I'm going to answer your '£35,000' question by working through the calculation to avoid any uncertainty.
Your company makes £46,900 profit before it pays you anything (or any tax) - you'll see why I chose that figure later. It pays you a salary of £7,475 which means your NI record gets credited for the basic pension, and uses your tax free personal allowance (which cannot be used by dividends) - the company will pay about £56 in employers NI leaving it with profit of £46,900 - £7,475 - £56 = £39,369. It will pay tax at 20% on this figure, £7,874, leaving net profit of £31,495. It pays you all of this in dividends which is a gross dividend of £34,995 less dividend tax of £3,500.
You pay 10% tax on dividends within the £35,000 basic rate tax band, which is equal to the dividend tax credit received, so effectively you pay no tax on the net dividend of £31,495. You have also received a salary of £7,475 less about £30 NI, so you receive £38,940 of the total £46,900 profit.
Compare this with a self employed person with the same gross income who pays 20% of (£46,900-£7,475) = £7,885 tax and Class 4 NI at 9% of earnings between £7,225 and £42,475 (£3,173) plus 2% on the remaining (£46,900-£42,475) (£89), only keeping £35,753 of her hard-earned profit.
Apologies in advance for any errors, it is a bit late and I may not be copying them across correctly from my spreadsheet
