When Company C1 pays dividend, should it pay tax?
Corporations should pay Corporation Tax on their profits which is now 20%. This tax is paid before paying any dividend!
When shareholder S1 receives dividend, should it pay tax?
If the shareholder's overall dividend income is between £37,400 and £150,000, then that shareholder has to pay 32.5% tax on his dividend. If the dividend income is less than £37,400 then 10% is the tax.
hmm, if £1000 is your Company's profit you have to pay £200 for corporation tax. So on the remaining £800, you have to pay 10% of it (assuming you're the shareholder) for shareholder dividend which would be £80. Therefore, at the end what you will get is £720 which means overall you have paid is 28% tax whereas if that profit was to be paid via PAYE, then 40% tax should have been paid assuming the shareholder's gross income is over £37,400.
So the tax saving you would make in this way would be 12% on your income above £37,400.
