Why your tax bill doesn't match your profit

Two sets of rules, one set of transactions

Your financial statements measure performance under accounting standards. The tax computation measures what the law says is taxable. The same transactions go in, different rules are applied, and different answers come out.

A tax computation therefore does not start from scratch. It starts with the accounting profit and adjusts it — adding back what is not deductible, and replacing some accounting figures with statutory equivalents.

What typically gets added back

These are costs that are real, properly recorded and correctly in your accounts, but which the law does not allow as a deduction, or allows only in part.

Depreciation

The largest adjustment for most companies. Depreciation is an accounting estimate, so it is added back in full. In its place the law gives capital allowances, covered below.

Private and personal expenses

Anything not wholly and exclusively for the business. Where a cost has both a business and a private element — a vehicle, a phone, travel — only the business portion is deductible, and the split has to be supportable.

Entertainment

The deduction is restricted, and the restriction differs depending on who was entertained and why. Staff entertainment, client entertainment and promotional events are not treated identically, which is why the ledger description matters. A single catch-all "Entertainment" account makes this harder than it needs to be.

Provisions and estimates

A general provision — for doubtful debts, for stock obsolescence, for some future cost — is an accounting judgement rather than an incurred expense, and is added back. Specific amounts, properly identified and evidenced, are treated differently from general ones.

Fines, penalties and non-approved donations

Fines and penalties are not deductible. Donations are deductible only where the recipient is an approved body and the paperwork is in order — a receipt from a worthy cause is not automatically enough.

Capital allowances instead of depreciation

Having added depreciation back, the law gives its own relief for qualifying assets. The rates and categories are set by statute and change from time to time, so they should be confirmed for the year in question rather than assumed from last year's computation.

Two practical points. An asset generally has to be in use in the year for the claim to arise, so buying in December and commissioning in February matters. And capital allowances are claimed, not automatic — if the asset register is incomplete, the claim is incomplete with it.

Why a loss year still needs attention

"We made a loss, so there's nothing to file" is one of the more expensive misconceptions. A company files its return whether or not it traded or profited.

More importantly, unabsorbed losses and unabsorbed capital allowances carry forward against future profits — but only if they are properly computed and claimed in the year they arise. A loss year handled casually can quietly cost you relief in a profitable year later. Carry-forward is also subject to conditions, including continuity of ownership, which is worth understanding before any change in shareholding.

What this means in practice

Your tax cash-flow is not your profit. Because the computation starts from profit and then adjusts, tax payable can be materially higher than a glance at the P&L suggests — most often where a company has spent heavily on assets and is carrying large depreciation. This is precisely why the CP204 estimate, submitted before the year it relates to, is hard to get right without doing some of the thinking in advance.

Ledger descriptions do real work. Most of the adjustments above depend on knowing what a cost actually was. A well-analysed set of accounts produces a defensible computation quickly. A single "Sundry expenses" account produces questions.

Evidence has to exist at the time. The business proportion of a mixed cost, the specific basis of a provision, the approved status of a donee — these are supported by records kept during the year, not by an explanation offered afterwards.

Where we fit

Our work is the bookkeeping underneath it: accounts analysed so that deductible and non-deductible costs are distinguishable, a fixed asset register that can actually support a capital allowance claim, and figures current enough to be useful before the year ends rather than months after. That is the raw material every tax computation is built from.
