You simply enter amounts from the IRP5 such as codes 3810, 4474, 4005 etc and WinTax shows your claims and medical aid contribution tax credits in an instant. This screen allows you to calculate medical deduction claims for the most complex medical aid contribution claim scenarios. While producers of other tax software programs seem unable to get many of these complicated medical claim calculations correct and even SARS’s seems to be struggling with their own medical claim calculations, WinTax gets them 100% right every time (including the 7.5% taxable income rule). Play around with this screen in WinTax for a few minutes and you will have a better understanding of how the Medical Aid Contribution laws work. Allowable claims for contributions and medical expenses automatically converted to tax credits in WinTax.

Capped amounts, for medical aid fund contributions, have been abolished since 1st March 2012 and replaced by tax credits. At first glance the new tax credit system appears simpler than the old capped amount system but, if you look deeper, the new “non-refundable” tax credit system is even more complex but WinTax handles all calculations with ease – including the most complex contribution splits between employer and employee!  Not only does WinTax show you how and where, in the calclation, these tax credits affect the assessment, WinTax also shows you how, and where, these calculations affect daily, weekly and monthly salary-source calculations as well as on annual IRP5’s.

WinTax caters for the latest laws regarding the taxation of lump sums taken from Retirement Funds, including those taken at resignation, severance packages, retrenchment withdrawals, retirement, multiple lump sums in multiple years or a single year etc. The new “accumulative” method of taxing these lump sums is more than complex but WinTax handles it all with the greatest of ease.

WinTax Pro also caters for the admin and taxation of Trusts where you can store all Trust info like Capital Gain assets and sales, trustee’s and beneficiary’s details, details of distributed income (who got what and how much), income and expenditure statements which cross-check to see that you have not paid out more (interest, exempt, taxable, Capital Gain income etc) to the beneficiaries than the Trust earned.  All tax calculations including Provisionals etc, done for you. Direct your printouts to the printer or to a word processor where 90% of the financial statement is laid out for you.

Simple Estate Duty Estimator

A quick calculator in WinTax2018 to estimate estate duty and executor’s fees for a client by entering no more than 7 or 8 amounts. On-screen HELP tells what to enter and where. Ever wanted a simple calculator that you can use to enter half a dozen figures to calculate and show an estimate of Estate Duty and Executor’s fees without using a complex 20-page spreadsheet-program? Using such a complex 20-page program often involves spending ages trying to get all the relevant information out of the client just to get an estimate of duty and fees. These financial planners want a quick 10-minute tool to be able to show a client whether they would be facing death-duty fees of R1,000 or R1,000,000 and how some simple estate planning could save high net-worth clients paying the state and executors a fortune. The new Estate Duty Estimator in WinTax is just what many tax planners and financial planners have been looking for and they will agree that this update adds extra value to WinTax. Of course any figures in the Estate Duty Estimator can be saved in the WinTax database, under the client’s name, retrieved, edited and printed (with a disclaimer that the client can sign to protect you).


CGT Calculator

WinTax remains the only tax software in South Africa with a comprehensive Capital Gains Tax register and calculator for both local and foreign capital gain transactions.

WinTax CGT calculator will show you which of the three methods allowed by SARS would give you the lowest Capital Gain amount for tax. Make a mistake by choosing the wrong option with a CGT calculation and it could cost you plenty. This calculator in WinTax exposes SARS’s costly errors with CGT calculations on assessments.
