Accounting and Tax Setup for a New Small Business

Before software

Map the entity, taxes, filings, and dates

List the legal entity, owners, locations, employees or contractors, sales channels, and countries where the business operates or sells. Then ask a qualified professional which registrations, taxes, reports, and records apply. Income tax, corporation tax, sales tax, VAT, payroll, information returns, and local licenses follow different rules.

Create one compliance calendar with the responsible person, preparation date, statutory deadline, payment method, and evidence of submission. Do not rely only on reminder emails from a service. Access can fail, addresses change, and a provider may not cover every obligation.

Bookkeeping design

Use categories that answer business questions

A chart of accounts should be detailed enough to distinguish meaningful revenue, direct costs, operating expenses, assets, liabilities, equity, and tax balances without creating dozens of rarely used categories. Consistent rules matter more than elaborate naming. Write short notes for ambiguous categories and update them deliberately.

Choose cash or accrual accounting only after considering local rules and management needs. Cash records payments when money moves; accrual accounting recognizes income and costs according to the underlying transaction. Software settings do not decide what is legally permitted or appropriate.

Source documents

Preserve the evidence behind every important entry

Keep sales invoices, receipts, supplier bills, contracts, bank records, payment processor reports, payroll records, tax filings, asset documents, and explanations for adjustments. A bank feed shows that money moved; it may not show what was purchased, why it was business-related, or how tax should be treated.

Use a consistent filename or document identifier and link evidence to the transaction where possible. Preserve original currency, tax amounts, business purpose, and approval. Back up records in a format you can retrieve even if you leave a software provider.

• Transaction date and counterpart
• Amount, currency, and tax
• Business purpose
• Proof of payment
• Invoice or receipt
• Approval or contract where relevant

Monthly close

Reconcile accounts before reading reports

Match bank, card, loan, payment processor, and cash balances to independent statements. Resolve missing, duplicated, reversed, or delayed transactions. Review accounts receivable, accounts payable, tax balances, payroll liabilities, inventory where relevant, and owner transactions.

Only then use the profit and loss statement, balance sheet, and cash-flow view. A dashboard built on unreconciled data can be confidently wrong. Compare actual results with the previous period and budget, and investigate unusual changes rather than forcing reports to match expectations.

Professional review

Use an adviser for judgment, not data cleanup

Before the first filing period, ask an accountant or tax adviser to review entity treatment, registrations, accounting method, opening balances, owner transactions, payroll, indirect taxes, and record retention. Provide a concise business description and list the decisions you need, rather than sending an unexplained folder at the deadline.

Clarify responsibilities in writing: who records transactions, reconciles, prepares payroll, submits each filing, authorizes payments, and answers notices. Outsourcing preparation does not necessarily transfer the owner's or director's legal responsibility.
