South Africa August deadlines

For a year of assessment that starts in March, the first provisional tax payment is due on 31 August, or on the last business day before it when 31 August is a Saturday, Sunday or public holiday. The employer interim reconciliation covers the six months from 1 March to 31 August. National Women's Day, 9 August, is a public holiday, and the following Monday is one when it falls on a Sunday. Employers submit and pay the EMP201 for July by August 7, or the last business day before it, and VAT for a tax period ending in July is due by August 25, or the last business day of August on eFiling. Women's Day 2027 is Monday 9 August. August 7 is a Saturday, so the EMP201 is due Friday 6 August. August 31 is a Tuesday, so the first provisional payment is due that day.

Those dates in 2027

One of the dates named above does not fall on a working day in 2027 under the South African public calendar. A fixed calendar date advances through the week year by year, so this resolution holds for 2027 only.

South Africa reporting cycles and business-day rules

SARS sets several South African tax dates by business days. The EMP201 employer declaration and any payment are due by the 7th of each month; if the 7th falls on a weekend or public holiday, they are due by the last business day before it. A VAT vendor submits the return and pays on or before the 25th of the month after the tax period ends, or by the last business day of that month if registered for eFiling; where the 25th is not a business day, the business day before it applies. For years of assessment starting in March, the first provisional tax payment is due on 31 August, or the last business day before it if 31 August falls on a Saturday, Sunday or public holiday, and the second by the last business day of February. Under the Public Holidays Act 36 of 1994, when a public holiday falls on a Sunday, the Monday following is a public holiday.

August 2027 working days compared by country

Working-day counts vary across countries because each country observes its own public holidays. The table below shows August 2027 under 11 of the site's 25 holiday calendars; the summary above gives South Africa's own count.

How August 2027 compares year over year

August 2026 had 20 working days, so August 2027 has 1 more working day year over year. On the surrounding months, July 2027 has 22 working days and September 2027 has 21. Looking forward, August 2028 has 22 working days under the same South African public holiday calendar.

Using this calculator in South Africa

The 21 business days in August 2027 are the count to use when you plan South African work that runs on working days: payroll runs, supplier payments, invoice due dates and filing reminders. The count leaves out Saturdays, Sundays and the South African public holidays in this site's data that fall in the month.

How August 2027 is shaped

The headline count answers how many working days August 2027 contains. It does not answer where they sit, and for anything measured in consecutive days rather than cumulative days that second question is the binding one. What follows is derived entirely from the South African public holiday calendar and a working week that treats Saturday and Sunday as the weekend, with no assumption about how any particular obligation behaves.

The middle month of the third quarter

August runs 31 days and sits in the middle of Q3, so it opens and closes nothing: no quarter, no half, no year. That makes it the month whose working-day count is least likely to be checked and most likely to be assumed. In a common year August shares its weekday alignment with February and March, which is the widest such group in the calendar.

In August 2027 that comes to 21 working days across 31 calendar days, against 22 in July 2027 and 21 in September 2027.

The month opens across a weekend

The 1st of August is a Sunday, a weekend day under the South African public calendar, whose week runs against a Saturday and Sunday weekend. Nothing that settles on working days moves on it. A month that opens this way loses its first working day to the calendar before any holiday is counted, and monthly cycles keyed to the 1st all resolve forward to the same date, which concentrates them.

The month's first working day is Monday, August 2, and August 2027 carries 21 working days in total.

Five working stretches

August splits into five working stretches. That is the ordinary shape of a month whose only interruptions are its weekends, and it means the month's internal boundaries are all predictable a year in advance: nothing here depends on a holiday date moving.

The working days of August 2027 arrive in stretches of 5, 4, 5, 5, and 2 days. The longest unbroken stretch runs five days, from August 2 to August 6. A task needing more consecutive working days than that cannot be completed inside a single stretch, whatever the month's total looks like.

The month is front-loaded. It opens with five consecutive days and closes with two, so capacity thins toward the end. Work deferred out of the first stretch arrives in a shorter one, which is how a schedule that looked comfortable in week one stops fitting.

Three weekdays occur five times

A 31-day month contains four full seven-day cycles and three days over, so exactly three weekdays occur five times and the other four occur four times. In August 2027 the three are Sunday, Monday, and Tuesday. Which three it is follows entirely from the weekday the month opens on, which is why the working-day count of a 31-day month moves year to year even when its holidays do not.

Only Monday and Tuesday among them are working days, so part of the surplus is absorbed by the Saturday and Sunday weekend and never reaches the working total. That split is why two months of the same length can carry different working-day counts without any holiday being involved.

One closure, and where it lands

August 2027 carries a single South African public closure on a working day: National Women's Day on Monday, August 9. A holiday's cost to a month is not only the day it removes; it is also where the removal falls, because the same closure can extend an existing break or cut a working stretch in half.

It sits directly beside a weekend rather than inside a working week, so it extends an existing break instead of creating a new one. That is the cheapest position a holiday can occupy: the month loses a day but keeps its shape.

five working days pass before the closure and 16 follow it, which puts the break just short of the month's midpoint. A closure near the middle divides the month into two usable halves rather than trimming one end of it.

The closures around this month

August 2027 carries one South African public closure of its own, and the months on either side add their own. Where a deadline sits close to a month boundary, the closure that moves it is as likely to be outside the month as inside it.

Looking outside the month, the last was Youth Day on June 16, 2027, 46 calendar days before August began and the next is Heritage Day on September 24, 2027, 24 calendar days after it ends.

Across the whole of 2027 the South African public calendar puts ten closures on working days, of which one falls in August. That ratio, rather than the raw count, is what tells you whether a month is carrying more than its share of the year's downtime.

An early-week close

August runs out after the second working day of its last week. Most of that week belongs to the next month, so the tail of August 2027 is unusually thin: two working days carry whatever the month-end process needs, and the week's remaining capacity is not available to this period.

The last working day of August 2027 is Tuesday, August 31. Counting back from there, the third-to-last is Friday, August 27, four calendar days before the month closes.

The middle month of the quarter

August is the middle month of Q3. Middle months carry the least visibility in a quarterly cycle: the opening month sets expectations and the closing month is where they are settled, so a shortfall here is the one most likely to be noticed late.

Across the whole quarter there are 64 working days, of which 21 fall in August. The other two months carry July 2027 with 22 and September 2027 with 21. It sits between the other two, which makes it the month where a quarterly plan is least likely to be thrown off by the calendar alone.

The week's first working day is the scarcest

The first working day of the week is the one August gives least often. Anything anchored to the start of the working week (a weekly kickoff, a Monday-morning cutoff, a start-of-week batch) fires fewer times this month than the calendar count suggests, because a closure has taken one of them out.

Counted as worked rather than as occurring, August 2027 gives Monday 4, Tuesday 5, Wednesday 4, Thursday 4, and Friday 4. A weekly commitment pinned to a particular weekday fires that many times in the month, which is the number a rota needs and not the one the calendar shows.

Where the month sits in the year

August sits in the middle of 2027 by working-day count under the South African public calendar. The middle of that ranking is where a month's total is least informative on its own, because a mid-ranked month can be a long month carrying closures or a short one carrying none, and the two need different plans.

2027 carries 251 working days in total under the South African public calendar. The longest month of the year is July 2027 with 22 and the shortest is March 2027 with 20, a spread of 2. August ranks 6th of the twelve with 21.

South Africa closures across the year

A month's working-day count only means something against the country's whole calendar. Two countries that share a weekend and happen to have the same closure-free month can still run very different years, and South Africa is placed as follows.

Across 2027 the South African public closures fall 4 in Q1, 2 in Q2, 2 in Q3, and 2 in Q4. A further two holidays land on the Saturday and Sunday weekend and cost no working day at all, which is why a country's holiday count and its working-day loss are different numbers.

The longest uninterrupted run in the 2027 calendar sits between September 24, 2027 and December 16, 2027, 83 calendar days with no South African public closure in between. Stretches like that are where multi-week work belongs, and they move from year to year whenever a movable holiday does.

Where the month sits in the year's closure pattern

Closures are not spread evenly across a calendar year. They cluster around fixed anniversaries and around whichever lunar or movable feasts a jurisdiction observes, so two adjacent months can carry very different loads, and the South African public calendar is no exception.

2027 opens its South African public closures with New Year's Day on January 1, 2027 and ends them with Day of Goodwill (observed) on December 27, 2027. The densest month of the year is March 2027 with three closures on working days.

One working day more than last year

There is one more working day in August 2027 than in August 2026: 21 against 20. A single-day swing is the ordinary case, produced by the calendar shifting forward one weekday between consecutive common years, and it is large enough to matter to a monthly target and small enough to be missed.

August opens 2026 on a Saturday, 2027 on a Sunday, and 2028 on a Tuesday. That movement, one weekday in a common year and two after a leap day, is what makes the three counts differ. The number of closures on working days is the same in both years, so the whole of any difference comes from weekday alignment. Looking ahead, August 2028 carries 22 working days.

Where the month's anchor dates fall

Two of the common monthly anchor dates in August 2027 land outside the working week or on a closure. The table below resolves each one against the South African public calendar, together with the first working day on or after it.

The final column is arithmetic, not a legal conclusion. Whether an obligation actually moves when its date is not a working day depends on the instrument that sets it, and this site does not assume a shift rule for any jurisdiction. Where a rule is known it is stated in the holiday data methodology and on the country page it applies to.

Net terms dated in August 2027

An invoice dated the 1st of August on calendar-day Net 30 terms comes due on August 31, 2027, a working day under the South African public calendar. Terms counted in calendar days move independently of the working week, so the same term written on two consecutive months can settle cleanly in one and roll across a closure in the other.

Invoice dateNet 30, calendar daysNet 60, calendar days
Dated August 1August 31, 2027September 30, 2027

Dated August 31September 30, 2027October 30, 2027 (rolls to November 1, 2027)

Net 30 and Net 60 are commercial conventions rather than statutory periods, and both are counted here in calendar days, which is how they are almost always written. Where a contract counts in working days instead, use the between-dates calculator with the South Africa calendar selected, because the two produce different dates whenever a closure falls inside the term.

Frequently Asked Questions

How many business days are in August 2027 under the South African public holiday calendar?
August 2027 has 21 working days under the South African public holiday calendar. The month spans 31 calendar days, of which 9 fall on a weekend and 1 is a South African public holiday that lands on a weekday. The remaining 21 weekdays are countable as working days for invoicing, deadline tracking, and contract math.
Which South Africa holidays affect August 2027?
August 2027 contains one South African public holiday: National Women's Day on Monday, August 9. The calculator skips it. Regional or industry-specific closures may add further non-working days for narrower contract definitions; layer them into the calculator's Advanced options if needed.
How does the Sunday rule work under the Public Holidays Act?
Section 2(1) of the Public Holidays Act 36 of 1994 makes the Monday after a public holiday that falls on a Sunday a public holiday too. The Act has no rule for a holiday that falls on a Saturday, which stays on the Saturday. Where a public holiday falls on a Sunday, this site's South African data lists the Monday and not the Sunday.
Is a public holiday a business day for a bill of exchange?
No. Section 3 of the Public Holidays Act deems Sunday and any public holiday a non-business day within the meaning of any law relating to bills of exchange or promissory notes. Saturday is not named in section 3. Under section 1(2), a reference to public holidays in any other law is a reference to the public holidays this Act defines.
Why does the business-day count vary year to year?
Two things shift the monthly count for South Africa. First, the day of the week the first of the month lands on changes the count of each weekday. Second, South African public holidays anchored to a fixed date shift their weekday across years. Some years a fixed-date holiday lands on a weekend; some countries shift the observance to an adjacent weekday and some absorb it into the weekend. August 2026 had 20 working days, so August 2027 has 1 more working day year over year.
When is the last working day of August 2027?
The last working day of August 2027 under the South African public calendar is Tuesday, August 31. The month's last calendar day is Tuesday, August 31, so the two are the same date this year. Counting back, the third-to-last working day is Friday, August 27.
How many working days in a row does August 2027 offer?
August 2027 has 21 working days in total, but they do not run consecutively. They arrive in five stretches of 5, 4, 5, 5, and 2 days, so the longest unbroken run is five days, from August 2 to August 6. No working day in the month is isolated between two closures.
