My current salary is a personal matter (with humor). Or I feel that my current salary should not be included in the factors for getting hired.

Asking how much you currently make is a legitimate question. If you don’t answer it or deflect it, the company can ask your previous employer. In the USA it is a legal question. If you deflect the question or refuse to answer it, this might place a negative tone during your interview.

I agree with the “guest” answer, your current salary shouldn’t be a factor for getting the job you’re interviewing for, but the salary YOU WANT certainly will be a factor.

During your job search you should have a salary range in mind that you would accept. When a company has a position open they have already gone through a process of defining the need for the position, the core skills required of the job, and the annual budget they have allocated for the position. You may want more than what the prospective employer set aside, but that get’s into the negotiating phase which comes a day or two after an initial offer has been made.

If you don’t want them to know your salary because it is LOWER than what you’re looking to make, here is a way to answer the questions while marketing your skills.

Example:
“I currently earn $65K and have a valuable benefits package. With my extensive experience and the skills I have acquired in [name the field or name specific expertise] telecommunications including my extensive training and expert-level knowledge of all the modern smartphones, I am in the process of better aligning my skill level with my annual salary.”


If you don’t want them to know your salary because it is much HIGHER than what you’re looking to make, here is a way to answer the question.

“I currently earn $125K per year, but I am not looking at this opportunity for the salary it pays. I have always lived below my means and I want work that is satisfying and where I know I am helping the company grow. The quality of my work life is more important to me than the how much I earn.”

the previous answer sums it up pretty good.
I've used the following in my previous interviews:

My last salary was updated year / year and half ago so naturally it does not reflect the current skills and experience.
another issue is when you change your title , for example from a developer to a team leader , then it is clear that the salary should reflect that.

In addition , i don't think it's wrong to state that you are looking to upgrade yourself financially , after all you are a family man.
although i would sate that money is important but it's not the main factor.

Agreed. In recruitment, relationships are built on trust and honesty when it comes to experience, goals and salary history. I tend to have a "help me help you" approach, and if the candidate chooses not to be open in return, it's a serious red flag.

I work for Marlabs Inc. which keeps too much margin between client and them.
I am getting same what I was getting two years back and I am really frustrated after having so many years of experience. I am looking for an opportunity in east coast but this company just allow me to work where they make good money.

I agree that it is reasonable for an employer to ask this question. As job seekers, it is also reasonable for us to try to increase our income. As such, I find it useful to state a range when possible, though the direct "current salary" question doesn't allow for that.

Another approach to this is to arm ourselves with accurate market data. Consult free sites like payscale.com, salary.com, or even Glassdoor.com to get a better idea of what the market salary ranges should be in your area.

Personally, if I am asked this question, I just lie. I have a salary in mind and I am confident that it accurately reflects my skills and experience. I know what other people like me are getting paid and what is being offered out there.

My previous employer froze everybody's salaries for three years "because of the recession". My starting salary with them was reasonable for an entry-level role. However, back when I started with them, nobody expected a major recession, so naturally I hoped my salary was going to increase with time, which did not happen. I've had enough and I am looking for a job that will pay what I am worth.

I don't want my future employer to look at my previous salary and say: "How can you justify such a large increase?" So I just lie a little bit (15% or so). I tell them I want a range of between X and Y, and that my previous salary was equal to the bottom of that range. Once it gets to the offer and they really want you, they aren't going to fret about your previous salary, especially if your expectations are reasonable. At the end of the day, what matters to them is the market rate -- can they get someone else with the same skills who will accept a lower salary, or not?
