What this assumes

The director takes the salary and dividends shown and has no other income; the full personal allowance (£12,570) applies, tapering above £100,000.

Company profit equals your tax-adjusted profit (no capital allowances or add-backs), with no associated companies and a non-Scottish/Welsh taxpayer.

Dividends can only be paid from retained profit after Corporation Tax — paying more is unlawful. Employer's/employee's NIC on salary and the HICBC are not calculated here.

Record each dividend as you declare it. Keep a dividend voucher and board minute for every one.

What is s455 tax?

If the loan account is overdrawn (the director owes the company) at year end and isn't repaid within 9 months + 1 day, the company pays s455 tax at 33.75% of the outstanding balance. It's refundable once repaid, but the cash is tied up meanwhile. A loan over £10,000 at any point may also create a taxable benefit in kind. Seek advice if overdrawn.

An estimate, not tax advice. Figures you enter drive the results.
