It is important to remember that net pay illustrations are often based on assumed information. We do our best to be as accurate as possible, but in some cases, we do not have all the information, like your tax code or your previous income.
We’ve designed our calculator to be as comprehensive as possible, but there will always be cases where something is missing. In this case, our business managers are happy to talk you through your circumstances and provide an exact calculation if you contact them.
Your Tax Code
An incorrect tax code used for the illustration can throw the results significantly. We won’t know your tax code until you send us your records (P45, P60 etc.). The tax code you think you are on may also be incorrect if your previous employer failed to update your records.
Some umbrella companies will alter the tax code to give you a higher take-home pay figure. At SmartWork, we work with a standard tax code 1250L that gives you a £12,500 personal allowance.
In our calculator, you can adjust your tax code if you know what it is. If you are a Scottish taxpayer, please let us know, as this can alter your results as well.
Missing P45/P60 Form
You may notice a significantly lower take-home pay if we haven’t got your P45 from your previous employer or P60 form if SmartWork is your first employer in the tax year. In this case, we have to put you on an emergency tax code that will result in a higher tax deduction. Don’t worry, though; once we have the correct tax code, the extra tax paid will be recovered in the subsequent months’ payroll.
Weekly or monthly illustrations
Depending on your weekly or monthly payment frequency, your net pay calculation may show 48 or 52 working weeks. In a monthly illustration, we calculate the average working days to be 20 days per month, so if you work less or more, that will result in your net pay being slightly different. The weekly take-home pay illustration, on the other hand, is based on 48 working weeks, taking into account bank holidays and time off work.
Your annual earnings
Umbrella pay illustrations are based on an annual income as in the whole tax year on that specific contract. As a contractor, your agreement may not last the entire 12 months; you may take time off, go on a holiday etc., and these will all affect your net take-home pay.
HMRC will assume that your contract rate is what you’ll earn for the whole year. For this reason, if you stop working early in the year, you may find that you have been deducted too much tax. This can be recovered at the end of the year.
Most umbrella companies will pay your holidays in advance, meaning that it’s included in your pay. If you choose to have your holiday pay accrued, it is retained for a later withdrawal. The overall effect on your net pay will be evident as it will miss the additional payment in your pay.
The Government requires every employer to enrol their employees into a pension scheme after 12 weeks. You can opt out, but if you don’t, this will show in your net pay as it decreases in line with the deductions made.
Most umbrella companies leave pension out of their illustrations as most contractors opt-out, and it shows a higher net take-home pay, which looks better. At SmartWork, we included a column to show you how Auto-enrolment will impact your net pay.
Like pension deductions, most umbrella companies will go for a better looking net pay by including expenses in their illustration, even though not everyone can claim. Again, we designed our calculator for transparency so you can see your net pay with or without expenses, so you know what you can expect.
It is important to note that all umbrella companies are all bound by the same employment laws and must deduct the same tax and NI percentages. Their quotes should only differ by the amount their margin varies.
How can SmartWork help?
