Void Years, Explained: How NFL Teams Borrow From the Future
A void year is a season that exists only in a spreadsheet. Teams add them to park signing-bonus money somewhere the salary cap cannot reach it yet.
The Miami Dolphins will spend about $182 million in 2026 on players who are not on the roster. Sixteen of them, including two who last suited up for the club in Week 18 of the 2024 season. The single largest piece is Tua Tagovailoa's $99.2 million, the biggest dead cap figure attached to any player in league history.
That is what deferral looks like when the deferral runs out. And the mechanism most responsible for pushing NFL money into seasons that have not happened yet is a piece of accounting fiction called the void year.
What are void years in an NFL contract?
They are contract seasons the player will never play. Jason Fitzgerald, who tracks them at Over the Cap more closely than anyone, calls a void year a fake contract year used for the sole purpose of parking salary cap charges.
A SumerSports breakdown of the mechanic puts it structurally: void years are placeholders for prorated signing bonus money.
The reason they exist is a single accounting rule. A signing bonus is paid up front in cash, but for cap purposes it is spread evenly across the contract's seasons. A three-year deal gives you three slices. Bolt two phantom seasons onto the end and the same bonus becomes five thinner slices, which means a smaller cap hit today and a roster you could not otherwise afford.
The cash does not change. Only the paperwork does.
How many void years can a team add?
Five minus the years actually left on the deal. A signing bonus can be prorated across a maximum of five seasons, so the ceiling on phantom years is whatever gets a contract to five. A one-year contract can carry four void years. A four-year contract can carry one.
Teams like the arrangement because it stretches a competitive window. Players sometimes like it because the dummy salaries in those void seasons set a marker for future negotiations. And front offices like it enough that Over the Cap counted 73 contracts scheduled to void automatically in a single league year, with roughly 80% of them voiding rather than being renegotiated away.
What happens when the void years hit?
Everything parked in them accelerates at once.
The cleanest illustration is Kirk Cousins, whose remaining Vikings deal SumerSports laid out year by year: $10.25 million of prorated bonus in 2023, then void seasons carrying $10.25 million, $10.25 million, $4 million and $4 million. When the contract voided, $28.5 million landed on Minnesota's 2024 cap for a quarterback no longer playing there. Some of that proration was left over from a 2022 extension; the rest came from a 2023 restructure that had already pushed money forward once.
There is a trap inside the trap. Those inflated dummy base salaries in the void years, the ones nobody ever intends to pay, cap what the player can be offered in an extension, because the collective bargaining agreement bars a player from signing a new deal with a raise within a year of signing the last one. Teams have occasionally negotiated themselves out of retaining their own player.

Tagovailoa's charge did not come from void years; it came from a release, which triggers the same acceleration. But the shape is identical, and it shows how the rules interact. Because Miami designated him a post-June 1 cut, the club can split the acceleration across two seasons: $55.4 million against the 2026 cap, $43.8 million against 2027. Seven separate players carry dead cap hits above $10 million on that roster.
None of this is cheating. It is the cap working exactly as written, which is the part fans find hardest to accept. The cap does not stop a team from spending; it only dictates when the spending is counted. A general manager who fills void years with bonus proration is making a bet that the cap will be larger later, that the roster will be better now, and that somebody, possibly not him, will be standing there when the acceleration arrives.
Sometimes the bet works. Teams facing a lean year can absorb the hit with unused space carried forward from a previous season, a mechanic we broke down in how NFL salary cap rollover actually works. Sometimes it does not, and a franchise spends a season paying $182 million for football played somewhere else, by men wearing other uniforms, while the general manager who signed the checks watches from a different building.
