Tax trainees spend a lot of their first year preparing returns from information clients send in. A VAT return reports the VAT a business has charged and paid each quarter. A corporation tax computation turns a company’s accounting profit into taxable profit, because the tax rules treat some costs differently from the accounts.

Example. A company spends £5,000 taking clients to dinner. It is a real business cost in the accounts, but tax rules don’t allow it, so it is added back to profit before the tax is worked out.

Key words

VAT return
A form a VAT-registered business sends to HMRC, usually every quarter, showing the VAT it charged, the VAT it can reclaim, and the difference to pay or be repaid.Example: Box 1 VAT on sales £37,280 − Box 4 VAT reclaimed £14,900 = Box 5 £22,380 to pay.
Zero-rated
For VAT: a type of sale that is taxable, but at a rate of 0%. No VAT is charged, but the business can still reclaim VAT on its costs.Example: Goods exported outside the UK are zero-rated.
Exempt
For VAT: a type of sale that is outside VAT. No VAT is charged, and VAT on related costs usually cannot be reclaimed.Example: Insurance is exempt from VAT.
Taxable total profits
A company’s accounting profit after the tax adjustments (adding back disallowed costs and deducting capital allowances). Corporation tax is charged on this figure.Example: Accounting profit £412,000 + additions £44,900 − capital allowances £55,000 = taxable total profits £401,900.
Capital allowances
The tax rules’ version of depreciation. They decide how much of an asset’s cost can be taken off taxable profit, and when.Example: A company buys a £55,000 machine. The annual investment allowance lets it deduct all £55,000 from taxable profit in the year of purchase.

How a senior would approach it

  • VAT: sort every item first. Standard-rated, zero-rated, exempt, or blocked (VAT paid that can’t be reclaimed). Zero-rated and exempt items both have no VAT, but they still go in the sales or purchases totals (boxes 6 and 7).
  • The VAT return boxes you’ll use most: Box 1 VAT due on sales, Box 3 total VAT due, Box 4 VAT reclaimed on purchases, Box 5 net VAT to pay (or reclaim), Box 6 total sales excluding VAT, Box 7 total purchases excluding VAT.
  • Corporation tax starts from accounting profit, then adjusts it to taxable profit. Add back costs the tax rules don’t allow (depreciation, client entertaining, fines). Deduct the tax version of depreciation instead: capital allowances.
  • Staff entertaining is usually allowable, but client entertaining isn’t. This catches a lot of people out.
  • Show your workings line by line, so your senior can review the computation quickly.
