THE strike at the South African Revenue Services has ended and taxpayers can now go and file their tax returns.
Public Servants Association (PSA) spokesperson Manie de Clercq said an agreement was expected to be signed this week.
"Everything is going well at Sars branches across the country. Workers are at work. The week-long strike has ended," De Clercq said.
Thousands of National Heath and Allied Workers Union (Nehawu) and PSA members had been on strike over salary increases during the past week.
With the tax filing system at its peak, long queues were the norm at Sars branches nationwide. The deadline for tax returns submission is Friday.
Electronic submission are to be done by November.
The hardest hit was the tax collector's customs and immigration offices at the borders.
Individuals travelling into the country could not enter at border gates, and trucks delivering goods were stuck at the borders too.
Both unions were demanding a 13percent salary increase across the board.
Sars had offered 7percent, then revised the offer to between 9 and 11percent on a sliding scale.
The unions initially rejected the offer, but the workers decided to resume work today.
Sars stood by its decision taken last week that no further concessions will be made to its current wage increase proposal and that a no-work-no-pay rule applied.
