iPAYE balances payslips to the penny allowing values to be carried forward from one pay period to the next AND it has a Quick Tax calculator to answer questions such as … "How much do I have to earn if I want to take home £100 per day?"

Use iPAYE to answer all your payroll queries …
- Am I paying the correct tax and national insurance?
- How much net pay will I get next month?
- How much extra net pay will I get if I get that bonus or pay rise?
- How much gross pay do I need in order to achieve my target net pay?
- How has my net pay changed since year?
- Have I been given a correct P45 by my previous employer?

iPAYE fully complies with the HMRC Specifications for tax and NIC calculation. Small businesses may find iPAYE useful in managing employee payments and deductions prior to entering pay period information into HMRC Basic PAYE Tools (BPT-RTI).

Calculations can be printed and saved for an unlimited number of scenarios or employees.
Saved calculations can be recalled, viewed and printed.

iPAYE caters for tax years 2014/15, 2013/14, 2012/13, 2011/12, 2010/11 and 2009/10 and updates will be available during a tax year in response to statutory changes.

What's New in Version 2.10

iPAYE has been updated for the 2014/15 tax year.

In January 2014 the original author of iPAYE, David Langan, retired and asked us to look after his applications which we are honoured and delighted to do.

During the course of 2014 we will be busy working on a new version for the 2015/16 tax year which will be optimised for OS X Mavericks and include a lot of user interface improvements and changes.

Until then however please rest assured that we will be fixing bugs and any other issues.
