Paul assures us that God wills all men to be saved (1 Tim. 2:4). He must then have provided the means for that will to be accomplished, which means salvation must be at least possible for everyone.
In His wisdom, Jesus did not want to leave us
orphans and unaware of our need for salvation, therefore
He established the priesthood as a perpetual reminder of the gift of salvation He won for us on the Cross.
Secondly, is there are way for a non-Catholic sinner to know that he or she has been permanently reconciled to God that does not entail joining only the Roman Catholic church and giving alms to it?
One will know for sure upon death.
Obviously live a sin free life with the help of the Sacraments.
God is the judge and will see what is in one’s heart and will have mercy but be fair.
I personally feel that a baptized Catholic that leaves the Catholic church will have trouble.
Many are invited, but few are chosen.
Here is an answer to your question:

However, for those who knowingly and deliberately (that is, not out of innocent ignorance) commit the sins of heresy (rejecting divinely revealed doctrine) or schism (separating from the Catholic Church and/or joining a schismatic church), no salvation would be possible until they repented and returned to live in Catholic unity.
The Catholic church is entirely a voluntary organization and their is no legal requirement to contribute to the Church, yes a moral one to support the local parish. I am not aware of anyone being prevented from participating in the Catholic Church because of any requirement of giving alms.
Sincere questions for you or any Catholic reading this thread.
I do hope that this is a sincere question and I have tried to answer as honestly as I can
There were several articles reference in posts 7, 9, 10 and 23 that may also help.

All will fail to get you to heaven and you will continue along your way to Hell.
Christ alone, through faith alone in His completed sacrifice, will bring you to heaven.
For God so loved the world, that He gave His only begotten Son, that whoever believes in Him shall not perish, but have eternal life. 17“For God did not send the Son into the world to judge the world, but that the world might be saved through Him. 18“He who believes in Him is not judged; he who does not believe has been judged already, because he has not believed in the name of the only begotten Son of God. 19“This is the judgment, that the Light has come into the world, and men loved the darkness rather than the Light, for their deeds were evil. 20“For everyone who does evil hates the Light, and does not come to the Light for fear that his deeds will be exposed. 21“But he who practices the truth comes to the Light, so that his deeds may be manifested as having been wrought in God.”
John, as moved by the Hoky Spirit, has written this and other passages to give us the assurance of our salvation. We need not live in fear.
