of the business. A startup selling £100,000 of products with £40,000 in direct costs has a gross profit of £60,000. If overheads, interest, and tax total £45,000, the net profit is £15,000. Gross profit margin (gross profit divided by revenue, expressed as a percentage) shows production efficiency. Net profit margin (net profit divided by revenue) shows overall business efficiency. Investors examine both figures to assess cost control, pricing strategy, and scalability.

What Are Accruals and Prepayments?

Accruals are expenses incurred but not yet invoiced or paid, while prepayments are costs paid in advance for goods or services not yet received. Both adjustments ensure accounts reflect the correct accounting period for income and expenditure. A startup paying £6,000 for annual insurance in January records £500 per month as a prepayment, matching the cost to each trading month. An unpaid December utility bill estimated at £300, received in February, appears as a £300 accrual for December. Accrual accounting matches income and costs to the period they relate to, giving a more accurate profit figure than cash accounting. ICAEW Chartered Accountants apply these adjustments during year-end Company Accounts preparation.

What Is a Director’s Loan Account?

A director’s loan account is a record of money a company director borrows from their own company, or money they lend to it, outside of salary, dividends, and expense reimbursements. When a director takes money from the company that is not salary, dividend, or expense repayment, it creates a loan. If the loan balance exceeds £10,000 at the year-end, the company must report it to HMRC on form CT61A. Loans written off trigger Income Tax and Class 1 National Insurance liabilities for the recipient. If a director’s loan account remains unpaid 9 months after the accounting period end, the company pays Section 455 tax at 33.75% (2024/25 rate). This tax is repayable once the loan is cleared. Proper record-keeping prevents unexpected tax charges and penalties.

Frequently Asked Questions

What is the difference between a bookkeeper and an accountant?

A bookkeeper records daily financial transactions, while an accountant analyses financial data, prepares tax returns, and provides strategic business advice. Bookkeepers handle sales invoices, purchase receipts, bank reconciliation, and payroll processing. Accountants interpret financial data, file returns with HMRC and Companies House, and advise on tax planning, business structure, and growth strategy. Most UK startups need both functions working in sequence. A bookkeeper manages routine recording, and a chartered accountant handles compliance and strategy. Explore our Bookkeeping Services and Business Accounting Advisory for combined support.

What is MTD?

Making Tax Digital (MTD) is an HMRC initiative requiring businesses to maintain digital records and submit tax returns through compatible software. MTD for VAT became mandatory for all VAT-registered businesses in April 2022. MTD for Income Tax Self Assessment begins in April 2026 for sole traders and landlords with income above £50,000, and April 2027 for those with income between £30,000 and £50,000. Businesses must use HMRC-recognised software including Xero, QuickBooks, or FreeAgent. Paper records and spreadsheets alone no longer meet compliance standards. Aqua Accounting operates as an MTD-compliant, ICAEW-registered firm supporting Newcastle startups through every digital filing requirement. Our VAT Services cover MTD for VAT submissions.

What is a PAYE scheme?

A PAYE (Pay As You Earn) scheme is an HMRC system where employers deduct Income Tax and National Insurance contributions from employee wages before payment. Any company paying employees above £123 per week in the 2024/25 tax year must register for PAYE. Deductions include Income Tax, employee National Insurance, employer National Insurance, student loan repayments, and pension contributions. Employers submit Real Time Information (RTI) reports to HMRC on or before each payday. Our Payroll Services handle PAYE registration, weekly or monthly processing, payslip generation, and year-end reporting for startups across the North East.

What is a dividend?

A dividend is a payment from a company’s post-tax profits to its shareholders, taxed separately from salary under the UK dividend tax system. Directors of limited companies often pay themselves a combination of low salary (below the National Insurance primary threshold) and dividends, reducing their overall personal tax liability. The dividend allowance for 2024/25 is £500. Above this amount, dividend tax rates are 8.75% at the basic rate, 33.75% at the higher rate, and 39.35% at the additional rate. Dividends cannot exceed available retained profits. Companies must issue dividend vouchers and record board meeting minutes declaring each payment. Our Tax Returns / Taxation service manages dividend reporting for company directors.

What is a fiscal year?

A fiscal year is a 12-month accounting period used for financial reporting and tax calculations. The UK government’s fiscal year runs from 6 April to 5 April the following year. Corporation Tax uses a company’s own accounting period, which may differ from the government fiscal year. HMRC Self Assessment deadlines align with the fiscal year ending 5 April. Startups registered with Companies House choose their accounting reference date, typically set to the last day of the month in which they incorporated. Aligning the company accounting period with the fiscal year simplifies reporting, reduces administrative complexity, and minimises the risk of filing errors. Our Company Accounts team advises startups on selecting the optimal accounting period.

These accountancy terms explained for startups form the foundation of UK financial compliance.
