Need to find out the tax rate, the resident and non-resident tax, 180 days etc.
if stay more 183 consider resident tax..tax rate as below..
Tax rates for non-resident individuals
Your employment income is taxed at 15% or resident rate,
whichever gives rise to a higher tax amount.
How about the withholding tax?
Payment for services rendered
Where payment is made to a non-resident company for the installation of equipment,
technical support services, training, consultancy or other services provided
by the non-resident company, withholding tax is applicable on the service fees
attributable to work done in Singapore.
If the payer pays for monthly allowance of the non-resident company's employees who
are sent to Singapore to perform the services, withholding tax is applicable on
the allowance because the monthly allowance is actually additional service fees paid
to the non-resident company.
However, if the non-resident company provides the services via electronic means
overseas (e.g. internet presentation, email and telephone) without sending staff to
Singapore, the services are rendered outside Singapore and withholding tax is
Look at this..it seem like if stay less then 183 days, and if the payment already deduct the withholding tax, there is no tax issue..
As his physical stay in Singapore is less than 183 days, he will be treated as a non-resident for tax purposes. If he is only in receipt of such fee for the year, he does not need to file the tax form as you have deducted 15% withholding tax. If he has received a tax form / tax bill, please forward the Confirmation of Payment for our review.
Whether you need to withhold tax would depend on whether the visiting professional needs to pay tax in Singapore under the provisions of the tax treaty. For example, under the tax treaty between Singapore and United Kingdom, the income derived by the non-resident professional from Singapore will be tax exempt provided:
a. He does not have a fixed base regularly available to him in Singapore for the purpose of performing his activities; or
b. He is not present in Singapore for not more than 183 days in any period of 12 months commencing or ending in the fiscal year concerned
If he (with no fixed base in Singapore) is in Singapore for a 5-month engagement in year 2008, his income derived during that period will be tax-exempt for Year of Assessment (YA) 2009 (See Chart 1).
Chart 1: Tax Exempt for YA 2009 as presence in Singapore < 183 days
However, if he comes to Singapore for another 5-month engagement in year 2009, his income derived from the first engagement in 2008 will then be taxable in Singapore in YA 2009 as he would have been present in Singapore for periods exceeding the aggregate of 183 days in the first 12-month period commencing from 1 July 2008 (See Chart 2).
His income derived from the second engagement in 2009 will be taxable in Singapore in YA 2010 as he would be present in Singapore for periods exceeding the
aggregate of 183 days in the second 12-month period ending 31 July 2009 (See Chart 2).
Chart 2: Taxable for YA 2009 and YA 2010 as physical presence in Singapore > 183 days in first 12-month period from 1 Jul 2008 to 30 Jun 2009 and second 12-month period from 1 Aug 2008 to 31 Jul 2009 respectively
