Regarding donation to NGO/Trust.

Option1)
Pure Donation with service charge of 2% in advance.
Per year 5cr ( For 3 financial year ).
Welcome letter or confirmation letter will be given by donar company after receiving request letter.
Reference: ngobox.org, crsbox.org, indiacsr.in

Option2)
Conversation Mode.
This we have to match the conditions and protocols of both sender and Receiver.

Sender ( company) : Who needs liquid cash (black money) for his various requirement.
Example: To invest in cash trade, to give bribe for aquiring any projects through government, invest in real estate where 30 to 50% still in cash mode, etc, etc.

Receiver (Trust/ NGO's/ society) : Trust or the Funder holding the black money get his black converted to white and later take it in his account with GST utilizing the projects of trust.
Funders doesn't always depends on NGO's for parking and conversion as there are many other platforms.
So be careful with requirement of both sender and Receiver and then commit to work.

Regarding donations : If it's for tax exemption only 10% of total income is eligible by individual or salaried or company or any organization subject to their ITR. Above that no exemption.

Example: If person income is 10 lakh.
He can donate 1 lakh and get 50k return after filling ITR with donation receipt only.

If company income is 100 cr.
They can donate only 10cr to get claim 5 cr back under 80G.
( If you see in NSE, BSE and other listed companies income per annum, you come to know it's only few companies have the eligibility to donate 100cr above).
Moreover those big companies will not donate outside unless they need of cash because they all have their own ngo and foundations, like reliance foundation, hcl foundation, Infosys, foundation, bharti foundation, etc).
NOTE: Section 35, no excemptions ( it was valid to claim before March 2018).

Very important note:
People confuse with trade profit surplus, csr, other income, etc.
However it's only two things.
1) CSR ( As per company act 2013, every company must spend minimum of 2% of net profit and maximum to their wish, no exemption from tax so usually they spend only 2% )
2) PROFIT INCOME ( Any kind of trade & trading, surplus, carryover, business profit etc).
As per RBI, Sebi, IT& CBDT guidelines only.

Final NOTE: Do not waste time unless untill you know the donar company requirement and background.
Also NGO's requirement and their cash availability.

Since its completely a conversion mode, there are so many other ways for both who need accountable and who need cash so please ensure you are not wasting g your time and others without proper knowledge and requirement.
Unless untill you meet the end person you well not be aware of the requirement.
Heard of mouth from person to person is waste of time.
