The books and the return are different documents
Accounting profit is computed under accounting rules; taxable income is computed under tax rules. They start from the same transactions and they are not the same number, and neither one is a corrupted version of the other.

What it is for
Almost every confusion in tax accounting starts here. Somebody sees a profit of 240,000 in the accounts and a different figure on the return and assumes an error or a trick. Both are correct: they answer different questions set by different rule-makers for different purposes, and the reconciliation between them is a normal piece of work rather than an admission.
How to think about it
Start from accounting profit. Add back anything the accounts deducted that the tax rules do not allow. Subtract anything the tax rules allow that the accounts did not deduct. What you have is taxable income, and you keep the workings, because that reconciliation is what anybody reviewing it will ask for.
Worked example
Accounting profit from the booksWhere the reconciliation starts.
Add back amounts the tax rules disallowThe accounts were right to deduct them; the return may not.
Subtract reliefs the tax rules giveAllowed on the return and not in the accounts.
The result is taxable incomeA different number, correctly.
Your turn
Name where a reconciliation to taxable income begins.

The trap
Assuming one of the two figures must be wrong. They are computed under different rules by design, and an accountant who tries to make them agree has misunderstood what each is for.
