A health savings account (HSA) is a tax-advantaged medical savings account available to taxpayers in the United States who are enrolled in a high-deductible health plan (HDHP). The funds contributed to an account are not subject to federal income tax at the time of deposit. Unlike a flexible spending account (FSA), HSA funds roll over and accumulate year to year if not spent. HSAs are owned by the individual, which differentiates them from company-owned Health Reimbursement Arrangements (HRA) that are an alternate tax-deductible source of funds paired with either HDHPs or standard health plans. HSA funds may currently be used to pay for qualified medical expenses at any time without federal tax liability or penalty. Beginning in early 2011 OTC (over the counter) medications cannot be paid with HSA dollars without a doctor's prescription. Withdrawals for non-medical expenses are treated very similarly to those in an individual retirement account (IRA) in that they may provide tax advantages if taken after retirement age, and they incur penalties if taken earlier. These accounts are a component of consumer-driven health care.
Saving accounts (UK: savings accounts) are accounts maintained by retail financial institutions that pay interest but cannot be used directly as money in the narrow sense of a medium of exchange (for example, by writing a cheque). These accounts let customers set aside a portion of their liquid assets while earning a monetary return. For the bank, money in a savings account may not be callable immediately and, in some jurisdictions, does not incur a reserve requirement. Cash in the bank's vaults may thus be used, for example, to fund interest-paying loans.
The other major types of deposit account are the transactional account (usually known as a "checking" (US) or "current" (UK) account), money market account and time deposit.
In the United States, under Regulation D, 12 (CFR) §204.2(d)(2), the term "savings deposit" includes a deposit or an account that meets the requirements of Sec. 204.2(d)(1) and from under the terms of the deposit contract or by practice of the depository institution, the depositor is permitted to make up to six pre-authorized transfers or withdrawals per month or a statement cycle of at least four weeks. There is no regulation limiting number of deposits into the account.
