Irish Business & Self-Employed Calculators

Running a business or working for yourself in Ireland brings extra tax obligations: preliminary tax, self-assessment, VAT, and the employer PRSI charge if you hire. Pricing decisions also need a margin/markup view and a break-even check. The calculators in this hub work through each one — work out preliminary tax against the prior-year liability, model VAT on either side of a transaction, and size the pricing or break-even point that makes a product viable.
