Where you purchase any type of marketing product, such as leaflets/fliers, posters or banners to advertise your business, you can claim the full cost as an expense on your tax return.
For most self-employed individuals, some form of advertising is essential, and this includes adverts in newspapers, Facebook adverts or even charges for putting a poster up in your local shop!
As always, keep a copy of the receipt and enter this as an expense on your tax return documents. The full amount can be claimed against any profits or income which your business has made during the applicable tax year.
